Lake Tahoe warming 15 times faster than long-term average
FILE - In this Aug. 24, 2015 file photo, a kayaker paddles along Zephyr Cove, the sight of the 19th Annual Lake Tahoe Summit in south Lake Tahoe, Nev. A new study says the average surface temperature of Lake Tahoe has risen faster over the last four years than any time on record - 15 times faster than the long-term warming rate over the past half century. The annual report issued by the UC Davis Tahoe Environmental Research Center says continued warm and dry conditions contributed to several..>> view originalOur Chemicals Are Killing Honey Bees' Sex Lives
If there’s a species that doesn’t need an unintentional dose of birth control, it’s the honey bee. A new study, however, suggests two common neonicotinoid insecticides are not only shortening the overall lifespan of male honey bees, known as drones, but also inhibiting their ability to produce viable sperm. The chemicals’ contraceptive effects, warn researchers from Switzerland’s University of Bern, could have “profound consequences for the health of the queen, as well as the entire colony.” ..>> view originalFact-checking Bill Clinton on Hillary's big climate change accomplishment
In detailing their much-scrutinized marriage and love story at the Democratic National Convention, former President Bill Clinton also took care to list his wife’s numerous legislative and foreign policy achievements. Among them: "She put climate change at the center of our foreign policy. She negotiated the first agreement ever — ever — where China and India officially committed to reduce their emissions." While Bill Clinton’s claim is largely accurate, he’s offering a rosy spin on the Copenhag..>> view originalWhy is Jupiter so darn hot? The roiling Great Red Spot may solve the mystery
Jupiter is hot, hot, hot – but it shouldn't be. And scientists now think they have caught a culprit red-handed.The gas giant is over five times farther from the Sun than Earth, but temperatures in the planet's upper atmosphere average about the same as those in our own upper atmosphere. So what is heating up Jupiter?The mysterious, roiling storm dubbed the Great Red Spot might be spewing heat, according to a study published Wednesday in the journal Nature. About 500 miles above the humongous sw..>> view originalNew Space Boots Vibrate to Help Astronauts Navigate

The low-gravity environment allowed him to leap from the lunar surface.

A team of scientists led by Southwest Research Institute (SwRI) made a puzzling observation while studying the size and distribution of craters on the dwarf planet Ceres. Ceres is the largest object in the tumultuous Main Asteroid Belt between Mars and Jupiter. Collision models predicted Ceres should have accumulated up to 10 to 15 craters larger than 400 kilometers (250 miles) wide, and at least 40 craters larger than 100 km (62 miles) wide. Instead, NASA's Dawn spacecraft found only 16..>> view originalTales of a lone wolf: Scientists find US has just one true wolf species
The gray wolf is North America's only native wolf species, a new study concludes, overturning common understanding – and government conservation classification – of America's fabled moon-howlers.Eastern and red wolves are actually the not-so-distant ancestors of gray wolves and coyotes, rather than their own species, according to a Princeton-UCLA study published in Science Advances Wednesday. The scientists behind the research are calling for the US Fish and Wildlife Service to rethink its plan..>> view originalDelta Aquarid Meteor Shower Peaks Tonight | The Weather Channel

Ape speech is surprisingly like our own
While science continues to uncover the many interesting ways animals communicate with each other, we humans have long considered ourselves distinct from our most recent ancestors, thanks to our powers of elocution. Our range of vocal abilities is unique; it evolved after human lineage split off from our ape relatives.Or so we thought.As it turns out, Rocky the Orangutan can control his voice, too.Research published Wednesday in the journal Scientific Reports demonstrates how Rocky, a resident o..>> view original
