Bell jurors ordered to begin anew after panelist is dismissed

After nearly five days of deliberations, jurors in the Bell corruption trial were ordered Thursday to begin anew after a member of the panel was dismissed for misconduct and replaced by an alternate.

The original juror, a white-haired woman identified only as Juror No. 3, told Los Angeles County Superior Court Judge Kathleen Kennedy she had gone onto a legal website to look up jury instructions and then asked her daughter to help find a definition for the word "coercion."

Although all but one defense attorney requested that the woman stay, Kennedy said the juror needed to be removed. "She has spoken about the deliberations with her daughter, she has conducted research on the Internet, and I've repeatedly, repeatedly throughout this trial — probably hundreds of times — cautioned the jury not to do that," the judge said.

The removal came after jurors notified the judge that they were deadlocked and that continued deliberations seemed fruitless.

It was unclear how to interpret the day's events, whether the dismissed juror had been a lone holdout or an indication of a fractured jury.

The juror started to tell the judge which way she was leaning in the case, saying she had gone online "looking to see at what point can I get the harassment to stop.... How long do I have to stay in there and deliberate with them when I have made my decision that I didn't think there was —"

Kennedy cut her off before she could finish.

The woman clasped her hands over her mouth and said, "I'm sorry."

Two defense attorneys thought she was leaning toward acquittal and wanted her to stay. "I would have preferred the deadlock to a guilty verdict," said Alex Kessel, the attorney for George Mirabal, one of six former council members charged with misappropriation of public funds.

The council members are charged with inflating their salaries in what prosecutors contend was a far-reaching web of corruption in which fat paychecks were placed ahead of the needs of the city's largely immigrant, working-poor constituents.

When attorneys and defendants were summoned to the courtroom Thursday morning, they were initially told that the jury appeared to be deadlocked.

"Your honor, we have reached a point where as a jury we have fundamental disagreements and cannot reach a unanimous verdict in this case," read a note signed by two jurors, including the foreman, that was given to Kennedy.

A note from another juror alerted the judge that Juror No. 3 had consulted an outside attorney. That did not appear to be the case, but her other actions were revealed under questioning from the judge.

The same juror made a tearful request Monday to be removed from the panel because she felt others were picking on her. Kennedy told the woman that although discussions can get heated, it was important to continue deliberating.

On Thursday, however, the juror again broke into tears and said she had spoken with her daughter about "the abuse I have suffered." She said her daughter told her, "Mom, they're trying to find the weak link."

The woman said she had turned to the Internet to better understand the rules about jury deliberations and came across the word "coercion." After her daughter helped her look up the word's definition, she wrote it down on a piece of paper and brought it with her to court. When the judge asked to see the paper she went into the jury room to retrieve it.

The woman later left the courtroom in tears.

With an alternate in place, Kennedy told the panel to act as if the earlier deliberations had not taken place. The alternate had sat in the jury box during the four-week trial but did not take part in deliberations.

Former council members Luis Artiga, Victor Bello, George Cole, Oscar Hernandez, Teresa Jacobo and Mirabal are accused of drawing annual salaries of as much as $100,000 a year by serving on boards that did little work and seldom met, part of a scandal that drew national attention to the small city in 2010.

Prosecutors said that Bell's charter follows state law regarding council members' compensation. In a city the size of Bell, council members should be paid no more than $8,076 a year.

The trial began in late January, and the case went to the jury last Friday.

As the jury resumed deliberations in downtown Los Angeles, the verdict was clearly in on the streets of Bell.

One resident unfurled old protest banners and signs from the days when the pay scandal was first exposed and then called former members of an activist group that had led the charge for reform in the city.

"We're holding our breaths and waiting," Denise Rodarte, a member of the grassroots group Bell Assn. to Stop the Abuse, said in regard to a verdict.

"It's cut and dry: Local elected officials were supposed to make a certain amount of money, and they made a lot more."

SpaceX Reaches Orbit, But Problem Delays Power Supply

Update 10:40 a.m. EST: The Dragon spacecraft is in the proper orbit, but there is a problem with the spacecraft itself. Elon Musk messaged that there is an “issue with Dragon thruster pods. System inhibiting three of four from initializing. About to command inhibit override.” More details will be provided as they become available.

Update 11:10 a.m. EST: It appears the problem with the thrusters on the Dragon is keeping SpaceX from  deploying the solar arrays. There is 18 hours of battery life on board the Dragon which can be used during the flight, but for more duration, the solar arrays are needed to generate power. Elon Musk’s latest tweet reads, “Holding on solar array deployment until at least two thruster pods are active.”

Update 11:50 a.m. EST: SpaceX waited until the Dragon was over a ground station in Australia to communicate with the spacecraft, overriding an inhibit instruction that was preventing two of the three thruster pods from working properly. The pressure in one of the two inoperative thruster pods was “trending positive” according to Musk and the team was able to successfully deploy the Dragon’s 54 foot wide solar arrays which will allow the spacecraft to generate electrical power. SpaceX says the delay in the deployment means there “may be a rearrangement of the planned burn sequences for the Dragon spacecraft” as it approaches the ISS.

SpaceX successfully launched its third flight to the International Space Station this morning carrying more than 1,200 pounds of cargo as part of the company’s ongoing orbital trucking contract with NASA. This morning’s launch was the first daytime launch of the Falcon 9 from Cape Canaveral, with the liftoff taking place at 10:10 a.m. EST.

