| Is aging an accident of evolution?“The take-home message is that aging can be slowed and managed by manipulating signaling circuits within cells,” said Marc Tatar, PhD, a professor of biology and medicine at Brown University who was not involved in the research. “This is a new and potentially powerful circuit that has just been discovered for doing that.” |
| Exercise could be the heart's fountain of youthAbsence may make the heart grow fonder, but endurance exercise seems to make it younger. According to a study conducted at Washington University School of Medicine in St. Louis, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts. The researchers also showed that by one metabolic measure, women benefited more than men from the training. |
| Researchers unravel key mechanism of cellular damage in aging and diseaseResearchers have taken a first snapshot of how a class of highly reactive molecules inflicts cellular damage as part of aging, heart disease, stroke, cancer, diabetes, kidney disease and Alzheimer's disease to name a few. According to a study published today in the journal Cell, researchers have discovered a tool that can monitor related damage and determine the degree to which antioxidant drugs effectively combat disease. |
| Nanotech data storage breakthroughA breakthrough in technology could see the memory capacity of devices such as the iPod increase by 150,000 times, Glasgow University researchers claimed. |
| First active matrix display using nanowiresEngineers have created the first "active matrix" display using a new class of transparent transistors and circuits, a step toward realizing applications such as e-paper, flexible color monitors and "heads-up" displays in car windshields. |
| Fasting as a "Silver Shield" against CancerA better understanding of the body's responses to various factors will be more useful than more pharmaceuticals. Apparently the cells go into maintenance mode during starvation which is resistant to stress factors such as chemotherapy. |
| [Discussion] Does anyone know if anyone is seriously discussing post singularity events?The world after the singularity will be so radically changed that I think it is a fascinating topic given that the singularity could go so many different ways or maybe only a few different ways to one of sufficient intelligence.
Often it seems that the more you know and understand the more your options are limited if you have an ethical structure. Such as if you were gifted with a long term viewpoint it would seem that caring for the environment would become a top priority rather than a medium priority and possibly nurturing other life forms to be uplifted to sentience along with preventing extinction of useful species might seem more important than increasing computational power. |
| Bio-surgeryThis is awesome. Can't wait till these products are common especially if I ever get injured:) |
| Scientific literacyIn response to the nanotech post I thought this would further enlighten the conversation about the difficulty we face today. I've used Dr. Miller's research several times and it is impeccable.
Dr. Miller, 63, a political scientist who directs the Center for Biomedical Communications at the medical school, studies how much Americans know about science and what they think about it. His findings are not encouraging.
While scientific literacy has doubled over the past two decades, only 20 to 25 percent of Americans are "scientifically savvy and alert," he said in an interview. Most of the rest "don't have a clue." At a time when science permeates debates on everything from global warming to stem cell research, he said, people's inability to understand basic scientific concepts undermines their ability to take part in the democratic process. |
