Moon is shrinking, say astronomers
WASHINGTON — The Man in the Moon has become the latest victim of contraction in the housing market.
Astronomers reporting on Thursday in the US journal Science said they had found previous undetected landforms which indicate that Earth's satellite has been shrinking... albeit by only a tiny amount.
The intriguing features, called lobate scarps, are faults created when the Moon's once-molten interior began to cool, causing the lunar surface to contract and then crinkle, they said.
Relative to the Moon's age, estimated at around 4.5 billion years, the contraction is recent, occurring less than a billion years ago, and is measured at about 100 metees (325 feet).
Lobate scarps were first spotted near the lunar equator in the 1970s by panoramic cameras aboard the Apollo 15, 16 and 17 missions.
Fourteen new faults have been been spotted in high-resolution images taken by NASA's Lunar Reconnaissance Orbiter.
The new discoveries show that the scarps are globally distributed and not clustered in equatorial regions, and this provides powerful evidence for the contraction scenario.
The investigation was headed by Thomas Watters of the Center for Earth and Planetary Studies at the Smithsonian Museum's National Air and Space Museum, Washington.

Nine, where'd u find that blood poster? I like it, except for the blood not being blue part. Once blood travels to your muscles it distributes oxygen so the deoxygenated blood does become a purplish color, (it seems blue to the eye bc of your skin and musculature) it then goes into the lungs and picks up oxygen becoming red arterial blood. Doctors have told me this, and even in my anatomy and physiology text says it. This is why lips turn blue when someone is choking, all that oxygenated blood in the numerous capillaries in your lips are no longer getting oxygen, so with every heartbeat it's replaced with the purple deoxygenated blood.
Everything else on that poster is awesome.

Biologist still consider the color you describe as a deep shade of red.
For many years biologist had the notion that blood was blue, as it appeared in veins, and that blue blood could not exist outside of the body while in an oxygen environment because the air would instantly turn the blood red (exposure to oxygen). Recently, 4 years ago to be more exact, a study was done which involved a series of complicated experiments, mostly on fresh bodies of pigs that still had an ample supply of blood and on fresh dead humans before their body fluids were drained (the humans were, of course, donating their bodies for the sake of science). The experiments involved consisted of extracting blood in an air tight environment so that venous blood could be seen in it's true colour. After several months of research, the results obtained stated that venous blood in a no-oxygen environment (or low oxygen so long as the supply of O2 in the air cannot fully meet the demand) would be a deep shade of red, almost purple. Arterial blood, or oxygenated blood, is bright red.
So why does venous blood appear blue?
Well for that you need to understand the structure of a vein. For those of you who have done dissections (and that may be the majority) you will notice that veins in many mammals similar to humans are milky white in colour and translucent. Veins also have blue pigments in the tissue. These pigments fade after death, however, and make it difficult to detect this. Visible veins are generally very close to the surface of the skin. As light shines through the skin, it enters the veins and is reflected by the blood. If the veins were clear tissue, we would see venous blood for the colour it really is. However, because of the milky tissue and blue pigments, the blood appears to be blue.
Philly requiring bloggers to pay $300 for a business license
It looks like cash hungry local governments are getting awfully rapacious these days:
Between her blog and infrequent contributions to ehow.com, over the last few years she says she’s made about $50. To [Marilyn] Bess, her website is a hobby. To the city of Philadelphia, it’s a potential moneymaker, and the city wants its cut.
In May, the city sent Bess a letter demanding that she pay $300, the price of a business privilege license.
“The real kick in the pants is that I don’t even have a full-time job, so for the city to tell me to pony up $300 for a business privilege license, pay wage tax, business privilege tax, net profits tax on a handful of money is outrageous,” Bess says.
It would be one thing if Bess’ website were, well, an actual business, or if the amount of money the city wanted didn’t outpace her earnings six-fold. Sure, the city has its rules; and yes, cash-strapped cities can’t very well ignore potential sources of income. But at the same time, there must be some room for discretion and common sense.
When Bess pressed her case to officials with the city’s now-closed tax amnesty program, she says, “I was told to hire an accountant.”
She’s not alone. After dutifully reporting even the smallest profits on their tax filings this year, a number — though no one knows exactly what that number is — of Philadelphia bloggers were dispatched letters informing them that they owe $300 for a privilege license, plus taxes on any profits they made.
Even if, as with Sean Barry, that profit is $11 over two years.
To say that these kinds of draconian measures are detrimental to the public discourse would be an understatement.

