    New York Post ^ | 7/24/14 | James Billington
    Two years ago we were all going about our daily business blissfully unaware that our planet almost plunged into global catastrophe. A recent revelation by NASA explains how on July 23, 2012 Earth had a near miss with a solar flare, or Coronal Mass Ejection (CME), from the most powerful solar storm on the sun in over 150 years, but nobody decided to mention it. Err, what? Well that’s a sobering bit of news. “If it had hit, we would still be picking up the pieces,” says Daniel Baker of the University of Colorado. We managed to just avoid the...
  • Mount Rainier Could Be On The Brink Of A Monstrous Eruption

    Mount Rainier, one of the most dangerous volcanoes in the U.S. and in the world, is widely expected to erupt again. The only unknown facing scientists is when the massive stratovolcano, 4,392 meters tall and located 87 kilometers southeast of Seattle in Washington state, will finally explode. Scientists from the United States and Norway recently mapped the electric and magnetic signatures of magma flows beneath Mount Rainier (pronounced “ray-near”). They’ve also discovered a mammoth magma reservoir below the mountain that will fuel any eruption with massive magma flows. The research found out that magma or fluid molten rock is trapped...

    Explanation: This alluring all-skyscape was taken 5,100 meters above sea level, from the Chajnantor Plateau in the Chilean Andes. Viewed through the site's rarefied atmosphere at about 50% sea level pressure, the gorgeous Milky Way stretches through the scene. Its cosmic rifts of dust, stars, and nebulae are joined by Venus, a brilliant morning star immersed in a strong band of predawn Zodiacal light. Still not completely dark even at this high altitude, the night sky's greenish cast is due to airglow emission from oxygen atoms. Around the horizon the dish antenna units of the Atacama Large Millimeter/submillimeter Array, ALMA,...

    Explanation: Why does this starfield photograph resemble an impressionistic painting? The effect is created not by digital trickery but by large amounts of interstellar dust. Dust, minute globs rich in carbon and similar in size to cigarette smoke, frequently starts in the outer atmospheres of large, cool, evolved stars. The dust is dispersed as the star dies and grows as things stick to it in the interstellar medium. Dense dust clouds are opaque to visible light and can completely hide background stars. For less dense clouds, the capacity of dust to preferentially reflect blue starlight becomes important, effectively blooming the...

Rutherford RogersSo-called climate skeptics, practicing proper science by disproving the hypothesis that human CO2 is causing global warming, achieved a great deal. This, despite harassment by formal science agencies, like the Royal Society, and deliberate neglect by the mainstream media. It combined with an active and deliberate Public Relations campaign, designed to mislead and confuse.

    Once overlooked because of its relative inactivity compared to other subduction zones around the world, the Cascadia Subduction Zone (CSZ) — and the potentially devastating megathrust earthquakes and tsunamis it could unleash — are today well known to both geoscientists and the public. Beginning with the efforts of John Adams of the Geological Survey of Canada and Brian Atwater of the U.S. Geological Survey in the late 1980s, a series of oceanic research cruises and datasets has steadily advanced our understanding of Cascadia. It seems like there is “a paradigm change every few years,” says Chris Goldfinger, a geologist at...

    A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum -- the time in the sun's 11-year cycle when it is the most active. But now, there is hardly a sunspot in sight. If you look closely at the image above, taken on July 18 by NASA's Solar Dynamics Observatory, you will see a tiny smidge of brown just right of center where a small sunspot appears to be developing. But just one day before, there truly was nothing. It was a totally spotless day....

    Things are heating up on planet Earth. Average global temperatures shattered records this June ... for the second month in a row, according to a new report from the National Climactic Data Center. The NCDC, a division of the National Oceanic and Atmospheric Administration, analyzed data from 2,000 weather stations scattered across the globe measuring both ocean and land temperatures and found that global average temperatures surpassed the previous record by 1.3 degrees Fahrenheit. That makes June 2014 the warmest June since record keeping began in 1880. If this trend continues, 2014 could top 2010 as the warmest year recorded.

    Explanation: Yes, but have you ever seen aurora from a cave? To capture this fascinating juxtaposition between below and above, astrophotographer Bjargmundsson spent much of a night alone in the kilometer-long Raufarhólshellir lava cave in Iceland during late March. There, he took separate images of three parts of the cave using a strobe for illumination. He also took a deep image of the sky to capture faint aurora, and digitally combined the four images later. The 4600-year old lava tube has several skylights under which stone rubble and snow have accumulated. Oh -- the person standing on each mound --...

