In the
News:
Giant Rock Threatens Earth... Maybe - Scientists are watching a large
asteroid to see if it will have a catastrophic collision with Earth in
2014. The object, designated "2003 QQ47," will be monitored over the next
few months so that astronomers can get a precise track of its orbit. With
that they will be able to predict its future movements. Estimates are
that its current chance of hitting Earth are just one in 909,000. Astronomers
believe that the chance of an impact should go down even further as better
data is collected. The asteroid, should it actually hit Earth, would produce
an explosion equivalent to 20 million Hiroshima atomic bombs, according
to a spokesman from the British government's Near Earth Object Information
Centre.
"Nefertiti"
Mummy Maybe Man - A mummy, tentatively identified last month as the
Egyptian Queen Nefertiti by Joann Fletcher, a mummification specialist
from the University of York in England, may actually be a man. Egypt's
antiquities chief Zahi Hawass has stated he is "sure that this mummy
is not a female." Hawass cites a double-piercing in the mummy's ear
as evidence of the gender of the remains. According to Hawass "queens
used to wear earrings in their wigs, not in their ears." Also, said
Hawass, it is known that Nefertiti gave birth six times so her hips should
be very broad. Hawass notes that the mummy in question has hips that are
very narrow. Professor Salima Ikram of the American University agreed
with Hawass noting that X-rays of the mummy do not show signs that the
person gave birth.
Scientists
Demonstrate "Haunted" Infrasound - Scientists in Manchester,
England, have demonstrated a connection between very low frequency sound
(infrasound) and unpleasant feelings in humans. The scientists produced
infrasound with a seven meter long pipe and tested its effect on 750 people
at a concert. Though the audience was not told which pieces included the
sound, twenty-two percent reported unusual feelings when it was included
in the music. The feelings included being uneasy, sorrowful, nervous,
revolted or fearful. "These results suggest that low frequency sound can
cause people to have unusual experiences even though they cannot consciously
detect infrasound," said Professor Richard Wiseman, a psychologist at
the University of Hertfordshire. Some scientists propose that naturally
occurring infrasound may be present at locations that are considered "haunted."
A
3/4 Ton "Guinea Pig" Discovered in South America - Researchers
say they have found the remains of a rodent the size of a buffalo in South
America. Fossils suggest a 1,545-pound rodent that was a plant eater lived
6 million to 8 million years ago in what was then a lush, swampy forest.
Marcelo R. Sanchez-Villagra of the University of Tubingen in Germany described
the creature as "...a weird guinea pig... with a long tail for balancing
on its hind legs..." The fossils where found in a desert area some
250 miles west of Caracas, Venezuela. The official name of the rodent
is Phoberomys pattersoni, though the paleontologists have nicknamed
this particular specimen "Goya."
Spanish
Navy Takes Heat for Squid Deaths - Four giant
squid, the largest of which was 12 meters (almost 40 feet) long have
died in the waters off the coast of Spain in recent weeks. Giant squid
are seen rarely because they live at such great depths. Environmentalists
are blaming the Spanish Navy, and in particular the ship Hesperides
for the deaths. The Hesperides has been testing systems that create
underwater shock waves for purposes of mapping the ocean floor. Josep
Gallard, a leading scientist working on the ship, denied that this is
harmful to the squids. "This hypothesis is far from being proven,"
said Gallard.

Ask the
Curator:
The
Face of King Tut - Its said that there are methods of putting together
a sculpture or "mask" of what an Egyptian looked like. Is this true? If
so, has this method been used to recreate a possible image of what the
young King Tutankhamen might have looked like? If it has been used is
there a website or place that I can see a picture of this? -Lori
Dr Robin Richards, a facial-reconstruction
expert from the Department of Medical Physics and Bioengineering University
College London, has recreated Tut's face by using CAT scans of X-rays
of the mummy to create a 3D representation of the King's skull in a computer.
From there digital skin and other features can be laid on top of the skull.
The method is very similar to that used by forensic experts for reconstructing
a face from a skull found in connection with a crime. The digital image
was later made into a sculpture for the UK Science Museum. For a more
complete explanation of the process and some pictures, check out these

Mars
Orbits - How does one calculate that Mars is closer to Earth
than it has been for 60,000 years? - Paul Kalmen
The first step to knowing the
position of the planets is to observe them in the sky and work out their
orbits. Much of the grunt work for this was done in 16th century by Tycho
Brahe though many nights of staring at the sky and making notes. Tycho
thought that planet orbits must be circular but he couldn't get his theory
to jive with his observations. Johannes Kepler took Tycho's data and realized
that the planets orbits must be slightly elliptical. With this Kepler
was able to come up with his Laws of Planetary Motion.
The laws basically state how
the planets move though space based on attraction by gravity to the sun
and each other. Put the laws into a computer and you can then use them
to predict the relationship of the planets to each other at any future
or past time, though accuracy starts to break down as you move further
away from the present period. Still, in the history of the solar system
60,000 years is a fairly short period, so the estimated positions of the
planets should be pretty accurate.
Supporters of Velikovsky's
theories might argue that the planets have been moving around the
solar system out of their orbits in recent history, but most scientists
don't think there's any evidence to support his hypothesis.
