Several lines of evidence suggest that targeting the body’s defense pathways might help treat a subset of people with the psychiatric disorder. But many open questions remain.

The concept of epigenetic inheritance has long been controversial. Some researchers hope that new data on cross-generational effects of environmental exposures will help settle the debate.

A growing appreciation of the bacterial assemblages that live within tumors has researchers striving to understand and capitalize on their role.

A new link between inflammation and rampant chromosomal abnormalities reveals novel strategies to treat diverse malignancies.

Corals that previously experienced heat stress respond better the next time around. Researchers are trying to figure out how, and hope to one day take advantage of the phenomenon to improve coral restoration efforts. 

Researchers explore the idea that molecular patterns in individual cells could underlie the development of a left and a right in animals.

Long lambasted as junk DNA or genomic parasites, transposable elements turn out to be contributors to adaptation.

Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.

Immunologists and parasitologists are working to revive the idea that helminths, and more specifically the molecules they secrete, could help treat allergies and autoimmune disease.

The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.

Certain stretches of DNA that regulate gene expression have evolved differently from protein-coding genes.

Recent findings buck the traditional idea that embryos are passive agents and instead suggest that by tuning into vibrations, organisms can better prepare to enter the outside world.

Our perception of quantity, separate from counting or estimation of magnitude more generally, is foundational to human cognition, according to some neuroscientists.

The single-celled fungus allows researchers to study Alzheimer’s, Parkinson’s, ALS and other brain diseases with unparalleled speed and scale.

Researchers’ painstaking examinations have begun to reveal how the virus wreaks havoc in multiple organs and tissues.

A year and a half into the pandemic, the long-term effects of SARS-CoV-2 infection are garnering more research attention as millions of long COVID patients emerge.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

With human research trials resulting in dozens of successful deliveries in the US and abroad, doctors move toward offering the surgery clinically, while working to learn all they can about uterine and transplant biology from the still-rare procedure.

Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.
