Rebecca Hersher, reporting for NPR: Hurricane Florence is moving relentlessly toward the Southeastern U.S. It's a large, powerful cyclone that will likely bring storm surge and high winds to coastal communities. But climate scientists say one of the biggest threats posed by Florence is rain. "Freshwater flooding poses the greatest risk to life," explains James Kossin, an atmospheric scientist for the National Oceanic and Atmospheric Administration and the University of Wisconsin, Madison. And Florence could cause extensive freshwater flooding for two reasons. First, Florence is moving slowly, and could all but stop when it reaches land. "The storm could be over North Carolina and traveling incredibly slowly -- on the order of just a few miles per hour," explains Kossin, who says an official from the city of Charlotte, N.C., contacted him about rainfall projections for that city.

If Florence stalls over the Southeast, it would be reminiscent of Hurricane Harvey, which spent days dumping rain on the Houston region last year. Some areas ended up with more than 60 inches, a catastrophic amount of water that shut down the entire region and resulted in at least 93 deaths. Slow-moving storms like Harvey are getting more common. A study published earlier this year by Kossin found that tropical cyclones around the world have slowed down 10 percent in the last 70 years. "We're seeing that in every ocean basin except the northern Indian Ocean," says Kossin, possibly because climate change is causing the wind currents that hurricanes ride to slow down. If Florence slows down and stalls when it hits land, it will the latest example of that trend. Kevin Trenberth of the National Center for Atmospheric Research in Boulder, Colo., says global warming also affects the size and intensity of storms like Florence.

According to a new report from Bankrate, actuarial science, the formal term for the study of insurance, was ranked the most valuable college major.

"The actuarial science profession is interesting because students don't need advanced degrees to gain livable wages, but instead are certified through a series of exams overseen by the industry's professional organizations," said Bankrate.com analyst Adrian Garcia in an interview. "Students typically pass one to two of these exams while in school and then go on and complete others while working, earning raises and bonuses as they pass." Bloomberg reports: Actuarial science majors earn an average annual salary of $108,658 and have a better-than-average unemployment rate at 2.3 percent. And at a time when student debt is at a record high, these graduates are less likely to incur the added expense of additional schooling and delayed earning potential. Less than 1 in 4 graduates pursue advanced degrees. The study ranked 162 majors with labor forces of at least 15,000 people based on average annual income, employment status and whether those graduates went on to pursue a higher degree within 12 months. Income accounted for 70 percent of the weighted ranking, unemployment for 20 percent and 10 percent was awarded to career paths that did not demand additional education. The data was derived from the U.S. Census Bureau's 2016 American Community Survey.

schwit1 shares a report from Alabama Local News: NASA's administrator Jim Bridenstine has directed the space agency to look at boosting its brand by selling naming rights to rockets and spacecraft and allowing its astronauts to appear in commercials and on cereal boxes, as if they were celebrity athletes. While officials stress that nothing has been decided, the idea could mark a giant cultural leap for the taxpayer-funded government agency and could run into ethics regulations that prevent government officials from using public office for private gain.

"Is it possible for NASA to offset some of its costs by selling the naming rights to its spacecraft, or the naming rights to its rockets," Bridenstine said. "I'm telling you there is interest in that right now. The question is: Is it possible? The answer is: I don't know, but we want somebody to give us advice on whether it is." He also said he wanted astronauts to be not only more accessible to journalists but even to participate in marketing opportunities to boost their brands - and that of the space agency. "I'd like to see kids growing up, instead of maybe wanting to be like a professional sports star, I'd like to see them grow up wanting to be a NASA astronaut, or a NASA scientist," he said. "I'd like to see, maybe one day, NASA astronauts on the cover of a cereal box, embedded into the American culture."

Antarctica has become the best-mapped continent on Earth with a new high-resolution terrain map showing the ice-covered landmass in unprecedented detail. From a report: According to the scientists at Ohio State University and the University of Minnesota who created the imagery, Antarctica is now the best-mapped continent on Earth. The Reference Elevation Model of Antarctica (REMA) was constructed using hundreds of thousands of satellite images taken between 2009 and 2017, Earther reports. A supercomputer assembled the massive amounts of data, including the elevation of the land over time, and created REMA, an immensely detailed topographical map, with a file size over 150 terabytes. The new map has a resolution of 2 to 8 meters, compared to the usual 1,000 meters, says an Ohio State press release. According to The New York Times, the detail of this new map is the equivalent of being able to see down to a car, or smaller, when before you could only see the whole of Central Park. Scientists now know the elevation of every point of Antarctica, with an error margin of just a few feet.

