New research compares environmental costs of livestock-based foods Trust me, no one loves a nice, big, juicy steak more than me and while I have no immediate plans of becoming a vegetarian, I am a little concerned about the resources and costs it takes to produce the proteins of our favorite meals. From the land that is used by livestock to the supplies and energy it takes to raise these animals for our consumption, it is evident that environmental resources take a toll. But what is the real cost? New research at the Weizmann Institute of Science, conducted in collaboration with scientists in the US, calculates these environmental costs and compares various animal proteins to give a multi-perspective picture of what resources are really being used.
Devil Rays are deep divers! Thought to dwell mostly near the ocean's surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and international colleagues reveals that these large and majestic creatures are actually among the deepest-diving ocean animals.
"So little is known about these rays," said Simon Thorrold, a biologist at WHOI and one of the authors of the paper, published July 1, 2014, in the journal Nature Communications. "We thought they probably travelled long distances horizontally, but we had no idea that they were diving so deep. That was truly a surprise."
Chinese Tesla owner's unique solution to range anxiety Chinese businessman Yi Zong decided to install charging stations himself after he purchased his Tesla earlier this year. He realized that charging his vehicle would be a problem in China because, well, there are few stations in that country. Zong installed recharging facilities on his own dime, or yuan as the case may be, in 16 cities between Beijing and his home in Guangzhou — a 3,573-mile corridor.
Zong, one of the first Chinese owners of the Model S, calls his project the country’s "first electric-charging road," according to a report at Caixin Online, a Beijing-based media group.
Obama allocates funds to help communities build climate adaptation More extreme droughts, floods and wildfires – these are just some of the impacts of climate change that won't just occur in the distant future to our great-great grandchildren, but are happening now. To address the changing climate's current effects on communities in the U.S., President Barack Obama announced a plan to strengthen national infrastructure and help cities, states and tribal communities better prepare for and recover from natural disasters.
What do volcanos look like deep underground? By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier's deep volcanic plumbing and partly molten rock that will erupt again someday.
"This is the most direct image yet capturing the melting process that feeds magma into a crustal reservoir that eventually is tapped for eruptions," says geophysicist Phil Wannamaker, of the university's Energy & Geoscience Institute and Department of Civil and Environmental Engineering. "But it does not provide any information on the timing of future eruptions from Mount Rainier or other Cascade Range volcanoes."
