Two plates which were coated with an antibiotic-resistant bacteria called Klebsiella with a mutation called NDM 1 and then exposed to various antibiotics are seen at the Health Protection Agency in north London March 9, 2011. The clear areas in the top left quarter of the plate on left show that the Klebsiella with NDM 1 was sensitive to the respective antibiotics tigecycline (manufactured by Pfizer under the trade name Tygacil) and colistin. For decades scientists have managed to develop new medicines to stay at least one step ahead of the ever-mutating enemy, bacteria. Now, though, we may be running out of road. Methicillin-resistant Staphylococcus aureus, commonly known as MRSA, alone is estimated to kill around 19,000 people every year in the United States -- far more than HIV and AIDS -- and a similar number in Europe, and other drug-resistant superbugs are spreading.

Researchers work on pork at the "Cloning & Genetic Engineering" section of the Beijing Genomics Institute in Shenzhen, southern China March 3, 2010. Some experts say the world is on the cusp of a "golden age" of genomics, when a look at the DNA code will reveal your risk of cancer, diabetes or heart disease, and predict which drugs will work for you. Yet the $3 billion international Human Genome Project, whose first phase was completed a decade ago, has not led to a single blockbuster diagnosis or product. Picture taken March 3, 2010.

A petri dish containing eggs harvested from cattle is seen during the second step of the cloning process in a cloning lab at ViaGen in Austin, Texas November 11, 2009. The U.S. Food and Drug Administration in 2008 approved the sale of food from clones and their offspring, stating the products are indistinguishable from that of their non-clone counterparts. The moves have stirred controversy about whether tinkering with nature is safe, or even ethical, prompting major food companies to swear off food products from cloned animals. But consumers are likely already eating meat and drinking milk from the offspring of clones, which are technically not clones, without even knowing it. Picture taken November 11, 2009.
