An anonymous reader quotes a report from Scientific American: UCLA neuroscientists reported Monday that they have transferred a memory from one animal to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain. The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to one day restore lost memories and, if correct, could shake up the field of memory and learning. The researchers extracted RNA from the nervous systems of snails that had been shocked and injected the material into unshocked snails. RNA's primary role is to serve as a messenger inside cells, carrying protein-making instructions from its cousin DNA. But when this RNA was injected, these naive snails withdrew their siphons for extended periods of time after a soft touch. Control snails that received injections of RNA from snails that had not received shocks did not withdraw their siphons for as long.
Glanzman's group went further, showing that Aplysia sensory neurons in Petri dishes were more excitable, as they tend to be after being shocked, if they were exposed to RNA from shocked snails. Exposure to RNA from snails that had never been shocked did not cause the cells to become more excitable. The results, said Glanzman, suggest that memories may be stored within the nucleus of neurons, where RNA is synthesized and can act on DNA to turn genes on and off. He said he thought memory storage involved these epigenetic changes -- changes in the activity of genes and not in the DNA sequences that make up those genes -- that are mediated by RNA. This view challenges the widely held notion that memories are stored by enhancing synaptic connections between neurons. Rather, Glanzman sees synaptic changes that occur during memory formation as flowing from the information that the RNA is carrying. The study has been published in the journal eNeuro.Read Replies (0)

Rei writes: Yesterday evening, Elon Musk announced the pricing and specs for two of the Model 3's most in-demand options -- dual motor and performance versions. The base dual motor configuration adds an AC induction front motor to the current partial-PM reluctance rear motor for $5,000; in addition to AWD and allowing the car to drive with either motor out, this cuts the 0 to 60 mph acceleration time from 5.1 seconds to 4.5 seconds. The performance package is available as a bundle, including the long-range pack, premium interior, 20" wheels, carbon fiber spoiler, and a new black-and-white interior. The vehicle will cost $78,000; 0 to 60 mph times are further cut to 3.5 seconds and the top speed increases from 140 mph to 155 mph. While these options have consistently polled as the most in-demand options not yet available, several still remain and are variously due late this year/early next year: cream interior, non-PUP, tow hitch, SR battery, and air suspension. EU-spec and China-spec are also due early next year. Production is currently over 3,500 per week, rumored to be 4,300 per week, and will be undergoing a shutdown from May 26-31 to raise production to the Q2 target of 5000-6000.Read Replies (0)

An anonymous reader quotes a report from ZDNet: At least one server used by an app for parents to monitor their teenagers' phone activity has leaked tens of thousands of accounts of both parents and children. The mobile app, TeenSafe, bills itself as a "secure" monitoring app for iOS and Android, which lets parents view their child's text messages and location, monitor who they're calling and when, access their web browsing history, and find out which apps they have installed. But the Los Angeles, Calif.-based company left its servers, hosted on Amazon's cloud, unprotected and accessible by anyone without a password. "We have taken action to close one of our servers to the public and begun alerting customers that could potentially be impacted," said a TeenSafe spokesperson told ZDNet on Sunday. The database stores the parent's email address associated with their associated child's Apple ID email address. It also includes the child's device name -- which is often just their name -- and their device's unique identifier. The data contains the plaintext passwords for the child's Apple ID. Because the app requires that two-factor authentication is turned off, a malicious actor viewing this data only needs to use the credentials to break into the child's account to access their personal content data.Read Replies (0)

