In a new study, researchers present a “cautionary tale” about what may go wrong when using the fledgling science of proteomics to devise a diagnostic test for cancer.
In the February 16 issue of the Journal of the National Cancer Institute, researchers from The University of Texas M. D. Anderson Cancer Center detail why an experimental test intended to identify early ovarian cancer from a small sample of blood is unlikely to lead to a reliable clinical test right away.
New and effective treatments for lung cancer may rest on their ability to hinder the action of estrogen in lung cancer cells, according to two studies published in the current issue of Cancer Research. The University of Pittsburgh studies build on current knowledge about the relationship between estrogen and lung cancer growth and suggest that blocking estrogen may be vitally important to improving survival from the disease.
Since 1930, a 600 percent increase in death rates from
Researchers hope test increases early detection
Physicians now have a more dependable, less expensive tool to help detect bladder cancer earlier. Researchers at The University of Texas M. D. Anderson Cancer Center found that a simple test that can be administered and read in the doctor’s office was three times more effective than a conventional laboratory test for detecting bladder cancer.
In a study published in the February 16 issue of the Journal of the American Me
Researchers at Johns Hopkins have concluded that sudden, temporary spikes in the amount of HIV in the body, commonly called “blips,” generally do not mean the virus is developing resistance to AIDS drugs and gaining strength in numbers.
“These results should provide relief to hundreds of thousands of HIV-positive patients in the United States currently taking drug therapy, called highly active anti-retroviral therapy, or HAART, and reassure them that their medications have not fail
Supercapacitors that can deliver a strong surge of electrical power could be manufactured from carbon nanotubes using a technique developed by researchers at UC Davis.
Supercapacitors are electrical storage devices that can deliver a huge amount of energy in a short time. Hybrid-electric and fuel-cell powered vehicles need such a surge of energy to start, more than can be provided by regular batteries. Supercapacitors are also needed in a wide range of electronic and enginee
UC Davis researchers have discovered two key signals that tell fish how to handle the stress of changing concentrations of salt as they swim through different waters.
Not many fish can travel between saltwater and freshwater. To maintain the right internal salt level, their gills must pump up salt from freshwater but excrete it in the ocean. “Fish that can survive both environments are able to resist many kinds of stress,” said Dietmar Kueltz, an assistant professor of animal
Robots that act like rat pups can tell us something about the behavior of both, according to UC Davis researchers.
Sanjay Joshi, assistant professor of mechanical and aeronautical engineering, and associate professor of psychology Jeffrey Schank have recorded the behavior of rat pups and built rat-like robots with the same basic senses and motor skills to see how behavior can emerge from a simple set of rules.
Seven to 10-day-old rat pups, blind and deaf, do not seem t
In the first meeting of its kind, Australian industry, government, scientific, community and environmental groups will today come together to discuss the nation’s energy and transport future.
Participants of Australia’s Energy Futures Forum, holding it first full meeting in Canberra today, will begin the process of determining plausible scenarios and implications for the nation’s energy and transport future out to 2050.
Initiated by the CSIRO’s 
Understanding the dynamic process of adjustment of a country’s external balance is one of the most important questions for international economists. The recent wave of financial globalization has led to a sharp increase in cross-holdings of foreign assets and liabilities. The upsurge in cross-border holdings has therefore opened the door to potentially large wealth transfers across countries. In CEPR Discussion Paper No. 4923, Pierre-Olivier Gourinchas and Hélène Rey argue that to fully explain t
A key first step has been taken in the construction of IceCube, a giant neutrino telescope spanning a volume of one cubic kilometer of ice at the South Pole: Working under harsh Antarctic conditions, an international team of scientists, engineers and technicians – among them scientists from the DESY research center – has successfully deployed a first critical part of the telescope, a string of 60 optical detectors, in a 2.4-kilometer-deep hole drilled into the Antarctic ice. Comprising a total of
Scientists have turned to the brightest brains in Britain in a bid to understand the link between intelligence and dementia.
A team of researchers from The University of Manchester will be asking members of the high-IQ society Mensa for DNA samples in what will be the world’s most sophisticated study of brainpower. The research will allow the team to find genes associated with intelligence and examine how they interact with each other. “When you look at the genes in combination
Europe’s airplane engine manufacturers are now pooling their resources to make flying more environmentally friendly. In collaboration with some select universities and university colleges they are using millions in financial support from the EU to set up a major research project aiming to reduce noise, fuel use, and emissions. University of Trollhättan/Uddevalla, HTU is one of the project participants in Sweden.
This is the first time the university college has taken part as a f
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, show the central part of the 4000-kilometre long Valles Marineris canyon on Mars.
The HRSC obtained these images during during orbits 334 and 360 with a resolution of approximately 21 metres per pixel for the earlier orbit and 30 metres per pixel for the latter.
The scenes show an area of approximately 300 by 600 kilometres and are taken from an image mosaic that was
The Chemical Industries Association (CIA) today expressed concern that the UK’s allocation of greenhouse gas emissions is still not finally decided, but applauded the UK Government’s decision to press the European Commission for approval of the revised limits.
“The changes the UK Government has now suggested still leave industry in a more difficult position than with the original targets. It is vital that the UK secures the amendment to the current emissions cap; otherwise we risk further
An artificial eye developed for Earth observation is now being employed to recognise colour variations in dyed fabrics: a critical element of textile production. This could significantly reduce the 160 million metres of dyed fabrics discarded annually in Europe with high environmental costs.
“Today most of Europe’s more than 40,000 textile companies rely on human quality control. Specialised personnel monitor fabrics as they are produced, but this is an expensive and techn
Visiting the Earth and Space Expo in Brussels is like nowhere else on Earth – you even take what seems like a walk through the sky to get inside! During the weekend upwards of 9000 visitors made the journey to experience a wide range of displays, interactive exhibits and breathtaking space-based views of our planet.
Those entering the Expo, at Autoworld in the Parc du Cinquantenaire, find that carefully placed mirrors on the floor, walls and ceiling give a sense of spacewalking
