People Who Claim To Worry About Climate Change Don't Cut Energy Use 708

Posted by Unknown Lamer
from the just-build-a-few-nuclear-reactors dept.
schwit1 (797399) writes with news that a UK study has found that folks concerned about climate change don't do much to conserve power at home. From the article: Those who say they are concerned about the prospect of climate change consume more energy than those who say it is "too far into the future to worry about," the study commissioned by the Department for Energy and climate change found. That is in part due to age, as people over 65 are more frugal with electricity but much less concerned about global warming. However, even when pensioners are discounted, there is only a "weak trend" to show that people who profess to care about climate change do much to cut their energy use. The findings were based on the Household Electricity Survey, which closely monitored the electricity use and views of 250 families over a year. The report (PDF), by experts from Loughborough University and Cambridge Architectural Research, was commissioned and published by DECC. High power use doesn't have to be dirty: Replace coal, methane, and petroleum with nuclear, wind, solar, etc.

Coming Soon(ish) From LG: Transparent, Rollup Display 64

Posted by Unknown Lamer
from the animated-wall-paper dept.
jfruh (300774) writes Korean electronics manufacturer LG has shown off experimental, see-through, roll-up displays, paper thin and flexible and capable of letting through about 30% of the light that strikes it. The company is eager to sell the concept and promises it'll be arriving soon, though they've shown of similar (though less capable) technology over the past few years and have yet to bring any products to market.

Phase-Changing Material Created For Robots 35

Posted by samzenpus
from the bend-it-shape-it dept.
rtoz writes In the movie Terminator 2, the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat. The material developed by MIT researchers could be used to build deformable surgical robots. The robots could move through the body to reach a particular point without damaging any of the organs or vessels along the way. The Robots built from this material could also be used in search-and-rescue operations to squeeze through rubble looking for survivors.

New Raspberry Pi Model B+ 202

Posted by samzenpus
from the latest-and-greatest dept.
mikejuk writes The Raspberry Pi foundation has just announced the Raspberry Pi B+. The basic specs haven't changed much — same BC2835 and 512MB of RAM and the $35 price tag. There are now four USB ports, which means you don't need a hub to work with a mouse, keyboard and WiFi dongle. The GPIO has been expanded to 40 pins, but don't worry: you can plug your old boards and cables into the lefthand part of the connector, and it's backward compatible. As well as some additional general purpose lines, there are two designated for use with I2C EEPROM. When the Pi boots it will look for custom EEPROMs on these lines and optionally use them to load Linux drivers or setup expansion boards. Expansion boards can now include identity chips that when the board is connected configures the Pi to make use of them — no more manual customization. The change to a micro SD socket is nice, unless you happen to have lots of spare full size SD cards around. It is also claimed that the power requirements have dropped by half, to one watt, which brings the model B into the same power consumption area as the model A. Comp video is now available on the audio jack, and the audio quality has been improved. One big step for Raspberry Pi is that it now has four holes for mounting in standard enclosures.

Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best 129

from the enhance-enhance-enhance dept.
Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame."

Slashdot Asks: Do You Want a Smart Watch? 381

Posted by timothy
from the does-it-shoot-deadly-darts? dept.
Watches that do more than tell the time have been around for a long time. (And in fiction, James Bond, Dick Tracey, and Michael Knight all had notably high-tech watches.) The new smart watches from Samsung and LG, without a phone connected via Bluetooth as backhaul, can still serve to show the time and to serve as alarms (and Samsung's can measure your pulse, too), but all the magic features (like searching by voice via the watch) do require a connection. They can't play MP3s or take pictures on their own, and they don't have built-in GPS. Even so, compared to the polarizing Google Glass, the new breed of smart watches are wearables that probably are an easier sell, even if this far the trend has been to replace watches with smart phones. (Android Wear has gotten a lot of attention, but Microsoft has their own upcoming, and Apple almost certainly does, too.) Are you interested in a smart watch, and if so, what uses do you want it for? If they have no appeal to you now, are there functions that would make you change your mind on that front?

Sand-Based Anode Triples Lithium-Ion Battery Performance 60

Posted by timothy
from the but-where-will-it-comes-from? dept.
Zothecula (1870348) writes "Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand."

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment? 502

Posted by timothy
from the won't-fit-in-my-phone dept.
MojoKid (1002251) writes "Back in the day (which is a scientific measurement for anyone who used to walk to school during snowstorms, uphill, both ways), integrated audio solutions had trouble earning respect. Many enthusiasts considered a sound card an essential piece to the PC building puzzle. It's been 25 years since the first Sound Blaster card was introduced, a pretty remarkable feat considering the diminished reliance on discrete audio in PCs, in general. These days, the Sound Blaster ZxR is Creative's flagship audio solution for PC power users. It boasts a signal-to-noise (SNR) of 124dB that Creative claims is 89.1 times better than your motherboard's integrated audio solution. It also features a built-in headphone amplifier, beamforming microphone, a multi-core Sound Core3D audio processor, and various proprietary audio technologies. While gaming there is no significant performance impact or benefit when going from onboard audio to the Sound Blaster ZxR. However, the Sound Blaster ZxR produced higher-quality in-game sound effects and it also produces noticeably superior audio in music and movies, provided your speakers can keep up."

