The best efforts of dentists don’t always mean people will look after their teeth, British researchers have found.
A study by a team at the University of Newcastle upon Tyne discovered that only up to one-third of gum disease patients, who received advice on how long to brush their teeth, followed it to the letter. Yet the same people perceived their brushing habits to be better than they were – a finding which has major implications for dentists wishing to change their patients’ behaviour.
Gum disease can eventually lead to multiple tooth loss, but in many cases damage can be stabilised or reversed if treatment is combined with a good home toothcare regime. For the study, patients were given advice on a regime – which in particular said they should brush their teeth twice a day for two minutes each time. Each of the 17 study participants used an electronic ‘data logger’ powered toothbrush that recorded brushing time. The brush had a light on the handle that flashed when two minutes had elapsed. They were also asked to fill in diaries detailing their brushing habits. The experiment recorded brushing times for two periods of four weeks.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
