krou writes "The BBC is reporting that a UK Royal Society report claims that geo-engineering proposals to combat the effects of climate change are 'technically possible.' Three of the plans considered showed the most promise: 'CO2 capture from ambient air'; enhancing 'natural reactions of CO2 from the air with rocks and minerals'; and 'Land use and afforestation'. They also noted that solar radiation management, while some climate models showed them to be ineffective, should not be ignored. Possible suggestions included: 'a giant mirror on the Moon; a space parasol made of superfine aluminum mesh; and a swarm of 10 trillion small mirrors launched into space one million at a time every minute for the next 30 years.'"

An anonymous reader writes "Biologists have discovered that a species of Australian pigeon has a secret way of alerting fellow birds to predators — a 'whistle' emitted by flapping wings when the bird takes off in alarm. The crested pigeon (Ocyphaps lophotes) is well known for the abrupt metallic-sounding whistle that it makes on takeoff. Many birds have the ability to make vocal cries to alert other members of their flock, but this is the first study to show that flight noise can also serve as an alarm call."

coondoggie writes "The airborne military laser which promises to destroy, damage or disable targets with little to no collateral damage has for the first time actually blown something up. Boeing and the US Air Force today said that on Aug. 30, a C-130H aircraft armed with Boeing's Advanced Tactical Laser (ATL) blasted a target test vehicle on the ground for the first time. Boeing has been developing the ATL since 2008 under an Air Force contract worth up to $30 million."

itwbennett writes "If you want to hire a hacker, you need to take a more psychology-based approach to the entire interview process to determine whether he or she has changed their ways enough to be a trustworthy employee, says Mich Kabay in a recent Network World blog post. But this approach is also 'germane for highly skilled staffers, even those that don't come with arrest records or who have done something questionable in their pasts,' says David Strom. For example, in your next interview, ask a question that will suss out how much of a sense of entitlement a candidate has — or how much you or your company has. 'One time when I interviewed with Microsoft in Redmond I couldn't get over this sense of corporate entitlement — it was one of the biggest turn-offs that I had during my interviewing day there,' says Strom. 'I got the feeling that I wasn't going to fit in, no matter how smart I thought (or they thought) I was.'"

NobodyExpects writes "I'd like to wish a happy birthday to the Internet! Today marks its 40th birthday! In fall 1969, computers sending data between two California universities set the stage for the Internet, which became a household word in the 1990s. On September 2nd 1969, in a lab at the University of California, Los Angeles, two computers passed test data through a 15-foot gray cable. Stanford Research Institute joined the fledgling ARPANET network a month later; UC Santa Barbara and the University of Utah joined by years end, and the internet was born."

The Narrative Fallacy writes "Cosmologist Lawrence M. Krauss, director of the Origins Initiative at Arizona State University, writes in the NY Times that with the investment needed to return to the moon likely to run in excess of $150 billion and the cost of a round trip to Mars easily two to four times that, there is a way to reduce the cost and technical requirements of a manned mission to Mars: send the astronauts on a one way trip. 'While the idea of sending astronauts aloft never to return is jarring upon first hearing, the rationale for one-way trips into space has both historical and practical roots,' writes Krauss. 'Colonists and pilgrims seldom set off for the New World with the expectation of a return trip.' There are more immediate and pragmatic reasons to consider one-way human space exploration missions including money. 'If the fuel for the return is carried on the ship, this greatly increases the mass of the ship, which in turn requires even more fuel.' But would anyone volunteer to go on such a trip? Krauss says that informal surveys show that many scientists would be willing to go on a one-way mission into space and that we might want to restrict the voyage to older astronauts, whose longevity is limited in any case.

