Ballard
Found Noah's Flood? - Dr Robert Ballard, discoverer of the Titanic,
has found the remains of settlements at the bottom of the Black Sea under
300 feet of water. These settlements were thought to have been covered
over some 7,000 years ago when the waters of the Mediterranean Sea overflowed
into the Black Sea causing an enormous flood. Some researchers have speculated
that the flood may be the one referred to in the Bible story of Noah's
ark.
NASA
Space Elevator - NASA scientists are starting to look at how a 'Space
Elevator' might be built. David Smitherman of NASA/Marshall's Advanced
Projects Office has compiled a publication called Space Elevators:
An Advanced Earth-Space Infrastructure for the New Millennium based
on findings from a conference last year. A space elevator would consist
of a long cable extending from Earth's surface to a space station in geostationary
orbit some 35,786 km overhead. Rather than using expensive rockets to
put people and materials into orbit, space elevators would climb the cable
at a fraction of the cost. Such a project is still beyond current technology,
but might be possible at the end of the century after new high-strength
materials are developed.
British
Scientists Warn of Asteroid Danger - Britain's Task Force on Near
Earth Objects reports the threat to Earth by a large asteroid hit
is very real and concludes the British government should take some steps
to prevent it. The Task Force recommends the development of an asteroid
early warning system using British telescopes. In response to the report
the minority Liberal Democrat Party called for 70 million pounds to be
spent over the next ten years on technology to track asteroids. Such a
system could give Earth a five to one-hundred year warning of such an
impact, therefore giving scientists a chance to design a system to divert
the asteroid before it hits.
Comet
Responsible for Dark Ages?- Professor Mike Baillie of Queen's University
in Belfast thinks that something very, very bad happened to the Earth
around 540 AD and whatever it was might be responsible for the end of
the Roman Empire and the beginning of the Dark Ages. Baillie bases his
theory on tree rings. Trees he has examined show a slow down of growth
at that time. Baillie thinks this was due to a bombardment of cometary
debris onto Earth. Many historians are reluctant to accept Baillie's idea
because no written records during that period tell of such an event, though
there are legends from that time telling of a comet that seemed to set
the sky on fire.
Early
Sauropod - Eric Buffeaut of France's National Center for Scientific
Research reports in an article in Nature that a sauropod dinosaur
skeleton has been discovered in Thailand. The bones are significant because
they date from the boundary of the Triassic/Jurassic period. Scientists
knew that sauropod dinosaurs, which have long
necks, long tails and four feet, lived in the Jurassic and Cretaceous
period, but this is the first evidence they also lived earlier in the
Triassic period. The animal discovered has been given the name Isanosaurus
attavipachi.
Moldy
Army Not Under Threat - Authorities have refuted earlier reports that
mold on China's 2,200-year old terra cotta army are causing them to decay.
The army of 8,000 life-sized figures of warriors and horses are part of
the tomb of China's first emperor, Qui Shihuang, who died in 210 BC. Officials
of the Terra Cotta Warriors and Horses Museum have said there is
"No danger" and that the blue, white and yellow-colored molds
were common at sites worldwide and did nothing to damage the famous statues.
The army, which was meant to protect the emperor in the afterlife, was
discovered in the 1970's by farmers digging a well and has become one
of China's top tourist attractions.
Lost
World found in Cambodia? - Scientists have identified a mountainous
region of Cambodia filled with previously unknown creatures and creatures
thought to be extinct. Jenny Daltry, a biologist, led an expedition sponsored
by Fauna and Flor International of Cambridge to this remote region
where they discovered the once thought extinct Siamese crocodile and also
the Wolf Snake. They found large numbers of frogs, moths and subspecies
of birds that are new to science. Scientists hope that the Cambodian government
will legally protect the area and preserve the wildlife.
