Paleolithic Bone Flute Discovered: Earliest Musical Tradition Documented In Southwestern Germany

Researchers in Germany have unearthed new evidence for Paleolithic music in the form of the remains of one nearly complete bone flute and isolated small fragments of three ivory flutes. The discovery suggests the musical tradition was well established when modern humans colonized Europe over 35,000 calendar years ago.

Excavations in the summer of 2008 at the sites of Hohle Fels and Vogelherd produced the new evidence. The most significant of these finds, a nearly complete bone flute, was recovered in the basal Aurignacian deposits at Hohle Fels Cave in the Ach Valley, 20 km west of Ulm. The flute was found in 12 pieces. The fragments were distributed over a vertical distance of 3 cm over a horizontal area of about 10 x 20 cm. This flute is by far the most complete of all of the musical instruments thus far recovered from the caves of Swabia.

“These finds demonstrate the presence of a well-established musical tradition at the time when modern humans colonized Europe, more than 35,000 calendar years ago,” the authors write in the journal Nature. “Other than the caves of the Swabian Jura, the earliest secure archaeological evidence for music comes from sites in France and Austria and post-date 30,000 years ago.”

‘Misty caverns’ on Enceladus moon

Nasa’s Cassini spacecraft has obtained strong evidence that Saturn’s tiny moon Enceladus retains liquid water.

The probe has detected sodium salts in the vicinity of the satellite, which appear to spew from its south pole.

Liquid water that is in prolonged contact with rock will leach out sodium – in exactly the same way as Earth’s oceans have become salty over time.

Scientists tell Nature magazine that the liquid water may reside in caverns just below the surface of the moon.

If confirmed, it is a stunning result. It means the Saturnian satellite may be one of the most promising places in the Solar System to search for signs of extraterrestrial life.

“We need three ingredients for life, as far as we know – liquid water, energy and the basic chemical building blocks – and we seem to have all three at Enceladus, including some fairly complex organic molecules,” commented John Spencer, a Cassini scientist from the Southwest Research Institute, Boulder, Colorado.

“That’s not to say there is life on Enceladus but certainly the ‘feedstock’ is there for life to use if it does exist,” he told BBC News.

Scientists have been looking for sodium near Enceladus since the discovery in 2005 that this 500km-wide moon was active and hurling water vapour and ice particles into space.

The vapour and ice particles emerge in super-fast jets from a series of “warm” surface cracks referred to as “tiger stripes” because of their resemblance to the big cat’s coat markings.

Researchers speculated that the jets could be being fed by a large sub-surface body of liquid water, even an ocean. But the best indicator remained frustratingly elusive.

If it existed, such a mass of water in contact with rock deep within Enceladus would acquire a range of dissolved salts over time and these ought to be detectable in the jets by Earth telescopes.

Indeed, sodium (which in Earth’s oceans forms the dominant sea salt, sodium chloride) is one of the easiest elements for observatories to spot in space.

However, even mighty telescopes like the Keck on Mauna Kea in Hawaii could never see sodium when they looked towards Enceladus.

The latest Cassini data appears to solve this conundrum.

The Nasa spacecraft has been flying through Saturn’s outer E ring which is sustained by the constant stream of material coming up from the tiger stripes.

Using its Cosmic Dust Analyser (CDA), Cassini has analysed thousands of ice grains and directly “tasted” the missing salt – principally sodium chloride and sodium bicarbonate (“baking soda”).

The amounts, though, are tiny – less than 2% of the mass of the sampled grains.

The low abundance helps explain why the telescopes had overlooked the salt. The fact that the sodium is bound into the water-ice molecules also effectively hides its light signature from the observatories’ instruments.

However, scientists say the Cassini and telescope observations taken together give hints about what the water reservoir on Enceladus might look like.

‘Ark of the Covenant’ about to be unveiled? (Update: No, it isn’t.)

The patriarch of the Orthodox Church of Ethiopia says he will announce to the world Friday the unveiling of the Ark of the Covenant, perhaps the world’s most prized archaeological and spiritual artifact, which he says has been hidden away in a church in his country for millennia, according to the Italian news agency Adnkronos.

Abuna Pauolos, in Italy for a meeting with Pope Benedict XVI this week, told the news agency, “Soon the world will be able to admire the Ark of the Covenant described in the Bible as the container of the tablets of the law that God delivered to Moses and the center of searches and studies for centuries.”

The announcement is expected to be made at 2 p.m. Italian time from the Hotel Aldrovandi in Rome. Pauolos will reportedly be accompanied by Prince Aklile Berhan Makonnen Haile Sellassie and Duke Amedeo D’Acosta.

