  • The Star-Spangled Banner: Family Keepsake

    09/21/2014 8:38:44 AM PDT · by SunkenCiv · 5 replies
    Smithsonian ^ | retrieved 2014 | unattributed
    While Francis Scott Key's song was known to most Americans by the end of the Civil War, the flag that inspired it remained an Armistead family keepsake. It was exhibited occasionally at patriotic gatherings in Baltimore but largely unknown outside of that city until the 1870s. The flag remained the private property of Lieutenant Colonel Armistead's widow, Louisa Armistead, his daughter Georgiana Armistead Appleton, and his grandson Eben Appleton for 90 years. During that time, the increasing popularity of Key's anthem and the American public's developing sense of national heritage transformed the Star-Spangled Banner from a family keepsake into a...

    Explanation: How would Saturn look if its ring plane pointed right at the Sun? Before August 2009, nobody knew. Every 15 years, as seen from Earth, Saturn's rings point toward the Earth and appear to disappear. The disappearing rings are no longer a mystery -- Saturn's rings are known to be so thin and the Earth is so near the Sun that when the rings point toward the Sun, they also point nearly edge-on at the Earth. Fortunately, in this third millennium, humanity is advanced enough to have a spacecraft that can see the rings during equinox from the side....

    Sunshine tied to suicide risk: study Fri, Sep 12 2014 By Andrew M. Seaman NEW YORK (Reuters Health) - Exposure to sunshine over a short period of time may increase the risk of suicide but may also lower the risk over several months, suggests a new study from Austria. People shouldn’t avoid the sun based on the study’s findings, says its senior author. Instead, they may consider adding sunshine to the list of factors that may influence the risk of suicide. “Suicide is complicated and has many risk factors,” said Dr. Matthaeus Willeit from the University of Vienna. “People always...

    Was This The First Robot Ever Arrested? On August 18, 1982 the Beverly Hills Police Department took a rather unusual perp into custody: a robot called DC-2. The crime? Illegally distributing business cards and generally causing a commotion on North Beverly Drive. It was probably the first time a robot had ever been arrested. When BHPD approached DC-2, the person operating it via remote control refused to identify himself to police. Officers searched the immediate area, but whoever was behind the thing was nowhere to be found. The bot's mysterious operator wasn't afraid of a little joking around though, despite...

    Explanation: Against dark rifts of interstellar dust, the ebb and flow of starlight along the Milky Way looks like waves breaking on a cosmic shore in this night skyscape. Taken with a digital camera from the dunes of Hatteras Island, North Carolina, planet Earth, the monochrome image is reminiscent of the time when sensitive black and white film was a popular choice for dimmly lit night- and astro-photography. Looking south, the bright stars of Sagittarius and Scorpius are near the center of the frame. Wandering Mars, Saturn, and Zubenelgenubi (Alpha Librae) form the compact triangle of bright celestial beacons farther...

    Explanation: For astrobiologists, these may be the four most tantalizing moons in our Solar System. Shown at the same scale, their exploration by interplanetary spacecraft has launched the idea that moons, not just planets, could have environments supporting life. The Galileo mission to Jupiter discovered Europa's global subsurface ocean of liquid water and indications of Ganymede's interior seas. At Saturn, the Cassini probe detected erupting fountains of water ice from Enceladus indicating warmer subsurface water on even that small moon, while finding surface lakes of frigid but still liquid hydrocarbons beneath the dense atmosphere of large moon Titan. Now looking...

    Explanation: In this crowded starfield covering over 2 degrees within the high flying constellation Cygnus, the eye is drawn to the Cocoon Nebula. A compact star forming region, the cosmic Cocoon punctuates a long trail of obscuring interstellar dust clouds. Cataloged as IC 5146, the nebula is nearly 15 light-years wide, located some 4,000 light years away. Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by the young, hot stars and blue, dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star near the center of this nebula...

    Explanation: It has been a good week for auroras. Earlier this month active sunspot region 2158 rotated into view and unleashed a series of flares and plasma ejections into the Solar System during its journey across the Sun's disk. In particular, a pair of Coronal Mass Ejections (CMEs) impacted the Earth's magnetosphere toward the end of last week, creating the most intense geomagnetic storm so far this year. Although power outages were feared by some, the most dramatic effects of these impacting plasma clouds were auroras seen as far south as Wisconsin, USA. In the featured image taken last Friday...

