Over the past 19 years, the Cassini orbiter has explored Saturn and its complex system of rings and moons. On Sept. 15, 2017, after its final orbit, Cassini will plunge into Saturn’s atmosphere, burn up like a meteor, and become part of the planet itself. In order to avoid the unlikely possibility of Cassini someday colliding with one of these moons, NASA has chosen to safely dispose of the spacecraft in the atmosphere of Saturn. The spinning vortex of Saturn's north polar storm resembles a deep red rose of giant proportions surrounded by green foliage in this false-color image.
Climate change activists have been wringing their hands ever since Inauguration Day, fearing that the new administration would do something just like this. The webpage, which has been in existence for more than 20 years, explained what climate change is, what caused it and how it affects your health, among other things.
The United States of America has a major problem, and I’m not just talking about Donald Trump here. A new report by the National Academies of Science, Engineering and Medicine has revealed that out of the 169 hazardous volcanoes in the US, just under half of them are being monitored. That means a good swath of the 321.4 million American populace is at risk of a volcano dumping some pyroclastic flows or lava bombs on their heads and they won’t get much of a warning. If this sounds bad, then you’re right – it is. The US would be put to shame by Japan here, a highly volcanic country that has comprehensively covered its volcanoes in seismometers and volatile sensors, while also using satellites to
Brasília (AFP) - Fed up with endless encroachment on their ancestral lands, leaders of Brazil's many indigenous tribes went to the capital Brasilia to speak out this week. "They're prejudiced," said Alvaro Tucano, one of the tribal members taking part in a week-long camp outside the government complex.
The idea of augmenting humans with machine intelligence for their own protection may be a new one, but research into how the brain records sensory input and uses it to drive physical responses is "an outlandishly difficult problem" that people have been working on since the 1960s, Pruszynski says. There are two big challenges with the research: first, accurately recording the brain's neural activity to know which parts are being used to record outside stimuli; second, figuring out how the brain sends the resulting signals out to the peripheral nervous system, which allows a person to move an arm, leg or other body part. "Trying to get accurate info out of the brain is very difficult," says Pruszynski. Bradley Wyble, an associate professor of psychology at Penn State University who's studied how the brain turns visual stimuli into ideas, agrees.
The pope urged compassion alongside progress in a surprise TED Talk shown in Vancouver, British Columbia, yesterday (April 25). In the first-ever TED Talk by a pope, Pope Francis urged a science- and tech-heavy audience to cultivate love and tenderness. According to TED's international curator, Bruno Giussani, it took more than a year to arrange the talk.
Turkey passed two new decrees Saturday — one that expelled more than 4,000 civil servants and another that banned television dating programs. The country's Official Gazette published the decrees Saturday evening. The first named thousands of civil servants to be dismissed, including nearly 500 academics and more than 1,000 Turkish military personnel.
A group of amateur sky watchers in Alberta, Canada just helped scientists discover a new celestial phenomenon and since nobody knows exactly what it is yet, they've taken to calling it Steve. Members of the Alberta Aurora Chasers Facebook group have been taking photos of this bright purple streak of light in the skies over Canada for several years now, thinking it was a kind aurora called a proton aurora.
Origami is an old Japanese art of folding paper into various decorative shapes, and requires a certain amount of nimbleness of the fingers. The self-folding origami technique was developed by researchers from Georgia Institute of Technology and Peking University in China, who published a paper on the subject Friday in the journal Science Advances. The paper, titled “Origami by frontal photopolymerization,” explains the method.
Scientists have launched an investigation into the unexplained deaths of 41 humpback whales along the Atlantic coast of the United States, the National Oceanic and Atmospheric Administration announced Thursday. Researchers declared the ongoing phenomenon that’s affected whale populations stretching from Maine to North Carolina since the start of 2016 an “unusual mortality event.” About 14 whales usually die in the region annually ― but they documented 26 deaths in 2016 and nine this year. NOAA said it doesn’t yet have a concrete reason why all of the animals have died. The agency conducted necropsies on 20 whales, and 10 appeared to have been struck and killed by ships.