A nonprofit has deployed a multimillion-dollar floating boom designed to corral plastic debris littering the Pacific Ocean (Warning: source may be paywalled; alternative source). The 2,000-foot-long structure left San Francisco Bay on Saturday. According to The New York Times, Ocean Cleanup "aims to trap up to 150,000 pounds of plastic during the boom's first year at sea." From the report: Within five years, with the creation of dozens more booms, the organization hopes to clean half of the Great Pacific Garbage Patch. Over the next several days, the boom will be towed to a site where it will undergo two weeks of testing. If everything goes as planned, the boom will then be brought to the garbage patch, nearly 1,400 miles offshore, where it is expected to arrive by mid-October, said Boyan Slat, 24, the Dutch inventor and entrepreneur who founded Ocean Cleanup.

The cleanup system is supposed to work like this: After the boom detaches from the towing vessel, the current is expected to pull it into the shape of a "U." As it drifts along, propelled by the wind and waves, it should trap plastic "like Pac-Man," the foundation said on its website. The captured plastic would then be transported back to land, sorted and recycled. The boom has an impenetrable skirt that hangs nearly 10 feet below to catch smaller pieces of plastic. The nonprofit said marine life would be able to pass underneath.

An anonymous reader quotes a report from Digital Trends: The first unmanned and autonomous sailboat has successfully crossed the Atlantic Ocean, completing the journey between Newfoundland, Canada, and Ireland. The 1,800 mile journey took two and a half months. It was part of the Microtransat Challenge for robotic boats, and bolsters the possibility of unmanned boats being used for long-haul missions. This could include everything from ocean research to surveillance. "This has never been done before," David Peddie, CEO of Norwegian-based Offshore Sensing AS, which built the vessel, told Digital Trends. "The Sailbuoy [robotic boat] crossed this distance all by itself without incident. The significance of this is that it proves that one can use unmanned surface vehicles to explore the oceans for extended periods and distance. This greatly reduces the cost of exploring the oceans, and therefore enables a much more detailed knowledge of the oceans than is possible using conventional manned technology."

According to Peddie, the journey was surprisingly uneventful when it came to dealing with major challenges. That's a significant departure from the 20 previous unsuccessful efforts made by teams trying to complete the challenge since it started in 2010. "We had to wait a while for the right wind conditions to deploy safely; otherwise, the crossing has been normal with not too much wind and waves," he said. "We had to avoid some oil platforms, but this is not unusual since we test in the North Sea." He also noted that an effort was made to stay away from other ships, since there was a risk that the boat may have been picked up by passing traffic. Sailbuoy ships cost $175,000 each and are powered by on-board solar panels. They send constant GPS data to reveal exactly where they are located.

A Dubai-based engineering firm is planning to tow an iceberg from Antarctica to help provide fresh drinking water to the desert city's rapidly-growing population. Stuff.co.nz reports: The National Advisor Bureau (NABL), a private engineering firm, wants to schlep a glacial iceberg from Antarctica -- weighing approximately 100 million tons -- to Dubai, via an intermediate stop in either Perth, Australia, or Cape Town, South Africa. If the iceberg doesn't melt along the way, the firm will sell the water to Dubai's government. Dubai, which is the most populous city in the United Arab Emirates, is growing so rapidly that a solution to the city's looming water crisis must be found, according to the city's largest English-language newspaper, The Khaleej Times.

The company is beginning a pilot study in November to examine the feasibility of the iceberg-towing project. According to Alshehi, the firm will use satellite imagery to look for a suitable iceberg -- which he says should be between 2000 feet (609 meters) and 7000 feet (2.1 kilometers) long -- and then try and tow it to either Australia or South Africa. Once the iceberg gets to its first stop, it will be towed the rest of the way. Because icebergs are so heavy, the company will need multiple ships to assist with towing, and it will use the ocean's prevailing currents to their advantage. Alshehi told NBC that even if 30 percent of the iceberg melts on the journey, it will still be able to provide between 100 million and 200 million cubic meters of fresh water -- enough for 1 million people to stay hydrated for five years. Last month, Alshehi told NBC: "If we succeed with this project, it could solve one of the world's biggest problems. So if we show this is viable, it could ultimately help not only the UAE, but all humanity."

