Shrimp on treadmills? Some science only sounds silly
Research that may seem silly, at first glance, often has a rewarding aim. Here are some examples.
- Ecosystems
Underwater meadows appear to fight ocean germs
The seagrasses that sway in coastal currents are more than aquatic groundcover. They can reduce harmful bacteria that might otherwise sicken neighboring animals, new data show.
- Animals
Under blanket of ice, lakes teem with life
Life under frozen lakes is vibrant, complex and surprisingly active, new research finds. In fact, some plants and animals can only live under the ice. But with climate change, will that continue?

Food-like smell on plastic may lure seabirds to eat it
When plastic smells like supper, seabirds and other animals can be fooled into thinking it is food.

New date for U.S. arrival of the AIDS virus
A new study shows that HIV started circulating at least a decade earlier than previously realized.

Beaches can be a germy playground
Infectious microbes can flourish on sandy beaches. Scientists are now exploring how to find and monitor these hotspots for pollution that can make vacationers sick.

Creative ways to help coral reefs recover
Coral reefs are under siege from threats ranging from climate change to explosives. But scientists are developing ways to rebuild reefs before they disappear.

Water sensor quickly detects algal poison
A new sensor can detect poisons from harmful algae within minutes so that drinking-water plants can start timely treatments.
- Animals
Giant slugs snack on baby birds
When they accidentally run into bird nests sitting on the ground, some slugs help themselves to a free, easy meal of bird chicks.

Mouth germs team up to boost disease risk
The oxygen given off by harmless mouth bacteria can help disease-causing invaders grow strong and flourish.

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.
- Ecosystems
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.
