kasparn writes "The Guardian today has a story about the Danish astrophysicist Rasmus Bjoerk, who recently conducted simulations on how long it will take to colonize the Milky Way. The basic idea is to send out probes in different directions (including various heights above the galactic plane). He estimates that it will take some 10 billion years to explore 4 % of the Milky Way. Since the age of the Universe is of the same order, his conclusion is that aliens can't have had time required to find us yet."

An anonymous reader points out an article in IBM's Crossing Borders series about the language features of JavaScript, surely the Rodney Dangerfield of scripting languages. But with increasing use in such technologies as Ajax, Apache Cocoon, ActionScript, and Rhino, some industry leaders are taking a fresh look at the language. From the article: "Nearly every Web developer has cursed JavaScript at one time or another. Until recently, many developers had all but written off JavaScript as a necessary evil at best or a toy at worst... But JavaScript is becoming increasingly important, and it remains the most broadly available scripting language for Web development."

anaesthetica writes "Physorg.com is featuring a story asserting that hydrogen is economically infeasible as a replacement for our current energy sources. The premise is that isolating and converting hydrogen into a usable energy source takes up a great deal of energy to begin with, and that subsequently converting that hydrogen fuel into usable energy results in an overall efficiency of only about 25%. Apparently, the increasing scarcity of water is going to make hydrogen too costly and just as politicized as oil." From the article: "[Fuel cell expert Ulf Bossel's] overall energy analysis of a hydrogen economy demonstrates that high energy losses inevitably resulting from the laws of physics mean that a hydrogen economy will never make sense. The advantages of hydrogen praised by journalists (non-toxic, burns to water, abundance of hydrogen in the Universe, etc.) are misleading, because the production of hydrogen depends on the availability of energy and water, both of which are increasingly rare and may become political issues, as much as oil and natural gas are today."

gt_mattex writes to tell us The Globe and Mail is reporting that quite a few new species have been found in the ocean beneath the Antarctic ice. From the article: "It is too early to say exactly how many new species were discovered in the Antarctic, many in the Weddell Sea, where ice crushed the ship of Antarctic explorer Ernest Shackleton in 1915. The scientists saw more strange creatures than familiar ones, says Ron O'Dor, an expert in octopuses and squid from Halifax's Dalhousie University and the chief scientist in charge of producing the first marine life census of the planet by 2010."

An anonymous reader writes, "According to a CNet article, two companies called Mobience and Nuance have created viable and possibly better alternatives to the standard cell phone keypad. 'Mobience, which is based in South Korea, has redesigned the ABC and Qwerty key layout, and come up with MobileQwerty. It's essentially the same three-letters-per-key system as the standard mobile keypad layout, but the letters have been rearranged in a Qwertyesque way to increase efficiency.' The other system developed by Nuance is a mobile speech platform that turns speech into text and replaces the keypad altogether. I was skeptical at first but the video of Nuance's software vs. Ben Cook, the ex world texting champion, is undeniably impressive."
