Proposed cuts to the federal agencies that fund scientific research could undercut America’s global competitiveness, with negative impacts on the economy and the ability to attract and train the next...

If you go up 1 mile (1.6 km), about the elevation[1] from Denver to the peaks of resorts such...
Enzymes are molecular machines that carry out the chemical reactions that sustain all life, an ability that has captured the attention of scientists like me[1].
Consider muscle movement. Your body releases a molecule called acetylcholine to trigger your muscle cells to contract. If acetylcholine sticks around for too long, it can paralyze your...
Most major biological molecules, including all proteins, DNA and RNA, point in one direction[1] or another. In other words, they are chiral, or handed[2]. Like how your left glove fits only your left hand and your right glove your right hand, chiral molecules can interact only with other molecules of compatible handedness.
Two chiralities...
