Global warming threatens Antarctic sea life

Climate change is causing Antarctic sea life to face an invasion of predatory king crabs and exotic species, potentially devastating the region's unique ecosystem. Rising temperatures are allowing these species to expand their habitats, disrupting delicate ecological relationships and putting the world's last truly wild places at risk.

New plasma transistor could create sharper displays

Researchers created a plasma transistor to control plasma conduction current and light emission with an emitter voltage of 5 volts or less, enabling lighter, less expensive, and higher resolution flat-panel displays. The device uses a microcavity plasma containing electrically charged gas, which radiates light depending on the gas inside.

Beaming new light on life

Physicists and chemists at the University of Utah developed a new method using silver nanoparticles to visualize internal structures in nearly opaque biological materials. The technique allows for the detection of fatigue in materials like carbon-fiber plastics used in aircraft, enabling regular inspections of fuselage integrity.

Research to provide information of long-term effects of childhood cancer treatment to parents

A study published by researchers at Rhode Island Hospital found that parents of childhood cancer survivors continue to need information about the late effects of treatment, which can include memory and concentration problems. The study suggests that early provision of this information may help prevent parental distress and recommends t...

World's biggest snake gives climate clues

Researchers found a colossal boa constrictor-like creature that stretched longer than a city bus and weighed over 1.25 tons, providing a rare window into past equatorial environment. The discovery suggests the mean annual temperature at equatorial South America during that time was nearly 33 Celsius, about six degrees warmer than today.

Xenophobia, for men only

A new study by Michigan State psychologist Carlos David Navarrete found that men's fears are reserved for members of their own gender when it comes to out-groups. The findings suggest that this fear is linked to evolutionary history, with male faces being a potent cue for danger.
