POPSEarth's Magnetic Field Reversal is Approaching Here is another reason why humanity seems to lose direction.... :-) "Right now, historic records show that the strength of the magnetic field is declining very rapidly. From a quick back-of-the-envelope prediction, in 1,500 years the field will be as weak as it's ever been and we could go into a state of polarity reversal," says Singer. "One broad goal of our research is to provide some predictive capability for what could happen and what could be the signs of the next reversal."

POPSNo Sunspots in August Presage New Ice Age Man-made gases, one step up. Drop in solar activity, ten steps down. Gore and his cabal of politically motivated pseudo-scientists, complete idiots. The only responsible public policy is to devote our resources to adapt to climate change, not try to control it.

POPSOne hundred tesla without self-destructing Why would anyone need a magnet that strong? Greg Boebinger, director of the Magnet Lab, says that this magnetic field strength is the only way to test the properties of newly discovered high-temperature superconductors like iron oxyarsenide, which may improve the performance of MRI machines and high-voltage power lines while lowering their cost. A 100‑T magnet would also let you conduct certain zero-gravity experiments without traveling into space and let you develop magnetic propulsion systems that could eventually replace those that burn rocket fuel.

POPSCows and Their Internal Compass Unlike some city folks who have no clue as to north and south, cows and deer may have a built-in compass. A new study and observation reveals that not only birds and butterfly's but also large mammals may have a compass.

POPSBio-Earth: Are Planets Living Super-Organisms? He believes that expanding the study of life sciences to the core of our world and the depths of outer space will help us find distant relatives of our own Earth -- planets that could also sustain life. To explain why contintental plates drift on the surface of the Earth's molten mantle, Maruyama argues that continents actually have life cycles. Old, cold plates on continental fringes sink to “plate graveyards” deep in the Earth’s mantle, and then rise again, creating volcanoes fueled by three-dimensional convection movements deep below the surface.

POPSTrans-Atlantic MagLev -- A Magnetically Levitated Vacuum Tube Train A Maglev train floats about 10mm above the guidway on a magnetic field and is propelled by the guidway itself rather than an onboard engine by changing magnetic fields. An exotic proposal based upon this principle is the Trans Atlantic vactrain: a Maglev train in a long near-vacuum tube with speeds that allow less than one hour travel times between New York and London.