An anonymous reader quotes a report from Medical Xpress: Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found one of the answers -- mindfulness. The researchers analyzed data obtained from a study published in 2015 that compared mindfulness meditation to placebo analgesia. In this follow-up study, Zeidan sought to determine if dispositional mindfulness, an individual's innate or natural level of mindfulness, was associated with lower pain sensitivity, and to identify what brain mechanisms were involved. In the study, 76 healthy volunteers who had never meditated first completed the Freiburg Mindfulness Inventory, a reliable clinical measurement of mindfulness, to determine their baseline levels. Then, while undergoing functional magnetic resonance imaging, they were administered painful heat stimulation.

Whole brain analyses revealed that higher dispositional mindfulness during painful heat was associated with greater deactivation of a brain region called the posterior cingulate cortex, a central neural node of the default mode network. Further, in those that reported higher pain, there was greater activation of this critically important brain region. The default mode network extends from the posterior cingulate cortex to the medial prefrontal cortex of the brain. These two brain regions continuously feed information back and forth. This network is associated with processing feelings of self and mind wandering. The study provided novel neurobiological information that showed people with higher mindfulness ratings had less activation in the central nodes (posterior cingulate cortex) of the default network and experienced less pain. Those with lower mindfulness ratings had greater activation of this part of the brain and also felt more pain, Zeidan said.

Richard Sackler, the billionaire businessman behind Purdue Pharma, has patented a new drug to help treat opioid addiction (Warning: source may be paywalled; alternative source). The news of the patented form of buprenorphine, a mild opioid that is used to ease withdrawal symptoms, comes as Colorado's attorney general is suing the OxyContin creator for profiting from opioid addictions. Some now believe that Sackler and his family, who owns Purdue Pharma, will be trying to profit from the antidote. The Washington Post reports: The lawsuit claims Purdue Pharma L.P. and Purdue Pharma Inc. deluded doctors and patients in Colorado about the potential for addiction with prescription opioids and continued to push the drugs. And it comes amid news that the company's former chairman and president, Richard Sackler, has patented a new drug to help wean addicts from opioids. "Purdue's habit-forming medications coupled with their reckless marketing have robbed children of their parents, families of their sons and daughters, and destroyed the lives of our friends, neighbors, and co-workers," Colorado Attorney General Cynthia Coffman said Thursday in a statement. "While no amount of money can bring back loved ones, it can compensate for the enormous costs brought about by Purdue's intentional misconduct."

The lawsuit states that Purdue Pharma "downplayed the risk of addiction associated with opioids," "exaggerated the benefits" and "advised health care professionals that they were violating their Hippocratic Oath and failing their patients unless they treated pain symptoms with opioids," according to the statement from the Colorado attorney general's office. But Purdue Pharma "vigorously" denied the accusations Friday in a statement to The Washington Post, saying that although it shares "the state's concern about the opioid crisis," it did not mislead health-care providers about prescription opioids. "The state claims Purdue acted improperly by communicating with prescribers about scientific and medical information that FDA has expressly considered and continues to approve," a spokesman for Purdue Pharma said in the statement. "We believe it is inappropriate for the state to substitute its judgment for the judgment of the regulatory, scientific and medical experts at FDA." The report makes note of the patent's description, which acknowledges the risk of addiction associated with opioids and states that the drug could be used both in drug replacement therapy and pain management.

On Sunday haruchai (Slashdot user #17,472) wrote that a 200-year-old museum in Brazil "is burning to the ground and it's likely the entire collection of some 20 million artifacts will be lost." Now CNET reports: The items in the Museu Nacional in Rio may be gone, but Wikipedia doesn't want them to be forgotten... "Did you take a photo of any of them? Help us preserve the memories of as many as we can and add them to @wikicommons," Wikipedia tweeted Tuesday, with an explanation on how to do so...

