Price Shocks May Be Coming For Helium Supply 362

Posted by kdawson on Monday July 05, 2010 @07:19PM from the squeaky-voice-price-inflation dept.

Ars has an update on the potential helium shortage we discussed a couple of years back. A Nobel laureate, Robert Richardson, argues for ending market distortions that are resulting in an artificially low price for helium, which is accelerating the projected exhaustion of the supply. "Richardson's solution is to rework the management of the Bush Dome [so named for reasons that have nothing to do with the politician] stockpile once again, this time with the aim of ensuring that helium's price rises to reflect its scarcity. In practical terms, he said that it would be better to deal with a 20-fold increase in price now than to deal with it increasing by a factor of thousands in a few decades when supply issues start to become critical. But he also made an emotional appeal, stating, 'One generation doesn't have the right to determine the availability forever.'"

Fermilab Experiment Hints At Multiple Higgs Particles 271

krou writes "Recent results from the Dzero experiment at the Tevatron particle accelerator suggest that those looking for a single Higgs boson particle should be looking for five particles, and the data gathered may point to new laws beyond the Standard Model. 'The DZero results showed much more significant "asymmetry" of matter and anti-matter — beyond what could be explained by the Standard Model. Bogdan Dobrescu, Adam Martin and Patrick J Fox from Fermilab say this large asymmetry effect can be accounted for by the existence of multiple Higgs bosons. They say the data point to five Higgs bosons with similar masses but different electric charges. Three would have a neutral charge and one each would have a negative and positive electric charge. This is known as the two-Higgs doublet model.'" There's more detail in this writeup from Symmetry Magazine, a joint publication of SLAC and Fermilab. Here's the paper on the arXiv.

The Real Science Gap 618

walterbyrd writes "This article attempts to explain why the US is struggling in its competition with other countries in the realm of scientific advancement. 'It's not insufficient schooling or a shortage of scientists. It's a lack of job opportunities. Americans need the reasonable hope that spending their youth preparing to do science will provide a satisfactory career.' I can hardly believe that somebody actually understands the present situation. It continues, 'The current approach — trying to improve the students or schools — will not produce the desired result, the experts predict, because the forces driving bright young Americans away from technical careers arise elsewhere, in the very structure of the US research establishment. For generations, that establishment served as the world’s nimblest and most productive source of great science and outstanding young scientists. Because of long-ignored internal contradictions, however, the American research enterprise has become so severely dysfunctional that it actively prevents the great majority of the young Americans aspiring to do research from realizing their dreams.'"

Set Free Your Inner Jedi (Or Pyro) 463

sirgoran writes "We've all thought about being the hero fighting off evil-doers and saving the day ever since we first saw Star Wars. The folks at Wicked Lasers have now brought that a little closer to reality with their latest release: a 1-Watt blue diode laser that can set skin and other things on fire. From an article at Daily Tech, where they talk about the dangers of such a powerful laser: 'And here's the best (or worst) part — it can set people (or things) on fire. Apparently the laser is so high-powered that shining it on fleshy parts will cause them to burst into flames. Of course it's equally capable of blinding people.' The thing that caught my eye was the price: $200. I wonder if they'll be able to meet the demand, since (if it works as advertised) this will be on every geek's Christmas list."

Olympus Digital Camera Ships With a Worm 249

Posted by kdawson on Tuesday June 08, 2010 @09:11PM from the do-not-get-too-close-to-the-viewfinder dept.

An anonymous reader writes "Olympus Japan has issued a warning to customers who have bought its Stylus Tough 6010 digital compact camera that it comes with an unexpected extra — a virus on its internal memory card. The Autorun worm cannot infect the camera itself, but if it is plugged into a Windows computer's USB port, it can copy itself onto the PC, then subsequently infect any attached USB device. Olympus says it 'humbly apologizes' for the incident, which is believed to have affected some 1,700 units. The company said it will make every effort to improve its quality control procedures in future. Security company Sophos says that more companies need to wake up to the need for better quality control to ensure that they don't ship virus-infected gadgets. At the same time, consumers should learn to always ensure Autorun is disabled, and scan any device for malware before they use it on their computer."

Methane-Eating Bacteria May Presage ET Life 91

Posted by kdawson on Tuesday June 08, 2010 @07:20PM from the to-each-its-own dept.

asukasoryu sends along an intriguing piece in light of our recent discussion of possible signs of life on Saturn's moon Titan. "Researchers have discovered that methane-eating bacteria survive in a unique spring located on Axel Heiberg Island in Canada's extreme north. The subzero water is so salty that it doesn't freeze despite the cold, and it has no consumable oxygen in it. There are, however, big bubbles of methane that come to the surface. Lyle Whyte, McGill University microbiologist, explains that the so-called Lost Hammer spring supports microbial life, that the spring is similar to possible past or present springs on Mars, and that therefore they too could support life."

2 In 3 Misunderstand Gas Mileage; Here's Why 1042

Posted by kdawson on Tuesday June 08, 2010 @06:34PM from the bad-at-math dept.

thecarchik sends in this piece, which was published last March but remains timely: "OK, so here's a little test: Which saves more gasoline, going from 10 to 20 mpg, or going from 33 to 50 mpg? If you're like most Americans, you picked the second one. But, in fact, that's exactly backwards. Over any given mileage, replacing a 10-mpg vehicle with one that gets 20 mpg saves five times the gasoline that replacing a 33-mpg vehicle with one that gets 50 does. Last summer, Duke University's Fuqua School of Business released a study that shows how much damage comes from using MPG instead of consumption to measure how green a car is. Management professors Richard Larick and Jack Soll's experiments proved that consumers thought fuel consumption was cut at an even rate as mileage increased."