“The Ark of the Covenant is in Ethiopia for many centuries,” said Pauolos. “As a patriarch I have seen it with my own eyes and only few highly qualified persons could do the same, until now.”

“Dog-kangaroos” turn heads in the Philippines

Dog lovers, meet Cute and Bambi, who have been dubbed “dog-kangaroos” by those who have encountered the pair in Quezon City, Philippines.

Cute and Bambi were apparently both born with only their two rear legs and are the pets of Lope Tulipas, a Quezon City street vendor. Many passersby are understandably taken by the pair — some have even offered to buy them, but Tulipas has turned down all offers.

Dead Sea peril: sinkholes swallow up the unwary

Eli Raz was peering into a narrow hole in the Dead Sea shore when the earth opened up and swallowed him. Fearing he would never be found alive in the 30-foot- deep pit, he scribbled his will on an old postcard.

After 14 hours a search party pulled him from the hole unhurt, and five years later the 69-year-old geologist is working to save others from a similar fate, leading an effort to map the sinkholes that are spreading on the banks of the fabled saltwater lake.

These underground craters can open up in an instant, sucking in whatever lies above and leaving the surrounding area looking like an earthquake zone.

The phenomenon, Raz said, stems from a dire water shortage, compounded in recent years by tourism and chemical industries as well as a growing population. “This is the most remarkable evidence of the brutal interference of humans in the Dead Sea,” he said.

The parched moonscape, famous as the site of biblical Sodom and Gomorra, is the lowest point on earth and runs more than 60 miles through Israel and the West Bank.

Large sections of the coast are fenced off and signposted in Hebrew and English: “danger, open pits” and “sinkhole area ahead.” But it’s too expensive to inspect every place for danger. Just two months ago an Israeli hiker wandered into an area that had no warning signs and was critically injured when he fell into a sinkhole.

While such accidents are rare, Raz says there are up to 3,000 open sinkholes along the coast and likely just as many that haven’t burst open yet. And they’re having a big impact on Israeli development plans.

The collapsing terrain has forced authorities to close a campground, date groves and a small naval base, and to scrap plans for 5,000 new hotel rooms, said Galit Cohen, director of environmental planning at the Ministry of the Environment.

The holes, also found on the Jordanian side of the sea, are the result of the Dead Sea having shrunk by a third since the 1960s when Israel and Jordan built plants to divert water flowing through its main tributary, the Jordan River.

The holes form when a subterranean salt layer that once bordered the sea is dissolved by underground fresh water that follows the receding Dead Sea waters.

Charlie’s Angels pin-up actress Farrah Fawcett dies

Charlie’s Angels star Farrah Fawcett today lost her two-year battle with cancer.

The 62-year-old actress, who became an icon to millions during the 1970s, died in a hospital in Los Angeles surrounded by her family and friends.

A devout Catholic, the Charlie’s Angels star was read the last rites this morning.

It had been her last wish to marry actor Ryan O’Neal, who she had a son with during a stormy relationship that lasted for 27 years.

But the wedding was unable to take place due to the amount of medical care she needed.

The couple had been waiting months for her condition to improve in hospital to go through with the bedside ceremony.

O’Neal, 68, was at her side throughout her final days and was seen leaving the hospital this morning in tears.

Asked how he was, he quietly replied: ‘No, I’m not ok,’ before walking to his car and driving away.

In a statement O’Neal said: ‘After a long and brave battle with cancer, our beloved Farrah has passed away.

‘Although this is an extremely difficult time for her family and friends, we take comfort in the beautiful times that we shared with Farrah over the years and the knowledge that her life brought joy to so many people around the world.’

Later, he told U.S. magazine People: ‘She’s gone. She now belongs to the ages.

German pensioners ‘kidnap and torture their investment adviser’

Suspects: Roland K. 74, seen here with his 79-year-old wife is accused of kidnapping James Amburn – dm

A group of well-to-do pensioners who lost their savings in the credit crunch staged an arthritic revenge attack and held their terrified financial adviser to ransom, prosecutors said yesterday.

The alleged kidnapping is the latest example of what is being dubbed “silver crime” — the violent backlash of pensioners who feel cheated by the world.

“As I was letting myself into my front door I was assaulted from behind and hit hard,” the financial adviser James Amburn, a 56-year-old German-American, said. “Then they bound me with masking tape until I looked like a mummy. I thought I was a dead man.”

He was freed by 40 heavily armed policemen from the counter-terrorist unit last Saturday. The frightened consultant was in his underwear, his body lacerated by wounds allegedly inflicted by angry pensioners.

It appears that two couples had entrusted Mr Amburn’s investment company with €2.4 million (£2 million), which he ploughed into Florida’s boom-and-bust property market. The properties became forfeit during the sub-prime mortgage crisis but the couples wanted their money back.

