Particle Accelerator Fits On the Head of a Pin Slashdotby BeauHD on science at January 1, 1970, 1:00 am (cached at January 3, 2020, 11:34 pm)

An anonymous reader quotes a report from TechCrunch: "We want to miniaturize accelerator technology in a way that makes it a more accessible research tool," explained project lead Jelena Vuckovic in a Stanford news release. But this wasn't designed like a traditional particle accelerator like the Large Hadron Collider or one at collaborator SLAC's National Accelerator Laboratory. Instead of engineering it from the bottom up, they fed their requirements to an "inverse design algorithm" that produced the kind of energy pattern they needed from the infrared radiation emitters they wanted to use. That's partly because infrared radiation has a much shorter wavelength than something like microwaves, meaning the mechanisms themselves can be made much smaller -- perhaps too small to adequately design the ordinary way. The algorithm's solution to the team's requirements led to an unusual structure that looks more like a Rorschach test than a particle accelerator. But these blobs and channels are precisely contoured to guide infrared laser light pulse in such a way that they push electrons along the center up to a significant proportion of the speed of light. The resulting "accelerator on a chip" is only a few dozen microns across, making it comfortably smaller than a human hair and more than possible to stack a few on the head of a pin. A couple thousand of them, really. And it will take a couple thousand to get the electrons up to the energy levels needed to be useful -- but don't worry, that's all part of the plan. The chips are fully integrated but can be put in a series easily to create longer assemblies that produce larger powers. These won't be rivaling macro-size accelerators like SLAC's or the Large Hadron Collider, but they could be much more useful for research and clinical applications where planet-destroying power levels aren't required. For instance, a chip-sized electron accelerator might be able to direct radiation into a tumor surgically rather than through the skin. The findings have been published in the journal Science.

Cities Struggle To Boost Ridership With 'Uber for Transit' Schemes Slashdotby msmash on transportation at January 1, 1970, 1:00 am (cached at January 3, 2020, 10:34 pm)

Helsinki, Los Angeles, Shanghai, Singapore, and other metros have been experimenting with on-demand buses -- and not seeing a lot of success. From a report: Since September, commuters using Shanghai's Number 9 bus route have had a new way of catching a ride. Rather than stand at a designated stop, they open a smartphone app and book a ride to wherever they're going. The service, provided by Alibaba, takes those reservations into account and calculates where the bus should go, using the company's artificial intelligence to customize the route. The idea is to boost ridership -- and curb traffic --by making public transit more convenient. Shanghai is just the latest city to give this sort of scheme a try. From Helsinki, Finland, to Sydney, cities around the world have spent the past few years trying to implement AI-fueled, on-demand bus services. Few have succeeded. Earlier this year, Singapore decided against renewing a pilot for on-demand buses. In Germany, microtransit company CleverShuttle -- which bills itself as more of a ride-pooling service than a bus -- pulled out of three of the eight cities it was operating in, citing economic and bureaucratic hurdles. In a pilot project with shared rides company Via, bringing underserved residents to public transit nodes, Los Angeles Metro is spending $14.50 per trip -- twice what it spends on a regular bus trip. On-demand buses have been a thing for decades. Public transit agencies often call them demand-responsive buses, and deploy them to serve users who lack easy access to standard routes because they live especially far away, or may have special needs. Because they reach relatively few people, they're expensive to operate. They're inefficient too, often making riders wait undetermined amounts of time for a ride. So cities must strike a balance between making public transit accessible to the largest number of residents, and meeting their budget goals.

Sony's Robot Dogs Are Helping Japanese People Find Companionship Slashdotby msmash on japan at January 1, 1970, 1:00 am (cached at January 3, 2020, 9:34 pm)

