As a result, researchers have developed a solution to help avoid such an impact: a tool called namehelp that could speed web performance by 40 percent. Through a large-scale study involving more than 10,000 hosts across nearly 100 countries, Fabián Bustamante, associate professor of electrical engineering and computer science at Northwestern's McCormick School of Engineering and Applied Science, and his team found that one cause ...

This press release is available in German. Leipzig. Researchers from Germany and Slovakia have pointed out that the chemical triclosan is one of those particularly harmful substances for the ecological status of rivers that are still not sufficiently monitored. With extensive monitoring conducted in the Elbe river basin that was more comprehensive than standard monitoring procedures, concentrations of the chemical at numerous test sites exceeded the predicted no-effect concentration (PNEC) for algal communities up to a factor of twelve. From the 500 river basin-specific ...

MIAMI, FL – OCTOBER 25, 2012 – A study confirmed no differences in various measures of heart damage, according to cardiac magnetic resonance (MRI) imaging, in patients receiving the anti-clotting medication abxicimab directly into the heart (intracoronary) compared to those receiving it intravenously (IV). The results of the AIDA STEMI MRI sub-study were presented today the 24th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation, TCT is the world's premier educational meeting specializing in interventional ...

JOHANNESBURG, SOUTH AFRICA (October 25, 2012) – A recent report says illegal hunting of wildlife in South African Development Community (SADC) states can lead to the eradication of many species across extensive areas and even complete ecological collapse. Africa's iconic large carnivores, such as cheetah, lion, leopard, and wild dog, are particularly vulnerable to this practice, either because they are caught in the bycatch from unselective methods such as snaring, or due to loss of prey. The report says that the scale and severity of the threat is such that, without ...

(SACRAMENTO, Calif.) -- A team of UC Davis scientists has shown in experimental mouse models that a new drug delivery system allows for administration of three times the maximum tolerated dose of a standard drug therapy for advanced bladder cancer, leading to more effective cancer control without increasing toxicity. The delivery system consists of specially designed nanoparticles that home in on tumor cells while carrying the anti-cancer drug paclitaxel. The same delivery system also was successfully used to carry a dye that lights up on imaging studies, making it potentially ...

LA JOLLA, CA – October 25, 2012 – Explosive advancement in human genome sequencing opens new possibilities for identifying the genetic roots of certain diseases and finding cures. However, so many variations among individual genomes exist that identifying mutations responsible for a specific disease has in many cases proven an insurmountable challenge. But now a new study by scientists at The Scripps Research Institute (TSRI), Scripps Health, and Scripps Translational Science Institute (STSI) reveals that by comparing the genomes of diseased patients with the genomes of ...

CHESTNUT HILL, MA (October 25, 2012) – In the relatively new scientific frontier of topological insulators, theoretical and experimental physicists have been studying the surfaces of these unique materials for insights into the behavior of electrons that display some very un-electron-like properties. In topological insulators, electrons can behave more like photons, or particles of light. The hitch is that unlike photons, electrons have a mass that normally plays a defining role in their behavior. In the world of quantum physics, where everyday materials take on surprising ...

In the future, warmer waters could significantly change ocean distribution of populations of phytoplankton, tiny organisms that could have a major effect on climate change. Reporting in this week's online journal Science Express, researchers show that by the end of the 21st century, warmer oceans will cause populations of these marine microorganisms to thrive near the poles and shrink in equatorial waters. "In the tropical oceans, we are predicting a 40 percent drop in potential diversity, the number of strains of phytoplankton," says Mridul Thomas, a biologist at Michigan ...

EAST LANSING, Mich. — Warmer oceans in the future could significantly alter populations of phytoplankton, tiny organisms that could have a major impact on climate change. In the current issue of Science Express, Michigan State University researchers show that by the end of the 21st century, warmer oceans will cause populations of these marine microorganisms to thrive near the poles and may shrink in equatorial waters. Since phytoplankton play a key role in the food chain and the world's cycles of carbon, nitrogen, phosphorous and other elements, a drastic drop could have ...

HERSHEY, Pa. -- The zebrafish is a potential tool for testing one class of unique individual genetic differences found in humans, and may yield information helpful for the emerging field of personalized medicine, according to a team led by Penn State College of Medicine scientists. The differences, or mutations, in question create minor changes in amino acids -- the building blocks of DNA -- from person to person. Zebrafish can be used as a model to understand what biological effects result from these genetic mutations. Personalized medicine uses modern technology and ...

