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.
- Genetics
Scientists Say: DNA sequencing
All of us have our own individual DNA. Now, scientists can determine what each individual strand is made of — a process called DNA sequencing.

End of Latin America’s Zika epidemic is in sight
A computer simulation suggests the Zika epidemic in Latin America is peaking and may not strike hard again for up to three decades.

GM mosquitoes cut rate of viral disease in Brazil
Adults males carrying the altered gene cannot father young that survive to adulthood. That’s when they suck blood — and can transmit disease.
- Animals
Scientists Say: Crepuscular
Day creatures are diurnal. Night creatures are nocturnal. Animals active at twilight get a special name.
- Climate
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.

Frigate birds spend months without landing
Frigate birds can fly non-stop for months. They stay in the air with the help of upward-moving airflows, a new study finds.
- Animals
Scientists Say: Venomous
A poison-arrow frog is poisonous, but a rattlesnake is not. What’s the difference? It’s how their poisons are delivered.
- Fossils
Parasites wormed their way into dino’s gut
Tiny burrows crisscross the stomach of a 77-million-year-old dinosaur fossil. These may be tracks left behind by slimy parasitic worms.

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.

Hormone affects how teens’ brains control emotions
Using scans of brain activity, scientists show that surging hormones drive where emotions get processed in a teen’s brain.
