Bumphead parrot fish declare their arrival with a crunch
Months of swimming with the coral-biter bumpheads exposes the animal’s extreme digestion and also a conservation dilemma.

Seeing past the jellyfish sting
Jellies don’t get nearly as much love as their cousins, the corals, but they deserve credit for providing homes to some creatures, dinner to others and more. They’re an integral part of the oceans.

Test drug stops Marburg virus in monkeys
Using a nano-size piece of RNA, scientists have stopped Marburg virus in monkeys.
- Animals
These lizards may be able to learn from each other
An experiment with skinks provides the first evidence of social learning in lizards.
- Oceans
Viruses might tame some algal blooms
The rapid demise of a giant, carbon-spewing algal bloom points to the influence of viral wranglers.
- Animals
Hummingbirds evolved a strange taste for sugar
While other birds seem to lack the ability to taste sugar, hummingbirds detect sweetness using a repurposed sensor that normally responds to savory flavors.
- Ecosystems
Lake under Antarctic ice bursts with life
Abundant microbes thrive in subglacial lakes deep under the Antarctic ice sheet.
- Health & Medicine
Experimental drugs and vaccines poised to take on Ebola
The use of experimental drugs and vaccines against Ebola may turn the tide against an outbreak in Africa that has defied efforts to control it.
- Animals
Orcas and other animals may speak with complexity
From finches to orangutans, animal vocalizations may be more complex and not as distant from the structure of human language as previously thought.
- Genetics
Long before Columbus, seals brought tuberculosis to South America
Evidence from the skeletons of ancient Peruvians shows that seals may have brought tuberculosis across an ocean from Africa.
