    By the Numbers: 12 Years Chasing a Comet

    It's been 4,595 days since the Rosetta space probe was lifted into orbit on the first stage of its 12-year mission to chase down comet 67P/Churyumov-Gerasimenko. Here is a look at some of the other numbers, big and small, surrounding the mission: SPACE ODYSSEY As journeys go, this one was epic. According to the European Space Agency the Rosetta probe has travelled some 7,971,290,298 kilometers (4,953,359,791 miles) during its lifetime — almost 21,000 times the distance from the Earth to the moon. HIGH-SPEED CHASE In order to catch up with a comet the Rosetta probe had to swing around Earth and Mars, using the planets' gravity to pick up speed. That's because 67P is flying through space at a breathtaking

    Rare 'Black Moon' Rises Over Western Hemisphere Friday Night

    A rare "black moon" rises Friday night over the Western Hemisphere, but don't expect to see it. NASA says a black moon is the second new moon in a calendar month. A new moon is the start of the lunar cycle and the phase where the moon is impossible to see because it's completely shrouded in darkness. A black moon occurs about once every 32 months. Friday night's officially takes place at 8:11 p.m. on the East Coast. The term "black moon" contrasts with "blue moon," which is the second full moon in a calendar month.

    'World's deepest flooded cave' discovered in Czech Republic

    A Czech-Polish team said Friday it had discovered the world's deepest underwater cave in the eastern Czech Republic. At 404 metres (1,325 feet) deep, the Hranicka Propast, a limestone abyss near the city of Hranice, beats out Italy's Pozzo del Merro cave that is 392 metres deep for the world record, Miroslav Lukas of the Czech Speleological Society told AFP.

    House Republicans don't want SpaceX investigating its own 'troubling' rocket accidents

    Just days after SpaceX founder Elon Musk delivered his sweeping vision of colonizing Mars, a Colorado congressman is calling on government agencies to take over an investigation of the aerospace company's recent launchpad rocket explosion. The move — a signed congressional letter dated Thursday, September 29 — follows on the heels of two recent explosions of uncrewed Falcon 9 rockets. "These failures could have spelled disaster, even loss of life, had critical national security payloads or NASA crew been aboard those rockets," the letter states.

    Beijing's silver-plated 'Smog Free Tower' turns pollution into carbon cubes

    Beijing residents are all too familiar with air pollution. On high pollution days, dense smog permeates the sky, contaminates the streets, and of course is breathed into people’s lungs. The tower is part of the Smog Free Project, a clean air initiative led by Dutch artist and designer Daan Roosegaarde, who bills the structure as “the largest electronic vacuum cleaner in the world.” Stationed in parks, the tower creates a bubble of clean air in otherwise polluted areas.

    The Surprising Health Benefit of Riding Roller Coasters

    Riding a roller coaster could be beneficial for passing kidney stones. After patients came back from Disney World, a urologist at Michigan State University noticed an interesting pattern: Those who rode medium-intensity roller coasters came back with fewer kidney stones. In fact, one patient told the doctor that he passed a kidney stone every single time he rode Big Thunder Mountain roller coaster.

    Why Mars’ Job Market Could Be About to Take Off

    Elon Musk unveiled his plan to get the human race to Mars on Tuesday, but the question remains, why would anyone want to go? One reason Musk gave was that it will be a great place to find work. Robert Zubrin, an aerospace engineer and president of the Mars Society who likes to use European colonization of the Americans as a guide to how a Martian colonization might work, points out that European immigrants to New England and Virginia went there in search of gold and silver. They found none of those metals, as is likely to be the case with Mars, but instead were able to sustain themselves through agriculture, and in the case of Virginia eventually found a viable export in tobacco.

    The black moon has a long, interesting history that greatly involves October

    Black Moons (and more broadly, new moons) have a long history of special meaning in many cultures and practices, and interestingly, it’s often connected to women! Right off the bat, if you look at a list of lunar deities, you’ll notice that the vast majority of them are female, which is kind of cool and interesting, especially since the moon holds such power in many cultures. Much like the blue moon, it’s just a colloquial name given to what is, in the grand scheme of things, a fairly mundane celestial event.

