Scientists observed unusual transpolar auroral arcs during a geomagnetic storm in January 1997, contradicting existing models of the magnetosphere. The phenomenon was caused by energy propagating towards the dayside along the arc, indicating dynamic events in the magnetosphere.
Researchers at Savannah River Technology Center found metal-munching bacteria thriving in sterile storage pond environments, threatening long-term nuclear fuel rod integrity. This ill-timed discovery comes as a global downturn in nuclear reprocessing leads to extended storage periods.
Researchers at Georgia State University found over 15 types of fungi growing in car AC foam and glue, causing bad smells and allergic reactions. Sulphur-containing compounds are also responsible for the odors.
A solar flare on July 9, 1996, generated a massive seismic wave that resembles those created by terrestrial earthquakes. The seismic wave contained about 40,000 times the energy released in the San Francisco earthquake of 1906.
Duke University researchers have developed a new treatment that significantly extends the survival of patients with glioblastoma multiforme, the most malignant brain cancer. The treatment involves injecting antibodies carrying radioactive Iodine-131 directly into the tumor cells, achieving a median survival time of about 56 weeks.
A new computer simulation shows how a small cosmic cloud could suddenly burst the heliosphere, potentially leading to catastrophic climate changes and increased exposure to deadly cosmic radiation. The simulation may help guide Voyager 1 and 2 through a series of shock waves and a massive 'wall' in space nearly two decades from now.
Researchers at Arizona State University have found a large deposit of mineral hematite on Mars, suggesting the presence of hydrothermal activity and potentially water in the past. The find makes a strong case for future NASA missions to explore this area near the Martian equator.
Researchers discovered Cryptosporidium and Giardia parasites in 7.3% and 11.7% of stool samples from dogs, with puppies under 30 weeks old most affected. Despite no visible symptoms, these parasites can cause serious illness in humans.
Scientists have discovered giant convection cells on the sun, which could play a major role in its rotation and solar activity. These cells are large enough to swallow Jupiter and last for long periods, influencing space weather.
