At least 12,000 years ago, the most popular musical events might have taken place in torch-lit caves next to walls covered in art, according to new archaeological research in France.Stone Age-era caves there bear paintings located in the most acoustically resonant places, where sound lingers or echoes.The first cathedrals, theaters and concert halls, researchers now theorize, may have been inspired by musical performances held in caves.
WITH market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics".
In recent years, stem cell researchers have become very adept at manipulating the fate of adult stem cells cultured in the lab. Now, researchers at the Salk Institute for Biological Studies achieved the same feat with adult neural stem cells still in place in the brain. They successfully coaxed mouse brain stem cells bound to join the neuronal network to differentiate into support cells instead.
Hydrogen-powered cars will not be commercially available on a large scale before 2020, a senior official from Japanese auto maker Mazda said Monday in Spain at an international oil conference."The earliest that customers will use these environmentally-friendly vehicles in a normal way will be 2020," the general manager of the firm's technical research centre, Tsutomu Matsuoka, said at the World Petroleum Congress in Madrid, one of the oil industry's biggest events.
You may not know what it is, but you burn more than your body weight of it every day. Adenosine triphosphate (ATP), a tiny molecule that packs a powerful punch, is the primary energy source for most of your cellular functions.Now researchers at the University of Illinois have identified a key step in the cellular recycling of ATP that allows your body to produce enough of it to survive. Without this cycling of ATP and its low-energy counterpart, adenosine diphosphate (ADP), into and out of the mitochondrion, where ADP is converted into ATP, life as we know it would end.
The smallest planet in the Solar System has become even smaller, studies by the Messenger spacecraft have shown.Data from a flyby of Mercury in January 2008 show the planet has contracted by more than one mile (1.5km) in diameter over its history.Scientists believe the shrinkage is due to the planet's core slowly cooling.Studies published in the journal Science show the same process also powers the planet's magnetic field, a topic long debated by scientists.
MOSCOW (AFP) - Was it a gigantic meteorite? A tremendous bolt of lightning? Perhaps the crash of a UFO the size of Tokyo?No one is certain of the answer to one of the 20th century's greatest scientific mysteries -- the "Tunguska Event" 100 years ago this week.
CAIRO, Egypt - Egypt said Monday that it retrieved a 2,500-year-old limestone relief from London after its sale was blocked by Bonhams auction house there because it had been looted from a pharaoh's tomb.
PlanetSpace may not have kept up with the ambitious spaceship-building schedule it set out three years ago, but the U.S.-Canadian venture says it's moving ahead with concepts for a new suborbital craft as well as an orbital launch system.On the suborbital front, the company is working on a quarter-scale, turbojet-powered version of its Silver Dart hypersonic glider that will be tested as an unpiloted aerial vehicle. Meanwhile, on the orbital front, PlanetSpace says it has teamed up once again with Lockheed Martin and ATK to repitch a proposal for resupplying the international space station.SpaceX and Orbital Sciences, two companies that beat out PlanetSpace in earlier NASA competitions, say they have also submitted proposals.
A complete mandible of Homo erectus was discovered at the Thomas I quarry in Casablanca by a French-Moroccan team co-led by Jean-Paul Raynal, CNRS senior researcher at the PACEA[1] laboratory (CNRS/Université Bordeaux 1/ Ministry of Culture and Communication). This mandible is the oldest human fossil uncovered from scientific excavations in Morocco. The discovery will help better define northern Africa's possible role in first populating southern Europe.
The place is the Isis-Hathor Temple of Denderah, where the priests hasten along the columned aisle to witness an important event. The principal temple is dedicated to Hathor, whereas a small adjacent one is dedicated to Isis in which a statue of the goddess is located at the end of the aisle.It is a little before 5am on 22 July, 700 BC, the summer solstice; the priests wait to watch Sirius rise and its rays penetrate the temple to fall on Isis's gem. As they arrive the sun is still below the horizon, and they gaze impatiently for the apparent heliacal rising of the Dog Star. For the priests already knew that the appearance of Sepdet lasts only for a brief moment before Ra brightens the sky.
The SOHO spacecraft discovered its 1,500th comet this week, making the observatory the most successful comet detector.The NASA/ESA Solar and Heliospheric Observatory made its historic discovery on June 25, thanks to U.S.-based amateur astronomer Rob Matson. That puts SOHO's count ahead of all other discoverers of comets throughout history combined.
Scientists have identified a gene that may raise the risk of getting the most common kind of Alzheimer's disease by about 45 percent in people who inherit a certain form of it.That form of the gene appears to hamper a brain cell's ability to take in calcium, researchers said. If drugs can be found that reverse its effect, they may be useful in fighting Alzheimer's, researchers said.Most cases of Alzheimer's appear after age 65. So far, only one gene has been firmly established as affecting the risk of this late-onset version. The gene proposed in the new study, called CALHM1, appears to have a much smaller impact on the disease risk.
