Ultra-Useful Ultrasound Causing A Stir In Materials Science
As the molecules are manipulated by the sound wave, tiny cavities are formed and destroyed inside the material that release high levels of energy when they implode, causing chemical or physical reactions to occur. Sonochemistry is already proving a useful tool and is being applied commercially in the former Soviet Union in the casting process and... view more... (1999-02-03)
Revamped experiment could detect elusive particle, physicists say
An experiment called "shining light through walls" would seem hard to improve upon. But University of Florida physicists have proposed a way to do just that, a step they say considerably improves the chance of detecting one of the universe's most elusive particles, a candidate for the common but mysterious dark matter. view more (2007-04-26)
Micro honeycomb materials enable new physics in aicraft sound reduction
Noise from commercial and military jet aircraft causes environmental problems for communities near airports, obliging airplanes to follow often complex noise-abatement procedures on takeoff and landing. It can also make aircraft interiors excessively loud. view more (2008-09-30)
Filming an ultra-fast biological reaction essential to life
A team of scientists from the USA in collaboration with staff at the European Synchrotron Radiation Facility1 (Schotte et al) have managed to film a protein at work in unprecedented detail. The protein is the oxygen-storing molecule myoglobin, which plays a central role in the production of energy in muscles. The motion of the protein was recorded... view more... (2003-06-24)
New stem cell research unlocks unknown therapies
"Stem cell research and regenerative medicine are in an extremely exciting phase right now. We are gaining knowledge very fast and many companies are being formed and are starting clinical trials in different areas," says Dr Jonas Frisén. view more (2009-05-22)
Ice has a starring role - CMD19/CMMP with The Physics Congress 2002
When even moderately hot stars like our Sun have surface temperatures of around 6,000°C, it is hard to imagine that ice plays an important part in their formation. But that`s exactly what astrophysicists have recently discovered by turning to surface scientists for help. At the Condensed Matter conference on Monday 8 April, part of the... view more...

Fluoride varnish helps prevent tooth decay in very young children
Fluoride varnish, a dental preventive treatment, reduces the incidence of early childhood tooth decay in combination with dental health counseling for parents. view more (2006-01-30)
Sponges recycle carbon to give life to coral reefs
Coral reefs support some of the most diverse ecosystems on the planet, yet they thrive in a marine desert. So how do reefs sustain their thriving populations? view more (2009-11-13)
Duke study examines evolutionary consequences of bluebird aggression
In findings that may offer insight into how evolution operates, a Duke University evolutionary ecologist reported evidence that aggressive male western bluebirds out-compete less aggressive males for preferred breeding territories. view more (2006-04-13)
Cigarette smoking nearly doubles risk for root canal treatment
According to a new study appearing in the April issue of the Journal of Dental Research, cigarette smoking can lead to not only tooth discoloration and gum disease, but also a common dental procedure that helps to heal a diseased tooth-the root canal. view more (2006-02-24)
Open wide and say 'zap'
A group of researchers in Australia and Taiwan has developed a new way to analyze the health of human teeth using lasers. view more (2009-08-19)
New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)
Researchers present Phase 2 clinical results for Acologix AC-100
Today, researchers from Acologix (Hayward, CA, USA), the University of California (San Francisco, USA), and the University of Connecticut (Simsbury, USA) will announce the results of a Phase 2 clinical trial of AC-100 (also known as Dentonin), reporting that it met its primary goal of stimulating the formation of new dentin when applied directly... view more...

Topical oral syrup prevents early childhood caries
Dental researchers at the University of Washington have reported a significant reduction of tooth decay in toddlers who were treated with the topical syrup xylitol, a naturally occurring non-cavity-causing sweetener. view more (2008-07-07)
Nano-sediment highways in catalyst
Dutch chemists have visualised how the porous structure of a zeolite catalyst depends on the production method. Zeolite made with carbon fibres as a template, has particles with straight canals that act as highways for the oil components which must be converted into benzene components. Zeolite is normally given a steam treatment to improve its... view more... (2003-03-21)
Essential dental treatment safe for pregnant women, says ADA journal study

Safer Surgery wins Silver Medal for Leeds Engineer
Stuart Moran, one of the founders of Surgical Innovations, a small company based in Leeds, has won a prestigious Royal Academy of Engineering Silver Medal for his development of innovative, safe and efficient surgical laparoscopic devices. Stuart, who was promoted to the Group Board as Technical Director and Joint Managing Director of the... view more... (2004-06-10)
Studies evaluate health effects of dental amalgam in children
Scientists supported by the National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health, report in this week's Journal of the American Medical Association the results of the first-ever randomized clinical trials to evaluate the safety of placing amalgam fillings, which contain mercury, in the teeth of... view more...

Thin films of silicon nanoparticles roll into flexible nanotubes
By depositing nanoparticles onto a charged surface, researchers at the University of Illinois at Urbana-Champaign have crafted nanotubes from silicon that are flexible and nearly as soft as rubber. view more (2005-06-15)
A reason to smile: New immigrants respond best to oral hygiene campaign
Tapping into the desire to have an attractive smile is the best motivator for improving oral hygiene, and new immigrants are the most receptive to oral health messages, according to a new study in the Journal of Consumer Research. view more (2008-08-25)