After a hotfire test on Monday, the Falcon 9 was returned to its hangar at launch complex 40 earlier this week where final preparations were made for today’s launch. This is the third flight of the Dragon spacecraft to the ISS, but just the second contracted cargo mission for NASA. The first flight last May was a demonstration mission, though a small amount of cargo was delivered.

At the pre-launch press conference on Thursday, SpaceX’s Shotwell explained for the first time the root cause of the engine shutdown during the last Falcon 9 launch to the ISS in October. She said the SpaceX team traced the problem to a “material flaw in the jacket of the engine.”

Shotwell did not elaborate on the nature of the flaw saying a final report was still being wrapped up and that the rocket engines are one of the main things covered by the International Trade in Arms Regulations (ITAR) the company must follow.

“I don’t look good in horizontal stripes,” she said half jokingly since breaking ITAR regulations could result in jail time, “and I want to see my kids graduate from college.”

The flaw in the jacket of the engine led to a breech causing a “depressurization in the combustion chamber. Though the engine did not explode as initially thought, Shotwell was quick to point out the upside to the failure. She told reporters the engine shutdown did show the redundancy in the Falcon 9 design works.

“Though you never necessarily want to see it happen,” she said of the eight (out of nine) engine boost to orbit, “it’s nice that we’ve demonstrated the vehicle as it was designed.”

Today’s flight includes numerous scientific experiments, including one that will be both carried up by the Dragon spacecraft, and carried back to earth when Dragon departs the ISS. The return schedule is partly dependent on the successful completion of the research according to NASA.

In addition to the scientific cargo on board today’s flight, there are some crew care items including fresh apples from an orchard belonging to a SpaceX employee’s family according to SpaceX president Gwynne Shotwell.

“It’s a little bit healthier, I think, than the one that NASA sent last time,” she said referring to the ice cream sent on the last Dragon spacecraft.

The flight also marks the first time cargo will be carried in the unpressurized trunk of the spacecraft. All of the cargo on the first two flights was carried inside the Dragon capsule which is designed for human passengers. But the spacecraft also has room for cargo in the cylindrical section beneath the Dragon. On this flight a pair of grapple bars that will be used on the ISS are being carried in the unpressurized section.

In addition to a few firsts, today’s launch marks the last time SpaceX plans on using the first version of its Falcon 9 rocket. Beginning this fall, the launch company plans on using v1.1 of the Falcon 9 with upgraded Merlin engines which will be arranged in a circular pattern rather than the 3×3 grid used on v1.0.

Today’s rocket is familiar to Wired readers as it was being built in the SpaceX factory when we visited last spring, and was undergoing testing at the company’s testing facility in Texas when we watched the new Merlin engines being tested last summer. Right now the Falcon 9 and Dragon capsule are not used again, but SpaceX plans to use the hardware for multiple flights in the future.

Unlike the previous two flights to station which took more than a day, because of the phasing between launch and the orbit of the ISS, NASA expects Dragon to dock with the station about 20 hours after liftoff.

There are six astronauts on board the ISS right now, but three of them will return to earth aboard a Russian Soyuz capsule while the Dragon is on station. The SpaceX capsule is scheduled to return itself with more than a ton of cargo on March 25th.

The New Old Age Blog: Why Can’t I Live With People Like Me?

“Aging in place” is the mantra of long-term care. Whether looking at reams of survey data, talking to friends or wishing on a star, who among us wouldn’t rather spend the final years — golden or less so — at home, surrounded by our cherished possessions, in our own bed, no cranky old coot as a roommate, no institutional smells or sounds, no lukewarm meals on a schedule of someone else’s making?

That works best, experts tell us, in dense cities, where we can hail a cab at curbside, call the superintendent when something breaks and have our food delivered from Fresh Direct or countless takeout restaurants. We’d have neighbors in the apartment above us, below us, just on the other side of the wall. Hearing their toilets flush and their children ride tricycles on uncarpeted floors is a small inconvenience compared to the security of knowing they are so close by in an emergency.

Urban planners, mindful that most Americans live in sprawling, car-reliant suburbs, are designing more elder-friendly, walkable communities, far from “real” cities. Houses and apartments are built around village greens, with pockets of commerce instead of distant strip malls. Some have community centers for congregate meals and activities; others share gardens, where people can get their hands in the warm spring dirt long after they can push a lawn mower.

All of this is a step in the right direction, despite the Potemkin-village look of so many of them. But it doesn’t take into account those who are too infirm to stay at home, even in cities or more manageable suburban environments. Some are alone, others with a loving spouse who by comparison is “well” but may not be for long, given the rigors of care-taking. It doesn’t take into account people who can’t afford a home health aide, who don’t qualify for a visiting nurse, who have no adult children to help them or whose children live far away.

But by now, aging in place, unrealistic for some, scary or unsafe for others and potentially very isolating, has become so entrenched as the right way to live out one’s life that not being able to pull it off seems a failure, yet another defeat at a time when defeats are all too plentiful. Are we making people feel guilty if they can’t stay at home, or don’t want to? Are we discouraging an array of other solutions by investing so much, program-wise and emotionally, in this sine qua non?

Regular readers of The New Old Age know that I am single, childless and terrified of falling off a ladder while replacing a light bulb, breaking a hip and lying on the floor, unattended, until my dog wails so loudly a neighbor comes by to complain. A MedicAlert pendant is not something that appeals to me at 65, but even if I give in to that, say at 75, I’m not sure my life will be richer for digging my heels in and insisting home is where I should be.

