A gene thought to be responsible for initiating human cancer has been identified by researchers at Barts and The London School of Medicine and Dentistry. The study - published online today (9 November) in the journal Cancer Research - paves the way for developing early cancer diagnostic tests, and finding new treatments that prevent or stop the spread of cancer cells at an early stage. Led by Dr Muy-Tek Teh of the Institute of Dentistry at Barts and The London School of Medicine and Dentistry researchers have shown that a gene called FOXM1 exploits the inherent self-renewal ...

BOSTON, MA (Nov. 9, 2010) - With so few Americans consuming the recommended amounts of fruit each day, finding quick and simple ways to add additional fruit servings – and the important nutrients they provide – is more critical than ever. Although USDA recognizes that 4-oz of 100 percent juice supplies one serving (1/2 cup) of fruit, there is still confusion regarding the healthfulness of juice. New research presented today at the American Dietetic Association (ADA) Annual Food and Nutrition Conference and Expo (FNCE) clearly highlights the benefits of 100 percent juice, ...

CLEVELAND – November 9, 2010—Texting while driving can be a deadly combination for anyone. Yet, new data released today reveal that the dangers of excessive texting among teens are not limited to the road. Hyper-texting and hyper-networking are now giving rise to a new health risk category for this age group. Scott Frank, MD, MS, lead researcher on the study and director of the Case Western Reserve School of Medicine Master of Public Health program, presented the findings today at the American Public Health Association's 138th Annual Meeting & Exposition in Denver. Researchers ...

Young children who don't like school are more likely to be involved in underage drinking and sexual activity. A study reported in BioMed Central's open access journal Substance Abuse, Treatment, Prevention and Policy, has found that pupils' general wellbeing and specific satisfaction with school were both associated with the incidence of risky behaviors. Professor Mark Bellis worked with a team of researchers from the Centre for Public Health, Liverpool John Moores University, to carry out the study in more than 3500 11-14 year olds from 15 schools in the North West of ...

While policy and research traditionally have focused on universities' contributions to technology transfer - such as patents, licences and spin-outs - the findings show that the impact from knowledge exchange is much more wide-ranging. Survey data revealed that business motivations to enter into partnerships with researchers include service development, human resource management, training and marketing. "Our findings show that technology transfer is important, but this presents an incomplete representation of the wide process of knowledge exchange that takes place between ...

Your postcode could affect your risk of dying from a heart attack, a new study from the University of Leicester has discovered. Medical researchers from the University set out to determine why death rates from coronary heart disease (heart attacks) varied around the country and found that living in a deprived area contributed to your risk. The study has for the first time established an association at national level between detection of hypertension and death rates from coronary heart disease. The Leicester team, from the Department of Health Sciences, analysed whether ...

Researchers at the University of Derby and colleagues at the University of Cambridge believe they have found which species has the largest testicles in relation to body weight on the planet – and why! Yet the research team also discovered that large testes did not necessarily relate to a larger amount of sperm produced – which goes against traditional thinking in the science world. Biologists at the University of Derby, which led the research project, say that the Tuberous Bushcricket (Platycleis affinis) produces testes which are 14% of the male body mass, according ...

Carotenoid pigments are the source of many of the animal kingdom's most vivid colours; flamingos' pink feathers come from eating carotenoid-containing shrimps and algae, and carotenoid colours can be seen among garden birds in blackbirds' orange beaks and blue tits' yellow breast feathers. These pigments play a crucial role in sexual signals. According to the study's lead author Dr Tom Pike of the University of Exeter: "Females typically use carotenoid colours to assess the quality of a potential mate, with more colourful males generally being regarded as the most attractive." This ...

A simple "how are you" delivered weekly through cell phone text messaging (SMS) increases the likelihood that Kenyans with HIV will stay healthy and follow their medication regimen, while reducing the spread of the disease, according to a new study led by a University of British Columbia researcher. Published online today in The Lancet, the study found that patients in Kenya who received weekly SMS “check-ins” were 12 per cent more likely than a control group to have an undetectable level of the HIV virus a year after starting antiretroviral (ART) treatment. Undetectable ...

(GLASGOW, 9 November 2010) – Results from a European Observational Study, which included 1,294 antiretroviral (ARV)-experienced patients presented today at the Tenth International Congress on Drug Therapy in HIV Infection (HIV10), demonstrated a low rate of discontinuation and sustained virologic suppression with REYATAZ® (atazanavir)/ritonavir-based regimens over a follow-up period of up to five years.1 The aim of this study was to investigate the long-term outcomes of REYATAZ/ritonavir-containing regimens in ARV-experienced patients in a real-life clinical setting. ...

In a study of more than 9,600 adolescent and young adult women in the Baltimore area, researchers at the University of Maryland School of Medicine have found that fewer than 30 percent of those eligible to receive the human papillomavirus (HPV) vaccine to prevent cervical cancer actually chose to get it. And only about a third of those who began receiving the vaccine completed the three doses recommended for maximum protection. The research, which was led by J. Kathleen Tracy, Ph.D., an assistant professor of epidemiology, will be presented on Nov. 9, 2010, at a cancer ...

Washington, D.C. (November 9, 2010) -- Current medical techniques for monitoring the heart rate and other vital signs use electrodes attached to the body, which are impractical for patients who want to move around. Plasma physicist Atsushi Mase, a scientist at Kyushu University in Japan, and colleague Daisuke Nagae have developed a new technique to disconnect people from their electrodes by using microwaves. The work, which could lead to the development of non-invasive, real-time stress sensing in a variety of environments, is described in a recent issue of the journal ...

