    There are few things as fascinating as seeing what people in the past dreamed about the future. "France in the Year 2000" is one example. The series of paintings, made by Jean-Marc Côté and other French artists in 1899, 1900, 1901 and 1910, shows artist depictions of what life might look like in the year 2000. The first series of images were printed and enclosed in cigarette and cigar boxes around the time of the 1900 World Exhibition in Paris, according to the Public Domain Review, then later turned into postcards.

    In the early twentieth century, a farmer decided that he needed to improve the agriculture on his ranch in Nevada. He figured that a well needed to be dug to bring water and nutrients to the soil above. He lived in a barren desert and the water stored deep beneath the Earth’s crust would have provided a more sustainable crop for this harsh and dry area. He knew that a well with ample water was needed to supply bountiful crops. What he didn’t know was what was waiting for him deep below the soil. He began to dig a deep...
  • New NASA images show Pluto’s moon Charon in stunning detail

    NASA’s New Horizons spacecraft has sent incredible images of Pluto’s largest moon Charon back to Earth. The latest images reveal the moon’s complex and violent history, according to NASA. “Many New Horizons scientists expected Charon to be a monotonous, crater-battered world; instead, they’re finding a landscape covered with mountains, canyons, landslides, surface-color variations and more,” explained the space agency, in a statement. The high-resolution images, which were taken on July 14 and transmitted to Earth on Sept. 21, reveal a belt of fractures and canyons just north of the moon’s equator. Four times as long as the Grand Canyon, and...

    The mass burial in Cramond, believed to be the oldest occupied village in Scotland, was uncovered in 1975 during an excavation of a Roman Bathhouse found at the site of a car park. Forty years later, a team led by the City of Edinburgh Council has embraced modern science to examine the remains of nine individuals found in the grave with fascinating results. The evidence has disproved an early theory that the bodies were victims of the bubonic plague, instead dating the individuals back another 800 years to the 6th Century AD. Thanks to state-of-the-art computer programming, researchers were able...

    Explanation: This sharp telescopic snapshot caught late September's Harvest Moon completely immersed in Earth's dark umbral shadow, at the beginning of a total lunar eclipse. It was the final eclipse in a tetrad, a string of four consecutive total lunar eclipses. A dark apparition of the Full Moon near perigee, this total eclipse's color was a deep blood red, the lunar surface reflecting light within Earth's shadow filtered through the lower atmosphere. Seen from a lunar perspective, the reddened light comes from all the sunsets and sunrises around the edges of a silhouetted Earth. But close to the shadow's edge,...

    Building on a previous study conducted at a single Bronze Age burial site in the Outer Hebrides, Dr Booth used microscopic analysis to compare the bacterial bioerosion of skeletons from various sites across the UK with the bones of the mummified bodies from Yemen and Ireland. Archaeologists widely agree that the damp British climate is not favourable to organic materials and all prehistoric mummified bodies that may be located in the UK will have lost their preserved tissue if buried outside of a preservative environment such as a bog.

    NASA ^ | October 02, 2015 | (see photo credit)
    Explanation: A darkened and mysterious north polar region informally known as Mordor Macula caps this premier high-resolution portrait of Charon, Pluto's largest moon. Captured by New Horizons near its closest approach on July 14, the image data was transmitted to Earth on September 21. The combined blue, red, and infrared data is processed to enhance colors, following variations in surface properties with a resolution of about 2.9 kilometers (1.8 miles). In fact, Charon is 1,214 kilometers (754 miles) across, about 1/10th the size of planet Earth but a whopping 1/2 the diameter of Pluto itself. That makes it the largest...

According to a study by the Institute of Catalysis and Environment in Lyon (IRCELYON, CNRS / University Lyon 1) and the Leibniz Institute for Tropospheric Research (TROPOS), the oceans are producing unexpectedly large quantities of isoprene – a volatile organic compound (VOC) – which is known to have a cooling effect on climate. Isoprene is a gas that is formed by both the vegetation and the oceans. It is very important for the climate because this gas can form particles that...

  • Evolution's Top Example Topples

    10/01/2015 6:16:47 AM PDT · by lasereye · 74 replies
    On February 24, 1988, evolutionary biologist Richard Lenski began an ingenious ongoing experiment to test and demonstrate evolution. He and his coworkers have nursed thousands of generations of the common gut bacterium Escherichia coli, feeding them broth with limited nutrients. The team watched for decades to see if the germs might evolve a solution to this low-nutrient challenge. After about 31,500 generations, some finally cracked the code and changed. Evolution promoter Richard Dawkins wrote that this was “a beautiful example of evolution in action,” and that “creationists hate it.”1 The Harvard Gazette recently wrote, “Though the bacteria were originally genetically...

    Explanation: This stunning panorama in southern skies was recorded on the colorful night of September 27/28 from Carngegie Las Campanas Observatory. A diffuse glow and dark rifts of the central Milky Way hang over domes of the twin 6.5 meter Magellan telescopes. But most eye-catching is the deep red glow of the Moon. Immersed in Earth's shadow during the much anticipated perigee-total-lunar eclipse, the Moon's surface reflects the light of sunsets and sunrises scattered and refracted into the planet's cone-shaped umbra. Along with the dramatic hue of the eclipsed Moon, other colors of that night captured by the sensitive digital...

    Explanation: What creates these changing streaks on Mars? Called Recurring Slope Linea (RSL), these dark features start on the slopes of hills and craters but don't usually extend to the bottom. What's even more unusual is that these streaks appear to change with the season, appearing fresh and growing during warm weather and disappearing during the winter. After much study, including a recent chemical analyses, a leading hypothesis has emerged that these streaks are likely created by new occurrences of liquid salty water that evaporates as it flows. The source for the briny water is still unclear, with two possibilities...

