Submission + - The Evidence Supports Artificial Sweeteners Over Sugar->

schwit1 writes: In the last few years, I've watched a continuing battle among my friends about which is worse for you: artificial sweeteners or sugar. Unless you want to forgo all beverages that are sweet, you're going to run into one of these. Rather than rely on anecdote or myth, we can inform this debate with research.

The available evidence points to the fact that there appears to be a correlation between sugar consumption and health problems; none can be detected with artificial sweeteners.

Submission + - Currently Quantum computers might be where Rockets were at the time of Goddard->

schwit1 writes: If quantum computing is at the Goddard level that would be a good thing for quantum computing. This means that the major fundamental breakthrough that would put them over the top was in hand and merely a lot of investment, engineering and scaling was needed.

The goal of being able to solve NP-hard or NP-Complete problems with quantum computers is similar to being able to travel to the moon, mars or deeper into space with rockets. Conventional flight could not achieve those goals because of the lack of atmosphere in space. Current computing seems like they are very limited in being able to tackle NP-hard and NP Complete problems. Although clever work in advanced mathematics and approximations can give answers that are close on a case by case basis.

Submission + - State Of Georgia Sues for Copyright Infringement For Publishing The State's Laws-> 1 1

schwit1 writes: The state of Georgia has sued sued Carl Malamud and his site Public.Resource.org. It is about as ridiculous as you would expect focusing on the highly questionable claim that the Official Code of Georgia Annotated is covered by federal copyright law — and that not only was Malamud (*gasp*) distributing it, but also... creating derivative works! Oh no! And, he's such an evil person that he was encouraging others to do so as well!

Submission + - Stretchable Conducting Fiber Provides Super Hero Capabilities->

schwit1 writes: The list of potential applications for a new electrically conducting fiber-artificial muscles, exoskeletons and morphing aircraft-sounds like something out of science fiction or a comic book. With a list like that, it's got to be a pretty special fiber... and it is. The fiber, made from sheets of carbon nanotubes wrapped around a rubber core, can be stretched to 14 times its original length and actually increase its electrical conductivity while being stretched, without losing any of its resistance.

Submission + - Metal Foam: radiation shielding that's lighter and twice as effective as Alumin->

schwit1 writes: North Carolina State University researchers have found that lightweight composite metal foams they had developed are effective at blocking X-rays, gamma rays, and neutron radiation, and are capable of absorbing the energy of high-impact collisions. The finding holds promise for use in nuclear power plants, space exploration, and CT-scanner shielding.

This work means there's an opportunity to use composite metal foam to develop safer systems for transporting nuclear waste, more efficient designs for spacecraft and nuclear structures, and new shielding for use in CT scanners

Submission + - Nanostructured Glass Can Switch Between Blocking Heat and Blocking Light->

schwit1 writes: Electrochromic glass essentially uses electric charge to switch a window from allowing sunlight in to blocking it out. Some have estimated that such "smart windows" could cut lighting needs by about 20 percent and the cooling load by 25 percent at peak times.

Now researchers at the University of Texas Austin have found a way to make them even better. They developed a novel nanostructure architecture for electrochromic materials that enables a highly selective cool mode and warm mode-something thought to be impossible a few years back.

Submission + - SOLVING THE BLOOD SHORTAGE BY draining the dead?->

schwit1 writes: Roughly 15 million pints of blood are donated each year by approximately 9.2 million individuals. Over the course of the same year, about 2.6 million Americans will — sadly — pass away. If hospitals were to harvest the blood from a third of those people, roughly 4.5 million liters would be added to the reservoir. . . . Draining the blood from a body is hardly out of the ordinary; it's actually a regular part of the embalming process. To prepare a dead body for funeral services and eventual burial or cremation, morticians pump out all of the blood and interstitial fluids and replace them with an embalming solution, typically containing formaldehyde and methanol. Would it not make more sense to remove the blood at the hospital soon after death, rather than let it all go to waste?

Submission + - Remote control of a car, with no phone or network connection required

Albanach writes: Following on from this week's Wired report showing the remote control of a Jeep using a cell phone, security researchers claim to have achieved a similar result using just the car radio. Using off the shelf components to create a fake radio station, the researchers sent signals using the DAB digital radio standard used in Europe and the Asia Pacific region. After taking control of the car's entertainment system it was possible to gain control of vital car systems such as the brakes. In the wild, such an exploit could allow widespread simultaneous deployment of a hack affecting huge numbers of vehicles.

Submission + - Techies hire witch to protect computers from viruses and offices from spirits->

schwit1 writes: Many people have had their computer or smartphone possessed by an evil demon — or at least that's what it can feel like when some mysterious bug keeps causing an app to crash, or your phone keeps shutting off for no reason.

But if you truly think your electronics have been invaded by an evil spirit, there's someone who will take your call — Reverend Joey Talley — a Wiccan witch from the San Francisco Bay Area who claims to solve supernatural issues for techies.

Submission + - Plastic Roads Sound Like a Crazy Idea, Maybe Aren't->

schwit1 writes: America has an infrastructure problem. Part of that problem is our roads, which are either in terrible condition or in the process of being torn up by road crews who'll make them betterâ"until, that is, they're in terrible condition again. It's time to try something radical, and for that, we (as always) look to the Dutch for inspiration.

A Dutch construction company called VolkerWessels is partnering with the city of Rotterdam to create a prototype for a prefabricated plastic road. If it works, it would be durable, fast to construct, and way better for the environment than asphalt.

VolkerWessels' PlasticRoad concept is ambitious, to say the least. They envision pulling waste plastic out of the oceans, and then processing it into prefabricated sections of road with integrated utility channels and drainage. The composition and structure of the plastic makes it more durable than traditional asphalt, and VolkerWessels estimates that their plastic roads should last about three times as long as traditional roads.

Now make them out of photovoltaic material.
