Study: Midlife Obesity May Spur Risk for Earlier Alzheimer's

September 1, 2015 10:08 am | by Lauran Neergaard, AP Medical Writer | Comments

One more reason to watch the waistline: New research says people's weight in middle age may influence not just whether they go on to develop Alzheimer's disease, but when.


Researchers Provide First Evidence of How Obstructive Sleep Apnea Damages the Brain

September 1, 2015 9:53 am | by UCLA | Comments

Researchers have reported the first evidence that obstructive sleep apnea contributes to a breakdown of the blood–brain barrier, which plays an important role in protecting brain tissue.


Food Craving May Be “Hard-wired” in Brains of Obese People

September 1, 2015 9:10 am | by Bevin Fletcher, Associate Editor | Comments

A new study says that the reward center in brains of obese people may react to cravings stimuli similar to an addiction, unlike the brains of healthy weight adults.


Breast Cancer Risk Score Impacts Use of Chemotherapy

August 31, 2015 10:50 am | by Duke University | Comments

A genetic test that helps predict whether some women’s breast cancer will recur might influence how chemotherapy is used, according to a new study.


New Synthetic Tumor Environments Make Cancer Research More Realistic

August 31, 2015 10:42 am | by University of Illinois | Comments

Tumors are notoriously difficult to study in their natural habitat – body tissues – but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior. Researchers have developed a new technique to create a cell habitat of squishy fluids, called hydrogels, which can realistically and quickly recreate microenvironments found across biology.


Degenerating Neurons Respond to Gene Therapy Treatment for Alzheimer’s Disease

August 31, 2015 10:23 am | by UC San Diego | Comments

Degenerating neurons in patients with Alzheimer’s disease (AD) measurably responded to an experimental gene therapy in which nerve growth factor (NGF) was injected into their brains.

Study: Tiny, Wireless Pacemaker Could Be Surgery-free Option

August 31, 2015 9:16 am | by Maria Cheng, Associated Press | Comments

A tiny, wireless pacemaker could offer some heart patients a surgery-free alternative to the traditional devices, a new study says. Some doctors, however, say there are lingering safety questions and warned patients not to rush to get the new technology.

Study Can't Confirm Results of Many Psychology Experiments

August 28, 2015 10:24 am | by Malcolm Ritter, AP Science Writer | Comments

A large group of researchers set out to repeat 100 experiments published by leading psychology journals to see how often they would get the same results. The answer: Less than half the time.


Researchers Home in on Biological Cause of ALS

August 28, 2015 10:21 am | by Stanford University | Comments

A defect in how proteins are transported inside cells may be at least partially responsible for some symptoms of amyotrophic lateral sclerosis, according to a new study.


Differences in Brain Structure and Memory Suggest Adolescents May Not ‘Grow Out of’ ADHD

August 28, 2015 10:10 am | by University of Cambridge | Comments

Young adults diagnosed with attention deficit/hyperactivity disorder (ADHD) in adolescence show differences in brain structure and perform poorly in memory tests compared to their peers, according to new research.


Study Reveals New Way to ‘Rewire’ Immune Cells to Slow Tumor Growth

August 28, 2015 9:46 am | by Yale University | Comments

Inside a tumor, immune cells and cancer cells battle for survival. The advantage may go to the cells that metabolize the most glucose, say researchers who have identified a new way to boost immune response by metabolically “rewiring” immune cells.


Modified Bacteria Become a Multicellular Circuit

August 28, 2015 9:38 am | by Rice University | Comments

Scientists have made a living circuit from multiple types of bacteria that prompts the bacteria to cooperate to change protein expression.
