    NASA ^ | March 04, 2015 | (see photo credit)
    Explanation: What dark structures arise from the Pelican Nebula? Visible as a bird-shaped nebula toward the constellation of a bird (Cygnus, the Swan), the Pelican Nebula is a place dotted with newly formed stars but fouled with dark dust. These smoke-sized dust grains formed in the cool atmospheres of young stars and were dispersed by stellar winds and explosions. Impressive Herbig-Haro jets are seen emitted by a star on the right that is helping to destroy the light year-long dust pillar that contains it. The featured image was scientifically-colored to emphasize light emitted by small amounts of ionized nitrogen, oxygen,...
  • Determining recipes for some of the world's oldest preserved beers

    Phys.Org ^ | 03-04-2015 | Provided by American Chemical Society
    Some breweries have taken to resurrecting the flavors of ages past. Adventurous beer makers are extrapolating recipes from clues that archeologists have uncovered from old and even ancient brews found at historical sites. Now scientists have analyzed some of the oldest preserved beer samples from an 1840s' shipwreck to try to provide insight into how they were made. They report their findings in ACS' Journal of Agricultural & Food Chemistry. Brian Gibson and colleagues explain that in 2010, divers discovered an old schooner at the bottom of the Baltic Sea near Finland. Archeological evidence suggested the ship went down about...

    Scientists have discovered a new species of titi monkey in Brazil, according to a recent paper published in scientific journal Papéis Avulsos de Zoologia. Titis are new world monkeys found across South America. These tree-dwelling primates have long, soft fur and live in small family groups consisting of a monogamous pair and their offspring. Rather touchingly, they are often observed sitting or sleeping with their tails entwined. In 2011, researcher Julio César Dalponte spotted an unusual looking titi monkey on the east bank of the Roosevelt River, whose colouration did not match any known species. Intrigued, a team of...

    Archaeology ^ | Tuesday, March 03, 2015 | editors
    A tomb dating to the 18th Dynasty has been discovered by a team from the American Research Center in the Gorna necropolis on Luxor’s west bank. The t-shaped tomb has two large halls and an unfinished small niche at one end. A side room has a shaft that “could lead to the burial chamber,” Minister of Antiquities Mamdouh el-Damaty told Ahram Online. The walls of the tomb, which was looted and damaged in antiquity, are decorated with paintings of hunting scenes and images of the tomb’s owner, a guard of Amun’s gate, and his wife in front of an offering...

Libnah was also the site of a revolt during the reign of King Jehoram of Judah (mentioned in 2 Chronicles 21:10) when the king had forsaken "the God of his fathers".

    Newly discovered hormone mimics the effects of exercise Enlarge Credit: Martha Sexton/public domain Scientists at the USC Leonard Davis School of Gerontology have discovered a new hormone that fights the weight gain caused by a high-fat Western diet and normalizes the metabolism - effects commonly associated with exercising. Hormones are molecules that act as the body's signals, triggering various physiological responses. The newly discovered hormone, dubbed "MOTS-c," primarily targets muscle tissue, where it restores insulin sensitivity, counteracting diet-induced and age-dependent insulin resistance."This represents a major advance in the identification of new treatments for age-related diseases such as diabetes," said Pinchas...

    The jungle-choked remains of a "lost city", abandoned by a mysterious civilisation several centuries ago and long fabled for reports of its gold and "monkey children", have been uncovered in the depths of the rainforests of Honduras. A team of American and Honduran archaeologists, aided by the bushcraft and survival skills of former British SAS soldiers, has just emerged from one of the most remote locations on Earth with news of their stunning discovery. The expedition was seeking the site of the legendary "White City", also known as the "City of the Monkey God", a goal for Western explorers since...

    As the first day with Chrysler in bankruptcy dawns, let’s look at a mad car from an era when the automaker was set to conquer the very skies: the jet-powered Gilda coupé. There is something definitely wrong with the heat exchangers of Italian air conditioners. Granted, they have fans in them and machines with fans will never be silent but cooling a small building by Lake Como should not require a jet engine. There, I said it—and as if on cue, this orange-silver concoction from half a century ago rounds a bend and motorvates leisurely down a service road. The...

