A new study from Minnesota finds the incidence of nonmelanoma skin cancer increasing among men and women under the age of 40, according to an article in the August 10 issue of JAMA.
The overall incidence of nonmelanoma skin cancer, consisting of squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), is increasing, according to background information in the article. This increasing incidence is most likely due to a combination of factors, including increased exposure to UV
Researchers report on the state of Iraq’s Mesopotamian marshes
While much of the world has focused on the war in Iraq, a group of wetland ecologists has been busy collecting data on the Mesopotamian marshes of southern Iraq. Formerly the largest wetland in Southwest Asia, the marshes are home to the native Ma’dan marsh dwellers, as well as numerous species of migrating waterfowl and game fish. Drainage of the wetlands as well as toxic contamination over the last twenty years d
The Beginnings of a New Phase in Medical Imaging? Phase-Contrast Imaging Device Provides 3-Dimensional Views of Hard-to-Image Biological Objects
In a development that could help usher in a new kind of medical imaging for clinics and hospitals, researchers have demonstrated a practical x-ray device that provides 2- and 3-dimensional images of features in soft biological tissue that are ordinarily hard to discern with conventional x-ray imaging. Performed by researchers at the Paul
The treatment of a lung condition that affects almost half of all pre-school children is to be investigated by researchers at the Universities of Nottingham and Leicester.
They aim to find a definitive answer on the best way of treating the tens of thousands of children brought into hospitals every year with unexplained wheezing and shortness of breath.
The condition affecting them, known as ‘viral-induced wheezing’, is one of the commonest reasons for young children to
Research on new materials and coatings in EUREKA project E! 2866 VASCUCHARGE will extend the life of synthetic vascular grafts from months to years, saving on average €7,000 per operation. As such grafts are used in around 500 out of each million vascular treatments in Europe, the savings could be considerable. Furthermore, the pain and discomfort suffered by patients is significantly reduced, as is the drain on health service resources.
The number of implants used in the surgical trea
By analysing ancient DNA, an international team of researchers has obtained data that increases our knowledge about how the large predatory cats that once roamed the prehistoric New World were related to each other.
The research, published today (9 August) in Current Biology, was carried out by Ross Barnett from the University of Oxford and a team of researchers from Britain, the United States, Canada, Sweden, and Australia.
North and South America were once home to a varie
Accurately forecasting rain will be easier thanks to new insights into clouds from the University of Leeds, UCL (University College London) and others. Details of a new model for predicting cloud and rain-formation are published today in the Proceedings of the Royal Society (10 August 2005).
Existing forecasting models – including ones used by the UK’s Meteorological Office – assume rain droplets fall through still air within a cloud. However, there is turbulence within cl
Is one man’s Mozart another man’s migraine? It might be, if culture plays the dominant role in music perception, as has been alleged by many 20th century composers. Thus far, such matters have been the province of armchair debates, but now two MIT students have designed an experiment to measure just how different-or similar-perceptions of music are across cultures.
The students are conducting a web-based Music Universals Study to measure the perception of music in people

Southern pines appear to grow and conserve water somewhat better in the carbon-dioxide-enriched atmosphere expected by mid-century, a Duke University study has found. However, any growth spurts appear to diminish over time, due at least in part to the kind of hot and dry weather that likely may become more common in the future. Thus, the researchers concluded, enhanced growth of pines may not constitute a long-term sink for human-produced carbon dioxide which might ameliorate global warming.
Physicists at The University of Texas at Austin have discovered a new technique for cooling atoms and molecules that will allow them to study quantum physics more effectively with a greater variety of particles.
The researchers have found a way to use lasers to form walls that allow atoms and molecules to pass through in one direction, but do not allow them to return.
The technique could lead to advances in atomic clocks, which are used to standardize time worldwide.
Even grizzly bears should watch what they eat. It turns out that grizzlies that gorge themselves on salmon during the summer spawning season have much higher levels of contaminants in their bodies than their cousins who rely more on berries, plants and insects, according to Peter Ross of Canada’s Department of Fisheries and Oceans.
Reporting in an article to be published Sept. 15 in the American Chemical Society journal, Environmental Science & Technology, Canadian researchers say
Scientists have used a glowing protein from fireflies to observe the activity of a molecule that is an important target for new drugs to treat cancer, autoimmune diseases and several other disorders.
The target molecule, known as IKK (for IKappa kinase), regulates processes that can trigger dramatic changes in cellular physiology. Scientists have linked these changes to many different disorders.
“Our new system allows researchers to monitor whether drugs for these condit
