Extreme Yo-Yoing
Roland Piquepaille writes "Unless you're a dedicated yo-yo fan and a serious competitor, I doubt that you'll hand over $400 for a yo-yo. Even if it's a state-of-the-art hogh-tech yoyo made with a forged-magnesium-alloy and coming with the latest in axle technology. With this one, you can use the freehand style, meaning that your hand is not connected to the yo-yo, but is replaced by a small counterweight. In 'Reinventing the Yo-Yo,' Science News Online says 'its balance is ensured with precision tooling to micrometer tolerances by a computer-controlled lathe.' This long article doesn't solely focus on this luxury item. Instead, it looks at the history and the physics of the yo-yo, and includes many references. A good read for a weekend! This overview contains other details and extra references about the Freehand yo-yo." -

Space Technology to Conquer Everest
Roland Piquepaille writes "These days, the European Space Agency (ESA) is busy sharing its space technologies. Last week, in "Space technology hits the slopes," it said that the ski maker Rossignol hopes to beat the world speed skiing record of 250 km/h by using skis stabilized by a mechanism developed for ESA's Rosetta spacecraft. And today, the ESA announced that a satellite-based Health Monitoring Kit developed by the Canadian company March Networks and co-funded by ESA, will help climbers to escalate Everest. Of course, this kind of technology can be applied at lower altitudes. This overview contains other details and references about the March Networks Health Monitoring Kit." -

RFID Coming To A Cell Phone Near You
Roland Piquepaille writes "In "RFID Goes Mobile", Red Herring reports that Nokia has quietly launched last month the first RFID-enabled cell phone. The Mobile RFID Kit will be available later this year and only for the 5140 model. This accessory allows the user to easily launch services and conveniently access phone functions simply by touching the phone to an RFID tag. The phone accesses the RFID tag data when an RFID reader emits a short-range radio signal that powers a microchip on the tag, allowing the ID information and other stored data to be read. Nokia doesn't intend to sell this kit to ordinary consumers like you and me. Instead, the RFID kit is designed to extend the mobility of workforce already on the move, such as security guards or maintenance people. This overview contains other details and references about the kit." -

The 'Pervasive Computing' Community
Roland Piquepaille writes "Most of us are using computers, but also PDAs and cell phones. And this trend is accelerating in our increasingly networked wireless world. We might use hundreds of computing devices by the end of this decade. Still, we are slaves to our machines. With every new device, we have to learn new commands, languages or interfaces. The Cambridge-MIT Institute (CMI), a strategic alliance between the University of Cambridge in the UK and the Massachusetts Institute of Technology in the U.S., has enough of it and wants to give back control to the users. So it launched its 'Pervasive Computing' initiative with the intention to tackle this challenge. In particular, the group wants to develop new technologies to make easier for us to interact with all these computers. This overview contains more details and references about this initiative." -

Pearl, a Robot for the Elderly
Roland Piquepaille writes "The world population is rapidly aging -- at least in developed countries. The number of seniors will explode in the next two decades. So researchers everywhere are trying to find new ways to help elderly people to continue to live at home. This is why a team from Carnegie Mellon, the University of Pittsburgh, University of Michigan and Stanford University has spent the last four years to design Pearl, a robot specifically designed to help old people. Pearl has a humanoid aspect and is 4-feet high. Still, don't rush to the store to buy one for your old folks. It costs more than $100,000 and is not entirely ready for mass production. This overview contains more details and references. It also includes two pictures of the -- quite cute -- Pearl." -

The Heavyweight Sea Snail
Roland Piquepaille writes "Scotland, like many European countries, must comply with regulations requiring that a mandatory percentage of the energy it uses comes from renewable sources. For Scotland, this percentage will be 18% in 2010 and 40% by 2020. One of the programs in development is Ian Bryden's sea 'Snail' program. The Snail is a 30-ton anchoring device which uses hydrofoils -- wings that 'fly' in the water -- to generate enough power from tidal waves to service 10,000 homes by 2007. This overview contains more details and a picture of a prototype of the Snail with its six wings." There are several mentions of this in UK newspapers and the Scottish government webpages. -

Why We Need a Second Moore's Law
Roland Piquepaille writes "In its April issue, Wired Magazine argues that we need a second Moore's law, this time about overall efficiencies of our computers and other electronic devices. The subtitle of the article summarizes it: "If we don't do something about increasing battery life, we're toast." Michael S. Malone, the author, says that the first Moore's law is endangered, not because the semiconductor industry cannot build new generation of chips, but because we will not be able to provide them with enough power. And he contends that the problem arises from the fact that we are using more and more wireless devices, which obviously are not connected to a plug. This overview contains selected excerpts of this eye-opening article." -

Bicycle Riding on Square Wheels
Roland Piquepaille writes "Before starting our long working week, let's relax with this story of a bicycle with square wheels. No, it's not a joke. And it even rides smoothly. But there is a trick: the road must have a specific shape. The Math Trek section of Science News Online tells us more about this strange bicycle -- actually a tricycle with two front wheels and one back wheel. Read this overview for some excerpts and a picture of the tricycle, or the original article for an additional animation." -

