One of the biggest challenges for single-cell research is picking out only one cell from a collection of millions - problem solved
Scientists at the Houston Methodist Research Institute have figured out how to pick up and transfer single cells using a pipette - a common laboratory tool that's been tweaked slightly. (Medical News Today)

Treating pain by blocking the 'chili-pepper receptor'
Biting into a chili pepper causes a burning spiciness that is irresistible to some, but intolerable to others. (Medical News Today)

Slippery material for lubricating joints inspired by nature
A natural molecule found in the fluid surrounding healthy joints provides the inspiration for scientists developing slippery materials for artificial joints and moving surfaces. (Medical News Today)
