Researchers at the University of Liverpool have shown for the first time that WiFi networks can be infected with a virus that can move through densely populated areas as efficiently as the common cold spreads between humans. The team designed and simulated an attack by a virus, called "Chameleon", and found that not only could it spread quickly between homes and businesses, but it was able to avoid detection and identify the points at which WiFi access is least protected by encryption and passwords. Researchers from the University's School of Computer Science and Electrical ...

A new study led by the University of Exeter and Swansea University has pinpointed the changes in the brain that lead gamblers to react in the same way to near-misses as they do to winning. The research shows that near-misses are underpinned by increases in the brain's electrical activity, particularly in the theta frequency range - known to be involved in processing win and loss outcomes. They found that these increases in theta are linked to both how severe someone's gambling history is and how susceptible they might be to developing a future gambling problem. Popular ...

An estimated three-quarters of camels recently surveyed in Saudi Arabia have evidence of infection with the Middle East Respiratory Syndrome coronavirus (MERS-CoV), the virus responsible for human cases of MERS. Results of the new study establish for the first time that direct camel-to-human transmission is possible and provide a pathway to control the spread of the disease. Results in the journal mBio are reported by scientists at the Center for Infection and Immunity at Columbia University's Mailman School of Public Health; Mammals Research Chair, King Saud University, ...

MILWAUKEE – After having recently discovered a new way to propagate multiple beams of light through a single strand of optical fiber, engineers at the University of Wisconsin-Milwaukee (UWM) now have found that their novel fiber architecture can transmit images with a quality that is comparable or better than the current commercial endoscopy imaging fibers. Because of this, the work has potential not only in next-generation high-speed communication, but also biomedical imaging. The work is published today in the journal Nature Communications. In conventional optical ...

Previous research has found that emotions affect eating, and that negative moods and positive moods may actually lead to preferences for different kinds of foods. For example, if given the choice between grapes or chocolate candies, someone in a good mood may choose the former while someone in a bad mood may choose the latter. The research reported in this article looks at the "why:" Why, when someone is in a bad mood, will they choose to eat junk food and why, when someone is in a good mood, will they make healthier food choices? To get at the "why," we married the ...

Acetaminophen, found in over-the-counter products such as Excedrin and Tylenol, provides many people with relief from headaches and sore muscles. When used appropriately, it is considered mostly harmless. Over recent decades, the drug, which has been marketed since the 1950s, has become the medication most commonly used by pregnant women for fevers and pain. Now, a long-term study by UCLA, in collaboration with the University of Aarhus in Denmark, has raised concerns about the use of acetaminophen during pregnancy. In a report in the current online edition of ...

(SALT LAKE CITY)—Cancer of the pancreas is usually not detected until it's too late to cure. But precursor lesions that form in the pancreas and its ducts can signal the disease before it strikes, and when caught early enough, they can be prevented from progressing to become cancer. In a new study, researchers led by a molecular biologist at the University of California, San Francisco (UCSF), report two breakthroughs in understanding those lesions and their role in pancreatic cancer: the development of the first mouse model that simulates a precursor lesion called intraductal ...

Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe. The team of scientists that made the discovery includes astronomers at Penn State University and other institutions. The astronomers detected the water in the atmosphere of a planet as massive as Jupiter that is orbiting the nearby star tau Boötis. The discovery is described in a scientific paper published in the 24 February 2014 online version of The Astrophysical ...

MAYWOOD, Ill. – A new blood test can detect heart attacks hours faster than the current gold-standard blood test, according to a study led by Loyola University Chicago Stritch School of Medicine researchers. The new test measures a protein that is released to the bloodstream by dying heart muscle. The protein is called cardiac myosin binding protein-C (cMyBP-C). The study found that cMyBP-C is released to the blood within just 15 minutes of cardiac damage, and rises to significant levels in three hours. "This is a potential ultra-early biomarker that could confirm whether ...

MAYWOOD, IL – A vascular disease called fibromuscular dysplasia, which can cause high blood pressure, kidney failure, stroke and other symptoms -- mostly in women -- is "poorly understood by many healthcare providers," according to a Scientific Statement from the American Heart Association. Neurologist Jose Biller, MD, of Loyola University Medical Center, is a co-author of the statement, published online ahead of print in the American Heart Association journal Circulation. First author is Jeffrey W. Olin, DO of Mount Sinai School of Medicine. Biller said FMD "is a ...

A team of computer scientists at the University of California, San Diego, has taken an unprecedented, in-depth look at how malware operators use the computers they infect to mine Bitcoin, a virtual currency whose value is highly volatile. Researchers examined more than 2,000 pieces of malware used by Bitcoin mining operations in 2012 and 2013. They were able to estimate how much money operators made off their operations and which countries were most affected. The computer scientists report that the revenue of 10 of the mining operations they studied reached at least 4,500 ...

A team of volunteers ate half a kilo of strawberries a day for a month to see whether it altered their blood parameters in any way. At the end of this unusual treatment, their levels of bad cholesterol and triglycerides reduced significantly, according to the analyses conducted by Italian and Spanish scientists. Several studies had already demonstrated the antioxidant capacity of strawberries, but now researchers from the Università Politecnica delle Marche (UNIVPM, Italy), together with colleagues from the Universities of Salamanca, Granada and Seville (Spain), conducted ...

