We summarize the week's scientific breakthroughs every Thursday.
- Animals
This caterpillar wears the body parts of insect prey
Dubbed the “bone collector,” this caterpillar found on a Hawaiian island disguises itself while stalking spider webs for trapped insects to eat.
- Animals
Bats wearing tiny mics reveal how the fliers avoid rush hour collisions
As thousands of bats launch nightly hunting, the cacophony of a dense crowd should stymie echolocation, a so-called “cocktail party nightmare.”
- Animals
The story of dire wolves goes beyond de-extinction
Some question whether the pups are really dire wolves, or just genetically tweaked gray wolves. But the technology could be used to help at-risk animals.
- Earth
More details about the Myanmar earthquake are emerging
A phenomenon called liquefaction, which causes the ground to slump like quicksand, led to significant damage after the Myanmar earthquake. The risk of aftershock remains high.
- Plants
Watch live plant cells build their cell walls
Imaging wall-less plant cells every six minutes for 24 hours revealed how the cells build their protective barriers.
- Physics
Calls to restart nuclear weapons tests stir dismay and debate among scientists
Many scientists say “subcritical” experiments and computer simulations make nuclear weapons testing unnecessary.
- Animals
You might be reading your dog’s moods wrong
A dog's physical cues often take a back seat to environmental ones, skewing humans' perceptions, a small study suggests.
- Neuroscience
Parrots and humans share a brain mechanism for speech
Brain activity in vocalizing budgerigar parrots showed a pattern that harkened to those found in the brains of people.
- Animals
Narwhals may use their iconic tusks to play
Videos show narwhals using their tusks in several ways, including prodding and flipping a fish. It’s the first reported evidence of the whales playing.
- Science & Society
It’s ‘personal.’ What the Stand Up for Science rally meant for attendees
Stand Up for Science rallies in Washington, D.C., and across the United States drew crowds of people worried about cuts to scientific funding.
- Physics
The sound of clapping, explained by physics
The “Helmholtz resonator” concept explains the frequencies of sound produced by clapping the hands together in different configurations.
- Animals
In a first, zebra cams reveal herds on the move with giraffes
Six zebras wore video cameras attached to collars, capturing the equines’ daily life. Sticking with giraffes may let the two species protect each other.