Mmm well that's good to know since I'll be teaching a whole chapter on blood in April. So where is the poster from? Sorry I'm on the phone and can't right click. Is it a poster? I would like to get that, even though I don't have one classroom,.... Ugh. Maybe not.

It says it's from onlineschools.org but I got it in an email.
Dozens of bones found in a 3,000-year-old archaeological site on Vanuatu [in the Pacific Islands] belong to a previously-undescribed species of meiolaniid, a turtle family that evolved 50 million years ago and resembled walking fortresses.
"This group of turtles is not known to have survived into the presence of humans. Now we can say that they met," said paleontologist Trevor Worthy of Australia's University of New South Whales.
The shell of one early meiolaniid species, known from fossils recovered in South America and named Stupendemys for its size, was 11 feet long and seven feet wide. The more modern Meiolania platyceps, found in Australia and Melanesia, had a relatively small five-foot-diameter shell, and weighed an estimated half-ton. All had armored club tails and horned heads.

Astronomers have discovered a planetary system containing at least five planets that orbit a star called HD 10180, which is much like our own Sun.
The star is 127 light years away, in the southern constellation of Hydrus.
The researchers used the European Southern Observatory (Eso) to monitor light emitted from the system and identify and characterise the planets.
They say this is the "richest" system of exoplanets - planets outside our own Solar System - ever found.
Christophe Lovis from Geneva University's observatory in Switzerland was lead researcher on the study. He said that his team had probably found "the system with the most planets yet discovered".

"This also highlights the fact that we are now entering a new era in exoplanet research - the study of complex planetary systems and not just of individual planets," he said.
http://www.bbc.co.uk/news/science-environment-11070991
The research has been submitted for publication to the journal Astronomy and Astrophysics.
Eso's High Accuracy Radial velocity Planet Searcher (or Harps) instrument was responsible for the discovery.

A new image taken by NJIT Distinguished Professor Philip R. Goode and the Big Bear Solar Observatory (BBSO) team is the most detailed sunspot photo yet. In September, the popular astronomy publication, Ciel et l’Espace will publish more photos of the Sun taken using BBSO’s new adaptive optics system.
Goode said that the images were achieved with the 1.6 m clear aperture, off-axis New Solar Telescope (NST) at BBSO. The telescope has a resolution covering about 50 miles on the Sun’s surface.
In the center is a dark sunspot, that is to say a colder zone, less brilliant than the rest of the solar surface. The temperature is around 3600 ° C. All around, the mosaic of small cells is called granulation (temperature: about 5800 ° C). On an average size of 1000 km, these cells are made of hot gas rising from inside the Sun.

FOGBOW SEASON BEGINS: Northern autumn is just around the corner, which means the time for fogbows has arrived. Moisture rising from the sun-heated ground condenses in the cool night air, producing low-hanging fogs. When light from the morning sun or Moon hits the mist--voil?*--a fogbow:
This is must be the most known picture in the Internet and in the whole world. The pictures depict American astronaut Bruce McCandless II who became the first to make an untethered spacewalk thanks to nitrogen jet propelled backpack called the Manned Maneuvering Unit (MMU) in 1984.
At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was further out than anyone had ever been before "free-flying" to a distance of 320 feet away from the Orbiter.
MMUs are no longer used due to security problems, but astronauts now wear a similar backpack device in case of emergency.

'Dry Water' Could Make a Big Splash Commercially, Help Fight Global Warming
ScienceDaily (Aug. 26, 2010) — An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming, scientists reported at the 240th National Meeting of the American Chemical Society.
Known as "dry water" because it consists of 95 percent water and yet is a dry powder. Each powder particle contains a water droplet surrounded by modified silica, the stuff that makes up ordinary beach sand. The silica coating prevents the water droplets from combining and turning back into a liquid. The result is a fine powder that can slurp up gases, which chemically combine with the water molecules to form what chemists term a hydrate.

You Swallow These Invisible Shrimp With Every Gulp of NYC Tap Water
New York's water is delicious—and filled with tiny crustaceans called "copepods". (Making it possibly not kosher.) H&E stain the water and put it under a microscope and you'll find these little guys.
Delicious!
(And completely harmless. Copepods are even known to eat mosquito larvae, so don't think of them as invisible shrimp that are caught in your teeth—think of them as invisible shrimp who make NYC tap water taste fantastic. Like fantastic, quenching shrimp juice.)
http://gizmodo.com/5626497/you-swallow-invisible-shrimp-with-every-gulp-of-nyc-tap-water
fuck. i feel ripped off drinking shitty clean water. why don't we have shrimps in our water?
Them shrimps make me glad I don't drink water. Or eat seafood of any kind.