After being bundled into the boot of an Audi in the west German town of Speyer, Mr Amburn was driven southwards to Chieming, close to the Austrian border, where one of the couples Roland K, and his wife, Sieglinde, 79, had a holiday home.

The financial adviser claims he was held there in a cellar for four days almost naked, fed soup twice a day and beaten. Another couple, Gerhard F, 63, and his wife, Iris, 66, both retired doctors, allegedly helped to torture the prisoner.

“I was beaten. They threatened again and again to kill me,” Mr Amburn said. At least two of his ribs were fractured.

Mr Amburn says he tried to escape once when he was permitted to smoke in the garden. He scaled the wall and ran though the rain in his underpants calling for help.

The pensioners pursued him in their car, shouting: “Stop that man! He’s a burglar!” Two locals pinned him to the pavement and he was taken back to the cellar, where he claims he received another beating.

Space shuttle science: 1908 Tunguska explosion a comet

The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth’s atmosphere, says new Cornell University research. The conclusion is supported by an unlikely source: the exhaust plume from the NASA space shuttle launched a century later.

The research, accepted for publication (June 24, 2009) by the journal Geophysical Research Letters, published by the American Geophysical Union, connects the two events by what followed each about a day later: brilliant, night-visible clouds, or noctilucent clouds, that are made up of ice particles and only form at very high altitudes and in extremely cold temperatures.

“It’s almost like putting together a 100-year-old murder mystery,” said Michael Kelley, the James A. Friend Family Distinguished Professor of Engineering at Cornell who led the research team. “The evidence is pretty strong that the Earth was hit by a comet in 1908.” Previous speculation had ranged from comets to meteors.

The researchers contend that the massive amount of water vapor spewed into the atmosphere by the comet’s icy nucleus was caught up in swirling eddies with tremendous energy by a process called two-dimensional turbulence, which explains why the noctilucent clouds formed a day later many thousands of miles away.

Noctilucent clouds are the Earth’s highest clouds, forming naturally in the mesosphere at about 55 miles over the polar regions during the summer months when the mesosphere is around minus 180 degrees Fahrenheit (minus 117 degrees Celsius).

The space shuttle exhaust plume, the researchers say, resembled the comet’s action.

A single space shuttle flight injects 300 metric tons of water vapor into the Earth’s thermosphere, and the water particles have been found to travel to the Arctic and Antarctic regions, where they form the clouds after settling into the mesosphere.

Kelley and collaborators saw the noctilucent cloud phenomenon days after the space shuttle Endeavour (STS-118) launched on Aug. 8, 2007. Similar cloud formations had been observed following launches in 1997 and 2003.

Following the 1908 explosion, known as the Tunguska Event, the night skies shone brightly for several days across Europe, particularly Great Britain — more than 3,000 miles away.

Kelley said he became intrigued by the historical eyewitness accounts of the aftermath, and concluded that the bright skies must have been the result of noctilucent clouds. The comet would have started to break up at about the same altitude as the release of the exhaust plume from the space shuttle following launch. In both cases, water vapor was injected into the atmosphere.

The scientists have attempted to answer how this water vapor traveled so far without scattering and diffusing, as conventional physics would predict.

“There is a mean transport of this material for tens of thousands of kilometers in a very short time, and there is no model that predicts that,” Kelley said. “It’s totally new and unexpected physics.”

This “new” physics, the researchers contend, is tied up in counter-rotating eddies with extreme energy. Once the water vapor got caught up in these eddies, the water traveled very quickly — close to 300 feet per second.

Scientists have long tried to study the wind structure in these upper regions of the atmosphere, which is difficult to do by such traditional means as sounding rockets, balloon launches and satellites, explained Charlie Seyler, Cornell professor of electrical engineering and paper co-author.

“Our observations show that current understanding of the mesosphere-lower thermosphere region is quite poor,” Seyler said. The thermosphere is the layer of the atmosphere above the mesosphere.

Anti-inflammatory drugs may defeat a treatment-resistant type of cancer

Effective drugs for treating a chemotherapy-resistant form of lymphoma might already be on the market according to a study that has pieced together a chemical pathway involved in the disease.

By following the trail of several molecular flags that mark this type of cancer, a team from the University of California, San Diego, the Burnham Institute for Medical Research and the University of Copenhagen Hospital have discovered that anti-inflammatory drugs used to treat arthritis will shrink lymphoma tumors in mice.

Their report, published in the July issue of the journal EMBO Molecular Medicine, also strengthens evidence for a link between inflammation and cancer.

“If this shows promise with early clinical experiments, the treatment would be immediately available,” said Michael David, a professor of biology who leads the group at UC San Diego.

