The Giant Jellies are Coming!

(CNN) -- Giant jellyfish descend on the Sea of Japan, causing untold devastation to coastal villages and leaving a trail of destruction and human misery behind

A diver attaches a sensor to a Nomura's jellyfish off the coast of northern Japan in October 2005.

Sounds like a great sci-fi flick. But it's not.


It's real and a nightmare for Japanese fishermen.


The massive sea creatures, called Nomura's jellyfish, can grow 6 feet (1.83 meters) in diameter and weigh more than 450 pounds (204 kilos). Scientists think they originate in the Yellow Sea and in Chinese waters. For the third year since 2005, ocean currents are transporting them into the Sea of Japan.

Monty Graham, a marine biologist at Alabama's Dauphin Island Sea Lab, said the jellyfish grow to an enormous size as they are transported by ocean currents. He said they stay together in packs and as they drift northward, they get caught in fishermen's nets.

The giant jellyfish are one of about 200 species of coastal jellyfish or large jellyfish that exist around the world. But Nomura's stands out because of its enormous size.


"The sheer size of them, individually, makes them fairly spectacular," Graham said. Spectacular, perhaps, to scientists, but perilous to villagers along the Japanese coast who have seen the destructive habits of these colossal creatures in the past. They had giant-jellyfish invasions in 2005 and 2007, and because they've recently been spotted in the Sea of Japan, they're bracing for another, potentially harmful wave this summer.


The jellyfish destroy fishermen's nets, getting trapped in them, tearing holes and ruining catches.


Fishermen often use expensive mazelike nets that stretch for hundreds of kilometers. When swarms of giant jellyfish tear them, the result is devastating.


"Communities of fishermen and these fishing villages own these nets," Graham said. "When these nets get wiped out, it actually has this economic devastation for an entire community."


The good news is that previous attacks have prompted Japan to put in place a warning system for fishermen. While they still risk losing a big catch, they can, at least, save their pricey nets from the invasion of the giant jellyfish.


It's not clear why waves of Nomura's jellyfish have made it to the Sea of Japan in recent years. Some have speculated that overfishing, pollution or rising ocean temperatures may have depleted the kinds of fish that prey on Nomura's jellyfish in the polyp stage. However, no one is certain, Graham said.

Sep. 29, 2009 (GlobeNewswire) --

NORWALK, Conn., Sept. 29, 2009 (GLOBE NEWSWIRE) -- The Northrop Grumman (NYSE:NOC) Foundation sent 30 educators representing various school districts throughout Connecticut, Maine, New Hampshire, New Jersey, New York and Rhode Island into weightlessness today as part of the Northrop Grumman Foundation Weightless Flights of Discovery Program, which aims to inspire and prepare the next generation of scientists, mathematicians and engineers -- critical areas where the U.S. has fallen behind globally.


As the plane flew over the waters of the Atlantic Ocean, teachers conducted a range of experiments, including soaring like Superman, as they experienced lunar, Martian and zero gravity. Pictured: James Janski, Wells Road Intermediate School, Granby, CT (top row, left); Geoffrey Bergen, Whisconier Middle School, Brookfield, CT (top row, right); Michael Gary, J. A. DePaolo Middle School, Southington, CT (second row, right); Nina Rooks Cast, Cooley Health, Science, Technology High School, Providence, RI (second row, left), and Brian Katz, Keansburg High School, Keansburg, NJ (bottom row, left).
The program, in its fourth year, provides educators with a once-in-a-lifetime opportunity to prepare for and participate in micro- and zero-gravity flights during which they test Newton's Laws of Motion with a variety of planned experiments. The experience and experiment results are captured through photos and videos that the teachers will then take into their classrooms to share with their students in order to demonstrate how exciting and cool careers in science, technology, engineering and math (STEM) can be.

The United States is experiencing a shortage of college graduates in the STEM disciplines, a negative trend that bodes ill for the nation's industries that depend on talented scientists and mathematicians. Because studies have indicated most children make the decision to pursue math and science education and careers during middle-school, Northrop Grumman developed the Weightless Flights of Discovery to engage teachers, and key influencers in the lives of students during these crucial years.

The Northrop Grumman Foundation supports diverse and sustainable programs for students and teachers. These programs create innovative education experiences in science, technology, engineering and mathematics.

The Nose Knows [more about Tycho Brahe ... a very odd man ...]

This story is directly from Curious Expeditions.



