Top seed and defending champion Agnieszka Radwanska of Poland was defeated by American qualifier Bethanie Mattek-Sands 7-5, 6-3 in the second round of the Sydney International, a key warm-up tournament for the Australian Open.

Mattek-Sands, who is back on tour after a four-month layoff because of a right knee injury, lost in the first round in Brisbane last week and had to win three matches just to qualify for the main draw in Sydney.

The Cleveland Cavaliers traded Andrew Bynum in time — and got an All-Star in return.

Former U.S. Homeland Security Secretary Janet Napolitano is ready for the focus of the Sochi Olympics to shift from security concerns and terrorism threats to all the athletes who will be competing.

Yet Napolitano, who is leading the U.S. delegation at the games, fully understands the daunting task of organizing an event of this magnitude — especially in the wake of two suicide bombings last week in the Russian city of Volgograd, 400 miles (640 km) from Sochi.

In Iran, free condoms and government-backed vasectomies are out, replaced by sermons praising larger families and discussions of even offering gold coins to the families of newborns.

Having successfully curbed birth rates for two decades, Iran now is promoting a baby boom to help make up for its graying population. But experts say it is difficult to encourage Iranians to have more children in a mismanaged economy hit by Western sanctions and 36 percent inflation.

Huawei, China's largest cellphone manufacturer, is releasing a phone that can be thought of as the inflight refueling system of the mobile world: it can be used to recharge other phones.

The Ascend Mate2 has a 6.1-inch (15.5-centimeter) screen, making it more than twice as big as an iPhone 5. It's almost the size of a tablet, giving rise to the half-joking term "phablet." It's the successor to a phone of the same size launched last year.

LG will bring the software that once powered Palm's smartphones to the majority of its Internet-connected TVs this year.

The South Korean firm unveiled webOS-based smart TVs at a trade fair Monday in Las Vegas, less than a year after it bought the operating system for smartphones and tablet computers from Hewlett-Packard Co.

Samsung Electronics Co., the world's largest maker of TVs, said Monday that it is tackling the problem of getting ultra-high-definition content to its new TV sets by teaming up with the Internet streaming services of Comcast, Netflix and Amazon.

Like other TV makers, the South Korean electronics company is betting that a quadrupling of the resolution of TV sets will get consumers interested in upgrading their existing, high-definition sets. The problem is that cable TV services and Blu-ray discs don't support the bump in resolution, leaving the ultra-sharp sets without ultra-sharp content.

Intel says all its processors this year will be made from minerals that don't hail from mines held by armed groups in the Democratic Republic of the Congo.

It's the first major U.S. technology company to make such a claim. It's the fruit of four years of work by the company to determine the sources of four crucial metals widely used in electronics manufacturing: tantalum, tungsten, tin and gold.

German Chancellor Angela Merkel has suffered a pelvis injury during a skiing holiday in Switzerland, putting her on the sidelines for the next three weeks.