KentuckyFC writes "Sodium acetate is the stuff inside chemical handwarmers that emits heat when it crystalizes after you press that little metal widget. That's why it is known as hot ice. Now a computer scientist in the UK has created a computer made entirely out of hot ice. The device processes information by exploiting the movement and interaction of wavefronts of crystallisation as they move through the material. The data input is in the form of metal wires that trigger crystal nucleation. The output works by reading off the direction of the moving wavefronts and the edges of the resulting crystals. The researcher has created AND and OR gates and solved a few problems such as finding the shortest path through mazes. There are even a few videos of the computer in action. The resulting computer is far from perfect, however. The data readout sometimes gives no solution and at other times gives circular results, the hot ice equivalent of a BSOD."

Xerolooper writes "What would the world be like if everyone could enjoy the same patent system we use in the USA? From the article: 'A senior lawyer at Microsoft is calling for the creation of a global patent system to make it easier and faster for corporations to enforce their intellectual property rights around the world.' They have already attracted opposition from the open-source community and the Pirate Party. According to the article, the World Intellectual Property Organization (WIPO) will be meeting in Geneva on the 17th and 18th of September."

Hugh Pickens writes "In 1935, JBS Haldane, one of the founders of modern genetics, studied a group of men with the blood disease hemophilia and speculated that there would be about 150 new mutations in each human being. Now BBC reports that scientists have used next generation sequencing technology to produce a far more direct and reliable estimate of the number of mutations by looking at thousands of genes belonging to two Chinese men who are distantly related, having shared a common ancestor who was born in 1805. To establish the rate of mutation, the team examined an area of the Y chromosome which is unique because, apart from rare mutations, the Y chromosome is passed unchanged from father to son so mutations accumulate slowly over the generations. Despite many generations of separation, researchers found only 12 differences among all the DNA letters examined. The two Y chromosomes were still identical at 10,149,073 of the 10,149,085 letters examined."

mikp writes "In a David-and-Goliath style fight, small music companies are battling it out with established behemoths to see who can own the future of mobile music. Spotify, the Europe-based music streaming company, is about to launch its iPhone app and has plans to develop it for other mobile platforms soon. In a preview, Spotify shows how you can cache songs to your iPhone so that you don't always need a connection but the songs don't remain on your iPhone permanently. Nokia, on the other hand, has just announced two more music phones that will feature Comes With Music, an unlimited music-download service that involves a one time fee, which is part of the price of the CWM phone, and lets you download music for free (and you get to keep it) for a year. The question remains, are people more likely to stream or download music on their mobile phones?"

Vladimir Sedach writes "Aside from authoring narrowly focused technical books, teaching university courses, or mentoring others in the workplace, programmers don't often get a chance to pass on the knowledge of the practise of programming as a profession. Peter Seibel's Coders at Work takes fifteen world-class programmers and distills their wisdom into a book of interviews with each of them." Keep reading for Vladimir's review.

denobug sends word that major internet service providers in the US are seeking to redefine the term 'Broadband' to mean a much lower speed than in other developed nations. In recent filings with the FCC, Comcast and AT&T both came out in support of a reduced minimum speed. 'AT&T said regulators should keep in mind that not all applications like voice over internet protocol (VoIP) or streaming video, that require faster speeds, are necessarily needed by unserved Americans.' On the other hand, Verizon argued to maintain the status quo, saying that 'It would be disruptive and introduce confusion if the commission were to now create a new and different definition.' A public interest group called Free Press also filed comments with the FCC, recommending that the bar should be set significantly higher, and evolve in a way that corresponds with technological improvements.

neuroworld writes to point out a study which found a correlation between in-game violence and a player's ability to recall advertisements seen while playing. The test subjects were given two versions of a driving game, which included "unobtrusive" billboard ads, and their eye movements were recorded by a camera. One version had players hitting targets for points, and the other version had them running down pedestrians. "[The researchers] found ads displayed along with violent scenes to be more memorable to players than those shown with nonviolent content, even though players spent less time looking at them. The results are contrary to expectations stemming from research on television, where violence has been shown to decrease attention to advertisements."
