SAN FRANCISCO, June 22 (Xinhua) -- Apple Inc. has been awarded a long sought-after patent for touch screen functionality on portable devices, a set of exclusive rights expected to play into its current litigation against its counterparts in the mobile device market, U.S. media reported on Wednesday."A computer-implemented method, for use in conjunction with a portable multifunction device with a touch screen display, comprises displaying a portion of page content, including a frame displaying a portion of frame content and also including other content of the page, on the touch screen display," the U.S. Patent and Trademark Office patent abstract reads.Apple filed for the patent in December, 2007.Apple's patent essentially gives it ownership of the capacitive multitouch interface the company pioneered with its iPhone, on- line computer magazine PCMag quoted a source who has been involved in intellectual property litigation on similar matters as saying.The latest patent could produce a new round of lawsuits over the now-ubiquitous multitouch interfaces used in smartphones made by the likes of HTC, Samsung, Motorola, Research in Motion, Nokia, and others that run operating systems similar in nature to Apple's iOS, like Google's Android, said the patent expert.Apple has not immediately responded to request for comment on whether it will use the latest patent against competitors.Apple is currently involved in several patent-related battles with other companies. Nokia sued Apple in October 2009 for allegedly infringing patents the Finnish phone maker owns related to wireless handsets.Apple countersued Nokia in December 2009, accusing Nokia of infringing 13 Apple patents related to the iPhone. Nokia lodged a complaint later with the U.S. International Trade Commission, charging Apple of infringing seven Nokia patents "in virtually all of its mobile phones, portable music players and computers."Last Monday, Nokia said Apple had agreed to pay the Finnish company a license fee to settle all patent litigation between the two. Industry watchers said Nokia is likely to get around 608 million U.S. dollars from Apple.This April, Apple filed a lawsuit against Samsung, alleging that the Korean consumer electronics company has violated Apple's intellectual property in the design of its mobile devices, such as iPhone and iPad.Samsung later sued Apple separately in Asia, Europe and the United States, accusing Apple of infringing Samsung's 10 patents related to mobile phones.

SAN FRANCISCO, June 13 (Xinhua) -- Google on Monday confirmed that it had signed an agreement to buy Admeld, an on-line advertising optimization firm, in a deal seen as the Internet search giant's latest move to bolster its on-line display ad business.Admeld, launched in 2007 and headquartered in New York City, has developed a service that can help on-line publishers manage their ad space more efficiently and profitably.Admeld now has more than 500 customers worldwide, among them are FOX News, IDG TechNetwork, Discovery and The Weather Channel, according to information posted on its website."By combining Admeld's services, expertise and technology with Google's offerings, we're investing in what we hope will be an improved era of flexible ad management tools for major publishers, " Neal Mohan, Google's vice president of display advertising, said in a blog post announcing the deal."We believe that this investment will be an important step to help on-line publishers, and will further improve and grow the display advertising industry as a whole," Mohan noted.On-line display ads usually appear in forms that consist of images and may be interactive. According to the Interactive Advertising Bureau, a U.S. trade association, display-related on- line ad revenue in the United States totaled nearly 10 billion U.S. dollars in 2010.Financial terms of the deal were not disclosed by the two companies. TechCrunch, a technology blog site, has reported that Google paid around 400 million dollars.

WASHINGTON, July 20 (Xinhua) -- The loss of a protein that coats sperm may explain a significant proportion of infertility in men worldwide, according to a study by an international team of researchers led by University of California Davis.A paper describing the work was published Wednesday in the journal Science Translational Medicine. The research could open up new ways to screen and treat couples for infertility.The gene DEFB126 encodes a protein called Beta Defensin 126, which coats the surface of sperm and helps it penetrate cervical mucus in the female. A survey of samples from the U.S., Britain and China showed that as many as a quarter of men worldwide carry two copies of the defective gene.In the new study, researchers found that men with a muted DEFB126 lack Beta Defensin 126, making it much more difficult for sperm to swim through the mucus and eventually join with an egg.Examining 500 newly married Chinese couples, researchers found that the lack of Beta Defensin 126 in men with the DEFB126 mutation lowered fertility (even among men that did not display other deficiencies usually associated with infertility, like inadequate semen volume and low sperm motility). Wives of men with the Beta Defensin 126 variant were significantly less likely to become pregnant than were other couples, and 30 percent less likely to have a birth.This genetic variation in DEFB126 likely accounts for many unexplained cases of infertility, researchers say. They hope next to work with a major infertility program in the U.S. to further explore the role of the mutation.

WASHINGTON, June 2 (Xinhua) -- When humans see red, their reactions become both faster and more forceful, according to a new study published this week in the U.S. bimonthly journal Emotion.The findings may have applications for sporting and other activities in which a brief burst of strength and speed is needed, such as weightlifting. But the authors caution that the color energy boost is likely short-lived.The study measured the reactions of students in two experiments. In the first, 30 fourth-through-10th graders pinched and held open a metal clasp. Right before doing so, they read aloud their participant number written in either red or gray crayon. In the second experiment, 46 undergraduates squeezed a handgrip with their dominant hand as hard as possible when they read the word "squeeze" on a computer monitor. The word appeared on a red, blue, or gray background.In both scenarios, red significantly increased the force exerted, with participants in the red condition squeezing with greater maximum force than those in the gray or blue conditions. In the handgrip experiment, not only the amount of force, but also the immediacy of the reaction increased when red was present.The colors in the study were precisely equated in hue, brightness, and chroma (intensity) to insure that reactions were not attributable to these other qualities of color."Red enhances our physical reactions because it is seen as a danger cue," explains coauthor Andrew Elliot, professor of psychology at the University of Rochester and a lead researcher in the field of color psychology. "Humans flush when they are angry or preparing for attack," he explains. "People are acutely aware of such reddening in others and it's implications."But threat is a double-edged sword, argue Elliot and coauthor Henk Aarts, professor of psychology at Utrecht University, in the Netherlands. Along with mobilizing extra energy, "threat also evokes worry, task distraction, and self-preoccupation, all of which have been shown to tax mental resources," they write in the paper.In earlier color research, exposure to red has proven counterproductive for skilled motor and mental tasks: athletes competing against an opponent wearing red are more likely to lose and students exposed to red before a test perform worse.

LOS ANGELES, June 9 (Xinhua) -- The edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles approximately 100 million miles (160 million kilometers) wide, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.The finding was based on observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, said JPL in Pasadena, Los Angeles.While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles which are created when magnetic field lines reorganize, said JPL.The new model suggests the field lines are broken up into self- contained structures disconnected from the solar magnetic field, according to JPL."The sun's magnetic field extends all the way to the edge of the solar system," said astronomer Merav Opher of Boston University. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are, the folds of the skirt bunch up."Like Earth, our sun has a magnetic field with a north pole and a south pole. The field lines are stretched outward by the solar wind, a stream of charged particles emanating from the star that interacts with material expelled from others in our corner of the Milky Way galaxy.Understanding the structure of the sun's magnetic field will allow scientists to explain how galactic cosmic rays enter our solar system and help define how the star interacts with the rest of the galaxy.The Voyager spacecraft, more than nine billion miles (14 billion kilometers) away from Earth, are traveling in a boundary region. In that area, the solar wind and magnetic field are affected by material expelled from other stars in our corner of the Milky Way galaxy.Launched in 1977, the Voyager twin spacecraft have been on a 33- year journey. They are en route to reach the edge of interstellar space. JPL built the spacecraft and continues to operate them.
