In-patient rehab recommended over nursing homes for stroke rehab

The American Heart Association/American Stroke Association has issued its first guidelines on adult stroke rehabilitation calling for intensive, multidisciplinary treatment. Before leaving the hospital, patients and caregivers should receive a formal falls-prevention program to prevent accidents at home. Whenever possible, initial rehabilitation should take place in an inpatient rehabilitation facility rather than a nursing home.

Best Treatment for Preschoolers with ADHD Is Not Meds, CDC Urges

Best Treatment for Preschoolers with ADHD Is Not Meds, CDC UrgesMany young children with attention deficit hyperactivity disorder (ADHD) aren't receiving the top recommended treatment for the condition, a new report suggests. The report, from the Centers for Disease Control and Prevention, looked at insurance claims for 5 million U.S. children, ages 2 to 5, who were all receiving treatment for ADHD. The researchers said they wanted to see how many of these children received behavioral therapy, now recommended as the first treatment to try for young kids who have the condition.

Deadly Mistakes: Medical Errors Are 3rd Leading Cause of Death

Deadly Mistakes: Medical Errors Are 3rd Leading Cause of DeathMedical errors may be the third leading cause of death in the United States, a new review suggests. The next most common cause of death after medical errors was chronic lower respiratory infection, which accounted for nearly 150,000 deaths that year, the researchers found. But because of how deaths are currently reported in the U.S., medical errors are rarely listed as the cause of death, said the review, published today (May 3) in the journal BMJ.

For first time, scientists grow two-week-old human embryos in lab

By Kate Kelland LONDON(Reuters) – Scientists have for the first time grown human embryos outside of the mother for almost two full weeks into development, giving unique insight into what they say is the most mysterious stage of early human life. Scientists had previously only been able to study human embryos as a culture in a lab dish until the seventh day of development when they had to implant them into the mother’s uterus to survive and develop further. “This it the most enigmatic and mysterious stage of human development,” said Magdalena Zernicka-Goetz, a University of Cambridge professor who co-led the work.

Major Depression Might Be Averted by Online Help: Study

People who may be sliding toward depression might be able to prevent the full-blown disorder by completing some self-help exercises online, a new study suggests. Researchers found that men and women who had some symptoms of depression and used a web-based mental health program that was supported by an online trainer were less likely to experience a major depressive episode during a 1-year follow-up period, compared with people who also had symptoms of depression but were only given online access to educational materials about the signs of depression and its treatment. The results of the study suggest that a web-based, guided self-help intervention could effectively reduce the risk of major depressive disorder or at least delay its onset, said lead study author Claudia Buntrock, a doctoral student in psychology at Leuphana University in Lueneburg, Germany.

Land titles for farmers help cut Brazil’s forest loss: scientist

By Chris Arsenault RIO DE JANEIRO (Thomson Reuters Foundation) – Brazil should speed up its program to grant small farmers formal land ownership to slow down the rate of logging and deforestation, a leading scientist said. Farmers on small holdings are responsible for about 30 percent of the logging and destruction of Brazil’s vast forests, up from about 23 percent 10 years ago, said Daniel Nepstad, executive director of the California-based Earth Innovation Institute. “A lack of clear land title pushes small farmers to opt for cattle (rearing) instead of more intensive (food) production” said Nepstad, a specialist with 30 years of experience tracking Amazon deforestation told the Thomson Reuters Foundation.

Scientists win $3 million for detecting Einstein’s waves

File photo of Dr. Thorne of Caltech listening during news conference on detection of gravitational waves, in WashingtonBy Joseph Ax NEW YORK (Reuters) – Researchers who helped detect gravitational waves for the first time, confirming part of Albert Einstein's theory in a landmark moment in scientific history, will share a $3 million Special Breakthrough Prize, according to the prize's selection committee. The Breakthrough Prizes for scientific achievements were created by Russian billionaire Yuri Milner along with several technology pioneers, including Facebook founder Mark Zuckerberg and Google co-founder Sergey Brin. In February, a team from the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced a pair of giant laser detectors had measured the tiny ripples in space and time first theorized by Einstein a century ago, capping a decades-long quest.

Solar-powered plane lands in Arizona on round-the-world flight

Pilots Borschberg and Piccard react after landing Solar Impulse 2 on the San Francisco to Phoenix leg of what they hope will be the first round-the-world solar-powered flight, in PhoenixBy Steve Gorman LOS ANGELES (Reuters) – A solar-powered airplane midway through a historic bid to circle the globe completed the 10th leg of its journey on Monday, landing in Arizona after a 16-hour flight from California, the project team said. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived in Phoenix shortly before 9 p.m., following a flight from San Francisco that took it over the Mojave Desert.

Newly discovered planets may boost search for life beyond Earth

Handout of an artist's impression of the ultracool dwarf star TRAPPIST-1 and its three planetsBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – The discovery of three planets that circle a small, dim star could bolster the chances of finding life beyond Earth, astronomers said on Monday. The Earth-sized planets are orbiting their parent star, located in the constellation Aquarius relatively close to Earth at 40 light years away, at a distance that provides the right amount of heat for there to be liquid water on their surface, a condition scientists believe may be critical for fostering life. The discovery marked the first time that planets were found orbiting a common type of star known as an ultra-cool dwarf, the scientists said.