It was a precious metal occasion, Tycho thought to himself, looking down at his metallic options. Though heavier and more uncomfortable then the copper design, the gold and silver model looked more realistic and carried a certain gravitas and nobility. Today was a worthy event.

With that Tycho Brahe spread a layer of adhesive putty on the hole in his face where his nose used to be and smushed on the shiny metal nose, holding it in place to let it bond. The gold and silver had been mixed together to provide a somewhat flesh-like appearance, though Tycho knew it must have been distracting when it caught the light glinting off of it at odd angles. Tycho, however, was not one to let public opinion get to him. In fact, the metal nose on his face was one of the more normal things about Tycho Brahe.

Born in 1546 into Danish nobility, Tycho was a precocious child. Raised by an aunt and uncle, Tycho became fascinated with astronomy at the young age of 14 after he witnessed a solar eclipse. Amazed by both the event and the magical ability of the local astronomers to predict such an astonishing thing, Tycho took to astronomy like a fish to the sea. At the age of 17 he was already aware of the need for much more accurate astronomy practices, saying

“What’s needed is a long term project with the aim of mapping the heavens conducted from a single location over a period of several years.”

He did just that. Without the aid of the yet to be invented (or at least used for astronomy) telescope, Tycho worked night after night with only his eyesight and the best measuring instruments he could invent or acquire. Slowly he began the arduous process of making some of the very first accurate astronomical measurements.

Despite being obsessively accurate in his astronomical work, Tycho also knew how to let his mustache down. At the age of 20, Tycho was at a party when he got into a argument over mathematics and engaged in the very unwise idea of a duel in the dark. He escaped with his life but without his nose. Out of necessity he developed an immediate interest in metallurgy and crafted himself a metal replacement.

A wildly rich man (said to have owned as much as one percent of Denmark’s entire wealth at one point) Tycho also drank like a champ. He kept a future telling dwarf named Jepp around, often stashing him under the table during dinner. He also had a tame moose that he brought to friends houses for parties. Unfortunately at one such party, the moose was allowed to drink a large amount of beer and become highly intoxicated. It drunkenly fell down the stairs, and died shortly thereafter. If that’s not a wild party, I don’t know what is.

tychotomb.jpg Like a 16th century Animal House, this raucous behavior and Tycho’s general attitude towards the Danish peasantry was to eventually get him kicked out of Denmark. He settled himself in Prague where he got along with Emperor Rudolf II famously. Rudolf himself had a number of odd interests, and kept a beloved pet tiger. It’s not hard to see why they hit it off. Tycho was to be assisted in Prague by a young astronomer named Johannes Kepler. This, according to some, may have proved fatal.

Tycho sat down at the banquet that day, his precious metal nose weighing heavily on his face, unaware that this would be the last meal he ever ate. He felt ill throughout the banquet, but refused to leave the table, as it would have been poor manners. Tycho lapsed into a fever after the banquet and died 11 days later saying he words “Ne frustra vixisse videar” or “May I not seemed to have lived in vain” over and over.

The official story of his death, one corroborated by his assistant Kepler, was that he had strained his bladder by not using the bathroom during the banquet, and that did him in. But according to “Heavenly Intrigue: Johannes Kepler, Tycho Brahe, and the Murder Behind One of History’s Greatest Scientific Discoveries” Kepler would have had every reason to espouse this theory. After performing tests on Tycho’s hair, Joshua and Anne-Lee Gilder found that Tycho had very high mercury levels in his body. They claim in their book that Kepler, who went on to use Tycho’s research to write his own astronomy hit, “Laws of Planetary Motion”, had every reason to off Tycho and did so with a heavy dose of Mercury poisoning.

While it may be true that Kepler had a motive, the mercury levels in Tycho’s body are hardly solid evidence of murder. A serious practicer of alchemy, mercury exposure was a part of the job. Robert Hooke and Sir Issac Newton would both likely test well above Tycho for mercury levels. While Kepler may or may not have been a murderer, he certainly benefitted from his relationship with Tycho and Tycho’s untimely death. Two days after Tycho died, Kepler was appointed his successor as imperial mathematician.

All of which leaves me with one burning question. What’s the point of having a future telling dwarf named Jepp you keep under the dinner table, if he’s not around when you really need him?

Today one can see Tycho’s grave in the “Church of Our Lady in front of Týn” in the Old Town Square in Prague. Above his grave stands an relief of Tycho where one can just make out a line where the sculptor subtly indicated his metal nose.

