A Northwestern University plague researcher has been charged with a brutal murder. Here’s what we know about him.

After a string of breaches involving anthrax, Ebola, and bird flu, the US Centers for Disease Control and Prevention has reportedly replaced the director of its Division of Select Agents and Toxins.

As the world inches closer to polio eradication, laboratories studying the virus will have to bolster biosafety standards. Eventually, most will need to stop working with the pathogen entirely.

The Defense Department reports that live samples of the deadly bacterium may have been accidentally shipped to more than 50 labs in the U.S. and abroad.

In the wake of numerous safety breaches at the federal agency, a new report finds US Centers for Disease Control and Prevention oversight “inconsistent and insufficient at multiple levels.”

Federal officials suspend research on certain pathogens at Tulane University following the escape of potentially dangerous bacteria from a high-security lab.

In the wake of numerous biosafety breaches, the US Centers for Disease Control and Prevention looks to hire a chief of laboratory safety.

A Centers for Disease Control and Prevention lab mistakenly transferred the wrong Ebola samples—ones that may have contained live virus—to another agency lab.

After a string of incidents leading to lab closures and a moratorium on the transfer of select agents, US labs are reassessing safety threats within their own walls.

Following recent high-profile safety lapses in government labs, the US Centers for Disease Control and Prevention has placed a moratorium on movement of biological materials from BSL-3 and BSL-4 facilities.

Researchers develop a new “molecular biocontainment” strategy for safely studying deadly flu viruses.

The US government has come out with new rules for life science research deemed risky.

The release of infectious agents from the lab is not uncommon, but lab-acquired infections are rare.

A second risk assessment of a proposed bio-defense laboratory shows major improvement, but still has serious flaws, according to an independent review panel.
