Thousands of children with oral pain are being taken by parents to pharmacies and non-dental health services, including A&E, instead of their dentist, and could be costing NHS England £2.3 million a year, according to research led by Queen Mary University of London.
The study of more than half of all of the pharmacies in London and nearly 7,000 parents finds that most pharmacy visits for children's pain medications in London are to treat oral pain.
Warm, wet summers are historically unusual and could bring unexpected disruptions to ecosystems and society, according to new research from the University of British Columbia.
As climate change raises summer temperatures around the world, increases in precipitation could offset drought risk in some regions. However, a paper published in Nature Communications this month shows that wetter summers may bring other problems in a warming climate.
People who are easily disgusted by body odours are also drawn to authoritarian political leaders. A survey showed a strong connection between supporting a society led by a despotic leader and being sensitive to body odours like sweat or urine. It might come from a deep-seated instinct to avoid infectious diseases. 'There was a solid connection between how strongly someone was disgusted by smells and their desire to have a dictator-like leader who can supress radical protest movements and ensure that different groups "stay in their places".
An international team of researchers has developed a computational resource that provides a 3D view of genes, proteins and metabolites involved in human metabolism. Researchers used the tool to map disease-related mutations on proteins and also probed how genes and proteins change in response to certain drugs. The work provides a better understanding of disease-causing mutations and could enable researchers to discover new uses for existing drug treatments.
Children as young as seven apply basic laws of physics to problem-solving, rather than learning from what has previously been rewarded, suggests new research from the University of Cambridge.
The findings of the study, based on the Aesop's fable The Crow and the Pitcher, help solve a debate about whether children learning to use tools are genuinely learning about physical causation or are just driven by what action previously led to a treat.
Munich based Laser physicists have developed an extremely powerful broadband infrared light source. This light source opens up a whole new range of opportunities in medicine, life science, and material analysis.
Jupiter's icy moon Europa is a major target of astrobiology research in light of the possibility that it offers a habitable environment in the Solar System. Under its ice crust, estimated to be 10 km thick, is an ocean of liquid water of over 100 km deep. A huge source of energy deriving from gravitational interaction with Jupiter keeps this water warm.
Optical waves propagating away from a point source typically exhibit circular (convex) wavefronts. "Like waves on a water surface when a stone is dropped", explains Peining Li, EU Marie Sklodowska-Curie fellow at nanoGUNE and first author of the paper. The reason of this circular propagation is that the medium through which light travels is typically homogenous and isotropic i.e. uniform in all directions.
It is one of the most astonishing results of physics: when a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles, for example, chaotically swirling around in a container, will return almost exactly to their starting positions after some time. This "Poincaré Recurrence Theorem" is the foundation of modern chaos theory. For decades, scientists have investigated how this theorem can be applied to the world of quantum physics.
A new technique developed by neuroscientists at the University of Toronto Scarborough can, for the first time, reconstruct images of what people perceive based on their brain activity gathered by EEG.
The technique developed by Dan Nemrodov, a postdoctoral fellow in Assistant Professor Adrian Nestor's lab at U of T Scarborough, is able to digitally reconstruct images seen by test subjects based on electroencephalography (EEG) data.
A UCLA study explored the relationship between new drivers' skills and four factors. Instructors from a Los Angeles driving school rated students' driving skills on a scale of 1 to 4, and the researchers analyzed the results based on these variables:
Age: Among males, the older the student, the worse his driving skills score. Male teens scored 36 percent higher on driving skills than men in their 20s. The same pattern did not hold true for women.
Washington DC, Feb. 22 - A study published today in Science illuminates the extent of global fishing - down to individual vessel movements and hourly activity - and opens an unprecedented gateway for improved ocean management. The study shows that, while the footprint of capture fishing extends across more than half the global ocean, activity is clearly bounded by different management regimes, indicating the role well-enforced policy can play in curbing over-exploitation.
In a large ethnically diverse group of patients seen at a community-based Veterans Affairs practice, cure rates for chronic hepatitis C were lower for African American individuals relative to White individuals, even when patients were receiving optimal therapies. The findings are published in Pharmacology Research & Perspectives.
There is substantial international variation in mortality rates after treatment for abdominal aortic aneurysm, or enlargement of the aorta. A BJS (British Journal of Surgery) study that compared 10-year data from England and Sweden found that mortality rates were initially better in Sweden but improved over time alongside greater use of a minimally invasive procedure called endovascular aneurysm repair in England.
CHAMPAIGN, Ill. -- Iron deficiency in the first four weeks of a piglet's life - equivalent to roughly four months in a human infant - impairs the development of key brain structures, scientists report. The abnormalities remain even after weeks of iron supplementation begun later in life, the researchers found.