    UPI ^ | 07/22/2014 | Brooks Hays
    Climate change skeptics have suggested a recent slowdown in the warming of the Earth is evidence that global warming is a farce and that climate models can't be trusted, but new research suggests the slowdown, or "pause," was not a significant disruption of larger trends. The planet has been slowly warming over the last century or more. But in the last 15 years, that rate of warming has slowed. Temperatures are still high by historical standards; but between 1998 and 2013 they were slightly below what climate models had predicted. A small number of scientists and policy makers have pointed...

    Climate alarmists sometimes like to claim skeptical scientists don’t exist, but they do, and one meteorologist had a lot to say on the subject. In an interview with the MRC’s Business and Media Institute, well-known meteorologist Joe Bastardi dissected and criticized major aspects of the climate change alarmism movement. Drawing on his knowledge of weather and climate history, Bastardi said that “extreme weather” events the media talk about so much are commonplace and the result of normal variability. He also attacked basic arguments about CO2, scientific consensus and alarmist media bias. Bastardi contended that climate alarmism is “ludicrous” and “not...

Excavating here in 1965–66, as part of the UNESCO-funded campaign to salvage sites destined to be flooded by the construction of the Aswan High Dam, Dr Wendorf found a cemetery (site 117) containing at least 61 individuals dating back to about 13,000 years ago. This discovery was of great significance for two reasons. First, as a designated graveyard, evidently used over several generations, it is one of...

    About 400 footprints were first discovered in the cave in 1965. Scientists initially attributed the impressions to a man, woman and child who lived 10,000 to 15,000 years ago. But radiocarbon measurements of two cave bear bones excavated just below the footprints now indicate that Homo sapiens made these tracks around 36,500 years ago, say anthropologist David Webb of Kutztown University in Pennsylvania and his colleagues. Analyses of 51 footprints that remain — cave explorers and tourists have destroyed the rest — indicate that six or seven individuals, including at least one child, entered the cave after a flood had...

    Explanation: Why does this comet's nucleus have two components? The surprising discovery that Comet 67P/Churyumov–Gerasimenko has a double nucleus came late last week as ESA's robotic interplanetary spacecraft Rosetta continued its approach toward the ancient comet's core. Speculative ideas on how the double core was created include, currently, that Comet Churyumov–Gerasimenko is actually the result of the merger of two comets, that the comet is a loose pile of rubble pulled apart by tidal forces, that ice evaporation on the comet has been asymmetric, or that the comet has undergone some sort of explosive event. Pictured above, the comet's unusual...

    Explanation: What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere, causing visible aurorae.

    New research, supported by the National Science Foundation (NSF), counters a widely-held scientific view that thawing permafrost uniformly accelerates atmospheric warming, indicating instead that certain Arctic lakes store more greenhouse gases than they emit into the atmosphere. The study, published this week in the journal Nature, focuses on thermokarst lakes, which occur as permafrost thaws and creates surface depressions that fill with melted fresh water, converting what was previously frozen land into lakes. The research suggests that Arctic thermokarst lakes are "net climate coolers" when observed over longer, millennial, time scales. "Until now, we've only thought of thermokarst lakes as...

In the mosaic image, composed with narrowband data from the 2.5 meter Isaac Newton Telescope, it spans some 2.5 full moons toward the constellation Cepheus. Recently discovered by French astro-imager Nicolas Outters, the remarkable nebula's bipolar shape and emission are consistent with it being a planetary nebula, the gaseous shroud of a dying sun-like star, but its actual distance and origin are unknown. A new investigation suggests Ou4 really lies within the emission region SH2-129 some 2,300 light-years away. Consistent with that...

    The comet 67P/Churyumov-Gerasimenko may actually be two objects stitched together. New images from ESA's Rosetta spacecraft show an odd constriction near the middle of the comet, suggesting that two clumps of matter may have merged in what scientists call a contact binary. The conclusions are preliminary, as Rosetta was still roughly 12,000 kilometers away from the comet when the images were taken. The comet could also have had a more regular single shape with parts carved out through impacts or ice melting as the object circled the sun, mission scientists say. They will have more details about the comet's...

