Experimenters with a powerful 'electron camera' have discovered that light whirls atoms around in perovskites, potentially explaining the high efficiency of these next-generation solar cell materials and providing clues for making better ones.

Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail. Using a wide array of ground- and space-based telescope observations, astronomers constructed one of the most detailed descriptions of a gamma-ray burst to date.

Scientists have found that stem cells in the brain's hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan.

Scientists have found surprising electron behavior that may help unravel the ever-elusive mechanism behind high-temperature superconductivity -- a phenomenon in which electrical current flows freely without resistance through a material at unusually high temperatures relative to those of conventional superconductors.

Scientists have succeeded in regenerating functional retinal cells in adult mice. Like humans, mice cannot repair damage to their retinas. However, because zebrafish can, researchers created in mice a version of the fish gene responsible for turning Muller glia into retinal cells if eye injury occurs. Researchers found way to prevent the gene's activity from being blocked as the mice got older. The new interneurons formed connections and reacted normally to signals from light-detecting cells in the retina.

Fresh insights into how cells detect damage to their DNA -- a hallmark of cancer -- could help explain how the body keeps disease in check. Scientists have discovered how damage to the cell's genetic material can trigger inflammation, setting in motion processes to remove damaged cells and keep tissues healthy.

Scientists have demonstrated how living cells can be induced to carry out computations in the manner of tiny robots or computers.

3-D laser scanning has been used to understand how plants optimize their growth, explains a new report.

Using new 3-D methods to analyze stone projectile points crafted by North America's earliest human inhabitants, scientists have found that these tools show evidence of a shift toward more experimentation about 12,500 years ago, following hundreds of years of consistent stone-tool production. The findings provide clues into changes in social interactions during a time when people are thought to have been spreading into new parts of North America.

Kidney transplant patients appear to be at a greater risk of developing melanoma than the general population and risk factors include being older, male and white, findings that corroborate results demonstrated in other studies, according to a new article.

Obese patients who underwent bariatric surgery were more like to achieve a body mass index (BMI) of less than 30 one year after surgery if they had a BMI of less than 40 before surgery, according to a study.

Inside the crater of a volcano on Graciosa Island in the Azores archipelago, in the Atlantic Ocean, an international team of researchers has discovered the bones of a new extinct species of songbird, a bullfinch which they have named Pyrrhula crassa. The remains were found in a small cavity through which time ago the lava flowed. This bird disappeared a few hundreds of years ago due to human colonization of the islands and the introduction of invasive species.

While past attempts to treat melanoma failed to meet expectations, an international team of researchers are hopeful that a compound they tested on both mice and on human cells in a petri dish takes a positive step toward creating a drug that can kill melanoma cancer cells without harming nearby healthy cells.

Despite the millions companies spend to gather information about customer satisfaction, senior managers often fail to understand those customers' expectations.

Two studies examine the personality characteristics that drive dogmatism in the religious and nonreligious. In both groups, higher critical reasoning skills were associated with lower levels of dogmatism. But these two groups diverge in how moral concern influences their dogmatic thinking.
