The work carried out by these scientists has ranged from the initial design of an electronic architecture for gamma ray detectors to industry transfer of a complete scanner, after having adequately validated a prototype through experimental studies at the Gregorio Marañón Hospital. The results of this research, headed by professors Juan José Vaquero and Manuel Desco, from the Department of de Bioengineering and Aerospace Engineering at UC3M, have been recently published in the journals IEEE Transactions on Nuclear Science (two articles) and Physics in Medicine and Biology ...

WASHINGTON -- Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before. Scientists think the antimatter particles were formed in a terrestrial gamma-ray flash (TGF), a brief burst produced inside thunderstorms and shown to be associated with lightning. It is estimated that about 500 TGFs occur daily worldwide, but most go undetected. "These signals are the first direct evidence that thunderstorms make antimatter particle beams," said Michael Briggs, a member of Fermi's ...

It remains an unresolved issue as to whether interstitial brachytherapy has advantages compared to other therapy options in men with localized prostate cancer, nor do newer studies provide proof in this respect. This is the result of a report published by the Institute for Quality and Efficiency in Health Care (IQWiG) on 11 January 2011. In this report IQWiG examined whether newer studies challenged the findings of research already completed in 2007. However, it was shown that no relevant new evidence could be obtained from the recent studies. The conclusions of the final ...

Smoking is a common problem for patients with schizophrenia. The increased tendency of patients diagnosed with this disorder is to not only smoke, but to do so more heavily than the general public. This raises the possibility that nicotine may be acting as a treatment for some symptoms of schizophrenia. Nicotine acts through two general classes of brain receptors, those with high and low affinity for nicotine. The low affinity class of nicotinic receptors contains the alpha-7 subunit, which is present in reduced numbers in people with schizophrenia. Two papers published ...

The first scientific results from Europe's Planck spacecraft featuring the coldest objects in the Universe have today been released. Astronomers at The University of Manchester's Jodrell Bank Observatory played a key role in the worldwide teams searching for an exciting variety of astronomical finds, from massive galaxy clusters to new, unidentified objects. Ranging from within our Galaxy to the most distant reaches of space, Planck is a flagship mission of the UK Space Agency, which funds the UK's involvement in both of Planck's scientific instruments. Astronomers ...

The negative reaction to Starbucks' redesigned logo by the company's self-described most loyal customers may be attributable to the strong connection Starbucks' consumers feel toward the brand, according to research co-authored by a professor at Penn State's Smeal College of Business. Karen Winterich, assistant professor of marketing at Smeal, and researchers Michael Walsh of West Virginia University and Vikas Mittal of Rice University recently examined how consumers react to logo redesigns. They found that consumers who are strongly committed to a brand tend to react ...

Researchers at the University of Tennessee, Knoxville, continue to chip away at the mysterious existence of water on the moon -- this time by discovering the origin of lunar water. Larry Taylor, a distinguished professor in the Department of Earth and Planetary Sciences, was the one last year to discover trace amounts of water on the moon. This discovery debunked beliefs held since the return of the first Apollo rocks that the moon was bone-dry. Then, he discovered water was actually pretty abundant and ubiquitous -- enough so a human settlement on the moon is not ...

BETHESDA, Md., Jan. 11, 2011 – An international team of researchers is reporting that it has uncovered new information about human papillomavirus that one day may aid in the development of drugs to eliminate the cervical-cancer-causing infection. Led by researcher Per Jemth of Uppsala University in Sweden, the collaborators from four institutions detail in the Journal of Biological Chemistry how an offensive protein generated by the sexually transmitted virus handicaps a defensive protein made by the human body. Co-author Neil Ferguson, a biophysicist at University ...

The first scientific results from Europe's Planck spacecraft were released at a press briefing today in Paris. The findings, focusing on the coldest objects in the Universe - both within our galaxy and also out to the most distant reaches of space - include an exciting variety of astronomical finds, from massive galaxy clusters to new, unidentified objects. Planck is a flagship mission of the UK Space Agency, which funds the UK's involvement in both of Planck's scientific instruments. Astronomers from around the UK are now heavily involved in the operation of Planck's ...

PROVIDENCE, RI – Does obesity tend to "cluster" among young adults? And if so, what impact does it have on both their weight and weight-related behaviors? That's what researchers from The Miriam Hospital's Weight Control and Diabetes Research Center set out to answer to better understand how social influences affect both weight status and weight loss intentions in this difficult-to-reach age group. According to the study, published online by the journal Obesity, overweight and obese young adults between the ages of 18 and 25 were more likely to have overweight romantic ...

Andrew Wakefield, the disgraced doctor who claimed a link between MMR and autism, planned secret businesses intended to make huge sums of money, in Britain and America, from his now-discredited allegations. The Wakefield scheme is exposed today in the second part of a BMJ series of special reports, "Secrets of the MMR scare", by investigative journalist Brian Deer. Last week we revealed the scientific fraud behind the appearance of a link between the vaccine and autism. Now Deer follows the money. Drawing on investigations and documents obtained under the Freedom of ...

The drugs include traditional non-steroidal anti-inflammatory drugs (NSAIDS) as well as new generation anti-inflammatory drugs, known as COX-2 inhibitors. The researchers say that doctors and patients need to be aware that prescription of any anti-inflammatory drug needs to take cardiovascular risk into account. NSAIDs have been the cornerstone of managing pain in patients with osteoarthritis and other painful conditions. In 2004, the COX-2 inhibitor rofecoxib was withdrawn from the market after a trial found that the drug increased the risk of cardiovascular disease. ...

