As the Northeast and South brace for yet another day of record snow fall, thousands of Americans are struggling with ways to deal with treacherous road conditions. Thankfully, some intrepid Russian DIYers have a plan: convert your car to use tank treads.
Give the National Weather Service some credit for some clever crowdsourcing experiments. It has just launched a Twitter-based program to monitor tweets about severe weather, and hopes to eventually transform cars into mobile weather stations, Discovery News reports.
What do tiny smiling snowmen mean for science? Not much; these physicists just decided to show off their ability to make really small things.
This little guy measures just 10 micrometers across, or just 1/5th the width of a human hair. Scientists at the National Physics Laboratory in the UK built the snowman body from two tin beads, and milled the eyes and smile in the top bead using a focused ion beam. The snowman also has a platinum nose deposited by said ion beam, which probably beats a silly carrot any day.
Yamaha's air-shock snowmobile lets adventurers explore more territory

The 2010 snowmobile season, which begins this month, will see daredevils in places they couldn't reach before: in deeper powder, on remote cliffs, squeezing between trees. That's because the first full air-suspension sled swaps the usual heavy steel coils for air-filled shock absorbers, creating a smoother, 20-pounds-lighter machine. Riders can easily steer the FX Nytro MTX SE 162 with their weight, glide it nearly drag-free through powder, and unstick it from drifts.
While it lacks the subtle charm of Alberto Tomba, this robot is just as much at ease flying down a slalom course. Designed by Bojan Nemec of the the Jozef Stefan Institute in Slovenia, the robot utilizes two computers to stay upright and pointed downhill.
Controlling the weather with cloud seeding has previously proved popular with Chinese and Russian officials, but Moscow's mayor does not seem content with just keeping the rain off his roofs. Now Mayor Yury Luzhkov has hired the cash-strapped Russian Air Force to chemically spray clouds so that no snow will fall within his city limits.
Even with a vehicle that has 4WD and high clearance, there are a few times each winter when I can't make it up my 1,000-foot-long driveway without a little extra help. Usually that means untangling a set of ice-cold chains and then trying to secure them to my wheels before my fingers go numb...all while holding a flashlight between my teeth. Chaining up is never as quick or as easy as the instructions would suggest.
When Kai Grundt announced his decision to build the ultimate snowblower from a discarded V8 engine, a friend of his just laughed. So a year later, instead of showing his buddy the finished product, Grundt showed him what it could do. He buried the man's truck under a seven-foot-tall pyramid of snow. From two houses away.
In a Mars exploration milestone, a laser remote sensing instrument on the Phoenix Mars lander has detected snow falling on the red planet. Data from the light detection and ranging (lidar) instrument—designed to gather information about interactions between the Martian atmosphere and ground surface—showed the snow falling from clouds about 4 kilometers (2.5 miles) above the spacecraft's landing site.
