Many people do not worry about tooth decay until they are told they have a dental cavity, possibly thinking that cavities are difficult to prevent and cannot be detected until they are causing pain. However, the opposite is actually true. Cavities and tooth decay may be detected before much damage has affected the tooth, and new dental technology called DIAGNOdent is making early detection even easier than traditional cavity detection. The Dental Explorer vs. DIAGNOdent In traditional general dentistry a cavity may be detected by pressing the pointed end of a dental ...

Reducing the ability of certain bacteria to fix carbon dioxide can greatly increase their production of hydrogen gas that can be used as a biofuel. Researchers from the University of Washington, Seattle, report their findings in the current issue of online journal mBio®. "Hydrogen gas is a promising transportation fuel that can be used in hydrogen fuel cells to generate an electric current with water as the only waste product," says Caroline Harwood, who conducted the study with James McKinlay. "Phototrophic bacteria, like Rhodopseudomonas palustris obtain energy from ...

Post-sex blues is not a sexual behaviour commonly discussed, but a Queensland University of Technology (QUT) study of more than 200 young women has found one in three (32.9 per cent) had experienced the phenomenon at some point. QUT Associate Professor Robert Schweitzer's research, published in the latest International Journal of Sexual Health, looked at the prevalence of postcoital dysphoria or the experience of negative feelings following otherwise satisfactory intercourse. "While 32.9 per cent of women reported experiencing symptoms of postcoital dysphoria at least ...

What is otoplasty? Otoplasty is a plastic surgical procedure in which your ears are reshaped and reduced in size. Also known as "ear pinning," otoplasty reshapes the cartilage in your ears to give them a natural look that is more suited to the contours and size of your entire head. Can children have otoplasty surgery? Children as young as six years old can have otoplasty surgery. It is not recommended that children have otoplasty prior to this age because their ears are still developing. Teasing and name-calling can have a tremendously negative affect on your child's ...

Many myths and misconceptions abound regarding child support. Some may come from the fact that different states have different laws regarding child support; others may come from experiences people have had in the past that are no longer relevant due to changes in the law. Below are some commonly-held beliefs -- some true, some false -- about child support. Belief: There is an enormous backlog of unpaid child support. This is true. In Virginia alone, custodial parents are collectively owed $2.6 billion in past-due child support. Belief: Once child support amounts ...

A three-drug cocktail can eliminate the hepatitis C virus in patients far more effectively than the current two-drug regimen, according to researchers at Henry Ford Hospital. "This study represents a remarkable advance and a potential cure for people with hepatitis C who have not responded to previous therapy," says co-author Stuart C. Gordon, M.D., section chief for the Division of Hepatology at Henry Ford Hospital. "We will soon have a new standard of treatment for hepatitis C patients," says Dr. Gordon. "This study ushers in a new era of drug development that will ...

Researchers at the University of British Columbia and Union College (Schenectady, N.Y.) have found that people's death anxiety can influence them to support theories of intelligent design and reject evolutionary theory. Existential anxiety also prompted people to report increased liking for Michael Behe, intelligent design's main proponent, and increased disliking for evolutionary biologist Richard Dawkins The lead author is UBC Psychology Asst. Prof. Jessica Tracy with co-authors Joshua Hart, assistant professor of psychology at Union College, and UBC psychology ...

The scarf became caught in the machine and it pulled her in before stopping. There are many dangers associated with working at a dry cleaner. Chemical, fire, and ergonomic-related hazards are all risks connected to the dry cleaning processes. Dry cleaning ...

This press release is available in Spanish. Basic Yellow 1, a dye used in neuroscience laboratories around the world to detect damaged protein in Alzheimer's disease, is a wonder drug for nematode worms. In a study appearing in the March 30, online edition of Nature, the dye, also known as Thioflavin T, (ThT) extended lifespan in healthy nematode worms by more than 50 percent and slowed the disease process in worms bred to mimic aspects of Alzheimer's. The research, conducted at the Buck Institute for Research on Aging, could open new ways to intervene in aging and age-related ...

The object dominating this image may resemble a pool of spilled blood, but rather than being associated with death, such regions of ionised hydrogen -- known as HII regions -- are sites of creation with high rates of recent star birth. NGC 371 is an example of this; it is an open cluster surrounded by a nebula. The stars in open clusters all originate from the same diffuse HII region, and over time the majority of the hydrogen is used up by star formation, leaving behind a shell of hydrogen such as the one in this image, along with a cluster of hot young stars. The host ...

From President Obama's earliest days in office, he made it clear that the administration would crack down on people who had previously evaded taxes through undeclared offshore bank accounts. To encourage people with undeclared accounts to come forward voluntarily, the administration offered a limited amnesty program. Through the amnesty program, individuals with past-due taxes could disclose their unreported offshore assets and pay the back taxes while avoiding criminal charges and facing limited civil penalties. Since the announcement of the initial amnesty program, ...