The dogs, known as Aibos, are companion robots made by Sony -- robots that don't necessarily do much apart from providing company and comfort. From a report: Every Aibo -- Japanese for "companion" -- is manufactured identically, besides a choice between silver and white or a brown, black, and white version. They all have rounded snouts that include a camera for facial recognition capability, large, oval eyes to reveal their expressions, and a body that can turn on 22 different axis points to give them a range of motion. The owner decides the gender when they set them up, which determines the pitch of its bark and how it moves. They're cute. They know when you're smiling. And through machine learning and recognizing people with its camera, Aibos also shift their personality over time based on their interactions with people they spend time with. Soon, they become much more than a store-bought toy. Still in the "off" position in the cafe, the Aibos' paws remained outstretched and their heads turned to one side. But one by one, as their owners kneeled down to turn them on from a switch at the scruff of their neck, each came to life. The screen of their doll-like eyes blinked open, they lifted their heads, stretched out their plastic limbs, and leaned back on their hind legs before standing on all fours. Almost like real dogs, they shook their heads as if to ward off sleep after a nap, wagged their tails, and barked.

Is Fry's Electronics in Trouble? Slashdotby msmash on business at January 1, 1970, 1:00 am (cached at January 3, 2020, 9:04 pm)

The tagline "Your best buys are always at Fry's" once blanketed Bay Area airwaves, but that's no longer true of the computer retailer's Palo Alto store. From a report: A temple of electronics known as "ground zero for geek culture," the Portage Avenue Fry's Electronics closed last week after almost 30 years in business. "The Palo Alto store was a fixture for techies everywhere. It's sad they closed," said Abbi Vakil, who works as a hardware engineer in the city. "You will not find an engineer in the Bay Area who hasn't gone to Fry's for some kind of prototype building." Fry's Electronics, a San Jose company that still has dozens of stores from California to Georgia, including seven in the Bay Area, said on Twitter that it had not been able to renew the Palo Alto store's lease. But customers from Sunnyvale to Seattle have been sharing photos and videos of empty shelves on social media for months, raising speculation that the chain may be heading for bankruptcy or shrinking significantly.

Company Shuts Down Because of Ransomware, Leaves 300 Without Jobs Just Before Holida Slashdotby msmash on security at January 1, 1970, 1:00 am (cached at January 3, 2020, 8:34 pm)

An Arkansas-based telemarketing firm sent home more than 300 employees and told them to find new jobs after IT recovery efforts didn't go according to plan following a ransomware incident that took place at the start of October 2019. From a report: Employees of Sherwood-based telemarketing firm The Heritage Company were notified of the decision just days before Christmas, via a letter sent by the company's CEO. Speaking with local media, employees said they had no idea the company had even suffered a ransomware attack, and the layoffs were unexpected, catching many off guard. "Unfortunately, approximately two months ago our Heritage servers were attacked by malicious software that basically 'held us hostage for ransom' and we were forced to pay the crooks to get the 'key' just to get our systems back up and running," wrote Sandra Franecke, the company's CEO, in the letter sent to employees. She goes on to say that data recovery efforts, initially estimated at one week, have not gone according to plan and the company had failed to recover full service by Christmas. Franecke said the company lost "hundreds of thousands of dollars" because of the incident and have been forced to "restructure different areas in the company." As a result of the botched ransomware recovery process, the company's leadership decided to suspend all services, leaving more than 300 employees without jobs.

Chrome To Show Error Codes, Similar To Windows BSOD Screens Slashdotby msmash on chrome at January 1, 1970, 1:00 am (cached at January 3, 2020, 7:34 pm)

Google Chrome will get support for error codes, similar to the ones seen on Windows blue screen of death (BSOD) crash pages. From a report: The idea is to provide Chrome users with a code they can search online and find debugging help for various types of crashes. Work on this new feature started in November last year, and the error codes are already under testing in current Chrome Canary (v81) releases. The error codes will appear on the so-called "sad tab" page, also known as the "Aw, Snap!" page, which Chrome displays when a tab crashes.

A Quarter of the World's Pigs Died Last Year in China Slashdotby msmash on china at January 1, 1970, 1:00 am (cached at January 3, 2020, 7:04 pm)

By the end of August 2019, the entire pig population of China had dropped by about 40 percent. China accounted for more than half of the global pig population in 2018, and the epidemic there alone has killed nearly one-quarter of all the world's pigs. From a report: By late September, the disease had cost economic losses of one trillion yuan (about $141 billion), according to Li Defa, dean of the College of Animal Science and Technology at China Agricultural University in Beijing. Qiu Huaji, a leading Chinese expert on porcine infectious diseases, has said that African swine fever has been no less devastating "than a war" -- in terms of "its effects on the national interest and people's livelihoods and its political, economic and social impact." "We lost hundreds of thousands of yuan," my sister-in-law bemoaned, several tens of thousands of dollars. "Haven't you been compensated by the government for the dead pigs?" I asked. "Only 100 yuan per head," less than $15, she said, "That didn't help."

