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.
With a shortage of mental health professionals, an international team trained nurses to treat clinically depressed HIV-positive people in South Africa -- the HIV/AIDS capital of the world.
Coral sperm require a specific pH to move, which identified a signaling pathway that is shared by organisms including humans. The results have implications for how corals may fare in shifting marine conditions due to climate change.
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.
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.
The 2021 Atlantic hurricane season has now officially ended, and it's been the third most active on record.
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.
Biomedical engineers at Duke University have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin.
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.
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?
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...
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.
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.
A recent study demonstrates that magnetic resonance imaging (MRI) and artificial intelligence (AI) can be used to detect early signs of tumor cell death in response to a novel virus-based cancer therapy.
A new study has identified a promising drug candidate to minimize uncontrolled, erratic muscle movements, called dyskinesia, associated with Parkinson's disease.
With feet and legs like a peregrine falcon, engineers have created a robot that can perch and carry objects like a bird.
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...
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...
New research shows that use of a topical drug, called AB569, a combination of acidified nitrite and EDTA (or ethylenediaminetetraacetic acid) promotes killing of antibiotic-resistant bacteria while enhancing the healing of wounds in a variety of burn injuries.

Two new studies based in Seattle provide evidence that public policies to reduce consumption of added sugars through taxes on sugar-sweetened beverages are effective and sustainable.
A sperm whale with the same rare colouring as the fictional Moby Dick has been spotted off the coast of...
Construction of solar farms, wind turbines, and other sources of renewable power will soar over the next five years as nations set stricter climate policies and more ambitious emissions targets. New renewable electricity capacity will set another record this year, at 290 gigawatts, according to a new report from the International Energy Agency. That’s roughly equivalent to building nearly 300...
Dutch microbiologist Elisabeth Bik, winner of prestigious John Maddox prize, says trust in science is being underminedA “tsunami” of poor quality research is fuelling misinformation and could undermine trust in science, the winner of the prestigious John Maddox prize has warned.Elisabeth Bik, a Dutch microbiologist turned science sleuth who on Wednesday evening won the John Maddox prize for...
Biologists have successfully traced a naturally-produced melanoma-fighting compound called 'palmerolide A' to its source: a microbe that resides within Synoicum adareanum, a species of ascidian common to the waters of Antarctica's Anvers Island archipelago.

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.
