    Scientists Bid Farewell to Rosetta Space Probe Before Crash

    Scientists began saying their final farewells to the Rosetta space probe Thursday, hours before its planned crash-landing on a comet, but said that data collected during the mission would provide discoveries for many years to come. The spacecraft, launched in 2004, took a decade to reach comet 67P/Churyumov-Gerasimenko, where it released a smaller probe called Philae that performed the first comet landing in November 2014. With almost two dozen scientific instruments between them, Rosetta and its lander gathered a wealth of data about 67P that have already given researchers significant new insights into the composition of comets and the formation of celestial bodies. "The best thing is we still haven't gone through all our data," said Mohamed El-Maarry, a researcher at the University of Bern, Switzerland.

    A congressman doesn't want SpaceX handling its own 'troubling' rocket accident investigation

    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. "Both SpaceX failures occurred after the Air Force certified the Falcon 9 launch vehicle for U.S. national security launches, less than fifteen months

    Tough times for S.Africa's all-female anti-poaching unit

    South Africa's all-female "Black Mambas" anti-poaching team had never lost a rhino since they were formed in 2013, but the killing of two animals earlier this month shattered their proud record. The two rhinos, one of which was pregnant, were shot dead and their horns hacked off by poachers on a full moon night, underlining the crisis that threatens the species. The Black Mambas are made up of 36 unarmed female rangers, aged from 19 to 33, based at the Balule Game Reserve in Limpopo province on the edge of Kruger National Park.

    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.

    Space farms could feed Musk’s mission to colonize Mars

    Scientists are making strides in growing food in space, and their efforts could be critical to eventually supporting a permanent human colony on Mars. "We can grow plants on Mars just by compressing the atmosphere," SpaceX founder and CEO Elon Musk said Tuesday in a long-awaited speech detailing his vision for sending humans to Mars by 2025. NASA has a stated goal for a manned Mars mission in the 2030s.

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.

    Mission accomplished: Rosetta probe crash-lands on comet

    Cheers erupted at the European Space Agency on Friday as the Rosetta spacecraft — which traveled 4 billion miles over the course of a decade — made a crash-landing onto the icy comet it has been orbiting for the past two years. It also ended Rosetta's run as an orbiter. "Today, we got more out of this mission than we ever thought," said Gerhard Schwehm, who was Rosetta's mission manager until his retirement in 2014.

    On a Northern Lights night, Iceland dims the lights to admire nature's own (+video)

    The Aurora Borealis, or Northern Lights, are among the most breathtaking spectacles of the natural world. When it came time to catch a glimpse, Icelanders weren’t about to let a little light pollution get in their way. So on Wednesday night, the streets of Reykjavik went dark. The blackout was a deliberate move by city officials, who hoped to cut light pollution and give residents a better view of the aurora. It was also a rare moment of recognition for the issue of light pollution, which affects more than 80 percent of the world’s population. “Switching off the street lights was a great gesture by the city council,” astronomy educator Saever Helgi Bragason told the BBC. “I hope this will be

    The worker shortage facing America's farmers

    American farmers say they are facing a severe worker shortage. More than half of U.S. farm workers are undocumented immigrants, according to the U.S. Department of Labor. Yet, that pool of workers is shrinking. A recent Pew Research report found that more Mexican immigrants are now leaving the U.S. than coming into the country, citing tougher enforcement of immigration laws and the slow economic recovery here in the U.S. (The report accounted for both documented and undocumented immigrants). With fewer workers, farm owners say costs are rising and they often must leave unpicked fruit to rot in the fields. Many producers are even opting to leave the U.S. for countries with lower costs and fewer

    Colombia peace deal will allow scientists to uncover country's unexplored biodiversity

    BOGOTA, COLOMBIA –  In 2004, scientist Diego Alarcón ventured into the Colombian mountains to study bird species in a place most scientists wouldn’t dare go: territory controlled by FARC rebels. Scientists studying Colombia’s rich biodiversity are among many celebrating the August announcement of a permanent ceasefire between the Colombian government and FARC rebels. After decades of limited access to Colombia’s most biodiverse areas, researchers can finally explore and document the plants, animals and microorganisms that make Colombia the second most biodiverse country in the world. One expedition by the Humboldt Institute has already uncovered more than 100 new species in conflict zones.

