Scientists have finally cracked a 41-year-old mystery about an ancient eggshell from a large, extinct terrestrial bird with a demonic nickname. In 1981, researchers in Australia discovered the charred remnants of numerous eggs from several cooking fires used by prehistoric humans, dating to about 50,000 years ago. Some of the eggs were identified as those … Read more
The “secret code” the brain uses to create a key type of memory has finally been cracked. This type of memory, called working memory, is what allows people to temporarily hold on to and manipulate information for short periods of time. You use working memory, for example, when you look up a phone number and … Read more
Salt crystals from Central Australia hold ancient microorganisms that became trapped 830 million years ago, new research finds. And there’s a chance that some of the microorganisms might still be alive. The single-celled organisms are locked in tiny fluid pockets — smaller than the width of a human hair — in halite, or salt, from … Read more
An area of Pluto that researchers think was formed from the eruption of ice volcanoes is unique on the dwarf planet and in the solar system, a new study suggests. NASA’s New Horizons mission, which launched in 2006, took detailed photos of the surface of Pluto, a dwarf planet and the largest object in the … Read more
The days of invasive crazy ants — whose supercolonies can support millions upon millions of the fierce insects — may be numbered. That’s because a deadly fungus that uses spring-loaded harpoonlike barbs to pierce the ants’ gut cells is wiping out their colonies across the Southeastern United States. That’s not a bad thing. Tawny crazy … Read more
Researchers in the U.K. have developed a way to reverse the aging process in skin cells, turning back the biological clock by about 30 years. De-aging cells has become increasingly common in the last decade, with researchers reprogramming multiple mouse, rat and human cell types. But never before have cells been de-aged by so many … Read more
The unicorn is one of the most famous mythical creatures, often depicted as a white horse with a spiraling horn erupting from its forehead. It’s not hard to imagine a horse with a horn, and for much of the mythical creature’s history, people thought it actually existed. But where did this myth come from? Unicorn-like … Read more
Plastic-eating bacteria could help to one day tackle some of the 14 million tons of plastic that is offloaded into our oceans every year. Plastic pollution leads to severe impact on marine ecosystems and can affect human health. For example, once plastic enters the ocean it can suffocate and entangle animals, according to the International … Read more
Ancient trees, the venerable sentinels of forests, may preserve genetic diversity that helps woodlands thrive for thousands of years, a new study suggests. In a typical deciduous forest, the oldest of the old trees — many of which were standing during the First Crusade — can act almost like time-travelers, representing the forest as it … Read more
An experimental vaccine successfully eliminated aging cells from the bodies of mice, helping to prolong the rodents’ lives and reverse some signs of age-related disease. The researchers say the experiment is a step on the road to a similar vaccine for humans, but could it really work? “I think the data was extremely strong … … Read more
