In one week from today, the Large Hadron Collider(LHC) will take its first step 'back in time.' What is mass? What happened at the beginning of the universe? Are there other dimensions? We'll be on the way to finding out.
It's taken about 6,000 researchers, been over budget and behind schedule but it's finally ready to go.
If all goes according to plan, the superconducting magnets in the collider will zap atomic particles around the 17-mile tunnel at roughly the speed of light. Then the scientists will smash the particles together, replicating what happened mere nanoseconds after the first big bang.
We can keep suicidal individuals from committing suicide successfully by making sure they can't get a gun, say researchers at Harvard School of Public Health.
The article in The New England Journal of Medicine (NEJM) was written by Matthew Miller, assistant professor of health policy and management ans associate director of the Harvard Injury Control Research Center, and David Hemenway, professor of health policy and director of the Harvard Injury Control Research Center.
Suicide is the second-leading cause of death among Americans 40 years old and younger, according to their statistics. Among Americans of all ages, more than half of all completed suicides are gun suicides. Additionally, an estimated one-third to four-fifths of all suicide attempts, according to studies, are impulsive--with 24% taking less than 5 minutes between the decision to kill themselves and the actual attempt, while 70% took less than 1 hour.
Mice given quercetin, a naturally occurring substance found in fruits and vegetables, were less likely to contract the flu, according to a study published by The American Physiological Society. The study also found that stressful exercise increased the susceptibility of mice to the flu, but quercetin canceled out that negative effect.
Quercetin, a close chemical relative of resveratrol, is present in a variety of fruits and vegetables, including red onions, grapes, blueberries, tea, broccoli and red wine. It has been shown to have anti-viral properties in cell culture experiments and some animal studies, but none of these studies has looked specifically at the flu.
Although this study was done with mice, a recent human study found that people who took quercetin suffered fewer illnesses following three days of exhaustive exercise compared to those who did not. Unlike the mouse study, the humans were not inoculated with a virus.
Today there is rapidly growing interest in 'intelligent' computer-based methods that use various classes of measurement signals, from different patient samples, for instance, to create a model for classifying new observations. This type of method is the basis for many technical applications, such as recognition of human speech, images, and fingerprints, and is now also beginning to attract new fields such as health care.
These 'intelligent' computer-based methods for classifying patient samples have been evaluated by Swedish researchers at Uppsala University with the help of two methods that have completely dominated research for 25 years; cross validation and resampling/bootstrapping.
Their conclusion; they're worthless for practical problems.
According to the Center for Disease Control (CDC), osteoarthritis, the most common type of arthritis, is on the rise. A new study published in the August journal of Phytotherapy Research, says that Pycnogenol, bark extract from the French maritime pine tree, reduced overall knee osteoarthritis (OA) symptoms by 20.9 percent and lowered pain by 40.3 percent. To date, this is the third clinical trial on osteoarthritis treatment with Pycnogenol.
This study investigated what happens to joint symptoms after treatment with Pycnogenol is terminated and the results show that no relapse occurred after two weeks. Pycnogenol acts as an anti-inflammatory and the effects found in this study suggest that Pycnogenol may help the joints to recover.
A new study published online today in the British Journal of Nutrition found that timing of dietary protein intake affects feelings of fullness throughout the day. The study concluded that when people ate high-quality protein foods, from sources such as eggs and lean Canadian bacon, for breakfast they had a greater sense of sustained fullness throughout the day compared to when more protein was eaten at lunch or dinner.i
"There is a growing body of research which supports eating high-quality protein foods when dieting to maintain a sense of fullness," said Wayne W. Campbell, PhD, study author and professor of Foods and Nutrition at Purdue University. "This study is particularly unique in that it looked at the timing of protein intake and reveals that when you consume more protein may be a critical piece of the equation."