A scientific paper, originally published in March, from peer-reviewed journal Progress in Biophysics and Molecular Biology has found its way in this week's news-cycle. The paper, which is co-written by 33 authors including molecular immunologist Edward Steele and astrobiologist Chandra Wickramasinghe, suggests that octopuses could be aliens, adding legitimacy to a belief, which otherwise has been debunked several times in the recent years. An excerpt from the paper, which makes the bold claim: The genetic divergence of Octopus from its ancestral coleoid sub-class is very great ... Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch color and shape are just a few of the striking features that appear suddenly on the evolutionary scene. [...] It is plausible then to suggest they [octopuses] seem to be borrowed from a far distant 'future' in terms of terrestrial evolution, or more realistically from the cosmos at large."Ephrat Livni of Quartz questions the basis of the finding: To make matters even more strange, the paper posits that octopuses could have arrived on Earth in "an already coherent group of functioning genes within (say) cryopreserved and matrix protected fertilized octopus eggs." And these eggs might have "arrived in icy bolides several hundred million years ago." The authors admit, though, that "such an extraterrestrial origin...of course, runs counter to the prevailing dominant paradigm." Indeed, few in the scientific community would agree that octopuses come from outer space. But the paper is not just about the provenance of cephalopods. Its proposal that octopuses could be extraterrestrials is just a small part of a much more extensive discussion of a theory called "panspermia," which has its roots in the ideas of ancient Greece. Newsweek spoke with Avi Loeb, the Frank B. Baird Jr. Professor of Science at Harvard University, who told the publication that the paper has raised "an interesting but controversial possibility." However, he added, that it offers no "indisputable proof" that the Cambrian explosion is the result of panspermia. Further reading: Cosmos magazine has outlined some flaws in the assumptions that the authors made in the paper. It has also looked into the background of some of the authors. The magazine also points out that though the paper has made bold claims, it has yet to find support or corroboration from the scientific community. News outlet Live Science has also questioned the findings.Read Replies (0)

MSNBC recently published a video of Bill Gates telling his staff at the Gates Foundation that he had two meetings with Donald Trump since the president was elected. In the video, Gates says Trump doesn't know the difference between two sexually transmitted diseases -- human papillomavirus (HPV) and human immunodeficiency virus (HIV) -- and that it was "scary" how much Trump knew about Gates' daughter's appearance. Gates also said he urged Trump to support innovation and technology during those meetings. CNN reports: Taking audience questions about his interactions with Trump at a Bill & Melinda Gates Foundation meeting, the former Microsoft honcho said he first met Trump in December 2016. He told the audience that Trump had previously come across his daughter, Jennifer, at a horse show in Florida. "And then about 20 minutes later he flew in on a helicopter to the same place," Gates said, according to video of the event broadcast by MSNBC late Thursday. "So clearly he had been driven away but he wanted to make a grand entrance in a helicopter. "Anyway, so when I first talked to him, it was actually kind of scary how much he knew about my daughter's appearance. Melinda (Gates' wife) didn't like that too well."
Gates also said he discussed science with Trump on two separate occasions, where he says the President questioned him on the difference between HIV and HPV. "In both of those two meetings, he asked me if vaccines weren't a bad thing because he was considering a commission to look into ill-effects of vaccines and somebody -- I think it was Robert Kennedy Jr. -- was advising him that vaccines were causing bad things. And I said no, that's a dead end, that would be a bad thing, don't do that. "Both times he wanted to know if there was a difference between HIV and HPV so I was able to explain that those are rarely confused with each other," Gates said.Read Replies (0)

It's been almost a year since RED, a company known for its high-end $10,000+ cameras, teased a smartphone called the RED Hydrogen One. Several months have passed since the phone was announced and we still don't know much about it, aside from it having a very industrial design and "Hydrogen holographic display." Earlier this week, AT&T and Verizon confirmed that they'll launch the device later this year. Now, The Verge's Dieter Bohn has shared his hands-on impressions with the device, which he claims to be "one of the most ambitious smartphones in years from a company not named Apple, Google, or Samsung." Here's an excerpt from the report: The company better known for high-end 4K cameras with names like "Weapon" and "Epic-w" isn't entering the smartphone game simply to sell you a better Android phone. No, this phone is meant to be one piece of a modular system of cameras and other media creation equipment -- the company claims it will be "the foundation of a future multi-dimensional media system." To that end, it has a big set of pogo-pins on the back to connect it to RED's other cameras also to allow users to attach (forthcoming) modules to it, including lens mounts. If it were just a modular smartphone, we'd be talking about whether we really expected the company to produce enough modules to support it.

