Full Body 3-D CT Scan in Under a Minute

Pretty cool new gadget, though probably out of the range of most people’s budget – ‘Super’ scanner shows key detail

The new 256-slice CT machine takes large numbers of X-ray pictures, and combines them using computer technology to produce the final detailed images. It also generates images in a fraction of the time of other scanners: a full body scan takes less than a minute.
…
Because the images are 3D they can be rotated and viewed from different directions – giving doctors the greatest possible help in looking for signs of abnormalities or disease.
…
At present, it is only being used in one hospital: the Metro Health medical centre in Cleveland, Ohio, which has been using it for the past month.
…
the first commercially viable CT scanner, which was invented by Sir Godfrey Newbold Hounsfield in Hayes, United Kingdom at the company’s laboratories and unveiled in 1972. At the same time, Allan McLeod Cormack of Tufts University independently invented a similar machine, and the two men shared the 1979 Nobel Prize in Medicine. “This is a quantum shift from the first CT scanners as it gives a lot more detail,” says Dr Keith Prowse, Chairman of the British Lung Foundation.

Six Cool Ideas

Six Ideas That Will Change the World

The Pollution Magnet – Eighty-two thousand people die from cancer in Bangladesh every year, many due to arsenic poisoning. But building upon her discovery of a way to get rust nanoparticles to bind to arsenic, Vicki Colvin has invented a new, astonishingly easy way to clean the water supply: SautÃ© a teaspoon of rust in a mixture of oil and lye, which breaks down the rust into nano-sized pieces. Retrieve the rust particles with a household magnet. Then immerse the rust-covered magnet into a pot of contaminated water. Pull out the arsenic. The system is up to a hundred times more efficient than existing methods, and requires no electricity or manufacturing infrastructure, so even the poorest of villagers can use it.

Depending upon government regulations, Colvin’s extraction system should go global in as few as five years. Yet ultimately, Colvin, a professor of chemistry and chemical and biomolecular engineering at Rice University, has bigger plans. She sees her method as just the first step toward developing an easy point-of-use water-purification system that would cover virtually every pollutant. The filter would have a dipstick to tell you what’s in the water and a reader to tell you what you need to add to pull it out — perhaps silver nanoparticles to kill bacteria or a protein to capture pesticides.

Robot Boats Hunt Pirates

Robot Boats Hunt High-Tech Pirates on the High-Speed Seas

The International Maritime Bureau is tracking a 14-percent increase in worldwide pirate attacks this year. And although modern-day pirates enjoy collecting their fare share of booty—they have a soft spot for communications gear—they’re just as likely to ransom an entire ship. In one particularly sobering case, hijackers killed one crew member of a Taiwan-owned vessel each month until their demands were met.

For years now, law enforcement agencies across the high seas have proposed robotic boats, or unmanned surface vessels (USVs), as a way to help deal with 21st-Century techno Black Beards. The Navy has tested at least two small, armed USV demonstrators designed to patrol harbors and defend vessels. And both the Navy and the Coast Guard have expressed interest in the Protector, a 30-ft.-long USV built by BAE Systems, Lockheed Martin and Israeli defense firm RAFAEL.

The Protector, which comes mounted with a 7.62mm machine gun, wasn’t originally intended for anti-piracy operations. But according to BAE Systems spokesperson Stephanie Moncada, the robot could easily fill that role.

Google’s Secret 10GbE Switch

Google’s Secret 10GbE Switch, interesting speculation by Andrew Schmitt:

Through conversations with multiple carrier, equipment, and component industry sources we have confirmed that Google has designed, built, and deployed homebrewed 10GbE switches for providing server interconnect within their data centers. This is very similar to Google’s efforts to build its own server computers (excellent article here). Google realized that because its computing needs were very specific, it could design and build computers that were cheaper and lower power than off the shelf alternatives. The decision to do so had a profound impact on server architecture and influenced the market’s move to lower power density solutions that Sun (JAVA) , Intel (INTC) and AMD (AMD) now embrace.

One Laptop Per Child – Give One Get One

photo of One Child One Laptop

Why you should buy an OLPC XO Laptop:

The laptop hardware is really impressive. This laptop is really small – dimensions are 242mm Ã— 228mm Ã— 32mm (9.5″ x 9″ x 1.25″) and weight is about 1.5KG (3.3 lbs). There is a 7.5″ 200dpi high resolution display capable of displaying 1200×900 pixels in grayscale (usable in direct sunlight!) or 800×600 in colour. The processor is relatively low-powered, but probably fine for the types of things most people will use this laptop for. There is no hard drive (storage is 1GB of flash which you could increase with USB drives or memory sticks or an SD card if you needed to), a rubber membrane water resistant keyboard, gamepad, touchpad, audio, built-in camera, integrated wireless (both 802.11b/g and 802.11s “mesh” networking support), a long-life battery (I’ve heard different stories, but it sounds like battery life will go into the double digits!), rechargeable with AC/DC power, solar or hand/foot generator, etc. On top of all this, the laptop is the most energy-efficient and environmentally-friendly laptop ever made!
…
The OS is a paired-down version of Fedora Linux with a custom Sugar graphical user interface and Bitfrost security platform. There are programs for internet browsing, chat, wikis, word processing, and most other “standard” things you would need to do on a laptop (as well as “non-standard” utilities for things like music synthesis/composition, drawing, games, etc). The standard programming environment consists of Python, Javascript, Etoys (Squeak/Smalltalk), Csound, LOGO, and others.

