Washington, Oct 22 : Radiologists can now use three-dimensional (3-D) power Doppler ultrasound to differentiate between malignant and benign breast cancer cells, according to a new study.

Usually, malignant breast masses have increased blood flow compared to normal tissue or benign masses.

The study has found that using 3-D power Doppler ultrasound can make it is possible to detect vessels with higher flow speeds, which likely indicate cancer.

"Using 3-D scans promises greater accuracy due to more consistent sampling over the entire tumor," said lead author, Gerald L. LeCarpentier, Ph. D., assistant professor in the Department of Radiology at University of Michigan in Ann Arbor.

Washington, Oct. 22 : A political scientist has predicted significant gains for the Democratic Party in the 2008 congressional elections—including 11 seats in the U. S. House of Representatives and three seats in the U. S. Senate.

Carl Klarner of Indiana State University published his forecast in the October 2008 issue of PS: Political Science and Politics, a journal of the American Political Science Association (APSA).

The House and Senate forecasts were made in late July 2008, and Klarner’s model focuses on the percent of the major-party vote that the Democratic candidate received in a state or district.

Washington, Oct 22 : A research team, involving an Indian origin scientist, has developed a new self-assembling hydrogel drug delivery system that can ill not only deliver clinically approved drugs in high concentrations, but also do away with any toxic residue in the process.

Developed by scientists from Harvard-MIT Division of Health Science and Technology (HST) at Brigham and Women''s Hospital, the system is biocompatible, efficient at drug release, and is also easy to tailor.

The structures will do way with carriers for the drug or generating toxic components—a problem encountered with hydrogel systems until now.

Kampala  - Most of the estimated 30,000 children abducted by Ugandan rebels of the Lord's Resistance Army (LRA) during its two- decade-long war with the government were sold to fight in Sudan's restive Darfur province, Uganda's Daily Monitor reported Wednesday.

The children were first forced by the LRA to fight and commit atrocities. Afterward, they were sold to various rebel armies in Darfur to fight or to serve as sex slaves, the newspaper quoted Stephen Kagoda, permanent secretary in the Ministry for Internal Affairs, as telling parliament.

Riga/Vilnius - The chairman of the US joint chiefs of staff Admiral Michael G Mullen was in the Lithuanian capital, Vilnius, Wednesday at the end of a brief but highly symbolic visit.

He had talks with President Valdas Adamkus less than a day after his eight-car motorcade cut a swathe through Riga's evening rush hour to drop him at Riga castle to see Latvian president Valdis Zatlers.

Mullen's Baltic detour came immediately after the conclusion of talks in Helsinki where top military leaders from the United States and Russia met Tuesday for the first time since this summer's war between Russia and Georgia.
