Shark sighting prompts Oceanside beach closure


first_img Categories: Local San Diego News FacebookTwitter KUSI Newsroom, Updated: 4:37 PM Posted: November 9, 2018 KUSI Newsroom center_img November 9, 2018 OCEANSIDE (KUSI) – A spate of sightings of a roughly 12-foot shark near Oceanside Municipal Pier Friday afternoon prompted a temporary closure of a two-mile stretch of beach in the area.Fishermen on boats began spotting the sea predator 100 to 500 yards from shore about 12:30 p.m., city lifeguard Sgt. Gregory Trebbe said. Soon, about a half-dozen sightings had been reported.As a public-safety precaution, lifeguards cleared everyone out of the surf a mile to the north and south of the pier, made announcements to beachgoers about the closure and posted signs along the shoreline in the affected area.On the rare occasions when sharks are sighted off the coast of Oceanside, they “are typically just passing through our waters,” posing no active threats to swimmers and surfers, Trebbe noted.“Barring any other reports or incidents, the water will reopen (Saturday) morning,” he said.It was unclear what type of shark was cruising in the area.

Amazons Scout robots Thats no cooler thats your Prime delivery


first_img Tags Amazon’s drones and robots want to take over your deliveries Amazon Scout robots are heading out to deliver packages Amazon Prime Air’s new delivery drone could sneak up on you Inside an Amazon warehouse that ships your supersized purchases More Amazon delivery stories For instance, there’s no way to get packages out of a Scout now without a person coming up to it, pulling open its lid on top and taking out its payload. Scott said one idea could be to have Scouts wait for a while for customers to come home. Also, the Scout has magnetic locks in its lid to keep its top closed while it’s driving and to protect its packages from theft. It’s possible a resident could use the Amazon app in the future to unlock the bot and get her package once she comes home.To train Scouts on how to navigate around Snohomish, Amazon created bicycle trailers that were equipped with the same camera arrays as the robots. Riders would go around in neighborhoods capturing every detail of the sidewalks, streets, gutters and even the weeds.Then, Amazon created virtual worlds that were nearly identical to the streets the Scouts would be driving on and trained the robots over and over again using these digital doubles. That way, when the Scouts were ready to go out into the real world, they would be far more prepared for what they were about to experience.As the Scouts learn more about the world, they can be trained on less information to understand the way around new neighborhoods, allowing Amazon to quickly spread out more Scouts, Scott said.To see where to go, Scouts are equipped with GPS, radar and front- and rear-facing cameras. Scott showed me a video of a Scout in action on the street, slowing rolling along the sidewalk and carefully stopping when a neighborhood cat jumped in front of it.amazon-scout-robot-8Amazon created digital doubles of real neighborhoods to teach the Scouts how to move around. Ben Fox Rubin/CNET The current version is being developed for suburban deliveries, but there’s a possibility future Scout robots will be able to function in a city or rural areas.While the Scouts remain a curiosity now, Scott said the bots were intentionally built to look cute, friendly and most importantly unassuming. Yes, the bots have a bright blue color emblazoned with the Prime logo on either side, as well as bright flashing lights, which are needed for when Scouts cross the street. Plus, when you open a Scout’s lid, it’s painted bright white and orange inside, offering a pleasing contrast to the blue exterior and giving the feel of opening a present. Otherwise, Scouts were built so they would fade into the background and fit seamlessly in a suburban setting.”That’s exactly what we want,” Scott said. “It’s designed for boring.”Originally June 10, 5 a.m. PT.Update, 9:50 a.m. PT: Adds more details about the Scout. 1:32 Plus, Amazon’s leaders have often mentioned that even as the company continues to find new ways to automate tasks, it also continues to hire rapidly as demand from customers grows. Amazon on Friday lost its contract with FedEx Express, a sign of growing friction with its shipping partners as Amazon keeps developing its own delivery infrastructure. If more turmoil like that happens with UPS or the US Postal Service, Amazon will need all the help it can get — from humans and robots — to make sure it delivers its packages on time.Teaching Scout to rollToday, the Scouts are loaded up in vans and brought to neighborhoods where they make their deliveries. To ensure the Scouts are working properly, each robot is assigned an Amazon worker — folks Scott called “ambassadors” — who walks with the bots during their deliveries and removes the packages stowed away in their bellies. The Scout program started with six robots, but Scott didn’t say how many robots are currently in use, or when and where the program will be expanded.The idea is to eventually pair the Scouts with delivery drivers and let the robots operate more on their own, but the details are still being worked out, Scott said. Now playing: Watch this:center_img Share your voice Internet 7 The Scout is already delivering boxes to customers in Snohomish County, Washington. Ben Fox Rubin/CNET Sean Scott is almost poetic when describing his intense interest in sidewalks.”Each sidewalk is like a snowflake,” Scott, who’s soft-spoken with a friendly smile, told me with a bit of excitement in his eyes. “Because the textures are different, the way they’re laid out is different, what we see on the sidewalk is different.”Scott, vice president of the Amazon Scout program, is particularly curious about the drab and overlooked sidewalk because that’s the workspace of his Scout delivery robots. The e-commerce giant in January introduced these machines, which look like blue coolers on six wheels and can autonomously navigate suburban environments to bring packages to customers’ homes. The company is already using them to deliver orders in Snohomish County, Washington, just north of Amazon’s Seattle headquarters.While Amazon has been mostly mum about Scout so far, Scott offered a more in-depth look at the robot during an interview last week at the company’s re:MARS robotics and space conference in Las Vegas. Just across from him in our conference room sat one of these robots, powered off but appearing at-the-ready for its next assignment. amazon-scout-robot-7The Scout uses magnetic locks to keep its lid closed while driving and to protect its packages inside. Ben Fox Rubin/CNET “Customers have really welcomed Amazon Scout,” Scott said. “They find the device really cute.”The bots are another effort by Amazon to add more technology and automation into its delivery infrastructure. It already uses hundreds of thousands of robots in its warehouses to store and move around shelves of products. It’s also been developing drones to get packages to customers in less than 30 minutes. All this work should help Amazon in its costly push to transition its Prime two-day shipping program to one day, a plan it announced in April and is already rolling out.Amazon isn’t alone in its delivery robot work. Google, Workhorse and others are developing delivery drones, while Postmates and the startup Starship are working on sidewalk delivery bots.But as robots have gotten more sophisticated, many people have raised concerns that these machines could replace a lot of human workers, such as autonomous trucks and taxis taking away thousands of professional drivers’ jobs. A Brookings Institution study from January found 25% of US jobs, including food preparation and office administration, are already at high risk of becoming automated.It’s also hard to know how people outside of the Snohomish test area will react to having these camera-filled bots rolling down their streets.”History has shown us that we never know how customers are going to react to anything until they experience it,” said Brendan Witcher, a Forrester analyst. “The other thing history has shown us is some people will bristle and others will be delighted.”It will be up to Amazon, he added, to communicate and be transparent with residents to show them why such robots should be a part of their lives.Scott said Amazon isn’t developing Scout to take away workers’ jobs but instead to improve and grow the company’s delivery infrastructure. “We think it will make delivery drivers more efficient,” helping them deliver more packages, he said.

