Fossil of oldest octopus and vampire squid relative may reveal 10-armed past
A newly described fossil may be the oldest relative yet found of octopuses and vampire squids — although if it is a new species at all is disputed.
New children’s malaria treatment clears out infection in liver
Malaria can hide in the liver, causing relapse months or years later. Now, public health officials have a new treatment to prevent relapse for children under 16.
New breed of pig will provide organs for human transplantation
German researchers are breeding a new type of pig that’s been genetically modified to have organs ideal for human transplantation.

Molecular Attraction plans to kill mosquitoes transmitting malaria by tricking them into drinking beet juice “blood” laced with toxins.
Using robotic fish to harness the “ecology of fear”
To fight an invasive fish threatening Australia’s critically endangered freshwater natives, researchers are looking to robotic predators — and the “ecology of fear” they create.
Clues in woolly mammoth tusk reveal a lifetime of travels
Researchers have reconstructed the life of a woolly mammoth that lived more than 17,000 years ago by deciphering clues hidden in his tusk.
Series | Just Might WorkHow robots could end animal captivity in zoos and marine parks
Could robotic dolphins help marine parks become more humane spaces where people can learn about and connect with nature?

Animal conservationists plan to attempt the largest elephant rewilding ever, flying an entire herd from a U.K. zoo to Kenya to be released.
Hippos in tracking study unexpectedly contract anthrax
A study into the movement of hippos led to new research on anthrax outbreaks when some of the animals wearing GPS trackers contracted the disease.
Snails wearing smallest computer solve extinction mystery
The world’s smallest computer was used to figure out why one species of snail survived a situation that pushed more than 50 others into extinction.
Microscopic animals revived after 24,000 years in permafrost
A multicellular animal called the bdelloid rotifer has used cryptobiosis to survive in the Siberian permafrost for at least 24,000 years.
Genes show which animals will adapt to climate change
Some fish, such as the threespine stickleback, can respond to dramatic seasonal changes very quickly — genome sequencing reveals why.
Birds, frogs, and reptiles use sound to “program” embryos
Sound appears to play a larger role in animal development than previously thought, affecting how a variety of species prepare for life outside the womb or egg.
Bat-inspired sound location tech could allow drones to fly solo
Inspired by bat’s ears, researchers at Virginia Tech have created a device capable of pinpointing sound location more accurately than other tech — or our ears.
Fireflies may use “musical armor” to keep bats at bay
Fireflies’ primary aposematic signal that they’re poisonous may not be visible to bats, so the bugs appear to have a second, sound-based warning sign.
