U.S. software giant Microsoft and Internet company Yahoo have agreed to a partnership both companies hope will change how Internet users search the World Wide Web. The agreement gives Microsoft access to the Internet's second largest search engine. But industry experts say the deal is part of a larger strategy to challenge the dominance of the Internet's biggest search engine — Google.

Every time a user goes online, invisible search engines scan billions of bits of information in a process that will ultimately help them decide which Web site to click on. These search engines are patented, complex algorithms worth potentially tens-of-billions of dollars. And, Microsoft, with its search engine, has made it clear it wants a bigger share.

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results — literally shrinking the lab down to the size of a thumbnail. Toward that end, UCLA researchers have developed technology to perform more than a thousand chemical reactions at once on a stamp-size, PC-controlled microchip, which could accelerate the identification of potential drug candidates for treating diseases like cancer.

Russia has banned the importation of kangaroo meat from Australia. Producers fear the decision will decimate their industry. Russia was the main market for the Australian kangaroo trade, accounting for about 70% of international demand.

Russia is worried about the bacterial contamination of kangaroo meat. Officials in Moscow have said that several recent consignments have been tainted with E-coli bacteria and will not allow further shipments into the country.

The import ban is a major blow to Australian producers. Russia was their biggest international customer and hundreds of jobs are now at risk. Already a handful of meat processing plants have closed down.

An unmanned Russian spacecraft has docked successfully with the International Space Station delivering cargo and supplies for its crew.

A spokesman for Russian Mission Control Valery Lyndin says the Progress M-67 craft reached the docking module Wednesday. He said the space station crew guided the freighter to the station's docking port using manual controls.

The craft lifted off Friday from the Baikonur space center in Kazakhstan, carrying two-and-a-half tons of supplies including food, water, fuel and various equipment to the station.

The space station's permanent crew doubled to six in May. It now includes two Russians, two Americans, a Canadian and a Belgian.

At two recent congressional hearings, U.S. diplomats, defense and military officials outlined how the Obama administration intends to go about "resetting" the U.S. relationship with Russia. Lawmakers on the House of Representatives Foreign Affairs, and Armed Services committees asked some tough questions about key aspects of the U.S-Russian relationship.

Questions about where the U.S.-Russia relationship is going are many, ranging from arms control, missile defense and nonproliferation and Iran's nuclear program, to cooperation in counter-terrorism and U.S. concerns about human rights and media freedom in Russia.

Among questions: How can the U.S. work with Russia to persuade Iran to end its uranium enrichment program? How to deal with Moscow's concerns about NATO enlargement? How to maintain support for the Republic of Georgia and Ukraine? What about human rights issues and media suppression in Russia?
