Boeing 787 Completes Test Flight

A Boeing 787 test plane flew for more than two hours on Saturday to gather information about the problems with the batteries that led to a worldwide grounding of the new jets more than three weeks ago.

The flight was the first since the Federal Aviation Administration gave Boeing permission on Thursday to conduct in-flight tests. Federal investigators and the company are trying to determine what caused one of the new lithium-ion batteries to catch fire and how to fix the problems.

The plane took off from Boeing Field in Seattle heading mostly east and then looped around to the south before flying back past the airport to the west. It covered about 900 miles and landed at 2:51 p.m. Pacific time.

Marc R. Birtel, a Boeing spokesman, said the flight was conducted to monitor the performance of the plane’s batteries. He said the crew, which included 13 pilots and test personnel, said the flight was uneventful.

He said special equipment let the crew check status messages involving the batteries and their chargers, as well as data about battery temperature and voltage.

FlightAware, an aviation data provider, said the jet reached 36,000 feet. Its speed ranged from 435 to 626 miles per hour.

All 50 of the 787s delivered so far were grounded after a battery on one of the jets caught fire at a Boston airport on Jan. 7 and another made an emergency landing in Japan with smoke coming from the battery.

The new 787s are the most technically advanced commercial airplanes, and Boeing has a lot riding on their success. Half of the planes’ structural parts are made of lightweight carbon composites to save fuel.

Boeing also decided to switch from conventional nickel cadmium batteries to the lighter lithium-ion ones. But they are more volatile, and federal investigators said Thursday that Boeing had underestimated the risks.

The F.A.A. has set strict operating conditions on the test flights. The flights are expected to resume early this week, Mr. Birtel said.

Battery experts have said it could take weeks for Boeing to fix the problems.

A delicate new balancing act in senior healthcare

When Claire Gordon arrived at Cedars-Sinai Medical Center, nurses knew she needed extra attention.

She was 96, had heart disease and a history of falls. Now she had pneumonia and the flu. A team of Cedars specialists converged on her case to ensure that a bad situation did not turn worse and that she didn't end up with a lengthy, costly hospital stay.

Frail seniors like Gordon account for a disproportionate share of healthcare expenditures because they are frequently hospitalized and often land in intensive care units or are readmitted soon after being released. Now the federal health reform law is driving sweeping changes in how hospitals treat a rapidly growing number of elderly patients.

The U.S. population is aging quickly: People older than 65 are expected to make up nearly 20% of it by 2030. Linda P. Fried, dean of the Columbia University Mailman School of Public Health, said now is the time to train professionals and test efforts to improve care and lower healthcare costs for elderly patients.

"It's incredibly important that we prepare for being in a society where there are a lot of older people," she said. "We have to do this type of experiment right now."

At Cedars-Sinai, where more than half the patients in the medical and surgical wards are 65 or older, one such effort is dubbed the "frailty project." Within 24 hours, nurses assess elderly patients for their risk of complications such as falls, bed sores and delirium. Then a nurse, social worker, pharmacist and physician assess the most vulnerable patients and make an action plan to help them.

The Cedars project stands out nationally because medical professionals are working together to identify high-risk patients at the front end of their hospitalizations to prevent problems at the back end, said Herb Schultz, regional director of the U.S. Department of Health and Human Services.

"For seniors, it is better care, it is high-quality care and it is peace of mind," he said.

The effort and others like it also have the potential to reduce healthcare costs by cutting preventable medical errors and readmissions, Schultz said. The federal law penalizes hospitals for both.

Gordon, an articulate woman with brightly painted fingernails and a sense of humor, arrived at Cedars-Sinai by ambulance on a Monday.

Soon, nurse Jacquelyn Maxton was at her bedside asking a series of questions to check for problems with sleep, diet and confusion. The answers led to Gordon's designation as a frail patient. The next day, the project team huddled down the hall and addressed her risks one by one. Medical staff would treat the flu and pneumonia while at the same time addressing underlying health issues that could extend Gordon's stay and slow her recovery, both in the hospital and after going home.