China will begin construction of a permanent manned space station in 2019 after carrying out a successful in-orbit refuelling from its Tianzhou-1 cargo spacecraft, officials leading the project said on Friday. The Tianzhou-1, China's first cargo spacecraft, launched on April 20 and completed the first of three planned docking attempts with the orbiting Tiangong-2 spacelab two days later, state media reported. The successful five-day refuelling, directed from technicians on Earth and completed on Thursday, is a key milestone toward China's plans to begin sending crews to a permanent space station by 2022.
CAPE CANAVERAL, Fla. — The U.S. Postal Service is going all out for this summer's total solar eclipse, with a first-of-its kind stamp. Just touch the stamp with your finger, and the heat transforms the image of the blacked-out sun into the moon. Remove your finger, and the eclipse reappears. The trick is using temperature-sensitive ink. The ink is vulnerable to UV light; ironically, that means that the stamp should be kept out of direct sunlight to preserve the special effect, the U.S. Postal Service warned. There's a map on the back of the stamp sheet showing the diagonal path the solar eclipse will take across the United States on Aug. 21, as the moon covers the sun in the sky. It will be
It is now more than three years since Malaysia Airlines flight MH370 disappeared, and there is growing evidence that the search authorities have been looking for the aircraft in the wrong place. An underwater search of a 120,000 square kilometer area of the Indian Ocean, off Western Australia, has so far failed to find any evidence of the crash site. Initial evidence on the aircraft flight path was through satellite data (SatCom) from Inmarsat.
The sorrow of the March for Science did not hit me until I saw a photo from it—an older woman standing next to a homemade sign adorned with Ms. Frizzle. You know Ms. Frizzle, if only from a PBS ad. She is the elementary-school teacher with the curly red hair at the center of the Magic School Bus books and television show. In every episode, Ms. Frizzle corrals her small class of diverse kids into the Magic School Bus, which then drives to a local swamp, volcano, or human circulatory system. Then the eponymous magic happens—and the entire class is outfitted in hip waders, floating past a great blue heron; or in SCUBA suits, swimming through a vein past a red blood cell. Ms. Frizzle—not until recently
Were Superman a building-safety inspector, he’d probably use his powers to pull off something similar to this new technique invented by researchers at the National Institute of Standards and Technology (NIST). “Corrosion of steel, aka rust, is a huge problem worldwide, and costs the U.S. alone over $300 billion per year in prevention and repair,” Dr. Edward Garboczi, an NIST fellow in the applied chemicals and materials division, told Digital Trends. “This includes corrosion of pipes in a chemical plant, corrosion of steel reinforcing bars in a concrete bridge deck, corrosion of a steel bridge, corrosion of automobile bodies, and many other examples.
A coal-export terminal proposed in Washington state would increase cancer risks for some residents, make rail accidents more likely and add millions of metric tons of climate-changing greenhouse gas globally every year, according to an environmental study released Friday. The yearslong fight over the deep-water port comes as President Donald Trump has vowed to revive the struggling coal industry and lifted restrictions on mining coal and drilling for oil and natural gas. Environmentalists, tribes and others have fiercely opposed the project, which could increase U.S. exports of coal by 40 percent, because of concerns about global warming, coal dust pollution and potential damage to fisheries on the river.

The source of Antarctica's gruesome looking Blood Falls has finally been discovered putting an end to the mystery of where the red water came from. At first it was thought some form of algae was discolouring the water, but that hypothesis was never verified
The Saturn V rocket that took astronauts to the moon still holds the record for being the largest, heaviest rocket to ever blast off for the stars. It's only fitting that the new Lego kit to commemorate it is giant as well. Standing 39 inches tall with 1,969 pieces (get it?), the Lego Saturn V is a mammoth model complete with three removable rocket stages, a lunar lander, lunar orbiter, and three Lego astronauts in an all-new style. The Lego Saturn V will be available this June for $120.
A 508-million-year-old critter — one that looks like a weird lobster with 50 legs, two claws and a tent-like shell — is the oldest known arthropod with mandibles on record, a new study finds. Arthropods are a group of invertebrates that includes spiders, insects and crustaceans. Many arthropods, including flies, ants, crayfish and centipedes, have mandibles — appendages that can grasp, crush and cut food.
Sergio Canavero, a controversial professor and neurosurgeon, wants to perform the first human head transplant in December. He told German magazine OOOM that the procedure will take place in China. According to the Observer, it will take 80 surgeons, 36 hours and $10 million to execute. Like a sci-fi tale come to life, Canavero, who’s also the former director of the Turin Advanced Neuromodulation Group, claims that people whose brains have been cryogenically frozen could be revived within three years. “At the moment, I can only disclose that there has been massive progress in medical experiments that would have seemed impossible even as recently as a few months ago,” Canavero told OOOM. His announcement

April 28 (UPI) -- Scientists have found a way to identify the DNA of early human relatives, the Denisovans and Neanderthals, among ancient cave sediments. The method doesn't require the presence of human remains. Evidence of the presence of early human relatives -- stone tools, carved bones and more -- has been found throughout Europe and Asia. But actual hominid remains are relatively rare. The new method could help scientists conduct more comprehensive genomic analysis of early human relatives. "We know that several components of sediments can bind DNA," Matthias Meyer, a researcher at the Max Planck Institute for Evolutionary Anthropology, said in a news release. "We therefore decided to investigate
"We need to build a system that allows us to feed the population in a much more efficient manner," says James Rogers, CEO of Apeel Sciences. It's about better utilizing the food that we already grow--a tremendous amount of which ends up spoiling before it ever reaches consumers. The U.N.'s Food and Agriculture Organizations estimates that the global cost of food waste is a whopping $2.6 trillion per year.