Photo: AlimuzzamanA humanitarian crisis is unfolding across large areas in South Asia, with more than 16 million people affected by monsoon floods in Nepal, Bangladesh and India, the International Federation of Red Cross and Red Crescent Societies (IFRC) said Friday, reports XinhuaThe agency cited local authorities as saying that flood levels have already reached record highs in Bangladesh, and water of major rivers such as the Jamuna has surpassed warning levels set in 1988, the deadliest floods the country has ever faced, China’s official press agency adds.”This is fast becoming one of the most serious humanitarian crises this region has seen in many years and urgent action is needed to meet the growing needs of millions of people affected by these devastating floods,” the IFRC said in a statement Friday, citing its staff for Asia Pacific region.According to the statement, more than one third of Bangladesh and Nepal have been flooded, and the humanitarian crisis could get worse in the days and weeks ahead.In Nepal, the IFRC said, many areas remain cut off after recent destructive floods and landslides, and many villages and communities are stranded without food, water or electricity.”This tragic flooding in Nepal has claimed at least 128 lives and 33 people are still missing,” Dev Ratna Dhakhwa, secretary general of the Nepal Red Cross Society, was cited as saying.In Bangladesh, the IFRC said, over 3.9 million people have been affected by the rising flood waters, and floods are likely to get much worse as swollen rivers from India pour into the low-lying and densely populated areas in the northern and central parts of the country, says Xinhua news agency.In India, over 11 million people are reportedly affected by floods in four states across the north of the country. What’s more, India’s meteorological department is forecasting more heavy rains for the region in the coming days.last_img read more

Lab experiments offer credence to theory that subducted crust exists at the


first_img © 2019 Science X Network Explore further A team of researchers affiliated with several institutions in Japan has found evidence that offers credence to a theory that subducted crust exists at the base of Earth’s upper mantle. In their paper published in the journal Nature, the group describes experiments they conducted in their lab involving pressurizing material believed to exist in the mantle, and what they found. Johannes Buchen, with the California Institute of Technology, has written a News & Views piece on the work in the same journal issue.

Sound velocity of CaSiO3 perovskite suggests the presence of basaltic crust in the Earth’s lower mantle, Nature (2019). DOI: 10.1038/s41586-018-0816-5center_img Journal information: Nature Prior research has suggested that as tectonic plates shift around, some of the material on the surface is pushed below. Prior research has also suggested that such material would likely sink deep into the mantle because it is denser than the pyrolite that is believed to make up most of the mantle. Researchers theorize that that the subducted material would likely settle in the bottom of the transition zone between the upper and lower mantle—but to date, there has been little evidence backing up this theory. The primary test has been analyzing seismic waves traveling through such material, but these readings have two possible explanations—the first is that differences in the speed of waves traveling through material in the area is due to dehydration melting. The other is that it is surface material that has drifted down into the mantle. In this new effort, the researchers report that they believe they have found evidence that supports the latter theory.The researchers started by noting that the crust beneath the oceans is made mainly of basalt. They also noted that prior research showed that when basalt makes its way into the crust, a mineral called calcium silicate perovskite (CaSiO3) is created. Thus, if crust material made its way to the transition zone, it would be in the form of CaSiO3. But CaSiO3 exists in two configurations depending on its environment—at high temperature and high pressure, it has cubic symmetry. At lower temperatures and pressure, such as on the surface, it has tetragonal symmetry. That meant the team had to subject a sample of the crystal to pressure and temperatures approximately equal to that found in the mantle to test it. Once they succeeded, they sent ultrasonic waves through it to see if they matched what theory had suggested. They found that the cubic form of CaSiO3 did, indeed, slow the waves in approximately the same way as they do when passing through parts of the mantle, suggesting that the material there is very nearly the same. And that suggests the material is, indeed, subducted crust. Subducting slabs of the Earth’s crust may generate unusual features spotted near the core This document is subject to copyright.
