Face recognition software is increasing important to areas ranging from surveiling to internet imagines searches. But research shows that face recognition systems do a poor job matching a face in photograph to a face seen in the real life. In fact, most people are pretty poor at tune, which is one reason why looking at mud shots can be unreliable. But researchers from the University of Glasgow have developed a new system that greatly improves the chances of matching a face with the photo from both computers and us. They announced their finding this week in the festival of science in York, England. You know how the occasional photo of you just doesn’t quite look like you, well the key to the new process is to use 10 or 11 different photos of a person and average those together to get a new image. Such averaging doesn't weight with other effects of individual shot that could be due to lighting or just the way how that to be holding your face, because your average face is more recognizable of you even though you are well above average.

British scientists have developed skis that wax themselves as you are skiing. The researchers who are working with ski manufactory try to self waxing skis in time for use in international competition early next year. Wax skis bottom provides lubrication effect that keeps snow from sticking and help skiers moving fast, but wax can wear off in the middle of run. The self skis includes seal reservoir that hold the lube. And attached to the ski under the ski foot, replace small blocks that usually there separate ski biding from ski. Tiny vail, the series of skis tubes continuously deliver new lube to the bottom of ski, and normal motion of skis legs enhance pump the fluid through system, No battery necessary. Test on the aisle shows skiers use the new skis cover the course one or two percent faster than conventional skis, which is huge in sports a hundredth or thousandth seconds separates winners from skis bums,

This is gonna come to a shut to anyone who spent an hour looking for a place to park in Manhattan. But we actually probably have a great of parking spaces in the US. And they have some unfortunate consequences. That's according to a study by researchers at Purdue University. They surveyed the total area devoted to parking in their mid-size mid-western county, turned out that parking spaces outnumber drivers by 3 to 1. And the total area devoted to parking spaces, places like big box stores and mega Churches was more than 2 square miles larger than a thousand football fields. One problem associated with the parking lots is water pollution. Oil, grease, settlement and heavy metals from car batteries collect on the lot service and then get washed away by rain fall into lakes and rivers. The parking lots lead to a thousand times the heavy metal run off than agriculture land of same size produces. And parking lots added the urban heat island effect whereby local temperatures might be by more than 5 degree Fahrenheit higher than in the surrounding areas.

If you ever get infection of cornea and you wear contact lens, save the lenses. They could help your doctor figure out what medication would be the best bet to cure what else you. Wearing contact is the associated with increase risk of microbe keratitis or corneal infection. Such infections that can sometimes lead to complication there might threat your sight. Doctors would take scraping form the corneal and then try to identify whatever organism they represent. But in the study reported in the September Issue of Archives Ophthalmology on the 34 percent of corneal scraping from contact lens wearing keratitis patients allowed the researchers to identify the manropes involved. But 70 percent of contact lens from the infected patients harbors microbes. The study include 49% patients with totally 50 infected eyes seen in a hospital in the Nearbo Australia said one of the study offers contact lens culture may give a clue requiring the identify of costive organism in situations in which the corneal scraping is cultural negative and may help to shoot the appropriate and microbe agent.

You are what you eat, so it has been said, well it turns out what we eat has also influenced who we are, down to the level of our genes. Researchers of the University California Santa Cruz have found that population of people who eat a high starch diet harbor extra copies of genes whose product breaks down starch. Okay, we all learned in high school biology that the genes come in pairs, one copy from mom, one from dad. In reality, things aren't always that simple, for some genes, we get multiple copies, such as the genes for Salisbury amylase the enzyme that kicks off the digestion of starch. On average we humans have half a dozen copy of that genes. I say "on average" because not everyone has six, one person could have two, and another could have ten. What the Santa Cruz scientists discovered is individuals from population that eat a lot starch, potatoes or corn or rice, scale to the high end of that copy number spectrum, and that quite a natural selection, more amylase probably confirmed the fitness banish to those who eating starchy foods. Chimps on the other hand, have only two copies of the amylase genes, may be because they are not bananas nor bread. |
