Researchers have resolved a longstanding scientific debate about how behavior is organized in the brain.

Researchers have discovered that the process of copying DNA generates a brake signal that stalls cell division. This molecular brake ensures that the cell has two complete copies of DNA before it divides and thus prevents DNA damage and cancer development.

Genetic ancestry tests are often advertised as a tool to uncover new connections to diverse cultures and ancestries, but new research from the University of British Columbia has found people tend to pick and choose which races they identify with based on preconceived biases.

The squeeze high blood pressure puts on fragile blood vessels in the brain appears to disrupt a normal, protective process that balances the blood flowing to our brains with the activity of our resting neurons.

Before launching their latest science experiment, researchers bought more than 200 types of tea, chocolate, herbs and other foodstuffs. The goal wasn't to stock up for long hours in the lab, but rather to find an elusive, edible contrast agent to show doctors what's happening inside our bodies.

A fairly simple test significantly improves the identification of bladder tumors that will likely become invasive.

So-called "hot" tumors filled with T cells are often considered to be more sensitive to immunotherapy compared to "cold" tumors with fewer T cells, but a clear demonstration of why has eluded cancer biologists--until now. Scientists have now discovered that whether a tumor is hot or cold is determined by information embedded in the cancer cells themselves.

A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. By what means are certain regions of this packaged DNA unpackaged and used to manufacture RNA and proteins? New work has shed light on this process, with implications for certain age-related diseases and organ decay.

Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change. This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes.

A small-molecule drug is the first to preserve hearing in a mouse model of an inherited form of progressive human deafness. The study sheds light on the molecular mechanism that underlies a form of deafness (DFNA27), and suggests a new treatment strategy.
