Beef: It's What's For Dinner

The Kansas City Star has concluded a year long investigation of the beef industry, and the results may sicken you. Literally. (contains slaughterhouse image) To quote the Huffington Post article on the investigation: This is the true state of affairs . . . just four companies process more than 87 percent of the beef packed in the U.S., and take advantage of novel, money-saving techniques that significantly increase the risk of contamination by foodborne pathogens, leading to hundreds of preventable illnesses every year.

Eating the plate instead of the food

With the possible exception of the Nobel awards, physicists seem to get all the press these days, whether they're doing quantum level work at the LHC, or cosmology via the latest satellite data. Biologists, not so much. It's too bad, because Richard Lenski is running one of the great evolutionary experiments of our time, and it's producing interesting results. [more inside]

Liquid Hydrocarbons on Demand?

In September, a privately held and highly secretive U.S. biotech company received a patent for a genetically adapted E. coli bacterium that feeds solely on carbon dioxide and excretes liquid hydrocarbons. Joule Unlimited, co-founded by George Church, appears ready to forever alter the way we produce fuel. [more inside]

Gingers and daywalkers rejoice!

The human body is made up of more bacteria cells than human cells. Now, researchers at Harvard have isolated the genes responsible for producing amino acids that can block ultraviolet light and managed get E. coli bacteria to produce them too. Can I interest you in some sunblocking bacteria living on your skin?

It's what's for dinner

Ammonia-injected centerfuged fatty trimmings = pink slime + E. Coli. Eight years ago, federal officials were struggling to remove potentially deadly E. coli from hamburgers when an entrepreneurial company from South Dakota came up with a novel idea: injecting beef with ammonia.

Natural selection observed in a lab

In the 1980s, Richard Lenski hypothesized that his research team should be able to watch random mutations and natural selection taking place in a lab by observing a bacteria population over many generations. In 1988, beginning with a single bacterium, he started several replicate colonies. Recently, after 33,127 generations, his team has observed natural selection.

You Don't Poop Where You Eat

Taco Bell E. Coli Out break from... green onions? This is the second major outbreak of E. Coli from vegetables this year. Where does E. Coli come from? "One of the root words of the family's scientific name, "enteric", refers to the intestine, and is often used synonymously with 'fecal'."
