MIGRATING DOCTORS (pp 177, 245)
The increasing divide between less-developed and more-developed countries in the quality of health care is well recognised. In this week's LANCET, Peter E Bundred and colleagues, from Liverpool and Canada describe how the prospects of a better standard of life are attracting large numbers of doctors to more-developed countries and away from... view more...

Innovative movies show real-time immune-cell activity within tumors
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. view more (2006-11-21)
Researchers identify mechanism used by gene to promote metastasis in human cancer cells
Virginia Commonwealth University Institute of Molecular Medicine and VCU Massey Cancer Center researchers have discovered how a gene, melanoma differentiation associated gene-9/syntenin (mda-9/syntenin), interacts with an important signaling protein to promote metastasis in human melanoma cells, a discovery that could one day lead to the... view more...

Urbanization favors sedentary males
Urbanization changes landscapes and local environments, which can alter the life histories and traits of the creatures living in and around these areas. view more (2007-05-02)
UCSD team creates model for genetic brain syndrome
Researchers at the University of California, San Diego (UCSD) School of Medicine took a step closer to understanding the basis of a severe epilepsy and mental retardation syndrome. view more (2006-01-05)
Bent tectonics
More than 80 undersea volcanoes and a multitude of islands are dotted along the Hawaii-Emperor seamount chain like pearls on a necklace. A sharp bend in the middle is the only blemish. view more (2009-04-03)
'No Competitive Edge' from Internet Banking - UU Research
Research conducted by University of Ulster financial services researcher Mark Durkin into the uptake of Internet-based banking has found that banks are embracing the innovation in order not to be put at a competitive disadvantage - rather than for any sustainable competitive advantage Internet banking might provide in its own right. The research... view more... (2002-10-02)
Key factor in brain development revealed, offers insight into disorder
In the earliest days of brain development, the brain's first cells - neuroepithelial stem cells -- divide continuously, producing a population of cells that eventually evolves into the various cells of the fully formed brain. view more (2008-03-27)
Post-pregnancy events promote breast tumor metastasis
Changes in the tissue environment of the breast that occur after pregnancy promote the metastasis of breast tumor cells. view more (2006-02-03)
New research proves single origin of humans in Africa
New research published in the journal Nature (19 July) has proved the single origin of humans theory by combining studies of global genetic variations in humans with skull measurements across the world. view more (2007-07-19)
Flu virus trots globe during off season
The influenza A virus does not lie dormant during summer but migrates globally and mixes with other viral strains before returning to the Northern Hemisphere as a genetically different virus, according to biologists who say the finding settles a key debate on what the virus does during the summer off season when it is not infecting people. view more (2007-09-21)
New origin found for a critical immune response
An immune system response that is critical to the first stages of fighting off viruses and harmful bacteria comes from an entirely different direction than most scientists had thought, according to a finding by researchers at the Duke University Medical Center. view more (2009-03-02)
Report highlights surprising resilience of Britain's seaside towns
Research published today (Thursday 19 June) challenges accepted stereotypes of seaside town economies. A common assumption has been that the rising popularity of foreign holidays has led to economic decline in Britain's seaside towns. A new report, released today (Thursday) at the British Resorts Association annual conference, paints a more... view more... (2003-06-16)
Uranium 'pearls' before slime
Since the discovery a little more than a decade ago of bacteria that chemically modify and neutralize toxic metals without apparent harm to themselves, scientists have wondered how on earth these microbes do it. view more (2006-08-08)
Are wolves the pronghorn's best friend?
As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope. view more (2008-03-04)
Global signaling study suggests cancer link to protein promiscuity
When found at abnormally high concentrations, two proteins implicated in many human cancers have the potential to spur indiscriminate biochemical signaling inside cells. view more (2005-11-17)
Sophisticated monitoring array to address mystery of uranium plume
Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. view more (2008-09-18)
Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of biomedical engineering at Emory University and the Georgia... view more...

How actin networks are actin'
Dynamic networks of growing actin filaments are critical for many cellular processes, including cell migration, intracellular transport, and the recovery of proteins from the cell surface. view more (2008-01-03)
Stem cells as cancer therapy
It is widely hoped that neural stem cells will eventually be useful for replacing nerves damaged by degenerative diseases like Alzheimer disease and multiple sclerosis. But there may also be another use for such stem cells-delivering anti-cancer drugs to cancer cells. view more (2006-12-26)
