“Early diagnosis guarantees therapeutic success in breast cancer”, claimed doctors Fernando Martínez Regueira and Luis Pina, specialists in de Mammary Pathology at the University Hospital.
Breast cancer is the most common tumour amongst the female population. In recent years its prevalence has increased considerably without the reasons thereof being very clear, although lifestyle changes such as first pregnancy taking place at a later age or the reduction in the period of breast-f
Following the announcement of the Venus Express launch delay due to particulate contamination found in the launcher fairing where the spacecraft was installed, ESA staff and industry teams have started an inspection of the spacecraft. This recovery ‘investigation procedure’ has so far revealed a spacecraft in good status.

Tension is mounting among students involved in the SSETI Programme as only two days now remain to the launch, by a Kosmos 3M rocket from Plesetsk Cosmodrome, of the student-built satellite – SSETI Express.
The last few weeks particularly have been an emotional roller coaster ride for the 15 teams of university students involved, particularly for the campaign team at Plesetsk in Russia, as they prepare SSETI Express for launch.
On 8 September the team arrived in Russia
Scientists have developed a technique which can be used to reveal the strength of bones, allowing doctors to more accurately estimate the risk of bone fracture.
According to research published online in the Journal of Bone Mineral Research, scientists have developed a laser imaging technique which can more fully assess the strength of bones, a technique the scientists hope can be used to predict the likelihood of young women developing osteoporosis in later life.

The sheer number and variety of security protocols for Internet applications under development makes it difficult to be sure that any one protocol is 100 per cent secure from attack. Now an automated tool can systematically validate these security-sensitive protocols and applications.
“The AVISPA software tool enables a security protocol designer to input the protocol and the language he/she wishes to use, then feeds back information on this protocol including any known bugs or
Roots are crucial for the development of strong, healthy crops. But until recently, exactly which genes are involved in the development of roots was still a mystery. Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to Ghent University have now analyzed a complete plant genome in order to identify the genes that are essential for the formation of capillary roots. For the first time, they are unraveling the genetic basis for the branching of the root system
UCSF scientists have illuminated a key step in a signaling pathway that helps orchestrate embryonic development. The finding, they say, could lead to insights into the development of stem cells, as well as birth defects and cancers, and thus fuel therapeutic strategies.
The study, reported in Nature (Oct. 13, 2005), focuses on the Hedgehog family of signaling molecules, which play a central role in directing development of the early embryo’s growth and spatial plan, as well as
Parents whose grown children have not yet flown the nest can only sympathize with the Western bluebird.
While female fledglings fly off on their own in late summer, their brothers typically hang around through the winter and into the next breeding season, living off the bounty of their parents’ larder.
As with humans, though, as the money runs low, the kids split, according to a new study by scientists at the University of California, Berkeley.

UCSD scientists have gained a better understanding of how repetitive stretching of endothelial cells that line arteries can make them healthy and resistant to vascular diseases.

Recent advances in wireless computing technology could improve deep-space missions like asteroid research and remote spacecraft operations by changing the way signals are sent from Earth. A new method designed to effectively deliver commands and instructions using hundreds of millions of tiny transmitters linked together could also free the giant satellite dishes currently used to send and receive the long-range information for other applications. A research paper describing the scheme for rela
The leech has recently confirmed its biomedical interest for scientists by showing that it contains an extensive list of new potential molecules that may become useful tools in the treatment of cardiovascular diseases. The details of this research appear in the October issue of Molecular and Cellular Proteomics, an American Society for Biochemistry and Molecular Biology journal.

In the first study of its kind, researchers at Saint Louis University have demonstrated that immunization with a new vaccine could potentially prevent more than a million cases of pertussis (whooping cough) each year in adolescents and adults.
Most children are protected from pertussis by a series of vaccines in early childhood. But the vaccine protection wanes after a decade or so, leaving adolescents and adults susceptible to the bacterial infection.

’Nature’ article says gold catalysts achieve cleaner, more efficient oxidation
The selective oxidation processes that are used to make compounds contained in agrochemicals, pharmaceuticals and other chemical products can be accomplished more cleanly and more efficiently with gold nanoparticle catalysts, researchers have reported in Nature magazine.
A team of 13 U.K. researchers and one U.S. researcher reported in the Oct. 20 issue of the British journal that the carbon-
A human red blood cell is a dimpled ballerina, ceaselessly spinning, tumbling, bending, and squeezing through openings narrower than its width to dispense life-giving oxygen to every corner of the body. In a paper published in the October issue of Annals of Biomedical Engineering, which was made available online on Oct. 21, a team of UCSD researchers describe a mathematical model that explains how a mesh-like protein skeleton gives a healthy human red blood cell both its rubbery ability to stret
Early nerve damage caused by repetitive strain injuries can trigger “sick worker” syndrome — characterized by malaise, fatigue and depression, and often mistaken for poor performance, according to a study by Ann Barr, Ph.D., and Mary Barbe, Ph.D., at Temple University’s College of Health Professions. The study, “Increase in inflammatory cytokines in median nerves in a rat model of repetitive motion injury,” is published this month in the Journal of Neuroimmunology.

An enzyme inside a bacterium that grows in the soil of potato fields can — in a split second — break down residues of a common powerful pesticide used for killing worms on potatoes, researchers have found.
That may be expensive for farmers but lucky for the environment because University of North Carolina at Chapel Hill scientists have now discovered that if that particular enzyme weren’t there, it would take 10,000 years for just half of the widely used pesticide to decompo
