Tar Flower Found - Researchers using a robot to look
for underwater shipwrecks in the Gulf of Mexico have instead
stumbled upon some rare volcanic "Tar Flowers" on the ocean
bottom. The "flowers" found in 4,300 feet of water are the
result of hot tar from under the ocean floor that froze
when it entered the frigid water. As sections peeled back
they formed what looks like a giant flower with black petals.
The formations are about 20 feet in diameter and ten feet
tall. "To use a cliché, we know more about the moon than
we know about the deep oceans," said Gilbert Rowe, a regent's
professor in marine biology at the university. "The more
we look, the more weird features we find, and each of these
features is a separate habitat for the creatures that live
there." These formations are the first such found in the
area of the Northern Gulf and are about 150 miles from Galveston,
Texas.

Little Water Makes Things Go Easier - A study was published
online in the journal Physical Review Letters suggests
that the ancient Egyptians made the job of hauling huge
stone slabs across desert sands to build pyramids and temples
easier by using water. A drawing found at the tomb of Djehutihotep
shows a worker standing on the front of a sledge pouring
water over the sand just in front of it. To see if this
would really work researchers compared pulling a mini-sled
over dry sand to pulling one over wet sand. They found that
the difference in effort pull the sledge was significantly
reduced. The water makes the sand form a more solid surface
and keeps the sledge from sinking into it. "The water forms
liquid bridges that glue the sand grains together, as in
a sandcastle," study co-author Dr. Daniel Bonn, a professor
of physics at the University of Amsterdam.
Vatican
Church Gets New Lights - The famed Sistine Chapel in
Rome is getting cutting edge high-tech lighting designed
to both better illuminated the art on the church's walls
and ceilings better and preserve it from damage. Lighting
manufacturer Osram is in the process of installing 7000
LEDs in the chapel. The mix of light they generate has been
specially tuned to match the pigments in individual locations
making for better, brighter viewing. The LEDs also emit
no ultraviolet (UV) or infrared radiation which are the
frequencies that most damage paint pigments. Tests have
shown that under normal operating conditions of 50 lux or
less, the artwork on the chapel's walls should be safe for
at least 1000 years. The new lights should boost the illumination
by a factor of five to 10, while also reducing power consumption
for the Chapel by more than 60%.
More
Lines in Peru - Researchers have discovered rock lines
in Peru predate the famous Nazca Lines by centuries. The
famous Nazca Lines were built around 100 B.C., while the
new lines were found in the Chinca Valley, about 125 miles
(200 kilometers) south of Lima, Peru, and date back to 800
B.C.. While scientists still debate the purpose of the Nazca
Lines, team leader Charles Stanish, the director of the
Cotsen Institute of Archaeology at the University of California,
Los Angeles, believes the lines at Chinca were used as a
way to mark time during festivals. The areas includes not
just lines, but mound and piles of rock. Stanish said, "They
basically created these areas of highly ritualized processions
and activities that were not settled permanently." He likens
the activity to medieval fairs that brought visitors from
far and wide.
New
Record Dino Found - Paleontologists think they have
found "the big one" in the desert 135 miles west of Trelew,
Patagonia. It is a dinosaur 130 feet long with its head
the height of a seven story building. This newly discovered
sauropod (the planet-eating type of dinosaurs with four
legs and a long neck and tail) is a type of titanosaur that
lived in the Late Cretaceous period (95 and 100 million
years ago). The previous record holder was Argentinosaurus
which was found in the same region. Scientists think Argentinosaurus
weighed in at 70 tons, and this new unnamed dino at 77 tons.
It was first discovered by a local farm worker and then
excavated by a team of paleontologists from the Museum of
Paleontology.

