IF THERE IS a technological revolution in progress, rich economies could be forgiven for wishing it would go away. Workers in America, Europe and Japan have been through a difficult few decades. In the 1970s the blistering growth after the second world war vanished in both Europe and America.
Continue reading page |1| 2 Evidence is emerging that some widely used drugs can prolong lifespan for well people - and insiders have started taking them off-label MILLIONS of people are taking anti-ageing drugs every day - they just don't know it.
A new MIT study offers a way out of one of solar power's most vexing problems: the matter of efficiency, and the bare fact that much of the available sunlight in solar power schemes is wasted. The researchers appear to have found the key to perfect solar energy conversion efficiency-or at least something approaching it.
Is it how fast the reaction happens vs. the cost of such a machine? Is it more efficient to just plant trees/algae? Why is nobody considering this?
"I wish it were possible, from this instance, to invent a method of embalming drowned persons, in such a manner that they might be recalled to life at any period, however distant; for having a very ardent desire to see and observe the state of America a hundred years hence, I should prefer to an ordinary death, the being immersed in a cask of Madeira wine, with a few friends, until that time, then to be recalled to life by the solar warmth of my dear country.
It's a solar cell! No... it's a rechargeable lithium-air battery! No... wait... it's both: It's the world's first all-in-one solar battery! This is significant, because one of the biggest problems with wide-scale solar power deployment is that you also need huge banks of batteries to store electricity.
JUST ACROSS THE road from Gothenburg's main railway station, at the foot of a pair of hotels, a line of taxis is waiting to pick up passengers. The drivers, all men, many of them immigrants, chat and lean against their vehicles, mostly Volvos.
It only takes about 10 liters of a newly-developed form of crystalline cobalt salt to steal the air from a room, or at least the 21 percent or so of that air comprised of oxygen. Given the right conditions, with the temperature and atmospheric pressure just so, it could take as little as seconds for the material to do its work.

Researchers at MIT and Northeastern University have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port.
A virus that shuttles a therapeutic gene into cells has strengthened the muscles, improved the motor skills, and lengthened the lifespan of mice afflicted with two neuromuscular diseases. The approach could one day help people with a range of similar disorders, from muscular dystrophy to amyotrophic lateral sclerosis, or ALS.
If life-expectancy trends continue, that future may be near, transforming society in surprising and far-reaching ways. For millennia, if not for eons-anthropology continuously pushes backward the time of human origin-life expectancy was short. The few people who grew old were assumed, because of their years, to have won the favor of the gods.
Using modern statistical tools, a new study led by the University of Washington and the United Nations finds that world population is likely to keep growing throughout the 21st century. The number of people on Earth is likely to reach 11 billion by 2100, the study concludes, about 2 billion higher than widely cited previous estimates.