"The fire at the National Museum of Brazil has led to the devastating loss of 200 years of memory," Katherine Maher, executive director of the Wikimedia Foundation, said in a statement. "At Wikipedia, our community is hard at work every day curating a living record of our shared heritage," Maher said. "With this effort, we're asking people everywhere to join our global community and help the world recover from this collective tragedy."

The reason Pluto lost its planet status is not valid, according to new research from the University of Central Florida in Orlando. From a report: In 2006, the International Astronomical Union, a global group of astronomy experts, established a definition of a planet that required it to "clear" its orbit, or in other words, be the largest gravitational force in its orbit. Since Neptune's gravity influences its neighboring planet Pluto, and Pluto shares its orbit with frozen gases and objects in the Kuiper belt, that meant Pluto was out of planet status. However, in a new study published online Wednesday in the journal Icarus, UCF planetary scientist Philip Metzger, who is with the university's Florida Space Institute, reported that this standard for classifying planets is not supported in the research literature. Metzger, who is lead author on the study, reviewed scientific literature from the past 200 years and found only one publication -- from 1802 -- that used the clearing-orbit requirement to classify planets, and it was based on since-disproven reasoning. He said moons such as Saturn's Titan and Jupiter's Europa have been routinely called planets by planetary scientists since the time of Galileo.

"The IAU definition would say that the fundamental object of planetary science, the planet, is supposed to be a defined on the basis of a concept that nobody uses in their research," Metzger said. "And it would leave out the second-most complex, interesting planet in our solar system." "We now have a list of well over 100 recent examples of planetary scientists using the word planet in a way that violates the IAU definition, but they are doing it because it's functionally useful," he said. "It's a sloppy definition," Metzger said of the IAU's definition. "They didn't say what they meant by clearing their orbit. If you take that literally, then there are no planets, because no planet clears its orbit."

NASA is challenging people in the United States to come up with an efficient method to convert carbon dioxide into glucose, a simple sugar. The atmosphere of Mars consists predominantly of CO2 (95%), and glucose is a great fuel for microbe-milking "bioreactors" that could manufacture a variety of items for future settlers of the Red Planet, NASA officials said. Space.com reports: The new competition consists of two phases. During Phase 1, applicants submit a detailed description of their CO2-to-glucose conversion system. Interested parties must register by Jan. 24, 2019 and submit their proposals by Feb. 28, 2019. In April, NASA will announce the selection of up to five finalists from this initial crop, each of whom will receive $50,000. Phase 2 will involve the construction and demonstration of a conversion system. Winning this round is worth $750,000, bringing the competition's total purse to $1 million (assuming five finalists are indeed selected from Phase 1). You don't have to win, or even participate in, Phase 1 to compete in Phase 2. The challenge is open to citizens and permanent residents of the United States; foreign nationals can compete if they're part of a U.S.-based team. To register or learn more, go to the CO2 Conversion Challenge website.

The world's largest offshore wind farm has opened off the northwest coast of England. "The wind farm has a capacity of 659 megawatts (MW), enough to power almost 600,000 homes, and overtakes the London Array off England's east cost which has a capacity of 630 MW," reports Reuters. From the report: The Walney Extension (as it is called) is made up of 87 turbines built by Siemens Gamesa and MHI Vestas, and covers 145 square kilometers (55 square miles), which is equivalent to around 20,000 football pitches. The 40 eight-megawatt MHI Vestas turbines being used stand 195 meters (213 yards) tall and are the largest wind turbines in operation globally. Britain is the world's largest offshore wind market, hosting 36 percent of globally installed offshore wind capacity, data from the Global Wind Energy Council showed. Walney Extension was among the first renewable projects to secure a so-called contract for difference (CFD) subsidy from the British government in 2014. The contract guarantees it a minimum price for electricity of 150 pounds ($195) per megawatt hour (MWh) for 15 years. You can view some drone footage of the offshore windfarm via Orsted.

