Scientists Reveal Potential Treatment for Life-Threatening Viral Infections

November 25, 2015 10:42 am | by The Scripps Research Institute | Comments

Scientists have shown for the first time how a previously unknown process works to promote infection in a number of dangerous viruses, including dengue, West Nile and Ebola. The new study also points to a potential treatment, an experimental antibiotic that appears to inhibit infection by these deadly viruses, all of which lack vaccines and treatments.


Researchers Study Alzheimer’s Disease in People with Down Syndrome

November 25, 2015 10:35 am | by Columbia University | Comments

The risk of Alzheimer’s disease—the most common cause of dementia—increases as a person ages. But the risk of Alzheimer’s is increased dramatically for adults with Down syndrome.


Umbilical Cells Help Eye’s Neurons Connect

November 25, 2015 10:29 am | by Duke University | Comments

Cells isolated from human umbilical cord tissue have been shown to produce molecules that help retinal neurons from the eyes of rats grow, connect and survive, according to researchers.


Robots: the Curiosity of the Body

November 25, 2015 10:25 am | by Max Planck Institute | Comments

Researchers have now shown in simulations with robots, that their brains, made of artificial neurons, do not need a higher-level control center for generating curiosity. Curiosity arises solely from feedback loops between sensors that provide stimuli about interactions of the robot’s body with the environment on the one hand and motion commands on the other.


New Class of RNA Tumor Suppressors Identified

November 25, 2015 10:12 am | by Stanford University | Comments

A pair of RNA molecules originally thought to be no more than cellular housekeepers are deleted in over a quarter of common human cancers, according to researchers. Breast cancer patients whose tumors lack the RNA molecules have poorer survival rates than their peers.


19 People Ill in E. Coli Linked to Costco Chicken Salad

November 25, 2015 9:31 am | by Donna Gordon Blankinship, Associated Press | Comments

The strain of E. Coli linked to Costco chicken salad that has sickened 19 people in seven states is more likely to be life-threatening than a recent foodborne illness that led to the closure of some Chipotle restaurants in the Northwest.


A Huge Chunk of a Tardigrade's Genome Comes From Foreign DNA

November 25, 2015 8:49 am | by UNC | Comments

Researchers have sequenced the genome of the nearly indestructible tardigrade, the only animal known to survive the extreme environment of outer space, and found something they never expected: that they get a huge chunk of their genome - nearly one-sixth or 17.5 percent - from foreign DNA.


Ancient Viral Molecules Essential for Human Development

November 24, 2015 10:57 am | by Stanford University | Comments

Genetic material from ancient viral infections is critical to human development, according to researchers.


Yin and Yang of Serotonin Neurons in Mood Regulation

November 24, 2015 10:51 am | by Columbia University | Comments

Low levels of serotonin in the brain are known to play a role in depression and anxiety, and it is customary to treat these disorders with medications that increase the amount of this neurotransmitter. However, a new study suggests that this approach may be too simple. It appears that neighboring serotonin-producing brainstem regions exert different and sometimes opposing effects on behavior.


Biologists Characterize New Form of mRNA Regulation

November 24, 2015 10:45 am | by University of Pennsylvania | Comments

In a new report biologists used material from both humans and plants to examine chemical modifications to messenger RNA, or mRNA, finding that the modifications appear to play a significant role in the process by which mRNAs either survive and become translated into protein or are targeted for degradation.


Infertile Worms Resist Infection-Induced Neurodegeneration

November 24, 2015 10:38 am | by Duke University | Comments

The connections are still obscure, but mounting evidence points to a link between infections, the immune system, and neurodegenerative diseases like Alzheimer’s, ALS, and Parkinson’s. Now, a team of researchers has shown that infection with live, pathogenic bacteria causes neurodegeneration in the worm C. elegans.


Nanoscientists Develop Safer, Faster Way to Remove Pollutants From Water

November 24, 2015 10:31 am | by UCLA | Comments

A team of researchers has found a new way to use enzymes to remove pollutants from water that is cost- and energy-efficient, able to remove multiple pollutants at once, and minimizes risks to public health and the environment.


Using New Gene Drive to Create Malaria-resistant Mosquitoes

November 24, 2015 10:02 am | by Lauran Neergaard, AP Medical Writer | Comments

California researchers hatched some malaria-resistant mosquitoes and then gave evolution a shove - using a groundbreaking technology to ensure the insects pass on that protective gene as they reproduce, with implications far beyond the promise of fighting malaria.


Scientists: Fungus Causes Snake Ailment, but Reason Elusive

November 23, 2015 10:21 am | by Wilson Ring, Associated Press | Comments

A fungus has been identified as the cause of a mysterious ailment that has been infecting some snake species in the eastern United States, threatening some isolated snake populations such as the timber rattlesnakes found in western Vermont.


Personalized Drug Screening on Horizon for Multiple Myeloma Patients

November 23, 2015 10:15 am | by Washington University in St. Louis | Comments

A personalized method for testing the effectiveness of drugs that treat multiple myeloma may predict quickly and more accurately the best treatments for individual patients with the bone marrow cancer. The process also may aid patients with leukemia or lymphoma.