To reduce the chance of falls, nurses placed a yellow band on her wrist that read "fall risk" and ensured that she didn't get up on her own. To prevent bed sores, they got her up and moving as often as possible. To cut down on confusion, they reminded Gordon frequently where she was and made sure she got uninterrupted sleep. Medical staff also stopped a few unnecessary medications that Gordon had been prescribed before her admission, including a heavy narcotic and a sleeping pill.

"It is really a holistic approach to the patient, not just to the disease that they are in here for," said Glenn D. Braunstein, the hospital's vice president for clinical innovation.

Previously, nurse Ivy Dimalanta said, she and her colleagues provided similar care but on a much more random basis. Under the project, the care has become standardized.

The healthcare system has not been well designed to address the needs of seniors who may have had a lifetime of health problems, said Mary Naylor, gerontology professor at the University of Pennsylvania School of Nursing. As a result, patients sometimes fall through the cracks and return to hospitals again and again.

"That is not good for them and that is not good for society to be using resources in that way," Naylor said.

Using data from related projects, Cedars began a pilot program in 2011 and expanded it last summer. The research is continuing but early results suggest that the interventions are leading to fewer seniors being admitted to the intensive care unit and to shorter hospital stays, said Jeff Borenstein, researcher and lead clinician on the frailty project. "It definitely seems to be going in the right direction," he said.

The hospital is now working with Naylor and the University of Pennsylvania to design a program to help the patients once they go home.

"People who are frail are very vulnerable when they leave the hospital," said Harriet Udin Aronow, a researcher at Cedars. "We want to promote them being safe at home and continuing to recover."

In Gordon's case, she lives alone with the help of her children and a caregiver. The hospital didn't want her experiencing complications that would lengthen the stay, but they also didn't want to discharge her before she was ready. Under the health reform law, hospitals face penalties if patients come back too soon after being released.

Patients and their families often are unaware of the additional attention. Sitting in a chair in front of a vase of pink flowers, Gordon said she knew she would have to do her part to get out of the hospital quickly. "You have to move," she said. "I know you get bed sores if you stay in bed."

Gordon said she was comfortable at the hospital but she wanted to go back to her house as quickly as she could. "There's no place like home," she said.

Two days later, that's where she was.

Fate of Historic Landsat Mission Hinges on Upcoming Launch

Since 1972 the Landsat mission has been monitoring natural and human-made changes to our planet. But the continuity of that scientifically precious dataset could be lost unless all goes according to plan on Monday, when the Landsat 8 satellite is scheduled to be launched into orbit from Vandenberg Air Force Base in California. Landsat 8 will take over for the hobbled 14-year old Landsat 7 that has been valiantly carrying the mission alone since December when, after 29 years in orbit, Landsat 5 began to be decommissioned after a gyroscope failure.

The launch is not likely to fail, but if it does, it won’t be the first time the continuity of the 40-year mission was jeopardized. Along the way funding has come under fire, ownership of the satellites has been transferred between government agencies and private companies, sensors have quit working, and one mission tragically failed to reach orbit. If Landsat 8 fails, Landsat 7 would run out of fuel near the end of 2016, before a replacement could be built and put into orbit.

“I’ve devoted the latter part of my career to the formulation and development of this mission,” the project’s lead scientist, James Irons, told Wired. “On Monday I go out there and look at my baby sitting on top of an enormous firecracker and hope everything goes well.”

“Yeah, I’ll be nervous.”

The scientists and engineers behind the Landsat mission will be hugely relieved once the craft is safely in place 700 kilometers above their heads and then begins beaming data back to Earth about a month later.

In addition to saving the mission from a gap in data, Landsat 8 — more officially known as the Landsat Data Continuity Mission – will boost the rate of coverage of the Earth and will also add more sensing capability and deliver better imagery than its predecessors.

