This Week in the Future, October 30- November 6 :   Baarbarian

The future continued to unfold before us this week, and it's been quite a week indeed.

A whale’s skin is easily glommed up with barnacles, algae, bacteria and other sea creatures, but sharks stay squeaky-clean. Although these parasites can pile onto a shark’s rippled skin too, they can’t take hold and thus simply wash away. Now scientists have printed that pattern on an adhesive film that will repel bacteria pathogens from hospitals and public restrooms.

When humans eventually travel to Mars and beyond, they'll have plenty to worry about along with the discomforts of eating freeze-dried food and drinking their own urine. A new report says they will probably be really sick, to boot -- from flare-ups of E. coli, chicken pox or staph infections.

A host of microscopic stowaways could make interplanetary voyagers sick, especially because human immune systems are compromised in space, and because bacteria seem to thrive in micro- or zero-gravity environments.

The ACLU is one step closer to getting patents on human genes banned after a federal court today ruled that its lawsuit can continue. The defendants (The US Patent and Trademark Office and the owners of the BRCA breast cancer gene patent) had asked the court to dismiss the case.

About 20 percent of the human genome is currently patented, including genes associated with many diseases such as breast cancer and Alzheimer's. The patents mean that outside researchers need permission to study the genes and that tests can be astronomically expensive. (The test for BRCA is about $3,000.)

Implantable electronics like pacemakers are old hat, but these kinds of implants are limited by the fact that they must be encased to protect them from the body, and vice versa. But in the quest to make our bodies ever more bionic, researchers have now developed implantable silicon-silk electronics that almost dissolve completely inside the body, leaving behind nanocircuitry that could be used for improved electrical interfaces for nervous system tissues or photonic tattoos that display blood-sugar readouts on the skin’s surface.

In 2008, the International Association of Athletics Federations (IAAF) banned double amputee Oscar Pistorius from racing in the 2008 Summer Olympics. Later that same year, the ban was reversed. The back and forth centered on Pistorius' specially designed, spring-loaded, prosthetic legs. The IAAF argued that artificial legs designed especially for running gave Pistorius an unfair advantage against runners whose flesh-and-blood limbs didn't benefit from advanced engineering and space-age materials.