Polish tests 'confirm Copernicus'

Researchers in Poland say they have solved a centuries-old mystery and identified the remains of astronomer Nicolaus Copernicus.
(click on image to see it enlarged)
A comparison of DNA from a skeleton in Poland and strands of the astronomer's hair found in a book in Sweden almost certainly confirm it is his skeleton.

Archaeologists found the skeleton in north-eastern Poland three years ago in a cathedral where Copernicus lived.


He worked in Frombork Cathedral on the Baltic Sea coast in the 16th Century.

Copernicus made the key scientific discovery that the Earth orbits the Sun.

For many years he was a canon and only carried out his astronomical studies in his spare time. People had speculated about his final resting place for centuries.

Teeth DNA

Three years ago, archaeologists dug up a skull and partial remains of a man aged about 70, Copernicus' age when he died, near an altar at the cathedral.

Jerzy Gassowski, the leader of the archaeologists' team, said forensic facial reconstruction of the skull found that it bore a striking resemblance to existing portraits of the father of modern astronomy.

Scientists then matched the DNA from one of the skull's teeth and a femur bone with two strands of Copernicus' hair.

The hair was found in a book once owned by the astronomer now kept in Sweden's Uppsala University.

Sea Potatoes -- a vacation find!


When I was in Cape Cod last week, I kept seeing these little Styrofoam-like "eggs" on the beach. They are about 4 inches long and fairly hard. I have been going to the Cape since I was a child, and I have never seen/noticed these things before. I asked the ranger at the Visitor Center, and she said they are brown algae; I broke one apart to see the insides and to take a whiff. They are definitely plant-like, that is true. They are like hardened foam on the outside, spongy green on the inside. The smell is a bit like low tide; not horribly unpleasant, but very biological.




I did a hurried web search to read up on them; I discovered their Latin name (Leathesia difformis) and also that there is a second "sea potato" that is actually a species of urchin. So much for common names (thanks again for the binomial nomenclature, Linnaeus!).


But I am left deeply unsatisfied with the information out there on the web about these objects. I want to know why the brown alga creates this structure and why there suddenly seem to be so many more of them. Do they bunch together like this in response to some sort of environmental stresses, or do they naturally grow like this? I must research further.

... or how about if we each boiled our bucket until it evaporated?!?

This Week's Sky at a Glance

From Sky & Telescope:


Some daily events in the changing sky for October 3 – 11.

Watch the Moon wax in the west from night to night, passing Venus and fainter Antares. (These scenes are drawn for the middle of North America. European observers: move each Moon symbol a quarter of the way toward the one for the previous date. For clarity, the Moon is shown three times actual size.)

Monday, October 6
Get a low-power scope onto Venus low in the west-southwest as twilight fades, and look for the wide double star Alpha Librae less than 1° to its north (upper right). This direction is correct at the time of twilight in North America. Venus itself is tiny (13″ wide) and gibbous.
Jupiter is the thing shining above the Moon this evening. Jupiter is now at eastern quadrature, 90° east of the Sun.

Tuesday, October 7
First-quarter Moon (exact at 5:04 a.m. EDT). This evening, Jupiter shines to the Moon's right.

Wednesday, October 8
Jupiter's moon Io emerges out of eclipse by Jupiter's shadow around 9:47 p.m. EDT, just east of the planet. A small telescope will show it gradually swelling into view.

Thursday, October 9
Early Friday morning, telescope users along the East Coast from Labrador to Florida can watch for whether the faint asteroid 225 Henrietta will occult (cover) a 10.4-magnitude star near the head of Cetus (not in Monoceros; that was an error).

Friday, October 10
The red long-period variable star W Lyrae should be about at its peak brightness (8th magnitude) this week.

Saturday, October 11
Jupiter's moon Ganymede disappears into eclipse by Jupiter's shadow around 9:39 p.m. Pacific Daylight Time, a little east of the planet. A small telescope will show it gradually fading away.

Cool.

This widely circulated new photo shows a Air Force F-22 Raptor aircraft participating in an exercise in the Gulf of Alaska June 22, 2009 as it executes a supersonic flyby over the flight deck of the aircraft carrier USS John C. Stennis.

The visual phenomenon, which sometimes but not always accompanies the breaking of the sound barrier, has also been seen with nuclear blasts and just after space shuttles launches, too. A vapor cone was photographed as the Apollo 11 moon-landing mission rocketed skyward in 1969.

I Won!


