New rules point scientists toward next-gen germ-killers
Shape and other features help germ-killing drugs make it through barriers to enter bacteria. Knowing how they do this could lead to more and better better antibiotics.

How Earth got its moon
How did our moon form? Scientists are still debating the answer. It may be the result of some one big impact with Earth — or perhaps many small ones.

Teen prints a device to help keep wounds dry
A Broadcom MASTERS finalist invented a sensor that goes off when a wound is too wet. This would alert a patient it’s time to change their bandage.

Arctic Sea could be ice-free by 2050
Everyone contributes to the melting of Arctic sea ice, and all are in danger of making summer ice disappear there completely by 2050, a new study finds.

Cool Jobs: Wet and wild weather
How’s the weather? Forecasts rely on scientists and engineers who collect and interpret data gathered on the ground, in the sky and way up in space.

Explainer: How to read brain activity
Electricity underlies the chattering of brain cells. Here’s how scientists eavesdrop on those conversations.

Explainer: What is epigenetics?
Epigenetics is the study of molecular “switches” that turn genes on and off. Tweak those switches and there could be big health consequences.
