Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded.
Scientists report in Nature Neuroscience that a simple decision-making task does not involve the frontal lobes, where many of the higher aspects of human cognition, including self-awareness, are thought to originate. Instead, the regions that decide are the same brain regions that receive stimuli relevant to the decision and control the body’s response to it.

Billions of tons of carbon sequestered in the world’s peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change.

The evolution of novel characteristics within organisms can be enhanced when environments change in a systematic manner, according to a new study. Researchers suggest that in environments that vary over time in a non-random way, evolution can learn the rules of the environment and develop organisms that can readily generate novel useful traits with only [...]

Scientists have used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.

Sea snakes may slither in saltwater, but they sip the sweet stuff. It has been the “long-standing dogma” that the roughly 60 species of venomous sea snakes worldwide satisfy their drinking needs by drinking seawater, with internal salt glands filtering and excreting the salt. Experiments with three species of captive sea kraits captured near Taiwan, [...]

What’s your child’s “genetic destiny?” Does diabetes run in your family? Or has a genetic test indicated that your child may some day be at risk for developing heart disease?

Researchers in Spain are reporting deep new insights into how evolution changes the biochemistry of living things, helping them to adapt to new environments. Their study, based on an analysis of proteins produced by two populations of marine snails, reveals chemical differences that give one population a survival-of-the fittest edge for life in its cold, [...]

The goal in treating patients with gout is to reduce acute attacks by lowering serum urate levels, which are usually high in this disease. At the same time, high serum urate levels have been shown to lower the risk of developing Parkinson’s disease.
Scientists have developed maths-based imaging technology to measure hair on different parts of the human body.
