Molecules in urine allow doctors to monitor skin cancer

What if you could simply provide a urine sample rather than undergo a painful surgical procedure to find out if your cancer was responding to treatment? It may seem too good to be true, but researchers at Pavol Jozef Šafárik ...

New methods could help researchers watch neurons compute

Since the 1950s at least, researchers have speculated that the brain is a kind of computer in which neurons make up complex circuits that perform untold numbers of calculations every second. Decades later, neuroscientists ...

New chemical probe for visualising brain immune cells

Researchers in South Korea and Singapore have, for the first time, developed a chemical probe that enables live-imaging of a type of immune cells in the brain, known as microglia, in a live animal brain. This discovery, led ...

Cannabidiol could help deliver medications to the brain

Cannabidiol (CBD), a non-psychoactive compound in cannabis, is being touted as beneficial for many health conditions, ranging from anxiety to epilepsy. Although much more research is needed to verify these claims, scientists ...

Are all cancer cells the same?

Take two cancer cells and compare their genomes. Surprisingly, they can be quite different. This genetic variation is one of the hallmarks of cancer, and one reason why treating cancer is so hard.

Exit through the lymphatic system

Our brain swims. It is fully immersed in an aqueous liquid known as cerebrospinal fluid. Every day, the human body produces about half a litre of new cerebrospinal fluid in the cerebral ventricles; this liquid originates ...

SPECT/CT combined with fluorescence imaging detects micrometastases

Researchers in The Netherlands have demonstrated that combining SPECT/CT and fluorescence imaging could help surgeons differentiate tumor tissue from normal tissue. The research is detailed in the featured basic science article ...

Neuroscientists now can read the mind of a fly

Northwestern University neuroscientists now can read the mind of a fly. They have developed a clever new tool that lights up active conversations between neurons during a behavior or sensory experience, such as smelling a ...
