Bacteria ganging up on drugs
With the discovery of sulfa drugs and antibiotics came man’s confidence in his ability to control infectious diseases. But now, that confidence is being shaken by once defenseless germs that have learned to outwit man and thrive in the face of his wonder drugs.… One way to cut down on drug resistance transfer is to stop prescribing antibiotics almost...
I’m warning you up front. There’s heartbreak in this issue. In two stories, Science News writers investigate new facets of the ongoing opioid epidemic in the United States. According to the Centers for Disease Control and Prevention, 91 Americans die on average each day from opioid overdoses, quadruple the deaths from opioid overdoses in 1999. Today, nearly half of those deaths...05/31/2017 - 16:00 Health, Science & Society

Proton puzzler05/31/2017 - 15:45 Particle Physics, Climate, Planetary Science
Uncertainty over the proton’s size, spin and life span could have physicists rethinking standard notions about matter and the universe, Emily Conover reported in “The proton puzzle” (SN: 4/29/17, p. 22).
Readers wondered about the diameter (or size) of the proton, which has three fundamental particles called quarks rattling around inside. “Still scratching my head over...
The first thing you’ll notice is the noise. Monitors beep steadily, relentlessly, ready to sound a car-alarm blare if a baby is in trouble.
The air has an astringent odor — not clean exactly, but reminiscent of an operating room (there’s one next door). Ceiling lights shine fluorescent white. Half are off, but glare from the monitors throws out extra light. It’s midday on a Friday, but...
The Science Life
When the eyes of her mice looked normal, Xu Wang was certain she had done something wrong. She was blasting the mice with blinding light to study how a specific gene affected the animals’ response to eye injury. All the mice were given the drug tamoxifen. Half were engineered to respond to the drug by disabling the gene — a step that would protect their eyes. The control mice, with all genes...
