Washington, Oct 21 : US Democratic presidential nominee Barack Obama is expected to suspend his campaign trail for one full day this weekend to see his seriously ailing grandmother, who raised him as a child along with his mother and grandfather.

Senior advisor in Obama’s campaign programme, Robert Gibbs said she was released from hospital late last week but had not improved.

Washington, Oct 21 : A new study has determined that reducing the number of deer in forests and parks may unexpectedly reduce the number of snakes, salamanders and insects in that area, thus suggesting that these creatures thrive in areas with higher deer populations.

The study was carried out by researchers at Ohio State University and National Park Service, who found that higher deer activity is modifying forest ecosystems in unexpected ways.

Out of several species of snakes, salamanders, and invertebrates studied, a greater diversity of animals were found in areas with deer populations than were in areas with no deer activity.

Bodhgaya, Oct 21 : Monks in Bodh Gaya have staged a demonstration against barricading of the sacred Bodhi tree by the Bodhgaya Temple Management Committee (BTMC).

Monks alleged that a scientist of Forest Research Institute (FRI) had submitted to BTMC a report stating that offering of prayers by the monks just below the sacred tree would stop intake of oxygen to its roots, drying down it in due course of time.

They marched down towards the Bodhgaya management office, raising slogans for removal of the barricades around the sacred tree.

Washington, Oct 21 : Using a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe, which suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous burst of star formation.

The astronomers used the National Science Foundation’s Very Large Array (VLA) radio telescope to look at a galaxy more than 12 billion light-years from Earth, seen as it was when the Universe was only about 15 percent of its current age.

Between this galaxy and Earth lies another distant galaxy, so perfectly aligned along the line of sight that its gravity bends the light and radio waves from the farther object into a circle, or “Einstein Ring.”

New York, Oct. 21 : Democratic presidential candidate Barack Obama is outspending Republican rival John McCain in TV ads by nearly four to one, according to the independent Campaign Media Analysis Group.

The New York Daily News quoted Sarah Niebler, deputy director of the Wisconsin Advertising Project, as saying that Obama would smash President Bush''s 2004 record of 188 million dollars in TV spending any day now.

Last week alone, Obama broadcast some 50,000 30-second spots on national, local and cable TV channels, according to the Campaign Media Analysis Group.
