Avian Flu Research Sheds Light on Swine Flu Outbreak
A recent study by University of Maryland researchers examines the mechanisms underlying transmission of combined avian-human viruses and illustrates how virus outbreaks like that of the current swine flu come about. view more (2009-04-30)
A crucial role for TGFbeta signaling in congenital eye disorders
The lens in the developing eye acts as a TGFbeta signaling center that controls differentiation, survival and formation of multiple eye structures deriving from the neural crest. view more (2005-12-14)
2-million-year-old evidence shows tool-making hominins inhabited grassland environments
In an article published in the open-access, peer-reviewed journal PLoS ONE on October 21, 2009, Dr Thomas Plummer of Queens College at the City University of New York, Dr Richard Potts of the Smithsonian Institution National Museum of Natural History and colleagues report the oldest archeological evidence of early human activities in a grassland... view more...

Two new lakes found beneath Antarctic ice sheet
The Earth Institute at Columbia University-Lying beneath more than two miles of Antarctic ice, Lake Vostok may be the best-known and largest subglacial lake in the world, but it is not alone down there. view more (2006-01-26)
Dangerous printer particles identified
The identity and origin of tiny, potentially hazardous particles emitted from common laser printers have been revealed by a new study at Queensland University of Technology. view more (2009-02-11)
Human Genetic Research: House Of Lords Debate
As the second main item of business on Tuesday 15 January (starting between about 5pm and 6pm), the House of Lords is to debate the Science and Technology Committee's recent report Human Genetic Databases: challenges and opportunities together with the Government's response. The debate will be opened by Lord Oxburgh (Ron Oxburgh, the former Rector... view more... (2002-01-09)
Lung cancer suppresses miR-200 to invade and spread
Primary lung cancer shifts to metastatic disease by suppressing a family of small molecules that normally locks the tumor in a noninvasive state, researchers at The University of Texas M. D. Anderson Cancer Center report in the Sept. 15 edition of Genes and Development. view more (2009-09-15)
ESA scientist discovers a way to shortlist stars that might have planets
Markus Landgraf of the European Space Agency and colleagues (*) have found the first direct evidence that a bright disc of dust surrounds our Solar System, starting beyond the orbit of Saturn. Remarkably, their discovery gives astronomers a way to determine which other stars in the Galaxy are most likely to harbour planets and allows mission... view more... (2002-02-15)
Oxford Biomedica Obtains Further Fundamental Patent For Lentiviral Gene Therapy Technology
Oxford BioMedica plc announced today that it has received allowance from the US Patent Office for a further patent covering its proprietary LentiVector technology. This additional patent compliments the US patent 6,312,682 issued in November 2001 and both include broad composition of matter claims and methods of production claims for lentiviral... view more...

ESRF helps reveal the origin of the Solar System
Particles returned to Earth last January by the Stardust spacecraft from comet Wild 2 are yielding precious information about the origin of the solar system, thanks to the brilliant X-rays produced at several of the world's synchrotron facilities, including the ESRF. view more (2006-12-18)
Sensorial evaluation of the freshness of fish
AZTI has drawn up some 40 tables for freshness specific for the most important commercial species in southern Europe, including fish and shellfish. The sensorial method, known as QIM (Quality Index Method) and introduced into Europe some years ago, is being applied to a greater number of species, including some in the frozen state. Concretely, for... view more... (2005-04-18)
Rickettsia felis, a cat-flea-borne pathogen, sheds light on Rickettsial evolution
VBI researchers in collaboration with scientists from the University of Maryland School of Medicine have created a new classification system for rickettsia bacteria that may assist researchers in the way they approach the development of diagnostics and vaccines for the virulent rickettsial pathogens. view more (2007-03-07)
Fatty acid catabolism higher due to polyphenol intake
Polyphenols, dietary substances from vegetables, fruits and green tea, bring about a change in the energy metabolism. Dutch researcher Vincent de Boer has discovered that polyphenols increase the fatty acid breakdown in rats and influence the glucose use in fat cells. view more (2007-05-15)
Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin of climatic gradients of diversity. The... view more... (2005-01-11)
Toxic Bile Damages the Liver
Researchers at the Heidelberg University Hospital have discovered a new genetic disease that can lead to severe liver damage. Because a protective component of the bile is missing, the liver cells are exposed to the toxic components of the bile, resulting in cirrhosis of liver, a transformation of liver cells into connective tissue with a gradual... view more...

A new control mechanism for genetic code translation discovered in bacteria
Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life. view more (2008-02-15)
Variants Of SARS Virus Gives Clues To Origin Of Infection
A genetic study of the SARS virus fast-tracked for publication on THE LANCET's website-www.thelancet.com-gives an insight into the molecular behaviour of the novel coronavirus responsible for SARS. Comparison of a virus isolate from Singapore with isolates from other countries where SARS has struck suggests that there are main components of the... view more... (2003-05-08)
New study shows health benefits of probiotic could extend to the entire body
Data from a recent study demonstrate the anti-inflammatory and pathogen protection benefits of Bifidobacterium infantis 35624 a probiotic bacterial strain of human origin. view more (2008-08-25)
New type of flying reptile discovered
An international group of researchers from the University of Leicester (UK), and the Geological Institute, Beijing (China) have identified a new type of flying reptile - providing the first clear evidence of an unusual and controversial type of evolution. view more (2009-10-14)
New 'Knock-Out' Gene Model Provides Molecular Clues to Breast Cancer
New insights into the role of estrogen receptor in mammary gland development may help scientists better understand the molecular origin of breast cancer, according to new research from the University of Cincinnati (UC). view more (2007-09-06)