Relying on Landsat 7 alone has meant only imaging the full Earth every 16 days. Once there are two eyes open, coverage will return to 8-day intervals, essentially doubling the resolution of landscape change that will be recorded.

“The major goal of the mission is for us to understand land cover and land use change, and determine the human impacts on the global landscape,” Irons said. “These changes are going on at rates unprecedented in human history.”

“Continuity is more important than ever.”

The new satellite will also add more sensing capability and deliver better imagery than its predecessors. Landsat 8 will measure all the spectral bands of its predecessors, but will add two new bands that are tailored for detecting the coastal zone and cirrus clouds.

The new satellite has a more advanced imaging design as well. Previous Landsat satellites used what is known as a whisk broom sensor system, where an oscillating mirror would sweep back and forth over a row of detectors that collect data across a 185-kilometer swath of the Earth. The new push system uses a very long array of more than 7,000 detectors that will view the 185 km swath simultaneously, alternately collecting light and recording data. This allows each detector to dwell on each pixel for a longer time, resulting in more detailed, accurate descriptions of the landscape.

Once Landsat 8 reaches orbit, the engineers will begin testing the spacecraft during the first week. The next few weeks will be dedicated to testing all the instruments. The satellite will then do a cross-over rendezvous with Landsat 7 to calibrate the two systems. Around day 25, the shutters will be opened and Landsat 8 will take its first look at Earth. By the end of May, the data should be flowing. The new satellite has a design life of five years, but it has enough fuel to operate for 10 years.

But first, the new craft has to get safely into orbit.

“I have a lot of assurance from everyone,” Irons said. “They are taking extraordinary care, proceeding very methodically, cautiously and rigorously.”

“Still, you realize all rocket launches have some inherent risk,” he said. “So, it’s just hold your breath and hope everything goes well.”

Recovering ‘Good Morning America’ host Robin Roberts sets return

(Reuters) – “Good Morning America” host Robin Roberts will rejoin the ABC morning television show on February 20 after treatment for a rare blood disorder, the show said on Thursday.

Roberts’ doctors deemed her healthy enough to return to work five months after receiving a bone marrow transplant to treat myelodysplastic syndrome, a bone marrow disorder triggered by treatment for breast cancer five years ago.

“I’m excited to rejoin my wonderful ‘GMA’ family,” Roberts, 52, said in a note posted online on Thursday. “I’m also looking forward to thanking YOU … for your many prayers and well wishes. Your compassion has been an enormous source of comfort to me and my family.”

Roberts will begin appearing on an abbreviated schedule and eventually return to working five days a week, co-anchor Sam Champion said on the show.

Roberts revealed her illness in June and started medical leave in August.

In Nigeria, Polio Vaccine Workers Are Killed by Gunmen

At least nine polio immunization workers were shot to death in northern Nigeria on Friday by gunmen who attacked two clinics, officials said.

The killings, with eerie echoes of attacks that killed nine female polio workers in Pakistan in December, represented another serious setback for the global effort to eradicate polio.

Most of the victims were women and were shot in the back of the head, local reports said.

A four-day vaccination drive had just ended in Kano State, where the killings took place, and the vaccinators were in a “mop-up” phase, looking for children who had been missed, said Sarah Crowe, a spokeswoman for the United Nations Children’s Fund, one of the agencies running the eradication campaign.

Dr. Mohammad Ali Pate, Nigeria’s minister of state for health, said in a telephone interview that it was not entirely clear whether the gunmen were specifically targeting polio workers or just attacking the health centers where vaccinators happened to be gathering early in the morning. “Health workers are soft targets,” he said.

No one immediately took responsibility, but suspicion fell on Boko Haram, a militant Islamist group that has attacked police stations, government offices and even a religious leader’s convoy.

Polio, which once paralyzed millions of children, is now down to fewer than 1,000 known cases around the world, and is endemic in only three countries: Nigeria, Pakistan and Afghanistan.

