We summarize the week's scientific breakthroughs every Thursday.
- Math
Dense crowds of pedestrians shift into surprisingly orderly lines. Math explains why
New research into collective behavior adds to decades of study on the wisdom of crowds.
- Animals
These transparent fish turn rainbow with white light. Now, we know why
Repeated structures in the ghost catfish’s muscles separate white light that passes through their bodies into different wavelengths.
- Physics
Static electricity helps parasitic nematodes glom onto victims
The small electric charge generated by a moving insect is enough to affect the trajectory of a parasitic nematode’s leap so it lands right on its host.
- Life
Honeybees waggle to communicate. But to do it well, they need dance lessons
Young honeybees can’t perfect waggling on their own after all. Without older sisters to practice with, youngsters fail to nail distances.
- Neuroscience
Scientists have mapped an insect brain in greater detail than ever before
Researchers have built a nerve cell “connectivity map” of a larval fruit fly brain. It’s the most complex whole brain wiring diagram yet made.
- Cosmology
Astronomers spotted shock waves shaking the web of the universe for the first time
Studying these elusive shock waves could give scientists a better look at the mysterious magnetic fields that permeate the cosmic web.
- Animals
The fastest claw in the sea belongs to young snapping shrimp
When juveniles snap their claws shut to create imploding bubbles, they create the fastest accelerating underwater movements of any reusable body part.
- Health & Medicine
A new treatment could restore some mobility in people paralyzed by strokes
Electrodes placed along the spine helped two stroke patients in a small pilot study regain control of their hands and arms almost immediately.
- Health & Medicine
3-D maps of a protein show how it helps organs filter out toxic substances
Images of LRP2 in simulated cell environments reveal the structural changes that let it catch molecules outside a cell and release them inside.
- Materials Science
These shape-shifting devices melt and re-form thanks to magnetic fields
Miniature machines made of gallium embedded with magnetic particles can switch between solid and liquid states.
- Animals
These adorable Australian spike-balls beat the heat with snot bubbles
An echidna’s snot bubbles coat the spiny critter’s nose with moisture, which then evaporates and draws heat from the sinus, cooling the blood.
- Life
Long genital spines on male wasps can save their lives
A male wasp’s genital spines can save his life in an encounter with a scary tree frog, a new study shows.
