A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine. 
Max Planck scientists discover brain cells in monkeys that may be linked to self-awareness and empathy in humans. 
Un mythe pourrait s’effondrer. On considérait que les taux de bon cholestérol étaient un bon indicateur des risques d’attaques cardiaques. Une étude génétique remet cette affirmation en cause, une seconde montre même qu’il est parfois néfaste. Le mauvais cholestérol, en revanche, reste lui fidèle à sa dénomination. 
Exercise clears the mind. It gets the blood pumping and more oxygen is delivered to the brain. But Dartmouth’s David Bucci thinks there is much more going on. 
Scientists have devised a method for repeatedly encoding, storing and erasing digital data within the DNA of living cells. In practical terms, they have devised the genetic equivalent of a binary digit -- a "bit" in data parlance. 
The name alone sounds so encouraging: HDL, the “good cholesterol.” The more of it in your blood, the lower your risk of heart disease. So bringing up HDL levels has got to be good for health. 
David Eagleman's Laboratory for Perception is located on the ground floor of Baylor College’s Ben Taub Medical Center, but the vibe is more creative think tank than clinical academic enclave. The walls are enamelled in dry-erase paint and marked up with impromptu sketches, arrows, and words like SYNESTHESIA spelled out in childish block letters. Coffee mugs are covered with to-do lists. There's not a single white coat on display.
The revelation that high-density lipoprotein, or HDL, is the “good cholesterol” has suffered a major blow. A meta-study involving over a hundred thousand participants used two different strategies to see if genetic mutations that increased levels of HDL also decreased risk for heart disease. In both cases the answer was a resounding no. The researchers were shocked when they saw the data. Now it’s their turn to shock HDL proponents and drug companies looking to cash in on the HDL craze. Partially hydrogenated oil is not the same as trans fat. The term "partially hydrogenated" means that hydrogen gas has been bubbled up into an oil to increase its degree of saturation and shelf life. The process of hydrogenation causes several chemical changes to occur in the oil. One of these changes (only one, but an important one) is the creation of trans fat. 
Hypertension, diabète et cancers font partie de ce que l’OMS appelle les maladies non transmissibles, en opposition aux maladies infectieuses. Ces maladies non transmissibles sont en forte hausse selon les dernières statistiques de l’OMS. Maladies cardiovasculaires et cancers vont tuer de plus en plus alors que les décès liés aux maladies infectieuses vont se réduire. L’OMS a analysé les données de 194 pays. 
Renate Raymond has encountered her fair share of organic food snobs, but a recent trip to a Seattle market left her feeling like she’d stumbled onto the set of Portlandia. 
Les statistiques montrent qu’environ 20% des personnes ayant reçu des implants de la hanche et des genoux son sujettes à des complications. Face à cela, des chercheurs de la MIT ont fait des recherches pour renouveler ces prothèses. 
Human embryonic stem cells can now be used to grow bone tissue grafts for use in research and potential therapeutic application. |
A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny luminescent crystals are safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine. 
A graphene sensor effectively tattooed onto a tooth can be used to detect bacteria and so wirelessly monitor oral health, research has shown. 
Scanadu, competing for the Tricorder X-Prize, epitomizes the hyperpersonalization of health care and the key to unleashing social media medicine. Social Medicine is the next big thing and a Facebook equivalent is in our future. Le fructose allié de la stupidité : Le fructose est une des nombreuses formes moléculaires de ce qu'on appelle le sucre. Comme son nom le laisse penser, on le retrouve de façon naturelle dans les fruits. 
Quel bonheur d’apprendre que la technologie unie à des mains expertes ont été capables de pratiquer une opération extrêmement compliquée avec succès! 
Une équipe de chercheurs de l’Hôpital pour enfants de Boston… annonce avoir obtenu la restauration de certaines éléments de base de la vision! 
Sleep-disordered breathing (SDB), commonly known as sleep apnea, is associated with an increased risk of cancer mortality, according to a new study. Microsoft co-founder Paul Allen founded the Allen Institute for Brain Science in 2003 with the aim of unlocking the secrets of the human brain. A human brain is 1,000 times as complex as a mouse brain. The neurons in a rat brain are in many respects functionally similar to those in a human brain. But given the daunting challenge of trying to understand something as complex as a human brain, brain researchers are starting with the more tractable issues involved in the operation of a mouse brain. 
The largest brain study of its kind had found a gene linked to intelligence, a small piece in the puzzle as to why some people are smarter than others. 
Findings suggest that the effects of exercise on memory depend on the age of the exerciser; underlying genetic mechanisms matter, too. 
Les molécules de gras mauvaises pour le cœur se trouvaient être les mêmes qui sont responsables de divers maux des fonctions cognitives et de mémoire… au moins chez les femmes. Comme le disait Karadoc « Le gras, c’est la vie ! ». 
Artificial intelligence has been the inspiration for countless books and movies, as well as the aspiration of countless scientists and engineers. Researchers at the California Institute of Technology (Caltech) have now taken a major step toward creating artificial intelligence—not in a robot or a silicon chip, but in a test tube. |
