Researchers have developed and substantiated an advanced magnetic resonance imaging (MRI) tool to reveal new structural insights into atherothrombosis, a long-term arterial vessel wall disease characterized by the build-up of lipid-rich and inflamed plaques.

Researchers hypothesized that AMD and COVID-19 share common genetic risk factors and carried out a study that identified a novel association of the two diseases with variants in the PDGFB gene. This gene encodes a platelet derived growth factor (Pdgf) which has a role in the formation of new blood vessels and is involved in the abnormal blood vessel changes that occur in AMD. They also found that...

A study of children and adolescents who received a COVID-19 vaccination following multisystem inflammatory syndrome (MIS-C) found that there were no reports of serious complications including myocarditis or MIS-C reoccurrence. About half of participants experienced mild and typical reactions, including arm soreness and fatigue. The study demonstrates that it is safe to get a vaccine after having...

Scientists have discovered that both brown and white fat is filled with thousands of previously unknown microproteins, and show that one of these microproteins, called Gm8773, can increase appetite in mice. These findings could lead to the development of a therapeutic to help people gain weight in certain disease situations, such as during chemotherapy for cancer.

Scientists show in mice how time-restricted eating influences gene expression across more than 22 regions of the body and brain. The findings have implications for a wide range of health conditions where time-restricted eating has shown potential benefits, including diabetes, heart disease, hypertension, and cancer.

If your alertness and reaction time is see-sawing more than usual, you may be more at risk of a viral illness. That's the key finding of a recent experiment.

Radiation, used to treat half of all cancer patients, can be measured during treatment for the first time with precise 3D imaging. By capturing and amplifying tiny sound waves created when X-rays heat tissues in the body, medical professionals can map the radiation dose within the body, giving them new data to guide treatments in real time. It's a first-of-its-kind view of an interaction doctors...

A new study suggests that voice and face recognition are linked even more intimately than previously thought.

'Single-cell profiling' is helping neuroscientists see how disease affects major brain cell types and identify common, potentially targetable pathways.

Researchers have shown that zebrafish can provide genetic baz1b clues to the evolution of social behaviors in humans and domesticated species.

In dual-earner couples, working from home may be a better deal for husbands than wives in some ways, according to two related studies of workers in China and South Korea.

In the far north of the planet, climate change is clearly noticeable. A new study now shows that in parallel there have been dramatic changes in pollinating insects. Researchers have discovered that the network of plants and their pollinators there has changed considerably since the end of the 19th century. Scientists warn this could lead to plants being pollinated less effectively. This, in turn,...

Antibiotics are being used less and less in fattening animals. This is the result found by the report, "Treatment Frequency and Antibiotic Consumption Quantities 2018–2021: Trends in Cattle, Pigs, Chickens and Turkeys Kept for Meat Production," by the German Federal Institute for Risk Assessment (BfR). The BfR is tasked with evaluating the data on antibiotic use provided by the German federal...

A large volcanic outburst was discovered on Jupiter's moon Io by Jeff Morgenthaler of the Planetary Science Institute using PSI's Io Input/Output observatory (IoIO).

ABC transporters constitute a major class of multidrug resistance proteins, e.g., in cancer cells. Membrane lipids have been long known to influence the structure and functional dynamics of these proteins. However, previous structural and biochemical studies on ABCG2 are limited either by their static description or low spatial resolution to provide a microscopic view of the dynamics of the drug...

A study carried out at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) heralds a paradigm change in the field of mechanobiology. The study reveals that cells respond to forces of differing strength using use two distinct mechanisms, one mediated by minute, cup-like invaginations on the cell surface called caveolae and the other by newly discovered large membrane depressions the...

Exclusive: iKnife can reliably diagnose endometrial cancer and help thousands of healthy women get all-clear quickerA revolutionary surgical knife that “smells tumours” can diagnose womb cancer within seconds, researchers have found in a breakthrough that could enable thousands of healthy women to get the all-clear quicker.The disease is the fourth most common cancer in women and affects about...

Salmonella are food-borne pathogens that infect millions of people each year. To do so, these bacteria depend on a complex network of genes and gene products that allow them to sense environmental conditions. In a new paper, researchers have investigated the role of small RNAs that help Salmonella express their virulence genes.

Researchers at Queen Mary University of London have shown that zebrafish can provide genetic clues to the evolution of social behaviors in humans and domesticated species.
