The decision to eat may come down to these three neurons

Manipulating a newly identified neural circuit can curb appetite—or spur massive overeating.

New discovery offers hope for vastly improved myasthenia gravis treatment

A new, enzyme-based drug dramatically outperforms existing treatments in mouse models, paving the way for future clinical trials and the potential to treat myasthenia gravis and similar diseases.

In studying the mating rituals of fruit flies, scientists may have learned something about how brains evolve

Researchers have identified how the architecture of brain circuits helps different species flexibly adapt to new mating signals across evolutionary timeframes.

West Nile infections are spiking. Here’s why the percentage of severe cases is so small

An autoimmune condition makes certain people much more susceptible to West Nile virus and many other severe viral diseases. In the future, a screening process could reveal if you’re at risk.  

Surprising reason that B cells benefit from booster shots

New research solves the mystery of how two different types B cells work in tandem to fight off re-infections, with implications for vaccine boosting strategies.

Could a bout of COVID protect you from a severe case of flu?

New findings on how past viral respiratory infections affect future, unrelated ones could lead to therapies for boosting general antiviral immunity—and potentially better pandemic preparedness.

Why a promising breast cancer drug doesn’t work—and how to improve it

A treatment that appears effective in cancers such as myelofibrosis consistently fails in breast cancer clinical trials. A new study explains why.

Cancer cells may be using lipids to hide from the immune system

New study demonstrates that one type of lipid is so critical for immune evasion that certain cancers cannot proliferate without them. Modulating intake of dietary lipids could open up an avenue for treatment.

New findings on TB could change how we treat inflammatory disorders    

The study explains why treatments for many autoimmune and inflammatory diseases raise the risk of contracting TB—and also upends long-held assumptions about what kicks off an immune response.
