Scientists have demonstrated the power of artificial intelligence to predict which viruses -- like SARS-CoV-2, the virus that led to the COVID-19 pandemic -- could infect humans, which animals host them, and where they could emerge.

Researchers announce that the presence of the Bmal1 gene in the striatum affects alcohol consumption in both male and female mice in a sexually dimorphic manner. Male mice without the protein consumed more alcohol than those that had it, while female mice without the protein consumed less than females with it.

Animal farming has traditionally fulfilled human nutritional requirements for protein, but insects may serve as an alternative for direct human consumption in the future. Researchers are working to lay a foundation to develop efficient protein isolation techniques by determining the nutritional and functional properties of protein for cricket, locust and silk worm pupae powders.

The body is full of electrical signals. Researchers have now created a new nanomaterial that is capable of both detecting and modulating the electric field. This new material can be used in vitro studies for 'reading and writing' the electric field without damaging nearby cells and tissue. In addition, researchers can use this material to conduct in vitro studies to understand how neurons transmit signals but also to understand how to potentially shut off errant neurons. This may provide critical insights on neurodegeneration.

Researchers have discovered a new role for macrophages in the fight against cardiovascular disease. Macrophages have mostly been thought to drive inflammation and promote plaque build-up, but a new study shows that a subset of macrophages is actually fighting against plaque build-up within the artery.

While the world has celebrated the arrival of highly effective vaccines against COVID-19, new work shows that even unrelated vaccines could help reduce the burden of the pandemic. The study crystallizes decades of evidence suggesting that the generalized immune-boosting properties of many vaccines can cross-protect patients against multiple pathogens.

A new study that analyzed 20 years of fatal opioid overdose data in adults 55 and older found that between 1999 and 2019, opioid-related overdose deaths increased exponentially in U.S. adults ages 55 and older, from 518 deaths in 1999 to 10,292 deaths in 2019: a 1,886% increase.

Researchers have discovered a new, more effective method of preventing the body's own proteins from treating nanomedicines like foreign invaders, by covering the nanoparticles with a coating to suppress the immune response that dampens the therapy's effectiveness.

Acute myeloid leukemia (AML) is a cancer of white blood cells. Researchers discovered that AML cancer cells depend on a protein called SCP4 to survive. They think the previously little-known protein is involved in a metabolic pathway the cancer cells need to survive. SCP4 provides researchers with a potential new therapeutic approach for this aggressive cancer.

A new study reveals important insights into the molecular mechanisms that underpin the body's natural defences against the development of skin cancer. The protein CSDE1 coordinates a complex chain of events that enable senescence in skin cells. The senescent cells act as a firewall against cancer, suppressing the formation of tumours. The findings are surprising because CSDE1 has been previously linked to driving the formation of cancers. The results offer new clues into the behavior of skin cancer at the cellular level, paving the way for potential new therapeutic targets to treat the disease.
