Tracking a hot spot

05-17-2007 · EurekAlert!

Using a state-of-the-art satellite imagery technique, researchers can more precisely predict volcanic activity, bringing them closer to understanding where eruptions may occur. A new study in Science this week examines Mauna Loa's volcanic activity. With this new technique, researchers can more precisely forecast locations of volcanic activity -- providing critical information to improve warning systems and hazard assessment of populated areas surrounding one of the world’s most naturally dangerous ecosystems, volcanoes.

Astronomers find puzzling dwarf star with complex magnetic fields
12-05-2007 · EurekAlert!
Typically, little M-dwarf stars -- the most common type of star in the galaxy -- are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform. It has an unusually active and complex magnetic field, stronger than our own Sun's, and a huge hot spot that covers half of its surface.

Towards a better understanding of hot spot volcanism
01-31-2008 · EurekAlert!
Researchers from the IRD and the University of Chile investigated the phenomena that led to the recent activity of seven hot spots located in the central Pacific. Numerical mechanical models showed that variations in movement of the Pacific plate, generating shearing stresses within it, could facilitate the rise of magma towards the surface. This discovery, if corroborated, would indicate that the formation of certain hot spots depended on the movement of the tectonic plates.

'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
02-08-2008 · EurekAlert!
Catalysts typically break down an oxygen molecule into two identical atoms that behave the same. But on a titanium oxide catalyst, the two atoms of a split oxygen molecule act differently: one fills a vacant spot on the catalytic surface and the other acquires extra energy and can move away. If the finding turns out to be important to reactivity, it might also be useful in hydrogen production or to break down pollutants.

Hot spot on Enceladus causes plumes
12-17-2007 · EurekAlert!
Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so hot intellectually hot, it's smokin'. The hot spot is causing plumes of ice and vapor to arise above Enceladus, says Washington University's William B. McKinnon.

Sister Planet: Mission to Venus reveals watery past
12-01-2007 · Science News Online
The Venus Express probe has found evidence that Venus once had more water than it does today, and has provided new measurements of the weather on Venus, proof of lightning on the planet, and signs of a formerly unknown hot spot near its south pole.

Odd little star has magnetic personality
12-05-2007 · EurekAlert!
Observations that included the Gemini Observatory show that a very low-mass star has unexpected magnetic activity and a hot spot that could cover one-half of its surface.

Helping Build Designs That Are 'Cool'
10-05-2006 · ScienceDaily
Cool design creates hot profits, and although really great design is an art rather than a craft, the E-VaN project has developed some best-practice design tools to help companies maximise their potential. E-VaN aims to usher in a new wave of design that allies form with function.

'Good vibrations' from deep-sea smokers may keep fish out of hot water
02-05-2007 · EurekAlert!
"Editors' Choice" in the current issue of Science magazine, tags them, "Singing Vents." Long assumed to be silent, fluids in black smoker hydrothermal vents not only produce a rumbling sound but, as an added surprise, are producing resonant tones. Have a listen to what University of Washington scientists have recorded.
