Leopards Are More Vulnerable Than Believed, Study Finds

Credit Steve Winter/National Geographic Leopards are reclusive and known for their ability to adapt, traits that have led some wildlife biologists to assume that the animals remained relatively abundant in the wild.But a study published Wednesday suggests that leopards have lost as much as 75 percent of their historical range since 1750. At that time, the big cats roamed over about 13.5..>> view originalUAE will Build an Artificial Mountain To Bring More Rain
The man-made mountain will change weather patterns and increase rainfall United Arab Emirates is not new to mega structures. From Burj Khalifa, the tallest building in the world, to Palm Jumeirah, world’s largest manmade island, to Dubai Marina, world’s largest artificial canal city, construction of various gigantic structures have been witnessed over the years. Soon another mammoth structure could make its way into the list.UAE is planning to build an artificial mountain, which will be large e..>> view originalOceans Are Running Out Of Oxygen, Says Study
While a small section of society continues to deny the effects of climate change, a new study suggests that the phenomenon is causing oxygen levels to decrease in our oceans. Evidence continues to mount that climate change caused by global warming is a huge threat to the future of our planet and life as we know it. The effects of climate change run so deep that it is causing oxygen depletion in the ocean. Worrying trend set to worsen ocean conditions Climate scientists have warned that unles..>> view originalGame of bones? Ice Age European drama uncovered by 51 genomes
A new study sheds light on the genetic composition of early modern humans, who arrived in Europe about 45,000 years ago and lived for millennia alongside our extinct cousins, the Neanderthals.In analyzing DNA from the ancient bones – 45,000 to 7,000 years old – of 51 of these prehistoric humans, an international team of scientists found evidence of population turnover and waves of migration during European prehistory, driven by advancing and retreating glaciers. The last ice age peaked between ..>> view originalHow IBM's new five-qubit universal quantum computer works
The five qubits in IBM's quantum computer.IBM In the wee hours of Wednesday morning, IBM gave an unwary world its first publicly accessible quantum computer. You might be worried that you can tear up your passwords and throw away your encryption, for all is now lost. However, it's probably a bit early to call time on the world as we know it. You see, the whole computer is just five bits. This might sound like some kind of publicity stunt; maybe it's IBM's way of clawing some attention back f..>> view originalReported Breakthrough in Growing Embryos in Vitro Could Raise Ethical Issues for Research

PISCATAWAY, N.J. (Thomson Reuters Foundation) - A United Nations panel of scientists seeking ways for nations to limit global warming to 1.5 degrees Celsius should not dissuade governments from concentrating on bleaker scenarios of higher temperatures as well, its former chief said on Wednesday.Nations should be considering the potential impact of temperature rises of much as 4 degrees Celsius (7.2 Fahrenheit), said Robert Watson, former head of the U.N. Intergovernmental Panel on Climate Chan..>> view originalHumans Paid for Bigger Brains With Gas-Guzzling Bodies
Evolution works on a strict energy budget. Each adaptation burns through a certain number of calories, and each individual can only acquire so many calories in the course of a day. You can’t have flapping wings and a huge body and venom and fast legs and a big brain. If you want to expand some departments, you need to make cuts in others. That’s why, for example, animals that reproduce faster tend to die earlier. They divert energy towards making new bodies, and away from maintaining their own...>> view originalMeteor Shower Spawned by Halley's Comet Peaks This Week