An anonymous reader quotes a report from Reuters: Beijing's unslakeable thirst for the latest technology has spurred a proliferation of "accelerators" in Silicon Valley that aim to identify promising startups and bring them to China. The surge in the number of China-focused accelerators -- which support, mentor and invest in early-stage startups -- is part of a larger wave of Chinese investment in Silicon Valley. At least 11 such programs have been created in the San Francisco Bay Area since 2013, according to the tech-sector data firm Crunchbase. Some work directly with Chinese governments, which provide funding. Reuters interviews with the incubators showed that many were focused on bringing U.S. startups to China. For U.S. government officials wary of China's growing high-tech clout, the accelerator boom reaffirms fears that U.S. technological know-how is being transferred to China through investments, joint ventures or licensing agreements. "Our intellectual property is the future of our economy and our security," Senator Mark Warner, the Democratic vice-chairman of the U.S. Senate Intelligence Committee, said in a statement to Reuters about Chinese accelerators. "China's government has clearly prioritized acquiring as much of that intellectual property as possible. Their ongoing efforts, legal or illegal, pose a risk that we have to look at very seriously."Read Replies (0)

On July 1st, the country of Estonia will create the largest 24/7 free public transit zone in the world, making it feasibly possible to travel by bus from one end of the 1.3 million-strong Baltic nation to the other without paying a cent. CityLab reports: Estonia is already a world leader in free public transit: In 2013, all public transit in its capital, Tallinn, became free to local residents (but not tourists or other visitors, even those from other parts of the country). The new national free-ride scheme with extend this model even further, making all state-run bus travel in rural municipalities free and extending cost-free transit out from the capital into other regions. The plan will not, however, extend Tallinn's existing free public transit policies to other Estonian cities, and it also won't make riding Tallinn transit free to visitors (at least, not initially). So while most of the country's land area and population -- which is overwhelmingly concentrated around Tallinn -- should get fare-free daily lives, it's not precisely the case that no Estonian will ever buy a bus ticket in their own country again.

The popular Gboard keyboard app for iOS and Android devices has a fundamental flaw. According Reddit user SurroundedByMachines, the red underline has stopped appearing for incorrectly spelled words since November of last year -- and it doesn't appear to be limited to any one device. Issues with the spell checker have been reported on multiple devices across Android and iOS. A simple Google search brings up several different threads where people have reported issues with the feature.
What's more is that nobody at Google seems to get the memo. The Reddit user who first brought this to our attention filed several bug reports, left a review, and joined the beta channel to leave feedback there, yet no response was given.
"Many people have been having the issue, and it's even been escalated to the community manager," writes SurroundedByMachines. Since the app has over 500 million downloads on the Play Store alone, this issue could be frustrating a lot of users, especially those who use their phones to send work emails or write documents. Have you noticed Gboard's broken spell checker on your device? If so, you may want to look into another third-party keyboard, such as SwiftKey or Cheetah Keyboard.Read Replies (0)

An anonymous reader quotes a report from Ars Technica: In the U.S., two types of electricity generation are on the rise: natural gas and renewables. If one of those is set to make a bigger mark than the other this year, it's natural gas: in 2018, natural gas-burning capacity is expected to outpace renewable capacity for the first time in five years, according to data from the Energy Information Agency. Although natural gas additions are expected to overtake renewable energy additions in 2018, forecasts for renewable energy additions to the grid roughly match what we saw in 2017. Natural gas is overtaking renewables not because renewable energy adoption is slowing, but more because natural gas facilities are seeing a considerable boom.
In fact, barring any changes in the EIA numbers, natural gas, wind, and solar generation are the only electricity generation sources that will be added to the U.S. grid in any consequential manner in 2018. Battery, hydroelectric, and biomass facilities make up the small percentage of "other" sources that are expected to come online this year. Renewable energy also started off the year strong. According to the EIA, "in February 2018, for the first time in decades, all of the new generating capacity coming online within a month were non-fossil-fueled. Of the 475 MW of capacity that came online in February, 81 percent was wind, 16 percent was solar photovoltaic, and the remaining 3 percent was hydro and biomass."Read Replies (0)

