- Genetics
A gene-based therapy partially restored a blind man’s vision
Light-activated proteins inserted in eye nerve cells and special goggles help the man, who lost his sight due to retinitis pigmentosa, see objects.
- Animals
Urchin mobs team up to butcher sea stars that prey on them
Urchins are important herbivores in nearshore ecosystems, but are not strict vegetarians, with hunger that extends even to munching predatory nemeses.
- Climate
‘Tree farts’ contribute about a fifth of greenhouse gases from ghost forests
Greenhouse gases from dead trees play an important role in the overall environmental impact of ghost forests, a new study suggests.
- Animals
Mammal brains may use the same circuits to control tongues and limbs
When mice drink water, they make corrective motions with their tongues that resemble similar adjustments made by primates when they grab for objects.

European fire ant chemicals may send spiders scurrying away
Black widows and some other common spider species avoid spaces where fire ants once roamed, suggesting the insects could inspire a spider repellent.
- Animals
The U.S.’s first open-air genetically modified mosquitoes have taken flight
After a decade of argument, Oxitec pits genetically modified mosquitoes against Florida’s spreaders of dengue and Zika.

Elephants are dying in droves in Botswana. Scientists don’t know why
Some type of pathogen may be behind the recent deaths of 39 elephants, a new wave that follows 350 deaths last summer.
- Neuroscience
Brain implants turn imagined handwriting into text on a screen
A person who was paralyzed from the neck down was able to communicate, thanks to brain-to-text technology.
- Neuroscience
Scientists remotely controlled the social behavior of mice with light
New devices — worn as headsets and backpacks — rely on optogenetics, in which bursts of light toggle neurons, to control mouse brain activity.
- Animals
A common antibiotic slows a mysterious coral disease
Applying the antibiotic amoxicillin to infected lesions halted tissue death in corals for at least 11 months after treatment.
- Neuroscience
Mild zaps to the brain can boost a pain-relieving placebo effect
By sending electric current into the brain, scientists can enhance the pain-relieving placebo effect and dampen the pain-inducing nocebo effect.
- Paleontology
T. rex’s incredible biting force came from its stiff lower jaw
T. rex could generate incredibly strong bite forces thanks to a boomerang-shaped bone that stiffened the lower jaw, a new analysis suggests.
