After taking a pill, the drugs it contains are distributed throughout the body, reaching the tissues and cells affected by disease and performing their intended function. However, they also enter healthy cells, where they often cause more harm than good.

Engineers teach spacecraft to 'dream' their way to the space station
Docking with the ISS may seem simple. However, actually doing so shows how difficult orbital mechanics can be. It's like traveling down a highway at 28,000 km/hr (17,000 mph) and parallel parking in an open garage on a multibillion-dollar laboratory traveling at the same speed. I

Scientists discover an “impossible” cellular survival pathway that could help fight cancer
Scientists discovered a surprising backup system that lets mammalian cells make the essential amino acid cysteine even when the pathways once considered indispensable are disabled. The same survival mechanism may help cancer cells resist treatment, raising the possibility that sh
