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.


No Cable Spaghetti in the Brain

November 23, 2015 10:04 am | by Max Planck Institute | Comments

The brain is not relying on random-wiring, but self-organized neural networks for visual information processing.


Born With No Voice & Low Odds, Boy Talks With New Voice Box

November 23, 2015 9:56 am | by Lindsey Tanner, AP Medical Writer | Comments

Grant Hasse was born with two very rare conditions - one that's usually fatal, the other that should have left him unable to talk.


What's For Dinner? Genetically Engineered Salmon OK'd by FDA

November 20, 2015 9:37 am | by Mary Clare Jalonick, Associated Press | Comments

What's for dinner? Before long, it may well be genetically modified salmon, the first such altered animal cleared for human consumption in the United States.


Sense of Taste is Hardwired in the Brain, Study Shows

November 20, 2015 9:33 am | by Columbia University | Comments

Most people probably think that we perceive the five basic tastes—sweet, sour, salty, bitter and umami (savory)—with our tongue, which then sends signals to our brain “telling” us what we’ve tasted. However, scientists have turned this idea on its head, demonstrating in mice the ability to change the way something tastes by manipulating groups of cells in the brain.


Sensory Illusion Causes Cells to Self-Destruct

November 20, 2015 9:27 am | by UCSF | Comments

Magic tricks work because they take advantage of the brain’s sensory assumptions, tricking audiences into seeing phantoms or overlooking sleights of hand. Now a team of  researchers has discovered that even brainless single-celled yeast have sensory biases that can be hacked by a carefully engineered illusion, a finding that could be used to develop new approaches to fighting diseases such as cancer.


Animal Study Shows How Exercise May Energize Brain Cell Function

November 20, 2015 9:20 am | by Johns Hopkins University | Comments

Researchers discovered that an enzyme called SIRT3 that is located in mitochondria — the cell's powerhouse — may protect mice brains against the kinds of stresses believed to contribute to energy loss.


Ingestible Sensor Monitors Vital Signs

November 20, 2015 9:11 am | by Anne Trafton, MIT News Office | Comments

Doctors may one day be able to monitor patients’ vital signs by having them swallow an ingestible electronic device that measures heart rate and breathing rate from within the gastrointestinal tract.
