Hubble’s deepest view ever of the Universe unveils earliest galaxies

Astronomers today unveiled the deepest portrait of the visible Universe ever achieved by humankind. Called the Hubble Ultra Deep Field (HUDF), the million-second-long exposure reveals the first galaxies to emerge from the so-called ’dark ages’, the time shortly after the ’Big Bang’ when the first stars reheated the cold, dark Universe. The new image should offer unprecedented insights into what types of objects reheated the Universe long ago.

This historic new view is actually made up by t

High-tech flax and hemp — from car panels to lightweight concrete

While textile flax produced in France is exported all over the world for the production of high-quality linen clothes and sheets, these natural fibres are now being re-discovered by French manufacturers and put to unexpected and exciting uses.

Increasingly, flax is being used by automotive equipment manufacturers as a source of raw material that is environmentally friendly and less dangerous — in the event of a vehicle crashing — when used for interior panels in cars. Hemp fibres are also e

Tai Chi has physical, psychological benefits

A review of previously published studies suggests that among patients with chronic health conditions, Tai Chi appears to have beneficial effects on balance, flexibility, and cardiovascular health, according to a review article in the March 8 issue of The Archives of Internal Medicine, one of the JAMA/Archives journals.

According to the article, Tai Chi is a traditional Chinese martial art that has been practiced in China for centuries. Tai Chi combines deep breathing with relaxation and po

Baker’s yeast rises from genome duplication

In work that may lead to better understanding of genetic diseases, researchers at the Broad Institute of MIT and Harvard show that baker’s yeast was created hundreds of millions of years ago when its ancestor temporarily became a kind of super-organism with twice the usual number of chromosomes and an increased potential to evolve.

The study is by postdoctoral fellow and lead author Manolis Kellis of the Broad (rhymes with “code”) Institute; Eric S. Lander, Broad director; and Bruce W.

Search for macular degeneration genes narrows

Scientists zero in on five chromosome regions

Scientists at the University of Michigan Kellogg Eye Center, working with colleagues in the U-M School of Public Health, have significantly narrowed the range of chromosomal locations where they expect to find genes associated with age-related macular degeneration (AMD).

In a paper published in the March issue of American Journal of Human Genetics, Kellogg scientist Anand Swaroop, Ph.D., and his team of researchers have confirmed

New Breast Pap Smear Detects Early Cellular Changes; May Prevent Onset of Breast Cancer

Long before a woman feels an ominous lump in her breast, Victoria Seewaldt, M.D., can test her for subtle signs that breast cancer may be brewing in a few errant cells amidst thousands of healthy ones. Never before has such a possibility existed, and Seewaldt is brimming with excitement.

“This is potentially the ’breast pap smear’ that we never had before,” said Seewaldt, a scientist and breast oncologist at the Duke Comprehensive Cancer Center. “Just as we do with a cervical pap
