Horseshoe crabs play a unique role in medicine, but they’re also ecologically important in their home waters along the Atlantic coast. Can regulators balance the needs of humans and nature?
Your cells die to keep you alive. Cell death does everything from fighting cancer cells and pathogens to forming your fingers and toes.
Warmer ocean waters are fueling the spread of the bacteria Vibrio vulnificus. Infections can lead to a rare but fatal condition called necrotizing fasciitis.
West Nile virus arrived in North America in 1999 and spread across the continent by 2005. Here’s what you need to know about this mosquito-borne pathogen.
The heat and chills that come with fever are not only uncomfortable but also metabolically costly. Increased body temperature, however, can make all the difference when you’re sick.

An overactive immune response to infection can be deadly. Studying how one key player called tumor necrosis factor, or TNF, induces lethal immune responses could provide new treatment targets.
An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.
Phages, or viruses that infect bacteria, can lie dormant within chromosomes until they’re triggered to replicate and burst out of their hosts.
