A novel compound might defeat multidrug-resistant bacteria common in hospitals

Increasingly, hospitalized patients contract infections that evade current antibiotics including colistin, long used as a last treatment option. The discovery of a new colistin variant might make it possible to outmaneuver these pathogens.

Waddling water bears, grandmother neurons, and other memorable science stories of 2021

This year's scientific endeavors included multiple attacks on SARS-CoV-2—and a lot more. Here are the most memorable science stories to come out of Rockefeller labs in 2021, from the benefits of brown fat to the pitfalls of modern IVF screening techniques.

New evidence that boosters may be crucial in protecting against Omicron

Researchers found that the antibodies present in people who have had COVID or taken two doses of mRNA vaccine are inadequate against Omicron. But their protective ability increases significantly after a booster dose.

How a fly's brain calculates its position in space

New research reveals how neurons in a fly's brain signal the direction in which the body is traveling. The cells appear to literally perform vector math in order to act as a biological compass.

Llama antibodies could help fight SARS-CoV-2 variants

Scientists have identified hundreds of llama-derived antibodies that potentially could be developed into a COVID treatment. They hope such a drug would be potent against different variants of the coronavirus, including Omicron.

Stem cell memories may drive wound repair—and chronic disease

Epidermal stem cells that hail from the hair follicle retain memories of their journey to the skin's surface. Those memories are a boon for wound repair, but may also contribute to chronic diseases and cancer.

New design may boost potency of monoclonal antibodies against COVID

In animal experiments, the structurally altered antibodies activated the immune system more effectively than those currently used in the clinic. They also proved to be more protective against the virus.

Radiotherapy may explain why childhood cancer survivors often develop metabolic disease

Radiation therapy to treat childhood cancer may damage adipose tissue, causing diabetes and coronary heart disease decades later.

Scientists discover how mitochondria import antioxidants

The finding offers researchers a direct way to investigate oxidative stress and its damaging effects in aging, cancer and other diseases.

How foodborne diseases protect the gut's nervous system

Prior infections appear to shield enteric neurons, preventing these key components of the body's "second brain" from dying off when future pathogens strike.
