Ernest Shackleton's famous ship, the Endurance, which he had to abandon in 1915 on his ill-fated Antarctic expedition, is probably still in very good condition on the ocean floor. This is one conclusion from research that studied how sunken wood degrades in southern polar waters.Experiments that submerged planks for over a year found they returned to the surface in near-pristine condition. Scientists point to the absence in the region of wood-boring "ship worms". Anywhere else in the world, these molluscs would normally devour sunken wood rapidly.But Adrian Glover from London's Natural History Museum says the currents that circle the Antarctic likely prevent the organisms from getting anywhere near the continent.
According to a University of Oxford press release dated August 13, a research team led by scientists from the prestigious British university discovered that, after examining fossils from the Cretaceous Period (145-66 million years ago), a fundamental shortening of the bony tails of the earliest birds caused the development of versatile legs and gave these animals an evolutionary edge. The findings are reported this week in the Proceedings of the Royal Society B, under the title,
Scientists in Istanbul are pleased with the success of their latest scientific achievement: glowing green rabbits.Two rabbits born from a litter of eight at the University of Istanbul proved again that genetic manipulation is possible prior to birth. The unique coloration was achieved by injecting the DNA of jellyfish into a female rabbit
According to an August 12 news release from the University of Michigan Health System, a recent animal study conducted by university researchers shows that after clinical death has been declared, there is a high level of electrical activity in the brain. The presence of this activity in the brain may provide a scientific explanation for near-death experiences reported worldwide by cardiac arrest survivors. As to whether and how the dying brain is capable of creating conscious activity has been a hot-button issue among the scientific community, the UM researchers embarked on a study of the phenomenon using rats.
Light speeds through space, bouncing off objects as it races at about 186,282 miles per second. Now, scientists may have found a way to halt this mad dash. They've discovered that they can slow light by using embedded dye molecules in a liquid crystal matrix; the findings could one day lead to new technologies in remote sensing and measurement science.Scientists have long known that a wave packet of light becomes more sluggish when it travels through matter. Yet the magnitude of this slow-down in typical materials such as glass or water is less than a factor of two. That's why researchers decided to see if there was another way to slow down light a bit further.
There is much more to Mars than meets the eye. By using the radar on Mars Express, we can see several kilometres below the surface to see what lies beneath. The radar creates subsurface images of Mars by beaming low-frequency radio waves towards the planet, which are reflected from any surface they encounter.While most are reflected by the planet's surface, some travel deeper and bounce off interfaces between layers of different material, such as between rock, water or ice.The strength and timing of the radar echoes that arrive back at Mars Express are a gauge of the depths of different types of underground interfaces.
How was our universe created 14 billion years ago? That's a good question. Scientists believe that the same conditions prevailed everywhere shortly after the Big Bang in an originally symmetrical universe. Yet this raises the question: how could a breaking of symmetry occur to form stars and galaxies? That's what researchers set to find out. Using laser-cooled ions, researchers discovered how symmetry breaking can be generated in a controlled manner and how the occurrence of defects can then be observed.Using so-called ion Culomb crystals, the researchers demonstrated topological defects in an atomic-optical experiment.
In quite an eerie feat, physicists have floated microscopic diamonds in midair using laser beams.Researchers have already used lasers to levitate extremely small particles, such as individual atoms, but this is the first time that the technique has worked on a nanodiamond, which, in this case, measures just 100 nanometers (3.9 x 10-8 inches) across, or more than 1,000 times thinner than a fingernail.In the new study, the physicists from the University of Rochester relied on the fact that a laser beam, which is made up of photons, creates a tiny force that usually can't be felt.

