How smelling death alters worm behavior
Researchers have found that the roundworm C. elegans can smell death, and it changes how the worms behave, reproduce and age.
A chance encounter with the lab
Payton Stevens never planned to become a pancreatic cancer researcher. A temporary job set him on a path from rural Kentucky to leading research on Wnt signaling and metastasis, where he now pairs discovery with mentorship and science advocacy.
Light-activated small molecule could transform eye infection treatment
Contact lenses raise the risk of infectious keratitis, a leading cause of blindness worldwide. A biotech company is commercializing a light-activated therapy using a ROS-generating molecule to rapidly kill microbes in the cornea to preserve vision.
The molecular orchestra of memory
Calcium, calmodulin and calcium/calmodulin-dependent kinase II form a molecular axis that turns fleeting neural activity into lasting memories. New research shows how memories are stabilized, and possibly even protected or repaired.
Differences in pili structure modulate bacterial behavior
Researchers demonstrate how small changes in the structure of hair-like protein appendages can affect the behavior of Acinetobacter bacteria.
Cholesterol regulatory genes predict liver transplant outcomes
Researchers identify a link between cholesterol-regulating genes and liver transplant success, which could improve donor screening and patient outcomes.
Lipid signatures for a rare neurological disorder

Disease-linked mutations disrupt protein phase behavior
Researchers find that pathogenic missense mutations are enriched threefold in phrase-separating intrinsically disordered regions of proteins.
The dual role of asprosin in chronic fatty liver disease
Researchers uncover a hormone called asprosin that may serve as a potential biomarker for the diagnosis of chronic fatty liver disease and monitoring disease progression.
Novel inhibitor targets RAS-driven cancers
Researchers in Louisville identify a small-molecule drug that blocks RALGEF signaling downstream of mutant RAS. The compound suppresses tumor growth with low toxicity, revealing a new therapeutic strategy for RAS-driven malignancies.
Catching tau in the act
Using a new proximity-labeling approach, researchers reveal how tangles of the brain-associated protein tau may disrupt RNA biology long before neurons die.
How copper delivery fuels bacterial respiration
Researchers identify the roles of several proteins in copper homeostasis in the aerobic bacterium Caulobacter vibrioides.
Revealing the glycoproteome of a cancer subtype
Researchers mapped the glycoproteome of extrahepatic cholangiocarcinoma and compared it to intrahepatic tumors. Differences in sugar modifications and immune cell content suggest new biomarkers and guide development of targeted immunotherapies.