An anonymous reader quotes a report from The Guardian: The gut microbiome is the sum total of all the micro-organisms living in a person's gut, and has been shown to play a huge role in human health. New research has found probiotics -- usually taken as supplements or in foods such as yoghurt, kimchi or kefir -- can hinder a patient's gut microbiome from returning to normal after a course of antibiotics, and that different people respond to probiotics in dramatically different ways. In the first of two papers published in the journal Cell, researchers performed endoscopies and colonoscopies to sample and study the gut microbiomes of people who took antibiotics before and after probiotic consumption. Another group were given samples of their own gut microbiomes collected before consuming antibiotics. The researchers found the microbiomes of those who had taken the probiotics had suffered a "very severe disturbance." "Once the probiotics had colonized the gut, they completely inhibited the return of the indigenous microbiome which was disrupted during antibiotic treatment," said Eran Elinav, an immunologist at the Weizmann Institute of Science in Israel and lead author on the studies.

The scientists also compared the gut microbiomes of the gut intestinal tract of 25 volunteers with that of their stools. They found that stool bacteria only partially correlated with the microbiomes functioning inside their bodies. "So the fact that we all almost exclusively rely on stool in our microbiome research may not be a reliable way of studying gut microbiome health," said Elinav. In the second paper, the researchers examined the colonization and impact of probiotics on 15 people by sampling within their gastrointestinal tract. They divided the individuals into two groups: one were given a preparation made of 11 strains of very commonly used probiotics and the other were given a placebo. Of those who were given probiotics, he said, "We could group the individuals into two distinct groups: one which resisted the colonisation of the probiotics, and one in which the probiotics colonized the gut and modified the composition of the gut microbiome and the genes of the host individual."

A 28-year-old MIT graduate named You Wu spent six years developing a low-cost robot designed to find leaks in pipes early, both to save water and to avoid bigger damage later from bursting water mains. "Called Lighthouse, the robot looks like a badminton birdie," reports Fast Company. "A soft 'skirt' on the device is covered with sensors. As it travels through pipes, propelled by the flowing water, suction tugs at the device when there's a leak, and it records the location, making a map of critical leaks to fix." From the report: MIT doctoral student You Wu spent six years developing the design, building on research that earlier students began under a project sponsored by a university in Saudi Arabia, where most drinking water comes from expensive desalination plants and around a third of it is lost to leaks. It took three years before he had a working prototype. Then Wu got inspiration from an unexpected source: At a party with his partner, he accidentally stepped on her dress. She noticed immediately, unsurprisingly, and Wu realized that he could use a similar skirt-like design on a robot so that the robot could detect subtle tugs from the suction at each leak. Wu graduated from MIT in June, and is now launching the technology through a startup called WatchTower Robotics. The company will soon begin pilots in Australia and in Cambridge, Massachusetts. One challenge now, he says, is creating a guide so water companies can use the device on their own.

A reader shares a report from Space.com: The weird hexagon swirling around Saturn's north pole is much taller than scientists had thought, a new study suggests. Researchers have generally regarded the 20,000-mile-wide (32,000 kilometers) hexagon -- a jet stream composed of air moving at about 200 mph (320 km/h) -- as a lower-atmosphere phenomenon, restricted to the clouds of Saturn's troposphere. But the bizarre structure actually extends about 180 miles (300 km) above those cloud tops, up into the stratosphere, at least during the northern spring and summer, a new study suggests. The hexagon, which surrounds a smaller circular vortex situated at the north pole, has existed for at least 38 years; NASA's Voyager 1 and Voyager 2 spacecraft spotted the sharp-cornered feature when they flew by Saturn in 1980 and 1981, respectively. Scientists started to get much more detailed looks at the hexagon in 2004, when NASA's Cassini spacecraft began orbiting the ringed planet. But Cassini's hexagon observations were pretty much confined to the troposphere for a decade after its arrival; springtime didn't come to Saturn's north until 2009, and low temperatures in the stratosphere continued to compromise measurements by the probe's Composite Infrared Spectrometer (CIRS) instrument for another five years.

The formation of a stratospheric hexagon appears to be tied to the warming brought on by the change of seasons, the research team wrote in the new study. Indeed, Cassini spied a vortex high above the south pole during its early years at Saturn, when that hemisphere was enjoying summer. (Saturn takes 30 Earth years to orbit the sun, so seasons on the ringed planet last about 7.5 years apiece.) But the southern stratospheric vortex wasn't hexagonal. And neither, for that matter, is the vortex that spins around the south pole lower down, in the tropospheric clouds, the researchers said. "This could mean that there's a fundamental asymmetry between Saturn's poles that we're yet to understand, or it could mean that the north polar vortex was still developing in our last observations and kept doing so after Cassini's demise," study lead author Leigh Fletcher, of the University of Leicester in England, said in a statement.