So I spend a lot of time thinking about the alternatives. I know enough to distinguish between naturally-occurring-retirement communities, or NORCs (some of which work better than others); age-restricted housing complexes (with no services); assisted living (which works fine when you don’t really need it and not so fine when you do); and continuing care retirement communities (which require big upfront payments and extensive due diligence to be sure the place doesn’t go belly up after you get there).

What I find so unappealing about all these choices is that each means growing old among people with whom I share no history. In these congregate settings, for the most part, people are guaranteed only two things in common: age and infirmity. Which brings us to what is known in the trade as “affinity” or “niche” communities,” long studied by Andrew J. Carle at the College of Health and Human Services at George Mason University in Fairfax, Va.

Mr. Carle, who trains future administrators of senior housing complexes, was a media darling a few years back, before the recession, with the first baby boomers approaching 65 and niche communities that included services for the elderly — not merely warm-weather developments adjacent to golf courses — expected to explode. In newspaper interviews as recently as 2011, Mr. Carle said there were “about 100 of them in existence or on the drawing board,” not counting the large number of military old-age communities.

Mr. Carle still believes that better economic times, when they come, will reinvigorate this sector of senior housing, after the failure of some in the planning stages and others in operation. In an e-mail exchange, Mr. Carle said there were now about 70 in operation, with perhaps 50 of those that he has defined as University Based Retirement Communities, adjacent to campuses and popular with alumni, as well as non-alumni, who enjoy proximity to the intellectual and athletic activities. Among the most popular are those near Dartmouth, Oberlin, the University of Alabama, Penn State, Notre Dame, Stanford and Cornell.

At the height of the “affinity” boom, L.G.B.T.-assisted living communities and nursing homes were all the rage, seen as a solution to the shoddy treatment that those of different sexual orientations in the pre-Stonewall generation experienced in generic facilities. A few failed, most never got built and, by all accounts, the only one to survive is the pricy Rainbow Vision community in Sante Fe, N.M.

A handful of nudist elder communities, and ones for old hippies, also fell by the wayside, perhaps too free-spirited for the task. According to Mr. Carle, despite the odds, at least one group of RV enthusiasts has added an assisted-living component to what began as collections of transient elderly, looking only for a parking spot and necessary water and power hook-ups for their trailers. Native Americans have made a go of an assisted-living community in Montana, and Asians have done the same in Northern California.

But professional affinity communities, which I find most appealing, are few and far between.

The storied Motion Picture & Television Country House and Hospital, a sliding-scale institution in the San Fernando Valley since 1940, survived near-closure in 2009 as a result of litigation, activism by the Screen Actors Guild and the local chapter of the Teamsters, and news media pressure. Among film legends who died there — along with cameramen, back-lot security guards and extras — were Mary Astor, Joel McCrea, Yvonne De Carlo and Stepin Fetchit.

New York State’s volunteer firefighters are all welcome to a refurbished facility in the Catskill region that offers far more in the way of care and activities, including a state-of-the-art gym, than when I visited there five years ago. At that time, the residents amused themselves by activating the fire alarm to summon the local hook and ladder company, which didn’t mind a bit.

Then there is Nalcrest, the retirement home for unionized letter carriers. Even as post offices nationwide are preparing to eliminate Saturday service, and snail mail becomes an artifact, the National Association of Letter Carriers holds monthly fees around the $500 mark, is located in central Florida so its members no longer have to brave rain and sleet to complete their appointed rounds, and bans dogs, the bane of their existence.

So why not aged journalists? We surely have war stories to embroider as we rock on the porch. Perhaps a mimeograph machine to produce an old-fashioned, dead-tree newspaper, which some of us will miss once it has given way to Web sites like this one. Pneumatic tubes, one colleague suggested, to whisk our belongings upstairs when we can no longer carry them. Other colleagues wondered about welcoming both editors and reporters. How can these two groups, which some consider natural adversaries, complain about each others’ tin ears or missed deadlines if we’re not segregated?

I disagree. The joy of this profession is its collaboration. We did the impossible day after day when young. We belong together when old.

Detroit Car Sales Climb Again

General Motors reported a 7 percent gain in auto sales in the United States in February, beating several analyst estimates on the strength of its crossover models and pickup trucks, while Detroit rival Ford Motor Co. posted a slightly weaker-than-expected 9.0 percent gain.

G.M. sold 224,314 cars and trucks last month. Sales of its Chevrolet Silverado pickup trucks jumped nearly 30 percent, while its Chevrolet Equinox midsize crossover rose 16 percent.

G.M., the largest Detroit automaker, also predicted that the overall auto industry’s sales rate this month would be 15.5 million, better than the 15.1 million sales rate expected by economists polled by Thomson Reuters.

Ford said its American auto sales rose to 195,822 cars and trucks in February. The No. 2 automaker reported a 21 percent gain in sales of its crossover and sport-utility vehicles while its F-Series trucks saw a 15.3 percent gain.

But Ford’s car sales rose 6.4 percent, hurt by a 11 percent drop in the Focus compact car and a 9 percent drop in the Fiesta subcompact. Trucks overall, including the E-Series and heavy trucks, rose 3.6 percent during the month.

Chrysler Group, the third-largest Detroit automaker, said its United States sales rose 4 percent to 139,015 in February, slightly less than some analysts expected. Volkswagen’s American unit posted a 2.9 percent increase to 31,456 vehicle sales.

