Top Technology Stories of 2003

Nanoparticles Pop Up Everywhere 

Manipulating particles to make tiny machines or materials with strange new properties has been around for a considerable length of time, yet 2003 saw a whirlwind of achievements. IBM built up a system for influencing carbon nanotubes to radiate light, making ready for new fiber optics; Harvard researchers made sense of how to store minor wires on glass or plastic, opening the entryway for the advancement of supercheap PCs; and at the University of Central Florida, neuroscientist Beverly Rzigalinski found a nanomolecular wellspring of youth impact: When Rzigalinski connected cerium oxide nanoparticles to rodent neurons in a petri dish, the particles appeared to strip out the free radicals that influence tissues to age and kept the neurons alive and working up to six times their typical life expectancy. 

In the interim, nanomaterials are quickly invading regular day to day existence. Wilson, the donning products maker, has nanoengineered layers of dirt to twofold the playing life of its Double Core tennis balls; L'Oréal utilizes nanoscale particles and cases in their restorative creams that permit renewing fixings to enter profoundly into the skin; and the Australian organization Advanced Powder Technology has made Zinclear, a translucent zinc oxide sunblock made out of nanoparticles as little as the most diminutive known infections. "You have all the assurance however with no white lines on your nose and face," says Hugh Dawkins, head of an item advancement for the firm. 

In any case, are nanoparticles safe? This year researchers started to address transparently whether nanotech firms are careering toward an asbestoslike disaster. Nanoparticles are known to carry on in interesting and unusual ways incompletely in light of the fact that at the nanoscale, quantum material science can assume control, and the Newtonian material science of regular daily existence turns out to be less prevailing. "Particles of that size can go anyplace they please," says Pat Mooney, official executive of the innovation arrangement gather ETC, which discharged a report cautioning about nano toxins this spring. "They pass the whole safe framework. They can pass the blood-mind hindrance; they can go into the spinal line." 

As of late, NASA researcher Chiu-Wing Lam spritzed carbon nanotubes into the lungs of mice and found that they caused granulomas, knobs that are side effects of poisonous quality. At Rice University in Houston, specialists found that nanosize buckyballs—60 carbon molecules bound together in the state of a soccer ball—can attach to poisons, for example, naphthalene, abating the pace at which the contaminations are normally killed and incredibly extending the separation over which ecological poisons can spread. 

Albeit more than $1 billion was spent on nanotechnology look into this year, under 1 percent went to researching potential dangerous impacts. "We have to advance beyond everything, so dislike Freon or dry-cleaning chemicals," says Rice ecological designer Mason Tomson. 

Mobile phones Rival Alcohol as Driving Hazard 

You might be composed and have a sans hands telephone in your auto, however late examinations at the University of Utah propose that it isn't the dialing or the arm-waving that influences driving while at the same time chatting on a cell to telephone perilous. It's simply the yakking—or all the more correctly, the yakking to somebody who is absent. David Strayer, a Utah therapist, says, "You're driving execution while chatting on a PDA is debilitated at levels similar to, or more awful than, driving with a blood liquor level of .08," which is as far as possible in many states. 

Utilizing a driver-preparing test system, Strayer and a group of Utah specialists looked at the consideration levels and reaction times of 110 drivers in different circumstances. In thick movement, wireless clients were around 20 percent slower to react to sudden dangers than different drivers, and they were about twice as prone to backside a braking auto before them. "Mobile phone drivers are separating under 50 percent of the visual data that non-cell drivers are getting," says Strayer. "Looking and seeing are not one and the same." By differentiate, the analysts found that tuning in to the radio or chatting with travelers isn't as perilous. "At the point when a risky circumstance emerges, the driver and traveler put their discussion on stop," Strayer says. 

In the case of chatting with a traveler or somebody on a wireless, in any case, individuals are less ready to review the subtle elements of a discussion went ahead while driving, includes therapist Frank Drews, a coauthor of the investigation. "So it won't be useful for your financial wellbeing to talk about speculation techniques with your dealer while both of you is driving."
