Stem cell 'memory' can boost insulin levels
2011-07-14
Tel Aviv — Stem cells from early embryos can be coaxed into becoming a diverse array of specialized cells to revive and repair different areas of the body. Therapies based on these stem cells have long been contemplated for the treatment of diabetes, but have been held back by medical and ethical drawbacks.
Now researchers at Tel Aviv University are capitalizing on the "memories" of stem cells generated from adult cells to bring new hope to sufferers of juvenile or type 1 diabetes, which affects three million people in the United States.
Prof. Shimon Efrat of TAU's ...

The discovery gives hope to the world's most elusive big cat, which calls home to some of the world's tallest mountains. Between 4,500 and 7,500 snow leopards remain in the wild scattered across a dozen countries in Central Asia.
The study, which appears in the June 29th issue of the Journal of Environmental Studies, ...
Study explains why men are at higher risk for stomach cancer
2011-07-14
CAMBRIDGE, Mass. — Several types of cancer, including stomach, liver and colon, are far more common in men than in women. Some scientists have theorized that differences in lifestyle, such as diet and smoking, may account for the discrepancy, but growing evidence suggests that the differences are rooted in basic biological differences between men and women.
Adding to that evidence, a new study from MIT shows that treating male mice with estrogen dramatically lowers their rates of stomach cancer — specifically, cancers caused by chronic infection by the bacterium Helicobacter ...
Bold new approach to wind 'farm' design may provide efficiency gains
2011-07-14
College Park, Md. (July 13, 2011) -- Conventional wisdom suggests that because we're approaching the theoretical limit on individual wind turbine efficiency, wind energy is now a mature technology. But California Institute of Technology researchers revisited some of the fundamental assumptions that guided the wind industry for the past 30 years, and now believe that a new approach to wind farm design—one that places wind turbines close together instead of far apart—may provide significant efficiency gains.
This challenges the school of thought that the only remaining ...
25 Tesla, world-record 'split magnet' makes its debut
2011-07-14
A custom-built, $2.5 million "split magnet" system with the potential to revolutionize scientific research in a variety of fields has made its debut at the National High Magnetic Field Laboratory at Florida State University.
The world-record magnet is operating at 25 tesla, easily besting the 17.5 tesla French record set in 1991 for this type of magnet. ("Tesla," named for early 20th-century inventor and engineer Nikola Tesla, is a measurement of the strength of a magnetic field.) In addition to being 43 percent more powerful than the previous world best, the new magnet ...
UC Irvine study points to new approach to influenza's antiviral resistance
2011-07-14
Researchers from the University of California, Irvine, with assistance from the San Diego Supercomputer Center at UC San Diego, have found a new approach to the creation of customized therapies for virulent flu strains that resist current antiviral drugs.
The findings, published online this week in Nature Communications, could aid development of new drugs that exploit so-called flu protein 'pockets.'
Using powerful computer simulations on SDSC's new Trestles system, launched earlier this year under a $2.8 million National Science Foundation (NSF) award, UCI's Rommie ...

When well-known flu strains 'hook up' dangerous progeny can result
2011-07-14
COLLEGE PARK, Md. -- A new University of Maryland-led study finds that 'sex' between the virus responsible for the 2009 flu pandemic (H1N1) and a common type of avian flu virus (H9N2) can produce offspring -- new combined flu viruses -- with the potential for creating a new influenza pandemic.
Of course, viruses don't actually have sex, but University of Maryland virologist Daniel Perez, who directed the new study, says new pandemic viruses are formed mainly through a process called reassortment, which can best be described as viral sexual reproduction. "In reassortment, ...
Number of Mexican immigrants returning home dropped during latest recession, study finds
2011-07-14
Fewer Mexican immigrants returned home from the United States during 2008 and 2009 than in the two years prior to the start of the recession, a finding that contradicts the notion that the economic downturn has hastened return migration to Mexico, according to a new RAND Corporation study.
The study, published online by the journal Demography, is the first to track return migration trends by analyzing household survey information routinely collected by the Mexican government.
"The recession in the United States and the global financial crisis did not increase the number ...

