Scientists Recreate Ancient Rome - A group of
researchers spearheaded by the Institute for Advanced Technology in the
Humanities at the University of Virginia have re-created ancient Rome
inside a computer. The project, named "Rome Reborn 1.0" allows virtual
time travelers to walk through the ancients streets of the city as if
they were there in June 320 A.D.. The computer model allows visitors to
navigate with complete freedom, moving up, down, left and right at will.
They can enter important public buildings such as the Roman Senate House,
the Coliseum, or the Temple of Venus and Rome, the ancient city's largest
place of worship. The location and appearance of the buildings is based
on archeological data gathered by scientists over the past five centuries.
Diane Favro, a founder of the project said, "This amazing model allows
us to appreciate individual buildings of ancient Rome within a broad urban
context, and thus also to understand how the modern city took shape over
time." Video clips and still shots of the model can be viewed at http://www.romereborn.virginia.edu.
Dinos Probably Contorted by Death - Fossilized
dinosaurs that have died with their mouths wide-open, heads thrown back
and tails that curved toward the head may be showing signs of asphyxiation
and brain damage. Scientists have long thought that these dinosaurs had
died in water and the currents pushed the bones into that position, or
that rigor mortis contorted the body. "I'm reading this in the literature
and thinking, 'This doesn't make any sense to me as a veterinarian,'"
said Cynthia Marshall Faux, a veterinarian-turned-paleontologist at the
Museum of the Rockies. Faux thinks that animals found in this posture
may have suffocated in ash during a volcanic eruption or may have been
contorted at death by disease, brain trauma, severe bleeding, thiamine
deficiency or poisoning. One interesting observation is that modern animals
found in this posture during death are almost those with high metabolic
rates, giving support to the idea that dinosaurs were warm blooded animals.
Weapon Found in Whale Dates from 1800's - The
tip of a lance over a hundred-years-old was found in the shoulder of a
50-ton bowhead whale caught off the Alaska. The weapon, used to hunt whales
around 1890, was launched from a heavy shoulder gun. Finding this object
buried deep in the whales blubber allows scientists to get a better fix
on how long whales can live. The 3½-inch arrow-shaped projectile is estimated
between 115 and 130 years old. Scientists' think that this means the whale
was at least 130-years-old. Researchers were unaware of exactly how long
a bowhead whale could live, but other species of whale are estimated to
be able to survive up to centuries in rare cases.
Ancient People Ate On-the-Run - A new study shows
that the ancient residents of Pompeii may have a lot in common with today's
families as far as eating fast food goes. According to archaeologist Penelope
Allison of the University of Leicester, the majority people in the city
ate "on the run." She noticed that may middle-class households in the
ancient city lack of tableware and a formal dining or kitchen areas. Instead
her examination found plates here and there around the household, such
as in the sleeping quarters. "Similar to how children today bring a plate
of food to their rooms before watching TV or playing on the computer,
my guess is that Roman youths would tote food to certain areas where they
possibly engaged in other activities," she said.
Mickey Back to the Future? - In a dig in Uppåkra
in Sweden scientists have discovered a thousand year old bronze brooch
that looks a lot like it should have been sold at a gift shop in Disney
World. The object, which most likely was worn on the clothing of an Iron
Age woman, bares a remarkable resemblance to Mickey Mouse. Is this a case
of a modern souvenir falling into a time-warp? No, according to archaeologist
Jerry Rosengren from Lund University the jewelry most likely supposed
to represent a lion. Lions were important symbols to royals and warlords,
said Rosengren, especially after Christianity was introduced to the Scandinavia.
The broach was likely created by a French artist, who probably never had
seen a lion in his entire life and came up with a fantasy version.

Ask the
Curator:
Before Big Bang - I'm a 60 year old scientist
and I have a rock-solid understanding of the concept of entropy, including
the idea of life as a temporary bump in the overall decline of order and
organization in a system. All I want before I die is to know if there
is any credible scientific theory about how the spring originally got
wound 14-or-so billion years ago - Bob W.
Let me re-phrase you question
as, "What was there before the Big-Bang and where did all the energy it
requires come from?" At this point I don't believe there are any "credible"
theories to explain this as none of the ideas scientists have about this
area can be tested by experimentation. In fact, there is not likely to
be anything testable until scientists can first create a Grand Unified
theory of everything combining Einstein's General Relativity with
Quantum Physics. That quest, which has been pursued by physicists
like the Holy Grail for almost a century, so far does not seem near a
conclusion.
So the best I can do is to
throw out one of the more intriguing ideas floating around cosmology circles
these days. This particular model comes out of string theory (One possible
candidate for the Grand Unified Theory that says all energy and matter
is composed of super-small vibrating loops of strings.) This idea was
worked out by Paul Steinhardt (Princeton University) and Neil Turok (Cambridge
University). They suggest our universe is part of a much larger universe.
The model says that our universe exists on a three dimensional membrane
( or "Brane" in string theory lingo) and there are other branes close
to ours, only millimeters away, but invisible.
Every trillion years or so
these branes are drawn together and when they collide a huge amount of
energy is released making a "Big Bang" that creates a universe on the
brane (other universes can be created at other locations of the brane
that may collide at other times) This process of collision Steinhardt
and Turok named ekpyrosis which is the Greek word for conflagration.
In addition to creating a smaller universe, ekpyrosis also pushes the
branes apart.
Over the life of the universe
some of the big bang energy turns into matter which becomes stars, galaxies
and, of course, us. Eventually the energy involved in our universe spreads
out as stars burn out and the universe grows cold. According to this idea,
however, the branes which still contain the energy, and they are drawn
back together again to collide and create another universe in an eternal
cycle.
They only problem with this,
and alternate theories like it, is that there is no way to test these
theories experimentally to know if there is any evidence that they are
true. Even if this idea is true, however, we may have just moved the question
back a little bit further: What created that greater universe and where
did all its energy come from?