Auto sales each month are an early indicator of the consumer spending. Industry sales in February were expected to show a fourth straight month of seasonally adjusted annualized sales above 15 million vehicles, for the first time since early 2008, a sign of a sustained recovery after the recession.

Chrysler estimated the month will finish at 15.5 million, including medium and heavy trucks, which typically add 300,000 vehicles to the monthly sales rate.

DNA science points to better treatment for acne

Ancient Egyptians were vexed by it, using sulfur to dry it out. Shakespeare wrote of its "bubukles, and whelks, and knobs, and flames o' fire."

Today, acne plagues us still. Doctors can cure some cancers and transplant vital organs like hearts, but they still have trouble getting rid of the pimples and splotches that plague 85% of us at some time in our lives — usually, when we're teenagers and particularly sensitive about they way we look.

But new research hints that there's hope for zapping zits in the future, thanks to advances in genetic research.

Using state-of-the-art DNA sequencing techniques to evaluate the bacteria lurking in the pores of 101 study volunteers' noses, scientists discovered a particular strain of Propionibacterium acnes bacteria that may be able to defend against other versions of P. acnes that pack a bigger breakout-causing punch.

As best as dermatologists can tell, zits occur when bacteria that reside in human skin, including P. acnes, feed on oils in the pores and prompt an immune response that results in red, sometimes pus-filled bumps. But the study subjects who had the newly discovered bacterial strain weren't suffering from whiteheads or blackheads, according to a report published Thursday in the Journal of Investigative Dermatology.

Someday, the realization that "not all P. acnes are created equal" might help dermatologists devise treatments that more precisely target bad strains while allowing beneficial ones to thrive, said Dr. Noah Craft, a dermatologist at the Los Angeles Biomedical Research Institute who conducted the study with colleagues from UCLA and Washington University in St. Louis.

Doctors might prescribe probiotic creams that deliver "good" P. acnes to the face the same way a daily serving of yogurt helps restore healthy bacteria in the digestive tract.

"There are healthy strains that we need on our skin," Craft said. "The idea that you'd use a nuclear bomb to kill everything — what we're currently doing with antibiotics and other treatments — just doesn't make sense."

The research is part of a broad effort backed by the National Institutes of Health to characterize the so-called human microbiome: the trillions of microbes that live in and on our bodies and evolve along with us, sometimes causing illness and often promoting good health.

Most of the microbiome attention so far has gone to studying species in the gut, said study leader Huiying Li, an assistant professor of molecular and medical pharmacology at UCLA's Geffen School of Medicine. But the NIH's Human Microbiome Project, which funds her research, also looks at microbial communities in the nasal passages, the mouth, the urogenital tract and the skin.

Li said she became interested in studying acne because the skin microbiome seemed particularly understudied.

The research team recruited 101 patients in their teens and 20s from dermatology clinics in Southern California. Among them, 49 had acne and 52 had "normal skin" and were not experiencing breakouts but had come to the clinics for other problems.

Doctors used adhesive pore strips to remove skin bacteria from patients' noses. The researchers then collected the waxy plugs — a combination of bacteria, oils, dead skin cells and other stuff — and used DNA to figure out which bacteria were present.

They found that the P. acnes species accounted for about 90% of the bacteria in pores, in both healthy patients and acne sufferers. Digging a little deeper into the DNA, they found that two particular strains appeared in about 20% of acne sufferers, while a third strain was found only in acne-free patients.

"Dogs are dogs, but a Chihuahua isn't a Great Dane," Craft said. "People with acne had pit bulls on their skin. Healthy people had poodles."

The team then sequenced the complete genomes — about 2.6 million base pairs apiece — of 66 of the P. acnes specimens to explore in more depth how the good and bad strains differed.

The two notable bad strains had genes, probably picked up from other bacteria or viruses, that are thought to change the shape of a microbe to make it more virulent. The researchers hypothesized that the foreign DNA, perhaps by sticking more effectively to human host tissues, may help trigger an inflammatory response in the skin: acne.

The good strain, on the other hand, contained an element known to work like an immune system in bacteria, Li said. Perhaps it allows this P. acne to fight off intruders and prevent pimples from forming.

Li said the researchers did not know why some people had the bad P. acnes strains and others did not, and whether genetics or environment played a bigger role.

Dr. Vincent Young, who conducts microbiome research at the University of Michigan Medical School but wasn't involved in the acne project, said advances in sequencing technology and analysis made the new study possible. In the past, he said, scientists wouldn't have tried to sequence dozens of genomes in a single species.

"They'd say, why waste the money?" he said. "Now you can do this in a couple of days."

Li and Craft — neither of whom suffered bad acne as teens — plan to keep up the work.

More research is needed to come up with super-targeted anti-microbial therapies, or to develop a probiotic cream for acne sufferers.

Craft continues collecting samples from patients' pores. He hopes to study whether twins share the same microbial profiles, how acne severity is reflected in bacteria populations, and how things change in a single patient over the course of a treatment regimen.

One of the study volunteers, 19-year-old UC Santa Cruz student Brandon Pritzker, said he would have loved to have treated his acne without affecting the rest of his body. When he took Accutane, he suffered back pain and mood shifts.

Now off the drug, Pritzker said he is at peace with his pimples. "I still have breakouts, but I figure I'm 19, that's the way it's going to be," he said.

