“Full-field digital tomosynthesis is mammography–only better,” researchers say of a new technique that just might be the next generation of breast cancer screening. Two new studies on this technique illustrate that full-field digital tomosynthesis (TOMO) can not only increase the visibility of breast lesions but could likely dramatically reduce the number of patients being called back for a second mammogram because their first screening mammogram was unclear.
In the first study, researchers
Radiofrequency ablation — using heat to treat cancers – offers some lung cancer patients an alternative to extensive surgery, additional chemotherapy or radiation therapy, a new study shows.
Researchers at the Oncology Institute in Bari, Italy, treated 40 lung nodules found in 18 patients. Fourteen patients had lung metastases and four patients had non-small cell lung cancer that could not be surgically removed. All of the patients had initially undergone chemotherapy for their disease.
Self-organization is a growing interdisciplinary field of research about a phenomenon that can be observed in the Universe, in nature and in social contexts. Researchers seek explanations by using both experimental, often computer-based approaches and empirical, observational approaches. Mechanisms of self-organization are beginning to be identified and the theoretical foundation is under development. Research on self-organization tries to describe and explain forms, complex patterns and behaviours t
The Genetic and Microbiological research group at the Navarre Public University is working with the Agruset company from Rioja in the production of new commercial varieties of the fungus oreille de chardon mushroom (Pleurotus eryngii). The same group has developed 150 new varieties of the oyster mushroom (Pleurotus ostreatus), which enhances the productivity and quality of the varieties of this fungus which are currently being commercialised.

Today there are evermore intelligent objects, i.e., more devices that adapt to our needs. For example, there is intelligent clothing, intelligent computers, and intelligent household devices such as washing machines, music centres, lamps, and so on.
In fact, it is currently possible for a sensor at the entrance to a dwelling to recognise the voice or the odour of the owner and simultaneously open the door. It is also possible, on entering the house and depending on the mood or physical state
Scientists at the University of Sheffield have cast doubt on the validity of the controversial theory of biological cold fusion, the principle sometimes used to lend credence to the practice of selling silicon tablets to strengthen bones, on the assumption that the body will turn the silicon into calcium.
Biological cold fusion, also known as the ‘Kervran effect’, is the principle that living organisms can act as alchemists and turn one element into another. The French Scientist, Louis C. Ke
The explosive growth in mobile phones has been supported by a similar growth in the underlying networks of base stations used to connect calls. This has created headaches for network administrators charged with keeping an increasing numbers of base stations active at all times. Now a convenient new power and management cabinet allows administrators to manage the entire operation of base stations remotely, reducing time and costs and improving range.

A EUREKA funded project is making real progress in the fight against cancer of the large intestine. One of the three most common cancer types in western countries, cancer of the large intestine is also one of the hardest to diagnose. In 50 per cent of cases it is detected too late to be successfully treated with surgery. But EUREKA project GENEFEC has developed a new test which could save thousands of lives by detecting early signs of the disease.

W3C XML Protocol Working Group Requests Final Review of XML-based solution for Data Transport
The World Wide Web Consortium (W3C) today releases the SOAP Version 1.2 Proposed Recommendation, consisting of the SOAP 1.2 Messaging Framework; SOAP 1.2 Adjuncts, and a Primer. SOAP 1.2 is a lightweight protocol intended for exchanging structured information in a decentralized, distributed environment such as the Web. A W3C Proposed Recommendation is issued after review by the W3C Director,
For nine months before birth, infants soak in a watery, urine-filled environment. Just hours after birth, however, they have near-perfect skin. How is it that nature enables infants to develop ideal skin in such seemingly unsuitable surroundings?
A new study by researchers at the Skin Sciences Institute of Cincinnati Children’s Hospital Medical Center shows that the answer may be vernix — the white, cheesy substance that coats infants for weeks before they are born, then is wiped off and d
A research team led by The University of Texas M. D. Anderson Cancer Center has tested a novel “viral smart bomb” therapy that can completely eradicate brain tumors in mice, while leaving normal brain tissue alone.
The therapy, known as Delta-24-RGD, is thought to be the first treatment for malignant glioma, the deadliest form of brain cancer. It is a new-generation “replication-competent oncolytic” adenovirus therapy –– defined as a therapeutic virus that can spread, wavelike, throughout a
Exactly how a person’s eyes respond to low levels of light is even more crucial than doctors have thought in deciding who is and who isn’t a good candidate to have laser vision correction surgery, according to results announced today at the annual meeting of the Association for Research in Vision and Ophthalmology in Ft. Lauderdale. The findings should help doctors choose patients who are likely to fare well with the surgery, and to forego recommending treatment for others.

While it is well-established that roads can help spread invasive weeds, one new study shows that improved roads are worse than primitive ones, while another suggests that roadless areas act as refuges for native species against invasions.
Cheatgrass, knapweeds and other non-native plants have invaded nearly 125 million acres of the American West. Roads promote invasion because vehicles can transport non-native seeds into uninfested areas, and disturbed roadsides give weed seeds a place to g
Genetics may play a role in the success of anti-cancer therapy, according to researchers at the Research Institute of the McGill University Health Centre (MUHC) and the Lady Davis Institute for Medical Research of the Sir Mortimer B. Davis – Jewish General Hospital. Their study, published in today’s issue of Clinical Cancer Research, shows that some colorectal cancer patients with a particular gene mutation respond much better to therapy than those without this genetic change.

A new capsule that contains a microscopic camera and transmitter can create better pictures of the small bowel than standard x-ray procedures can, a new study shows. The capsule is easily swallowed by the patient, and there is no need for the patient to drink barium before the procedure.
The study, conducted by Sandor Joffe, MD, section head of abdominal imaging, and his colleagues at Beth Israel Medical Center in New York, found that wireless capsule endoscopy was better able than a small
