New type of taste cell discovered in taste buds

Our mouths may be home to a newly discovered set of multi-tasking taste cells that—unlike most known taste cells, which detect individual tastes—are capable of detecting sour, sweet, bitter and umami stimuli. A research ...

Neuroscience

Researcher creates neurons that light up as they fire

In a scientific first that potentially could shed new light on how signals travel in the brain, how learning alters neural pathways, and might lead to speedier drug development, scientists at Harvard have created genetically-altered ...

Immunology

How one inflammatory disorder exacerbates another

The immune system remembers. Often this memory, primed by past encounters with threats like bacteria or viruses, is an asset. But when that memory is sparked by internal drivers, like chronic inflammation, it can prove detrimental, ...
