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.
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.
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.
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.
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.
Chemistry Life Hacks are tips that can change your life, or at least the temperature of your beer.
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.
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.
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.
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.
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.
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.
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.
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.
Australian researchers are working with archaeologists, anthropologists and the Northern Territory's Jawoyn community to chemically analyze ancient rock art and uncover its secrets.
