BEIJING, Jan. 6 (Xinhua) -- Beijing will offer residents 20,000 rental bikes this year to ease the city's notorious traffic jams, according to authorities with the Beijing Municipal Commission of Development and Reform.Five hundred rental kiosks will be set up around the city to offer residents over 20,000 rental bikes, the commission said.Beijing has also proposed creating new bike lanes in some areas, including main streets, historical and cultural conservation areas and some major business districts, from 2011 to 2015, according to the commission.The capital city currently has about 5 million vehicles on its roads, leading to serious traffic congestion that frustrates the city's residents on a daily basis."A lack of bike lanes is the reason why I refuse to ride a bike. Bikes and vehicles are using the same lanes, and that frightens me and makes me feel unsafe," said Beijing resident Song Tao.People often park cars on the city's existing bike lanes, pushing cyclists onto the vehicles' lanes, said Song.To ease traffic congestion, Beijing has made various efforts to encourage people to opt for modes of public transportation.On Dec. 31, Beijing opened three new subway lines, bringing the number of subway lines in Beijing to 15, with a total length of 372 kilometers, said Beijing Metro Spokesman Jia Peng.Beijing will open four more subway lines in 2012, according to information released at a rail transit construction mobilization conference.Amid other measures to ease traffic in 2011, city authorities decided to allow only 240,000 vehicles to be registered annually, slashing the new car registrations by two-thirds from the 2010 level.Meanwhile, vehicles are banned from roads one day each week according to license plate numbers.

BEIJING, Jan. 10 (Xinhuanet) -- Conflicts among hundreds of scalpers raring to stock up on the new iPhone 4S are casting a shadow over the gadget's launch on the Chinese mainland on Friday.Over the weekend, scalpers from two groups bickered and shoved each other when standing in line to purchase iPhone 4 at Apple's Sanlitun store, said witnesses.Workers from two Apple stores in Beijing told China Daily the stores have not started online bookings for the iPhone 4S so far."More than 1,000 of us have gathered to buy all the available iPhone 4 this morning," said a scalper hawking the phone outside the Sanlitun store on Sunday."We'll come again on Friday for iPhone 4S. You'll have no hope of getting an iPhone 4 or 4S from the store, but only from us."The scalpers are asking 4,450 yuan (705 U.S. dollars) for an 8-gigabyte iPhone 4, and 5,450 yuan for a smuggled iPhone 4S. Apple sells an 8-gigabyte iPhone 4 on the mainland for 3,988 yuan.An Apple employee at the Sanlitun store who declined to give her name told China Daily on Monday that the store was aware the scalpers may be planning to besiege the iPhone 4S launch, and the store has prepared for that.Calls to the public relations office of Apple China went straight to voice mail.Police of the Sanlitun police station refused China Daily's interview request.An officer of the property management company of the Sanlitun Village shopping mall, where the store is located, said on Sunday they had not been informed about the weekend fracas outside of the Apple store.But on Monday afternoon, staff members of the company dispersed the scalpers by sealing off part of the store's entrance.Workers at the Sanlitun store and property management staff confirmed two groups of scalpers fought on Saturday afternoon and Sunday when jumping the line or stopping each other to pay to get an iPhone 4.Since October 2010, Apple has ceased direct sales of iPhone 4 at its retail outlets in Beijing and Shanghai and is only accepting online orders or reservations and schedules pick-up at stores to curb rampant scalping.But the registration system for reserve and pick-up has become "momentarily unavailable because of heavy traffic volume" in recent days, said Apple's website.A scalper in his 30s outside the Sanlitun store boasted they had "hacked" Apple's reservation page. He described himself an "unofficial salesman" of Apple.Defending the actions of scalpers that lead to consumers having to pay more, he said "it's not our fault but Apple's, because they put too few products in the mainland market."This is not the first time scalpers have targeted Apple products.Two men and two women suffered minor injuries outside the Sanlitun store during a clash between a worker and angry customers as Apple fans waited to buy iPhone 4 and the newly released iPad 2 in May 2011.According to reports, the incident started when a worker confronted an alleged scalper for jumping the line. This led to a verbal conflict in which the alleged scalper was thrown against the corner of an outside wall, causing injuries to his face and wrist

WASHINGTON, Nov. 9 (Xinhua) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea, the U.S. space agency announced Wednesday.The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists most because of its potential to cause a rapid rise in sea level. Satellite measurements have shown this area is losing ice and surrounding glaciers are thinning, raising the possibility the ice could flow rapidly out to sea.The multidisciplinary group of 13 scientists, led by Robert Bindschadler, emeritus glaciologist of NASA's Goddard Space Flight Center, will depart from the McMurdo Station in Antarctica in mid- December and spend six weeks on the ice shelf. During their stay, they will use a combination of traditional tools and sophisticated new oceanographic instruments to measure the shape of the cavity underneath the ice shelf and determine how streams of warm ocean water enter it, move toward the very bottom of the glacier and melt its underbelly."The project aims to determine the underlying causes behind why Pine Island Glacier has begun to flow more rapidly and discharge more ice into the ocean," said Scott Borg, director of NSF's Division of Antarctic Sciences, the group that coordinates all U.S. research in Antarctica. "This could have a significant impact on global sea-level rise over the coming century."

WASHINGTON, Dec. 20 (Xinhua) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system, the U.S. space agency announce Tuesday.The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun, according to NASA.The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1, 000 light-years away in the constellation Lyra.Kepler-20e orbits its parent star every 6.1 days and Kepler-20f every 19.6 days. These short orbital periods mean very hot, inhospitable worlds. Kepler-20f, at 800 degrees Fahrenheit, is similar to an average day on the planet Mercury. The surface temperature of Kepler-20e, at more than 1,400 degrees Fahrenheit, would melt glass."The primary goal of the Kepler mission is to find Earth-sized planets in the habitable zone," said Francois Fressin of the Harvard-Smithsonian Center for Astrophysics, lead author of a new study published in the journal Nature. "This discovery demonstrates for the first time that Earth-size planets exist around other stars, and that we are able to detect them."The Kepler-20 system includes three other planets that are larger than Earth but smaller than Neptune. Kepler-20b, the closest planet, Kepler-20c, the third planet, and Kepler-20d, the fifth planet, orbit their star every 3.7, 10.9 and 77.6 days. All five planets have orbits lying roughly within Mercury's orbit in our solar system. The host star belongs to the same G-type class as our sun, although it is slightly smaller and cooler.
