Even As MERS Epidemic Grows, The Source Eludes Scientists

Since emerging last year in the Middle East, a mysterious virus has infected at least 132 people and killed 58. But it’s still unknown how people get infected. A genetic analysis now suggests that animals may have repeatedly infected people with the deadly virus.

Inside The Beef Industry’s Battle Over Growth-Promotion Drugs

Beta agonists, a class of drugs widely fed to cattle and hogs to make them put on weight faster, are coming under increasing scrutiny. Reports suggest animals fed these drugs can seem reluctant to move — lethargic, unable to walk properly — and may die more often, too.

Eavesdropping On Nature Gives Clues To Biodiversity

Biologists who study the lives of animals can learn a lot simply by listening to them. The problem is that natural sounds can be far easier to record than to analyze. So scientists are working to automate the process with automated systems that do the identifying for them.