Apple Gets Its First Batch of iPhone Chips From TSMC 45

Posted by timothy
from the pronounced-just-like-it-looks dept.
redletterdave (2493036) notes that Taiwan Semiconductor Manufacturing Co. (TSMC) has shipped its first batch of microprocessors to Apple as the iPhone maker looks to diversify its overseas suppliers. Apple will continue to rely on Samsung for its microprocessors, but as the rivalry between Apple and Samsung heats up in the mobile and soon wearable arenas, the deal with TSMC allows Apple to be less reliant on Samsung and therefore have more leverage with respect to price negotiations for future chips, as TSMC has supplanted Samsung Electronics as Apple's chief chipmaker for iPhones and iPads. Since 2011, Apple has been striking deals with other display and chip makers around Asia to reduce its dependence on Samsung. As a result of this slowdown in sales, Samsung on Monday announced operating income for its fiscal second quarter had sunk to a two-year low, blaming 'weak' sales of low- and medium-end smartphones, strong competition and subpar demand.
It may not be a household name like Intel or AMD, but TSMC is the world's biggest chip maker by revenue.

Hacking a Tesla Model S Could Net $10,000 Prize 77

from the usb-port-under-the-gas-cap dept.
cartechboy (2660665) writes "It seems there's a new hack challenge set every week, but this time, it seems different. A challenge has been thrown down to hack a Tesla Model S with a $10,000 prize. The organizers of a computer security conference have set the challenge and it's open to anyone that registers for the Syscan conference. Taking place in Beijing from July 16-17, the rules for the hack competition haven't been revealed yet but a Model S will be on display for hackers to try their luck on. It's important to note that Tesla itself isn't involved in the competition in any official capacity, nor does it support the competition. If successful, this wouldn't be the first time a Tesla Model S has been hacked. In that instance Tesla was quick to warn people that making changes in the Model S' software would immediately void the car's warranty. Given the car's high-tech nature, it's no shock Tesla's taking security seriously. With $10,000 on the line, it'll be interesting to see if anyone manages to crack the code."

IBM To Invest $3 Billion For Semiconductor Research 68

Posted by samzenpus
from the big-bucks dept.
Taco Cowboy points out that many news outlets are reporting that IBM plans to spend $3 billion on semiconductor research and development in the next five years. The first goal is to build chips whose electronic components, called transistors, have features measuring just 7 nanometers, the company announced Wednesday. For comparison, that distance is about a thousandth the width of a human hair, a tenth the width of a virus particle, or the width of 16 potassium atoms side by side. The second goal is to choose among a range of more radical departures from today's silicon chip technology -- a monumental engineering challenge necessary to sustain progress in the computing industry. Among the options are carbon nanotubes and graphene; silicon photonics; quantum computing; brainlike architectures; and silicon substitutes that could run faster even if components aren't smaller. "In the next 10 years, we believe there will be fundamentally new systems that are much more efficient at solving problems or solving problems that are unsolvable today," T.C. Chen, IBM Research's vice president of science and technology, told CNET

mdsolar sends this story from the NY Times: Here's what your future will look like if we are to have a shot at preventing devastating climate change. Within about 15 years every new car sold in the United States will be electric. ... Up to 60 percent of power might come from nuclear sources. And coal's footprint will shrink drastically, perhaps even disappear from the power supply. This course, created by a team of energy experts, was unveiled on Tuesday in a report for the United Nations (PDF) that explores the technological paths available for the world's 15 main economies to both maintain reasonable rates of growth and cut their carbon emissions enough by 2050 to prevent climatic havoc. It offers a sobering conclusion: We might be able to pull it off. But it will take an overhaul of the way we use energy, and a huge investment in the development and deployment of new energy technologies. Significantly, it calls for an entirely different approach to international diplomacy on the issue of how to combat climate change.

How Japan Lost Track of 640kg of Plutonium 104

Posted by Soulskill
from the left-it-in-my-other-pants dept.
Lasrick sends this quote from the Bulletin of the Atomic Scientists: Most people would agree that keeping track of dangerous material is generally a good idea. So it may come as a surprise to some that the arrangements that are supposed to account for weapon-grade fissile materials—plutonium and highly enriched uranium—are sketchy at best. The most recent example involves several hundreds kilograms of plutonium that appear to have fallen through the cracks in various reporting arrangements. ... [A Japanese researcher discovered] that the public record of Japan’s plutonium holdings failed to account for about 640 kilograms of the material. The error made its way to the annual plutonium management report that Japan voluntarily submits to the International Atomic Energy Agency ... This episode may have been a simple clerical error, but it was yet another reminder of the troubling fact that we know very little about the amounts of fissile material that are circulating around the globe. The only reason the discrepancy was discovered in this case was the fact that Japan has been unusually transparent about its plutonium stocks. ... No other country does this.