    There's some truth to the effectiveness of folk remedies and old wives' tales when it comes to serious medical issues, according to findings by a team from Detroit Medical Center. Dr. Sonal Saraiya and her colleagues in Michigan found that packing strips of cured pork in the nose of a child who suffers from uncontrollable, life-threatening nosebleeds can stop the hemorrhaging, a discovery that won them a 2014 Ig Nobel prize, the annual award for sometimes inane, yet often surprisingly practical, scientific discoveries. This year's winners honored Thursday at Harvard University by the Annals of Improbable Research magazine

    The first manned missions to Earth's satellite began in 1969 with Apollo 11. Just a few years later, conspiracies sprouted up claiming that potentially each of the six lunar landing crews and every one of the 12 Apollo astronauts who walked on the moon had in fact participated in an elaborate ruse. To the conspiracists, it may never have happened -- or didn't happen like NASA said it did -- and oh by the way, we duped the Russians into losing the space race. Voxel global illumination, however, proves them wrong, says Nvidia. The technique, which the new GTX 970...

    Geology.com ^ | 9/19/2014 | Hobart King
    Corundum is a rock-forming mineral that is found in igneous, metamorphic, and sedimentary rocks. It is an aluminum oxide with a chemical composition of Al2O3 and a hexagonal crystal structure. The mineral is widely known for its extreme hardness and for the fact that it is sometimes found as beautiful transparent crystals in many different colors. The extreme hardness makes corundum an excellent abrasive, and when that hardness is found in beautiful crystals, you have the perfect material for cutting gemstones.

    Geology.com ^ | 09/18/2014 | Hobart King
    Throughout the 20th century most people would never have thought about Canada being an important producer of diamonds. [1] Their knowledge of diamonds was fixed on mining operations in Africa and diamond trading centers in Europe. All of this started to change in 1991 when two geologists, Chuck Fipke and Stewart Blusson, found evidence of diamond-bearing Kimberlite pipes about 200 miles north of Yellowknife, Northwest Territories. One of these pipes would soon be developed by BHP Billiton into the EKATI Diamond Mine, which produced Canada's first commercial diamonds in 1998.

    An Oopart (out of place artifact) is a term applied to dozens of prehistoric objects found in various places around the world that, given their level of technology, are completely at odds with their determined age based on physical, chemical, and/or geological evidence. Ooparts often are frustrating to conventional scientists and a delight to adventurous investigators and individuals interested in alternative scientific theories. In 1991, the appearance of extremely tiny, coil-shaped artifacts found near the banks of Russia’s Kozhim, Narada, and Balbanyu rivers brought about a debate that has continued to this day. These mysterious and minuscule structures suggest that...

    Chances are chocolate milk was a staple for you growing up. Kids chug the stuff no matter what the occasion, whether it’s with breakfast, lunch, or as an after-school snack. Chocolate powder, chocolate syrup — it’s all good. That is, until you get older. Chocolate milk is for kids, right? So as an adult, it’s either regular milk (almond milk if you’re about that non-dairy life) or bust. But a scoop or drizzle of chocolate isn’t only totally OK to have as an adult, it boasts some serious benefits.

    The waters just west of San Francisco's Golden Gate Bridge hide a graveyard of sunken ships. By some estimates, there are 300 wrecks in the Gulf of the Farallones National Marine Sanctuary and the Golden Gate National Recreation Area alone. But only a fraction of them have been seen by scientists. Marine archaeologists and researchers with the National Oceanic and Atmospheric Administration (NOAA) have set out to document those lost vessels. Over the course of a five-day survey that just ended yesterday (Sept. 15), the team discovered the sites of at least four wrecks: the 1910 SS Selja shipwreck, the...

    Of all of the world's species, humans and chimpanzees are some of the only to engage in coordinated attacks on other members of their same species. Jane Goodall was among the first to introduce the occurrence of lethal inter-community killings and since then primatologists and anthropologists have long debated the concept of warfare in this genus. Research theories have pointed to increased gains and benefits of killing off competitors and opening up increased access to key resources such as food or mates. In contrast, others have argued that warfare is a result of human impact on chimpanzees, such as habitat...

    Apple said Wednesday night that it is making it impossible for the company to turn over data from most iPhones or iPads to police — even when they have a search warrant — taking a hard new line as tech companies attempt to blunt allegations that they have too readily participated in government efforts to collect user information. The move, announced with the publication of a new privacy policy tied to the release of Apple’s latest mobile operating system, iOS 8, amounts to an engineering solution to a legal quandary: Rather than comply with binding court orders, Apple has reworked...