    The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics. But the idea that we live in a 'multiverse' made up of an infinite number of parallel universes has long been considered a scientific possibility - although it is still a matter of vigorous debate among physicists. The race is now on to find a way to test the theory, including searching the sky for signs of collisions with other universes. It is important to keep in mind that the multiverse view is not actually a theory, it...

    Warming waters on the Antarctic continental shelf could be inviting to King crabs, a predator that has been unable to live in those chilly waters for tens of millions of years. Ocean waters are getting hotter, and that could make Antarctica crabby.  Warming global temperatures are prompting many animals to shift their ranges. One of those animals, the King crab, could be moving into shallower waters off the Western coast of Antarctica, where it hasn't been found for tens of millions of years.  The royal crustaceans, Lithodidae, now live on the continental slope off the western Antarctic Peninsula, a surprise...

    But based on the excavated evidence, the city’s Bronze Age heyday seems to have nevertheless come to a sudden, inexplicable end toward the end of the Middle Bronze Age—and the ancient city became a relative wasteland for 700 years, for the most part void of human habitation. The comparatively paltry or lack of Late Bronze Age material is a testament to this, with the same pattern shown in the smaller, nearby sites. A strange development, thinks Collins, for a great city-state that flourished even through the catastrophic climate changes that arguably led to the collapse of the great cities of...

They also led dignitaries including Saskatchewan Economy Minister Bill Boyd and community leaders from northern Saskatchewan on a tour of the underground workings. "We are happy to celebrate these two major uranium mining assets in Saskatchewan, the Cigar Lake mine and the...

    For decades, DARPA, the secretive research arm of the Department of Defense, has dreamed of turning soldiers into cyborgs. And now it’s finally happening. The agency has funded projects that involve implanting chips into soldiers’ brains that could one day enhance performance on the battlefield and repair traumatized brains once the fog of war has lifted. “Of the 2.5 million Americans who served in Iraq and Afghanistan, 300,000 of them came home with traumatic brain injury,” journalist Annie Jacobsen told NPR. “DARPA initiated a series of programs to help cognitive functioning, to repair some of this damage. And those programs...

    Dark streaks on Mars's surface may indicate liquid water on the barren planet, the National Aeronautics and Space Association (NASA) revealed Monday. “We now know Mars was once a planet very much like Earth with warm salty seas and fresh water lakes,” Jim Green, NASA's planetary science director, stated. “But something has happened to Mars, it lost its water.” But recent photos from NASA's Mars Reconnaissance Orbiter show long, dark streaks - some as long as 100m - which scientists believe could be a live source of flowing water - and, just maybe, could prove the existence of life (or...

    Science Daily ^ | 9/28/2015 | Jeffery Hawk, et al
    A crucial process has been identified to explain the reason why dissolved organic carbon (DOC) levels in the deep oceans are constant despite a continuous supply from the surface ocean. This research has been published today in the journal Nature Geoscience and was conducted by scientists from the National Oceanography Centre (NOC) and The University of Southampton. Dr Jeff Hawkes, the lead author of this study, from the NOC said: "There has been a long outstanding question about whether hydrothermal vents are a source or sink of organic carbon to the oceans. We have shown that hydrothermal vent fluids contain...

    Explanation: Recorded in 2014 April, this total lunar eclipse sequence looks south down icy Waterton Lake from the Waterton Lakes National Park in Alberta, Canada, planet Earth. The most distant horizon includes peaks in Glacier National Park, USA. An exposure every 10 minutes captured the Moon's position and eclipse phase, as it arced, left to right, above the rugged skyline and Waterton town lights. In fact, the sequence effectively measures the roughly 80 minute duration of the total phase of the eclipse. Around 270 BC, the Greek astronomer Aristarchus also measured the duration of lunar eclipses - though probably without...

    Tonight, as the full Moon reaches its closest point to Earth, it will also be dimmed by a total lunar eclipse. This Supermoon eclipse will reach totality at 10:11 p.m Eastern Time, and will last one hour and 12 minutes. According to NASA, it will “be visible to North and South America, Europe, Africa, and parts of West Asia and the eastern Pacific.”

    The unfortunate drama surrounding the collision and sinking of the Ady Gil has finally reached a conclusion. An arbitrator last week ruled that the Sea Shepherd acted “wrongful” in their decision to scuttle the ship and not allow for proper salvage efforts. The trimaran, named for its benefactor and owner Ady Gil, a Hollywood TV businessman and animal activist, famously collided on January 7th, 2010 with a Japanese whaling vessel. The event, captured on film for Animal Planet’s “Whale Wars” reality series, drew international attention for both the conservation organization and its anti-whaling mission. While the Ady Gil was disabled...

    Side-effects of drugs taken for insomnia and anxiety kill thousands. Why do doctors hand them out like Smarties? Updated: 04:22 EST, 15 September 2015 Soaring drug use, a growing number of addicts, far too few clinics to treat them and a rising death toll. This might sound like a scene from an impoverished country run by drug cartels - but it is, in fact, the day-to-day reality for NHS patients who are prescribed psychiatric drugs to treat anxiety, insomnia and depression. More than 80 million prescriptions for psychiatric drugs are written in the UK every year. Not only are these...

    Explanation: Tonight a bright full Moon will fade to red. Tonight's moon will be particularly bright because it is reaching its fully lit phase when it is relatively close to the Earth in its elliptical orbit. In fact, by some measures of size and brightness, tonight's full Moon is designated a supermoon, although perhaps the "super" is overstated because it will be only a few percent larger and brighter than the average full Moon. However, our Moon will fade to a dim red because it will also undergo a total lunar eclipse -- an episode when the Moon becomes completely...
