New Study Suggests Hallucinations, Alone, Do Not Predict Onset of Schizophrenia

October 8, 2015 10:55 am | by UNC | Comments

A new analysis identified illogical thoughts as most predictive of schizophrenia risk. Surprisingly, perceptual disturbances – the forerunners of hallucinations – are not predictive, even though full-blown hallucinations are common features of schizophrenia.


Easier Way to Fix Hearts

October 8, 2015 10:49 am | by Harvard University | Comments

Researchers have designed a specialized catheter for fixing holes in the heart by using a biodegradable adhesive and patch. The team reported in the journal Science Translational Medicine that the catheter has been used successfully in animal studies to help close holes without requiring open-heart surgery.


Researcher: Children's Cancer Linked to Fukushima Radiation

October 8, 2015 10:05 am | by Yuri Kageyama, Associated Press | Comments

A new study says children living near the Fukushima nuclear meltdowns have been diagnosed with thyroid cancer at a rate 20 to 50 times that of children elsewhere, a difference the authors contend undermines the government's position that more cases have been discovered in the area only because of stringent monitoring.


Genetic Defenses of Bacteria Don’t Aid Antibiotic Resistance

October 7, 2015 9:51 am | by University of Oxford | Comments

Genetic responses to the stresses caused by antibiotics don’t help bacteria to evolve a resistance to the medications, according to a new study.


Scientists Win Nobel Chemistry Award for Work on DNA Repair

October 7, 2015 9:32 am | by Karl Rittermalin Rising, Associated Press | Comments

Three scientists from Sweden, the U.S. and Turkey won the Nobel Prize in chemistry on Wednesday for showing how cells repair damaged DNA, work that's inspired the development of new cancer treatments.

October 7, 2015 9:05 am | by Bevin Fletcher, Associate Editor | Comments

The second round of funding for President Barack Obama’s BRAIN Initiative has been announced. The 67 new awardees of National Institutes of Health and additional investments by the Kavli Foundation were publicized Oct. 1 and will continue the large collaborative quest to develop technologies for a dynamic view of the brain.


Rare Horse Disease Shares Signs of Human Brain Disorders

October 7, 2015 8:53 am | by Bevin Fletcher, Associate Editor | Comments

Equine grass sickness, a rare nerve condition found in horses, shares similar signs of disease as people with brain disorders such as Alzheimer’s, according to a new study from the University of Edinburgh.


Single Injection Could Sterilize Large Invasive Species Populations

Scientists from the California Institute of Technology have found a way to ensure animal populations don’t grow out of control.


Microbe Sleuth

October 6, 2015 10:55 am | by Helen Knight, MIT News Correspondent | Comments

Microbes may seem small and insignificant, but in evolutionary terms the tiny organisms punch far above their weight. Although only a few micrometers in size, microbes have been responsible for shaping much of the world around us, including the air that we breathe and the ground that we walk on.


Bacteria in the World’s Oceans Produce Millions of Tons of Hydrocarbons Each Year

October 6, 2015 10:44 am | by University of Cambridge | Comments

Scientists have calculated that millions of tons of hydrocarbons are produced annually by photosynthetic bacteria in the world’s oceans.


Training by Repetition Actually Prevents Learning for Those With Autism

October 6, 2015 10:22 am | by Carnegie Mellon University | Comments

A new study published in Nature Neuroscience shows that training individuals with ASD to acquire new information by repeating the information actually harms their ability to apply that learned knowledge to other situations. This finding, by an international research team, challenges the popular educational approaches designed for ASD individuals that focus on repetition and drills.


How the Brain Builds New Thoughts

October 6, 2015 10:10 am | by Harvard University | Comments

A new study suggests that two adjacent brain regions allow humans to build new thoughts using a sort of conceptual algebra, mimicking the operations of silicon computers that represent variables and their changing values.

Rare black-footed ferrets chattered angrily before dashing out of pet carriers and ducking into burrows Monday at the Rocky Mountain Arsenal National Wildlife Refuge - a milestone for the highly endangered animals and for the former toxic waste site on the industrial edge of Denver.


Gut Bacteria Population, Diversity Linked to Anorexia Nervosa

October 6, 2015 9:53 am | by UNC | Comments

Researchers found that people with anorexia nervosa have very different microbial communities residing inside their guts compared to healthy individuals and that this bacterial imbalance is associated with some of the psychological symptoms related to the eating disorder.