I don't know if you can tell, but in this picture I am trying really hard not to cry. I'm the cutie on the right with the jaunty neckerchief and the new glasses. I have just completely embarrassed myself, and winning third place is no consolation. Even when I take my prize coupon to McDonald's and get my free burger a few weeks later, its taste is bitter and rank with shame.

Everything was going fine, and then I got cocky. I breezed through all the words they threw at me, and by the way, did I mention I was a fourth grader at the fifth grade spelling bee? Seems like the town newspaper left out that important detail. Hmph! I am in the big league now!!!

I cranked out all these hard words: Ridiculous, neighbor, phrase. Then came my death-knell: Scissors. I know how to spell it, really I do. But you would never have known it by the way I reeled out the letters at lightning speed:

S--C--I--R--R--O--R--S. Scissors!

The look of horror on my mother's face in the audience instantly told me I had blown it, but I had no idea how. What did I say?!?!?! Her mouth agape, her eyebrows fixed in a frown of dismay ... that look is forever burned in my brain. I felt a flush begin at my heart and rush upwards to color my face and force its way out of my eyes as I listened to the second-place winner next to me recite the proper spelling. She fell shortly thereafter, but there was no joy in her fall for me, the loser who substitutes R's for S's.

Later, during our press photo, I tried to smile but the corners of my mouth did that funny little dance that they do when you have been smiling too long, as I fought to keep my tears and my choking sobs inside. On the drive home I listened to the consolations and teachings of my parents, and carried the lesson about "taking my time" into my bedroom, where I flopped onto the bed and cried, with visions of double S in my mind.

In later years, I would brag to others that I had "won" the town spelling bee. Nobody seemed to remember the truth, and I felt that my fall was really just a technicality, after all. I knew how to spell both of the words that came after "scissors," so if I hadn't rushed through that one I probably would have won. This was my mantra through middle school and even into high school. But I never ate a McDonald’s hamburger again without visualizing that word and tasting the salt of my own tears.

World's Largest Vacuum Chamber


World's Largest Vacuum Chamber

The Space Power Facility at NASA Glenn Research Center's Plum Brook Station in Sandusky, Ohio, houses the world's largest vacuum chamber. It measures 100 feet in diameter and is a towering 122 feet tall. The facility is currently undergoing construction to support Orion crew exploration vehicle testing in 2010.

Making its first flights early in the next decade, Orion is part of the Constellation Program to send human explorers back to the moon, and then onward to Mars and other destinations in the solar system. Orion also will carry crew and cargo to the International Space Station.

2 big satellites collide 500 miles over Siberia


AP Associated Press:

NASA said it will take weeks to determine the full magnitude of the crash, which occurred nearly 500 miles over Siberia on Tuesday.

"We knew this was going to happen eventually," said Mark Matney, an orbital debris scientist at Johnson Space Center in Houston.

NASA believes any risk to the space station and its three astronauts is low. It orbits about 270 miles below the collision course. There also should be no danger to the space shuttle set to launch with seven astronauts on Feb. 22, officials said, but that will be re-evaluated in the coming days.

The collision involved an Iridium commercial satellite, which was launched in 1997, and a Russian satellite launched in 1993 and believed to be nonfunctioning. The Russian satellite was out of control, Matney said.

The Iridium craft weighed 1,235 pounds, and the Russian craft nearly a ton.

No one has any idea yet how many pieces were generated or how big they might be.

"Right now, they're definitely counting dozens," Matney said. "I would suspect that they'll be counting hundreds when the counting is done."

As for pieces the size of micrometers, the count will likely be in the thousands, he added.

There have been four other cases in which space objects have collided accidentally in orbit, NASA said. But those were considered minor and involved parts of spent rockets or small satellites.

Nicholas Johnson, an orbital debris expert at the Houston space center, said the risk of damage from Tuesday's collision is greater for the Hubble Space Telescope and Earth-observing satellites, which are in higher orbit and nearer the debris field.

At the beginning of this year there were roughly 17,000 pieces of manmade debris orbiting Earth, Johnson said. The items, at least 4 inches in size, are being tracked by the U.S. Space Surveillance Network, which is operated by the military. The network detected the two debris clouds created Tuesday.

Litter in orbit has increased in recent years, in part because of the deliberate breakups of old satellites. It's gotten so bad that orbital debris is now the biggest threat to a space shuttle in flight, surpassing the dangers of liftoff and return to Earth. NASA is in regular touch with the Space Surveillance Network, to keep the space station a safe distance from any encroaching objects, and shuttles, too, when they're flying.

"The collisions are going to be becoming more and more important in the coming decades," Matney said.
