Glitchy protein production may hasten aging | Science

Cells are continually cranking out new proteins, but like car factories, they produce some lemons. A study of mice now suggests these defective proteins speed aging, bolstering an idea first proposed 60 years ago. The new paper “fills a critical gap” and “allows us to say that protein damage is an accelerant of aging,” says … Read more

News at a glance: Relaxed U.S. mask guidance, kids’ COVID-19 vaccine, and Facebook’s ‘F’ on climate misinformation | Science

COVID-19 CDC relaxes guidance on wearing masks in public The often-acrimonious U.S. debate over wearing masks entered a new phase last week when the Centers for Disease Control and Prevention (CDC) loosened its guidance and suggested about 70% of the population could jettison them. The turnabout comes as the Omicron wave ebbs and scientists consider … Read more

For LGBTQ scientists, being out can mean more publications | Science

Papers are a key currency for academic careers—which is why publication disparities among various groups, such as men versus women, are often a focal point for efforts to increase equity and diversity. Now, a new study quantifies another of these gaps: LGBTQ academic scientists who don’t disclose their sexual orientation in the workplace publish fewer … Read more

FDA pushes cancer trials to include more elderly people | Science

Older adults make up a hefty proportion of cancer patients but a much smaller slice of clinical trial participants—a long-standing and vexing problem the U.S. Food and Drug Administration (FDA) wants drug companies to tackle. The agency yesterday released recommendations urging companies to boost representation of people over 65 years old, and especially over 75. … Read more

Physicists produce biggest time crystal yet | Science

Physicists in Australia have programmed a quantum computer half a world away to make, or at least simulate, a record-size time crystal—a system of quantum particles that locks into a perpetual cycle in time, somewhat akin to the repeating spatial pattern of atoms in an actual crystal. The new time crystal comprises 57 quantum particles, … Read more

Arthritis drug reduces mortality in severe COVID-19, huge clinical trial finds | Science

Baricitinib, an oral drug that dampens an overactive immune system and is commonly used by people with rheumatoid arthritis, reduced hospitalized COVID-19 patients’ risk of dying by 13%, investigators of the world’s largest trial of coronavirus treatments announced today. Patients in the study also took other drugs, such as the steroid dexamethasone, that act on … Read more
