A cap that literally cools the brain during sleep may be an effective insomnia treatment, according to new research.
The American Academy of Sleep Medicine says that chronic insomnia, symptoms that last for at least a month, affects about 10 percent of adults. Most often insomnia is a "comorbid" disorder, occurring with another medical illness, mental disorder or sleep disorder, or associated with certain medications or substances. Fewer people with insomnia are considered to have primary insomnia, which is defined as a difficulty falling asleep or maintaining sleep in the absence of coexisting conditions.
Baseball coaches often use traditional metrics for managerial decisions, like batting results against specific pitchers, performance in certain park configurations and whether they bat from the left or right side in making strategic lineup decisions.
Maybe some day they can also think about what 'sleep type' their players are.
If you're in an older generation and a female calls another female "dude", it may seem strange to you. It happens all of the time and should be a sign that sexism is less today but a recent study from Psychology of Women Quarterly says subtle, unnoticed daily acts of sexism like that, even women doing it to women, are a concern.
A new study offers insights about the interaction between a toxic protein called progerin and telomeres, which cap the ends of chromosomes like aglets, the plastic tips that bind the ends of shoelaces.
Telomeres wear away during cell division. When they degrade sufficiently, the cell stops dividing and dies. The researchers have found that short or dysfunctional telomeres activate production of progerin, which is associated with age-related cell damage. As the telomeres shorten, the cell produces more progerin.
Progerin is a mutated version of a normal cellular protein called lamin A, which is encoded by the normal LMNA gene. Lamin A helps to maintain the normal structure of a cell's nucleus, the cellular repository of genetic information.
The American Academy of Pediatrics recently recommended that screening for autism be incorporated into routine
physician check-ups, even if no concern has been raised by the parents.
Such routine screening of all children for autism gets a thumbs down from researchers at McMaster University in a Pediatrics study. The researchers say there is "not enough sound evidence to support the implementation of a routine population-based screening program for autism."
Everyone is a journalist due to the modern Internet, we are told. Not so, says a University of Georgia analysis. Instead, 2 percent of people who start discussions attract about 50 percent of the replies and that is good news for traditional journalism.
The downside is they used Internet newsgroups to validate this belief - if you aren't familiar with newsgroups, that's because Web-based interfaces killed their popularity but throughout much of the 1990s newsgroups were popular and even Google makes the newsgroup interface more attractive.
