UPDATE - 9/30@9:53AM: Apparently the band and crew played golf at The
Trophy Club of Atlanta golf course yesterday afternoon according to a
post on the Club's Facebook page (thanks Nicecoldbeer):
Rush concert tonight at the Verizon Wireless Ampitheater. The band and all
their crew played golf here yesterday and they were a blast to have out here.
We got a good picture with the band, pic to follow...

Under steady 60-mph winds, “the ocean model produces an area of exposed mud
flats where the river mouth opens into the lake,” wrote National Center for
Atmospheric Research oceanographers Carl Drews and Weiqing Han in an August 30
Public Library of Science One study. “These mud flats represent the
area of crossing, and the crossing party would observe water to their left and
In the Book
of Exodus, Moses is described as leading Israelite slaves in flight from
Egypt, arriving at the Red Sea’s shores just ahead of pursuing armies. At that
point, “Moses stretched out his hand over the sea; and the Lord caused the sea
to go back by a strong east wind all that night, and made the sea dry land, and
the waters were divided.”
Han and Drews, who hosts a
website dedicated to the compatibility of science and Christian faith, don’t
consider the Exodus narrative to be literally true, but rather “an interesting
and ancient story of uncertain origin.” Others have been similarly intrigued,
suggesting that a rare phenomenon called wind setdown could have created dry
passage across the Red Sea’s narrow northern tip. A wind setdown is essentially
the flip side of a storm surge; when strong, steady winds cause water to rise
dramatically in some areas, it necessarily drops in others.
In 1879, theologian Samuel Bartlett proposed a setdown location at a shallow
inlet near of Suez, used by Arabs to cross the Red Sea at low tide. More
recently, Russian researchers Naum Voltzinger and Alexei Androsov calculated
that a 74-mph wind could have exposed an underwater reef near what is now the
In the new study, Han and Drews determined that the depressions in the reef
would have stayed underwater. They propose a different
location, 75 miles north of the reef and just south of the Mediterranean, in
what is now known as the Kedua Gap. The area is now dry, but historical
reconstructions suggest an ancient branch of the Nile once flowed into a lagoon
After using satellite measurements and archaeological records to create a
model of local hydrogeography, the researchers ran simulations that found 12
hours of 60-mph easterly winds would have exposed a dry passage, 2 miles long
and 3 miles wide, out of Egypt.
When the winds stopped blowing, the waters would surge back, appearing in the
researchers’ words “as an advancing wall of churning water” — or, per Exodus,
“the waters returned, and covered the chariots, and the horsemen, and all the
host of Pharaoh that came into the sea after them; there remained not so much as
one of them.”
“If a crossing actually took place here, any debris field of military
artifacts should be found to the north of the gap,” wrote Han and Drews.

The cracks in ice could have served as a safe environment — much like a cell
— for the first life on Earth to replicate and evolve.
The study adds plausibility to the ‘RNA World’
hypothesis that argues life began with a single stranded molecule capable of
“I always thought that the idea of an RNA world was exciting, but that RNA
was a perverse choice of primordial material because it was hard to imagine
chemical conditions under which they could survive on the early earth,” said
biologist Philipp Holliger of MRC Laboratory of Molecular Biology in the United
Kingdom, who led a study in Nature
Communications September 21.
“What we’ve found is that RNA would have been much happier in the ice than in
hydrothermal vents, where it would have lasted only a few seconds,” Holliger
Holliger was inspired to study how RNA replicates
in icy conditions by a 2004
study that found when nucleotides — the building blocks of genetic code —
are frozen in ice, they spontaneously assemble into random strands of RNA.
If nucleotides were present in the ice on early Earth, they could have formed
uncountable combinations of these random genetic strands, many of which would
have been meaningless. But a few of the strands might have contained the right
genetic code to begin self-replication.
Over time, the replicating RNA strands would have mutated and changed with
some of them surviving better than others, beginning the long chain of evolution
towards more complex organisms.
By testing the process out in beakers, adding water, salts, RNA building
blocks, and ribosomes — an
RNA-derived molecule that serves as a center for the further RNA replication —
Holliger found that liquid pockets ice would have served as an essential
container for this process to occur. The cold would have also kept the molecules
“It’s like the tortoise and the hare problem,” Holliger said. “The tortoise
is slower, but it keeps on going, rather than falling apart. One thing that was
available at the beginning of the Earth was time.”
A decade ago, this theory might have been dismissed because the early Earth
was thought to be so hot and volcanic that ice couldn’t form. But more recently
there has been evidence that the climate may have been more temperate, with
areas of ice on the poles and at high altitudes, Holliger said.
If the theory of an ice RNA world is correct, it could dramatically change our
search for life elsewhere in the universe.
“Ice is literally everywhere,” Holliger said . “If we can conceive of life
arising and maybe thriving in ice it would considerably broaden the places to
look for life, both extant and extinct.”
This water-color-esque image
captures hot stellar winds carving away at pillars of cold gas, like ice
sculptors wielding torches.
These one-light-year-tall pillars of cold hydrogen and dust are located 7,500
light-years away in the Carina Nebula. Violent
stellar winds and powerful radiation from massive stars are sculpting the
surrounding nebula. Inside the dense structures, new stars may be born.