    Get ready for the great 'black moon' of 2016

    While rare and unusual celestial events are generally a good reminder to get outside and look up into the heavens, the one happening Friday isn't exactly a showstopper. In fact, good luck seeing anything at all. On the evening of Sept. 30, the Western Hemisphere will be treated to a "black moon," the rare second occurrence of a new moon in a single calendar month. New moons, or dark moons, are when the side of the moon lit up by the sun is facing away from Earth, making it nearly invisible to the naked eye. These generally happen only once during the moon's 29.5-day lunar cycle around the Earth. Roughly every 2.5 years, however, a single month features two new moons, with the second instance

    What Meerkat Murder Tells Us About Human Violence

    A new study of violent behavior in more than 1,000 mammal species found the meerkat is the mammal most likely to be murdered by one of its own kind. The study, led by José María Gómez of the University of Granada in Spain and published Wednesday in the journal Nature, analyzed more than 4 million deaths among 1,024 mammal species and compared them with findings in 600 studies of violence among humans from ancient times until today. The findings tell us two things: Some amount of violence between humans is attributable to our place on the evolutionary tree. Meerkats are surprisingly murderous. To be clear, the study's authors did not set out to prove (or disprove) a theory of meerkat violence;

    Why birds never crash into each other in midair

    Birds always seem to avoid one another, even if they're flying on what looks like a collision course. The researchers looked at 10 birds, specifically parakeets or "budgies." They set the birds up on opposite ends of a tunnel and went through 102 rounds of flights. "As air traffic becomes increasing busy, there is a pressing need for robust automatic systems for manned and unmanned aircraft, so there are real lessons to be learned from nature," study author Mandyam Srinivasan said in a news release.

    Feminist PhD Candidate: Science Is Sexist Because It's Not Subjective

    College science classes are hostile to women and minorities because they use the scientific method, which assumes people can find reliable truths about the natural world through careful and sustained experimentation, concludes a recent dissertation by a doctoral candidate at the University of North Dakota. Laura Parson, a student in the university’s education department, reviewed eight science class syllabi at a “Midwest public university” and said she discovered in them a hidden hostility to women and minorities: Initial exploration of the STEM syllabi in this study did not reveal overt references to gender, such as through the use of gendered pronouns. However, upon deeper review, language

    After 170 Years, Remains of US Troops Return From Mexico

    Remains thought to be those of U.S. troops who died in the Mexican-American War have been flown to a military mortuary in Delaware in an effort to determine whether they belonged to militia members of a Tennessee regiment known as "The Bloody First." An Army twin-engine turbotrop bearing two aluminum cases topped by American flags arrived Wednesday afternoon at Dover Air Force Base, home to the nation's largest military mortuary. White-gloved members of the 3rd Infantry "Old Guard" unit, which stands vigil at the Tomb of the Unknowns in Arlington National Cemetery near the nation's capital, solemnly transferred the cases to a vehicle bound for the mortuary.

    Global warming set to pass 2C threshold in 2050: report

    Earth is on track to sail past the two degree Celsius (3.6 degrees Fahrenheit) threshold for dangerous global warming by 2050, seven of the world's top climate scientists warned Thursday. "Climate change is happening now, and much faster than anticipated," said Sir Robert Watson, former head of the UN's Intergovernmental Panel for Climate Change (IPCC), the body charged with distilling climate science for policy makers. Since 1990, devastating weather-related events -- floods, drought, more intense storms, heat waves and wild fires -- due to climate change have doubled in number, Watson and the other scientists said in a report.

    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.