Searching by Shape...
Roland Piquepaille writes "Tired to type keywords in a general search engine to retrieve an image? A solution is in view. A specialized search engine developed by engineers at Purdue University allows users to draw a sketch of a part or to select one from a database. The system then returns parts having similar shapes. They call it shape searching. They think that companies having huge databases containing existing parts, such as in the automotive or the airline industries, will be able to save millions of dollars annually by saving up to 80 percent of the time necessary to search information on parts. This overview contains more details and an illustration of the searching process." -

May The Force (of Mayonnaise) Be With You!
Roland Piquepaille writes "A team of chemists at Rice University was working last year on two separate projects: trying to create strong fibers from carbon nanotubes, and testing emulsions of oil and water. And they discovered that a force known as 'negative first normal stress difference' was present in both solutions. The next step was to go to a grocery store and buy a more common emulsion, namely a jar of mayonnaise. And bingo! This force was also at work. They tell us more in this news release, "Bizarre Attractive Force Found in Mayonnaise." Unfortunately, they don't know what to do from their findings. Still, it's fun science. More details and references are available in this overview." -

Plone 2.0 Released
Alexander Limi writes "Over a year in development, the Plone Team released the 30+ language strong Plone 2.0 to the public today. It's been a fun year, with a number of surprises - coming out on top of O'Reilly's Open Source at COMDEX vote, powering the Mars Rover site and a lot of positive mainstream press. And the invaluable recognition of becoming recognized as a real word by Google *wink*. A detailed summary of what's new in the 2.0 release is available, and as usual all platforms have dedicated packages/installers that will get you up and running in 10 minutes. Enjoy!" -
Will You Ride This Nano-Elevator?
Roland Piquepaille writes "Chemists from Italy and at the University of California, Los Angeles (UCLA) have built the world's smallest elevator. It is a molecular elevator, about 2.5 nanometers high and 3.5 nanometers wide. The molecular platform sits on three legs which can move up and down by one nanometer. The New Scientist and the New York Times (free registration needed) are both reporting about this nano-elevator. The researchers think this system might be used as a drug delivery system. Even if they're right, it will not happen before at least ten years. This overview contains some excerpts from the two articles mentioned above. It also includes a schematical representation of the chemical equilibrium between the two co-conformations of the molecular elevator." -

The Arrival of Very Small Memory
Roland Piquepaille writes "After the ages of DRAM and SRAM memories, is this time for nanotech memories? ExtremeTech says that "molecular memories" as well as memories based on carbon nanotubes are emerging. With these nanotech memories, several startup companies are envisioning future chips mixing logic, memory and reconfigurable computing elements. One of these promising startups is ZettaCore, which has built a prototype of a molecular memory designed to replace both SRAM and DRAM kinds of memories. These molecules, which are about 1 nanometer in size, are also self-assembling, meaning that they can be manufactured with existing equipment used in the semiconductor industry. This overview contains more details about the technology and includes a diagram of these molecules in a memory array." -

Meet Lucy, The Orangutan Robot
Roland Piquepaille writes "Lucy is not an ordinary robot, driven by software. She's a pure product of artificial intelligence (AI). And after a three-year long training, she's now able to make a difference between an apple and a banana, which is quite handy for an orang-utan, even if she doesn't eat them. Her five microcontroller chips wouldn't like this... In "A Grand plan for brainy robots," BBC News Online tells us that Lucy is the brainchild of Steve Grand, an honorary research fellow at Cardiff University's School of Psychology. And why did he choose an orang-utan design? "I made Lucy as an orang-utan because, can you imagine how scary it would be if she looked like a human baby?," said Grand. More details and references are available in this overview which also includes the cover of Grand's last book, 'Growing Up with Lucy: How to Build an Android in Twenty Easy Steps,' which was already reviewed on Slashdot." -

Catching (Real) Viruses With Silicon
Roland Piquepaille writes "Researchers in Iowa have used nanotechnology to develop a very small silicon chip to catch and help identify viruses, according to Technology Research News. The device, dubbed the ViriChip, is used in conjunction with an atomic force microscope (AFM). The prototype is already able to identify several viruses and should be in labs in less than two years. A particular application could help save lives by enabling doctors to check a donor heart for potential infections before transplanting it to a patient. This overview contains more details. It also includes references to other articles about the ViriChip and images showing how it looks and a virus it detected." -

Stretchy Wires to Create Artificial Nerves
Roland Piquepaille writes "Researchers from the Johns Hopkins University have built electronic circuits which exhibit a rubbery behavior. The flexible circuits, built by using gold springs, can stretch like rubber. And Nature says that these stretchy wires can be used to create artificial nerves bending inside our bodies or wearable electronics. 'Wiring like this could be woven into stretchy sports clothing and used to connect up sensors that monitor athletic performance. Rubbery electrodes made from biocompatible materials might be attached to a beating heart and used to sense impending problems.' This overview contains more details and references about these flexible wires." -

