Cool Jobs: Linking animal health to human health
Scientists who watch out for diseases in wild animals also can play a role in keeping people from getting sick.

Algae embedded in sea ice drive the Arctic food web
Scientists traced where zooplankton in the Arctic get their energy from. Many open ocean species rely on algae found in sea ice, which is disappearing.
- Climate
Scientists Say: Albedo
To measure how much light reflects off an object, scientists measure its albedo.

Something in plastics may be weakening kids’ teeth
The body can confuse some pollutants for a natural hormone. Researchers in France now find such pollutant exposures in childhood may lead cells to make defective tooth enamel.

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, animals adapt to city living
Cities have turned into experiments in evolution for both plants and animals, from the taste of clover to the stickiness of lizards’ toes.

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.

Helium discovery blows away shortage worries
Fears that the world may soon run out of helium have been set aside for now by the finding of a huge reservoir of the gas in East Africa.
- Earth
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.

Last year’s strong El Niño is gone. Next up: La Niña
The 2015 to 2016 El Niño was one of the three strongest on record. It’s now over. Climate experts now predict a La Niña is on its way.

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.
