Pandemic

A new virus related to the deadly Nipah and Hendra viruses has been detected in shrews in the U.S. However, scientists say there is currently "no evidence" that it has infected humans and the risk of it doing so is "likely low."

Nearly 119,000 birds have been culled at a farm in California after a bird flu called H5N9 was detected among the poultry.

The COVID pandemic is ongoing, but scientists are on alert for any pathogen that might lead to another global outbreak of disease.

When human activities disrupt and unbalance ecosystems, such as by way of climate change and biodiversity loss, things go wrong.

A new laboratory study pinpoints a way H5N1 could evolve to spread from person to person.

Rising H5N1 bird flu cases in the U.S. prompted the CDC to study the virus in ferrets, revealing it may have the potential to spread and cause severe symptoms in other mammals.

Whether intentional or not, the way mega-settlements in southeastern Europe from 6,000 years ago were laid out would have cut down on the spread of disease.

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.
