Public health researchers seeking to determine an individual's risk of developing cardiovascular disease (CVD), coronary heart disease (CHD), or stroke have previously relied on national US data, such as that provided by the National Health and Nutrition Examination Surveys (NHANES). Now, new data compiled and evaluated by researchers at the Centers for Disease Control and Prevention (CDC) provide information at the state level for the first time, paving the way for targeted intervention programs.
Physicists have devised a theoretical model to tune the conductivity of graphene zigzag nanoribbons using ultra-short pulses. Physicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. To date, the majority of graphene studies have considered the dependency of transport properties on the characteristics of the external pulses, such as field strength, period or frequency.
A surgical team in Toronto has successfully implanted a novel mechanical device, the HeartMate IIITM, into a patient with advanced heart failure. This is the first time this procedure has been conducted on Canadian soil.
Conservationists are rejoicing at the listing of 21 species of sharks and rays under the Appendices of the Convention on Migratory Species, made official today in the final plenary session of the Conference of Parties (CoP).
Combination therapy offers quicker, less toxic eradication of hepatitis C in liver transplant patients
All patients with hepatitis C who receive a liver transplant will eventually infect their new livers. These transplanted organs then require anti-viral treatment before they become severely damaged. But traditional post-transplant hepatitis C therapy can take up to a year, is potentially toxic and can lead to organ rejection. Now researchers report that use of two new oral medications post-transplant is safe and beneficial, and requires only 12 weeks of treatment.
The first steps in the origin of pancreatic cancer have been identified by researchers who say that their findings suggest preventive strategies to explore. The scientists described the molecular steps necessary for acinar cells in the pancreas -- the cells that release digestive enzymes -- to become precancerous lesions. Some of these lesions can then morph into cancer.
A newly identified signaling pathway that stimulates glucose uptake in brown fat cells might be useful for treating type 2 diabetes and obesity.
Energy use in buildings accounts for nearly two-thirds of the greenhouse gas emissions generated in Detroit, while exhaust from cars, trucks and buses is responsible for about 30 percent of the total, according to a new citywide inventory compiled by student researchers.
A new study confirms that moderate alcohol consumption can protect against coronary heart disease. But only for the 15% of the population that have a particular genotype.
An international group of researchers has discovered the first 'lighting' from a black hole, with variations in brilliance more powerful than ever observed in an extragalactic object. The emission, the researchers suggest in their study, "is associated with pulsar-like particle acceleration by the electric field across a magnetospheric gap at the base of the radio jet."
Botanists have compiled and shared 48 years' worth of global plant data to help answer some of the most pressing environmental and evolutionary questions facing modern society. People invested in living plant collections in botanic gardens through the centuries to bring economic, medicinal and agricultural advantages of plants to people all over the world. The botanists' database is moving this gift into the digital age of 'Big Data'.
Physicians play critical role in ensuring bladder cancer patients understand link between smoking, their disease
When bladder cancer patients are well-informed by their physicians, they acknowledge that tobacco use was likely the cause of their disease. At least half of bladder cancer cases diagnosed in the United States are the result of cigarette smoking. Bladder cancer is the second most common tobacco-related malignancy, a fact that is not well known even among bladder cancer surgeons, let alone the general public.
The new MUSE instrument on ESO’s Very Large Telescope has provided researchers with the best view yet of a spectacular cosmic crash. The new observations reveal for the first time the motion of gas as it is ripped out of the galaxy ESO 137-001 as it ploughs at high speed into a vast galaxy cluster. The results are the key to the solution of a long-standing mystery — why star formation switches off in galaxy clusters.
A bat species thought to be restricted to temperate forests has been found living thousands of miles from its known range in the sweltering heat of the southern Indian rainforest.
Unique Roman relief discovered: Depiction of unknown god in Turkey; Relics from 2,000 years of cult history excavated
A bearded deity has been discovered with astral symbols. Archaeologists excavated the unique Roman relief depicting an unknown god in an ancient sanctuary in Turkey. According to a first assessment, the one and a half meter (five foot) high basalt stele which was used as a buttress in the wall of a monastery shows a fertility or vegetation god, as classical scholar and excavation director said.
Recognizing the emotions other people feel is crucial for establishing proper interpersonal relations. To do so, we look at (amongst other things) facial expressions and body posture. Unfortunately, in some neurological disorders this ability is heavily impaired. This happens, for example, in multiple sclerosis where scientific evidence shows that people affected by the disease often have trouble recognizing expressions that communicate emotions. A new study now demonstrates that the same difficulty may also be encountered with emotions conveyed by posture.
The same climatic drivers that enhance upwelling of nutrient-rich ocean waters and support of marine productivity can result in lower precipitation on land and slower tree-growth. Tree-ring chronologies helped to explain how upwelling was happening during the past 600 years.
A new drug combination for rheumatoid arthritis treats the disease just as well as other intensive treatment strategies but with less medication and fewer side effects at a significantly lower cost.
Male crustaceans can ‘lock down’ their maleness to avoid being completely feminized by seawater contaminated by feminizing pollutants, according to scientists.
Research scientists have demonstrated a new technique for generating electrical energy. The new method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed, for example, in wireless self-powered sensors and medical implants, where they could ultimately replace batteries. In the future, energy harvesters can open up new opportunities in many application areas such as wearable electronics.
