The atmospheric waves of Venus, key to understanding the superrotation of its atmosphere, deciphered: Venus’ atmosphere rotates up to sixty times faster than its surface, a phenomenon known as superrotation whose origin hast yet to be satisfactorily explained...Venus is a slowly rotating planet since it takes about two hundred and forty three terrestrial days to complete a round about itself. Its atmosphere is expected to rotate with the same rhythm as well, but in the case of Venus it takes only four days. The origin and motor of this superrotation is so far unknown, but the numerous waves present in the planet’s atmosphere may play an important role. A study has just identified the nature of these waves for the first time.  "Venus is a mind bender for specialists in atmospheric dynamics. Its winds reach velocities higher than four hundred kilometers per hour, sevent... Read more » http://dlvr.it/6HD7cz

'Rosemary Is For Remembrance' - Science confirms wisdom of the ancients: "There's rosemary, that's for remembrance..."~ William Shakespeare Since ancient times, herbs have been appreciated for their profound therapeutic effects. Science as a form of evidence-gathering did not take the epistemological pole position until quite recently in cultural history, with the evidence of direct experience and the senses being the method and the means for ascertaining the medicinal value of plant medicines and foods for countless generations stretching back to the dawn of the human experience. Rosemary, a small perennial shrub in the mint family, is one such example, a plant woven deeply into ancient history and mythology, providing clues and hints to its particular value in cognition, memory and enhanced sensorial awareness, and ultimately ...

Astronomers bring the third dimension to a doomed star's outburst: In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun's mass and made it the second-brightest star in the sky. Now, a team of astronomers has used extensive new observations to create the first high-resolution 3-D model of the expanding cloud produced by this outburst."Our model indicates that this vast shell of gas and dust has a more complex origin than is generally assumed," said Thomas Madura, a NASA Postdoctoral Program fellow at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and a member of the study team. "For the first time, we see evidence suggesting that intense interactions between the stars in the central binary played a significant role in sculpting the nebula we ...

Scientists discover evidence of super-fast deep earthquake: As scientists learn more about earthquakes that rupture at fault zones near the planet’s surface — and the mechanisms that trigger them — an even more intriguing earthquake mystery lies deeper in the planet.Scientists at Scripps Institution of Oceanography at UC San Diego have discovered the first evidence that deep earthquakes, those breaking at more than 400 kilometers (250 miles) below Earth’s surface, can rupture much faster than ordinary earthquakes. The finding gives seismologists new clues about the forces behind deep earthquakes as well as fast-breaking earthquakes that strike near the surface.Seismologists have documented a handful of these events, in which an earthquake’s rupture travels faster than the shear waves of seismic energy that it radiates....

New lava flows observed on the Sciara del Fuoco, Stromboli volcano - Italy: Two new lava overflows occurred from the NE vent of Stromboli volcano - Aeolian Islands, Italy, last evening and this morning, July 10, 2014.Similar as during the previous episodes, the flows were the result of surges in magma supply, quickly descended the upper part of the Sciara del Fuoco, and then stopped, VolcanoDiscovery reports.Video courtesy of VolcanoDiscoveryGeologic summarySpectacular incandescent nighttime explosions at Stromboli volcano have long attracted visitors to the "Lighthouse of the Mediterranean." Stromboli, the NE-most of the Aeolian Islands, has lent its name to the frequent mild explosive activity that has characterized its eruptions throughout much of historical time. The small, 924-m-high island of Stromboli is the emergent summit of a volcano that ... Read more » http://dlvr.it/6H5HC6

Neoguri weakens into tropical storm, brings heavy rainfall across Japan: Neoguri has quickly weakened as it made landfall over Japan, but it will still bring heavy rain and possible mudslides. Land interaction and cooler waters weakened Neoguri in to tropical storm system. Neoguri is predicted to become extra-tropical low system during the next 12 hours.According to JMA the system is moving northeastward at speed of 45 km/h (28 mph). Maximum sustained winds are 80 km/h (50 mph) with gusts up to 120 km/h (75 mph).MTSAT IR satellite image taken at 03:30 UTC (left) and visible satellite image at 04:01 UTC on July 10, 2014. (Credit: NOAA/UW-CIMSS)Neoguri is the strongest typhoon so far in the 2014 Western Pacific season. Neoguri has claimed 3 lives and left 45 injured over the past several days. At least 27 homes have been destroyed in Okinawa and... Read more » http://dlvr.it/6GxtyZ

NASA's RapidScat to unveil hidden cycles of sea winds: Ocean waves, the hot sun, sea breezes -- the right combination makes a great day at the beach. A different combination makes a killer hurricane. The complex interactions of the ocean and the air above it that can create such different outcomes are not yet fully known. Scientists would especially like to understand the role that the daily heat of the sun plays in creating winds.In a few months, NASA will send an ocean wind-monitoring instrument to a berth on the International Space Station. That unique vantage point will give ISS-RapidScat, short for the International Space Station Rapid Scatterometer, the ability to observe daily (also called diurnal) cycles of wind created by solar heat.Winds contribute to motion in the ocean on every scale, from individual waves to currents extending tho...

MESSENGER and STEREO measurements open new window into high-energy processes on the Sun: Understanding the sun from afar isn't easy. How do you figure out what powers solar flares – the intense bursts of radiation coming from the release of magnetic energy associated with sunspots – when you must rely on observing only the light and particles that make their way to near-Earth’s orbit?One answer: you get closer. NASA's MESSENGER spacecraft -- which orbits Mercury, and so is as close as 28 million miles (45 million km) from the sun versus Earth's 93 million miles (149 million km) -- is near enough to the sun to detect solar neutrons that are created in solar flares. The average lifetime for one of these neutrons is only 15 minutes.  How far they travel into space depends on their speed, and slower neutrons don't travel far enough to be...