    Reptile With 'Bizarre' Limbs Tweaks Current Understanding of Evolution

    A new study on 212-million-year-old fossils from an extinct reptile with strange arms has shed new light on our understanding of evolution. A team of scientists analyzed the fossils of a drepanosaurus, a prehistoric reptile that has been described as a "chameleon-anteater hybrid," and found that the bone structure, especially in the front limbs, were unlike any other animals from that time period. “This animal stretches the bounds of what we think can evolve in the limbs of four-footed animals,” Adam Pritchard, the lead author on the paper and a postdoctoral researcher at Yale University, said in a statement.

    Researchers Sample Unusually Rich Deep-Sea Area off Hawaii

    Federal researchers have just returned from an expedition to study the biodiversity and mechanisms of an unusually rich deep-sea ecosystem off the coast of Hawaii's Big Island. Scientists with the National Oceanic and Atmospheric Administration told The Associated Press in a telephone interview Thursday that the abundance of sea life sampled in a particular stretch of water off the Big Island points to a thriving deep-sea habitat, but they aren't exactly sure why. The area, about a mile off the south shore of Hawaii Island, was full of fish including sawtooth eels, dragonfish and many other mysterious deep-sea creatures. Much of the ocean surrounding Hawaii is among the least productive water in the Pacific, said the expedition's lead researcher Jamison Gove, a NOAA oceanographer.

    One of the only nuclear fusion reactors in the U.S. just broke

    It’s not that often that we hear about major breakthroughs in nuclear research, and now such announcements, at least in the U.S., may become more infrequent. Researchers at the Princeton Plasma Physics Laboratory (PPPL) in New Jersey are now trying to determine what exactly was behind the reactor’s failure, which could turn out to be a lengthy engagement. The real travesty of the situation is that it means the U.S. has only one major facility in which to conduct nuclear fusion experiments.

    The boy spent much of his early childhood enduring Serbian traditions, including an overabundance of sloppy kisses from two wrinkly old aunts, one of whom had “two teeth protruding like the tusks of an elephant,” Nikola Tesla wrote in his autobiography. Recognized as one of the greatest inventors of his time, his celebrity status saw him hobnobbing with the likes of Mark Twain, Rudyard Kipling, Thomas Edison and J.P Morgan. “It’s a word that is overused, but he really was a genius and a star among the stars,” says Marc Seifer, author of the biographical account of the engineer, Wizard: The Life and Times of Nikola Tesla.

    US Military Research Labs will take commercial technology for a constant game changing third offset innovation

    First offset - nuclear weapons In the Cold War, the U.S. and its NATO allies sought a series of competitive advantages over the Soviet Union, a means by which to offset their very, very great conventional strength. The United States actually pursued two offset strategies. The first came with President Eisenhower's New Look Strategy in the early 1950s. When President Eisenhower came into office in 1953, the United States was heavily outnumbered by the Soviet conventional superiority on the European central front. Eisenhower estimated it would take 92 U.S. and NATO divisions to have any chance of checking, at the time, 175 Soviet divisions. But a force that size, with Europe rebuilding itself after

    SpaceX's Elon Musk turns to science fiction for Mars ship

    CAPE CANAVERAL, Fla. (AP) — If SpaceX founder Elon Musk’s plan to establish a city on Mars sounds like science fiction, then consider the name of his first passenger ship. The answer lies in “The Hitchhiker’s Guide to the Galaxy,” the comic series about Earth’s last surviving man. Musk is leaning toward the name “Heart of Gold,” the starship from the novel with Infinite Improbability Drive. The name generated applause Tuesday at the International Astronautical Congress in Mexico. That’s where he provided details of his bold plans to fly humans to Mars and set up a self-sustaining city with 1 million people. For the past decade, Musk has borrowed from science fiction and fantasy when naming his

