Gastric bypass surgery helps diabetes but doesn't cure it
After gastric bypass surgery, diabetes goes away for some people -- often even before they lose much weight. So does that mean gastric surgery "cures" diabetes? Not necessarily, according to the largest community-based study of long-term diabetes outcomes after bariatric surgery. For most people in the multi-site HMO Research Network study, e-published in advance of print in Obesity Surgery, diabetes either never remitted after gastric surgery or relapsed within five years.

Alaska's iconic Columbia Glacier expected to stop retreating in 2020, says CU-Boulder study
The wild and dramatic cascade of ice into the ocean from Alaska's Columbia Glacier, an iconic glacier featured in the documentary "Chasing Ice" and one of the fastest moving glaciers in the world, will cease around 2020, according to a study by the University of Colorado Boulder.

Algae Biomass Organization hails new UCSD study showing saltwater algae viable for biofuels
The Algae Biomass Organization, the trade association for the US algae industry today hailed the findings of a University of California at San Diego study that concludes, for the first time, that marine (saltwater) algae can be just as capable as freshwater algae in producing biofuels. The research is documented in a peer-reviewed paper published online in the current issue of the scientific journal Algal Research.

University of Maryland School of Medicine, NIH study pinpoints brain area's role in learning
An area of the brain called the orbitofrontal cortex is responsible for decisions made on the spur of the moment, but not those made based on prior experience or habit, according to a new study in Science from substance abuse researchers at the University of Maryland School of Medicine and the National Institute on Drug Abuse. The distinction is critical to understanding the neurobiology of decision-making, particularly with regard to substance abuse.

Dramatic rise in autism prevalence parallels research explosion
Autism Speaks Chief Science Officer Geraldine Dawson, Ph.D., describes the dramatic progress in autism research paralleling increased recognition of autism's prevalence and financial impact in the Archives of General Psychiatry. She notes funding for autism research hasn't kept pace with the increasing scale of the public health challenges posed by autism and more research is needed on prenatal and early postnatal brain development, on gene and environmental risk factors, treatment and adults with autism.

Possible new treatment for Ewing sarcoma
Discovery of a new drug with high potential to treat Ewing sarcoma, an often deadly cancer of children and young adults, and the previously unknown mechanism behind it, come hand-in-hand in a new study by researchers from Huntsman Cancer Institute at the University of Utah. The report appears in today's online issue of the journal Oncogene.

Students at cooperative schools are more engaged
Student engagement is not independent of the type of school attended.Nor is it independent of the organizational development of the school. The school's organizational style affects the work of its teaching staff, which, in turn, has repercussions on the performance and engagement of their students. As IkerRos, the UPV/EHU researcher, has been able to verify in his PhD thesis, these factors vary when comparing public schools, subsidised schools and co-operative schools, the latter being the ones that fare best.

Ancient microbes found living beneath the icy surface of Antarctic lake
This week a pioneering study published in the Proceedings of the National Academy of Science and co-authored by Dr. Alison Murray and Dr. Christian Fritsen of Nevada's Desert Research Institute reveals, for the first time, a viable community of bacteria that survives and ekes out a living in a dark, salty and subfreezing environment beneath nearly 20 meters of ice in one of Antarctica's most isolated lakes.

Personalities influence workforce planning
What if factory foremen treated their workers less like the machines they operate, and more like people, with personality strengths and differences? Surely the workers would benefit, but might the employers also see positive results in the workplace, as well as being able to cut costs?

Deciphering bacterial doomsday decisions
Like a homeowner prepping for a hurricane, the bacterium Bacillus subtilis uses a long checklist to prepare for survival in hard times. Scientists from Rice University and the University of Houston have discovered that B. subtilis begins survival preparations well in advance of making the ultimate decision of whether to "hunker down" and form a spore. The research is available online in the Proceedings of the National Academy of Sciences.

This week's forecast: Sunny with a 40 percent chance of flu
Scientists have developed a system to predict the timing and severity of seasonal influenza outbreaks that could one day help health officials and the general public better prepare for them. The system adapts techniques used in modern weather prediction to turn real-time, web-based estimates of influenza infection into local forecasts of seasonal flu.

Impaired blood vessel function found in cystic fibrosis patients
The first evidence of blood vessel dysfunction has been found in a small cohort of generally healthy young people with cystic fibrosis, researchers report. "Even though the lung function in these kids is fine at this point, there is evidence of vascular dysfunction and exercise intolerance," said Dr. Ryan A. Harris, clinical exercise physiologist at the Medical College of Georgia and Institute of Public and Preventive Health at Georgia Health Sciences University.
