Premature tooth loss can affect oral health for years to come
The prospect of exchanging a tooth for that coveted reward from the tooth fairy often has kids wiggling teeth with vigor, but what happens when a primary or permanent tooth is lost prematurely due to trauma?

Major 'missed' biochemical pathway emerges as important in virtually all cells
A new study by Duke University researchers provides more evidence that the nitric oxide (NO) system in the life of a cell plays a key role in disease, and the findings point to ways to improve treatment of illnesses such as heart disease and cancer.

Hubble, Keck images show continued turbulence in Jupiter's atmosphere
Increased turbulence and storms first observed on Jupiter more than two years ago are still raging, according to astronomers from the University of California, Berkeley, and the W. M. Keck Observatory in Hawaii, who snapped high-resolution pictures of the planet earlier this month.

Study identifies food-related clock in the brain
In investigating the intricacies of the body's biological rhythms, scientists at Beth Israel Deaconess Medical Center (BIDMC) have discovered the existence of a "food-related clock" which can supersede the "light-based" master clock that serves as the body's primary timekeeper.

A trial of removing food additives should be considered for hyperactive children
A properly supervised trial eliminating colours and preservatives from the diet of hyperactive children should considered a part of the standard treatment, says an editorial in this week's BMJ.

Researchers explore the emerging role of infection in Alzheimer's disease
A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis.

Phoenix mission to Mars will search for climate clues
On May 25, 2008, approaching 5 p.m. PDT, NASA scientists will be wondering: Just how green is their valley? That's because at that time the Phoenix Mars Mission space vehicle will be touching down on its three legs to make a soft landing onto the northern Mars terrain called Green Valley.

More patients with drug-coated cardiac stents survive, avoid costly follow-up procedures
The more than ten million Americans who've received drug-eluting stents to open their blocked coronary arteries have a bright future, according to new research from the University of Pennsylvania School of Medicine.

First of its kind study compares high school knee injuries by sport and gender
Knee injuries, among the most economically costly sports injuries, are the leading cause of high school sports-related surgeries according to a study conducted at the Center for Injury Research and Policy (CIRP) of the Research Institute at Nationwide Children's Hospital and published in the June issue of The American Journal of Sports Medicine.

New research: Fruit juice consumption not related to overweight in children
Despite studies that assert otherwise, 100% fruit juice consumption is not related to overweight in children, according to the authors of "A Review of the Relationship Between 100% Fruit Juice Consumption and Weight in Children and Adolescents" in the May/June issue of the American Journal of Lifestyle Medicine (AJLM), published by SAGE.

Nitrogen retained through loss
The nitrogen cycle plays a major role in seagrass fields. Dutch researcher Arie Vonk studied the nitrogen dynamics of seagrasses in Indonesia. He discovered that the interaction between seagrasses, animals and microorganisms results in an efficient nitrogen cycle in tropical seagrass fields. Consequently the nitrogen lost from seagrasses is still retained.

At the synapse: Gene may shed light on neurological disorders
In our brains, where millions of signals move across a network of neurons like runners in a relay race, all the critical baton passes take place at synapses.

Scientists reveal the lifestyle evolution of wild marine bacteria
Marine bacteria in the wild organize into professions or lifestyle groups that partition many resources rather than competing for them, so that microbes with one lifestyle, such as free-floating cells, flourish in proximity with closely related microbes that may spend life attached to zooplankton or algae.

Oocyte-specific gene mutations cause premature ovarian failure
Mutations in a gene called FIGLA cause premature ovarian failure in at least a percentage of women who suffer from the disorder, said researchers from Baylor College of Medicine in Houston and Shandong University in China in a report that appears online today in the American Journal of Human Genetics.

Miracle leaves that may help protect against liver damage
Sea buckthorn (Hippophae rhamnoides) berries are well known for their cholesterol busting properties, but scientists in India say that its leaves are also rich in anti-oxidants and may help ward off liver disease, according to new research due to be published in the Society of Chemical Industry's (SCI) Journal of the Science of Food and Agriculture.

Stabilizing cancer-fighting p53 can also shield a metastasis-promoter
Efforts to protect the tumor-suppressor p53 could just as easily shelter a mutant version of the protein, causing cancer cells to thrive and spread rather than die, according to research by scientists at The University of Texas M. D. Anderson Cancer Center reported in the current issue of the journal Genes and Development.

Reducing Blockage Fails to Improve Access to the Bloodstream for Kidney Dialysis
Reducing early blockages in bloodstream access for kidney failure treatment does not increase the likelihood that the access will function adequately for long-term treatments, according to a study funded by the National Institutes of Health. Results were published May 14, 2008, in the Journal of the American Medical Association.

Will polyclinics deliver real benefits to patients?
Government proposals to establish polyclinics are intended to reshape NHS services, but will they deliver the more patient centred care they propose, or do they risk becoming an expensive mistake"
