In our digital world, are young people losing the ability to read emotions?

13 hours 48 min ago
Are young people losing the ability to read emotions in our digital world? Scientists report that sixth-graders who went five days without even glancing at a smartphone, television or other screen did substantially better at reading emotions than sixth-graders from the same school who, as usual, spent hours each day looking at their smartphones and other screens.

Creating pomegranate drug to stem Alzheimer's, Parkinson's

13 hours 50 min ago
Research will look to produce compound derivatives of punicalagin for a drug that would treat neuro-inflammation and slow down the progression of Alzheimer's disease, scientists report. The onset of Alzheimer's disease can be slowed and some of its symptoms curbed by a natural compound that is found in pomegranate. Also, the painful inflammation that accompanies illnesses such as rheumatoid arthritis and Parkinson's disease could be reduced, according to the findings of the two-year project.

Epigenetic changes in children with Crohn's disease seen in study

13 hours 50 min ago
A wide range of epigenetic changes -— alterations in DNA across the genome that may be related to key environmental exposures -— in children with Crohn's disease (CD), has been observed and reported in a new study. Crohn's disease is a painful, medically incurable illness that may attack anywhere along the digestive system. Crohn's disease and ulcerative colitis, which involves only the large intestine (colon), are the two main types of inflammatory bowel disease.

Voyager map details Neptune's strange moon Triton

13 hours 55 min ago
NASA's Voyager 2 spacecraft gave humanity its first close-up look at Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager's historic footage of Triton has been "restored" and used to construct the best-ever global color map of that strange moon. The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25, 1989.

Playing hunger games: Are gamified health apps putting odds in your favor?

14 hours 48 min ago
For many people, finding motivation to exercise is a challenge. Thankfully, there are Zombies chasing you. At least that's the approach of Zombies, Run! -- one of more than 31,000 health and fitness apps on the market today, and one of the growing number of apps that use games to increase physical activity. Gamification is currently the popular trend for mobile fitness apps, but whether or not it's the best way to exercise remains to be seen.

Low birth weight linked to higher incidence of type 2 diabetes in African American women

14 hours 50 min ago
African American women born at a low or very low birth weight may be at a higher risk for developing type 2 diabetes. The findings may explain in part the higher occurrence of type 2 diabetes in African American populations, which has a high prevalence of low birth weight.

Fungus deadly to AIDS patients found to grow on trees

14 hours 50 min ago
Researchers have pinpointed the environmental source of fungal infections that have been sickening HIV/AIDS patients in Southern California for decades. It literally grows on trees. The discovery is based on the science project of a 13-year-old girl, who spent the summer gathering soil and tree samples from areas around Los Angeles hardest hit by infections of the fungus named Cryptococcus gattii (CRIP-to-cock-us GAT-ee-eye).

Coronary calcium predicts heart disease risk in patients with chronic kidney disease

14 hours 50 min ago
Calcium build-up in the coronary artery walls was more useful for correctly predicting kidney disease patients' risk of heart disease than other measures of atherosclerosis, such as thickness of the carotid artery walls and narrowing of the arteries in the legs, a new study reports.

Plants: Calcium and reproduction go together like the birds and the bees

14 hours 50 min ago
Everyone's heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research reports discoveries in the chemical signaling process that guides flowering plant fertilization.

Water splitter runs on an ordinary AAA battery

14 hours 50 min ago
Although touted as zero-emissions vehicles, most fuel cell vehicle run on hydrogen made from natural gas. Now scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in this device are made of inexpensive and abundant nickel and iron.

Climate change could see dengue fever come to Europe

14 hours 51 min ago
Dengue fever could make headway in popular European holiday destinations if climate change continues on its predicted trajectory, according to research. The study used current data from Mexico, where dengue fever is present, and information about EU countries to model the likelihood of the disease spreading in Europe. They found that coastal regions around the Mediterranean and Adriatic seas, the Po Valley and North East Italy were most at risk.

Spectacular supernova's mysteries revealed

14 hours 51 min ago
Astronomers are delving into the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year. The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance. These phenomena are extremely important to study because they provide key information about our universe, including how it is expanding and how galaxies evolve.

Striatum acts as hub for multisensory integration

14 hours 51 min ago
A new study provides insight on how the brain processes external input such as touch, vision or sound from different sources and sides of the body, in order to select and generate adequate movements. The findings show that the striatum acts as a sensory ‘hub’ integrating various types of sensory information, with specialized functional roles for the different neuron types.

Water quality in glass, plastic bottles: Better than expected in Spanish study

14 hours 51 min ago
Bottled water sold in Spain is practically free of constituents given off by plastic packaging or glass bottle lids. They are only detected in some cases, albeit in quantities much lower than limits found harmful for health, an analysis of more than 130 types of mineral water reveals. Plastic materials used in food packaging are made up of small molecules or monomers which, together with their additives, can migrate into the product during packaging manufacturing, filling or storage.

Breakthrough in imaging gold nanoparticles to atomic resolution by electron microscopy

14 hours 52 min ago
Nanometer-scale gold particles are intensively investigated for application as catalysts, sensors, drug delivery devices, biological contrast agents and components in photonics and molecular electronics. Gaining knowledge of their atomic-scale structures, fundamental for understanding physical and chemical properties, has been challenging. Now, researchers at have demonstrated that high-resolution electron microscopy can be used to reveal a three-dimensional structure in which all gold atoms are observed.

Extracorporeal support can significantly increase number of organs for transplant

14 hours 54 min ago
Using heart-lung support technology, one Transplant Center was able to increase the number of kidneys, livers and pancreases available for transplant by about 20 percent. As of Aug. 6, 2014, 123,191 people nationwide were waiting for a solid organ transplant in the United States. The Institute of Medicine has named donation after circulatory determination of death as the number one research priority to improve organ donation.