We mentioned the Give One Get One program last month – you can buy one for yourself with the purchase of one for a child in the developing world. The cost is $400, $200 qualifies as a charitable deduction (the gift for the child). That offer is available now (for the next 12 days). One of our popular posts recounted what kids in India learned using a computer.

New “Cold Cathode” Fluorescents: 4 Times Longer Life, Reduced Mercury

New “Cold Cathode” Fluorescents: 85% Less Mercury

It’s a new fluorescent bulb that could have a bright future — the cold cathode fluorescent lamp (or CCFL). These bulbs contain half the mercury of conventional “hot cathode” fluorescents. They have a thinner tube diameter, which allows them to run cooler, and last up to four times as long (a lifespan of 25,000 hours). This means that the mercury is reduced by 85% over the life of a cold cathode bulb, because a regular CFL would have to be replaced three times during that period. Another big advantage of CCFLs is that they are fully dimmable, and “on/off” cycles do not shorten their life.

Sandwich Brick – Reusing Waste Material

A brick-through, Malaysia

at the British Invention Show 2007 held in London recently, waste material bagged Universiti Malaya (UM) researcher Asrul Mahjuddin Ressang Aminuddin a Diamond (Special Award for Earth Science). The lecturer, from UM’s Built Environment faculty, designed a “sandwich brick” that incorporated unwanted plastic, wood particles and other waste material at its core. Helping to save about 26% to 30% on construction costs, the sandwich brick promotes green architecture in the built environment.

“I first came up with the idea when I was assisting the tsunami victims in Thailand and Indonesia,” said Asrul Mahjuddin Ressang. “There was a lot of debris lying around and I wondered how if any could be used for rebuilding purposes.” The brick design has been well received by British construction companies as it is not only environmental friendly but is also entitled to tax incentives across Europe.

It also provides a solution to Britain’s hard-pressed construction industry following the ban on sand mining from riverbeds and waste accumulation that stands at 15 million tonnes in 2007 alone. The innovation impressed judges as it had better heat insulation compared to ordinary bricks and encouraged industries to rethink recycling at minimal costs.
…
Meanwhile, engineering faculty senior lecturer Dr Mohd Hamdi Abd Shukor received a Double Gold (Special Award for Industry) – for his work on tough synthetic bio-ceramic for bone implant technology and a minimal cutting fluid application in a pulse jet form.

New and Old Ways to Make Flu Vaccines

New and Old Ways to Make Flu Vaccines by Nell Greenfieldboyce, NPR:

Standard Practice
Pros: Millions of Americans receive this [standard] vaccine every year. It’s safe and well tolerated. Its production begins in hens’ eggs — a tried and true technology for 50 years.
Cons: Eggs must be ordered many months in advance, and millions of doses require millions of eggs.

Live-Attenuated Vaccine
Pros: This newer method of production results in a vaccine that has a flu virus that is crippled, so it can’t cause disease. But the virus is not killed, as is the case in the standard vaccine. The vaccine also can be given as a nasal spray.
Cons: More expensive than standard vaccine, and also produced in eggs. Not approved for young children or older people.

Cell-Based Vaccine
Pros: This vaccine can be produced in giant vats of living cells. Such a production method means it can be scaled up much faster than egg-based vaccines, making it more useful in a pandemic. Several versions have been tested successfully in people.
Cons: Won’t be widely available for a few years. Clinical trials are under way, but no flu vaccine made this way is currently approved by the Food and Drug Administration.

Home Use Vertical Axis Wind Turbine

Photo of Winterra Turbine

The Windterra ECO1200 Wind Turbine is a revolutionary Vertical Axis Wind Turbine (VAWT).

Omni-directional: The ECO1200 can instantaneously accept wind from any direction as opposed to HAWTs (Horizontal Axis Wind Turbines, which require an on-board motor to rotate the unit relative to wind direction.
Turbulent-wind friendly: The ECO1200 is easily roof mountable and is less affected by turbulent air, making ECO1200 suited for areas where houses and trees may disturb airflow.
All-in-one system: The ECO 1200is a complete power-generation package, including turbine, controller/inverter, and mounting system. This system can typically be installed and ready to use in four to five hours.
Roof-top mounting: The ECO1200 is designed for roof top use, eliminating the need for a pole or tower installation that significantly increase cost and complicate routine maintenance.

Interesting looking. Based on some of the figures on their site it seems like this is still pushing the economic justification but with more and more engineers improving such similar system hopefully wind power can meet more of our energy needs over time.
