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.

Eye imaging technology breaks through skin by crossing beams

Biomedical engineers have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The new 'dual-axis' approach opens new possibilities for OCT to be used in applications such as spotting skin cancer, assessing burn damage and healing progress, and guiding surgical procedures.

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 Reports paper.

'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.

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 Moon's deep past, according to a team of...

New way of identifying early risk of cardiovascular disease

The risk of developing cardiovascular disease is strongly associated with 'bad' LDL cholesterol. A large study now shows that two proteins that transport cholesterol particles in the blood provide early and reliable risk information. The researchers now advocate introducing new guidelines for detecting cardiac risk and say the results may pave the way for early treatment, which could help lower...

Targeting the brain’s immune cells may help prevent or treat Alzheimer’s disease

A gene mutation linked to Alzheimer's disease alters a signaling pathway in certain immune cells of individuals with the disease, according to a new study. The team also found that blocking the pathway -- with a drug that's currently being tested in cancer clinical trials -- protects against many features of the condition in a preclinical model. The results could lead to new strategies to block...
