The NASA/ESA Hubble Space Telescope captured the dramatic effects of the collision early July 4 between a 370-kilogram projectile released by the Deep Impact spacecraft and comet 9P/Tempel 1.
The sequence of images (files enclosed to this release) shows the comet before and after the impact. The image at left shows the comet 10 minutes before the impact. The encounter occurred at 7:52 a.m. CEST
In the middle image, captured 15 minutes after the collision, Tempel 1 ap
A fundamentally new approach to computer identification of words was been suggested by Russian scientists. With its help, people will be able to give orders even to the most primitive cellular phones.
A sentient being recognizes without difficulty a familiar word regardless of the voice and intonation it is pronounced with. “Six” or “eight” remain six and eight for a person no matter how they are pronounced – in a loud voice or in a whisper, in an excited or a calm voice, by the
Gene pool of the Russian nation may be investigated using people’s surnames instead of genetic markers. This is being performed by Russian researchers supported by the Russian Foundation for the Humanities (RFH) and the Russian Foundation for Basic Research (RFBR).
Researchers use people’s surnames as a special class of genetic markers, with the help of which one can judge of internal diversity of human populations and relative connections between them. In Russia, specialists of
New forms of drugs for dysbacteriosis and other gastrointestinal disturbances are being developed by the Novosibirsk researchers with support of the International Science and Technology Center (ISTC).
A lot of Russians suffer from malfunction of gastrointestinal tract. The frequent reason for that is dysbacteriosis – disturbances of normal intestinal flora. To fight dysbacteriosis, physicians prescribe eubiotic drugs to patients, which contain bacteria necessary for digestion, f
One in fifty children and adolescents live with severely debilitating and recurrent pain but there is an “embarrassing” lack of data on the best ways to treat them, according to researchers.
As many as 15 per cent of children suffer from headaches, abdominal and musculoskeletal pain but two per cent of children have pain symptoms that can be severe enough to interrupt sleep, restrict physical activity and prevent them from attending school.
Studies have shown that childr
Women feel pain more than men despite the popular notion that the opposite is true, according to research.
Scientists investigating gender differences in pain have found that not only do women report more pain throughout the course of their lifetime, they also experience it in more bodily areas, more often and for longer duration when compared to men.
There also seem to be differences in how men and women think and feel about their pain. For example, anxiety may affec
The World Wide Web allows us to access masses of information, both textual and visual. Conducting a search for images by entering a few keywords into a search engine is simple, but such a search often results in hundreds and sometimes thousands of images being returned. Many of these images will be totally unrelated to the subject of the search as current image searching is largely based on words rather than image content.

The winner of the 2005 EMBO Science Writing Prize is Edwin Harold Rydberg of the Istituto di Ricerche di Biologia Molecolare (IRBM) P. Angeletti in Rome, Italy. The theme of the competition was ‘genes and behaviour’ and the winning entry deals with an area widely studied in behavioural genetics – the commonly misunderstood condition of schizophrenia. Rydberg’s elegant narrative reveals the personal impact of this distressing condition and the difference understanding the biology behind a conditi
Establishing live, interactive links between pupils on field trips and those in the classroom is a set of tools that frees teachers from the challenge of engaging all pupils on external field trips.
Organising field trips may sometimes be difficult because the venue limits the total number of visitors or parents may simply be unable to afford the additional costs involved. Therefore the IST programme-funded RAFT project set out to demonstrate the educational benefits of externa
The Gaiker Technology Centre, member of the IK4 technological platform, has carried out in collaboration with ANTEC, S.A. and TENNECO a technological research project to manufacture a new range of ecological shock absorbers able to provide major security level and comfort to drivers and users of vehicles and to improve their competitiveness from traditional products.
The importance of this project is that it increases substantially the security of vehicles, by improving damping through th
Actelion Ltd (SWX: ATLN) announced today that a study published in the July edition of the Journal of Neurosurgery suggests that clazosentan can reduce the number and severity of cases of vasospasm following aneurysmal subarachnoid haemorrhage (SAH).1
Vasospasm occurs 5-14 days following SAH and leads to strokes and neurological deficits that cause significant disability to patients and is a major cause of death. As many as 70% of people who have aneurysmal SAH may have arteria
Research led by biologists at the University of California, Berkeley, has found that damage to a cell’s DNA sets off a chain reaction that leads to the increased expression of a marker recognized by the body’s immune system.
The new findings, to be published July 3 in an advanced online issue of Nature, shed light on a long-standing question of how the natural killer (NK) cells – which are able to attack tumors – can differentiate cells that are cancerous from those th
Analysis of the brain of a patient suffering from Parkinson’s disease has shown for the first time that an experimental treatment can reverse the loss of nerve fibres.
Analysis of the brain of a patient suffering from Parkinson’s Disease has shown that the experimental treatment he received caused regrowth of the nerve fibres that are lost in this disease. The findings are reported in the July issue of Nature Medicine.
This is the first time that any treatment has be
Rockefeller scientists show that microRNAs play an essential role in the development of the fruit fly
In a story reminiscent of David and Goliath, new research from Rockefeller University shows that sometimes the smallest molecules can be the most powerful. In the July 1 issue of Cell, Ulrike Gaul, Ph.D., and colleagues report that microRNAs serve very important, and very specific, functions during the early development of the fruit fly.
First discovered a few years ago
Identification of soils that inhibit a tiny soybean-destroying organism is an important tool in reducing yield losses, according to a Purdue University plant pathologist.
Soybean cyst nematodes cause between $800 million and $1 billion annually in crop losses in the United States, according the American Phytopathological Society. However, techniques are available to find soils that specifically suppress these microscopic roundworms, said Andreas Westphal, assistant professor of p
Your IQ and extracurricular interests as a teenager may forecast your memory and thinking abilities decades later.
A new study by researchers at the University Memory and Aging Center, affiliated with Case Western Reserve University (Case) and University Hospitals of Cleveland (UHC), found that persons who were more active in high school and who had higher IQ scores, were less likely to have mild memory and thinking problems and dementia as older adults. Their results are published
