Submission + - US experiment hints at 'multiple God particles' (bbc.co.uk) 1

Submitted by krou
krou writes: Recent results from the Dzero experiment at the Tevatron particle accelerator suggest that those looking for a single Higgs boson particle should, in fact, 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.'

ITER Fusion Reactor Enters Existential Crisis 470

Posted by timothy from the sartre-says-it's-meaningless dept.
deglr6328 writes "The long beleaguered experimental magnetic confinement fusion reactor ITER is currently in what some are calling the worst crisis of its 25 year history. Still existing only on the paper of thousands of proposed design documents, the latest cost estimates for the superconducting behemoth are soaring to nearly 20 billion USD — roughly twice the estimates from as recently as a few years ago. Anti-nuclear environmentalist organizations have seized upon the moment as an opportunity to use the current global economic crisis as a means to push for permanently killing the project. If ITER is not built, the prospect of magnetic confinement fusion as a technique to reach thermonuclear breakeven and ignition in the laboratory would be in serious question. Meanwhile, the largest laser-driven inertial confinement fusion project, the National Ignition Facility, has demonstrated the ability to use self-generated plasma optical gratings to control capsule implosion symmetry with high finesse, and is on schedule to achieve ignition and potentially high gain before the end of the year."

In the spirit of NASA and its forthcoming 2020 lunar expeditions in preparation for colonizing the moon

Shouldn't it be disguised as a moon rock then? And what's the purpose of hiding a rover on a colonized moon? Is this some sort of lunar Big Brother project? GoogleVan, is that you?

Submission + - Can transistors be made to work when they are off? (eetimes.com)

Submitted by Anonymous Coward
An anonymous reader writes: Engineers at the Belgian research institute IMEC are looking at the use of silicon transistors in the sub-threshold region of their operation as a way of pursuing ultra-low power goals. A chip the engineers are designing for biomedical applications could have blocks designed to operate at 0.2 or 0.3 volts, researchers said, according to EE Times.

The threshold voltage is the point at which the transistor nominally switches off. Operating a transistor when it is "off" would make use of the leakage conduction that is normally seen as wasted energy, according to the article.

Submission + - Biodegradable Sugar-Powered Batteries, Coming Soon (physorg.com)

Submitted by srsguy
srsguy writes: In the past, we've seen cell phones powered by cola. Now, researchers at Saint Louis University in Missouri are attempting to commercialize batteries powered purely by sugar — not from just one source, either. The team is making claims that "[d]evices could be instantly recharged by adding virtually any convenient sugar source, including plant sap". This should keep the world's sugar-fueled youth with plenty of power — up to 4 times longer on a single charge, in fact.

Feed Ars Technica: LEDs may put lasers out of quantum computing business (arstechnica.com)

From feed by feedfeeder

Quantum computers scarcely exist yet, but scientists havealreadybegun working on shrinking them down by creating smaller components. A group of researchers have devised a way to use an LED to generate the entangled photon pairs needed for quantum teleportation, computing, and encryption. While the LED is not quite as reliable as lasers, its smaller footprint should help make quantum applications a bit more practical.

To generate entangled pairs of photons, researchers often use a process called parametric down-conversion. A laser sends its light at a crystal that can split each individual photon in two photons that are entangled so their properties are linked to one another. This method may be popular, but still has some problems.

I need details! When will a production model be available? Range? How much will it cost? I don't like the sound of hand-assembled batteries. Is there a transmission? I need to know these things before I put it on my when-I-win-the-lottery-wishlist next to my Tesla Roadster.

Kindly direct your attention towards the MotoCzysz E1pc, a futuristic-looking electric bike that has 10 times the battery power of a Prius, 2.5 times the torque of a Ducati, and a top speed 140 MPH. For some perspective, the bike’s closest electric competitor in this week’s Isle of Man TT motorcycle competition reached a top speed of 102 MPH during practice.