    On a Mediterranean beach 10 miles south of Tel Aviv, Israel, a vast new industrial facility hums around the clock. It is the world’s largest modern seawater desalination plant, providing 20 percent of the water consumed by the country’s households. Built for the Israeli government by Israel Desalination Enterprises, or IDE Technologies, at a cost of around $500 million, it uses a conventional desalination technology called reverse osmosis (RO). Thanks to a series of engineering and materials advances, however, it produces clean water from the sea cheaply and at a scale never before achieved ...

    The beautiful thing about science (when it’s conducted properly) is that multiple experts and laboratories in any field can match their findings against each other, peer review their work and subject competing theories to rigorous testing. That is, of course, providing you’re not doing work in climate research. In that case, if you come up with any figures which fly in the face of established Eco-Church doctrine, it’s time to stack up some kindling and burn the witch. A week ago, the Boston Globe, New York Times, and Washington Post ran stories repeating claims made by long-time Greenpeace staffer...

    NASA ^ | March 03, 2015 | (see photo credit)
    Explanation: It was late in the northern martian spring when the HiRISE camera onboard the Mars Reconnaissance Orbiter spied this local denizen. Tracking across the flat, dust-covered Amazonis Planitia in 2012, the core of this whirling dust devil is about 140 meters in diameter. Lofting dust into the thin martian atmosphere, its plume reaches about 20 kilometers above the surface. Common to this region of Mars, dust devils occur as the surface is heated by the Sun, generating warm, rising air currents that begin to rotate. Tangential wind speeds of up to 110 kilometers per hour are reported for dust...
  • The first ever photograph of light as both a particle and wave

    03/02/2015 12:52:37 PM PST · by C19fan · 28 replies
    Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior. Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different...

    Hydria Project ^ | 2009 | MIO
    About forty kilometres south of Cairo, close to the town of Helwan, lie the ruins of the Sadd-el-Kafara ( = "dam of the Pagans"), an embankment dam of great size built around 2700-2600 BC, discovered over 100 years ago in the old, deep and dry Garawi ravine. The masonry-faced earthen dam originally measured 14 m height and 113 m length along the crest and is considered today the oldest dam of such size known in the world. The primal aim of the dam was to retain the water from rare but violent floods. It could also ensure water to workers...

    NASA ^ | March 02, 2015 | (see photo credit)
    Explanation: It is not every day that such an interesting cloud photobombs your image. The original plan was to photograph a rare angular conjunction of Mars and Venus that occurred a week and a half ago, with the added bonus of a crescent Moon and the International Space Station (ISS) both passing nearby. Unfortunately, on Madeira Island, Portugal, this event was clouded out. During the next day, however, a spectacular lenticular cloud appeared before sunset, so the industrious astrophotographer quickly formulated a new plan. A close look at the resulting image reveals the Moon visible toward the left of the...

    ULUTH, Minn. – Research by a University of Minnesota Duluth professor that separates Earth’s natural climate variability from outside factors points in particular to greenhouse gas-induced climate change as the likely cause of the warming planet. The study found that natural climate variability probably has helped keep things cooler in recent years than they otherwise would have been due to the outside factors. The research, published Sunday in Science Magazine, was headed by the University of Minnesota Duluth’s Byron Steinman, an assistant professor of geological sciences with the Large Lakes Observatory and the Department of Earth and Environmental Sciences.

    “Magnetic reconnection is one of the most important drivers of space weather events,” said Jeff Newmark, interim director of the Heliophysics Division at NASA Headquarters in Washington. “Eruptive solar flares, coronal mass ejections, and geomagnetic storms all involve the release, through reconnection, of energy stored in magnetic fields. Space weather events can affect modern technological systems such as communications networks, GPS navigation, and electrical power grids.” The four MMS have been stacked on top of one another like pancakes, encapsulated in the payload fairing, transported to the launch pad, hoisted and mated to the top of the 195-foot-tall rocket.

The 15 warmest years, with one single exception, have come during the first 15 years of the new millennium.

    When the study participants were examined according to age, the researchers found that sleeping for more than eight hours a night increased stroke risk only for people who were at least 63 years old. On the flip side, they found that sleeping for less than six hours a night heightened stroke risk for younger people more than for older people. Finally, they discovered that “short” sleepers were more at risk for an ischemic stroke (the kind caused by a clot that blocks blood flow to the brain) while “long” sleepers were more at risk for a hemorrhagic stroke (the kind...