Congress recently raised the lifetime gift tax exemption from $1 million to $5 million, or $10 million for married couples. This higher exemption amount provides an incentive for some people to give away their money in their lifetimes, rather than waiting until after they are gone. Not only does lifetime giving offer the emotional benefit of seeing how the money is used during the grantor's lifetime, it also enables the grantor to shift assets out of his or her estate tax-free. Increased Exemptions, Increased Ability to Shield Assets From Taxes Following a year ...

Breast cancer patients who become resistant to tamoxifen may have low levels of a protein called Rho GDI-alpha, according to a study published online March 30 in the Journal of the National Cancer Institute. Women whose tumors have estrogen receptors (ERs) often take tamoxifen after surgery to prevent recurrence of the cancer and keep it from metastasizing to other parts of the body. Some patients, however, become resistant to the drug even though their tumors remain ER-positive. To explore the mechanisms of this resistance, Suzanne Fuqua, Ph.D., professor of medicine ...

COLUMBUS, Ohio – The most recently discovered amino acid, pyrrolysine, is produced by a series of just three chemical reactions with a single precursor – the amino acid lysine, according to new research. Scientists at Ohio State University used mass spectrometry and a series of experiments to discover how cells make the amino acid, a process that until now had been unknown. They confirmed that pyrrolysine is made from enzymatic reactions with two lysine molecules – a surprising finding, given that some portions of its structure suggested to researchers that it might ...

While recent years have presented many challenges for Americans, one news item from last year was welcome: no fatal U.S. airline crashes occurred in 2010. Over the past two decades, the National Transportation Safety Board's statistics for major commercial aircraft accidents involving fatalities show a steady decrease from the early 1990s, despite a 50 percent increase in aircraft hours flown. Aviation accident fatalities have never been worse than one per 15 million passengers since the devastating year of 2001. U.S. airlines have also recorded zero fatalities in three ...

An experimental drug lessens symptoms of a rare form of childhood leukemia and offers significant insight into the cellular development of the disease, according to findings from a new UCSF study. The mouse model research could spearhead the development of new leukemia therapies and paves the way for future clinical trials in humans. "Although this drug did not produce a cure, it alleviated the symptoms of leukemia as long as the treatment was continued and delayed the development of a more aggressive disease," said senior author Benjamin Braun, MD, PhD, a pediatric ...

Research from Royal Holloway, University of London and the University of Bristol calls into question people's ability to form their own judgements about their preferred election candidate after finding voters could be heavily swayed by 'the worm' - a continuous response tracking measure this is increasingly being used in live election debates around the world. The study "Social Influence in Televised Election Debates: A Potential Distortion of Democracy" is published today (30 March) in the journal PLoS One. Televised election debates were introduced in the United ...

On January 20, Chester Lee Mills Sr. was supposed to bury his wife, who had lost her battle with lung cancer. Instead, Mills was left to mourn the additional loss of his two children who died in a tragic truck accident en route to their stepmother's funeral. Amanda S. Mills, age 25; Logan R. Mills, age 21; and Anthony Suggs, age 25, were travelling to Georgia to attend the funeral when they were hit by a semi-truck after losing control of their car on icy roads. Witnesses said that the tractor-trailer turned over onto the passenger vehicle, pinning the three people in the ...

LA JOLLA, CA – March 30, 2011 – If, as Shakespeare's Juliet declared, a rose by any other name smells as sweet – to you and to me and to anyone else who sniffs it – then one might assume that our odor-sensing nerve cells are all wired in the same way. Alas, they are not, according to a new study from scientists at The Scripps Research Institute. The researchers developed a new virus-based technique for highlighting individual nerve pathways, then applied it to the olfactory systems of mice. They found that mouse olfactory neurons send signals to two key processing regions ...

Everyone would like MDs to have the best education – and to absorb what they are taught. The lead article in the April 4 issue of the journal Academic Medicine* connects research on how the brain learns to how to incorporate this understanding into real world education, particularly the education of doctors. "Repetition, reward, and visualization are tried and true teaching strategies. Now, knowing what is happening in the brain will enhance teaching and learning," said Michael J. Friedlander, executive director of the Virginia Tech Carilion Research Institute (www.vtc.vt.edu/research/index.html) ...

A California Court of Appeals case highlights why it is important for business owners to understand their company's insurance policy, especially the exclusions. A Case in Point In 2004, Terrell Ford was dining at a restaurant owned by Palmden. During this time, 20 gang members entered the restaurant and caused a disturbance. Shortly thereafter, the argument was brought outside and a fight instigated. Ford attempted to leave, but the restaurant employees locked the front doors so he exited a back door. He was attacked and severely beaten by gang members and suffered ...

According to the National Highway Traffic Safety Administration, more than 6 million motorcycles are registered in the U.S., which is about 3 percent of all registered vehicles in the country. However, motorcyclists are seriously injured and killed at a much higher rate than their 4-wheeled counterparts, as 11 percent of all highway deaths each year are motorcycle fatalities. A variety of factors contribute to the high number of motorcycle crashes each year, including: - Inexperienced riders - Insufficient training - Dangerous road conditions - Low visibility to ...