But, he added, "it hindered my confidence at the time. Kids with clear skin are probably a little happier."

Rodent Mind Meld: Scientists Wire Two Rats' Brains Together

It’s not exactly a Vulcan mind meld, but it’s not far off. Scientists have wired the brains of two rats together and shown that signals from one rat’s brain can help the second rat solve a problem it would otherwise have no clue how to solve.

The rats were in different cages with no way to communicate other than through the electrodes implanted in their brains. The transfer of information from brain to brain even worked with two rats separated by thousands of kilometers, one in a lab in North Carolina and another in a lab in Brazil.

“We basically created a computational unit out of two brains,” says neuroscientist Miguel Nicolelis of Duke University, who led the study.

Nicolelis is a leading figure in brain-machine interface research and the man behind a bold plan to develop a brain-controlled exoskeleton that would allow a paralyzed person to walk onto the field and kick a soccer ball at the opening ceremony of next year’s World Cup in Brazil.

He says the new findings could point the way to future therapies aimed at restoring movement or language after a stroke or other brain injury by using signals from a healthy part of the brian to retrain the injured area. Other researchers say it’s an interesting idea, but it’s a long way off.

But Nicolelis’s group is known for pushing the envelope. Previously, they have given monkeys an artificial sense of touch they can use to distinguish the “texture” of virtual objects. More recently, they gave rats the ability to detect normally invisible infrared light by wiring an infrared detector to a part of the brain that processes touch. All this work, Nicolelis says, is relevant to developing neural prostheses to restore sensory feedback to people with brain injuries.

In the new study, the researchers implanted small electrode arrays in two regions of the rats’ brains, one involved in planning movements, and one involved in the sense of touch.

Then they trained several rats to poke their noses and whiskers through a small opening in the wall of their enclosure to determine its width. The scientists randomly changed the width of the opening to be either narrow or wide for each trial, and the rats had to learn to touch one of two spots depending on its width. They touched a spot to the right of the opening when it was wide and the spot on the left when it was narrow. When they got it correct, they received a drink. Eventually they got it right 95 percent of the time.

Next, the team wanted to see if signals from the brain of a rat trained to do this task could help another rat in a different cage choose the correct spot to poke with its nose — even if it had no other information to go on.

They tested this idea with another group of rats that hadn’t learned the task. In this experiment, one of these new rats sat in an enclosure with two potential spots to receive a reward but without an opening in the wall. On their own, they could only guess which of the two spots would produce a rewarding drink. As expected, they got it right 50 percent of the time.

Then the researchers recorded signals from one of the trained rats as it did the nose-poke task and used those signals to stimulate the second, untrained rat’s brain in a similar pattern. When it received this stimulation, the second rat’s performance climbed to 60 or 70 percent. That’s not nearly as good as the rats who could actually use their sense of touch to solve the problem, but it’s impressive given that the only information they had about which spot to chose came from another animal’s brain, Nicolelis says.

Both rats had to make the correct choice, otherwise neither one got a reward. When that happened, the first rat tended to make its decision more quickly on the next trial, and its brain activity seemed to send a clearer signal to the second rat, the team reports today in Scientific Reports. That suggests to Nicolelis that the rats were learning to cooperate.

The brain-to-brain communication link enables the rats to collaborate in a novel way, he says. ”The animals compute by mutual experience,” he said. ”It’s a computer that evolves, that’s not set by instructions or an algorithm.”

From an engineering perspective, the work is a remarkable demonstration that animals can use brain-to-brain communication to solve a problem, said Mitra Hartmann, a biomedical engineer who studies rats’ sense of touch at Northwestern University. “This is a first, to my knowledge, although the enabling technology has been around for a while.”

“From a scientific point of view, the study is noteworthy for the large number of important questions it raises, for example, what allows neurons to be so ‘plastic’ that the animal can learn to interpret the meaning of a particular stimulation pattern,” Hartmann said.

“It’s a pretty cool idea that they’re in tune with each other and working together,” said neuroscientist Bijan Pesaran of New York University. But Pesaran says he could use some more convincing that this is what’s actually going on. For example, he’d like to see the researchers extend the experiment to see if the rats on the receiving end of the brain-to-brain communication link could improve their performance even more. ”If you could see them learning to do it better and faster, then I’d really be impressed.”

Pesaran says he’s open to the idea that brain-to-brain communication could one day be used to rehabilitate brain injury patients, but he thinks it might be possible to accomplish the same thing by stimulating the injured brain with computer-generated patterns of activity. ”I don’t get why you’d need another brain to do that,” he said.

Phys Ed: What Housework Has to Do With Waistlines

Phys Ed

Gretchen Reynolds on the science of fitness.

One reason so many American women are overweight may be that we are vacuuming and doing laundry less often, according to a new study that, while scrupulously even-handed, is likely to stir controversy and emotions.

The study, published this month in PLoS One, is a follow-up to an influential 2011 report which used data from the U.S. Bureau of Labor Statistics to determine that, during the past 50 years, most American workers began sitting down on the job. Physical activity at work, such as walking or lifting, almost vanished, according to the data, with workers now spending most of their time seated before a computer or talking on the phone. Consequently, the authors found, the average American worker was burning almost 150 fewer calories daily at work than his or her employed parents had, a change that had materially contributed to the rise in obesity during the same time frame, especially among men, the authors concluded.

But that study, while fascinating, was narrow, focusing only on people with formal jobs. It overlooked a large segment of the population, namely a lot of women.

