Scientists discover a mechanism of drug resistance in breast and ovarian cancer

A new study helps explain why certain cancers don't respond to treatment, and offers hope for overcoming this deadly resistance.

Deep in the fly brain, a clue to how evolution changes minds

A new study sheds light on the mysterious ways in which evolution may tweak the brain to shape behavior. It started with a close look at two Drosophila species and their mating maneuvers.

A new tactic for starving tumors

Scientists have found a metabolic particularity in tumor cells lacking oxygen. The discovery might point to new drugs to target the most difficult-to-treat spots within a tumor.

Scientists solve the case of the missing subplate, with wide implications for brain science

A new study shows that a group of neurons, previously thought to die in the course of development, in fact become incorporated into the brain’s cortex. This research has implications for understanding—and possibly treating—several brain disorders.

Troves from a search for new biomarkers: blood-borne RNA

Scientists have found a new way to trawl blood samples for snippets of RNA released by tumors or diseased organs. The method might eventually help doctors diagnose and track a wide range of medical conditions.

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 mouse’s hippocampal brain neurons flash on and off as the animal walks around with a microlens array on its head.

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.
