Pessimists 42% more likely to die earlier than Optimists
contributed by member on 2006-12-27
|
|
A study reported in the Mayo Clinic Proceedings of December 2006 shows that pessimists tend to die sooner than optimists.
"These latest findings are based on a 40-year follow-up of 6,958 men and women who entered the University of North Carolina, Chapel Hill in the mid-1960s. At the time, they took a standard personality test that gauges a person's tendency to be optimistic or pessimistic." |

A 35 year old Japanese man has supposedly made a full recovery after spending three weeks in hypothermia without food or water.
"Mitsutaka Uchikoshi had almost no pulse, his organs had all but shut down and his body temperature was 71 degrees Fahrenheit when he was discovered on Rokko mountain in late October, said doctors who treated him at the nearby Kobe City General Hospital. He had been missing for 24 days." |

"We plan to use the devices to control the output of ribosome-like DNA devices. Systems responsive to RNA can report on the state of the solution and build molecules in response to that input" says Seeman. "This will be real hard." |

Dendritic spines found to be electrical adding machines
contributed by member on 2006-12-08
|
|  |
|
Dendritic spines of neurons in humans have been found to modulate an electrical signal depending on their length. It was long believed with little evidence that the spines functioned biochemically but now research by Rafael Yuste and colleagues at Howard Hughes Medical Institute at Columbia University have shown this is not the case.
Yuste says "Our findings are consistent with the hypothesis that the purpose of the filtering we discovered is to enable neurons to linearly integrate inputs without interfering with one another." |

Dendritic spine home movie from Duke University
contributed by member on 2006-12-08
|
|
"When the scientists triggered the neurons, they saw the recycling endosomes, labeled with a green dye, streaming up and down the neurons, dipping in and out of the dendritic spines. Inside the dendritic spines, the recycling endosomes deposited pieces of recycled proteins that grew new spines or changed the shape and size of existing spines, Ehlers said." |
