In the 1980s, scientists captured the precise mechanics of a protein machine. It looked strange, to researchers its tall thin structure with stubby legs invoked the enchanted broomstick that stole the show in "The Sorcerer's Apprentice" segment of Disney's 1940 Fantasia film.
What made the wealthy elites in San Fransisco and Seattle who deny the benefits of child vaccines suddenly clamor for government action to create more vaccines? Two cases of Ebola in the United States.
Though 12,000 people died of heart disease in that same time, and their states were leading the nation in preventable debilitating childhood diseases, it got little media, and therefore consumer, attention. There is a reason why. In the modern environment of surveillance medicine and the focus on risk factors for disease, the lines between health and illness have become blurry and even skewed, according to sociological surveys.
Using commercial solar cells, researchers have converted over 40 percent of the sunlight hitting a solar system into electricity, the highest efficiency ever reported.
A study has found that elite Kenyan athletes have greater brain oxygenation during periods of maximum physical effort, which contributes to their success in long-distance races.Dr. Jordan Santos-Concejero, of the Department of Physical Education and Sport at the University of the Basque Country carried out the research to analyze the response of cerebral oxygenation at maximum and progressive rhythms amongst elite Kenyan runners from the Kalenjin tribe.
Researchers from the University of Hawai'i (UH) and NOAA's Office of National Marine Sanctuaries today announced the discovery of an intact "ghost ship" in 2,000 feet of water nearly 20 miles off the coast of Oahu - the former cable ship Dickenson, later the USS Kailua.
Launched in Chester, Pennsylvania in early 1923 for the Commercial Pacific Cable Company, Dickenson was part of a global network of submarine cable that carried telecommunications around the world. Repairing cable and carrying supplies, Dickenson served the remote stations at Midway and Fanning Island from 1923 until 1941. it arrived in Pearl Harbor with evacuees from Fanning Island on December 7th, during the Japanese attack that brought America into World War II.
The chemical messenger dopamine, colloquially called the 'happiness hormone', is important outside social psychology articles on Valentine's Day also; it has been linked to motivation and motor skills and may help neurons with difficult cognitive tasks. Researchers have found how dopamine influences brain cells while processing rules.
Skin color varies according to latitude and therefore by the intensity of incident ultraviolet light; according to biologists, that is why individuals living at low latitudes developed darker skin, whereas those living at high latitudes ended up with paler pigmentation. Yet the mutations that lightened the skin, probably owing to the need to synthesize vitamin D at latitudes with less solar irradiation, also increase the probability of developing melanoma or skin cancer, which is a negative in natural selection.
A new article in the Georgia Law Review
details the relationship of two U.S. Supreme Court cases, their impact on freedom of expression, and how they relate to blogging and citizen journalism.
Psychology surveys have found that when people go to bed and thus how long they sleep at a time might actually make it difficult for people to stop worrying.
The surveys showed that people who sleep for shorter periods of time and go to bed very late at night often have more negative thoughts than those who keep regular sleeping hours.
Alzheimer's disease progresses inside the brain as deposits of the toxic protein amyloid-beta (Aβ),overwhelm neurons. A side effect of accumulating Aβ in neurons is the fragmentation of the Golgi apparatus, the part of the cell involved in packaging and sorting protein cargo including the precursor of Aβ. Or it may be the other way around and loss of Golgi function is a driving force behind Alzheimer's.
Yanzhuang Wang, Gunjan Joshi, and colleagues at the University of Michigan, Ann Arbor, set out to uncover the mechanism damaging the Golgi using a transgenic mouse and tissue culture models of
Alzheimer's disease
to look at what was going on.
Epidemiologists have examined the relationship between body weight and life expectancy and say that overweight and obese individuals have the potential to decrease life expectancy by up to 8 years.
If diabetes or cardiovascular disease develop, that could shorten life expectancy ever more, according to their analysis of data from the National Health and Nutrition Examination Survey (years 2003 to 2010) which was used to estimate the annual risk of diabetes and cardiovascular disease in adults with different body weights.
The data from almost 4,000 individuals was also used to analyze the contribution of excess body weight to years of life lost and healthy years of life lost.
A new technique involves wrapping chemotherapy drugs in a liposome - a fatty cover - and it reduces heart damage that would otherwise occur, according to a presentation by Professor Jutta Bergler-Klein and Professor Mariann Gyöngyösi from the Medical University of Vienna, at
EuroEcho-Imaging 2014.
The Obamacare website is not the only thing that debuted incomplete, buggy, difficult to use and nonetheless mandated. The Open Payments Program database, also known as the Physician Payments Sunshine Act, was 12 years in the making and designed to report drug and device industry payments to physicians, but it came onto the scene with a resounding thud, burdensome to most and helping almost no one. But it is too important to dismiss before its shortcomings are addressed, say the authors of a Viewpoint in JAMA.
