Vegetarians who don’t cook their food have abnormally low bone mass, usually a sign of osteoporosis and increased fracture risk. But a research team at Washington University School of Medicine in St. Louis also found that raw food vegetarians have other biological markers indicating their bones, although light in weight, may be healthy.
The study, published in the March 28 issue of the Archives of Internal Medicine, was led by Luigi Fontana, M.D., Ph.D., research instructor i
Findings by USC researchers provide new potential options for prevention, therapy
Mutated BRCA1 genes cause ovarian cancer indirectly, by interfering with the biochemical signals one ovarian cell sends to another, according to a team of researchers led by scientists at the USC/Norris Comprehensive Cancer Center and the Keck School of Medicine of the University of Southern California. Their work is being published in the March 29 issue of the journal Current Biology.

Diffusion MRI shows 3 weeks into treatment if tumor is responding
A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient’s tumor will shrink, a new study shows.
Researchers at the University of Michigan Comprehensive Cancer Center developed the assessment, which they call a functional diffusion map. They used a magnetic resonance imaging scan that track
Like many other marine creatures, Aplysia, a common sea slug, enlists chemical defenses against its predators, but the mechanisms by which such chemical attacks actually work against their intended targets are not well understood by researchers. New work has now shown that such chemical defenses can involve modes of trickery that had not previously been appreciated as components of chemical defense.
When attacked by predatory spiny lobsters, sea slugs (also known as sea hares) rel
Hemoglobins, key components of our blood, are ancient proteins with well-known roles in oxygen transport and respiration in animals. Hemoglobins are also present in plants and bacteria, but until now the physiological role of plant hemoglobins has been unclear. A group of researchers reveal this week that one such mysterious plant hemoglobin serves to assist in the fixation of nitrogen in the root nodules of legumes through a process that is conceptually not unlike that undertaken by mammalian
In a paper in this month’s freely-available online global health journal PLoS Medicine, Roland Haubner and colleagues describe how a compound they have developed can be used together with highly sensitive positron emission tomography (PET) scanning to measure the amount of new blood vessel growth in some tumors.
New blood vessel growth – angiogenesis – is important for the growth of tumors; several drugs target angiogenesis specifically. The compound previously developed by
The Semantic Web lies at the heart of Tim Berners-Lee’s vision for the future of the Web, enabling a wide range of intelligent services. Thanks to the development of the infrastructure needed for the large-scale deployment of ontologies as the bedrock of the Semantic Web, that vision is much closer to reality.
Ontologies provide the lifeblood of the Semantic Web by defining shared and common domain theories, and allowing people and machines to communicate more effectively. They als
New dehydration method ensures inexpensiv granulated food of high quality
The Norwegian company Dtech AS – a spin-off of SINTEF and NTNU – is in the process of building a large factory on the basis of the results obtained by the three scientists.
The new plant will supply the international food industry with dried maize and dried peas – ingredients which will end up in dried soups and powdered casserole dishes all over the world.
High quality at low price
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, show part of the Medusa Fossae formation and adjacent areas at the highland-lowland boundary on Mars.
The HRSC obtained these images during orbit 917 with a resolution of approximately 13 metres per pixel. The scenes show an area located at about 5º South and 213º East.
The Medusa Fossae formation is an extensive unit of enigmatic origin found near the Martian ‘highlan
The Japanese theatre scholar, Professor Tatsuji Iwabuchi, and the Director of Japanese Studies at the University of Bonn, Professor Josef Kreiner, are this year’s winners of the Eugen and Ilse Seibold Prize in recognition of their contributions to the advancement of sciences and mutual understanding in both countries. This is the fifth time that the prize, which is worth €10,000, has been awarded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation).

The last outstanding hardware needed before arrival of the Automated Transfer Vehicle (ATV), the European-built ISS supply ship due for launch in 2006, has been installed outside the International Space Station (ISS) during a 4 1/2 hour Extra Vehicular Activity (EVA) on Monday 28 March.
The two ISS Expedition 10 crewmembers, Commander NASA astronaut Leroy Chiao and Flight Engineer Russian cosmonaut Salizhan Sharipov, who was the operational lead for the EVA, installed the last t
Data from ISO, the infrared observatory of the European Space Agency (ESA), have provided the first direct evidence that shock waves generated by galaxy collisions excite the gas from which new stars will form. The result also provides important clues on how the birth of the first stars was triggered and speeded up in the early Universe.
By observing our galaxy and others, scientists have long concluded that the explosion of massive stars like supernovae generates shock waves and
EUREKA project E! 2727 POLCORRIDOR has been selected as the ‘backbone’ trans-European freight transport corridor to explore interoperability in the EU Sixth Framework Programme (FP6) REORIENT project. REORIENT is assessing the process of transforming European railways from nationally fragmented into internationally integrated systems to encourage a move away from total dependence on road transport.
Started in 2002, the EUREKA project set out to deliver Europe’s most advanced tran
EUREKA project E! 3062 DAMAGE has developed a software tool to track and manage digital assets – the sound, illustrations, backgrounds, colour schemes and special effects – for production of a feature-length computer-generated imaging (CGI) animated film. While CGI animation provides popular and profitable entertainment, it has until recently been the multimillion dollar stronghold of the Hollywood giants.
The new software – and Valiant, the film on which it was tested and deve
More than 20 partners from all areas of the European car industry worked together in the EUREKA ITEA Cluster EAST-EEA project to develop a common software interface for electronic devices to be used in all cars from 2009. This will make the next generation of vehicles quicker to design and cheaper to bring to market, while maintaining high quality standards.
Electronics are being used increasingly to improve safety and comfort in all areas of the car – from engine, steering and br
The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects. The project of a team of the University of Vienna funded by the Austrian Science Fund (FWF) contributes to the Campus Vienna Biocenter maintaining a top-level position in the field of cell division research.
