Sound sleep in young and middle-aged people helps memory and learning, but as they hit their seventh, eighth and ninth decades — and generally don’t sleep as much or as well — sleep is not linked so much to memory, a researcher says...
Protoplanet Vesta, visited by NASA's Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its surface. However, a new study shows evidence that Vesta may have had short-lived flows of water-mobilized material on its surface, based on data from Dawn.
NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens.
Epigenetic changes are implicated in a host of neural conditions, from Alzheimer's-related memory loss to depression. Now, a revolutionary set of molecular editing tools is allowing scientists to alter the epigenome like never befor...
In a novel twist in cybersecurity, scientists have developed a self-cleaning, self-powered smart keyboard that can identify computer users by the way they type. The device could help prevent unauthorized users from gaining direct access to computers.
The topic of arsenic in the U.S. diet has sparked considerable public interest following publication of an article analyzing arsenic findings from fruit juices and rice products. Researchers now write about how levels of consumer exposure to arsenic are still below levels of toxicological concern.
Scientists have precisely characterized a manganese catalyst's electronic states. The catalyst is capable of converting light to chemical energy. If sunlight could effortlessly be converted to chemical energy, our energy troubles would be a thing of the past.
Many health advocates advise people to eat an orange and drink water rather than opt for a serving of sugary juice. But now scientists report that the picture is not clear-cut. Although juice is indeed high in sugar, the scientists found that certain nutrients in orange juice might be easier for the body to absorb than when a person consumes them from unprocessed fruit.
In their decades-long search for vaccines against drugs of abuse, scientists have hit upon a new approach to annul cocaine's addictive buzz. They report that their strategy, which they tested on mice, harnesses a bacterial protein to trigger an immune system attack on the drug if it enters the body. Show More Summary
The Russian Far East is the setting for a Cinderella story. In this case, Cinderella is a tiger. An orphaned, starved, frost-bitten cub was rescued in the winter of 2012, rehabilitated, released, and now is possibly mating and re-colonizing former tiger territory, according to new research.
Both epidemiological and pre-clinical studies have suggested that coffee consumption has a protective effect against non-melanoma skin cancers. However the protective effect for cutaneous melanoma (malignant and in situ) is less clear, according to a new study.
An international team of scientists have joined forces to lay the foundations for an experiment of truly astronomical proportions: putting together the biggest map of the Universe ever made. The experiment will combine signals from hundreds of radio dishes to make cosmic atlas. The international team of researchers has now set out their plans for the mammoth survey.
Optimization algorithms, which try to find the minimum values of mathematical functions, are everywhere in engineering. Among other things, they're used to evaluate design tradeoffs, to assess control systems, and to find patterns in data. Show More Summary
Individual protons and neutrons in atomic nuclei turn out not to behave according to the predictions made by existing theoretical models. This surprising conclusion, reached by an international team of physicists, forces us to reconsider how we have been describing large atomic nuclei for the past several decades.
An expedition to Antarctica yields new information about how climate change affects Antarctic glaciers. The study has discovered a new ecosystem, researchers report, including a unique ecosystem of fish and invertebrates living in an estuary deep beneath the Antarctic ice.
Four out of ten American children live in low-income families, according to latest research from the National Center for Children in Poverty (NCCP). This finding underscores the magnitude of the problem of family economic insecurity and child poverty in the United States. Show More Summary
About 300 scientists used more than 30,000 brain scans and DNA samples to find eight gene mutations that affect the size of specific parts of the brain. The study could help identify people who would most benefit from new drugs designed to save brain cells, but more research is necessary to determine if the genetic mutations are implicated in disease, the researchers say.
The benefits of fish consumption on prenatal development may offset the risks associated with mercury exposure, new findings from research in the Seychelles suggests. In fact, the new study suggests that the nutrients found in fish have properties that protect the brain from the potential toxic effects of the chemical.
The researchers found that salmon flesh treated with UHP at levels greater than or equal to 400 MPa improved the color, hardness, and chewiness of the flesh, and inhibited microorganism proliferation, thus increasing shelf life.
Scientists have developed a new technique to generate more powerful, more energy efficient and low-cost pulsed lasers. The technique has potential applications in a number of fields that use pulsed lasers including telecommunications, metrology, sensing and material processing. Show More Summary
