  • Man-made adjustments transform cooling to warming in Paraguay, South America

    It’s not fossil fuels causing global warming, it’s man-made adjustments. Stop the adjustments! In South America, there are hardly any rural land thermometers. GISS tells us the area is warming (see the map below). Paul Homewood looked at the raw data. There are only three rural stations currently operating in the area, Puerto Casado, Mariscal, and San Juan, and they all show a raw trend that falls. As in so many other situations, after adjustments, all three show a rising trend. The changes are breathtaking. In Mariscal raw temperatures of 25.5C turned out to be “really” 22.5C. (Those 1950...

    The Italian government on Wednesday said police had seized more than 5,000 ancient artefacts in a record 45-million-euro haul after dismantling a Swiss-Italian trafficking ring. Culture Minister Dario Franceschini said it was the country's "largest discovery yet" of looted works and consisted of 5,361 pieces, including vases, jewellery, frescoes and bronze statues, all dating from the 8th century BC to the 3rd century AD. The archaeological treasures came from illegal digs across Italy and "will be returned to where they were found", the minister told reporters. Police said the items were worth around 45 million euros ($52 million) and were...

    It is astonishing that scholars of religion refer so little to the Manichaean faith, which in its day -- roughly from the third century AD through the fourteenth century -- was a fully fledged world religion, which interacted with Christianity, Buddhism, Islam, Zoroastrianism and Judaism. At various times, its adherents could be found across the whole of Eurasia, from France to China. It also created a substantial body of scriptures and commentaries, most of which are now lost. Manichaeanism (Manichaeism) is, I believe, the only example of a world religion that has arisen and then vanished entirely, seemingly without trace....

    Science Recorder ^ | January 25, 2015 | Delila James
    One of the main challenges NASA engineers face is the very low density of the Martian atmosphere. To be able to lift off in such a thin atmosphere, the blades of the Mars Helicopter have to spin much faster than here on Earth, a report by Discovery News explains. Even operating only a few minutes a day, NASA says the solar-powered helicopter could enormously accelerate the pace of scientific discovery on the planet. Some envision swarms of these inexpensively built, automated drones zipping daily over the Martian landscape, collecting geological and atmospheric data over a large area. Given the fast...

How about Secularists for Sharia Law?” Atheists may not have a pope, but in the eyes of many there is still a proper dogma that all good atheists must adhere to. To be an atheist is to support abortion.

    A new smartphone market report reveals Apple is dominating as iPhones represented nearly half of the new device activations in the fourth quarter of 2014. "Apple had virtually double the sales of Samsung, and five times that of LG. No other brand accounted for as much as 5 percent of U.S. sales," says Lowitz. "The Amazon Fire and Blackberry smartphones registered slight share, which we attribute to random sample fluctuation as much as actual sales." The report found iPhone activations nearly doubled from the previously quarter. Apple smartphones accounted for about 28 percent of new activations in third quarter of...

    The mission to Pluto is being billed as the last great encounter in planetary exploration. It is one of the first opportunities to study a dwarf planet up close. The pictures are critical to enable the New Horizons probe to position itself for a closer fly-by later this year. As the probe is still 200 million km away, Pluto will be hardly discernable in the images - just a speck of light against the stars. But the mission team says this view is needed to help line up the spacecraft correctly for its fly-by on 14 July. "Optical navigation is...

    Explanation: Ten Earths could easily fit in the "claw" of this seemingly solar monster. The monster, actually a huge eruptive prominence, is seen moving out from our Sun in this condensed half-hour time-lapse sequence. This large prominence, though, is significant not only for its size, but its shape. The twisted figure eight shape indicates that a complex magnetic field threads through the emerging solar particles. Differential rotation of gas just inside the surface of the Sun might help account for the surface explosion. The five frame sequence was taken in early 2000 by the Sun-orbiting SOHO satellite. Although large prominences...

