ENVIRONMENT & CLIMATEThroughout human history, people have utilized caves for protection from the elements, as safe havens from predators, and as canvases to display beautiful works of art. Now, a group of scientists from Vanderbilt University are using caves to learn about weather patterns in the past. And what they're discovering may provide insight into our planet's future climate.
Many species of snakes and lizards are able to change color, which helps them avoid detection, regulate their body temperature, and choose mates. But new research on panther chameleons shows that their colorful hides may not only aid in their survival, but might be concealing a range of species never before imagined.
If the battle of the sexes was fought by mosquitoes, it would already be over. Researchers from Virginia Tech's Fralin Life Science Institute has discovered that male mosquitoes aren't relevant at all, at least in the realm of transmissible diseases.
A part of Antarctica that scientists once thought to be safe from climate change is now showing signs of instability, and the loss of this ice could lead to the rising sea levels around the world.
In March 2014, the U.S. Fish and Wildlife Service set aside just over 1,000 acres of land straddling the U.S. and Mexican border in an effort to bolster the rapidly dwindling numbers of jaguars. This beautiful spotted cat, who once roamed from Argentina in South America, all the way up to the Grand Canyon in Arizona, has now been practically wiped out in the United States. But that is irrelevant to the angry ranchers who believe providing room for the cats was "unlawful, arbitrary, and capricious."
Antarctica is a truly massive continent. At over 5 million square miles, the whole of the US could fit securely within its borders. It boasts the highest, driest, coldest, and windiest landscape of all seven continents. And the fact that it is losing ice is nothing new. It's the rate at which parts of the continent are melting that is raising new concerns.
She was dressed in a knee-length skirt and a short woolen blouse when she was buried in an earthen mound in southern Denmark. She was only a teenager when she died. Her small body was wrapped in a blanket and placed in an ox hide-lined coffin made of oak. Beside her, tucked within a small cloth sack, were the cremated remains of a six-year-old child. Now, over 3,000 years later, scientists are able to trace the young girl's journey across an ancient landscape.
The long relationship between humans and dogs has just been pushed back by tens of thousands of years, thanks to a small piece of rib bone found during an expedition to the far northern reaches of Siberia. And the genetics show that dogs split from wolves much earlier than we once believed.
If you're going to study something as vast as the world's oceans, it helps if you have a large cadre of scientists to sift through the data. And that's just what an international research team, led by University of Arizona scientists, have done. They are rolling out the results of a three-year expedition in which they cataloged over 150,000 tiny ocean creatures, most of which are brand new discoveries.
May 22nd is the UN's International Day of Biological Diversity. This year's theme: Biodiversity for Sustainable Development. But instead of making little Pinterest planet Earth cupcakes or watching a movie about wildlife, why not get involved with National Geographic's Great Nature Project and have a real impact contributing to the scientific record?
In 2012, a team of paleontologists were scouring the rocky shores of what is today the small island of Sucia, located within Puget Sound, between Washington State and Vancouver Island. On the hunt for prehistoric shells, they inadvertently stumbled upon the bone of a creature never known to have ranged that far north - a dinosaur.
BP has begun to settle claims related to the 2010 Deepwater Horizon oil spill with Halliburton and Transocean. This means that as to Halliburton and Transocean only (the litigation is ongoing) the battle is over. The long-term in court battle has centered upon the human costs of the offshore well disaster, which included the deaths of 11 workers. The overall impact of the disaster has been sobering for the scientific community as well; the Deepwater disaster has thus far been the largest offshore oil spill in US history.
Researchers from the University of California, Santa Barbara have discovered that the octopus, uniquely adept with camouflage, can "see" with its skin. The study found that the California two-spot octopus can sense light using light-sensitive proteins, similar to those found in eyes, in its skin.
Armed with a high-powered 500 Nitro Express rifle and a CNN camera crew, Texan Corey Knowlton ended his three-day trek through the dusty plains of Namibia by doing what he had travelled over 8,000 miles to do: shoot and kill a black rhino.
Officials from the small fishing village of Taiji, in Central Japan, remain defiant amidst protests that label their dolphin hunts as cruel. Despite international outcry, the slaughter continues.
