Chemists Examine Enzyme Responsible for Food Browning

September 10, 2014 7:00 am | by Univ. of Vienna | News | Comments

Researchers have explored the mechanisms behind the "browning reaction" during the spoilage of mushrooms. They were able to demonstrate that the enzyme responsible is already formed prior to fungal spoiling.

Water Ice Clouds Found Outside Solar System

September 10, 2014 7:00 am | by Carnegie Institution | News | Comments

Scientists have discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets— Jupiter, Saturn, Uranus and Neptune— but have not been seen outside of the planets orbiting our Sun, until now.

Exercise Prior to School May Reduce ADHD Symptoms

September 10, 2014 7:00 am | by Michigan State Univ. | News | Comments

Paying attention all day in school as a kid isn’t easy, especially for those who are at a higher risk of ADHD, or attention deficit hyperactivity disorder. Now, a study shows that offering daily before-school, aerobic activities to younger at-risk children could help in reducing the symptoms of ADHD in the classroom and at home.

Molecular Target Key to Better Brain Plasticity

September 10, 2014 7:00 am | by Tel Aviv Univ. | News | Comments

As Alzheimer's disease progresses, it kills brain cells mainly in the hippocampus and cortex, leading to impairments in "neuroplasticity," the mechanism that affects learning, memory and thinking. Targeting these areas of the brain, scientists hope to stop or slow the decline in brain plasticity. New research has discovered a way to preserve the flexibility and resilience of the brain.

Diet, Body Fat Linked to Brain Chemistry

September 10, 2014 7:00 am | by NIH/National Institute of Diabetes and Digestive and Kidney Diseases | News | Comments

People who are obese may be more susceptible to environmental food cues than their lean counterparts because of differences in brain chemistry that make eating more habitual and less rewarding. Researchers found that, when examining 43 men and women with varying amounts of body fat, obese participants tended to have greater dopamine activity in the habit-forming region of the brain than lean counterparts.

Smart Diaper Monitors Baby's Health

September 9, 2014 2:00 pm | by UC Riverside | News | Comments

A team of students created an inexpensive pad that can be inserted into diapers to detect dehydration and bacterial infections in infants. The product operates much like a home pregnancy test or urine test strip. Chemical indicators change color when they come in contact with urine from an infant who is suffering from dehydration or a bacterial infection.

Scientists Chart Ebola Risk

September 9, 2014 2:00 pm | by Univ. of Oxford | News | Comments

A new map identifies areas where animals are likely to be infected with the Ebola virus as a first step toward understanding where future outbreaks of the disease may occur. The map, based on a model created by scientists, predicts that in animal populations the Ebola virus is likely to be circulating across a vast swathe of forested Central and West Africa.

Mapping Cell Metabolism Aids Study of Obesity

September 9, 2014 2:00 pm | by Purdue Univ. | News | Comments

Researchers have shown how to use a new imaging platform to map lipid metabolism in living cells, discovering specifically where cholesterol is stored and pointing toward further studies in obesity, diabetes and longevity.

Treating Autistic Infants Reduces Symptoms

September 9, 2014 2:00 pm | by UC Davis | News | Comments

Treatment at the earliest age when symptoms of autism spectrum disorder (ASD) appear– sometimes in infants as young as six months old– significantly reduces symptoms so that, by age three, most who received the therapy had neither ASD nor developmental delay.

CO2 Pollution Hit Record Levels in 2013

September 9, 2014 2:00 pm | by Associated Press, John Heilprin | News | Comments

An annual report said that carbon dioxide, the heat-trapping gas blamed for the largest share of global warming, rose to global concentrations of 396 parts per million last year, the biggest year-to-year change in three decades.

USDA Announces $328 M Conservation Plan

September 9, 2014 2:00 pm | by Associated Press, Steve Karnowski | News | Comments

The USDA announced $328 million in funding to protect and restore farmlands, grasslands and wetlands across the country. The initiative, using money provided in the new five-year farm bill, will buy conservation easements from farmers to protect the environment, help wildlife populations and promote outdoor recreation.

Textbooks May be Wrong About Volcanoes

September 9, 2014 2:00 pm | by Caltech | News | Comments

In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study from researchers. New seismology data are confirming that such narrow jets don't actually exist.

Egyptian Art Paints Picture of Ecological Collapse

September 9, 2014 7:00 am | by UC Santa Cruz | News | Comments

Depictions of animals in ancient Egyptian artifacts have helped scientists assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years. A new analysis of this record shows that species extinctions, probably caused by a drying climate and growing human population in the region, have made the ecosystem progressively less stable.
