Four-Fifths Of All Antibiotics In The US Go To Livestock
According to recent FDA data compiled by a Pew Charitable Trusts project, the amount appears to be growing while the government "dithers with voluntary approaches to regulation."

What's the Latest Development?
Last week, the FDA released a report summarizing the use of antimicrobial drugs, including antibiotics, in livestock production in 2011. The Pew Campaign on Human Health and Industrial Farming compared the FDA's data to that for human antibiotic use and discovered that almost four times as many pounds of antibiotics -- 29.9 million -- were given to healthy livestock as were given to sick people. Furthermore, as demonstrated in an infographic, the amount of antibiotics used for livestock has increased since 2003, while the amount used for humans has largely leveled off over the same time period.
What's the Big Idea?
In addition, the Pew campaign looked at the latest data from the FDA's National Antimicrobial Resistance Monitoring System (NARMS), which tests meat samples for pathogens. Writer Tom Philpott reports that based on this data, bacteria genera such as Salmonella and Campylobacter have become significantly resistant to one or more antibiotics over time. In the case of Campylobacter, about 95 percent of retail chicken products were contaminated, and of those, about half of the bacteria was resistant to tetracyclines.

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
