We summarize the week's scientific breakthroughs every Thursday.
- Animals
A new orange and black bat species is always ready for Halloween
A new species from the sky islands of Africa’s Nimba Mountains shows bats’ colorful streak.
- Life
Giant worms may have burrowed into the ancient seafloor to ambush prey
20-million-year-old tunnels unearthed in Taiwan may have been home to creatures that ambushed prey similar to today’s monstrous bobbit worms.
- Animals
Some bacteria are suffocating sea stars, turning the animals to goo
For years, researchers thought an infectious pathogen was behind sea star wasting disease. Instead, bacteria deplete the starfishes’ oxygen.
- Life
Monitor lizards’ huge burrow systems can shelter hundreds of small animals
Two species of Australian monitor lizards dig nests four meters deep. Now scientists reveal that the burrows are home to far more than their creators.
- Animals
Some electric eels coordinate attacks to zap their prey
Electric eels were thought be to solitary hunters, until researchers observed over 100 eels hunting together, releasing coordinated electric attacks on corralled prey.
- Plants
Rats with poisonous hairdos live surprisingly sociable private lives
Deadly, swaggering rodents purr and snuggle when they’re with mates and young.
- Paleontology
Newborn megalodon sharks were larger than most adult humans
Preserved pieces of backbone suggest that megalodon sharks were about 2 meters long at birth.
- Neuroscience
Mice may ‘catch’ each other’s pain — and pain relief
Healthy mice mirror a companion’s pain or morphine-induced relief. Disrupting certain connections in the brain turns off such empathetic behaviors.
- Animals
Brown tree snakes use their tails as lassos to climb wide trees
A never-before-seen climbing technique could inspire the creation of new serpentine robots to navigate difficult terrains.
- Climate
Ocean acidification may make some species glow brighter
Ocean organisms use bioluminescence for hunting, defense and more. A new analysis shows that declines in water pH might change who glows and how much.
- Genetics
Some identical twins don’t have identical DNA
Mutations arising early in development may account for genetic differences between identical twins.
- Genetics
Plague may have caused die-offs of ancient Siberians
DNA suggests that the deadly bacterium that causes the plague reached northeast Asia by 4,400 years ago.
