"More SCI/tech headlines": "More SCI/tech headlines"Science for science's sakeUntil Universities start offering Bachelor of Arts in Computers, IT will be equated to science. Computer Science is more like creative technical writing. Programs follow an algorithm - which is a set of rules. Literature follows a set of rules too (into, body, conclusion, other...; Tags: theory; Discussion threads 2008-04-10
Janus particles as body submarines?: Janus particles, which take their name from a Roman god with two faces, are microscopic 'two-faced' spheres whose halves are physically or chemically different. Now, U.S. researchers have shown that some of these Janus microparticles can move like stealthy submarines when an alternating electrical field is applied to liquid surrounding...; Tags: Hemisphere, Particle, Thin Clients, Hardware, Roland Piquepaille; Blog posts 2008-02-29
Nanoemulsion vaccines effective against HIV?: Nanoemulsions are non-toxic lipid droplets approved for human consumption and common food substances that are defined as 'Generally Recognized as Safe' GRAS by the FDA. But they also can be used for medical applications. Researchers at the University of Michigan have developed nasal nanoemulsion vaccines for influenza which were successfully...; Tags: Vaccine, Particle, HIV, Nanoemulsions, Healthcare, Roland Piquepaille; Blog posts 2008-02-28
A scientific Oscar goes to Stanford: On February 9, 2008, the Academy of Motion Picture Arts and Sciences will give its ten Scientific and Technical Academy Awards for the year. One of them will go to a professor of computer science at Stanford University who worked with scientists from Industrial Light & Magic. They'll receive this...; Tags: Method, Particle, Stanford, Computer, Oscar, Productivity, Roland Piquepaille; Blog posts 2008-02-04
Building 3-D particles with light: Engineers at the Massachusetts Institute of Technology MIT have used ultraviolet light to create mass-producing 3-D microparticles that could be used for medical diagnostics and tissue engineering. 'For example, they could be designed to act as probes to detect certain molecules, such as DNA, or to release drugs or nutrients.'...; Tags: 3D, Massachusetts Institute Of Technology, Particle, Biotechnology, Roland Piquepaille; Blog posts 2007-12-04

Remotely controlled nanoparticles fight tumors: Many researchers around the world have tried to use nanoparticles to battle cancer. Now, researchers from the MIT have gone a step further. They found a way to 'talk' with the nanoparticles. In other words, they can control the nanoparticles and ask them to deliver drugs directly into tumors. Strands...; Tags: Tether, Nanoparticle, Particle, Biotechnology, Roland Piquepaille; Blog posts 2007-11-17
All your hard drive are belong to us: Two California innovators cried foul when major hard drive and PC manufacturers started making billions off using their ceramic bonding invention, a critical tool needed to make these types of devices, without compensating them for their hard work. Refusing to be intimidated by the huge companies and their equally huge...; Tags: Hard Drive, Particle, Ed Burnette; Blog posts 2007-10-12
Coal pollution lawsuit settled as the whole game has changed: Coal pollution lawsuit settled as the whole game has changedYeahno one focuses on acid rain pollution anymore because it's been demonstrated to be bogus; the result of more precise measuring technology.

Photos: Voyagers--strange visitors to other planets: It was thirty years ago when the first Voyager spacecraft left Earth. The ships have returned closeup views of four planets--and aren't finished yet.Voyager 2 launched on Aug. 20, 1977, and Voyager 1 followed on Sept. 5, 1977, for what was originally a five-year mission to study Jupiter...; Tags: Earth, Moon, Data, Photograph, Voyager 1, Saturn, Neptune, Jupiter', Io, Great Red Spot, It', nnTriton, Here', Cassini, CNET News.com; Image galleries 2007-08-28
Nuking cancer cells with alpha particles?: Radiotherapy is widely used to fight cancers. Today, only beta particles are approved by health regulators, such as the U.S. FDA. Beta particles are small and travel fast, but it takes thousands of them to kill a cancer cell. Now, U.S. researchers have found a way to use alpha particles...; Tags: Rice University, Particle, Cell, Radiotherapy, Roland Piquepaille; Blog posts 2007-08-27
Nanotechnology boosts solar cells performance: Nanotechnology boosts solar cells performanceParticle sizeThe size of the particles contributes to the particular color that is emitted when it is excited by light. Particles on a nano-scale cause this effect, but as you increase the size of the particles, the color emission no longer persists. This may...; Tags: Semiconductors, nanotechnology, silicon nanoparticle, particle, Silicon Nanoparticles; Discussion threads 2007-08-21
Nanotechnology boosts solar cells performance: Physicists from the University of Illinois at Urbana-Champaign UIUC have improved the performance of solar cells by 60 percent. And they obtained this spectacular result by using a very simple trick. They've coated the solar cells with a film of 1-nanometer thick silicon fluorescing nanoparticles. The researchers also said that...; Tags: Silicon, Performance, Nanoparticle, Particle, Nanotechnology, Cell, Roland Piquepaille; Blog posts 2007-08-21
Besieged by HP's derogations, laser printer emissions whistleblower fights back: Meet Queensland University of Technology's Professor Lidia Morawski. She's the researcher that, by sheer chance, discovered that certain laser printers including a bunch from HP were emitting an unusually high volume of ultrafine particles -- so many that she deemed them to be a potential source of respiratory irritation,...; Tags: Printer, Hewlett-Packard Co., Laser Printer, Particle, Health Care, Laser, David Berlind; Blog posts 2007-08-10

ZDNet reader: If Carbon Black were really that carcinogenic, we'd all be dead: At least one ZDNet reader thinks that the laser printer emissions issue that I've been covering is much ado about nothing.On the heels of the publication of an Australian study that found certain laser printers to emit unhealthy concentrations of particles, one of the big questions is whether those particle...; Tags: Laser Printer, Particle, Laser, Carbon, David Berlind; Blog posts 2007-08-09
The physics of beer bubbles: Yesterday, I told you about virtual beer. Today, let's follow two North America researchers who are studying the physics of real beer bubbles. 'Singly scattered waves form the basis of many imaging techniques such as radar or seismic exploration.' But pouring beer in a mug involves multiply scattered acoustic waves....; Tags: Technique, Food, Imaging, Beer, Wave, Particle, Beer Bubble, Roland Piquepaille; Blog posts 2007-08-05
HP on potentially dangerous laser printer emissions: Our printers no riskier than toasters: In yesterday's blog post about the potentially dangerous laser printer emissions that were uncovered by Queensland University of Technology in Australia, I noted that HP's LaserJets bore the brunt of the study's findings and that I'd follow up when HP delivered the response it promised. That response showed up in...; Tags: Printer, Hewlett-Packard Co., Laser Printer, Particle, Health Care, Laser, David Berlind; Blog posts 2007-08-03

Faster slamming robots: Im not speaking here of noisy robots. SLAM is an acronym for simultaneous localization and mapping, and slamming robots are simply robots which at the same time build a map of their environment while keeping track of their own localization.