Since September — when a new polio operations center was opened in the capital and Nigeria’s president, Goodluck Jonathan, appointed a special adviser for polio — the country had been improving, said Dr. Bruce Aylward, chief of polio eradication for the World Health Organization. There have been no new cases since Dec. 3.

While vaccinators have not previously been killed in the country, there is a long history of Nigerian Muslims shunning the vaccine.

Ten years ago, immunization was suspended for 11 months as local governors waited for local scientists to investigate rumors that it caused AIDS or was a Western plot to sterilize Muslim girls. That hiatus let cases spread across Africa. The Nigerian strain of the virus even reached Saudi Arabia when a Nigerian child living in hills outside Mecca was paralyzed.

Heidi Larson, an anthropologist at the London School of Hygiene and Tropical Medicine who tracks vaccine issues, said the newest killings “are kind of mimicking what’s going on in Pakistan, and I feel it’s very much prompted by that.”

In a roundabout way, the C.I.A. has been blamed for the Pakistan killings. In its effort to track Osama bin Laden, the agency paid a Pakistani doctor to seek entry to Bin Laden’s compound on the pretext of vaccinating the children — presumably to get DNA samples as evidence that it was the right family. That enraged some Taliban factions in Pakistan, which outlawed vaccination in their areas and threatened vaccinators.

Nigerian police officials said the first shootings were of eight workers early in the morning at a clinic in the Tarauni neighborhood of Kano, the state capital; two or three died. A survivor said the two gunmen then set fire to a curtain, locked the doors and left.

“We summoned our courage and broke the door because we realized they wanted to burn us alive,” the survivor said from her bed at Aminu Kano Teaching Hospital.

About an hour later, six men on three-wheeled motorcycles stormed a clinic in the Haye neighborhood, a few miles away. They killed seven women waiting to collect vaccine.

Ten years ago, Dr. Larson said, she joined a door-to-door vaccination drive in northern Nigeria as a Unicef communications officer, “and even then we were trying to calm rumors that the C.I.A. was involved,” she said. The Iraq and Afghanistan wars had convinced poor Muslims in many countries that Americans hated them, and some believed the American-made vaccine was a plot by Western drug companies and intelligence agencies.

Since the vaccine ruse in Pakistan, she said, “Frankly, now, I can’t go to them and say, ‘The C.I.A. isn’t involved.’ ”

Dr. Pate said the attack would not stop the newly reinvigorated eradication drive, adding, “This isn’t going to deter us from getting everyone vaccinated to save the lives of our children.”

Aminu Abubakar contributed reported from Kano, Nigeria.

John E. Karlin, 1918-2013: John E. Karlin, Who Led the Way to All-Digit Dialing, Dies at 94

Courtesy of Alcatel-Lucent USA

John E. Karlin, a researcher at Bell Labs, studied ways to make the telephone easier to use.

A generation ago, when the poetry of PEnnsylvania and BUtterfield was about to give way to telephone numbers in unpoetic strings, a critical question arose: Would people be able to remember all seven digits long enough to dial them?

And when, not long afterward, the dial gave way to push buttons, new questions arose: round buttons, or square? How big should they be? Most crucially, how should they be arrayed? In a circle? A rectangle? An arc?

For decades after World War II, these questions were studied by a group of social scientists and engineers in New Jersey led by one man, a Bell Labs industrial psychologist named John E. Karlin.

By all accounts a modest man despite his variegated accomplishments (he had a doctorate in mathematical psychology, was trained in electrical engineering and had been a professional violinist), Mr. Karlin, who died on Jan. 28, at 94, was virtually unknown to the general public.

But his research, along with that of his subordinates, quietly yet emphatically defined the experience of using the telephone in the mid-20th century and afterward, from ushering in all-digit dialing to casting the shape of the keypad on touch-tone phones. And that keypad, in turn, would inform the design of a spate of other everyday objects.

