Hawking: Alien contact "risky" for humans, death rays hard to duck

Hawking: avoid space aliens

Smartest guy in the known universe and all around inspiration, Stephen Hawking, has a message for everyone wanting to dial up aliens on the galactic party line: don't. On his new Discovery Channel series, Into the Universe with Stephen Hawking, the good professor warns that aliens might really be of the Hollywood variety. From ABC News:

"If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said. "We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet."

Read the rest and then find a table to hide under (not that it would help...)

Night vision glasses, cell phone cameras on the way!

Not-so-light-weight night vision...

Well, while scientists are still perfecting personal jet packs and flying cars, they've managed to whip up a few other goodies, namely, night vision in your prescription glasses using a film developed for flat screen TVs. MSNBC is on a roll with technology posts today:

Most night vision devices today use massive amounts of electricity — often several thousand volts, according to So — and heavy, glass lenses that maintain a vacuum to make the night come alive. So's device takes a radically different turn, replacing glass with thin plastic, eliminating the vacuum and using energy-efficient, organic LEDs.

Oh, let's just cut to the cool part already:

In other words, heavy and bulky night vision goggles could be replaced with a thin, lightweight coating weighing less than half a deck of playing cards.

According to the article it should take about a year-and-a-half to apply the new tech to car windshields, lightweight night vision eyeglasses and mobile devices.

Space "Taxis" Make for Cheaper, Less Complicated Flights

The future of spaceflight is streamlined, cheap flights with no need for bells and whistles--like say, airlocks. MSNBC analyst James Oberg has a great piece on how private space corporations are aiming for inexpensive vehicles that get astronauts from point a to point b without having to spend a lot of time in orbit or performing other tasks. Since the main mission would be immediately dock with a space station or ship already in orbit, NASA and other agencies are looking at vehicles akin to the Soyuz class capsules or something similar to the Gemini/Mercury programs that the US sent up in the 60s. Oberg puts up a few design suggestions of his own:

• Electrical power? Batteries are fine — recharge when you reach the station, or if you can’t, land immediately. No solar panels, no fuel cells, nothing complex or exotic.
• Navigation? Big radar dishes, even complex transponders, are unnecessary, with differential GPS navigation now the baseline for most flying all over the planet.
• Spacewalking? No need, so no airlock, either. At most, the crew would wear in-cabin pressure suits such as those used on Soyuz missions.
• Passenger accommodations? Room for each passenger in a foldaway seat, and space to turn around if desired would be more than adequate for the short flight. No exercise equipment would be needed. No DVD library.
• Hygiene? A maximum of 24 hours of independent flight suggests a minimum toilet (or just Apollo-era plastic bags with sticky openings). Or low-residue pre-launch diets, and diapers.
• Passenger comforts? None. Forget hot food and a complex galley. Box lunches will do. Forget even windows, except for the pilot’s view forward at docking. There need only be minimal carry-on luggage — a take-aboard allowance that would make today’s commercial airlines seem generous.
• Bulky docking hardware? These mechanically robust components are often a significant fraction of a spaceship’s weight, but the space station can also now grapple a nearby vehicle and emplace it gently on the desired berthing interface.

4,000-Year-Old Euro Mummies Found in... China?!

A cemetery of 200 mummy's from four millennia ago has been discovered in the Xinjiang of China (north of Tibet)--extremely well preserved thanks to the arid air of the Gobi Desert. The rest of the story is so weird that the NYT does better than I ever could at recounting. From the New York Times:

Their remains, though lying in one of the world’s largest deserts, are buried in upside-down boats. And where tombstones might stand, declaring pious hope for some god’s mercy in the afterlife, their cemetery sports instead a vigorous forest of phallic symbols, signaling an intense interest in the pleasures or utility of procreation.

Of course! How else can you find a cemetery of mummies under a pile of boats? There's more...

The 200 or so mummies have a distinctively Western appearance, and the Uighurs, even though they did not arrive in the region until the 10th century, have cited them to claim that the autonomous region was always theirs. Some of the mummies, including a well-preserved woman known as the Beauty of Loulan, were analyzed by Li Jin, a well-known geneticist at Fudan University, who said in 2007 that their DNA contained markers indicating an East Asian and even South Asian origin.

The mummies in the Small River Cemetery are, so far, the oldest discovered in the Tarim Basin. Carbon tests done at Beijing University show that the oldest part dates to 3,980 years ago. A team of Chinese geneticists has analyzed the mummies’ DNA.