Climate Change is Intensifying Australia's Fires Slashdotby msmash on australia at January 1, 1970, 1:00 am (cached at January 3, 2020, 6:34 pm)

Tens of thousands of Australians are fleeing their homes as hundreds of fires rage across the continent's southeast coast. And yes, climate change is almost certainly to blame for the extent of the disaster. From a report: With more than a thousand buildings destroyed and 17 deaths since October, it already ranks as one of the worst fire seasons in Australia's history -- and summer there has barely begun. What's driving the fires? Summer wildfires are common in Australia, but climate change is making them worse. Spring rainfall has declined in recent decades, even as temperatures rise, extreme heat events become more common, and droughts turn more severe, according to a 2018 report by Australia's Bureau of Meteorology. Those forces have contributed to a greater number of days with "very high fire dangers," and helped extend the fire season into spring.

Why We Keep Sending Music To Extraterrestrials Slashdotby msmash on music at January 1, 1970, 1:00 am (cached at January 3, 2020, 5:34 pm)

Music is an ideal medium for interstellar communication. From a report: Each summer for the past 25 years, tens of thousands of people have flocked to Barcelona, Spain, to witness Sonar, a three-day festival dedicated to electronic music, art, and design. To celebrate Sonar's 25th anniversary in 2018, the festival partnered with the Catalonia Institute for Space Studies and the nonprofit METI International to send a series of interstellar messages to Luyten's star, a red dwarf about 12 light-years from Earth. Although red dwarfs are the most common stellar objects in our galaxy, Luyten's star is remarkable for hosting GJ237b, the closest potentially habitable planet outside of our own solar system. No one knows for sure whether GJ237b hosts life, intelligent or otherwise, but if ET does call the planet home, Sonar wants to rock its socks off. Over the course of several nights in late 2017 and early 2018, a radar system in Tromso, Norway, blasted a custom message from Sonar toward GJ237b. Like any good correspondence, the message began with a greeting: In this case, the first 33 prime numbers repeated on two alternating radio frequencies functioned as a stand-in for "hello." This was followed by a brief tutorial that the message designers hoped would teach ET to extract the music written by Sonar-affiliated musicians and embedded in the message. [...] The Sonar messages are unique insofar as they are the only interstellar transmissions to use songs designed by musicians specifically for communicating with ET. That the messages include a substantial information content places them firmly in the tradition of messaging extraterrestrial intelligences, or METI, a term coined by the Russian radio astronomer Alexander Zaitsev to differentiate the practice from other modes of interstellar communication. The Search for Extraterrestrial Intelligence, or SETI, is focused on listening for ET signals rather than sending them, and "active SETI" is about creating beacons that lack information but signal to alien intelligences that we exist.

Segway's Newest Self-balancing Vehicle is an Egg-Shaped Wheelchair Slashdotby msmash on transportation at January 1, 1970, 1:00 am (cached at January 3, 2020, 5:04 pm)

Segway's newest self-balancing vehicle won't require you to stand up. From a report: Dubbed the S-Pod, the new egg-shaped two-wheeler from Segway-Ninebot is meant to let people sit while they effortlessly cruise around campuses, theme parks, airports, and maybe even cities -- all of the same places you'd expect to see one of the company's iconic (if still a bit dorky) stand-up vehicles. The S-Pod is powered by basically the same gyroscopic self-balancing technology as a traditional Segway. But unlike a traditional Segway, which is driven by leaning forward, backward, and to the sides, the S-Pod is controlled using a little joystick on the right side of the seat. Segway says its self-balancing technology will always keep the chair level and that the two-wheel setup will allow for quick changes in direction even while stopped. (That said, there are three more small wheels visible on the underside of the chair, presumably for moving the S-Pod while its motors aren't on.)
