Africa’s Most Endangered Carnivore Has Been Around For Over 1 Million Years
Africa is home to a rich array of carnivorous animals, from ferocious felids like lions and cheetahs to smaller creatures like foxes and mongoose. However, many such predators are also some of the continent’s most endangered – perhaps none more so than the highland-dwelling Ethiopian wolf (Canis simensis).

Neanderthal Children May Have Collected Fossils, Just Like Modern Kids Collect Stickers
A stash of 15 marine fossils has been found in a Neanderthal cave in northern Spain, indicating that the extinct hominids may have developed a passion for accumulating stuff in the same way that modern humans collect baseball cards, stamps, and memorabilia.

First Known Bird Extinction From Mainland Europe, North Africa, And West Asia Declared
The era of human-induced extinctions has a new victim: a migratory shorebird called the Slender-billed Curlew (Numenius tenuirostris) has been declared almost certainly deceased. Although 164 avian species are recognized to have gone extinct by the IUCN Red List, the curlew’s previous wide range makes its loss particularly disturbing. Like many migratory birds, the Slender-billed Curlew once […]
Why Does Metal Feel Colder Than Wood, Even When It’s Actually The Same Temperature?
Sometimes, it’s the everyday things that are most confusing. Things like, what are those weird dots on your windshield? Why is pink salt more expensive than the regular stuff?

How To Discover Life On Mars? In The Atacama, A New Method Holds One Key
There’s nowhere on Earth quite like the Atacama Desert. Literally: it exists in a basically unique meteorological void, rendering it all but devoid of water and home to almost no life at all.

The Freak Timing Of Our Uranus Visit May Have Misled Us For Years, The World’s Largest Coral Colony Has Been Discovered, And Much More This Week
This week, Ice Age Amazonian rock art has been interpreted and appears to depict shamans spiritually transforming into animals, a 35,000-year-old saber-toothed cub has been found mummified in permafrost, and the first amber fragments have been recovered from Antarctica, providing information about the continent’s ancient forests. Finally, we ask if animal testing is entirely necessary […]
How Do Tokamaks Work And Are They The Future Of Energy?
Vast amounts of money and brainpower in the effort to achieve sustained, controlled, nuclear fusion. Many designs have been proposed, and even tried, but tokamaks are comfortably the most popular. The name may be familiar, but not everyone knows what they are. What Is A Tokamak? Stars heat matter to such high temperatures that electrons […]
The Mediterranean Sea May Vanish Someday, Just As It Did Before

This research, conducted by researchers in China, is the first time that “neural coupling” between different species has been witnessed. Neural coupling is when the brain activity of two or more individuals aligns during an […]
Active Volcanoes Persisted On Far Side Of The Moon For 1.4 Billion Years