Stem cells restore cognitive abilities impaired by brain cancer treatment
2011-07-14
Irvine, Calif., July 13, 2011 — Human neural stem cells are capable of helping people regain learning and memory abilities lost due to radiation treatment for brain tumors, a UC Irvine study suggests.
Research with rats found that stem cells transplanted two days after cranial irradiation restored cognitive function, as measured in one- and four-month assessments. In contrast, irradiated rats not treated with stem cells showed no cognitive improvement.
"Our findings provide solid evidence that such cells can be used to reverse radiation-induced damage of healthy tissue ...
Atomic structure discovered for a sodium channel that generates electrical signals in living cells
2011-07-14
Scientists at the University of Washington (UW) in Seattle have determined the atomic architecture of a sodium channel. The achievement opens new possibilities for molecular medicine researchers around the world in designing better drugs for pain, epilepsy, and heart rhythm disturbances.
Sodium channels are pores in the membranes of excitable cells – such as brain nerve cells or beating heart cells – that emit electrical signals. Sodium channels selectively open and close to allow the passage of millions of tiny charged particles across the cell membrane. The gated flow ...

Climate adaptation of rice
2011-07-14
Seattle – Rice – which provides nearly half the daily calories for the world's population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, just-published U.S. Geological Survey-led research shows.
In an effort to explore ways to increase the adaptability of rice to climatic scourges such as tsunamis and tidal surges that have already led to rice shortages, USGS researchers and their colleagues colonized two commercial varieties of rice with the spores of fungi that ...

Do women have what it takes?
2011-07-14
EVANSTON, Ill. --- So much has changed since 1963, when Betty Friedan's influential "The Feminine Mystique" provoked a national discussion about the deep dissatisfaction women were feeling about the limitations of their lives. Many women came to believe that discrimination limited their opportunities, especially in relation to leadership roles.
But a new Northwestern University meta-analysis (an integration of a large number of studies addressing the same question) shows that even today leadership continues to be viewed as culturally masculine. Thus, women suffer from ...
Breast Sagging: Causes and Remedies
2011-07-14
Surveys show that about 70% of women are unhappy with their breasts, and with age it is increasingly sagging that makes them unhappy. There are many myths surrounding breast sagging, but what really causes breasts to sag? And once they have begun to sag, how can you combat sagging?
Causes of Breast Sagging
The main cause of breast sagging is just gravity, the most implacable force in the universe. Over time, gravity stretches out breast tissue. However, the speed at which your breasts sag can be increased by:

Determining Liability in a Car Accident
2011-07-14
If you have been hurt in a car accident, you may want to file a lawsuit against the other driver and his insurance company. In order to win a personal injury case, you must prove the other drive was at fault, or liable, for your injuries. If a loved one has died due to someone else's reckless driving, you will have to prove the other driver was responsible for your loved one's death.
Proving Fault in a Car Accident
In its purest form, fault for causing an accident is either created by statute or defined by common law. Common law recognizes four basic levels of fault:

Narrowest bridges of gold are also the strongest, study finds
2011-07-14
BUFFALO, N.Y. -- At an atomic scale, the tiniest bridge of gold -- that made of a single atom -- is actually the strongest, according to new research by engineers at the University at Buffalo's Laboratory for Quantum Devices.
The counterintuitive finding is the result of experiments probing the characteristics of atomic-scale necks of gold that formed when the pointed, gold tip of a cantilever was pushed into a flat, gold surface. An examination of these tiny, gold bridges revealed that they were stiffest when they comprised just a single atom.
The study was published ...
Common Injuries from Motorcycle Accidents
2011-07-14
According to the National Highway Traffic Safety Administration (NHTSA), motorcyclists should wear helmets and protective clothing whenever operating their bikes. Motorcycles require more skill and attention to drive than passenger vehicles, which is why the NHTSA also recommends bikers take special courses to learn defensive driving and proper operation of their vehicles.
However, even the safest biker cannot always avoid a motorcycle accident, and despite protective clothing and helmets, bikers run a much higher risk of sustaining serious injury in an accident. When ...

Hip Fractures Among the Elderly
2011-07-14
Health issues intensify when an elderly person fractures a hip. In fact, 29 percent of older people who break a hip will die within one year; that's according to the University of Maryland School of Medicine. Combine a hip fracture with another chronic disease and morbidity can rise to 75 percent of those cases.
Unfortunately, hip fractures are on the rise. Approximately 300,000 Americans over the age of 64 break their hips annually. And, The large majority of those are women. Considering that millions of boomers will hit retirement age over the next few years, fractures ...
