Prairie voles lacking functional receptors for oxytocin form normal social bonds, a finding that could explain the hormone’s clinical failures.

Inactivating TAOK1 prompts tentacle-like protrusions to form all over a neuron’s surface, revealing the gene’s role in molding the membrane.

Mycoplasma pneumoniae with pathogenic genes replaced by biofilm-degrading ones enhance survival in a mouse model of ventilator-associated pneumonia.

A study finds that T cells induced by heroin cross the blood-brain barrier to wreak havoc on the brain, hinting at new ways to prevent withdrawal.

A study finds roflumilast can reverse sleep deprivation–induced amnesia in mice, hinting at pathways to treating memory loss in people.

A new method for isolating extracellular fluid aims to discover molecules with therapeutic potential that were previously obscured by highly abundant proteins.

A method for culturing the infectious stage of the Plasmodium lifecycle could increase malaria vaccine production efficiency by tenfold, study authors say.

A new technique, called Unclearing Microscopy, physically inflates and then stains cells to circumvent the need for expensive microscopes.

The oil’s omega-3 fatty acids accumulate in the mice’s skin, triggering an immune response that causes hair loss.

By engineering structures out of DNA, scientists could potentially prevent larger viruses, like coronaviruses and influenza viruses, from interacting with cells.

Research into how pancreatic tumors adapt to stress could lead to a new treatment approach.

By analyzing the genomes of 23 remarkably long-lived fish species, a study found two metabolic pathways associated with longevity.

Repairing damaged DNA appears to drive aging by causing the loss of epigenetic information, but restoring that information reverses such effects, a study finds.

The signature could one day be used to improve treatment planning for people with substance abuse disorders.

Data from postmortem brain tissues adds to the evidence that inflammation is associated with autism.

Female postmortem brains contain more S-nitrosylated C3 proteins, likely linked to menopause, which instruct immune cells to kill neuronal synapses.

A particular leucine-ferrying tRNA is more abundant in cancerous cells than healthy ones, and lowering its levels inhibits cancer growth, a study finds.

The expansion of mucus-degraders in the mouse gut—possibly due to poor nutrition—thins the colon’s mucus layer and may weaken defenses against blood-infecting microbes.

A study sheds light on the tiny genes that have evolved in human genomes since we split from our mammalian ancestors.
