Washington, Mar 24: Children and siblings of people with venous thrombosis, or blood clots in the veins, may be more than twice as likely to develop the condition than those without a family history, say Dutch researchers.

Venous thrombosis typically begins in leg veins, although the clot may subsequently break off and travel to the lungs.

"Because universal screening is not cost-effective, research efforts are focused on selection criteria that may be used to increase the chance of finding a genetic risk factor," the authors write.

Washington, March 24 : Redoubt Volcano in Alaska, has roared into activity overnight with a series of eruptions that blew ash as high as 9.5 miles (15 kilometers) into the sky, with scientists saying that more such explosions are due.

According to a report in National Geographic News, the Redoubt Volcano eruption has already sparked earthquake swarms and mudflows, and more are expected-along with perhaps a new lava dome.

Hancock (New York), Mar. 24 : If you didn''t know where to look, you''d probably never find Islamberg, a private Muslim community in the woods of the western Catskills, 150 miles northwest of New York City.

This town, sitting on a quiet dirt road past a gate marked with No Trespassing signs, is home to an estimated 100 residents.

Sheikh Syed Mubarik Ali Shah Gilani, a Pakistani cleric who purchased a 70-acre plot and invited followers, founded Islamberg in 1980. It consists mostly Muslim converts.

Washington, March 24 : A new discovery of a jumble of at least three young Triceratops in the badlands of the north-central US has suggested that the three-horned dinosaurs were social animals, and may have exhibited unique gregarious groupings of juveniles.

Until now, all known Triceratops (over 50 in total) fossils have indicated that the prehistoric animals were solitary individuals.

Washington, Mar 24 : Ever since Reese Witherspoon has voiced a character in animated movie `Monsters vs. Aliens', she has got a "cool" status in the eyes of her kids, who no longer think of her as a "gigantic dork."

Although the `Walk The Line' star has won critical accolade and an Oscar for her previous work, she hasn't really impressed her kids, Ava and Deacon.

But after she lent her voice to a giant woman in the family film, she has suddenly become "cool" at home.

Washington, mar 24 : Seeing a huge restaurant menu usually makes us choose an old favourite instead of trying something new. Now, scientists have claimed that, when overloaded with information, other animals too display such behaviour.

Researchers from University of Leeds used computer modelling to examine the evolution of specialisation, and have shed light on why some animal species have evolved to eat one particular type of food.
