Early demo project identifies new brown dwarf

A new approach to finding undiscovered objects buried in immense astronomical databases has produced an early and unexpected payoff: a new instance of a hard-to-find type of star known as a brown dwarf.

Scientists working to create the National Virtual Observatory (NVO), an online portal for astronomical research unifying dozens of large astronomical databases, confirmed discovery of the new brown dwarf recently. The star emerge

Scottish company IceRobotics will develop a new generation of dairy farm robots, working in a way that is similar to an elephant’s trunk, that can milk cows without the presence of the farmer, thanks to an Invention & Innovation award of £98,000 from NESTA (the National Endowment for Science, Technology & the Arts), the organisation that invests in UK creativity and innovation.

While studying for his PhD, Dr Bruce Davies, a senior lecturer at Heriot-Watt University, came up with the id

New work by researchers in the Kimmel Cancer Center at Johns Hopkins may allow them to halt the smoking-induced cellular events that lead to 99 percent of all small cell lung cancers (SCLC). The research is reported in the March 5, 2003, issue of Nature.

The researchers found that a primitive cellular pathway, called Sonic Hedgehog (named for the cartoon character and spiky hairs it develops on fruit flies) stays turned on long after it should be turned off in some lung cancers.

New research into the origin of kidney stone formation published in the March 1 issue of the Journal of Clinical Investigation may well change the direction of the most basic level of research in that area.

The study, conducted at Indiana University School of Medicine, Clarian Health Partners and the University of Chicago, will dispel the current beliefs of where stone formation begins, said Andrew P. Evan, Ph.D., the article’s lead author. Dr. Evan, who is a professor of anatomy and c

Fruits and veggies grown organically show significantly higher levels of cancer-fighting antioxidants than conventionally grown foods, according to a new study of corn, strawberries and marionberries. The research suggests that pesticides and herbicides actually thwart the production of phenolics — chemicals that act as a plant’s natural defense and also happen to be good for our health. Fertilizers, however, seem to boost the levels of anti-cancer compounds.

The findings appear in the

Scientists with the U.S. Department of Energy’s Joint Genome Institute (JGI) and the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a powerful new technique for deciphering biological information encoded in the human genome. Called “phylogenetic shadowing,” this technique enables scientists to make meaningful comparisons between DNA sequences in the human genome and sequences in the genomes of apes, monkeys, and other non-human primates. With phylogenetic shadowing, scientists c
