Pollen-deprived bumblebees may speed up plant blooming by biting leaves
In a pollen shortage, some bees nick holes in tomato leaves that accelerate flowering, and pollen production, by weeks.

The oldest genetic link between Asians and Native Americans was found in Siberia
DNA from a fragment of a 14,000-year-old tooth suggests that Native Americans have widespread Asian ancestry.

Here’s a clue to how this tube worm’s slime can glow blue for days
Mucus oozed by a marine tube worm can glow for up to 72 hours. New results suggest that the light may sustain itself through some clever chemistry.

Saber-toothed anchovy relatives hunted in the sea 50 million years ago
Unlike today’s plankton-eating anchovies with tiny teeth, ancient anchovy kin had lower jaw of sharp spikes paired with a single giant sabertooth.

Blind people can ‘see’ letters traced directly onto their brains
Arrays of electrodes can trace shapes onto people’s brains, creating bursts of light that people can “see.”

New hybrid embryos are the most thorough mixing of humans and mice yet
Human-mice chimeras may usher in a deeper understanding of how cells build bodies.

A gene variant partly explains why Peruvians are among the world’s shortest people
A gene variant reduces some Peruvians’ height by about 2 centimeters, on average, the biggest effect on stature found for a common variation in DNA.

Tapirs may be key to reviving the Amazon. All they need to do is poop
Brazilian ecologist Lucas Paolucci is collecting tapir dung to understand how the piglike mammals may help restore degraded rain forests.

Some comb jellies cannibalize their young when food is scarce
Invasive warty comb jellies feast on their larvae after massive population booms in the summer deplete their prey from waters off of Germany.

A game based on Simon shows how people mentally rehearse new information
Signs of learning echo through people’s resting brains.

Warming water can create a tropical ecosystem, but a fragile one
Tropical fish in a power plant’s warm discharge disappeared with the plant’s shutdown, giving insight into ecosystems’ reaction to temperature shifts.
