Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, according to biologists.
Classifying native and nonnative plants on the Galapagos islands; DNA sequencing 30,000 times faster; careers for scientists as financial analysts; and more.
Worker ants of the world, unite! You have nothing to lose but your fertility. The highly specialized worker castes in ants represent the pinnacle of social organization in the insect world. As in any society, however, ant colonies are filled with internal strife and conflict. So what binds them together? More than 150 years ago, [...]

How old are you really? Chronological age is easy — count forward from birth. But establishing physiological age is purely subjective, based on how someone looks, feels and functions. Research in nematode worms is providing a crucial first step toward the development of biomarkers to predict chronological and physiological age in humans. This technology could [...]

Paintings, watercolors and prints can be used by those who manage Britain’s coastlines to look back in time and better understand the threat of rising sea levels and climate change.

What Controls Critical ‘Go-to’ Enzyme: Findings May Hold Key To Better Treatments For Many Disorders
Scientists have gained new insights into regulation of one of the body’s enzyme workhorses called calpains. As the cell’s molecular overachievers, calpains function in many cellular processes, including the movement of cells in tissues, the death of damaged cells, insulin secretion, and brain cell and muscle function. The downside of this broad set of responsibilities [...]
Theorists say atoms in a crystal can be made to behave in an unexpected way, a way that can be exploited to create tiny computer components that emit less heat and new sensors to detect bio-hazards and medical conditions.

The consumption of illicit or noncommercial alcohol is widespread in central and eastern Europe and contributes significantly to the region’s high levels of alcohol-related problems, according to a new report. While illegal alcohol consumption in western Europe is relatively low, the report finds the level of noncommercial alcohol in central and eastern Europe is so [...]

Scientists recently found evidence that bacteria and biological cells are the most efficient ice-forming catalysts in precipitation from locations around the globe. The formation of ice in clouds is important in the processes that lead to snow and rain. Ice-nucleating bacteria — which have been referred to as “rain-making bacteria” — may be significant triggers [...]

Researchers have discovered that embryonic stem cells may play a critical role in helping people with nerve damage and motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), regain muscular strength.