Robotcop III Set to Fight Crime in Hong Kong
Roland Piquepaille writes "There is a new cop patrolling the streets of Hong Kong and teaching children how to prevent crime. But it's a robot named Robotcop III, designed and built in Hong Kong, according to Channel Newsasia. Robotcop III can walk, dance, move in any direction, display videos and answer questions asked in Cantonese and English. The previous versions of Robotcops, introduced in 1988 and 1995, were imported from the U.S. and taught 800,000 school children how to fight crime. The promoters of Robotcop III hope it will do even better. More details and references are available in this overview including a photo of Robotcop III patrolling on Hong Kong University of Science and Technology (HKUST) campus." -

Doc Searls On Fixing Tradeshows
zachlipton writes "Almost everyone seems to have a love/hate relationship with tradeshows, the giant geek, suit, and vendor gatherings put on by a handfull of corperations. Doc Searls writes in this month's LinuxJournal on his suggestions for fixing tradeshows. The problem, as he puts it, is that traditional shows make two assumptions: 'what matters most is helping vendors sell stuff to customers' and 'knowledge flows top-down, from speakers to audiences.'" -
Banryu, Robot Or Dragon?
Roland Piquepaille writes "When Yoichi Takamoto, president of the small Japanese company Tmsuk, decided to build a robotic guard for your house, he was not able to use the familiar design of a dog. The idea was already taken by Sony, with its successful Aibo. Instead, he decided to develop the Banryu (or "guard dragon") robots. After all, nobody has ever seen a real dragon. So he was free to design it as he wished. The result is a scary robot which is 90 centimeters tall, weighs 35 kilograms, has more than 50 built-in sensors and can transmit an alarm to its master's cell phone if someone tries to invade the house. It doesn't come cheap. The price is about $18,000, but you can choose between five colors. The Asahi Shimbun tells us the story, while this overview includes several pictures of the frightening dragon." This is scary? -

Meet the Nasalnaut
Roland Piquepaille writes "George Aldrich works at NASA and is not an astronaut. Instead, he's a 'master sniffer.' He tests everything that goes up in space on the shuttle or on the ISS for smelliness, from tennis shoes to teddy bears, and from refrigerators to socks or mascara. Why? Because things smell different in spacecrafts which experience a full day/night cycle every 90 minutes. And bad odors into a spacecraft can even lead to the abortion of a mission, like it happened to a Russian mission back in 1976. Wired Magazine tells us more about NASA's nasalnaut, a man whose colleagues call "Most Smella Fella" and has performed 771 flawless smelling missions. This overview contains more details and selected excerpts from a previous interview with Aldrich given to New Scientist. It also includes a picture showing how the NASA's nasalnaut smells things." -

Carbon From Outer Space Older Than Our Sun
Roland Piquepaille writes "While looking at interplanetary dust particles (IDPs) found in the Earth's stratosphere, researchers from the Washington University in St. Louis have found carbon older than the Solar System. They identified the organic material by its carbon isotopic composition, different from the one of carbon found on Earth. "Our findings are proof that there is presolar organic material coming into the Solar System yet today," said Christine Floss, the leading scientist. "This material has been preserved for more than 4.5 billion years, which is the age of the Solar System. It's amazing that it has survived for so long." This overview contains more details and references. It also contains pictures including the one of a sample's isotopic structure at a sub-micrometer scale." -

Weighing An Attogram
Roland Piquepaille writes "Researchers at Cornell University have reached a new level of precision by measuring objects with a mass of less than an attogram (10^-18 gram). They used a silicon cantilever oscillator to measure small dots of gold. But their real goal is to detect and identify viruses. The team also wants to reduce the size of the cantilever, extending the sensitivity well into the zeptogram (10^-21 gram) range. This summary contains more details and an image of a small gold dot resting on the silicon cantilever they used to achieve this breakthrough." -

Roland Piquepaille writes "The Chicago Police Department (CPD) is the sole winner of the 2004 Grand CIO Enterprise Value Award for its data warehouse and application suite. In Taking IT to the Street, the magazine writes that Chicago police officers have an immediate access to more than to 200 GB of data and nearly 8.5 million records of arrests and other incidents. It took $45 million and 3 years to the CPD to build this database with the help of Oracle, but the return on investment is huge, with labor savings of $88 million from 2001 through 2003. And while the national crime rate rose 2 percent from 2000 to 2001, Chicago rates have dropped 16 percent in the last three years. So all this information can and does prevent crime and save lives, but in Police Power Coming Up Behind You, the author reports he is somewhat worried that all these tools could fall into wrong hands. This overview contains selected excerpts and comments about this long article." -

Storing Light In Chips
Roland Piquepaille writes "Recently, researchers have "stopped light" by storing light pulses in hot or extremely cold gases (check these former stories on Slashdot or at BBC News Online). Now, scientists from Stanford University have devised a method to store light pulses under ordinary conditions. In Light-storing chip charted, Technology Research News says this opens the way for all-optical communications switches, quantum computers and quantum communications devices. The researchers plan to demonstrate this technique by trapping microwave signals within a year. They think that a prototype which works at optical frequencies could be made in two to five years. This overview contains more details and references." -