Long-time Slashdot reader Zorro quotes Nextgov:
The Defense Department is funding a project that officials say could revolutionize the way companies, federal agencies and the military itself verify that people are who they say they are and it could be available in most commercial smartphones within two years. The technology, which will be embedded in smartphones' hardware, will analyze a variety of identifiers that are unique to an individual, such as the hand pressure and wrist tension when the person holds a smartphone and the person's peculiar gait while walking, said Steve Wallace, technical director at the Defense Information Systems Agency.
Organizations that use the tool can combine those identifiers to give the phone holder a "risk score," Wallace said. If the risk score is low enough, the organization can presume the person is who she says she is and grant her access to sensitive files on the phone or on a connected computer or grant her access to a secure facility. If the score's too high, she'll be locked out... Another identifier that will likely be built into the chips is a GPS tracker that will store encrypted information about a person's movements, Wallace said. The verification tool would analyze historical information about a person's locations and major, recent anomalies would raise the person's risk score.
A technical director at the agency "declined to say which smartphone and chipmakers planned to participate in the project, but said the capability will be available 'in the vast majority of mobile devices.'"Read Replies (0)

The CBC reports:
When the siren-like sounds from an Amber Alert rang out on cellular phones across Ontario on Monday, it sparked a bit of a backlash against Canada's new mobile emergency alert system. The Ontario Provincial Police had issued the alert for a missing eight-year-old boy in the Thunder Bay region. (The boy has since been found safe)... On social media, people startled by the alerts complained about the number of alerts they received and that they had received separate alerts in English and French... Meanwhile, others who were located far from the incident felt that receiving the alert was pointless. "I've received two Amber Alerts today for Thunder Bay, which is 15 hours away from Toronto by car," tweeted Molly Sauter. "Congrats, you have trained me to ignore Emergency Alerts...."
The CRTC ordered wireless providers to implement the system to distribute warnings of imminent safety threats such as tornadoes, floods, Amber Alerts or terrorist threats. Telecom companies had favoured an opt-out option or the ability to disable the alarm for some types of alerts. But this was rejected by the broadcasting and telecommunications regulator. Individuals concerned about receiving these alerts are left with a couple of options: they can turn off their phone -- it will not be forced on by the alert -- or mute their phone so they won't hear it.
Long-time Slashdot reader knorthern knight complains that the first two alerts-- one in English, followed by one in French -- were then followed by a third (bi-lingual) alert advising recipients to ignore the previous two alerts, since the missing child had been found.Read Replies (0)

An anonymous reader writes:
Tech blogger John Gruber appears to have successfully identified one of the restaurants mentioned in a post on Google's AI blog that bragged about "a meal booked through a call from Duplex." Mashable then asked a restaurant employee there if Google had let him know in advance that they'd be receiving a call from their non-human personal assistant AI. "No, of course no," he replied. And "When I asked him to confirm one more time that Duplex had called...he appeared to get nervous and immediately said he needed to go. He then hung up the phone."
John Gruber now asks: "How many real-world businesses has Google Duplex been calling and not identifying itself as an AI, leaving people to think they're actually speaking to another human...? And if 'Victor' is correct that Hong's Gourmet had no advance knowledge of the call, Google may have violated California law by recording the call." Friday he added that "This wouldn't send anyone to prison, but it would be a bit of an embarrassment, and would reinforce the notion that Google has a cavalier stance on privacy (and adhering to privacy laws)."
The Mercury News also reports that legal experts "raised questions about how Google's possible need to record Duplex's phone conversations to improve its artificial intelligence may come in conflict with California's strict two-party consent law, where all parties involved in a private phone conversation need to agree to being recorded."
For another perspective, Gizmodo's senior reviews editor reminds readers that "pretty much all tech demos are fake as hell." Speaking of Google's controversial Duplex demo, she writes that "If it didn't happen, if it is all a lie, well then I'll be totally disappointed. But I can't say I'll be surprised."Read Replies (0)

