Learning changes the brain’s circuitry
When a person learns a new task, there is a measurable change in his or her spontaneous brain activity, earlier believed to be “white noise”, according to researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy. It was also found that the degree of change reflects how well subjects have learned to perform the task. “Recent studies have shown that in the absence of any overt behaviour, and even during sleep or anaesthesia, the brain’s spontaneous activity is not random, but organized in patterns of correlated activity that occur in anatomically and functionally connected regions,” says senior author Dr. Maurizio Corbetta.... |

Shingles Raises Risk Of Stroke In Adults
Adults with shingles were about 30 percent more likely to have a stroke during a one-year follow-up than adults without shingles. According to a study published in Stroke: Journal of the American Heart Association the risk was even greater when the infection involved the eyes. Every 40 seconds someone in America has a stroke, according to the American Association for Critical Illness Insurance. Stroke is the leading cause of serious, long-term disability in the United States... See related |

Scientists hope work with poison gas can be a lifesaver
Awiry, slightly hunched man presses in a few numbers, the electronic lock gives way with a beep and the group presses into the crowded laboratory, plastered with ominous warnings about toxins and biohazards. Guiding the visitors at the Fred Hutchinson Cancer Research Center is Mark Roth, a 50-year-old biologist with a tall forehead, thinning red hair and a perpetual wry smile. He asks his assistant, Jennifer Blackwood, if the rat is ready. It is. She turns a dial, and the sealed enclosure starts to fill with poison gas -- hydrogen sulfide. An ounce could kill dozens of people. The rat sniffs the air a few times, and within a minute, his naturally twitchy movements are almost still. On a monitor that shows his rate of breathing, the lines look like a steep mountain slope, going down. At first glance, that looks bad. We need oxygen to live. If you don't get it for several minutes -- for example, if you suffer cardiac arrest or a bad gunshot wound -- you die. But something else is going on inside this rat. He isn't dead, isn't dying. The reason why, some people think, is the future of emergency medicine....... |

Fellow Inmates Ease Pain of Dying in Jail
Allen Jacobs lived hard for his 50 years, and when his liver finally shut down he faced the kind of death he did not want. On a recent afternoon Mr. Jacobs lay in a hospital bed staring blankly at the ceiling, his eyes sunk in his skull, his skin lusterless. A volunteer hospice worker, Wensley Roberts, ran a wet sponge over Mr. Jacobs’s dry lips, encouraging him to drink. Come on, Mr. Jacobs,” he said. Mr. Roberts is one of a dozen inmates at the Coxsackie Correctional Facility who volunteer to sit with fellow prisoners in the last six months of their lives. More than 3,000 prisoners a year die of natural causes in correctional facilities,,,,. |

'Ethical' stem cell crop boosted
US researchers have found a way to dramatically increase the harvest of stem cells from adult tissue. It is a practical step forward in techniques to produce large numbers of stem cells without using embryos. Using three drug-like chemicals, the team made the procedure 200 times more efficient and twice as fast, the Nature Methods journal reported. It is hoped stem cells could one day be widely used to repair damaged tissue in diseases and after injuries. Much of the work on stem cells has focused on those taken from embryos as they have an unlimited capacity to become any of the 220 types of cell in the human body - a so-called pluripotent state.´... |

Science to 'stop age clock at 50'
Centenarians with the bodies of 50-year-olds will one day be a realistic possibility, say scientists. Half of babies now born in the UK will reach 100, thanks to higher living standards, but our bodies are wearing out at the same rate. To achieve "50 active years after 50", experts at Leeds University are spending £50m over five years looking at innovative solutions. They plan to provide pensioners with own-grown tissues and durable implants. New hips, knees and heart valves are the starting points, but eventually they envisage most of the body parts that flounder with age could be upgraded.,,,, |

Are Artificial Sweeteners Really That Bad for You?
Too much sugar will make you fat, but too much artificial sweetener will ... do what exactly? Kill you? Make you thinner? Or have absolutely no effect at all? This week marks the 40th anniversary of the Food and Drug Administration's decision to ban cyclamate, the first artificial sweetener prohibited in the U.S., and yet scientists still haven't reached a consensus about how safe (or harmful) artificial sweeteners may be. Shouldn't we have figured this out by now? Read more abt it |

Are Artificial Sweeteners Really That Bad for You? Too much sugar will make you fat, but too much artificial sweetener will ... do what exactly? Kill you? Make you thinner? Or have absolutely no effect at all? This week marks the 40th anniversary of the Food and Drug Administration's decision to ban cyclamate, the first artificial sweetener prohibited in the U.S., and yet scientists still haven't reached a consensus about how safe (or harmful) artificial sweeteners may be. Shouldn't we have figured this out by now? Read more abt it Some diabetics have gathered a number of links to this subject, including some on scientific research on this, since they already know that sugar has more than the usual bad effects on them, and that simple Google searches on this subject mainly show that people spreading misinformation on this subject are much more active than those spreading information that can be traced to scientific reports. For example, some links that diabetics consider useful: http://www.greenfacts.org/en/aspartame/index.htm http://www.snopes.com/medical/toxins/aspartame.asp http://archives.chicagotribune.com/2008/nov/3...sun-stevia-sweetner-nov30 http://www.foodnavigator.com/Legislation/Stevia-sweetener-gets-US-FDA-go-ahead http://www.mayoclinic.com/health/stevia/AN01733 http://www.purdue.edu/UNS/html4ever/2004/040629.Swithers.research.html http://abouterythritol.homestead.com/ http://www.aspartame.org/aspartame_experts_science.html http://www.aboutaspartame.com/pdf/The_Truth_About_Aspartame_Fact_Sheet.pdf http://web.archive.org/web/20071018041739/htt...tures/1999/699_sugar.html Stevia has only recently been approved by the FDA, due to delays in getting anyone to pay for enough scientific research to justify this. A number of diabetics say that various sugar alcohols are know to act as laxatives for some people, act about the same as sugars for others, and act as good artificial sweeteners for still others. A number of the articles with misinformation about aspartame ignore the fact that digestion of many natural foods produces more methanol than using aspartame in normal amounts does. They have also found that the fructose type of sugar can have some bad effects on them if they consume too much of it, even though it does not raise their blood glucose. http://www.medicalnewstoday.com/articles/147135.php If you find any similar links about high-fructose corn syrups containing mercury, be wary of their accuracy. It seems that these articles were based mostly on an announcement of scientific results that did NOT take enough account of just how small amounts of mercury recent methods of analyzing for mercury have become able to detect. |