The research focused on a type of non-Hodgkin lymphoma called diffuse large B-cell lymphoma. In some patients with the disease, chemotherapy works well. In a recent study of 40 patients more than 75 percent of patients with one form of this type of lymphoma survived five years or longer.

But that study also identified a group of patients whose cancer proved difficult to treat. Their tumors failed to respond to chemotherapy, and only 16 percent of patients with this form of lymphoma survived more than five years after they were diagnosed.

Several molecular flags mark this treatment-resistant lymphoma, but the links between them were unknown until now. The new paper reports that tumor cells isolated from these patients have depressed levels of a protein called SHIP1, which was known to suppress tumors. In fact, patients with the lowest levels of SHIP1 are the least likely to survive.

The resistant type of lymphoma cells also have elevated levels of miR-155, a specific example of a type of genetic material called microRNA, the team found. They demonstrated that miR-155 suppresses SHIP1 by sticking to the template for the protein, preventing its manufacture.

This raised the possibility that these patients might respond favorably to a treatment that interrupted that pathway. “It makes sense to block that loop,” said Irene Pedersen, a research scientist in the Division of Biological Sciences at UC San Diego and lead author of the paper.

The final clue came from earlier reports that an inflammatory molecule called TNFα could boost levels of miR-155. Additional laboratory work confirmed the observation for this type of lymphoma cell.

“Our study strengthens the scientific link between inflammation and tumor progression,” David said. “The prevailing thought is that you need two mutations to get cancer. But it might take just one mutation plus inflammation.”

The anti-inflammatory drugs etanercept and infliximab, which are currently used to treat arthritis and inflammatory bowel disease, work by suppressing TNFα, suggesting a new way to curb the malignancy of this type of lymphoma.

The team tested the idea in mice that had been injected with aggressive lymphoma cells and found that nascent tumors shrank in six days.

“It’s a promising result of this whole translational path,” said Pedersen, whose initial training was in cancers of the blood. “To get somewhere we had to study the mouse models and the molecular profiles. I hope it will be beneficial to patients.”

Patients with lymphoma that has not responded to chemotherapy and who are ineligible for a bone-marrow transplant will be the first to receive the new treatment. The team in Copenhagen has begun recruiting patients for an initial clinical study.

Get Yourself Some Electric Sheep

This thing is tripping me out:  http://electricsheep.org/index.cgi?&menu=samples (old link)

Correct current web site is  http://community.sheepserver.net/

I think it is reprogramming my brain somehow. It downloads new patterns as movie files as it runs so you can watch for hours and there is always something new.  The files seem to stitch together.  Some of them seem like microscopic views of living things. This is great for people like me who are obsessively goal driven.

Has anyone heard of any security / privacy concerns with this?

Electric Sheep is a distributed computing project for animating and evolving fractal flames, which are in turn distributed to the networked computers, which display them as a screensaver on the individual node computers of the distributed network. The process is transparent to the casual user, who can simply install the software as a screensaver. Alternatively, the user may become more involved with the project, manually creating sheep (video files of animated fractal flames) for upload to the server.

According to Mitchell Whitelaw in his Metacreation: Art and Artificial Life, “On the screen they are luminous, twisting, elastic shapes, abstract tangles and loops of glowing filaments.”^[1]

The name “Electric Sheep” is taken from the title of Philip K. Dick‘s novel Do Androids Dream of Electric Sheep?. The title mirrors the nature of the project: computers (androids) who have started running the screensaver begin rendering (dreaming) the fractal movies (sheep).

The sheep motif is carried over into other aspects of the project: the 100 or so sheep stored on the server at any time is referred to as ‘the flock’; creating a new fractal by interpolating or combining the sheep’s fractal code with that of another sheep is called mating/breeding; changes to the code are called mutations, etc.

The parameters that generate these movies (sheep) can be created in a few ways: they can be created and submitted by members of the electricsheep mailing list, members of the mailing list can download the parameters of existing sheep and tweak them, or sheep can be mated together automatically by the server or manually by server admins (nicknamed shepherds).

Users may vote on sheep that they like or dislike, and this voting is used for the genetic algorithm which generates new sheep. Each movie is a fractal flame with several of its parameters changed over time. The individual frames of which these movies consist are rendered using ‘spare’ processing cycles from idle computers on the distributed network of those running the screensaver application, and finished sheep (in the form of .mpg files) are distributed to the network using BitTorrent, a Peer-to-peer filesharing application which is included as part of the Electric Sheep application.

All sheep parameters and movies are distributed under the Creative Commons Attribution license and automatically downloaded by the screen saver.

The screensaver was created and released as Free Software by Scott Draves in 1999 and continues to be developed by him and a team of about five engineers. – wiki