PARIS (AFP) - A hundred years ago this week, a gigantic explosion ripped open the dawn sky above the swampy taiga forest of western Siberia, leaving a scientific riddle that endures to this day.A dazzling light pierced the heavens, preceding a shock wave with the power of a thousand atomic bombs which flattened 80 million trees in a swathe of more than 2,000 square kilometres (800 square miles).
The phrase "blame it on the weather" takes new meaning in light of research suggesting that regional climate may very well have been responsible for the evolution of lifestyle, culture and even religion in the Middle East.A new study published in the journal Antiquity marks the first time researchers have applied regional climate information to geographic variation in the Y chromosome (which only men possess).
RIO DE JANEIRO (Reuters) - A group that campaigns for tribal peoples' rights denied on Tuesday that it and the Brazilian government had misled the media over photographs of an uncontacted Indian tribe in the Amazon last month.Britain's Observer newspaper reported on Sunday that the tribe, rather than being "undiscovered," had been known by the Brazilian government for nearly 100 years and the photos were an attempt to publicize the risk it faced from logging.
DAMASCUS (AFP) - Syrian archaeologists have unearthed a hieroglyph close to Damascus which dates back to the pharaonic period around 1,300 years BC, the official SANA news agency reported on Saturday."The antiquities department has discovered a hieroglyph on the outskirts of Damascus, 25 kilometres (15 miles) east (of the capital), engraved into a basalt stone slab (measuring) 70 by 50 cm (28 by 20 inches)," SANA said.
A team of researchers from UQ's Institute for Social Science Research (ISSR) has proved you don't have to be psychic to predict the future.Led by Professor Bob Stimson, and funded through an ARC Linkage grant, the research group has developed a suite of models that simulate potential patterns of population and housing growth, and the location of jobs, across the South-East Queensland region.
One of the most interesting questions considered by astrophysicists deals with the start of our universe. Indeed, there is a great deal of speculation on the subject, with different theories about how the universe began, and what may have existed before the universe came into being.
A new publication answers centuries' old questions regarding the mechanism and function of humour, identifying the reason humour is common to all human societies, its fundamental role in the evolution of homo sapiens and its continuing importance in the cognitive development of infants.Alastair Clarke explains: "The theory is an evolutionary and cognitive explanation of how and why any individual finds anything funny. Effectively it explains that humour occurs when the brain recognizes a pattern that surprises it, and that recognition of this sort is rewarded with the experience of the humorous response, an element of which is broadcast as laughter.
WASHINGTON (AFP) - Martian dirt is apparently good enough for asparagus to grow in, NASA scientists said Thursday, as they announced the results of a soil analysis collected by the US Phoenix Mars lander."There is nothing about the soil that would preclude life. In fact it seems very friendly," said Samuel Kounaves, the project's lead chemist at the University of Arizona in a telephone press conference."The soil you have there is the type of soil you have in your backyard," said Kounaves. "You may be able to grow asparagus very well."
WASHINGTON (AFP) - A five-year project has revolutionized scientific thought on the evolution of birds and the results are so surprising that now even the textbooks will have to be rewritten, a study said Thursday."With this study, we learned two major things," said Sushma Reddy, lead author and a fellow at The Field Museum in Chicago, Illinois.
At a desert test site in Texas, a street battle rages between US soldiers and local "insurgents". It's much like any other training exercise, except the soldiers are accompanied by a Mule (Multifunctional utility/Logistics & Equipment), an armed robot the size of a Humvee. The insurgents are positioned overlooking an intersection, a potential kill zone. The commander pulls out what looks like a PlayStation gamepad and the Mule is sent forward.
Cuba has approved what is believed to be the world's first registered lung cancer vaccine and is offering it to Cuban and foreign patients in its hospitals.The therapeutic vaccine CimaVax EGF extends life with few side effects, and is another step in Cuba's expertise in biotechnology. It was unveiled on Monday at Havana's centre of molecular immunology.
Fewer astronauts, more robots. That's the call from three European aerospace engineers, who argue that crewed satellite repair missions - like the ones flown by NASA to fix the ailing Hubble Space Telescope - are expensive, wasteful and set the wrong agenda for the space community.The trio - Alex Ellery, Joerg Kreidsel and Bernd Sommer - argue in the journal Acta Astronautica that while such missions may be spectacular, they are unsustainable. Space agencies and satellite operators should instead be accelerating their efforts to develop robotic mechanics that can ply various Earth orbits, fixing errant satellites on demand. That way failing spacecraft can be repaired much more economically.
WILL Australia's farmers fall for the charms of drought-resistant wheat, even if it's genetically modified? Faced with climate change and a growing food crisis, enthusiasts certainly hope such traits will help overcome aversion to GM technology.Of 24 strains of GM wheat tested in field trials, two lines exceeded the yield of the non-GM variety by 20 per cent under drought conditions, according to German Spangenberg of the Victoria Department of Primary Industries in Melbourne, Australia. The results were presented last week at the Bio2008 convention in San Diego, California.