Washington, D.C. (November 9, 2010) -- A switch to wind energy will help reduce greenhouse gas emissions -- and reduce the global warming they cause. But there's a catch, says climate researcher Diandong Ren, a research scientist at the University of Texas at Austin in a paper appear in the AIP's Journal of Renewable and Sustainable Energy: rising temperatures decrease wind speeds, making for less power bang for the wind turbine buck. The prevailing winds in the "free" atmosphere about 1,000 meters above the ground are maintained by a temperature gradient that decreases ...

Washington, D.C. (November 9, 2010) -- Microscopically porous polymer membranes have numerous applications in microfluidics, where they can act as filters, masks for surface patterning, and even as components in 3D devices in which the perforations in stacked membranes are aligned to form networks of channels for the flow of fluids. In the AIP journal Biomicrofluidics, Hongkai Wu, a chemist at Hong Kong University of Science and Technology, and his colleagues describe a simple new method using just one photolithographic step to fabricate free-standing polymer membranes ...

Washington, D.C. (November 9, 2010) -- Researchers at the University of Maryland have proposed a scheme for detecting a concealed source of radioactive material without searching containers one by one. Detection of radioactive material concealed in shipping containers is important in the early prevention of "dirty" bomb construction. The concept, described in the Journal of Applied Physics, is based on the gamma-ray emission from the radioactive material that would pass through the shipping container walls and ionize the surrounding air. The facilitated breakdown of ...

Washington, D.C. (November 9, 2010) -- Walk into nearly any science museum worth its salt and you're likely to see a Foucault pendulum, a simple but impressive device for observing the Earth's rotation. Such pendulums have been around for more than 150 years, and little about how they work remains a mystery today. The only problem, according to Argentinean researcher Horacio Salva, is that the devices are generally large and unwieldy, making them impractical to install in places where space is at a premium. This limitation was something he and his colleagues at the Centro ...

At the current pace of research and development, global oil will run out 90 years before replacement technologies are ready, says a new University of California, Davis, study based on stock market expectations. The forecast was published online Monday (Nov. 8) in the journal Environmental Science & Technology. It is based on the theory that long-term investors are good predictors of whether and when new energy technologies will become commonplace. "Our results suggest it will take a long time before renewable replacement fuels can be self-sustaining, at least ...

A team of international researchers led by ancient DNA experts from the University of Adelaide has resolved the longstanding issue of the origins of the people who introduced farming to Europe some 8000 years ago. A detailed genetic study of one of the first farming communities in Europe, from central Germany, reveals marked similarities with populations living in the Ancient Near East (modern-day Turkey, Iraq and other countries) rather than those from Europe. Project leader Professor Alan Cooper, Director of the Australian Centre for Ancient DNA (ACAD) at the University ...

Astronomers at The University of Warwick and the University of Sheffield have helped discover an unusual star system which looks like, and may even once have behaved like, a game of snooker. The University of Warwick and Sheffield astronomers played a key role in an international team that used two decades of observations from many telescopes around the world. The UK astronomers helped discover this "snooker like" star system through observations and analysis of data from an astronomical camera known as ULTRACAM designed by the British researchers on the team. They ...

Kyoto, Japan -- As if borrowing from a scene in a science fiction movie, researchers at Kyoto University have successfully developed a kind of tractor beam that can be used to manipulate the network of the molecules. In a paper soon to be published in Physical Review Letters, the team has demonstrated a technique using terahertz pulses that could have broad applications in the chemical and pharmaceutical industries. Terahertz waves, an area of specialty for the Koichiro Tanaka lab at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS), exist in ...

A recommendation letter could be the chute in a woman's career ladder, according to ongoing research at Rice University. The comprehensive study shows that qualities mentioned in recommendation letters for women differ sharply from those for men, and those differences may be costing women jobs and promotions in academia and medicine. Funded by the National Science Foundation, Rice University professors Michelle Hebl and Randi Martin and graduate student Juan Madera, now an assistant professor at the University of Houston, reviewed 624 letters of recommendation for 194 ...

Membrane-associated receptors, channels and transporters are among the most important drug targets for the pharmaceutical industry. The search for new drugs resembles looking for a needle in a haystack. Therefore new analytical techniques are required which facilitate the simultaneous screening of a large library of compounds across a variety of membrane proteins. However, this class of methods is still at the early stages of development. The group of Prof. Dr. Robert Tampé, in collaboration with the Walter Schottky Institute at Technical University Munich, has now presented ...

Quantum computers should be much easier to build than previously thought, because they can still work with a large number of faulty or even missing components, according to a study published today in Physical Review Letters. This surprising discovery brings scientists one step closer to designing and building real-life quantum computing systems – devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking. Scientists have long been fascinated with building computers that work at a quantum level – so small ...

Click here for more information. "How do hearts, wings or flowers get their shape?" asks Professor Enrico Coen from the John Innes Centre. " Unlike man-made things like mobile phones or cars, there is no external hand or machine guiding the formation of these biological structures; they ...

This release is available in German. Hormones, growth factors and several proteins ensure that development occurs in the right way, at the right time. The components that cause breast development in mammals, for example, were thought to be largely known. However, as a team of scientists from Göttingen, Frankfurt and Hanover have now discovered, in the case of breast development, hormones and proteins do not account for the full story. The scientists have shown that tiny ribonucleic acid molecules play a key role in this process. The mammary glands of mice lacking the ...