It is not so much that Mr. Karlin trained midcentury Americans how to use the telephone. It is, rather, that by studying the psychological capabilities and limitations of ordinary people, he trained the telephone, then a rapidly proliferating but still fairly novel technology, to assume optimal form for use by midcentury Americans.

“He was the one who introduced the notion that behavioral sciences could answer some questions about telephone design,” Ed Israelski, an engineer who worked under Mr. Karlin at Bell Labs in the 1970s, said in a telephone interview on Wednesday.

In 2013, the 50th anniversary of the introduction of the touch-tone phone, the answers to those questions remain palpable at the press of a button. The rectangular design of the keypad, the shape of its buttons and the position of the numbers — with “1-2-3” on the top row instead of the bottom, as on a calculator — all sprang from empirical research conducted or overseen by Mr. Karlin.

The legacy of that research now extends far beyond the telephone: the keypad design Mr. Karlin shepherded into being has become the international standard on objects as diverse as A.T.M.’s, gas pumps, door locks, vending machines and medical equipment.

Mr. Karlin, associated from 1945 until his retirement in 1977 with Bell Labs, headquartered in Murray Hill, N.J., was widely considered the father of human-factors engineering in American industry.

A branch of industrial psychology that combines experimentation, engineering and product design, human-factors engineering is concerned with easing the awkward, often ill-considered marriage between man and machine. In seeking to design and improve technology based on what its users are mentally capable of, the discipline is the cognitive counterpart of ergonomics.

“Human-factors studies are different from market research and other kinds of studies in that we observe people’s behavior and record it, systematically and without bias,” Mr. Israelski said. “The hallmark of human-factors studies is they involve the actual observation of people doing things.”

Among the issues Mr. Karlin examined as the head of Bell Labs’ Human Factors Engineering department — the first department of its kind at an American company — were the optimal length for a phone cord (a study that involved gentle, successful sabotage) and the means by which rotary calls could be made efficiently after the numbers were moved from inside the finger holes, where they had nestled companionably for years, to the rim outside the dial.

John Elias Karlin was born in Johannesburg on Feb. 28, 1918, and reared nearby in Germiston, where his parents owned a grocery store and tearoom.

He earned a bachelor’s degree in philosophy, psychology and music, and a master’s degree in psychology, both from the University of Cape Town. Throughout his studies he was a violinist in the Cape Town Symphony Orchestra and the Cape Town String Quartet.

Moving to the United States, Mr. Karlin earned a Ph.D. from the University of Chicago in 1942. Afterward, he became a research associate at Harvard; he also studied electrical engineering there and at the Massachusetts Institute of Technology.

At Harvard, Mr. Karlin did research for the United States military on problems in psychoacoustics that were vital to the war effort — studying the ways, for instance, in which a bomber’s engine noise might distract its crew from their duties.

Big Bear locked down amid manhunt

The bustling winter resort of Big Bear took on the appearance of a ghost town Thursday as surveillance aircraft buzzed overhead and police in tactical gear and carrying rifles patrolled mountain roads in convoys of SUVs, while others stood guard along major intersections.

Even before authorities had confirmed that the torched pickup truck discovered on a quiet forest road belonged to suspected gunman Christopher Dorner, 33, officials had ordered an emergency lockdown of local businesses, homes and the town's popular ski resorts. Parents were told to pick up their children from school, as rolling yellow buses might pose a target to an unpredictable fugitive on the run.

By nightfall, many residents had barricaded their doors as they prepared for a long, anxious evening.

PHOTOS: A tense manhunt amid tragic deaths

"We're all just stressed," said Andrea Burtons as she stocked up on provisions at a convenience store. "I have to go pick up my brother and get him home where we're safe."

Police ordered the lockdown about 9:30 a.m. as authorities throughout Southern California launched an immense manhunt for the former lawman, who is accused of killing three people as part of a long-standing grudge against the LAPD. Dorner is believed to have penned a long, angry manifesto on Facebook saying that he was unfairly fired from the force and was now seeking vengeance.

