Animals get safe spots to cross the road — and car collisions drop
Over- and underpasses built for wildlife in Wyoming proved a success for both the animals and the humans traveling the roads.
- Environment
Deepwater Horizon oil spill caused months-long ‘dirty blizzard’
Pollution from the 2010 Deepwater Horizon oil spill accumulated on the seafloor for months after the leak was patched.

Morphine may make pain last longer
Instead of busting pain, morphine lengthened the duration of pain in rats with a nerve injury.
- Science & Society
Biologist Kate Rubins’ big dream takes her to the space station

Bacteria resistant to last-resort antibiotic appears in U.S.
For the first time in the United States, scientists have reported a patient infected with a strain of bacteria carrying the gene mrc-1, making it resistant to the last-ditch antibiotic colistin.
- Animals
Counting cats is hard, but we know the numbers aren’t good
Recent studies highlight the difficulty of counting big cats, but even imperfect counts show that these species are in trouble.
- Life
Fruit fly’s giant sperm is quite an exaggeration
Giant sperm, about 20 times a male fruit fly’s body length, could make the insects the champs of supersized sexual ornaments.
- Neuroscience
Alzheimer’s culprit may fight other diseases
A notorious Alzheimer’s villain may help bust microbes.

Women in sports are often underrepresented in science
More and more women are taking up recreational and competitive sports. But when it comes to exercise science, the studies don’t reflect that trend.
- Animals
Antibiotics in cattle leave their mark in dung
Treating cattle with antibiotics may have side effects for dung beetles, microbes and greenhouse gases.
- Animals
Snot could be crucial to dolphin echolocation
An acoustic model reveals that echolocation relies on mucus lined tissue lumps in the animal’s nasal passage.

For baby sea turtles, it helps to have a lot of siblings
After hatching, baby sea turtles must dig themselves out of their nest. This requires less energy if there are lots of siblings, a new study finds.
