Successful aging and positive quality of life indicators correlate with sexual satisfaction in older women, according to a report in the Journal of the American Geriatric Society which also shows that self-rated 'successful' aging, quality of life and sexual satisfaction appear to be stable even in the face of declines in physical health of women between the ages of 60 and 89.
The study used 1,235 women enrolled at the San Diego site of the Women's Health Initiative (WHI) study, an ongoing program funded by the National Institutes of Health which has addressed causes of death, disability and quality of life in more than 160,000 generally healthy, post-menopausal women since 1993.
The authors of a new study in Nature Neuroscience studied mechanisms used by the brain to store information for a short period of time. The cells of several neural circuits store information by maintaining a persistent level of activity; a short-lived stimulus triggers the activity of neurons, and this activity is then maintained for several seconds. The mechanisms of this information storage phenomenon occurs in very many areas of the brain.
There's long been a maddening belief by a subset of psychologists who have never actually been to the Eastern part of the world that Asia is some collectivist Utopia.
When it comes to inflated self-importance - hubris, even - some research contends, there is more of it in the west because Western culture prides itself on independence, personal success and uniqueness while in the East where harmony and belonging are supposedly valued, people are more modest.
How many organisms live on this little planet of ours? A pretty straight-forward question. The answer, however, is much more enigmatic. Estimates range from a careful 3 million to a huge 100 million. Now, a new approach, published in PLoS Biology, has yielded another estimate. The new method used resulted in an estimate of 8.7 million (± 1.3 million SE) eukaryotic species, of which 2.2 million (± 0.18 million SE) can be found in the oceans. As about 1.2 million species are catalogued, this would mean that roughly 86% of organisms on earth still await discovery, a number that rises to 91% in the oceans.
Where do these numbers come from?
Cardiovascular diseases (CVD) already account for one third of all global deaths and raising, with effective heart regeneration therapies yet to be developed despite worldwide research efforts. But a new study by scientists from Oxford University and the University of Coimbra in Portugal might have put us a step closer with the discovery of the key molecule regulating the development of several heart and blood vessels’ tissues in the zebrafish embryo.
Complexity theorists have some bad news for people who insist that unless it carries an organic label, food is evil; a group from the New England Complex Systems Institute says they've discovered what will trigger riots around the world in under two years. It's the price of food and when it rises above the threshold they list for instability, social unrest will sweep the planet.
Cooking is not a modern invention, concludes new research. It likely originated 1.9 million years ago, according to results they determined using statistical analysis and evolutionary trees.
How so? They estimated, in their analysis, how long we should spend feeding every day, based on our body sizes throughout evolutionary history. Sure, it might seem at first glance like cooking would add more time than directly eating but their results say we would need to spend almost half of our time in the 'feeding' process given our current sizes - cooking basically made food easier to chew and digest and as a result we got more caloric benefit and a smaller digestive tract.
Pseudomonas aeruginosa (see figure 1) is a human pathogen that colonizes the respiratory and gastrointestinal tract, where it can cause life-threatening infections in patients with a compromised immune system, such as cancer or cystic fibrosis patients. P. aeruginosa is resistant to many antibiotics. Current treatments comprise antibiotic chemotherapy and bacteriophage therapy. However, There are some setbacks to these therapies. The chemotherapy kills many kinds of bacteria, upsetting a healthy human microbiome, and the bacteriophage therapy relies on the use of a virus, which has a limited therapeutic potential as the host can develop specific antibodies against the virus.
Webometrics faces many challenges, not the least of which is a dearth of tools capable of measuring the Web with any degree of accuracy. Most academic and professional Webometrics analysts alike have had to rely on a mix of search engine downloads and query operators. Yet even analysts from organizations with their own crawlers are challenged by the limitations of methodologies and technologies.
Almost only devote religious people like Obama are allowed to climb to power in the West. Germany’s chancellor Merkel had to play down that she was a physicist in order to ensure the voters trust her to be aligned with the obsessions of her “Christian Democratic Union”.
In China, scientists decide at the highest level for many years. Science bloggers dream about secular people in the most important political positions, of science having effective influence "up there". While they yearn, secular scientists occupy the most important political positions in the most important country in the world.