    Puffy pedant Neil deGrasse Tyson is enduring a meteor shower of criticism over his totally unscientific obsession with how stupid everyone is. Most notably, from The Federalist, which first published, “Another Day, Another Quote Fabricated by Neil deGrasse Tyson” and followed it up with, “Did Neil deGrasse Tyson Just Try to Justify Blatant Quote Fabrication.” Turns out, Neil is a complete d*****.

    The Week ^ | 9/16/14 | Bonnie Kristian
    A new study from the American Journal of Political Science indicates that different political affiliations may actually correspond with different body odors. The researchers, led by Brown University political scientist Rose McDermott, found that conservatives and liberals smell dissimilar. While the difference is small, it is apparently significant enough that we subconsciously prefer the scent of those who vote like we do. "It appears nature stacks the deck to make politically similar partners more attractive to each other in unconscious ways," the researchers wrote.Previous research has found a number of other political view correlations with unknown degrees of biological and...

    The sea ice around Antarctica is at a record high since satellites started recording, and snowfall is thumping down on the northern Antarctic Peninsula*, but alas — some glaciers on the same peninsula are continuing to melt, just like they have done for 300 years. Hence, a team of researchers-with-models conclude that this means these glaciers are especially, very, super-sensitive to air temperature changes and will “likely” melt fast, raise sea-levels, and disappear in 200 years time.Glaciers in northern Antarctic Peninsula melting faster than ever despite increased snowfall Increased snowfall will not prevent the continued melting of glaciers in the...

    Forty-six percent of doctors give President Obama's healthcare law a "D" or an "F," according to a new survey from the Physicians Foundation. In contrast, just 25 percent of those surveyed gave the law an "A" or a "B." The findings come from a survey that was emailed to "virtually every physician in the United States with an email address on record with the American Medical Association" this March through June as the law's major provisions were taking effect, and received more than 20,000 responses from doctors. In their comments that were included (but kept anonymous) in the report, a...

    Why the Narrative Trumps the Facts What Evolution is All About Greg Conterio, echoing Robert Bidinotto, makes the point that culture war differences often pit the facts versus the narrative. The facts can win every battle but the narrative wins the war. As Bidinotto puts it, “One of the most valuable insights I discovered in recent years is how Narratives trump everything else — including what most of us would call concern for ‘practical results.’” Conterio and Bidinotto are mainly concerned with political issues, but what lies behind their insight is our beliefs about origins.

    The Daily Caller ^ | 9-17-2014 | Dick Teresi
    Pennsylvania legislators are poised to pass into law an organ-transplant-donation bill that will make it easier for murderers to avoid detection and prosecution. Two bills, almost identical, Senate Bill 850 (SB 850) and House Bill 30 (HB 30), according to its many bipartisan sponsors, will greatly increase the number of organ donors. There are currently 121,000 people on the national waitlist for organ transplants, and laws to increase the organ supply are perennially popular in many states. Those opposing such laws are commonly accused of condemning to death people on the waitlist. Law enforcement officials, however, are taking exception to...

    Sponge divers first discovered the 2,000-year-old shipwreck off the Greek island Antikythera in 1900. They recovered fragments of bronze statues, corroded marble sculptures, gold jewelry and, most famously, the Antikythera mechanism, a clocklike astronomical calculator sometimes called the world's oldest computer. Teams led by Jacques Cousteau pulled up more artifacts and even found human remains when they visited the wreck in the 1950s and 1970s. But none of those previous expeditions had access to the Exosuit, a one-of-a-kind diving outfit that weighs 530 lbs.

    The final report from a landmark federal study on hydraulic fracturing, or fracking, found no evidence that chemicals or brine water from the gas drilling process moved upward to contaminate drinking water at a site in western Pennsylvania. The Department of Energy report, released Monday, was the first time an energy company allowed independent monitoring of a drilling site during the fracking process and for 18 months afterward. After those months of monitoring, researchers found that the chemical-laced fluids used to free gas stayed about 5,000 feet below drinking water supplies. Scientists used tracer fluids, seismic monitoring, and other tests...

    In 2014, opposition occurs at 21:00 Universal Time (UT)/5:00 PM EDT on October 7th. If this date sounds familiar, it’s because Full Moon and the second total lunar eclipse of 2014 and the ongoing lunar tetrad of eclipses occurs less than 24 hours afterwards. This puts Uranus extremely close to the eclipsed Moon, and a remote slice of the high Arctic will actually see the Moon occult (pass in front of) Uranus during totality. Such a coincidence is extremely rare: the last time the Moon occulted a naked eye planet during totality occurred back during Shakespearian times in 1591, when...