Forest lands surrounding Big Bear Lake are cross-hatched with fire roads and trails leading in all directions, and the snow-capped mountains can provide both cover and extreme challenges to a fugitive on foot. It was unclear whether Dorner was prepared for such rugged terrain.

Footprints were found leading from Dorner's burned pickup truck into the snow off Forest Road 2N10 and Club View Drive in Big Bear Lake.

San Bernardino County Sheriff John McMahon said that although authorities had deployed 125 officers for tracking and door-to-door searches, officers had to be mindful that the suspect may have set a trap.

"Certainly. There's always that concern and we're extremely careful and we're worried about this individual," McMahon said. "We're taking every precaution we can."

PHOTOS: A fugitive's life on Facebook

Big Bear has roughly 400 homes, but authorities guessed that only 40% are occupied year-round.

The search will probably play out with the backdrop of a winter storm that is expected to hit the area after midnight.

Up to 6 inches of snow could blanket local mountains, the National Weather Service said.

Gusts up to 50 mph could hit the region, said National Weather Service meteorologist Mark Moede, creating a wind-chill factor of 15 to 20 degrees.

Extra patrols were brought in to check vehicles coming and going from Big Bear, McMahon said, but no vehicles had been reported stolen.

"He could be anywhere at this point," McMahon said. When asked if the burned truck was a possible diversion, McMahon replied: "Anything's possible."

Dorner had no known connection to the area, authorities said.

Craig and Christine Winnegar, of Murrieta, found themselves caught up in the lockdown by accident. Craig brought his wife to Big Bear as a surprise to celebrate their 28th wedding anniversary. Their prearranged dinner was canceled when restaurant owners closed their doors out of fear.

"It's definitely scary," Christine Winnegar said.

Apparent Facebook Widget Snafu Brings Down Sites

Several sites across the web could not be reached by some visitors on Thursday afternoon, apparently because of a problem with Facebook widgets embedded in the sites. Several sites — including Business Insider, Huffington Post and Salon — were reportedly affected, redirecting visitors to a Facebook error page.

Facebook did not immediately respond to a request for comment, but the problem has apparently been fixed. The problem was first reported by Marketing Land.

When trying to visit a page that used Facebook Connect or Like widgets, users were redirected to a page saying simply “An error occurred. Please try again later.” When they clicked the “Okay” button, they were taken to an error page. If they hit back, they would get to the page they were trying to visit momentarily before being automatically forwarded to the error page again.

Facebook provides code to embed widgets that display information such as which of your friends like a site’s Facebook page, or which articles have recently been “liked” by a friend. These widgets execute JavaScript code in the user’s web browser that originates at Facebook, not the site that the user is trying to view. The problem only seems to affect users who are not logged into Facebook.

Update: Facebook has now said: “For a short period of time, there was a bug that redirected people logging in with Facebook from third party sites to Facebook.com. The issue was quickly resolved, and Login with Facebook is now working as usual.”

Broadway Motown musical features civil rights, love story

NEW YORK (Reuters) – Motown founder Berry Gordy Jr. watched with approval on Thursday as the cast of upcoming Broadway show “Motown: The Musical” tore through the storied record label’s hits at a 42nd Street rehearsal studio.

The show traces Gordy’s rise from a struggling boxer and autoworker to a music mogul who made stars of Smokey Robinson, Diana Ross, The Temptations, Stevie Wonder, Marvin Gaye, The Jackson 5 and others.

“So many other people were telling the story in different ways who were never there and never understood it, just for the sake of exploitation,” Gordy, 83, a producer of the show, told Reuters.

The media preview featured hits ranging from The Contours’ “Do You Love Me” – sung as a segregated audience in Birmingham, Alabama, breaks through a rope to hear the group – to “Dancing in the Street” by Martha and the Vandellas.

