Engineered virus-like particles can outcompete HIV in the body, potentially offering long-term viral suppression after a single dose, a monkey study suggests.

Predicting dangerous tipping points in complex systems has proven to be a headache for scientists. Now, a new AI system could be poised to do the job for them.

Better prevention is driving down heart-attack rates in the U.S., but the sharp drops seen at the height of the pandemic were likely caused by people avoiding medical care.

Flu viruses that can use a second cellular entry point may move more effectively between animals and humans, scientists say.

Bird flu in cows and goats has raised alarm in the U.S. To date, four people are thought to have caught the virus from cattle, but the risk to the general public is low.

This infection, tied to an ongoing outbreak in cows, is the first in the U.S. to cause respiratory symptoms, but not the first H5N1 case in the world to do so.

About 500 more people died from drowning each year between 2020 and 2022 than did in 2019, the CDC reports.

The patient is being treated with an antiviral drug and is believed to have been in contact with dairy cows infected with H5N1 avian influenza.

The Bulletin of the Atomic Scientists cited the threat of nuclear escalation in Ukraine, climate change and disruptive technologies as reasons to keep the clock at 90 seconds to midnight.

Evidence suggests the outbreak is being caused by several known pathogens, the World Health Organization said.