All
Photons Look Alike? - If photons are all identical
how do they carry any properties of what they are reflecting
off of? - Gary
Well, let's start by defining what a photo is for readers
that don't know. A photon is a single packet of electromagnetic
(or light) energy. The actual term photon was coined by
Gilbert Lewis in 1926, but the idea of light in the form
of discrete particles had been around much longer.
Photons
are constantly in motion and in a vacuum travel at the colossal
speed of 186,000 miles a second (The speed of light). Another
interesting characteristic of a photon is that they are
both a particle and a wave at the same time.
Photons
are created when radiation is emitted from an object. For
example, heating a piece of metal till it glows is causing
the atoms in the metal to radiate photons (This is how an
incandescent lamp works). Photons can also be absorbed by
an object.
Now
to your question: How can all photons be identical to one
another? Well, they are in the sense that they are all made
of the same stuff, but that doesn't mean that a photon doesn't
also have properties that allow us to tell them apart. One
property that they have is the amount of energy they carry.
This is expressed in the frequency of their wave. To us
the wave frequency of a photon appears as its color. Low
frequencies are seen as the red end of the color spectrum
and high frequencies are seen as the blue end of the spectrum.
When
photons hit a green painted surface the photons that aren't
at the green frequency are absorbed while those with the
green frequency are reflected (which is why we see the surface
as green).
Another
property a photon can have how it is polarized. Photons
that are polarized vertically will not pass through a sheet
of glass or plastic that has a horizontal polarization.
(This is used in 3-D movies where the images going to your
right eye are polarized one way and images meant for your
left eye are polarized the other. You wear glasses with
each lens polarized a different way to filter out the unwanted
image).
Perhaps
a word picture will help. Imagine two identical cars driving
down a road at the same speed. One is has just come out
of the desert, however, and is really hot. The other just
came out of a freezer, so it really cold. Identical cars
traveling same speed, but they have different kinetic energy
levels. This might give them different behaviors too. Imagine
them hitting a wall made of ice very slowly, the hot one
might melts its way through while the cold one might just
bounce off.

History:
Lost
Opportunity to Find a Planet - On June 5th, 1819, John
Couch Adams was born. Adams, a common man, was able to use
mathematics to predict the existence of the planet Neptune
based on the way it's gravity was affecting the other planets.
Unfortunately because of his low ranking in society he could
not get anybody with a telescope to take his calculations
seriously and actually look to see if he was right. Because
of this French astronomer, Urbain Le Verrier, was able to
make the same calculations and beat Adams to the punch in
announcing the discovery of a new planet and embarrassing
the British. For more information on the search for planet
"X," check our page.

Meteors
Maybe? - Want to take a chance on viewing a somewhat
iffy meteor shower? June 27th marks the peak of the Boötids
shower. This meteor shower, the result of the Pons-Winnecke
comet, is known to occasionally have unexpected outbursts,
but is usually unspectacular. If you want to see if you
can catch some of these shooting stars start looking out
on the nights surrounding June 27th at the constellation
Boötid. One good thing is that there should be little moonlight
to interfere with viewing this year and these meteors usually
move slowly making them easier to spot

Santa
Maria Found? - Famed underwater explorer Barry Clifford,
who made a name for himself finding pirate wrecks, thinks
he may have found perhaps the most well-known shipwreck
of the them all: Christopher Columbus' flagship the Santa
Maria. Clifford first investigated the wreck back in 2003,
but only recently realized the significance of the cannon
he found there. The type of cannon he saw, a lombard, was
recorded by Columbus in his records as being carried on
his flagship ship. The Santa Maria sank on Christmas Day
in 1492 just off the coast of what is now known as Haiti
during Columbus' first voyage to the Americas. While Clifford
is sure of his find, proof may be difficult. The cannon
that is his "smoking gun" has been looted off the bottom
in the decade following his find. Clifford hopes to meet
with the Haitian government next month in preparation of
doing a full scale archeological dig to get at the truth.

I. This fascinating two-hour special tells the story of
Einstein's little-known, 15-year struggle to prove one of
his most radical theories -- a theory that upended Newton
and three centuries of scientific thought and called into
question the definitions of space and light and gravity
-- the game-changing concept known as the Theory of General
Relativity. Today, more than a century since the "Miracle
Year" in which he published many of his breakthrough papers,
Einstein's ideas remain a living, vibrant influence. They
continue to push scientists farther, and deeper, into the
universe than even he could have imagined. On the History
Channel: Sun June 1, 8:00 PM ET/PT.
