The December GSA TODAY science article, "Unique geologic insights from “non-unique” gravity and magnetic interpretation,” is now online at www.geosociety.org/gsatoday/. All GSA Today articles are open access. In many fields of applied science, such as geology, there are often tensions and disagreements between scientists who specialize in analyses of problems using mathematical models to describe sets of collected data, and those that rely on on-the-ground observations...

Image 1 - 2012: Magnetic Pole Reversal Happens All The (Geologic) Time
2011-12-01 11:41:28

Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to 'south.' This is because a magnetic compass is calibrated based on Earth's poles. The N-S markings of a compass would be 180 degrees wrong if the polarity of today's magnetic field were reversed. Many doomsday theorists have tried to take...

News from the 53rd Annual Meeting of the APS Division of Plasma Physics To achieve nuclear fusion for practical energy production, scientists often use magnetic fields to confine plasma. This creates a magnetic (or more precisely "magneto-hydrodynamic") fluid in which plasma is tied to magnetic field lines, and where regions of plasma can be isolated and heated to very high temperatures–typically 10 times hotter than the core of the sun! At these temperatures the plasma is nearly...

New Model May Explain Magnetized Moon Rocks
2011-11-10 06:06:46

A team of scientists has proposed a novel model for the generation of a global magnetic field in the ancient moon, something that could help solve a decades-old mystery about the presence of magnetized rocks on the moon´s surface. Since the moon currently has no global magnetic field, these rocks have puzzled experts since the days of the Apollo program. The Earth´s magnetic field exists because it has a spinning solid core surrounded by hot metallic liquid, which churns...

Each year, plant viruses and fungal attacks lead to crop losses of up to 30 percent. That is why it is important to detect plant disease early on. Yet laboratory tests are expensive and often time-consuming. Researchers are now developing a low-cost quick test for use on site. The farmer casts a worried gaze at his potato field: where only recently a lush green field of plants was growing, much of the foliage has now turned brown — presumably the result of a fungal disease. Usually,...

New floating microscopic device will allow researchers to study a wide range of cellular processes It´s a bit of a challenge. But, imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then imagine that the soap in the cleaning solution is replaced with various molecules that can be selectively delivered to the cells. This gives you a sense of a new device that researchers believe will serve as a powerful tool to...
