Hope nobody gave a patent to him, since we've had a doorbell like this in my house for some time now.

You ring my apartment from the entrance and my mobile rings and I can talk to whoever is outside, and I can also unlock the door for them remotely from my phone. Much appreciated by friends who show up early and otherwise would have had to wait outside until I got back home.

I got myself a place 5 minutes by Segway from work, and then bought a Segway.

Hell, you'd have to pay me extra to telecommute!

The Proton Just Got Smaller 289

inflame writes "A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."' Would this indicate new physics if proven?"

What Scientists Really Think About Religion 1123

Hugh Pickens writes "The Washington Post has a book review of Science and Religion: What Scientists Really Think by Rice University sociologist Elaine Ecklund, who spent four years doing a detailed survey of 1,646 scientists at elite American research universities. The study reveals that scientists often practice a closeted faith, worrying about how their peers would react to learning about their religious views. 'After four years of research, at least one thing became clear: Much of what we believe about the faith lives of elite scientists is wrong. The '"insurmountable hostility" between science and religion is a caricature, a thought-cliche, perhaps useful as a satire on groupthink, but hardly representative of reality,' writes Ecklund. Unsurprisingly, Ecklund found that 64% of scientists are either atheists (34%) or agnostic (30%). But only five of the 275 in-depth interviewees actively oppose religion; and even among the third who are atheists, many consider themselves 'spiritual.' 'According to the scientists I interviewed, the academy seems to have a "strong culture" that suppresses discussion about religion in many areas,' says Ecklund. 'To remove the perceived stigma, we would need to have more scientists talking openly about issues of religion, where such issues are particularly relevant to their discipline.'"

The Sun's Odd Behavior 285

gyrogeerloose writes "Most of us know about the sun's eleven-year activity cycle. However, relatively few other than scientists (and amateur radio operators) are aware that the current solar minimum has lasted much longer than expected. The last solar cycle, Cycle 24, bottomed out in 2008, and Cycle 25 should be well on its way towards maximum by now, but the sun has remained unusually quiescent with very few sunspots. While solar physicists agree that this is odd, the explanation remains elusive."

A Genetically Engineered Fly That Can Smell Light 111

An anonymous reader writes "It sounds like a cool — if somewhat pointless — super-powered insect: a fly that can smell light! Researchers added a light-sensitive protein to a fruit fly's olfactory neurons, which caused the neurons to fire when the fly was exposed to a certain wavelength of blue light. Adding the protein specifically to neurons that respond to good smells, like bananas, makes for a light-seeking fly."

IBM Distributes USB Malware At Security Conference 73

bennyboy64 and other readers let us know that IBM sent out an email to all attendees to the Australian Computer Emergency Response Team (AusCERT) 2010 conference, warning them that some of the USB drives handed out to delegates contained malware. Fortunately it was old malware, which all anti-virus products have detected since 2008. Two years ago telecommunications company Telstra distributed malware-infected USB drives at the same conference.

Why Overheard Cell Phone Chats Are Annoying 344

__roo writes "American researchers think they have found the answer to the question of why overhearing cell phone chats are annoying. According to scientists at Cornell University, when only half of the conversation is overheard, it drains more attention and concentration than when overhearing two people talking. According to one researcher, 'We have less control to move away our attention from half a conversation (or halfalogue) than when listening to a dialogue. Since halfalogues really are more distracting and you can't tune them out, this could explain why people are irritated.' Their study will be published in the journal Psychological Science."

10,000 Cows Can Power 1,000 Servers 221

from the cattle-computing dept.

CWmike writes "Reducing energy consumption in data centers, particularly with the prospect of a federal carbon tax, is pushing vendors to explore an ever-growing range of ideas. HP engineers say that biogas may offer a fresh alternative energy approach for IT managers. Researchers at HP Labs presented a paper (download PDF) on using cow manure from dairy farms and cattle feedlots and other 'digested farm waste' to generate electricity to an American Society of Mechanical Engineers conference, held this week. In it, the research team calculates that 'a hypothetical farm of 10,000 dairy cows' could power a 1 MW data center — or on the order of 1,000 servers. One trend that makes the idea of turning organic waste into usable power for data centers is the moves by several firms to build facilities in rural locations, where high-speed networks allow them to take advantage of the cost advantages of such areas. But there are some practical problems, not the least of which is connecting a data center to the cows. If it does happen, the move could call for a new take on plug and play: plug and poo."

New Estimates Say Earth's Oceans Smaller Than Once Believed 263

Velcroman1 writes with this snippet from Fox News: "Using lead weights and depth sounders, scientists have made surprisingly accurate estimates of the ocean's depths in the past. Now, with satellites and radar, researchers have pinned down a more accurate answer to that age-old query: How deep is the ocean? And how big? As long ago as 1888, John Murray dangled lead weights from a rope off a ship to calculate the ocean's volume — the product of area and mean ocean depth. Using satellite data, researchers from the Woods Hole Oceanographic Institute set out to more accurately answer that question — and found out that it's 320 million cubic miles. And despite miles-deep abysses like the Mariana Trench, the ocean's mean depth is just 2.29 miles, thanks to the varied and bumpy ocean floor."
