New study may have implications for millions in search of the elusive “good night’s sleep”

In movies and novels alike, much is made of the stage of sleep known as rapid eye movement (REM), since this is the phase of slumber in which dreams (good, bad, exotic) occur. Among the medical community, there is an increased appreciation for what is called “slow-wave” sleep, (also known as deep or delta-wave sleep), because this fourth stage of sleep can be difficult to attain. If one is aw

To study the genetic components of disease, researchers rely on mice or other research models in which particular genes are silenced, or turned off. In recent years, researchers discovered that they can selectively silence genes using small pieces of RNA called siRNA (short interfering RNA).

Unfortunately, sorting out which siRNA sequences block expression of which genes has proven to be truly daunting. Researchers at Whitehead Institute, however, recently released for public use a new comp

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