    Traces of painted red numbers have been discovered during the ongoing restoration of the Colosseum, indicating various sectors of the amphitheatre similar to the seating system employed by today's stadiums. The numbers were painted on the arches of the Colosseum to guide visitors to their respective stands, according to their social class. Describing it as an "exceptional discovery", the monument's director Rossella Rea said that restorers had not expected the painted numbers to have survived. The director of the restoration project Cinzia Conti said the discovery proved the delicacy of the water-powered process, which removes dirt and smog residue but...

    Consumer doggie DNA testing is old hat at this point, having been around since 2007. But cat-lovers who wish to decipher their pet's breed are out of luck -- no such tests exist for felines. That fact reflects the state of the underlying science.

By comparison, just a handful of such genes have been identified in cats. But a group of geneticists is working to close this gap by sequencing 99 domestic cats. This week the researchers...

    The crack, or fissure, could spell the beginning of the end for comet 67P/Churyumov–Gerasimenko. It is located in the neck area, in the region named Hapi, between the two lobes that make 67P appear so much like a Rubber Duck from a distance. The fissure could represent a focal point of many properties and forces at work, such as the rotation rate and axis – basically head over heels of the comet. The fissure lies in the most active area at present, and possibly the most active area overall. Though the Hapi region appears to receive nearly constant sunlight, at...

Comet C/2014 Q2 (Lovejoy), which is currently at naked-eye brightness and near its brightest, has been showing an exquisitely detailed ion tail. As the name implies, the ion tail is made of ionized gas -- gas energized by ultraviolet light from the Sun and pushed outward by the solar wind. The solar wind is quite structured and sculpted by the Sun's complex and ever changing magnetic field. The effect of the variable solar wind combined with different gas jets venting from the comet's nucleus accounts for the tail's complex structure. Following...

The outermost planet orbits in the "Goldilocks" zone, a region where surface temperatures could be moderate enough for liquid water and perhaps life, to exist. The star, EPIC 201367065, is a cool red M-dwarf about half the size and mass of our own sun. At a distance of 150 light years, the star ranks among the top 10 nearest stars known to have transiting planets. The star's proximity means it's bright enough for astronomers...

    A gigantic but fleeting burst of radio waves has been caught in the act for the first time, helping to narrow down the vast array of things that might cause them. Figuring out what these fast radio bursts are or where they come from could help answer some of the biggest cosmological questions. They last about a millisecond but give off as much energy as the sun does in a day, all seemingly in a tight band of radio-frequency waves. Their source is a mystery, but whatever causes them must be huge, cataclysmic and up to 5.5 billion light years...

    Paris (AFP) - The Solar System has at least two more planets waiting to be discovered beyond the orbit of Pluto, Spanish and British astronomers say. The official list of planets in our star system runs to eight, with gas giant Neptune the outermost. Beyond Neptune, Pluto was relegated to the status of "dwarf planet" by the International Astronomical Union in 2006, although it is still championed by some as the most distant planet from the Sun. In a study published in the latest issue of the British journal Monthly Notices of the Royal Astronomical Society, researchers propose that "at...

    Explanation: It is the largest asteroid in the asteroid belt -- what secrets does it hold? To find out, NASA has sent the robotic Dawn spacecraft to explore and map this cryptic 1,000-kilometer wide world: Ceres. Orbiting between Mars and Jupiter, Ceres is officially categorized as a dwarf planet but has never been imaged in detail. Featured here is a 20-frame video taken a week ago of Dawn's approach that now rivals even the best images of Ceres ever taken by the Hubble Space Telescope. The video shows enough surface definition to discern its 9-hour rotation period. On target to...

