Race Should be Removed from Genetics Research, Paper Contends

February 8, 2016 | by Seth Augenstein, Digital Reporter | Comments

Race should no longer be used as a distinguishing factor in human biology and genetics research, contends a new paper in Science.


Studies Aim to Restore Habitat of Imperiled Northwest Fish

February 9, 2016 10:54 am | by Keith Ridler, Associated Press | Comments

Scientists in the Pacific Northwest are studying more than a dozen watersheds to develop templates on habitat restoration that could be used in similar streams to bolster struggling fish populations.


Flashing Light at Night Adjusts Sleep Cycle

February 9, 2016 10:46 am | by Stanford University | Comments

Exposing people to short flashes of light while they’re sleeping could provide a fast and efficient method of preventing jet lag, according to a new study.


Discovery May Lead To Better Egg Screening And IVF Outcomes

February 9, 2016 10:41 am | by UCSF | Comments

Experts in in-vitro fertilization (IVF) have discovered a pattern of protein secretion during egg maturation that they say has the possibility of leading to a new, non-invasive test to evaluate the fitness of eggs before they are fertilized in the clinic.


Study Examines Evolution of Cancer

February 9, 2016 10:29 am | by Yale University | Comments

A novel study answers age-old questions about how cancers spread by applying tools from evolutionary biology. The new insights will help scientists better understand the genetic origins of tumor metastases, and lead to more effective targets for treatment, said the researchers.


Sighing is Vital to Lung Function

February 9, 2016 10:23 am | by UCLA | Comments

Contrary to the words immortalized by the piano singer in “Casablanca,” a sigh is far more than a sigh. Heaving an unconscious sigh is a life-sustaining reflex that helps preserve lung function.


Roach-like Robots May Help in Disasters

February 9, 2016 10:17 am | by Seth Borenstein, AP Science Writer | Comments

When buildings collapse in future disasters, the hero helping rescue trapped people may be a robotic cockroach.


Sleeping Difficulty Associated with Type 2 Diabetes

February 9, 2016 9:20 am | by Bevin Fletcher, Associate Editor | Comments

A new study strengthens evidence that sleep problems put women at higher risk for developing Type 2 diabetes.


New Drug Target for Rett Syndrome

February 8, 2016 10:13 am | by Harvard University | Comments

Researchers have identified a faulty signaling pathway that, when corrected in mice, ameliorates the symptoms of Rett syndrome, a devastating neurological condition. The findings could lead to the discovery of compounds or drugs that may benefit children affected by the disease.


Uncovering the Secrets of Elastin’s Flexibility

February 8, 2016 10:08 am | by David L. Chandler, MIT News Office | Comments

Elastin is a crucial building block in our bodies. Its flexibility allows skin to stretch and twist, blood vessels to expand and relax with every heartbeat, and lungs to swell and contract with each breath. But exactly how this protein-based tissue assembles itself to achieve this flexibility remained an unsolved question — until now.


Discovery: Many White-tailed Deer Have Malaria

February 8, 2016 9:53 am | by University of Vermont | Comments

Two years ago, Ellen Martinsen, was collecting mosquitoes at the Smithsonian's National Zoo, looking for malaria that might infect birds--when she discovered something strange: a DNA profile, from parasites in the mosquitoes, that she couldn't identify.


Florida Readies for a Fight with Zika Virus

February 5, 2016 10:51 am | by Jennifer Kay, Associated Press | Comments

Florida's history of fighting off mosquito-borne outbreaks puts the state in perhaps better position than most when it comes to the Zika virus.


Karolinska University to Investigate Stem-cell Scientist

February 5, 2016 10:48 am | by The Associated Press | Comments

Sweden's Karolinska University says it is commissioning an external investigation into stem-cell scientist Paolo Macchiarini, who was cleared last year of misconduct charges related to his creation of wind pipes made from patients' stem cells.


How Gut Inflammation Sparks Colon Cancer

February 5, 2016 10:46 am | by Duke University | Comments

Chronic inflammation in the gut increases the risk of colon cancer by as much as 500 percent, and now researchers think they know why.


Natural Protein Points to New Inflammation Treatment

February 5, 2016 10:42 am | by NIH/National Institute of Environmental Health Sciences | Comments

Increasing the level of a naturally-produced protein, called tristetraprolin (TTP), significantly reduced or protected mice from inflammation, according to researchers. The results suggest that pharmaceutical compounds or other therapeutic methods that produce elevated levels of TTP in humans may offer an effective treatment for some inflammatory diseases, such as rheumatoid arthritis, psoriasis, and multiple sclerosis.