Japan's Ministry of Health, Labor, and Welfare announced for the first time that a man employed at the Fukushima nuclear power plant died of lung cancer linked to radiation exposure. "The man, who was in his 50s, died from lung cancer that was diagnosed in 2016," reports the BBC. "Japan's government had previously agreed that radiation caused illness in four workers but this is the first acknowledged death." From the report: The Fukushima reactor suffered meltdowns after a 9.0 magnitude earthquake and a tsunami in March 2011. Cooling systems were wrecked at the plant on Japan's north-east coast and radioactive material leaked out. The employee who died had worked at atomic power stations since 1980 and was in charge of measuring radiation at the Fukushima No 1 plant shortly after its meltdown. He worked there at least twice after it was damaged, and had worn a face mask and protective suit, Japan's Ministry of Health, Labour and Welfare said. After hearing opinions from a panel of radiologists and other experts, the ministry ruled that the man's family should be paid compensation.

Major Blud writes: Multiple news outlets are reporting that Theranos, the company that promised to revolutionize healthcare with new blood-testing devices, is closing shop. The company "was unable to sell itself and is now looking to pay unsecured creditors its remaining cash of about $5 million in the upcoming months," reports CBS News. The CEO, Elizabeth Holmes, and President/COO Ramesh Balwani recently settled a civil suit with the SEC, which charged them with massive fraud related to them seeking investment based on misleading information regarding the accuracy of their "Edison" diagnostic equipment. According to The Wall Street Journal, investors lost almost $1 billion in the company. At one point, it was valued at almost $10 billion.

Zorro shares a report from Phys.Org: A Japanese team working to develop a "space elevator" will conduct a first trial this month, blasting off a miniature version on satellites to test the technology. The test equipment, produced by researchers at Shizuoka University, will hitch a ride on an H-2B rocket being launched by Japan's space agency from southern island of Tanegashima next week. The test involves a miniature elevator stand-in -- a box just six centimeters (2.4 inches) long, three centimeters wide, and three centimeters high. If all goes well, it will provide proof of concept by moving along a 10-meter cable suspended in space between two mini satellites that will keep it taut. The mini-elevator will travel along the cable from a container in one of the satellites. The movement of the motorized "elevator" box will be monitored with cameras in the satellites.

Last week, NASA discovered a small pressure leak on the International Space Station. U.S. and Russian crew members managed to trace the leak to a 2mm breach in the orbital module of the Soyuz MS-09 vehicle and patch it with epoxy. The drama might have ended there, as it was initially presumed that the breach had been caused by a tiny bit of orbital debris, but Russian news outlets are reporting that the problem was a manufacturing defect. "It remains unclear whether the hole was an accidental error or intentional," reports Ars Technica. "There is evidence that a technician saw the drilling mistake and covered the hole with glue, which prevented the problem from being detected during a vacuum test."

"We are able to narrow down the cause to a technological mistake of a technician. We can see the mark where the drill bit slid along the surface of the hull," Dmitry Rogozin, head of the Russian space agency Roscosmos, told RIA Novosti. "We want to find out the full name of who is at fault -- and we will." From the report: NASA spokesman Dan Huot, based in Houston where the space station program is managed, deferred all comment on the issue to Roscosmos. The spacecraft was manufactured by Energia, a Russian corporation. A former employee of the company who is now a professor at Moscow State University told another Russian publication that these kinds of incidents have occurred before at Energia. "I have conducted investigations of all kinds of spacecraft, and after landing, we discovered a hole drilled completely through the hull of a re-entry module," the former Energia employee, Viktor Minenko, said in Gazeta.RU. "But the technician didn't report the defect to anyone but sealed up the hole with epoxy. We found the person, and after a commotion he was terminated," said Minenko. In this case, the technician used glue instead of epoxy. As the Soyuz hull is made from an aluminum alloy, it could have been properly repaired on Earth by welding, had the technician reported the mistake.
