Storms on Jupiter

Probably caused by man-made global warming. They have SUV’s on Jupiter, right?

jupiter's storm in visible light

The team monitored the new eruption of cloud activity and its evolution with an
unprecedented resolution using NASA’s Hubble Space Telescope, the NASA Infrared
Telescope Facility in Hawaii, and telescopes in the Canary Islands (Spain). A network
of smaller telescopes around the world also supported these observations.
the bright plumes were storm systems triggered in Jupiter’s deep water clouds that moved upward in the atmosphere vigorously and injected a fresh mixture of ammonia ice and water about 20 miles (30 kilometers) above the visible clouds.
The storms moved in the peak of a jet stream in Jupiter’s atmosphere at 375 miles per hour (600 kilometers per hour). Models of the disturbance indicate that the jet stream extends deep in the buried atmosphere of Jupiter, more than 60 miles (approximately100 kilometers) below the cloud tops where most sunlight is absorbed.

NASHVILLE, Tenn.—New research from Vanderbilt University shows for the first time that the brain processes aggression as a reward – much like sex, food and drugs – offering insights into our propensity to fight and our fascination with violent sports like boxing and football.

Arctic ocean circulation do an about-face

Refreezing Arctic – something that Algore isn’t yelling about, is he?
clipped from earthobservatory.nasa.gov
A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales.
The team of scientists found a 10-millibar decrease in water pressure at the bottom of the ocean at the North Pole between 2002 and 2006, equal to removing the weight of four inches of water from the ocean. The distribution and size of the decrease suggest that Arctic Ocean circulation changed from the counterclockwise pattern it exhibited in the 1990s to the clockwise pattern that was dominant prior to 1990.
authors attribute the reversal to a weakened Arctic Oscillation, a major atmospheric circulation pattern in the northern hemisphere. The weakening reduced the salinity of the upper ocean near the North Pole, decreasing its weight and changing its circulation.
many changes seen in upper Arctic Ocean circulation in the 1990s were mostly decadal in nature, rather than trends caused by global warming

Million Light Year Long Particle Beam Found

Remarkable

clipped from space.newscientist.com

Colossal black holes at the centres of active galaxies power jets of matter that stretch far into space (Illustration: NASA)

An intergalactic particle beam stretching for more than a million light years is the longest ever seen.
The jet they saw is nearly 1.5 million light years long, twice the length of the previous record holder. If this jet sprang instead from the centre of the Milky Way, it would loom over us like a skyscraper and would stretch halfway to the Andromeda galaxy.
It is unusual in other ways too. Jets usually come in fairly well-matched pairs, pointing in opposite directions. The new jet’s counterpart, however, appears much shorter. That could be because the apparently shorter jet is pointing away from us – so light from its far end might not have had time to reach us yet.
Interestingly, the radio waves emitted by the newly discovered jet are strongly polarised, revealing a powerful magnetic field wrapped around the jet.

When To Care For, Abandon, or Eat Your Offspring

A new suggestion for Thanksgiving dinner?

clipped from americandigest.org
Ah, what would we do without science to keep us on the moral path?
cannibalidss.jpg“When to care for, abandon, or eat your offspring: the evolution of parental care and filial cannibalism,”

….highlights the potential importance of a range of factors in the evolution of filial cannibalism using a mathematical model of analysis. It is potentially affected by the ability to selectively consume lower quality offspring, preferences associated with mate choice, density-mediated survival, and population dynamics. Professor Michael Bonsall, a Royal Society Research Fellow and University Lecturer in Mathematical Biology at Oxford University, said: ‘This sort of behaviour – cannibalising your offspring – is widespread amongst different animal groups. We show that there is not a single benefit to eating your offspring, and it depends on several factors and explanations.’

Unless, of course, you are stranded with a kindergarten class on a desert island in Colorado after global warming kicks in.

Hubble Sees Graceful Dance Of Two Interacting Galaxies

clipped from www.sciencedaily.com

Arp 87 is a stunning pair of interacting galaxies. Stars, gas and dust flow from the large spiral galaxy, NGC 3808, forming an enveloping arm around its companion. The shapes of both galaxies have been distorted by their gravitational interaction. Arp 87 is located in the constellation of Leo, the Lion, approximately 300 million light-years away from Earth. Arp 87 appears in Arp’s Atlas of Peculiar Galaxies. As also seen in similar interacting galaxies, the corkscrew shape of the tidal material suggests that some stars and gas drawn from the larger galaxy have been caught in the gravitational pull of the smaller one. This image was taken in February 2007 with Hubble’s Wide Field Planetary Camera 2 detector. (Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA))

Scientists Find Oldest Living Animal, Then Kill It

Scientists Find Oldest Living Animal, Then Kill It

British marine biologists have found what may be the oldest living animal — that is, until they killed it.

Only after researchers cut through its shell, which made it more of an ex-clam, and counted its growth rings did they realize how old it had been — between 405 and 410 years old.
“Its death is an unfortunate aspect of this work, but we hope to derive lots of information from it,” postdoctoral scientist Al Wanamaker told London’s Guardian newspaper. “For our work, it’s a bonus, but it wasn’t good for this particular animal.”