    [It would really be great if private entrepreneurs could develop this system! Musk is an innovator. Check out the videos in the article.] “Hyperloop moves closer to becoming reality.” Phil LeBeau@Lebeaucarnews (Hyperloop Transportation Technologies,Inc., says Elon Musk’s vision for the new transportation system is beginning to take hold. CNBC’s Phil LeBeau reports, and talks to Ahlborn about the 5-mile stretch to be tested in the next few years.) The Hyperloop, just an idea in the mind of Elon Musk two years ago, is moving closer to becoming reality. Hyperloop Transportation Technologies has signed an agreement with a developer in central...

    We all know and love the moon. We're so assured that we only have one that we don't even give it a specific name. It is the brightest object in the night sky, and amateur astronomers take great delight in mapping its craters and seas. To date, it is the only other heavenly body with human footprints. What you might not know is that the moon is not the Earth's only natural satellite. As recently as 1997, we discovered that another body, 3753 Cruithne, is what's called a quasi-orbital satellite of Earth. This simply means that Cruithne doesn't loop around...

    Explanation: Venus, named for the Roman goddess of love, and Mars, the war god's namesake, came together by moonlight in this lovely skyview, recorded on February 20 from Charleston, South Carolina, USA, planet Earth. Made in twilight with a digital camera, the three second time exposure also records earthshine illuminating the otherwise dark surface of the young crescent Moon. Of course, the Moon has moved on from this much anticipated triple conjunction. Venus still shines in the west though as the evening star, third brightest object in Earth's sky, after the Sun and the Moon itself. Seen here within almost...

    Astronomers have discovered the largest and most luminous black hole ever seen — an ancient monster with a mass about 12 billion times that of the sun — that dates back to when the universe was less than 1 billion years old. It remains a mystery how black holes could have grown so huge in such a relatively brief time after the dawn of the universe, researchers say.

    Like Earth, the interior of Mars has undergone a process known as differentiation. This is where a planet, due to its physical or chemical compositions, forms into layers, with denser materials concentrated at the center and less dense materials closer to the surface. In Mars’ case, this translates to a core that is between 1700 and 1850 km (1050 – 1150 mi) in radius and composed primarily of iron, nickel and sulfur. This core is surrounded by a silicate mantle that clearly experienced tectonic and volcanic activity in the past, but which now appears to be dormant. Besides silicon and...

    ***SNIP***The researchers used a number of techniques that are used when modeling real diseases, and the abstract ends with this dismal line: "We build up to a full scale simulation of an outbreak in the United States, and discover that for 'realistic' parameters, we are largely doomed." But Phys.Org relays a glimmer of hope by way of Alex Alemi, a grad student involved in the research: He says those who want to remain safe from the undead for as long as they can should head to the northern Rockies. He explains that while books and movies typically show an outbreak...
  • Exposed: what fracking really does to you, your family, pets and food

    The first researchers to systematically document ill health in livestock, pets, and people living near fracking drill sites were Michelle Bamberger and Robert Oswald. Bamberger, a veterinarian, and Oswald, a professor of molecular medicine at Cornell University, used a case study approach-looking at individual households-to search for possible effects (Bamberger and Oswald 2012). Many fracking chemicals are known carcinogens, endocrine disruptors or other classes of toxins (Colborn et al. 2011). Bamberger and Oswald's studies, carried out during the ongoing fracking boom, uncovered serious adverse effects including respiratory, reproductive, and growth-related problems in animals and a spectrum of symptoms in humans...

  • Astroquizzical: What happens when Betelgeuse explodes?

    Starts with a Bang! ^ | February 24, 2015 | Jillian Scudder
    Question: If Betelgeuse explodes right now, could we see it with naked eye? It is over 400 light years away, so you might think that people would see it long after it actually happens? Betelgeuse is already one of the brightest stars in the night sky, sitting somewhere around the 8th or 9th brightest star in the night sky. (These lists don’t include the Sun, which is somewhat obviously always the brightest object in the sky.) It sits in the constellation Orion, along with a number of other bright stars, and makes up the left hand shoulder of the warrior....
