New research out of the Kimmel Cancer Center at Thomas Jefferson University has found that Wikipedia’s information on cancer is considerably accurate. The center analyzed Wikipedia’s content on ten different types of cancer and compared it to the information provided by the National Cancer Institute’s Physician Data Query, a professional database that is peer reviewed and edited. The site was also compared to information provided by textbooks.
The study found that Wikipedia’s information was solid and reliable, especially when it came to the key points. Only two percent of the information did not match up to textbooks. However, the information was also determined to be very dense and written at a high level of complexity, making it more difficult to read and comprehend.
New research conducted by the University of Copenhagen has found that midnight snacking is associated with a greater risk of tooth loss. The main cause is the change in the flow of saliva, which decreases at night. Saliva is essential in removing food particles from the mouth.
Out of the 2,217 participants, 8 percent were classified as nocturnal eaters. Over a period of six years, these nocturnal eaters ended up losing more teeth, even after controlling for other significant factors, such as age, smoking, and sugar consumption.
Researchers out of Bristol University in England have found that caffeine drinkers develop a tolerance to its stimulating effects. The findings indicate that even though coffee drinkers may feel more alert after their morning dose of caffeine, the beverage only brings caffeine addicts back to the baseline level of alertness, rather than allowing them to exceed it.
New research shows that young adults in romantic relationships are less likely to abuse drugs or alcohol, the LA Times reports. The study consisted of 909 participants, followed from first grade through the age of 19 or 20. Those not in a stable relationship at this age were about 40 percent more likely to abuse drugs and alcohol than those who were in a stable relationship, even when controlling for other factors that affect substance abuse.
The researchers believe that perhaps young people in relationships are spending less time with friends who may have substance abuse problems. Another thought is that those in a relationship receive support from their significant other that helps them avoid destructive behavior.
