Discovering the power of placebos
If you take a fake pill and expect to feel better, you may. Researchers are learning how this placebo effect works and how to use it to help patients.

Headphones or earmuffs could replace needles in some disease testing
A new system that uses earmuffs to collect gases coming out the skin could help doctors diagnose a variety of diseases, scientists say.

Endangered or just rare? Statistics give meaning to the head counts
Whether studying tiny birds or massive whales, researchers collect a lot of data. The field of statistics helps them make sense of those data.
- Chemistry
Lots of makeup may contain potentially harmful ‘forever chemicals’
Hints of PFAS compounds have turned up in about half of tested makeup products. Waterproof mascaras and lipsticks were very likely to contain them.

Will we all need COVID-19 booster shots?
Experts say not yet, but booster vaccines may be coming as new SARS-CoV-2 virus variants keep emerging.

A common antibiotic might save some sick corals
The antibiotic amoxicillin stopped tissue death in corals for at least 11 months after treatment.
- Agriculture
New technologies might help keep drought-prone farms green
After learning how much damage drought can do to crops, two teens designed ways to detect a thirsty plant and make sure it gets enough water.

No animal died to make this steak
The ribeye steak is the first of its kind, and the latest in a growing list of meats printed with a 3-D bioprinter instead of being harvested from an animal.
- Ecosystems
Analyze This: Invasive species cost the world billions each year
A new study estimates that invasive species have cost the world more than $1 trillion since 1970. That’s almost certainly an underestimate.

New device gets power from 5G signals grabbed from the air
A new way to harvest electricity relies on a tiny array of antennas and a lens. Together, they collect and focus 5G signals coming from any direction.
