China's top weather scientist has made a rare official acknowledgement: climate change, he says, could have a "huge impact" on the country's crop yields and infrastructure.

Zheng Guogang, the head of China's meteorological administration, tells Xinhua news agency that China is already experiencing temperature increases that outpace those in other parts of the world.

As a result, China — the world's biggest emitter of greenhouse gases — faces a possible "ecological degradation," he says.

N. gardneri mushrooms grow at the base of young babassu palms in Brazil. A bland tan by day, the fungi emit an eerie green light by night.

For The Love Of Pork: Antibiotic Use On Farms Skyrockets Worldwide

Originally published on Sat March 21, 2015 2:21 am

Regions that produce the most pork and chicken also use the most antibiotics on farms. Hot spots around the world include the Midwest in the U.S., southern Brazil, and China's Sichuan province. Yellow indicates low levels of drug use in livestock; orange and light red are moderate levels; and dark red is high levels.
PNAS

Sorry bacon lovers, we've got some sad news about your favorite meat.

To get those sizzling strips of pork on your plate each morning takes more antibiotics than it does to make a steak burrito or a chicken sausage sandwich.

Pig farmers around the world, on average, use nearly four times as much antibiotics as cattle ranchers do, per pound of meat. Poultry farmers fall somewhere between the two.

Whatever lands you in the hospital or nursing home also puts you at risk for acquiring an infection, possibly one that's resistant to antibiotic treatment.

Staph infections are common problems in health care facilities, and many Staphylcoccus aureus bacteria are now resistant to drug treatment.

Chances are you've heard of MRSA, which is the kind of staph that isn't susceptible to methicillin, the antibiotic that used to be a silver bullet.

Interior Secretary Sally Jewell speaks in Anchorage, Alaska. The Obama administration is requiring companies that drill for oil and natural gas on federal lands to disclose chemicals used in hydraulic fracturing operations.

The Department of the Interior has unveiled new regulations on hydraulic fracturing operations that take place on federal lands, requiring companies using the drilling technique to ensure wells are safe and to disclose chemicals used in the process.

The rules change follows a more than three-year review process and will affect the 90 percent of oil and gas wells on federal lands that now use so-called fracking to extract oil and gas.

People throughout Europe, as well as parts of the Middle East, Russia, Africa, Asia and South America, got a stunning view of a partial solar eclipse Friday. A very few lucky ones at sea and in the high Arctic caught a glimpse of the same event as a total eclipse, as the moon passed in front of the sun.
