Surface heat data from the Venus Express spacecraft show the most likely sites of volcanic activity on Venus. Researchers using data from the European Space Agency’s Venus Express spacecraft said they spotted three active volcanoes that recently poured red hot lava onto the planet’s already broiling surface. The discovery, announced in a paper published Friday online in Science, suggests that Venus — like the Earth — is periodically resurfaced by lava flows, explaining why it seems devoid of craters.
British scientific expedition discovers world's deepest known undersea volcanic vents
A British scientific expedition has discovered the world's deepest undersea volcanic vents, known as 'black smokers', 3.1 miles (5000 metres) deep in the Cayman Trough in the Caribbean. Using a deep-diving vehicle remotely controlled from the Royal Research Ship James Cook, the scientists found slender spires made of copper and iron ores on the seafloor, erupting water hot enough to melt lead, nearly half a mile deeper than anyone has seen before. Deep-sea vents are undersea springs where superheated water erupts from the ocean floor. They were first seen in the Pacific three decades ago, but most are found between one and two miles deep. Scientists are fascinated by deep-sea vents because the scalding water that gushes from them nourishes lush colonies of deep-sea creatures, which has forced scientists to rewrite the rules of biology. Studying the life-forms that thrive in such unlikely havens is providing insights into patterns of marine life around the world, the possibility of life on other planets, and even how life on Earth began.

Scientists on Wednesday, April 7, 2010 said that Glacier National Park has lost two more of its namesake moving icefields to climate change, which is shrinking the rivers of ice until they grind to a halt.

They once numbered as many as 150, and 37 of those glaciers eventually were named.
After first providing us with driving directions and then taking on turn-by-turn for public transportation and pedestrian travel, Google has tackled the bike commute. The beta version of Google’s bike-friendly directions offers some great routes for two-wheeled transportation as long as riders have brains under their helmets. Wired asked cyclists from all over the United States to try Google Bikes‘ suggestions for their daily rides. More than twenty of you got back to us with very detailed reviews. Some of you even sent in screenshots of the maps themselves, which earns you a collective A+ for effort. We hope you offered similar advice to Google on their “Report a Problem” link — that’s the only way to make the beta better.
By now, you are drowning in commentary on the iPad. So, let me get to the point: Don't be fooled by the fancy hardware and "magical" talk: Apple isn't really committed to tablet computing...yet. This can be hard to appreciate when you hold a truly gorgeous object in your hand. Hardware seems much more convincing than a piece of software or website could ever be. But, unfortunately, hardware is easy*. That is why Nokia, and the like, can churn out hundreds of handset models a year for different markets. Software, on the other hand, is very very hard.