    In the Darwin Debate, How Long Before the Tide Turns in Favor of Intelligent Design? Casey Luskin January 19, 2015 4:36 PM | Permalink A student emails me to ask how long it will be before the "tide turns from Darwinism to ID." He follows the debate over intelligent design and is aware that the Darwin lobby's rhetoric typically fails to address ID's actual arguments (which are scientific in nature), instead focusing on personal attacks or trying to claim ID is religion. This student feels it is obvious that ID has the upper hand in the argument, but wonders when...
  • Alexander-era tomb contains bones of woman, baby, men

    The culture ministry said research on the tomb's bones showed the buried woman was over 60 years old and about 1.57 metres tall while the two men were aged 35 to 45 years old. One of the men had cut marks in his left chest that were most likely from mortal injuries inflicted by a knife or small sword, the ministry said. The men had an estimated height of 1.62 to 1.68 metres. The few burned bone remains of the fifth interred person, who was cremated, could not reveal the person's gender and authorities said further testing would be carried...

    From eyewitness accounts of “trails of light” streaking across the sky to sightings of flying saucers, now amateur Mulder and Scullys alike can see if the truth really is out there by poring over almost 130,000 pages of declassified UFO documents that are now available online, reports MilitaryTimes.com. After spending decades filing Freedom of Information Act requests, John Greenewald, a UFO enthusiast, posted declassified records from Project Blue Book -- the U.S. Air Force’s records on alleged UFO and extraterrestrial sightings -- on an online database.

    The grant will allow the team to archaeologically survey the village using a variety of methods, with particular focus on the group of timber-framed buildings which are present on an estate map of 1631. Many of these buildings probably have their origins within the medieval period. Dr Nash said: "Based on place-name evidence, the village of Tilley probably has its origins during the Early Medieval (Anglo-Saxon) period. The 'ley' element of Tilley translates into 'leah', meaning wood clearing." The project, one of the largest of its kind, will include a dendrochronology survey of 28 buildings that stand within the Tilley...

    Ninety percent of the fats found in Neolithic cooking pots from Ireland came from dairy products, according to a new study conducted at the University of Bristol. "We know from previous research that dairying was an important part of many early farming economies, but what was a big surprise was the prevalence of dairy residues in Irish pots. It looks to have been a very important food source," said Jessica Smyth of the School of Chemistry. The remaining ten percent of the residues came from beef or mutton fat, or a mixture of milk and meat. "People can obviously cook...

    Explanation: The Great Nebula in Orion is an intriguing place. Visible to the unaided eye, it appears as a small fuzzy patch in the constellation of Orion. But this image, an illusory-color four-panel mosaic taken in different bands of infrared light with the Earth orbiting WISE observatory, shows the Orion Nebula to be a bustling neighborhood or recently formed stars, hot gas, and dark dust. The power behind much of the Orion Nebula (M42) is the stars of the Trapezium star cluster, seen near the center of the above wide field image. The orange glow surrounding the bright stars pictured...

    Massachusetts Institute of Technology scientists examining the intricate network of brain cells that underlie sight, thought, and psychiatric disease had a running joke in the laboratory: let’s just make everything bigger. If they could simply enlarge brain cells, they reasoned, the task of mapping the circuits would be easier. Now, they have found a way to do just that, using a technique that has shades of a 1950s science fiction movie. But instead of spawning killer ants or a 50-foot giantess, the researchers have found a controlled way to cause a tissue sample swell to roughly four and a half...

    We were recently informed by the blaring of progressive trumpets and flapping of angelic wings that evil energy users had set a new record, with 2014 being the warmest year in recorded history. The end is clearly near, so you should all begin getting your affairs in order unless President Obama can rail through his new methane regulations. It is, as Mother Jones described it, a moment of truth. Well folks, what can I say? We had a good run.But wait! The phrase “moment of truth” ends with a rather important word. How “true” is this claim? The folks...

    On January 16 The New York Times reported the lies NASA keeps telling about global warming with an article titled “2014 Breaks Heat Record, Challenging Global Warming Skeptics.” We have reached the point where neither a famed government agency nor a famed daily newspaper can be believed simply because both are lying to advance the greatest hoax of the modern era. Remember that 2014 started off with something called a “polar vortex” to describe the incredibly cold weather being experienced and remember, too, that we were being told that it was evidence of global warming! That’s how stupid the “Warmists”...