“Fifty years ago, a majority of women did not work outside of the home,” said Edward Archer, a research fellow with the Arnold School of Public Health at the University of South Carolina in Columbia, and lead author of the new study.

So, in collaboration with many of the authors of the earlier study of occupational physical activity, Dr. Archer set out to find data about how women had once spent their hours at home and whether and how their patterns of movement had changed over the years.

He found the information he needed in the American Heritage Time Use Study, a remarkable archive of “time-use diaries” provided by thousands of women beginning in 1965. Because Dr. Archer wished to examine how women in a variety of circumstances spent their time around the house, he gathered diaries from both working and non-employed women, starting with those in 1965 and extending through 2010.

He and his colleagues then pulled data from the diaries about how many hours the women were spending in various activities, how many calories they likely were expending in each of those tasks, and how the activities and associated energy expenditures changed over the years.

As it turned out, their findings broadly echoed those of the occupational time-use study. Women, they found, once had been quite physically active around the house, spending, in 1965, an average of 25.7 hours a week cleaning, cooking and doing laundry. Those activities, whatever their social freight, required the expenditure of considerable energy. (The authors did not include child care time in their calculations, since the women’s diary entries related to child care were inconsistent and often overlapped those of other activities.) In general at that time, working women devoted somewhat fewer hours to housework, while those not employed outside the home spent more.

Forty-five years later, in 2010, things had changed dramatically. By then, the time-use diaries showed, women were spending an average of 13.3 hours per week on housework.

More striking, the diary entries showed, women at home were now spending far more hours sitting in front of a screen. In 1965, women typically had spent about eight hours a week sitting and watching television. (Home computers weren’t invented yet.)

By 2010, those hours had more than doubled, to 16.5 hours per week. In essence, women had exchanged time spent in active pursuits, like vacuuming, for time spent being sedentary.

In the process, they had also greatly reduced the number of calories that they typically expended during their hours at home. According to the authors’ calculations, American women not employed outside the home were burning about 360 fewer calories every day in 2010 than they had in 1965, with working women burning about 132 fewer calories at home each day in 2010 than in 1965.

“Those are large reductions in energy expenditure,” Dr. Archer said, and would result, over the years, in significant weight gain without reductions in caloric intake.

What his study suggests, Dr. Archer continued, is that “we need to start finding ways to incorporate movement back into” the hours spent at home.

This does not mean, he said, that women — or men — should be doing more housework. For one thing, the effort involved is such activities today is less than it once was. Using modern, gliding vacuum cleaners is less taxing than struggling with the clunky, heavy machines once available, and thank goodness for that.

Nor is more time spent helping around the house a guarantee of more activity, over all. A telling 2012 study of television viewing habits found that when men increased the number of hours they spent on housework, they also greatly increased the hours they spent sitting in front of the TV, presumably because it was there and beckoning.

Instead, Dr. Archer said, we should start consciously tracking what we do when we are at home and try to reduce the amount of time spent sitting. “Walk to the mailbox,” he said. Chop vegetables in the kitchen. Play ball with your, or a neighbor’s, dog. Chivvy your spouse into helping you fold sheets. “The data clearly shows,” Dr. Archer said, that even at home, we need to be in motion.

DealBook: For S.E.C., a Setback in Bid for More Time in Fraud Cases

The Supreme Court on Wednesday delivered a swift and decisive rejection of the Securities and Exchange Commission’s argument that it should operate under a more forgiving statute of limitations in pursuing penalties in fraud cases.

As a result of the decision, the agency will have to find a long-term solution to give itself more time to investigate cases.

In Gabelli v. Securities and Exchange Commission, Chief Justice John G. Roberts Jr. wrote in the unanimous decision rejecting the S.E.C.’s argument that a federal statute that limits the government’s authority to pursue civil penalties should commence when a fraud is discovered, not when it occurred.

The S.E.C. was hoping that the court would apply what is known as the “discovery rule.” In 2010, the Supreme Court endorsed this rule in a private securities fraud class-action suit, Merck & Co. v. Reynolds, stating “that something different was needed in the case of fraud, where a defendant’s deceptive conduct may prevent a plaintiff from even knowing that he or she has been defrauded.”

The discovery rule is an exception to the protection afforded by a statute of limitations, which puts an endpoint on potential legal liability for conduct. Unlike most cases, when fraud is involved, it may not be apparent to the victims that they were harmed because the primary goal of deceptive conduct is to keep it from being exposed.

In the Gabelli case, the S.E.C. filed fraud charges in 2008 against the mutual fund manager Marc Gabelli and a colleague, Bruce Alpert, saying they had violated the Investment Advisers Act of 1940 for permitting an investor to engage in market timing. Ten years ago, a major scandal erupted when it came to light that some advisers had permitted select investors to buy shares at favorable prices to take advantage of pricing disparities in the securities held by mutual funds.

In its complaint, the S.E.C. sought civil monetary penalties based on market timing that it claimed had taken place from 1999 to 2002, and resulted in the preferred investor purportedly reaping significant profits while ordinary investors suffered large losses. The defendants denied the charges and filed a motion to dismiss the case because it was not brought in time.

A federal statute, 28 U.S.C. § 2462, provides that “an action, suit or proceeding for the enforcement of any civil fine, penalty, or forfeiture, pecuniary or otherwise, shall not be entertained unless commenced within five years from the date when the claim first accrued.” The provision dates to 1839, and applies to any government agency.

