Non-scents: Pollution can confuse pollinators’ sniffers
New research uses computers to predict how much longer it takes bees and other pollinating insects to sniff out lunch in a polluted environment.
- Plants
Climate closing the gender gap for this mountain flower
Among valerian plants, males like it hotter than the females do. So a warming climate has been speeding their migration up once-cool mountainsides.

Current coral bleaching event is the longest known
Heat stress has led to the longest coral bleaching event on record. Scientists now worry that global warming may make such prolonged crises more frequent.

Scientists Say: Plastisphere
As plastic floats in the ocean, it can acquire its own colony of microbes and algae. We call this ecosystem the plastisphere.

Volcanic rocks can quickly turn pollution into stone
A test program in Iceland injected carbon dioxide into lava rocks. More than 95 percent of the gas turned to stone within two years.

Teens use science to worm through plastic waste
Some beetle larvae can eat plastic, which might be good for our pollution problem. But which types eat the most can vary a lot, these young scientists find.

Catching ‘Dory’ fish can poison entire coral reef ecosystems
More than half of saltwater-aquarium fish sold in the United States may have been caught in the wild using cyanide, new data show.

Fighting big farm pollution with a tiny plant
Fertilizer runoff can fuel the growth of toxic algae nearby lakes. A teen decided to harness a tiny plant to sop up that fertilizer.

Concrete science
Teen researchers are exploring ways to strengthen this building material, use it for safety purposes and use its discarded rubble.

Zapping clouds with lasers could alter Earth’s climate
Scientists zapped ice crystals in a lab. They were exploring whether this approach might be used to break those crystals in clouds — potentially as a way to cool Earth’s fever.

‘Couch potatoes’ tend to be TV-energy hogs
Many government programs urge people to save electricity by using more efficient TVs. Here’s why these programs should target “couch potatoes.”

Common water pollutants hurt freshwater organisms
The germ killers we use and the drugs we take don’t just disappear. They can end up in the environment. There they can harm aquatic organisms, three teens showed.