Drizzle once fell on Martian soil, according to a new geochemical analysis by Berkeley scientists, though the rain probably stopped several billion years ago.Drawing on soil data from the five missions to Mars before the current Phoenix Lander and comparing it to information collected in Earth's driest places, the scientists concluded that water must have fallen from above, not welled up from below, as has been thought.
Humans have been attempting to send messages to the stars since ... I'm going to say the early '70s. I mean, theoretically some caveman could have yelled, "Hey! Stars! You suck!" a hundred thousand years ago, but he was an idiot.But of all the messages sent into space, which ones are good? Which ones conform to quality standards? That's what I'm here to tell you.
Coiled up in a tornado is as much energy as an entire power plant. So a Canadian engineer has a plan to spin up his own twister and extract energy from its tethered tail.It all depends on heating the air near the surface so that it is much warmer than the air above."You can generate energy whenever you have a temperature gradient," said Louis Michaud. "The source of the energy here is the natural movement of warm and cold air currents."
MEXICO CITY (Reuters) - Archeologists are opening a cave sealed for more than 30 years deep beneath a Mexican pyramid to look for clues about the mysterious collapse of one of ancient civilization's largest cities.The soaring Teotihuacan stone pyramids, now a major tourist site about an hour outside Mexico City, were discovered by the ancient Aztecs around 1500 AD, not long before the arrival of Spanish explorers to Mexico.
CNN's Carol Costello reports on a study that shows how magic mushrooms affect the psyche.
Santiago: Eight perfectly preserved mummies, believed to be some 4,500 year old, were found by workers engaged in a restoration project in Chile's far north, Spain's EFE news agency reported on Saturday quoting media report."These mummies date back to between 2,000 BC and 5,000 BC." archaeologist Calogero Santoro told the daily El Mercurio.
QUEBEC - As buried treasures go, carbonized crumbs of centuries-old food likely wouldn't make it on to many people's Top 10 list.But to hear archeology doctoral student Julie-Anne Bouchard-Perron tell it, the modest materials she has helped to unearth on this forested hilltop in Cap Rouge, a wealthy suburb at the western limit of Quebec's provincial capital, are a motherlode of Canadian artifacts.
Metal rods and cables of the historic Dewey Bridge dangle over the Colorado River on April 29, east of Moab, Utah. The bridge was burned down when a child playing with matches lit dry brush nearby.So when the 92-year-old Dewey Bridge, about 30 miles northeast of town, burned this spring, Irish's neighbors offered condolences."Everybody in Moab called me. You'd think I'd lost my lovely wife," said Irish, 79, a lifelong Moab resident who led an effort to refurbish the bridge eight years ago.
Earth emits an ear-piercing series of chirps and whistles that could be heard by any aliens who might be listening, astronomers have discovered.The sound is awful, a new recording from space reveals.Scientists have known about the radiation since the 1970s. It is created high above the planet, where charged particles from the solar wind collide with Earth's magnetic field. It is related to the phenomenon that generates the colorful aurora, or Northern Lights.
BAD AROLSEN, Germany - From prison brothels to slave labor camps, 15 scholars concluded a two-week probe Thursday of an untapped repository of millions of Nazi records, and hailed it as a rich vein of raw material that will deepen the study of the Holocaust.It was the first concentrated academic sweep of the long-private archive administered by the International Tracing Service since it opened its doors last November to Holocaust survivors, victims relatives and historical researchers.
Medieval bones from six different Danish cemeteries reveal that monks who wrote Biblical texts and other religious materials may have been exposed to toxic mercury, which was used to formulate just one of their ink colors: red.The study, which will be published in the August issue of the Journal of Archaeological Science, also describes a previously undocumented disease, called FOS, which was like leprosy and caused skull lesions. Additionally, the researchers found that mercury-containing medicine had been administered to 79 percent of the interred individuals with leprosy and 35 percent with syphilis.
MEXICO CITY: Scientists were fascinated by the ghostly find: a human skeleton buried in an Aztec temple with a clay, skull-shaped whistle in each bony hand.But no one blew into the noisemakers for nearly 15 years. When someone finally did, the shrill, windy screech made the spine tingle.If death had a sound, this was it.
BELGRADE (Reuters Life!) - A fragment of a human jaw found in Serbia and believed to be up to 250,000 years old is helping anthropologists piece together the story of prehistoric human migration from Africa to Europe."This is the earliest evidence we have of humans in the area," Canada's Winnipeg University anthropology professor Mirjana Roksandic told Reuters.The fragment of a lower jaw, complete with three teeth, was discovered in a small cave in the Sicevo gorge in south Serbia.
