Researchers have shared a paper including findings related to the observation of leprosy in wild chimpanzees, a reported first for the scientific community.

This Sponge Fossil May Be the Earliest Record of Animal Life
More than two decades ago, when Elizabeth Turner was still a graduate student studying fossilized microbial reefs, she hammered out hundreds of lemon-sized rocks from weathered cliff faces in Canada’s Northwest Territories. She hauled her rocks back to the lab, sawed them into 30-micron-thick slivers—about half the diameter of human hair—and scrutinized her handiwork under a microscope. Only in about five of the translucent slices, she found a sea of slender squiggles that looked nothing like the microbes she was after.
The Cardiovascular Secrets of Giraffes
To most people, giraffes are merely adorable, long-necked animals that rank near the top of a zoo visit or a photo-safari bucket list. But to a cardiovascular physiologist, there’s even more to love. Giraffes, it turns out, have solved a problem that kills millions of people every year: high blood pressure. Their solutions, only partly understood by scientists so far, involve pressurized organs, altered heart rhythms, blood storage — and the biological equivalent of support stockings.
Sharks Use the Earth’s Magnetic Field Like a Compass
EVERY YEAR, GREAT white sharks travel over 12,000 miles from South Africa to Australia, charting a nearly perfect straight line across the ocean. And every year, they turn around and travel back. There are no street signs to guide them and, for much of the journey, no stable landmarks by which they can set their course. Currents and water temperatures change. The sun sets at night, the stars disappear during the day. But the sharks carry on.
Elon Musk’s Neuralink Partner: ‘We Could Probably Build Jurassic Park If We Wanted To’
Fuck it. Let’s build Jurassic Park.
That’s what many have gleaned from recent comments by Max Hodak, one of the founders—alongside SpaceX and Tesla’s Elon Musk—of the neurotech company Neuralink.
How Do Animals Perceive Time?
I’m writing this on a Tuesday, at 2:26 p.m. Minutes ago, it was 9 a.m., or so it feels; back then, I was enjoying the delusion, refreshed each morning, that I’d accomplish what I needed to do today. I still might—there are hours left in the workday—but I’m wiser than I was when I woke up five hours ago: it’ll be 7pm soon, the day definitively in tatters. Another of Time’s routine beatdowns.
One advantage of being a cat, or a stingray, is not having to think about time this way (and, by extension, death). But are they entirely free from the temporal plane? Do they perceive it in any way? Do some species perceive it more acutely than others? For this week’s Giz Asks, we reached out to a number of experts to find out.
Oldest DNA Sequenced Yet Comes From Million-Year-Old Mammoths
Woolly mammoths were icons of the Ice Age. Starting 700,000 years ago to just 4,000 years ago, they trundled across the chilly steppe of Eurasia and North America. As ancient glaciers expanded across the Northern Hemisphere, these beasts survived the rapidly cooling temperatures with cold-resistant traits, a characteristic they came by not through evolution, as earlier thought. Woolly mammoths, a new Nature study finds, inherited the traits that made them so successful from a mammoth species closer to a million years old.