    5 Decisions That Made the Nobel Prizes Look Bad

    Nobel Prizes cannot be revoked, so the judges must put a lot of thought into their selections for the six awards, which will be announced in the next two weeks. A discovery might seem groundbreaking today, but will it stand the test of time? Prize founder Alfred Nobel wanted to honor those whose discoveries created "the greatest benefit to mankind." Here are five Nobel Prize decisions that, in hindsight, seem questionable: — When a German who organized poison gas attacks won the chemistry prize. Fritz Haber was awarded the 1918 chemistry award for discovering how to create ammonia from nitrogen and hydrogen gases. His method was used to manufacture fertilizers and delivered a major boost to agriculture

    Open office spaces look cool and offer a more open workspace, but disruption and lack of privacy are ongoing issues. Inspired by a conversation with Google, MIT’s Self-Assembly Lab designed a drop-down cubicle that creates a private meeting area in open space, according to ZDNet. The Transformable Meeting Space can be installed in existing open office spaces or factory floors without significant structural or electromechanical requirements.

    How weak DNA evidence railroaded—and then rescued—Amanda Knox

    Today, September 30, Netflix releases its original documentary, Amanda Knox. The film features the now exonerated suspects and the prosecutor who charged them as the piece looks back at a murder trial that grabbed headlines worldwide. As such, we're resurfacing our piece from October 2011 that examined how DNA evidence put Knox in jail before ultimately rescuing her. If you watch crime dramas, you'll be forgiven for the impression that DNA evidence makes an airtight case. And if you do have that impression, you might be confused about the internationally famous case of American Amanda Knox, convicted of murdering her British roommate in Perugia, Italy in 2007. After all, the prosecution's case

    Humans Are Natural Killers, But We'Re Not The Worst

    Violence comes naturally to humans, but we are far less murderous than we used to be, a new study shows. Scientists in Spain who examined the tendency among more than 1,000 mammal species to kill their own found that humans have been "particularly violent" throughout our history, reports the AP. Early humans killed each other at a rate of about 20 in 1,000, but got more violent during the Middle Ages when the rate shot up to 120 in 1,000. After studying 600 human populations from the Stone Age to the present day, the researchers concluded that "lethal violence is part of our evolutionary history but not carved in stone in ‘our genes,’” lead author Jose Maria Gomez tells the Guardian.

    Monsanto-Funded Study Says Monsanto’s Weed Killer Doesn’t Cause Cancer

    If you’ve been worried ever since the world’s leading body of cancer experts designated the most heavily used herbicide in the history of modern agriculture a probable human carcinogen, take heart: Four “independent expert panels” have reviewed the science and determined it’s unlikely the chemical, a cash cow for agrochemical giant Monsanto, poses a carcinogenic risk to humans at all. In this case, readers have to scroll aaaallll the way down to the “Declaration of Interest” to find out that, sure enough, the study was bought and paid for by Monsanto. The chemical in question is glyphosate, though you may know it better as the active ingredient in Monsanto’s blockbuster-selling herbicide Roundup.

    Research suggests humans occupied the Americas earlier than previously thought

    Ancient artifacts found at an archeological site in Argentina suggest that humans occupied South America earlier than previously thought. Approximately 13,000 years ago, a prehistoric group of hunter-gathers known as the Clovis people lived in Northern America. Previous research suggests that the Clovis culture was one of the earliest cultures in the Americas. However, more recent research from the Pampas region of Argentina supports the hypothesis that early Homo sapiens arrived in the Americas earlier than the Clovis hunters did. The evidence for earlier human arrival in the Americas comes from a rich archaeological site in southeastern South America called Arroyo Seco. A group of scientists

    How Do Photons Experience Time?

    Traveling at the speed of light, photons emitted by the Sun take a little over eight minutes to reach the Earth. The 93 million mile (150 million km) journey across the expanse of empty space is no obstacle to this light, but it means that when we look at the Sun, we’re seeing it as it was a short time in the past, not as it is instantaneously from our perspective. If the Sun were to wink out of existence right now, we wouldn’t know it — not from its light, not from its gravity — until eight minutes later. But what about from the photon’s point-of-view? We know that if you travel close to the speed of light, Einstein’s theory of special relativity kicks in, and time dilates while lengths contract.