The blood test could mean that 98% of invasive procedures could be avoided, say the authors. The test uses the latest DNA technology to analyse genetic components in the mother's blood that indicate whether the foetus has Down's. Down's syndrome or trisomy 21 occurs in around 1 in 800 births and older women are at higher risk. Women in high risk groups tend to undergo a combination of scans and hormone level tests in order to determine if they need to have an invasive test such as amniocentesis or chorionic villus sampling. The latter tests take samples of genetic ...

Cambridge, MASS. -- Researchers at MIT and Brigham and Women's Hospital have shown that they can deliver the cancer drug cisplatin much more effectively and safely in a form that has been encapsulated in a nanoparticle targeted to prostate tumor cells and is activated once it reaches its target. Using the new particles, the researchers were able to successfully shrink tumors in mice, using only one-third the amount of conventional cisplatin needed to achieve the same effect. That could help reduce cisplatin's potentially severe side effects, which include kidney damage ...

Tom Jefferson and colleagues from the Cochrane Group argue that the current system for assessing the safety and effectiveness of drugs, based on published trial data only, is "wholly inadequate" and "ethically dubious." They propose a new approach that would allow in-depth scrutiny of the complete set of trial data for a new drug. Their call comes after they reviewed the evidence for the antiviral drug oseltamivir (Tamiflu), and were unable to find sufficient published data to support the conclusion that oseltamivir reduces complications in healthy adults. As a result, ...

CHICAGO—Hearing loss can affect anyone, at any time. But it can be especially frightening for someone who suddenly starts to lose his hearing during adulthood. Tom Groves, 77, first noticed his diminishing hearing when he was in his early 40s. He was unable to hold conversations with large groups of people; found it nearly impossible to socialize in high-background noise environments like restaurants; and couldn't enjoy radio, TV and movies unless they were captioned. Now, Groves is hearing much better than he has in 30 years, thanks to an experimental hybrid cochlear implant. ...

Gender stereotypes suggest that men are usually tough and women are usually tender. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds these stereotypes have some real bodily truth for our brains; when people look at a gender-neutral face, they are more likely to judge it as male if they're touching something hard and as female if they're touching something soft. Several studies have found recently that we understand many concepts through our bodies. For example, weight conveys importance; just giving someone ...

"Vive la difference!" Seeing foreigners as foreign encourages local coworkers to assist them finds a Rotman study. Toronto - Whether it's a company with local and ex-pat employees, countries in need of aid, or the elderly interacting with the young, a new research paper to be published in the journal Psychological Science says recognizing diversity can actually encourage people to help each other instead of sparking conflict. "The standard assumption has been that group-based differences serve as the basis for distrust, disagreement, or dispute," says Geoffrey Leonardelli, ...

(Boston) – Researchers from Boston University School of Medicine (BUSM), in collaboration with colleagues at Lahey Clinic and from Denmark and Germany, have found that 5a-reductase inhibitors (5a-RIs), while improving urinary symptoms in patients with benign prostatic hyperplasia (BPH) and possible hair loss prevention, produces significant adverse effects in some individuals including loss of libido, erectile dysfunction (ED), ejaculatory dysfunction and potential depression. These findings, which currently appear on-line in Journal of Sexual Medicine, suggest that extreme ...

New research suggests eating vegetables gives you a healthy tan. The study, led by Dr Ian Stephen at The University of Nottingham, showed that eating a healthy diet rich in fruit and vegetables gives you a more healthy golden glow than the sun. The research, which showed that instead of heading for the sun the best way to look good is to munch on carrots and tomatoes, has been published in the journal Evolution and Human Behaviour. Dr Ian Stephen, from the School of Psychology, University of Nottingham, Malaysia Campus, led the research as part of his PhD at the University ...

Montreal, January 10, 2011 – A research team from the McGill University Health Centre (MUHC) and McGill University has demonstrated that private rooms in the Intensive Care Unit (ICU) play a key role in reducing hospital infections like C-difficile. The study, published today in the journal Archives of Internal Medicine, also suggests that length of stay would be shorter and this could lead to cost savings to the healthcare system. Infection control in hospitals is a worldwide health concern that can have a serious impact on patient morbidity, mortality and the cost of ...

Many futurists envision a world in which polymer membranes with molecular-sized channels are used to capture carbon, produce solar-based fuels, or desalinating sea water, among many other functions. This will require methods by which such membranes can be readily fabricated in bulk quantities. A technique representing a significant first step down that road has now been successfully demonstrated. Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have developed a solution-based ...

Cancer researchers at The Peggy and Charles Stephenson Oklahoma Cancer Center have found a way to stop early stage pancreatic cancer in research models – a result that has far-reaching implications in chemoprevention for high-risk patients. The research already has sparked a clinical trial in California, and the FDA-approved drug, Gefitinib, should be in clinical trials at OU's cancer center and others nationwide in about a year. The research appears in the latest issue of Cancer Prevention Research, a journal of the American Association for Cancer Research. C.V. Rao, ...

The results of a study recently published in the journal Biology Letters indicate that giant pandas need old-growth forests as much as bamboo forests. This work, which was completed through the collaborative efforts of scientists from the Chinese Academy of Science, San Diego Zoo Global, China West Normal University, China Wildlife Conservation Association and the Sichuan Forestry Department, could assist conservationists in creating strategic plans that help conserve this critically endangered bear species. "In this study we show that pandas are associated with old-growth ...