A decision by the United States Court of Appeals for the Second Circuit in Manhattan allowed the case to proceed by applying the discovery rule to a governmental action. Coincidentally, that decision was written by Judge Jed S. Rakoff, who despite being an occasional thorn in the S.E.C.’s side, accepted the agency’s argument to avoid a strict application of the five-year statute of limitations.

The Supreme Court, however, saw things differently. This week, it issued its opinion less than two months after it heard oral argument in the case in January, a clear sign the justices found no merit in the S.E.C.’s contention that the agency should be treated the same as private plaintiffs in trying to get around the statute of limitations.

According to the Supreme Court, victims in securities fraud cases should have a longer period to file a claim – from when the fraud was discovered. “Most of us do not live in a state of constant investigation,” the court wrote. “Absent any reason to think we have been injured, we do not typically spend our days looking for evidence that we were lied to or defrauded.”

Chief Justice Roberts explained that “the S.E.C. as enforcer is a far cry from the defrauded victim the discovery rule evolved to protect.” One of the reasons the agency exists is to detect and penalize violations, with tools that the ordinary investor simply does not have, like the authority to compel testimony and the production of documents. The message is simple. When it’s your job to investigate fraud, you cannot argue that your failure to do so is a justification for not meeting a statute of limitations.

The Supreme Court’s decision puts increased pressure on the S.E.C. to pursue its investigations with greater alacrity and not let them gather dust, which can occur as a result of staff turnover or other pressing issues. The market timing case is a good example of how an investigation might get lost in the shuffle as corporate accounting frauds at large companies like Enron and WorldCom, which also came to light in 2002, strained the S.E.C.’s investigative resources.

There are a couple of options to deal with this issue in the long run, apart from a substantial increase in the agency’s budget – an unlikely prospect in the face of the looming federal budget sequestration deadline.

The S.E.C. can obtain an agreement to stop the statute of limitations, known as tolling, from those it is investigating, something it has done in the past. For example, in its insider trading and securities fraud case against Samuel E. Wyly, his now deceased brother, Charles J. Wyly Jr., and two other defendants, the S.E.C. got an agreement that let it pursue claims beyond the normal five-year limitations period.

A permanent solution would be to seek legislation from Congress that would give the S.E.C. a longer window to complete its investigations. The statute of limitations is not a constitutional protection, so Congress can amend it as it sees fit, which it has done in other areas involving fraud.

The limitations period for banking crimes, for example, was extended to 10 years during the savings and loan crisis because of the crush of cases that made it difficult to finish investigations in the five-year window to initiate criminal prosecutions. The Fraud Enforcement and Recovery Act of 2009 added mail and wire fraud affecting a financial institution to the list of crimes that get the benefit of the 10-year limitations period, again because of fear that cases would be lost because of the number of investigations taking place after the financial crisis.

The issue of the statute of limitations may even come up at the confirmation hearings of Mary Jo White, who has been nominated to be chairwoman of the S.E.C. That could be an early indicator of whether she would be willing to push for relief from the effect of the Gabelli opinion to help out the enforcement division.

In the short run, the Supreme Court’s decision will cause defendants in government enforcement actions to examine whether they might be able to take advantage of the five-year limitations period. Given how slowly the government has been known to move on occasion, it may be that some cases will fall by the wayside because of the Gabelli decision.

Race for L.A. city controller heats up

A previously low-profile race for Los Angeles city controller has begun to heat up as opponents of City Councilman Dennis Zine accuse him of "double dipping" the city's payroll and question why he is considering lucrative tax breaks for a Warner Center developer.

Zine, who for 12 years has represented a district in the southeast San Fernando Valley, is the better known of the major candidates competing to replace outgoing Controller Wendy Greuel.

The others are Cary Brazeman, a marketing executive, and lawyer Ron Galperin. Zine has raised $766,000 for his campaign, more than double that of Galperin, the next-highest fundraiser, and has the backing of several of the city's powerful labor unions.

He also has been endorsed by Mayor Antonio Villaraigosa and several of his council colleagues. Galperin is backed by the Service Employees International Union, one the city's largest labor groups, and Brazeman is supported by retired Rep. Diane Watson and several neighborhood council representatives.

With the primary ballot less than a week away, Brazeman and Galperin have turned up the heat on Zine, hoping to push the race beyond the March 5 vote. If no one wins more than 50% of the ballots cast, the top two vote-getters will face a runoff in the May general election.

In a recent debate, Zine's opponents criticized him for receiving a $100,000 annual pension for his 33 years with the Los Angeles Police Department and a nearly $180,000 council salary. Brazeman and Galperin called it an example of "double dipping" that should be eliminated.

That brought a forceful response from Zine, who shot back that he gives a big portion of his police pension check to charities.

"I am so tired of hearing 'double dipping,' " he said. "I worked 33 years on the streets of Los Angeles. I have given over $300,000 to nonprofits that need it.... That's what's happened with that pension."

In the same debate, Brazeman accused Zine of cozying up to a Warner Center developer by pushing for tax breaks on a project that already has been approved. The nearly 30-acre Village at Westfield Topanga project would add 1 million square feet of new shops, restaurants, office space and a hotel to a faded commercial district on Topanga Canyon Boulevard.

"The councilman proposed to give developers at Warner Center tens of millions of dollars in tax breaks even though it's a highly successful project," he said. "He wants to give it away."