Astronomers have found that some asteroids in the main belt region are not dead rocks after all, but are dormant comets that may yet come back to life if the energy that they receive from the Sun increases by a few percent.A team of astronomers from the University of Antioquia, Medellin, Colombia, has discovered a graveyard of comets. The researchers, led by Ignacio Ferrin describe how some of these objects, inactive for millions of years, have returned to life, leading them to name the group the

Grown by the Aztecs and then all but eliminated in the Spanish conquest, the ancient crop amaranth may become the next quinoa. Advocates hope amaranth can help Mexicans eat healthier, better connect to their roots, and lessen their impact on the environment. But will people eat it?Amaranth is a broad-leafed, bushy plant that grows about six feet (1.8 meters) tall. It produces a brightly colored flower that can contain up to 60,000 seeds. The seeds are nutritious and can be made into a flour. Not a true grain, amaranth is often called a pseudocereal, like its relative quinoa.
LOS ANGELES (AP) -- If aliens ever target Earth, Jon Gibson and Amanda White are counting on them having an appreciation for pop art and a sense of humor.The duo created an elaborate, Andy Warhol-like design that has been etched into a satellite's panel, transforming the spacecraft into a replica of an oversized electrical charging device.If someone is going to invade our planet, presumably they're going to come in some sort of electronic, electricity-powered ship," Gibson notes whimsically. "Maybe this will make them stop for a moment and say, `These guys are nice. We're not going to destroy their planet.'"Related Video: "Art in Space" - The Universe's First Celestial Charging Station
Six scientists emerged from a space habitat on Hawaii's Big Island Tuesday (Aug. 13), ending a four-month simulated mission designed to study how best to feed astronauts during the long trip to Mars.The mission, known as Hawaii Space Exploration Analog & Simulation (or HI-SEAS for short), began in mid-April and wrapped up Tuesday morning, when the six explorers stepped onto a lava field about 8,000 feet (2,440 meters) above sea level on the northern slope of Mauna Loa."We have landed. #hiseas Mission 1 is officially over,"
On the west side of Nevada's dried-up Winnemucca Lake, there are several limestone boulders with deep, ancient carvings; some resemble trees and leaves, whereas others are more abstract designs that look like ovals or diamonds in a chain.The true age of this rock art had not been known, but a new analysis suggests these petroglyphs are the oldest North America, dating back to between 10,500 and 14,800 years ago.Though Winnemucca Lake is now barren, at other times in the past it was so full of water the lake would have submerged the rocks where the petroglyphs were found and spilled its excess contents over Emerson Pass to the north.

A fast moving, silent, circular, brightly lit object was videotaped moving across the night sky of Haskovo, Bulgaria, on August 4.The video, posted by one "nedialko kostadinov," shows the unusual object passing behind numerous wires and structures and changing colors and intensity. Near the beginning of the video is what appears to be an aircraft of some kind, possibly behind the UFO. And several commenters chime in on the YouTube page, claiming to have also seen the same object within 24 hours of the posting of this video.
A strange, newly discovered particle could shrink a laptop computer's hard drive to the size of a peanut and an iPod's drive to the size of a rice grain.The particle, called a skyrmion, is more stable and less power-hungry than its conventional, magnetic cousin. Besides storing data in ultra compact media, skyrmions could lead to faster computers that combine storage with processing power and usher in smaller and smaller devices that have the same computing power as a desktop machine.
One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. This value is so small, it is perhaps 120 orders of magnitude less than would be expected based on fundamental physics. Resolving this problem, often called the cosmological constant problem, has so far eluded theorists.

Once all roads led to Rome, the law of the known world was meted out as Lex Romanum, and the peace of the world was maintained by Roman Legions parading Pax Romanum. But, it's also true that the Romans were the first genuine masters of water. I'm holding in my hands a musty old book translated and published scarcely 40 years ago, written in Latin, close to 2,000 years ago. It's basically an autobiography of Rome's most famous water commissioner, Sextus Julius Frontinus. It's impossible to pursue water literacy without continually running into Roman sounding names like, Bernoulli, Venturi, and Vetruvius.

Boston, Mass., -- A mother's perceived social status predicts her child's brain development and stress indicators, finds a study at Boston Children's Hospital.

The most mysterious smile in art history has spawned endless speculation. Who was the model? Why is she smiling? What does the background mean? Whole books have been devoted to musing about hidden messages in the painting, including asking whether the model was actually a man, or had bad teeth, or maybe was Leonardo da Vinci himself.While speculation continues, most art historians have now coalesced around the idea that the model was a young woman named Lisa del Giocondo, née Lisa Gherardini.

