Charlyrobot of France is launching its new generation of Computer Numerical Control (CNC) mini-milling machines, for compact 3D milling, called Charly4U. Charlyrobot has been a leading manufacturer of milling machines for more than 20 years. The company has local partners in the UK but is looking for distributors in the Nordic Region. Charlyrobot will be showcasing its technology at the Euromold trade show in Frankfurt in early December 2004.
Thanks to Charly4U, Charlyrobot is s
Before you pop that cookie in your mouth, take a moment to consider how long it will take to burn off those extra calories.
If you eat two cookies, about 150 calories, and you weigh about 140 pounds, you’ll have to walk more than an hour at a pace of 2 miles an hour to burn off those cookies. Speed up the walk to 3.5 mph, and you still have to walk 45 minutes. (Eating the cookies probably took less than a minute.) What if you ate a peach, with about 40 calories, instead? It would ta
One of the most promising drugs on the market today is neither new nor revolutionary. You can even buy it over the counter. What is it? Aspirin.
The November issue of Mayo Clinic Women’s HealthSource covers new and not-so-new uses for this 107-year-old medication. In addition to being a fever reducer, headache tamer and arthritis soother, aspirin is now commonly used to prevent heart attacks and strokes. Aspirin also is gaining credit for possibly helping to prevent some types of
Researchers at the Technion-Israel Institute of Technology have developed three drugs to remove excess iron from the brains of patients with neurodegenerative diseases. The presence of too much iron in the brain is a hallmark of such diseases. The drugs, VK-28, HLA-20 and M30, mop up the iron before it can trigger a “brain rust” chemical reaction where highly active oxygen particles destroy brain cells.

In August and September of this year, three powerful icebreakers transited to the North Pole in search of a climate record stored in sediments below the Arctic Ocean floor. During the spectacular Arctic Coring Expedition (ACEX), conducted by the Integrated Ocean Drilling Program (IODP), 340 meters of sediment core were retrieved from the bottom of the Arctic Ocean — a true “first.” With these sediments in hand, earth scientists for the first time can move away from pure speculation about the
Cornell University researchers, who are trying to understand how proteins evolve and function by looking at their structural features, have uncovered the crystal structure of a protein involved in making the building blocks of DNA correctly.
The protein is AIRs kinase, and to the researchers’ surprise, its shape is similar to other members of the riboside kinase family, proteins that are important in making DNA and RNA, the molecules that make up genes. As a result, the rese
Researchers at the University of Pennsylvania School of Veterinary Medicine have identified the growth factors essential to allow spermatogonial stem cells — the continually self-renewing cells that produce sperm — to exist in culture indefinitely. Their findings will be presented this week in the Proceedings of the National Academy of Science online Early Edition.
After being kept in culture for three months, the stem cells restored sperm production, and therefore fertil
Human activity causes 10 times more erosion of continental surfaces than all natural processes combined, an analysis by a University of Michigan geologist shows.
People have been the main cause of worldwide erosion since early in the first millennium, said Bruce Wilkinson, a U-M professor of geological sciences. Wilkinson will present his findings Nov. 8 at a meeting of the Geological Society of America in Denver, Colo.
Many researchers have tried to assess the im
Loyola University Health System begins today the national clinical trial using PolyHeme®, an investigational oxygen-carrying blood substitute designed to increase survival of critically injured and bleeding trauma patients at the scene of injury. Loyola has been involved in extensive public education, staff education and paramedic training since its Institutional Review Board for the Protection of Human Research Subjects (IRB) approved the clinical trial in May. Loyola is one of 20-25 Level
A critical benchmarking test indicates that a processing-in-memory (PIM) chip designed and prototyped at the University of Southern California’s Information Sciences Institute is delivering the speedup designers hoped.
A team of ISI computer scientists led by software specialist Mary Hall and chip designer Jeff Draper earlier this year successfully integrated the new PIM chip, called “Godiva,” into a Hewlett-Packard Long’s Peak Server. Hall and Draper will discuss their work at th
USC study shows brachytherapy holds promise as treatment for once-debilitating cancers
Brachytherapy, the administration of radiation therapy locally through radioactive seeds, holds promise as part of a limb-sparing treatment program for patients with soft-tissue sarcomas, according to researchers at the Keck School of Medicine of the University of Southern California. After five years, 83 percent of patients in a trial incorporating brachytherapy into the treatment plan had survi
Leading experts address need to reduce risk to global blood supply
There is increasing evidence that infectious prions that can cause variant Creutzfeldt-Jakob Disease (vCJD), the human form of “mad cow” disease, can be transmitted through blood transfusion, according to Roger Eglin, Ph.D., Head of National Transfusion Microbiology Laboratories for the English National Blood Service. He spoke at a symposium on Transmissible Spongiform Encephalopathies (TSEs) where he was joined b
Radiofrequency ablation (RFA), the use of electrodes to heat and destroy abnormal tissue, is a safe and effective treatment for eradicating liver tumors that are in contact with the gastrointestinal (GI) tract, says one study in the November 2004 issue of the American Journal of Roentgenology, while a separate study in that same issue says that RFA becomes even more effective when alcohol is injected into a liver tumor before an RFA procedure.
In the first study, researchers from
The first test in humans of a bioartificial kidney offers hope of the device’s potential to save the lives of people with acute renal failure, researchers at the University of Michigan Health System report.
While the phase I/II study was designed primarily to look at the safety of using this device on humans, the results also suggest improvement in kidney function. The patients enrolled in the trial faced an average 86 percent likelihood of dying at the hospital. Six of those 10
Tools so tiny that they are difficult to see, are solving the problems of carving patterns in glass, ceramics and other brittle materials, according to a Penn State engineer.
“Even very brittle materials like glass will cut smoothly at a micron level,” says Dr. Eric R. Marsh, associate professor of mechanical engineering. “The tools we are making are small enough so that the brittle materials behave like a malleable material like aluminum, producing smooth curly chips of glass or
Illnesses and injuries leading to hospitalization or restricted activity are key sources of disability for independent older persons, regardless of physical frailty, Yale researchers report in the November 3 issue of JAMA.
“The risk of developing disability within a month of hospitalization was elevated more than 60-fold, while the risk of developing disability within a month of restricted activity was elevated nearly six-fold,” said principal investigator Thomas M. Gill, M.D.,
