Drowsy worms offer new insights into the neuroscience of sleep
Scientists studying worms have discovered a group of cells that help the body transition from wakefulness to slumber.
Genetic mutation identified as culprit in rare infectious disease
Researchers have uncovered the genetic factors that make some people susceptible to Whipple's disease, an intestinal inflammatory disorder that causes diarrhea, pain, and weight loss.
New molecular views of how neurons pace their signals
Detailed structural images reveal how an ion channel helps curtail a neuron’s firing. The work has relevance for diseases in which this molecule malfunctions.
A first look at the earliest decisions that shape a human embryo
For the first time, scientists have shown that a small cluster of cells in the human embryo dictates the fate of other embryonic cells. The discovery of this developmental “organizer” could advance research into many human diseases, and it suggests we have more in common with birds than meets the...
A new way to watch brain activity in action
A new imaging tool makes it possible to track the firing of millions of brain cells in mice while the animals move about as normal. The method could help shed new light onto the neural processes that create behavior.
New method allows scientists to study how HIV persists
Scientists have developed a new strategy to study the cells that host hidden reserves of dormant HIV, a step that may lead to new treatments that go beyond controlling the infection and instead aim to eradicate the virus entirely.
From infection-dodging stem cells, new tactics for research on viral disease
Among other superpowers, stem cells have a knack for fending off viruses like dengue and zika. Scientists have gained new insight into these curious defense strategies—knowledge they say could fuel the development of drugs against a range of diseases.
Structural studies help explain how cancer cells resist chemotherapy
New research sheds light on how some cancer cells use molecular pumps to expel chemotherapy drugs before they have a chance to work.
What happens to a dying cell’s corpse? New findings illuminate an old problem
Scientists have discovered a curious way for cells to die. In studying it, they are learning about how remnants of diseased cells are normally chewed up and removed.
Scientists map the portal to the cell’s nucleus
The gateway to cellular headquarters has 552 components. A new map that shows how all these pieces fit together could help scientists study numerous diseases.
