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 spot…

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 no…

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 ca…

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 i…

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, …

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.

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 archipe…

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 …

Researchers have identified the first non-coding RNA that controls formation of chromosome loops, which govern gene expression. Jpx RNA was previously thought to be involved only in X chromosome inactivation, a necessary step in development of female e…

Astronomers have discovered an unusually massive black hole at the heart of one of the Milky Way’s dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all ga…

Data collected by the Arecibo Radio Telescope before it collapsed late last year will help astronomers better understand how our local neighbourhood of galaxies formed. Arecibo was the world’s largest single-dish radio telescope until it was surpassed …

Unique molecular signals in the body sent to our brain and potentially our eyes immediately after we exercise could be key to helping scientists ‘bottle up’ the benefits of exercise in a pill for at-risk patients.
