the retail dna test
learning and sharing your genetic secrets are at the heart of 23andme's controversial new service — a $399 saliva test that estimates your predisposition for more than 90 traits and conditions ranging from baldness to blindness. although 23andme isn't the only company selling dna tests to the public, it does the best job of making them accessible and affordable. the 600,000 genetic markers that 23andme identifies and interprets for each customer are "the digital manifestation of you," says wojcicki (pronounced wo-jis-key), 35, who majored in biology and was previously a health-care investor. "it's all this information beyond what you can see in the mirror."

the tesla roadster
electric cars were always environmentally friendly, quiet, clean — but definitely not sexy. the tesla roadster has changed all that. a battery-powered sports car that sells for $100,000 and has a top speed of 125 m.p.h. (200 km/h), the roadster has excited the clean-tech crowd since it was announced in 2003. celebrities like george clooney joined a long waiting list for the roadster- magazines like wired drooled over it. after years of setbacks and shake-ups, the first tesla roadsters were delivered to customers this year. reviews have been ecstatic, but tesla motors has been hit hard by the financial crisis. plans to develop an affordable electric sedan have been put on hold, and tesla is laying off employees. but even if the roadster turns out to be a one-hit wonder, it's been a hell of

the lunar reconnaissance orbiter
it may have been a long time since the u.s. built the world's best cars, but nobody can touch us when it comes to spacecraft. nasa is about to prove that again with the planned launch in february 2009 of the lunar reconnaissance orbiter (lro). our first unmanned moonship in 11 years, the lro will study the things lunar orbiters always study — gravity, temperature — but it will also look for signs of water ice, a vital resource for any future lunar base, and compile detailed 3-d lunar maps, including all six apollo landing sites. wingnuts, be warned: yes, we really went there.

hulu.com
when cable eventually dies, websites like hulu will be held responsible. unlike youtube and other amateur-video-upload sites, hulu is a hub for network tv shows and movies: hulu offers shows from nbc, fox, pbs and other channels, including free full episodes of snl, the daily show, the office and other hits the tivo-less masses often miss, plus films like ghostbusters, the fifth element and lost in translation. created as a network-approved alternative to youtube's grab bag, hulu was at first roundly mocked as a ham-fisted corporate knockoff of the grass-roots glory that is youtube. (it was also mocked for its weird name.) instead it proved that suits can play in the internet video space too and that studio content can coexist online with the user-generated kind. in doing so, it delivered

the large hadron collider
if someone invented a practical 200-m.p.g. automobile and that automobile got a flat tire, nobody would claim that the car itself was a failure. the same applies to the large hadron collider, the world's biggest particle accelerator, which went online in september, ran for 10 days and then had to shut down at least until next spring because of an overheated wire. the mammoth machine will send protons wheeling in opposite directions at nearly the speed of light, then smash them together at 6,000 times a second to try to answer such deep questions as why mass exists and whether the universe has extra dimensions. if it takes a few extra months to find out, so what?

the global seed vault
superman had it right: if you want to keep something safe, build a mountain fortress above the arctic circle. that's the thinking — more or less — behind the svalbard global seed vault. almost every nation keeps collections of native seeds so local crops can be replanted in case of an agricultural disaster. the global seed vault, opened this year on the far-northern norwegian island of spitsbergen, is a backup for the backups. it's badly needed — as many as half the seed banks in developing countries are at risk from natural disasters or general instability. the vault can hold up to 4.5 million samples, which will be kept dry at about 0°f (-18°c). even if the facility loses power, the arctic climate should keep the seeds viable for thousands of years. let's just hope we still

the chevy volt
no-emission electric motors — which began the automobile revolution — are the technology of tomorrow for cars. but today's batteries can't support the typical driving experience. chevy's volt is a nice compromise. the sedan has an electric motor with a battery that can provide up to 40 miles (about 65 km) of range on a single charge. a gas engine kicks in to recharge the battery while you're driving. since nearly 80% of us drive less than 40 miles a day, that means that unlike the prius, the volt could get drivers off gas altogether. the best of both worlds lands by the end of 2010.

bullets that shoot bullets
think of the army's new active protection system (aps) as star wars for soldiers, designed to protect them from rocket-propelled grenades and other short-range threats. raytheon's aps will automatically detect an incoming round and then launch a missile to destroy it, all within a split second. if it works, future army vehicles will be able to head into combat with less armor.

the orbital internet
in space, no one can hear you scream. but you will be able to send e-mail, thanks to a new protocol being developed for use there. it's hard to maintain a stable connection in orbit, so the interplanetary internet will have to be especially tolerant of delays and disruptions. in september, a satellite used the new protocol to relay an image of the cape of good hope back to earth.

the world's fastest computer
on may 26, at 3:30 in the morning, a $133 million supercomputer nicknamed roadrunner broke the long-sought-after petaflop barrier: 1 quadrillion calculations per second. built by ibm for los alamos national laboratory, roadrunner will be used primarily to simulate the effects of aging on nuclear weapons. next up: the exaflop barrier.
