The Norwegian wolf is extinct

There' s no longer any doubt—the wolves found in Norway and Sweden today are actually Finnish, according to extensive studies done on their genetic makeup. Humans wiped out Norway's original wolf population in the wild around 1970.

Food paradox answer shows how ocean life survives

Ocean predators cannot survive on average concentrations of food found in the water. Instead, they survive by exploiting small patches of food-rich areas peppered throughout the world's waterways.

Safely delivering radiation to cancer patients in a 'FLASH'

Researchers at Lawrence Livermore National Laboratory (LLNL) have shown for the first time the potential for linear induction accelerators (LIAs) to deliver effective, targeted doses of "FLASH" radiation to cancer patients. The new technique selectively kills cancer cells with minimal damage to healthy cells. The approach is outlined in a Scientific...

Eye imaging technology breaks through skin by crossing beams

Biomedical engineers at Duke University have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin.

'Paradox brands' hold strong appeal for bicultural consumers

Bicultural consumers such as Asian Americans or Hispanic Americans are the fastest growing demographic in the U.S., and one of the challenges marketers face is how to build brands that resonate with consumers who have assimilated norms from different cultures and are able to code-switch between behaviors in response to social cues.

Racial stereotypes shape our perceptions of risk-takers as reckless or responsible, new study finds

Do others see you as a reckless risk-taker who behaves compulsively without weighing potential consequences? Or a courageous risk-taker who takes responsible risks?

Lunar radar data uncovers new clues about moon's ancient past

The dusty surface of the moon—immortalized in images of Apollo astronauts' lunar footprints—formed as the result of asteroid impacts and the harsh environment of space breaking down rock over millions of years. An ancient layer of this material, covered by periodic lava flows and now buried under the lunar surface, could provide new insight into the...

Researchers investigate combined effect of drought, fire on stream communities, highlighting importance of headwaters

Life is water, and water is life. This truism certainly applies to the Pacific coast, where streams and rivers function as the region's arteries. The water they carry fosters plant life and wildlife in Southern California's Mediterranean climate. They provide sanctuary during droughts and often serve as the nexus for recovery after fires.

Within an Antarctic sea squirt, scientists discover a bacterial species with promising anti-melanoma properties

There are few places farther from your medicine cabinet than the tissues of an ascidian, or "sea squirt," on the icy Antarctic sea floor—but this is precisely where scientists are looking to find a new treatment for melanoma, one of the most dangerous types of skin cancer.

Heat, no food, deadly weather: Climate change kills seabirds

The warming of the planet is taking a deadly toll on seabirds that are suffering population declines from starvation, inability to reproduce, heat waves and extreme weather.
