An old antibiotic may combat drug-resistant tuberculosis

Drug-resistant strains of tuberculosis bacteria affect half a million people a year. A compound first discovered in the 1980s may be able to help.

Why male mosquitoes leave humans alone

Unlike their female counterparts, male mosquitoes have no desire to bite us. But the hardware for host-seeking is hidden in the male mosquito brain, locked behind a simple genetic switch. 

Rockefeller grants commercial license for the development of monoclonal antibodies for treatment of COVID-19

The treatment, a combination of two antibodies, has been shown highly capable of neutralizing SARS-CoV-2 in preclinical studies. Researchers hope it will give countries around the world, including developing countries, a way to control the rampant disease.

COVID-19 vaccines may need regular updates for emerging variants

Lab experiments suggest that the new strains reported in Britain, South Africa, and Brazil may blunt the potency of the Pfizer and Moderna COVID-19 vaccines. This could mean that the vaccines will need updates as the virus mutates.

Synthetic “micro lungs” could take COVID-19 research to the next level

Scientists have developed stem-cell technology to mass-produce tissue cultures resembling our breathing organs. These tissues offer a powerful model in which to study how SARS-CoV-2 wreaks havoc in the lungs and to screen for new drugs.

The immune system mounts a lasting defense after recovery from COVID-19

The study participants continued to improve their antibodies months after initial infection, potentially due to exposure to remnants of the virus hidden in the gut.

The blood may hold clues to some of COVID-19’s most mysterious symptoms

COVID-19 causes a host of diverse complications, from lung inflammation to blood clots, heart failure, and brain fog. A team of scientists believes these attributes may have a single culprit—and that findings from research on Alzheimer’s disease might give them a leg up in finding it.

Rockefeller begins testing of new COVID-19 antibody drug in people

Patients in the clinical trial will receive two highly potent antibodies against SARS-CoV-2 discovered at the university. Designed to prevent people with early COVID-19 from developing severe disease, the treatment is urgently needed as hospitals continue to be inundated by repeated surges of inf...

Scientists capture the moving parts of the portal to the cell’s nucleus

The proteins of the nuclear pore complex flip-flop rapidly between two orientations as they let cargo through.

Study of 50,000 people finds brown fat may protect against many diseases

People with brown fat tissue tend to burn calories more quickly, but do they also enjoy better health? Now the largest study of its kind shows that brown fat is indeed linked to reduced risk of heart disease, type 2 diabetes, and several other conditions.