    According to the report, the future mission should focus on taking a closer look at the ocean that scientists suspect lies below the surface; characterizing its icy crust and looking for any subsurface liquid water; determining the surface composition and chemistry; examining surface features and identifying landing areas for future missions; and understanding the purpose of its magnetosphere — the magnetic field surrounding the celestial body. NASA officials said the instrument proposals should focus on at least one of these exploration goals. The announcement calls for instruments designed for a spacecraft that will orbit Europa or complete several flybys, since...
  • Why the Myers-Briggs test is totally meaningless

    The Myers-Briggs Type Indicator is probably the most widely used personality test in the world. An estimated 2 million people take it annually, at the behest of corporate HR departments, colleges, and even government agencies. The company that makes and markets the test makes somewhere around $20 million each year. The only problem? The test is completely meaningless.
  • Study: Single injection of protein could reverse symptoms of Type 2 diabetes

    When mice with the human equivalent of Type 2 diabetes were injected with the protein FGF1, their blood sugar levels returned to normal over two days. Just one injection of the protein both regulated these levels and even helped reverse insulin insensitivity – the underlying cause of diabetes. Published in the journal Nature, the research on FGF1 could revolutionize diabetes treatment. In addition to being effective against diabetes, the protein has several advantages over current diabetes drugs. It does not result in dangerous side effects seen with other diabetes drugs, such as heart problems, weight gain, or hypoglycemia. Additionally, FGF1...

    Two new studies suggest that being overweight may actually protect against death from cardiovascular causes. For the first study, led by Dr. Abhishek Sharma, a cardiology fellow at the State University of New York Downstate Medical Center in Brooklyn, NY, researchers conducted a meta-analysis of 36 studies that looked at the outcomes of patients with coronary artery disease (CAD) who underwent coronary revascularization procedures, including percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). they found that patients with the lowest cardiovascular mortality risk were those who were overweight - a BMI of 25-30 kg/m2. In addition, patients who...

    Explanation: What happened to half of Saturn? Nothing other than Earth's Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the Moon and Saturn have led to an unusually high number of alignments of the ringed giant behind Earth's largest satellite. Technically termed an occultation, the above image captured one such photogenic juxtaposition from Buenos Aires, Argentina that occurred early last week. Visible to the unaided eye but best viewed with binoculars, there are...
  • Japan earthquake has raised pressure below Mount Fuji, says new study

    Mount Fuji, or Fujisan as it is known in Japanese, is the highest point on the archipelago (rising to 3,776 metres) and the national emblem, immortalised in countless etchings. In June last year Unesco added it to the World Heritage list as a "sacred place and source of artistic inspiration". But it is still an active volcano, standing at the junction between the Pacific, Eurasian and Philippine tectonic plates. Though it has rarely stirred in recorded history, it is still potentially explosive. The Tohoku – or Great East Japan – earthquake on 11 March 2011 triggered a devastating tsunami, which...

    This is what may have happened around 3,200 BC on the Lake of Mondsee (Lake Constance), resulting in the exodus of a metalworking community that lived there. When the site of this particular settlement was excavated in the 19th century, 595 stone axes and studded battleaxes, 451 arrowheads along with 12 copper axes and six daggers were discovered. These items represented highly sought-after status symbols, and would never have been left behind intentionally, unless of course the settlement had been abandoned as the result of a disaster. Well preserved foods such as charred hazelnuts, grain and pieces of apples were...

    PLOSone ^ | July 02, 2014 | Cristina Olivieri et al (see below)
    Abstract -- In the last years several phylogeographic studies of both extant and extinct red deer populations have been conducted. Three distinct mitochondrial lineages (western, eastern and North-African/Sardinian) have been identified reflecting different glacial refugia and postglacial recolonisation processes. However, little is known about the genetics of the Alpine populations and no mitochondrial DNA sequences from Alpine archaeological specimens are available. Here we provide the first mitochondrial sequences of an Alpine Copper Age Cervus elaphus. DNA was extracted from hair shafts which were part of the remains of the clothes of the glacier mummy known as the Tyrolean Iceman or...

    Explanation: Why is there a blue bridge of stars across the center of this galaxy cluster? First and foremost the cluster, designated SDSS J1531+3414, contains many large yellow elliptical galaxies. The cluster's center, as pictured above by the Hubble Space Telescope, is surrounded by many unusual, thin, and curving blue filaments that are actually galaxies far in the distance whose images have become magnified and elongated by the gravitational lens effect of the massive cluster. More unusual, however, is a squiggly blue filament near the two large elliptical galaxies at the cluster center. Close inspection of the filament indicates that...

    The U.S. government says it has developed the first ever self-guided bullets that can lock onto a target more than a mile away and maneuver midflight in order to hit its mark. The .50 caliber target tracking bullets, dubbed Extreme Accuracy Tasked Ordnance (EXACTO), are designed for military snipers, who must deal with changes in wind, light and ambient heat as they fire on a target. The EXACTO technology is being developed by Teledyne Scientific and Imaging with funding from the Defense Advanced Research Projects Agency (DARPA), which researches new military technologies and is known as a key developer of...