Director Charles Randolph-Wright, who grew up in South Carolina in the 1960s, said Motown was in his DNA.

“Motown opened the emotional door to the civil rights movement,” he told Reuters. “Motown is the thing that brought people together. We started dancing to the same music and listening to the same music.”

Gordy’s relationship with Ross – the couple had a daughter together – is shown beginning in Paris, to the hit “My Girl” by The Temptations.

“That’s the love story in our show,” Randolph-Wright said.

The musical begins previews on March 11 and officially opens on April 14. It features a book by Gordy and music and lyrics from the Motown catalog.

Although the show is from Gordy’s perspective, it doesn’t duck some of the criticism that surrounded him, especially in Motown‘s early days, Randolph-Wright said.

As Gordy explained: “At one time, people were feeling that how could a black kid from Detroit do a Motown without being a crook, without being in the Mafia, without being something bad, because it was such a big endeavor.”

Gordy, the creator of what was once the largest black-owned business in the United States, was an inspiration to him, Randolph-Wright said.

“Berry Gordy was someone who had his own company, who literally changed the world with what he did,” he said. “And to see that, it gave me and so many people like me – black, white, whatever color – that gift of possibility.”

Brandon Victor Dixon, who plays Gordy, said it was “hard to have a greater honor than having Berry Gordy respect you as an artist.”

Valisia LeKae, who appeared in “The Book of Mormon,” plays Ross. “It is the soundtrack of people’s lives,” LeKae said of the music. “I definitely expect people to sing along.”

Well: Old Age and Motorcycles Are a Dangerous Mix

If you’re over 40 and planning to hop on a motorcycle, take care. Compared with younger riders, the odds of being seriously injured are high.

That is the message of a new study, published this week in the journal Injury Prevention, which found that older bikers are three times as likely to be severely injured in a crash as younger riders.

The percentage of older bikers on the road is quickly rising, and their involvement in accidents is a growing concern. Nationwide, from 1990 to 2003, the percentage of motorcyclists over age 50 soared from roughly 1 in 10 to about 1 in 4. At the same time, the average age of riders involved in motorcycle crashes has also been climbing. Injury rates among those 65 and older jumped 145 percent from 2000 to 2006 alone.

Because of the increase in motorcycle ridership among older Americans, the researchers, led by Tracy Jackson, a graduate student in the epidemiology department at Brown University, wanted a closer look at their injury patterns. So she and her colleagues combed through a federal database of motorcycle crashes that were serious enough to require emergency medical care. That yielded about 1.5 million incidents involving motorcyclists 20 or older from 2001 to 2008.

The researchers then split them into groups: those in their 20s and 30s, another group between 40 and 59, and those 60 and older.

Over all, the study showed that injury rates for all three groups were on the rise. But the rise was steepest for the oldest riders. Compared with the youngest motorcyclists, those who were 60 and older were two and a half times as likely to end up with serious injuries, and three times as likely to be admitted to a hospital. The riders who were middle age were twice as likely as their younger counterparts to be hospitalized.

For older riders, the consequences of a collision were also especially alarming. Older and middle-aged bikers were more likely to sustain fractures and dislocations, and they had a far greater chance of ending up with injuries to internal organs, including brain damage.

The researchers speculated that it was very likely that a number of factors played a role in older riders’ higher injury rates. For one, declines in vision and reaction time may make older riders more prone to mistakes that end up in collisions. Another theory is that older riders tend to ride bigger bikes, “which may be more likely to roll or turn over,” Ms. Jackson said.

Then there is the greater fragility that comes with age. Older riders may be involved in the same types of accidents as younger riders, Ms. Jackson said, but in some cases, a collision that a 20-year-old would walk away from might send a 65-year-old to the hospital.

“Your bones become more brittle, and you lose muscle mass as you get older,” she said. “It could just be a matter of aging and the body being less durable.”
