Magnetic fields explosively release energy in events throughout the universe, from experiments conducted in laboratories to huge outbursts within galaxies. On the Sun, these magnetic explosions are responsible for solar flares and ejections of material from the Sun’s corona.
Similar events associated with Earth’s magnetic field drive magnetic storms, and the dramatic brightening and expansion of the northern and southern lights, the aurora borealis and aurora australis. The reconnection of
An international team of marine geologists has just completed an expedition to an area off the coast of Surinam known as the Demerara Rise. The scientists were part of the two-month Leg 207 of the NSF-supported Ocean Drilling Program (ODP) expedition in the equatorial Atlantic Ocean. The project studied periods in Earths history that have undergone rapid climate and ocean circulation changes and likely led to mass extinctions of plants and animals.
Three decades ago, geologists found s
New data shows that the antiepileptic drug Keppra (levetiracetam), when used alone and in combination with other treatments, provided relief to more than 90 percent of patients with a range of pain syndromes, from migraine headaches to neck and back pain. The study of 400 patients, conducted by the Statesville Pain Associates of Statesville, N.C., was presented today at the American Pain Societys 22nd Annual Scientific Meeting.
“To date, studies of Keppra to treat pain have been condu
A team of investigators at Carnegie Mellon University has formed the first hybrid quadruplex of peptide nucleic acids, or PNAs, with DNA, the genetic code. This result opens new opportunities to study the activity of genetic regions occupied by recently described quadruplex DNA structures, as well as providing a new compound that could be used as a biosensor or to block gene activity associated with diseases such as cancer. The research results, published online, will appear in a forthcoming issue o
Cell phones, CD players and flashlights all wear down batteries far faster than we might wish. But theres new hope, now that researchers at the Department of Energys Idaho National Engineering and Environmental Laboratory (INEEL) have overcome another barrier to building more powerful, longer-lasting lithium-based batteries.
The INEEL team, led by inorganic chemist Thomas Luther, discovered how lithium ions move through the flexible membrane that powers their patented rechargeab
Since the late 1970s, the amount of solar radiation the sun emits, during times of quiet sunspot activity, has increased by nearly .05 percent per decade, according to a NASA funded study.
“This trend is important because, if sustained over many decades, it could cause significant climate change,” said Richard Willson, a researcher affiliated with NASAs Goddard Institute for Space Studies and Columbia Universitys Earth Institute, New York. He is the lead author of the study rece
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
