Bionic fingers and surgically-switched fingerprints. Dark matter in Minnesota, and "VSS Enterprise" space-tourist test flights. The future, my friends, is here on PopSci.com.
(Get the details, and win the t-shirt, after the jump).
Apparently men and women are not that different after all. In fact, the sexes are so similar that women have to fight their entire lives just to remain women -- at least on the genetic level.
A new study finds that turning off just one gene, shared by all mammals, turns ovarian cells into testosterone-producing cells found only in the testes -- and this is in adults.
A lot of the climate change debate may focus on how to cut carbon dioxide emissions to prevent global temperature rise, but many nations are already struggling with the consequences of local climate change--rising sea levels, water shortages and agricultural problems. Now the European Union has promised over $10 billion over the next three years for a "fast start" fund to help the poorest nations adapt to climate change.

About 20 percent of watermelons are left to rot in the field because they’re too blemished to sell in stores. Scientists from the USDA’s Agricultural Research Service found that the unused fruit left on a harvested acre could produce about 24 gallons of bioethanol—fuel that could be poured back into farm equipment or sold on the open market, all without competing for land with food crops. This year, the group plans to start work on a mobile machine that could go from field to field harvesting castaway melons and turning them into fuel.
Saturn's north pole holds something even more strange than a globe-trotting Santa Claus -- a giant hexagon shape within the planet's atmosphere. Now NASA's Cassini spacecraft has imaged the whole hexagonal pattern in visible light for the first time.
It seems like every few weeks someone claims to have built the newest and most revolutionary prosthetic hand, and while breakthroughs on that front are amazing, what about all the partial-hand amputees, those that have only lost a finger or two, or perhaps a thumb? UK firm Touch Bionics has introduced a system geared directly toward those that, though missing a digit or four, still have working muscle and tendon in their hands. These bionic fingers let their wearers--a 1.2-million-strong group that, until now, has been largely ignored--regain the ability to type, use a fork and knife and more.
A bizarre spiraling light show over Norway has raised speculations ranging from a Russian rocket test to an odd meteoric display. The Norwegian Meteorological Institute remains unsure of the phenomenon's origins, but astronomers have said that it does not appear connected to the Aurora Borealis, also known as the Northern Lights.
