Like humanity, the earth's magnetic pull seems at least partly birthed by Africa.
After studying deep-core sediment and creating maps of the Chesapeake region stretching back millions of years, researchers say that a long-held theory that Washington, D.C. is sinking faster toward the sea than most other coastal U.S. cities, and an existing theory that ice-sheet melt contributed to this--are both true.
June 29 is Global Tiger Day--a recognition of the big cats that began in 2010, after a global summit on the tiger in St. Petersburg, when tiger numbers worldwide were estimated at 3200. With poaching as tigers' biggest threat, and some countries unaware of their tiger numbers, can we solidify numbers soon, considering that three of tigers' nine subspecies are now extinct?
In many parts of the world, education is the #1 factor associated with awareness of climate change. But there are regional distinctions, and countries vary in terms of why people do or don't know the word and phenomenon. More here from a global poll done by researchers from Yale, Columbia, Utah State, Princeton, U-Mass-Amherst, and Academica Sinica in Taiwan.
Are the world's deserts holding more carbon than all the plants in the world?
Editorial: While it's not a pit of tar in a Los Angeles park, it may be nearly as good in terms of providing a predator record of the Jurassic period. Paleontologists will continue to study this predator pit in Utah, first explored in 1928. Today they're using new technology, photogammetry.
A postage-stamped size pollinator with silvery blue wings, first found by Lolita author Vladimir Nabokov, the Karner blue is benefiting from habitat restoration and other programs. What's it take to bring back a species?
Protecting African elephants may become easier with intrepid sniffer dogs, recently graduated from a training program in Africa. They're being installed in which cities' ports?
The kiwi bird is a flightless wonder, incredibly iconic and recognizable to even the most ignorant of bird watchers. Now, more than century after it was academically studied for the first time, scientists have successfully sequenced the animal's entire genome, and what they have found brings a whole new level of understanding for why they evolved as uniquely as they did.
Sixty-six million years ago, a massive asteroid struck Mexico's Yucatán Peninsula. As a result, the Earth changed forever, spelling the end of the dinosaurs and ushering in a new age where other animals could flourish. Now new research has revealed that it wasn't mammals who inherited the Earth, but fish.
Jutting out of rock in a hiking area of Alaska's Talkeetna Mountains, a fossil-finder recently ran across the bones of an ancient, long-necked swimmer.
It turns out that trematodes and other parasitic flatworms live in larger numbers in temperate regions, contrary to the global norm of greater biodiversity in warm temperatures.
Mangroves decrease the force of tides with their net-like roots, but they also help build estuarial channels and just plain survive in times of rising water.
Finches that experienced stress hormones in food at a young age chose social networks outside of their immediate family, and didn't imitate parents' ways. Will their somewhat random socializing factor into the spread of bird flu?