The find is exciting in itself, but it also bodes well for the spacecraft’s search for orbital debris to prepare for its close encounter with the system in July 2015. Most of Pluto’s moons were discovered while New Horizons was under development, or already on its way. Mission planners are thus concerned that there could be moons out there that aren’t discovered yet — moons that could pose...

    Psychologists have shown humans are poor judges of their own abilities, from sense of humour to grammar. Those worst at it are the worst judges of all. You're pretty smart right? Clever, and funny too. Of course you are, just like me. But wouldn't it be terrible if we were mistaken? Psychologists have shown that we are more likely to be blind to our own failings than perhaps we realise. This could explain why some incompetent people are so annoying, and also inject a healthy dose of humility into our own sense of self-regard.

    Site J is an intriguing region on Comet 67P/Churyumov–Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites, according to ESA. “As we have seen from recent close-up images, the comet is a beautiful but dramatic world – it is scientifically exciting, but its shape makes it operationally challenging,” says Ulamec. “None of the candidate landing sites met all of the operational criteria at the 100% level, but Site J is clearly the best solution.” Philae’s history making landing on comet 67P is currently scheduled for around...

    Explanation: Spacecraft Rosetta continues to approach, circle, and map Comet Churyumov-Gerasimenko. Crossing the inner Solar System for ten years to reach the vicinity of the comet last month, the robotic spacecraft continues to image the unusual double-lobed comet nucleus. The reconstructed-color image featured, taken about 10 days ago, indicates how dark this comet nucleus is. On the average, the comet's surface reflects only about four percent of impinging visible light, making it as dark as coal. Comet 67P/Churyumov–Gerasimenko spans about four kilometers in length and has a surface gravity so low that an astronaut could jump off of it. In...

    I home school a young girl. In years past, we have gone to the local air show and done such things as measure the tops and bottom of wings and rotos and figure the ratio or difference between the area of the top of the wing versus the bottom and estimated which wings had more lift than others. We measure how much area the wheels occupied on the ground and consulted with the crew chief what the tire pressure was and calculated the weight of the plane. In years past we were able to see F18s form a vapor cone...

    Opinion by Dr. Tim Ball |The World Meteorological Organization (WMO) is running a campaign using television weather presenters and national broadcasters from around the world, to influence the UN’s Climate Summit 2014 scheduled for New York City on September 23. It is a counter attack designed to offset their losing the public, political, and scientific debate.They’re releasing a series of films to, as WMO Secretary General Michel Jarroud said, “paint a compelling picture of what life could be like on a warmer planet,”…“Climate change is already leading to more extreme weather such as intense heat and rain…We need to act...

    Explanation: The first hint of what will become of our Sun was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. M27 is one of the brightest planetary nebulae on the sky, and can be seen toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us...

    Researchers at Caltech and the University of Miami in Florida found that the volcano pictures, such as those that are forming the Hawaiian Islands, illustrate that it erupts when magma gushes out as narrow jets from deep inside Earth but those pictures are wrong. Don Anderson, the Eleanor and John R. McMillian Professor of Geophysics, Emeritus, at Caltech said that new seismology data are now confirming that such narrow jets don't actually exist. He further explained that, in fact, basic physics doesn't support the presence of these jets, called mantle plumes, and the new results corroborated those fundamental ideas. It...

    Explanation: Now, as you sip your cosmic latte you can view 100 Hubble Space Telescope images at the same time. The popular scenes of the cosmos as captured from low Earth orbit are all combined into this single digital presentation. To make it, Hubble's top 100 images were downloaded and resized to identical pixel dimensions. At each point the 100 pixel values were arranged from lowest to highest, and the middle or median value was chosen for the final image. The combined image results in a visual abstraction - light from across the Universe surrounded by darkness.

    Explanation: Driven by the explosion of a massive star, supernova remnant Puppis A is blasting into the surrounding interstellar medium about 7,000 light-years away. At that distance, this remarkable false-color exploration of its complex expansion is about 180 light-years wide. It is based on the most complete X-ray data set so far from the Chandra and XMM/Newton observations, and infrared data from the Spitzer Space Telescope. In blue hues, the filamentary X-ray glow is from gas heated by the supernova's shock wave, while the infrared emission shown in red and green is from warm dust. The bright pastel tones trace...
