Once upon a time, prosthetic augmentation of a failing sense of hearing took the form of devices the size of a paperback book hung around one's neck and smallish headphones pumping amplified sound into the wearer's ears. As technology progressed and the sizes of components shrank to sub-surface mount form factors (for illustration please note the sizes of the 603 and 402 components) hearing aids shrank in size until they could be custom molded to fit snugly into one's ear canal. All of the benefit with very little of the mass or weight. Hand in hand with the miniaturization …

In the twenty-first century you'd be hard pressed to find a piece of every day kit that doesn't have a power cell of some kind running it. Cellphones, tablets, laptops, MP3 players... they all need to be plugged in periodically to recharge. Under optimal conditions they can go two or three days in between top-offs but sometimes that isn't practical. Additionally, rechargable power cells have a finite lifetime and start to run dry faster and faster after two or three hundred recharges. This next bit of tech makes me wonder... a research team at Virginia Tech has figured out how …

Inspired by the prose of Dr. Peter Watts, I bring you Conan the Bacterium (otherwise known as deinococcus radiodurans, "..the toughest microbial motherfucker on the planet, a microbe who laughs at hard vacuum and radiation hot enough to cook you to a cinder.")
Picture from the Wikipedia article on deinococcus radiodurans. Quote from Conan the Barbarian. Picture of Peter Watts from here, originally taken by Allan Weiss. Macro engineered with the GIMP and cheezburger.com.
I'm on crack.

Geneticist Craig Venter of San Diego, California has made a significant breakthrough in genetics and bioengineering after it's been verified by the scientific community (I have to throw that disclaimer for reasons that'll be made clear in a moment)... he's built a chromosome out of raw materials in vitro.
Yeah. Not only did Venter's team, lead by Nobel Prize winner Dr. Hamilton O. Smith hooked synthetic nucleotides together one by one into a strand of DNA 580,000 base pairs in length, coding for 381 distinct genes, and then got the DNA to coil up into a chromosome. The synthetic …

A bioengineering firm called LS9 has done something remarkable with the bacteria e.coli (the Swiss Army Knife of gengineering) - they successfully engineered a strain to produce arbitrary hydrocarbon compounds in addition to the usual fatty acids that life on this planet uses to store energy. Specifically, the bacterial strains almost produce the hydrocarbons that are normally pumped out of the ground in the form of crude oil and then fractionated ("cracked") into different substances. Mix the right hydrocarbons together and you get gasoline. Or diesel fuel. Or the raw materials needed to make plastics.
I say 'almost' because the …
