New studies show that elevated levels of a form of tau called p-tau217 can accurately distinguish Alzheimer’s disease from other forms of dementia, and perhaps even predict it.

Testing out combinations of antiviral proteins from llamas could help researchers create potent virus-neutralizing multimers.

Universities and healthcare facilities are planning to use spit tests to conduct large-scale screening.

In just a few months, researchers have constructed low-cost ventilators that can keep sedated pigs alive. Getting them to work safely and reliably in people is the next challenge.

Onsite testing at wastewater treatment plants could aid efforts to monitor for outbreaks of COVID-19 around the world, but such technologies are in the early stages of development.

A nearly all-female team of researchers developed a PCR diagnostic tool in a record-setting six weeks.

Lesions in the lungs of patients with pneumonia caused by a SARS-CoV-2 infection are distinct from those caused by bacteria.

The company had helped develop a tool to aid decision-making in distributing limited medical equipment among coronavirus patients, but two high-profile retractions call into question the validity of Surgisphere’s work in toto.
