Comment Re:Replicator (Score 5, Insightful) 633

Actually we have more than enough food to go around right now. We don't have a food shortage problem we have a wealth inequality problem. This is a political/moral problem. A replicator would not change this any more then refrigeration, fertilizer, or tractors solved the hunger problem (despite the huge increases in food production they enabled).

Comment Carefully Targeted (Score 1) 361

The researchers who found this noticed it will only activate on certain controllers that are controlling centerfuges built in either Iran or Poland I believe. There are additional restrictions, I think something about a certain percentage must be or Iranian manufacture of something. Since there are virtually no Iranian centrifuges outside of Iran it is as targeted as it is possible to be to only Iranian nuclear processing facilities.

Scientists really have to do a better job at communicating clearly with less jargon

While I tend to agree with you about jargon, the ironic thing is that jargon is explicitly created to communicate more clearly. It is all about speaking to your audience, if you are talking to a fellow slashdotter you say "dual core CPU", if you are talking to your grandparents you say "computer with two brains". Both are very clear to their target audience and incomprehensible drivel to the other, so which is "communicating clearly"? Many concepts are very hard to break down into terms of microwave ovens, buying groceries, and fixing your car analogies. But I agree that just because something is hard that we should quit trying.

Comment Phone Manufacturers Don't Upgrade Software (Score 3, Interesting) 636

The real issue here isn't an Android problem at all, it is the fact that manufacturers/carriers never upgrade the software. They have no incentive to, they already sold the product and made their money, why would they waste time/money making sure the new version will work? It actually works in their favor not to as the customers have to spend more money getting a new phone with new software. Until you actually own your phone and can upgrade it at your discretion this will continue to be a problem. Or buy something from Apple who actually understands this and has the clout to force it on the carriers.

Breaking the Squid Barrier 126

An anonymous reader writes "Dr. Steve O'Shea of Auckland, New Zealand is attempting to break the record for keeping deep sea squid alive in captivity, with the goal of being able to raise a giant squid one day. Right now, he's raising the broad squid, sepioteuthis australis, from egg masses found in seaweed. This is a lot harder than it sounds, because the squid he's studying grow rapidly and eat only live prey, making it hard for them to keep the squid from becoming prey themselves. If his research works out, you might one day be able to visit an aquarium and see giant squid."

Directed Energy Weapon Downs Mosquitos 428

wisebabo writes "Nathan Myhrvol demonstrated at TED a laser, built from parts scrounged from eBay, capable of shooting down not one but 50 to 100 mosquitos a second. The system is 'so precise that it can specify the species, and even the gender, of the mosquito being targeted.' Currently, for the sake of efficiency, it leaves the males alone because only females are bloodsuckers. Best of all the system could cost as little as $50. Maybe that's too expensive for use in preventing malaria in Africa but I'd buy one in a second!" We ran a story about this last year. It looks like the company has added a bit more polish, and burning mosquito footage to their marketing.

If 99% of the people are idiots and 1% of them ask a question you cannot immediately answer; congratulations: you just got 1% smarter and 1% is a HUGE gain in any endeavour worth earnestly chasing.

That sounds very good until you have to deal with that 99% who are trying to discredit you and ruin your career. You should read to get a little taste for the kind of "questions" you usually get: http://www.conservapedia.com/Conservapedia:Lenski_dialog The whole question is a little bit mute anyway as a mechanism for dealing with this, any many other problems, is already used: replication of results. Published results are generally not widely accepted until they can be replicated in a different lab. This overcomes any coding errors, but more importantly, equipment errors, user errors, random chance, and even active data manipulation. I think what most people who are not actively involved in research fail to realize is what an iterative process science is. Early results are often, maybe even usually, error ridden. This can come from bad code or anything else. But as more people work on it and improve it the errors are removed and the final product is something very close to ground truth, and the longer it is discussed the closer it gets to that goal. If you don't believe me I would ask you where you think computers, automobiles, pain killers, vaccines, rockets, cameras, genetically modified mice, and skyscrapers come from. All of those required an incredible detailed, and accurate, knowledge of how the working components function. Science, it works bitches.

Signs of Water Found On Saturnian Moon Enceladus 79

Matt_dk writes "Scientists working on the Cassini space mission have found negatively charged water ions in the ice plume of Enceladus. Their findings, based on analysis from data taken in plume fly-throughs in 2008 and reported in the journal Icarus, provide evidence for the presence of liquid water, which suggests the ingredients for life inside the icy moon. The Cassini plasma spectrometer, used to gather this data, also found other species of negatively charged ions including hydrocarbons."

A Hyper-Velocity Impact In the Asteroid Belt? 114

astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."

Photovoltaic Eye Implant Could Give Sight To the Blind 15

MikeChino writes with this snippet from Inhabitat: "Researchers at Stanford University recently announced that they have developed a new artificial retina implant that uses photovoltaic power and could help the blind see. The problem with previous implants was that there was no way send power to the chip in order to process light and data inside the eye, so the new device uses miniature photovoltaic cells to provide power the chip as well as to transmit data through the eye to the brain. The new device has great promise to help people afflicted by the loss of photoreceptor cells by using the power of the sun."

This functionality and resolution is easy to get and can be obtained from a normal single photo, not 1655. All you need is a standard "enhancement" filter found on any movie of TV show worth its salt. You zoom in, everything is blurry, enhance, it gets clear again and repeat ad nauseum, or at least until the scientists in your audience are nauseated.

Yellowstone Supervolcano Larger Than First Thought 451

drewtheman writes "New studies of the plumbing that feeds the Yellowstone supervolcano in Wyoming's Yellowstone National Park shows the plume and the magma chamber under the volcano are larger than first thought and contradicts claims that only shallow hot rock exists. University of Utah research professor of geophysics Robert Smith led four separate studies that verify a plume of hot and molten rock at least 410 miles deep that rises at an angle from the northwest."

Big Dipper "Star" Actually a Sextuplet System 88

Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."
