How funders can improve transparency to foster efficiency and diversity in research

Altering the rate of respiration in mitochondria changes how fast neurons grow, making mouse neurons grow more like human ones and vice versa, a study finds.

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.

Scientists discover how to convert the brain’s glial cells into multipotent neural stem cells.

Mechanically sensitive gut cells similar to touch sensors in the skin allow the intestine to feel and assess the physical properties of its contents.

Clinicians and researchers teamed up to investigate how inappropriate proinflammatory mechanisms contribute to the pathogenesis of drug-refractory epilepsy.

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