We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Life
Video reveals that springtails are tiny acrobats
Poppy seed–sized cousins of insects, famed for wild escape leaping, right themselves in mid-falls faster than cats.
- Animals
Tree-climbing carnivores called fishers are back in Washington’s forests
Thanks to a 14-year reintroduction effort, fishers, or “tree wolverines,” are once again climbing and hunting in Washington’s forests after fur trapping and habitat loss wiped them out.
- Health & Medicine
This robotic pill clears mucus from the gut to deliver meds
A whirling robotic pill wicks mucus from the gut, allowing intravenous drugs such as insulin to be given orally, experiments in pigs suggest.
- Particle Physics
How ghostly neutrinos could explain the universe’s matter mystery
If neutrinos behave differently from their antimatter counterparts, it could help explain why our cosmos is full of stuff.
- Animals
Need to keep cockatoos out of your trash? Try bricks, sticks or shoes
In Sydney, humans may be in an escalating arms race with cockatoos. People are trying new tools to keep the pesky parrots out of their trash.
- Animals
Zoo gorillas use a weird new call that sounds like a sneezy cough
A novel vocalization made by the captive great apes may help them draw human attention.
- Life
Sea sponges launch slow-motion snot rockets to clean their pores
Sea sponges rely on a sneezing mechanism to clear their pores, using mucus to flush out debris. This mucus provides food for other marine life.
