Timing Improves Cleft Palate Surgery
New research is changing the way cleft palate surgeries are performed throughout North America and around the world. Surgical timing has been a controversial topic with various cleft centers around the world opting for early closure at about 3-6 months of age. However, research complied over the past 20 years has shown that the best time to close the cleft at the alveolus (gum) in patients with either one or two sided clefts is at eight or nine years of age prior to canine tooth eruption.

Asthma Linked To Higher Suicidal Thoughts With Attempts
Asthma is associated with higher suicidal thoughts with attempted suicide, but does not seem to be linked with suicidal thoughts without attempts, according to a new report in the Annals of Allergy, Asthma & Immunology. Cigarette smoking and concurrent mental health conditions may independently account for significant proportions (but not all) of the association between asthma and suicidal thoughts with attempts noted researchers.

A Molecular Thermometer For The Distant Universe
For the first time, astronomers have detected in the ultraviolet the carbon monoxide molecule in a galaxy located almost 11 billion light-years away, a feat that had remained elusive for 25 years. This detection allows them to obtain the most precise measurement of the cosmic temperature at such a remote epoch.

New Technique Measures Ultrashort Laser Pulses At Focus
Lasers that emit ultrashort pulses of light are used for numerous applications, but the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. Researchers have developed a system that tells researchers what types of aberrations are present, which allows them to create the desired pulse at the focus that's free of distortions.

New Theory Suggests How Hepatitis C May Cause Rare Immune Disease
Of the hepatitis alphabet, the C variant may be the nastiest. In 1990, researchers observed that most patients with hepatitis C also develop a rare autoimmune disease called mixed cryoglobulinemia, a condition that frequently leads to cancer, arthritis or both. Now, researchers say that a decade-old explanation of how one disease causes the other is likely wrong, and instead offer a new -- albeit controversial -- theory of their own: that the pathogen causing the disease zeros in on a specific cellular target that has yet to be identified.

Invasion Of The Spiny Water Fleas: Drying Anchor Lines Can Help Contain Spread
Reducing the spread of some invasive species into our lakes could be as simple as asking boaters and fishers to dry out their equipment, says one biology professor studying invasive species in Lake Ontario. When anchor rope, fishing line and the boats themselves are thoroughly dried, the invasive species and their eggs will die, rather than spreading to another location, she explains. "It's such a simple thing for the general public to do, and yet it could make a big difference in the way that our lake ecosystems function."

High Blood Pressure, High Cholesterol May Be Associated With Retinal Vascular Disease
High blood pressure and high cholesterol levels appear to be risk factors for retinal vein occlusion, a condition that causes vision loss, according to a new article. Retinal vein occlusion occurs when one or more veins carrying blood from the eye to the heart become blocked, according to background information in the article. Bleeding (hemorrhage) or fluid buildup (edema) may follow, damaging vision.

Beyond Fashion: Why You Gotta Wear Shades
Cheap sunglasses may cost you less, but are they just as likely to protect against the effects of harmful UV rays as expensive sunglasses? According to the chair of ophthalmology at NewYork-Presbyterian Hospital there is no certain way for consumers to be sure they are getting ultraviolet or UV protection from their sunglasses -- even if they are labeled "UV absorbing" or "UV blocking." Cost is no indicator of UV protection. An expensive pair of sunglasses does not guarantee sufficient protection from the sun. Sunglasses are not just a fashion statement; their lenses block harmful UV rays that, in severe cases, can cause permanent damage to the eyes in the form of cataracts, pterygium and possibly retinal degeneration.

Gene Function In Regulating Body Size Helps Inform Novel Cancer Treatments
In a leading study that has implications for the development of novel therapies for a number of breast, lung and ovarian cancers that have lost the expression of a gene called glypican-3, researchers have discovered how the loss of the GPC3 gene induces overgrowth through certain growth factors such as Sonic Hedgehog which stimulate cancer growth.