City records show that less than a month after the development was approved in February 2012, Zine asked the council for a study looking at possible "economic development incentives" that could be given to Westfield in return for speeding up street and landscaping enhancements to the project's exterior.

The motion's language notes that similar tax breaks have been awarded to large projects in the Hollywood and downtown areas, and that "similar public investment in the Valley has been lacking." Westfield is paying for the $200,000 study.

Zine defended his decision before the debate audience, saying if the study finds that the city will not benefit, no tax breaks will be awarded. "If there's nothing there, then they get nothing," Zine said.

The controller serves as a public watchdog over the city's $7.3-billion annual operation, auditing the general fund, 500 special fund accounts and the performance of city departments. Those audits often produce recommendations for reducing waste, fraud and abuse.

But the mayor and the council are not obligated to adopt those recommendations, and as a result the job is part accountant, part scolder in chief. All the candidates say they will use their elective position not only to perform audits but also to turn them into action.

Their challenge during the campaign has been explaining how they will do that.

Zine, 65, says his City Hall experience has taught him how to get things done by working with his colleagues. He won't be afraid to publicly criticize department managers, he said, but thinks collaboration works better than being combative.

"You can rant and rave and people won't work with you," he said. "Or you can sit down and talk it out, and you can accomplish things."

Galperin, 49, considers himself a policy wonk who relishes digging into the details to come up with ways to become more efficient with limited dollars and to find ways to raise revenue using the city's sprawling assets. For instance, the city owns two asphalt plants that could expand production and sell some of its material to raise money to fix potholes, he said.

He's served on two city commissions, including one that found millions of dollars in savings by detailing ways to be more efficient. Zine is positioning himself as a "tough guy for tough times," but the controller should be more than that, Galperin said.

"What we really need is some thoughtfulness and some smarts and some effectiveness," he said. "Just getting up there and saying we need to be tough is not going to accomplish what needs to be done."

Brazeman, 46, started his own marketing and public relations firm in West Los Angeles a decade ago and became active in city politics over his discontent with a development project near his home. He has pushed the council to change several initiatives over the last five years, including changes to the financing of the Farmers Field stadium proposal that will save taxpayer dollars, he said.

As controller, he would pick and choose his battles, and, Brazeman said, be "the right combination of constructive, abrasive and assertive."

Doctors Supercharge Their iPads With Box.net

Doctors love their iPads — even more than you might think.

Over in Winston-Salem, North Carolina, a group of more than 60 doctors have revamped their mobile phones and iPads for use in emergency departments across the region with a little help from a familiar application: the popular Box.net file-sharing services. Using Box, they’ve built a new system that lets them share procedures, journal articles and — perhaps most importantly — conversations.

It’s a small step, but doctors like Iltifat Husain at the Wake Forest Baptist Medical Center love the thing.

Husain is a big advocate of mobile devices. He edits a website for iPad-loving doctors called iMedicalApps.com. But the collaborative cloud computing thing really clicked for Husain — an emergency medicine resident physician at Wake Forest — when he was still testing the service back in October. He was at a remote emergency room in Greensboro, North Carolina, where a patient came in with fluid on the belly. Husain needed to perform a procedure called an abdominal paracentesis to drain the fluid. It’s not the kind of procedure that most doctors do every day, so Husain gave himself a quick refresher on the procedure.

A year earlier, this would have meant trudging over to the ER’s workstation and looking up a PDF on the hospital’s intranet. Instead, he tapped open the Box software on his mobile phone and looked it up right there.

It saved maybe a handful of minutes. But for Husain, minutes count. “In the ER, the faster I can do something, the more time I can spend with other patients,” he says.

Doctors may be the people who change our lives most profoundly with cutting-edge science and drugs, but the sad truth is that medicine is only just starting to enter the digital era, says Eric J.Topol, director of the Scripps Translational Science Institute and the author of, Creative Destruction of Medicine, a 2012 book about how digital technology is changing health care. “Medicine is ultra-conservative, historically.”

But it’s also an area that’s most primed for change. As the digital walls go down, doctors are becoming better about sharing information with their patients, and with other doctors.

Last year, a startup called Doximity launched a kind of social network for doctors — letting them share information, ask each other questions, and even provide referrals. It now has more than 100,000 doctors.

At Wake Forest, the Box set-up isn’t a full-fledged social network. It’s a document sharing workhorse. And with hundreds of journal articles and procedures — all uploaded, available via mobile phone and set up for comments — the system has in just a few short months become an important tool for the doctors who use it.

More than that, it’s also a great learning tool for residents, says James O’Neill, an M.D. and assistant professor with the hospital’s department of emergency medicine.

Online discussions have enhanced the residents monthly “Journal Club” meetings, where doctors meet do discuss the latest medical research. The system gives them an easy-to-use discussion platform where doctors and residents can debate what works and what does not work, direct from the emergency department. “When the residents find something that works for them, they can get it up there,” O’Neill says.

“We’ve been able to create this community in the cloud among residents,” says Husain. “You can literally have free flowing comments using Box, which really has the potential to change the way medical education is done.”

Topol says that this kind of social document sharing is only the beginning of a bigger shift that he’d like to see as the medical profession takes a cue from everyone else on the Internet and becomes better about collaborating and sharing information. “It’s a nice baby step, but it’s not a giant thing in the way that medicine is going to be shifting,” he says.

“We just have to take the walls down and we haven’t even started to do that yet.”
