Areturn to American culture may be the cure for America's decline, but Fallows' specific prescriptions for a group of domestic issues may not be acceptable to the patient. For example, the licensing and other regulation of professions--a recent phenomenon that Fallows says creates barriers for competent people seeking new jobs--is certainly not going to disappear in the near future, despite his recommendations...
Most explanations of that phenomenon liken the sun to a dynamo. Mighty currents of electricity flowing in the solar interior generate magnetic-field lines that, like the earth's, tend to be oriented in a north-south direction. But because the sun, unlike the earth, is gaseous, it does not rotate uniformly: bands of gases around the equator circle the solar axis once every 27 days, compared with a 34-day rotation rate near the poles...
...Labitzke of Berlin's Free University and NCAR's Van Loon have discovered a relationship between the solar cycle and the stratospheric winds over the tropics. During a 28-month period, these winds reverse direction, blowing half the time from the east, the other half from the west, a phenomenon meteorologists call the QBO, or quasi-biennial oscillation. Depending on the direction of the QBO flow, Labitzke and Van Loon found, solar maximums and minimums seem linked to changes in air pressure, temperatures, the number of storms and perhaps even the size of the notorious hole in the Antarctic ozone...
Jones said that Gai has an extremely sensitive neutron detector which would help them better understand the way the neutrons are emitted from the reactions. The latest studies indicate that the neutrons are emitted in sharp bursts, a phenomenon for which there is yet no explanation...
...detector will allow us to look at the bursts in much greater detail, so that we will be able to probe deeper [into] this phenomenon," Jones said. "We don't really understand how nature contrives to give us these neutrons, and that is the puzzle we have to unravel...