Astronomers using the NASA/ESA Hubble Space Telescope have obtained a remarkable new view of a whopper of an elliptical galaxy, with a core bigger than any seen before. There are two intriguing explanations for the puffed up core, both related to the action of one or more black holes, and the researchers have not yet been able to determine which is correct. Spanning a little over one million light-years, the galaxy is about ten times the diameter of the Milky Way galaxy. The bloated galaxy is a member of an unusual class of galaxies with an unusually diffuse core filled ...

UNIVERSITY PARK, Pa. -- Had a bad day? Extending your normal exercise routine by a few minutes may be the solution, according to Penn State researchers, who found that people's satisfaction with life was higher on days when they exercised more than usual. "We found that people's satisfaction with life was directly impacted by their daily physical activity," said Jaclyn Maher, graduate student in kinesiology. "The findings reinforce the idea that physical activity is a health behavior with important consequences for daily well-being and should be considered when developing ...

Robots have the potential to help older adults with daily activities that can become more challenging with age. But are people willing to use and accept the new technology? A study by the Georgia Institute of Technology indicates the answer is yes, unless the tasks involve personal care or social activities. After showing adults (ages 65 to 93 years) a video of a robot's capabilities, researchers interviewed them about their willingness for assistance with 48 common household tasks. Participants generally preferred robotic help over human help for chores such as cleaning ...

A large international study has identified three new gene variants associated with body mass index (BMI) levels in adults. The scientific consortium, numbering approximately 200 researchers, performed a meta-analysis of 46 studies, covering gene data from nearly 109,000 adults, spanning four ethnic groups. In discovering intriguing links to lipid-related diseases, type 2 diabetes and other disorders, the IBC 50K SNP Array BMI Consortium's study may provide fundamental insights into the biology of adult obesity. Scientists from the Center for Applied Genomics at The Children's ...

Universities not only provide the ideal petri dish for cultivating bioscience with commercial potential, but have a moral obligation to do so, given the opportunity to translate public funding into health and jobs, according to a new case study by UCSF researchers. In an analysis published Oct. 24, 2012 in Science Translational Medicine, researchers at the California Institute for Quantitative Biosciences (QB3) assessed the impact of the institute's efforts over the past eight years in supporting entrepreneurs on the three UC campuses in which it operates: UCSF, UC Berkeley ...

Five scientists, including two from Simon Fraser University, have discovered that 30 per cent of our likelihood of developing Multiple Sclerosis (MS) can be explained by 475,806 genetic variants in our genome. Genome-wide Association Studies (GWAS) commonly screen these variants, looking for genetic links to diseases. Corey Watson, a recent SFU doctoral graduate in biology, his thesis supervisor SFU biologist Felix Breden and three scientists in the United Kingdom have just had their findings published online in Scientific Reports. It's a sub-publication of the journal ...

A new University of Michigan study shows that when researchers share a building, and especially a floor, the likelihood of forming new collaborations and obtaining funding increases dramatically. The findings have wide relevance to corporations, as well. "Our analyses clearly show that there are benefits to co-location," said Jason Owen-Smith, an associate professor of sociology and organizational studies. Researchers who occupy the same building are 33 percent more likely to form new collaborations than researchers who occupy different buildings, and scientists who ...

A second look at data from NASA's Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet. The study suggests that the planet, named Fomalhaut b, is a rare and possibly unique object that is completely shrouded by dust. "Although our results seriously challenge the original discovery paper, they do so in a way that actually makes the object's interpretation much cleaner and leaves intact the core conclusion, that Fomalhaut b is indeed a massive planet," said Thayne Currie, an astronomer formerly at NASA's Goddard Space ...

NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought. Data from Cassini's composite infrared spectrometer (CIRS) instrument revealed the storm's powerful discharge sent the temperature in Saturn's stratosphere soaring 150 degrees Fahrenheit (83 kelvins) above normal. At the same time, researchers at NASA's Goddard Space Flight ...

RIVERSIDE, Calif. — Assassin bugs, so named because these insects lie in ambush for prey that they attack with speed and precision, are found all over the world. Nearly 140 species of these bugs are blood-sucking; because they can bite humans around the mouth, they are also called kissing bugs. All kissing bugs can spread Chagas disease, a neglected tropical disease that imposes an economic burden on society. Surprising, then, that scientists' understanding of the evolutionary history of assassin bugs is riddled with difficulty. The data are incomplete. Fossils, which ...