The Washington Post notes the billions of license plate scans coming from modern repo men "able to use big data to find targets" -- including one who drives "a beat-up Ford Crown Victoria sedan."
It had four small cameras mounted on the trunk and a laptop bolted to the dash. The high-speed cameras captured every passing license plate. The computer contained a growing list of hundreds of thousands of vehicles with seriously late loans. The system could spot a repossession in an instant. Even better, it could keep tabs on a car long before the loan went bad... Repo agents are the unpopular foot soldiers in the nation's $1.2 trillion auto loan market... they are the closest most people come to a faceless, sophisticated financial system that can upend their lives...
Derek Lewis works for Relentless Recovery, the largest repo company in Ohio and its busiest collector of license plate scans. Last year, the company repossessed more than 25,500 vehicles -- including tractor trailers and riding lawn mowers. Business has more than doubled since 2014, the company said. Even with the rising deployment of remote engine cutoffs and GPS locators in cars, repo agencies remain dominant. Relentless scanned 28 million license plates last year, a demonstration of its recent, heavy push into technology. It now has more than 40 camera-equipped vehicles, mostly spotter cars. Agents are finding repos they never would have a few years ago. The company's goal is to capture every plate in Ohio and use that information to reveal patterns... "It's kind of scary, but it's amazing," said Alana Ferrante, chief executive of Relentless.

"If science-fiction has already explored the issue of humans and intelligent robots or AI co-existing in various ways, isn't there a lot to be learned...?" asks Slashdot reader OpenSourceAllTheWay.
There is much screaming lately about possible dangers to humanity posed by AI that gets smarter and smarter and more capable and might -- at some point -- even decide that humans are a problem for the planet. But some seminal science-fiction works mulled such scenarios long before even 8-bit home computers entered our lives.
The original submission cites Isaac Asimov's Three Laws of Robotics from the 1950 collection I, Robot.
A robot may not injure a human being or, through inaction, allow a human being to come to harm.A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
The original submission asks, "If you programmed an AI not to be able to break an updated and extended version of Asimov's Laws, would you not have reasonable confidence that the AI won't go crazy and start harming humans? Or are Asimov and other writers who mulled these questions 'So 20th Century' that AI builders won't even consider learning from their work?"
Wolfrider (Slashdot reader #856) is an Asimov fan, and writes that "Eventually I came across an article with the critical observation that the '3 Laws' were used by Asimov to drive plot points and were not to be seriously considered as 'basics' for robot behavior. Additionally, Giskard comes up with a '4th Law' on his own and (as he is dying) passes it on to R. Daneel Olivaw."
And Slashdot reader Rick Schumann argues that Asimov's Three Laws of Robotics "would only ever apply to a synthetic mind that can actually think; nothing currently being produced is capable of any such thing, therefore it does not apply..."

The investigative news "I-Team" of a local TV station in Washington D.C. drove around with "a leading mobile security expert" -- and discovered dozens of StingRay devices mimicking cellphone towers to track phone and intercept calls in Maryland, Northern Virginia, and Washington, D.C. An anonymous reader quotes their report:
The I-Team found them in high-profile areas like outside the Trump International Hotel on Pennsylvania Avenue and while driving across the 14th Street bridge into Crystal City... The I-Team's test phones detected 40 potential locations where the spy devices could be operating, while driving around for just a few hours. "I suppose if you spent more time you'd find even more," said D.C. Councilwoman Mary Cheh. "I have bad news for the public: Our privacy isn't what it once was..."
The good news is about half the devices the I-Team found were likely law enforcement investigating crimes or our government using the devices defensively to identify certain cellphone numbers as they approach important locations, said Aaron Turner, a leading mobile security expert... The I-Team got picked up [by StingRay devices] twice off of International Drive, right near the Chinese and Israeli embassies, then got another two hits along Massachusetts Avenue near Romania and Turkey... The phones appeared to remain connected to a fake tower the longest, right near the Russian Embassy.
StringRay devices are also being used in at least 25 states by police departments, according to the ACLU. The devices were authorized by the FCC back in 2011 for "federal, state, local public safety and law enforcement officials only" (and requiring coordination with the FBI).