There are clear advantages to living in cities: safety, ready availability of infrastructure, plenty of company etc. Nevertheless, a large number of people eschew them for the benefits of country life, such as clean air and lots of space. Many species of animals, and particularly birds, face the same choice between living in large groups or remaining in smaller ones, thereby avoiding disadvantages of larger colonies such as the increased risk of disease and increased aggression from neighbours. What causes different individuals of a particular species to take the decisions ...

New Rochelle, NY, February 25, 2014—Repeated concussions and mild brain trauma can result in reduced levels of growth hormone, gonadotropin, and thyroid hormones, causing disorders such as metabolic syndrome and erectile dysfunction and overall poor quality of life. The results of a new study of retired professional football players that compares number of concussions sustained during their careers and health problems associated with hormonal deficiency is published in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is ...

The rate of mother to child HIV transmission is at an all-time low in the UK, according to a paper published today in the journal AIDS. The study examined over 12 000 pregnancies in women diagnosed with HIV before or during pregnancy and delivered in 2000-2011; there was a four-fold drop in the rate of mother to child transmissions, from 2.1% in 2000-2001 to 0.46% in 2010-2011. Dr Claire Townsend (UCL Institute of Child Health) said: "Mother to child HIV transmission is now at the lowest level ever in the UK & Ireland, and as far as we're aware such low levels have ...

Since he was a graduate student, Armando Solar-Lezama, an associate professor in MIT's Department of Electrical Engineering and Computer Science, has been working on a programming language called Sketch, which allows programmers to simply omit some of the computational details of their code. Sketch then automatically fills in the gaps. If it's fleshed out and made more user-friendly, Sketch could ultimately make life easier for software developers. But in the meantime, it's proving its worth as the basis for other tools that exploit the mechanics of "program synthesis," ...

The sun emitted a significant solar flare, peaking at 7:49 p.m. EST on Feb. 24, 2014. NASA's Solar Dynamics Observatory, which keeps a constant watch on the sun, captured images of the event. Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may impact Earth, please ...

A study led by Manchester scientists has shown promising results for a new treatment approach in follicular lymphoma. Follicular lymphoma is a type of non-Hodgkin's lymphoma– a blood cancer - that usually develops slowly. The majority of patients are diagnosed when their disease is at an advanced stage. Recent improvements in treatment have included the use of antibodies to specifically target the tumour cells and to stimulate the patient's own immune system to attack their tumour. The use of such antibodies has improved treatment response, but unfortunately most patients ...

LOS ANGELES (Feb. 24, 2014) – Researchers at the Cedars-Sinai Maxine Dunitz Neurosurgical Institute and Department of Neurosurgery have developed a unique, compact, relatively inexpensive imaging device to "light up" malignant brain tumors and other cancers. The experimental system consists of a special camera designed and developed at Cedars-Sinai and a new, targeted imaging agent based on a synthetic version of a small protein – a peptide – found in the venom of the deathstalker scorpion. The imaging agent, Tumor Paint BLZ-100, a product of Blaze Bioscience Inc., homes ...

A real-time hurricane analysis and prediction system that effectively incorporates airborne Doppler radar information may accurately track the path, intensity and wind force in a hurricane, according to Penn State meteorologists. This system can also identify the sources of forecast uncertainty. "For this particular study aircraft-based Doppler radar information was ingested into the system," said Fuqing Zhang, professor of meteorology, Penn State. "Our predictions were comparable to or better than those made by operational global models." Zhang and Erin B. Munsell, ...

Of the top 10 cancers in the UK, bladder cancer is only one where survival rates have been shown to be getting worse. New figures published this month in the Journal of Clinical Urology confirm in a study of cases of bladder cancer in England over a 19 year period (from 1990 until 2009) that survival rates here in the UK are falling and are worse than in than in other European countries with similar incidence rates. Shockingly, bladder cancer isn't a rare cancer that only affects a few people every year. In fact, bladder cancer is our 7th most common cancer (the 4th most ...

New research shows that almost one-third of adults with mental illness are likely to be victims of violence within a six-month period, and that adults with mental illness who commit violence are most likely to do so in residential settings. The study also finds a strong correlation between being a victim of violence and committing a violent act. The work was done by researchers at North Carolina State University; RTI International; the University of California, Davis; Simon Fraser University; and Duke University. "We hear about the link between violence and mental illness ...

A belief in anti-vaccine conspiracy theories may have significant and detrimental consequences for children's health, new research from the University of Kent has shown. Researchers Daniel Jolley and Dr Karen Douglas, of the University's School of Psychology, surveyed 89 parents about their views on anti-vaccine conspiracy theories and then asked them to indicate their intention to have a fictional child vaccinated. It was found that stronger belief in anti-vaccine conspiracy theories was associated with lower intention to vaccinate. In a second study, 188 participants ...

RICHLAND, Wash. – By adjusting water discharges in ways designed to boost salmon productivity, officials at a dam in central Washington were able to more than triple the numbers of juvenile salmon downstream of the dam over a 30-year period, according to a study published Feb. 25 in the Canadian Journal of Fisheries and Aquatic Sciences. "This is one of the most productive populations of fall Chinook salmon anywhere in the Pacific Northwest," said Ryan Harnish, first author of the paper and a fish ecologist at the Department of Energy's Pacific Northwest National Laboratory. ...
