New observations from the Cassini spacecraft now at Saturn indicate the particles comprising one of its most prominent rings are trapped in ever-changing clusters of debris that are regularly torn apart and reassembled by gravitational forces from the planet.
According to University of Colorado at Boulder Professor Larry Esposito of the Laboratory for Atmospheric and Space Physics, particle clusters in the outermost main ring, the A ring, range from the size of sedans to movin
A Canadian-led study involving researchers from 41 countries has demonstrated in a study of acute coronary syndromes (ACS) that a new anti-thrombotic therapy is safer and as effective as the traditional therapy used in preventing heart attacks, death and ischemia in people with serious heart conditions.
The OASIS-5/MICHELANGELO study, presented today at the European Society of Cardiology meeting in Stockholm, Sweden, showed that fondaparinux, a new anti-thrombotic therapy, was
A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it – and identified one gene in particular, B-myb, whose function is essential to preventing tumors.
The findings were published in a professional journal, Proceedings of the National Academy of Sciences, by researchers from Oregon State University and two Boston hospitals, the Brigham and Women’s H
There are 2.6 million miles of paved roads in the United States, and new roads are being constructed daily. When parking lots and driveways are factored in, there is already enough blacktopped surface in the U.S. to cover the entire state of Ohio. Paved roads and parking spaces come in handy for our nation’s drivers, but they also come with a serious unforeseen cost— the degradation of our nation’s freshwater ecosystems.
In a recent Proceedings of the National Academy of Scienc
Recent research results from scientists at the Woods Hole Research Center suggest that ’greening’ has begun to decline in the high latitude forested areas of North America. The work, which represents an important advance by incorporating the full extent of the latest satellite observational record to document unique vegetation responses to climatic warming, and then projecting those trends forward in time, is now being extended to circumpolar forests. The research will be highlighted in u

A treatment program that stresses maintaining a regular schedule of daily activities and stability in personal relationships is an effective therapy for bipolar disorder, report University of Pittsburgh School of Medicine researchers in September’s Archives of General Psychiatry. Interpersonal and Social Rhythm Therapy (IPSRT), a novel approach developed by the University of Pittsburgh resea
Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast. But new research from the Stanford University School of Medicine suggests that looking at the immune cells in those lymph nodes – instead of the tumor cells – will yield a more accurate forecast. The finding could help clinicians determine which cancers to treat more aggressively to ensure the cancer goes away and doesn’t come back.
Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.

JUPITER II is an international multi-centre, double blind, randomized clinical trial designed to evaluate the safety and efficacy of JANUS Tacrolimus-eluting Carbostent in the treatment of coronary lesions in “direct stenting” procedures as compared to TECNIC Carbostent. A total of 332 patients were enrolled in 16 European centers and randomized to either JANUS (166 patients) or TECNIC (166 patients). Enrolment was completed on 21 December 2004 and direct stenting was performed in 86.1% of proce
Repeat interventions to treat restenosis are the Achilles heal of stenting. The new drug-eluting stents (DES) have reduced the need for repeat interventions significantly compared to bare-metal stents (BMS), however, they are so much more expensive, that their use in all patients threatens to ‘kill’ hospital budgets. This has led to difficult discussions among physicians, patients and hospital administrators with regard to who should or could get DES and it was questioned whether withholding DES fo
A recently completed EU project developed better tools for integrated microcircuit design; achieved some world firsts in performance analysis and now may even spin off a new company to commercialise some of its new technologies.
The DEMAND project wanted to develop a reliable and cost-effective design process for ‘smart power’ integrated circuits. This type of microchip can integrate a wide variety of functions into one piece of silicon. The advantage is lower-cost and increased r
The molecular biologist Cathrine Persson at Umeå University has been allotted SEK 2.5 million from the U.S. National Institutes of Health (NIH) for research on a vaccine against malaria.
The project “Immunogenicity of synthetic peptide malaria vaccines” spans five years and is designed to study the protection offered by various synthetic vaccines against malaria. Cathrine Persson is collaborating with Professor Elizabeth Nardin, NYU School of Medicine in New York.
As of October 1 this year the EU requires that emissions of nitrogen oxides be reduced by 30 percent in trucks and 50 percent in diesel-powered cars. In 2008 these regulations will be become more stringent in Europe, and even more so in the US. The technical solution chosen by nearly all automakers to meet the requirements was originally developed by the Lund University in Sweden. Now these researchers are working on methods to reduce nitrogen oxide emissions even more.
Emissions of nitrog
The Technical Research Centre of Finland, VTT has developed a new method, which increases product development cycle. This process will also enhance the competitiveness of drug development and reduce costs. VTT is working in collaboration with GlaxoSmithKline, GSK, one of the leading international pharmaceutical companies, to enhance quality control for drugs by using Process Analytical Technologies (PAT). The goal of the PAT is to develop drug process’ production analysis into real-time qu
The link between humans and animals may be closer than we may have realised. Research by Liverpool John Moores University (LJMU) has found that our furry relatives may share many of the same emotions that humans experience in everyday life.
Dr Filippo Aureli, reader in Animal Behaviour and co-director of the Research Centre in Evolutionary Anthropology and Palaeoecology at LJMU will present his findings today (September 6) at the BA Festival of Science in Dublin.

Government efforts to increase employment by reforming incapacity benefits are likely to have a limited impact unless accompanied by more effective regional policies to create new jobs in Britain’s older industrial areas, according to a new report published by the thinktank Catalyst, and authored by academics at Sheffield Hallam and Cambridge Universities.
The government believes that many of the 2.7 million people on incapacity benefits could take up work, and sees this as a