A year after first teasing the public about his "Hyperloop" travel concept, billionaire entrepreneur Elon Musk has finally revealed details about the potentially revolutionary transportation system of tomorrow.Musk unveiled his vision for the Hyperloop transportation system online today (Aug. 12), saying that it could rocket passenger-packed pods through long tubes at 760 mph or so (1,220 km/h) using energy derived from the sun.
When the Perseid meteor shower bursts across the sky later this month, will people be able to hear it?For centuries, people have reported hearing a sound made by meteors as they streaked across the skies overhead. And with the Perseids about to dazzle skywatchers with a meteor display that will earn it the title "fireball champion," some researchers are wondering if the Perseid meteor shower will be heard as well as seen.
Once all roads led to Rome, the law of the known world was meted out as Lex Romanum, and the peace of the world was maintained by Roman Legions parading Pax Romanum. But, it's also true that the Romans were the first genuine masters of water. I'm holding in my hands a musty old book translated and published scarcely 40 years ago, written in Latin, close to 2,000 years ago. It's basically an autobiography of Rome's most famous water commissioner, Sextus Julius Frontinus. It's impossible to pursue water literacy without continually running into Roman sounding names like, Bernoulli, Venturi, and Vetruvius.
Scientists at Mainz University for the first time prove techniques used to produce ancient glazed beads / Investigations conducted using neutron activation analysis with the aid of the TRIGA research reactor of Mainz UniversityThe raw materials for ancient glass beads found in former Rhaetian settlements in Bavaria clearly did not originate from this region. This is the conclusion following an analysis of the beads at the TRIGA research reactor of the Institute of Nuclear Chemistry at Johannes Gutenberg University Mainz (JGU).
Boston, Mass., -- A mother's perceived social status predicts her child's brain development and stress indicators, finds a study at Boston Children's Hospital. While previous studies going back to the 1950s have linked objective socioeconomic factors -- such as parental income or education -- to child health, achievement and brain function, the new study is the first to link brain function to maternal self-perception.
The most mysterious smile in art history has spawned endless speculation. Who was the model? Why is she smiling? What does the background mean? Whole books have been devoted to musing about hidden messages in the painting, including asking whether the model was actually a man, or had bad teeth, or maybe was Leonardo da Vinci himself.While speculation continues, most art historians have now coalesced around the idea that the model was a young woman named Lisa del Giocondo, née Lisa Gherardini. "Mona" is a contraction from "madonna," which in Italian means "my lady.".
I have protested, walked picket lines, and was arrested. These confrontation tactics seem no longer effective and may in fact, hinder progress for change.My culture teaches that as an Ojibwe I have an inherent obligation to not only protect myself, my family, and my tribe but ultimately all humanity, including the environment that sustains us. We are spirit beings who came into this world to live the human experience. That spirit is love and it resides in our hearts.
"I think that this time I've actually witnessed a guardian angel at work," Jeremiah See of the New London Fire Department told ABC News.An unidentified allegedly drunken driver hit Katie Lentz, of Quincy, Mo., head on Aug. 4 while traveling on Route 19 near Center, Mo., pinning the 19-year-old in the front seat of her convertible. With her vital signs failing fast, she asked rescue crews to pray with her.That's when first responders say a man who looked like a Catholic priest seemed to appear out of nowhere, despite a 2-mile perimeter blocking the scene.Related: Simon Kruger, Rescued Boy, Claims Kangaroo Kept Him Warm While Lost In Australian Outback
Large animals help move nutrients around the landscape in much the same way as arteries carry blood around our bodies, scientists have found.And when those large creatures become extinct, these crucial "circulatory systems" are damaged, causing long-term harm to the health of soils.
When Josh Humbert inspects his farm, he dives into the clear blue waters of a lagoon, on a picture-perfect island that is fringed with palm trees. Humbert is the manager and owner of Kamoka Pearl, a boutique family business on the French Polynesian atoll of Ahe that is trying to shake up the international pearl market by raising pearls more sustainably.
The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased heat flow from the mantle and a complex interplay between this geothermal heating and the Greenland ice sheet. The international research initiative IceGeoHeat led by the GFZ German Research Centre for Geosciences establishes in the current online issue of Nature Geoscience that this effect cannot be neglected when modeling the ice sheet as part of a climate study.
