Researchers have identified a link between amyloid plaques and dysfunctional neuronal conduction in animal models of Alzheimer’s disease (AD). Their study, which was published in the Dec. 1, 2022, issue of Nature, suggests new ways to think about AD, as well as badly needed potential alternatives to plaque removal to fight the disease.

A combination of radiation therapy and CD47 blockade induced an abscopal effect in animal studies even in animals that lacked T cells, researchers reported in the Nov. 21, 2022, online issue of Nature Cancer.

Diwali, the Festival of Light, marks different events depending on where it is celebrated. In some areas of India, it marks the return of Lord Rama to his birthplace of Ayodhya after defeating the demon Ravana.

Peking University researchers in collaboration with the NIH have discovered a new biochemical pathway related to a bacterium that eliminates nicotine in the intestine. The findings could lead to new ways to improve nonalcoholic fatty liver disease in smokers.

Researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne, Australia, have developed a new genome editing technique than can activate any gene, including those that have been silenced, allowing new drug targets and causes of drug resistance to be explored.

The 2022 Albert Lasker Basic Medical Research Award has been awarded to Richard Hynes, of the Massachusetts Institute of Technology, Erkki Ruoslahti, of the Sanford Burnham Prebys Medical Discovery Institute, and Timothy Springer, of Harvard Medical School.

The Nobel Prize in Physiology or Medicine 2022 was awarded to Svante Pääbo today "for his discoveries concerning the genomes of extinct hominins and human evolution." Pääbo, who is currently the director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and his colleagues overcame extreme technical challenges to sequence the DNA of ancient hominids – because after tens of thousands of years, there is no such thing as aging well for DNA.

Researchers are closer to better diagnosing and treating age-related macular degeneration (AMD) after discovering new genetic signatures of the disease by reprogramming stem cells to generate high-resolution disease models.

The controversy about the origins of the SARS-CoV-2 virus and the accusations that it escaped from the Wuhan Institute of Virology, or even that it was deliberately engineered there, could – possibly – be brought to a close by two papers published July 26, 2022.

Since the very beginning of the COVID-19 pandemic, in addition to the attempts to rapidly develop a vaccine that was effective against current strains, researchers have been looking for a vaccine that could protect more broadly against multiple coronaviruses.
