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.

The Verge Goes Hands-On With the 'Wildly Ambitious' RED Hydrogen One Smartphone (theverge.com) 53
RED is planning on starting with a module that is essentially a huge camera sensor -- the company is not ready to give exact details, but the plan is definitely more towards DSLR size than smartphone size. Then, according to CEO Jim Jannard, the company wants any traditional big camera lens to be attached to it. Answering a fan question, he joked that support for lenses will be "pretty limited," working "just" with Fuji, Canon, Nikon, Leica, and more. [...] The processor inside will be a slightly-out-of-date Qualcomm Snapdragon 835, but it seemed fast enough in the few demos I was able to try. Honestly, though, if you're looking to get this thing just as a phone, you're probably making your decision based on the wrong metrics. It's probably going to be a perfectly capable phone, but at this price (starting at $1,195) what you're buying into is the module ecosystem.

No Fossil Fuel-Based Generation Was Added To US Grid Last Month (arstechnica.com) 123
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."

Ask Slashdot: Could Asimov's Three Laws of Robotics Ensure Safe AI? (wikipedia.org) 235
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..."
But what are your own thoughts? Do you think Asimov's Three Laws of Robotics could ensure safe AI?

Rebuilding the PDP-11/70 with a Raspberry Pi (wixsite.com) 96
Long-time Slashdot reader cptnapalm writes: Oscar Vermeulen's PiDP-11 front panel, modeling a PDP-11/70 in all its colorful glory, has been released to beta testers. This is Mr. Vermeulen's second DEC front panel; his PiDP-8 was released a few years ago. The PiDP-11 panel is designed to work with a Raspberry Pi running simh or, possibly, a FPGA implementation of the Digital Equipment Corporation PDP-11... In addition to the front panel with its switches and blinkenlights, also included is a prototyping area for the possibility of adding new hardware...
UNIX and later BSD were developed on the PDP-11, including both the creation of the C language, the pipe concept and the text editor vi.

In Virtual Reality, How Much Body Do You Need? (nytimes.com) 34
Using an Oculus Rift virtual reality headset and a motion sensor, Dr. Kitazaki's team performed a series of experiments in which volunteers watched disembodied hands and feet move two meters in front of them in a virtual room. In one experiment, when the hands and feet mirrored the participants' own movements, people reported feeling as if the space between the appendages were their own bodies. In another experiment, the scientists induced illusory ownership of an invisible body, then blacked out the headset display, effectively blindfolding the subjects. The researchers then pulled them a random distance back and asked them to return to their original position, still virtually blindfolded. Consistently, the participants overshot their starting point, suggesting that their sense of body had drifted or "projected" forward, toward the transparent avatar.

With Steam Link App, Your Smartphone Can Be An Imperfect Gaming Monitor (arstechnica.com) 47
Switching over to a 5GHz tri-band router (The Netgear Nighthawk X6, to be precise), the same network test reported a "fantastic" connection that "look[s] like it will work well with Steam." On this router, remotely played games ran incredibly smoothly at the iPad's full 1080p resolution, with total round-trip display latency ranging anywhere from 50 to 150ms, according to Steam Link's reports (and one-way "input lag" of less than 1ms). At that level of delay, playing felt practically indistinguishable from playing directly on the computer, with no noticeable gameplay impact even on quick-response titles like Cuphead.

Microsoft Announces Xbox Adaptive Controller For Players With Disabilities (theverge.com) 19
The focus is on connectivity and customizability, with players able to build a setup that works for their capabilities and needs. It won't be an all-in-one solution for many games, but through the use of peripherals and the Xbox's system-level button remapping, the possibilities could be endless. The Xbox Adaptive Controller will cost $99.99 and goes on sale later this year.

The Boston Restaurant Where Robots Have Replaced the Chefs (washingtonpost.com) 110
"The ingredients are portioned into the correct sizes and then delivered to a robotic wok, where they are tumbled at 450 degrees Fahrenheit. The ingredients are cooked and seared. And once the process is complete, the woks tilt downward and put food into a bowl. And then they're ready to be garnished and served." Spyce bills itself as "the world's first restaurant featuring a robotic kitchen that cooks complex meals," a distinction that appears to reference burger-flipping robots like "Flippy," who plied his trade in a California fast food kitchen before being temporary suspended -- because he wasn't working fast enough.

Microsoft To Launch a Line of Lower-Cost Surface Tablets With 10-inch Displays By Second Half of 2018, Report Says (bloomberg.com) 75
The new tablets will feature 10-inch screens -- around the same size as a standard iPad, but smaller than the 12-inch screens used on the Surface Pro laptop line. The new Surfaces, priced about $400, will have rounded edges like an iPad, differing from the squared off corners of current models. They'll also include USB-C connectivity, a first for Surface tablets, a new charging and syncing standard being used by some of the latest smartphones. The tablets are expected to be about 20 percent lighter than the high-end models, but will have around four hours fewer of battery life. (The current Surface Pro can last 13.5 hours on a single charge.)

Tesla Unveils New Large Powerpack Project For Grid Balancing In Europe (electrek.co) 99
Restore UK Vice President Louis Burford told The Energyst that they are bundling their assets like batteries as a "synthetic pool": "By creating synthetic pools or portfolios, you reduce the technical requirements on individual assets that otherwise would not be able to participate [in certain balancing services]. By doing so you create value where it does not ordinarily exist. That is only achievable through synthetic portfolios." For those interested, Tesla has released promo video on YouTube about the project.

Suspect Identified In CIA 'Vault 7' Leak (nytimes.com) 106
F.B.I. agents searched the Manhattan apartment of the suspect, Joshua A. Schulte, one week after WikiLeaks released the first of the C.I.A. documents in March last year, and then stopped him from flying to Mexico on vacation, taking his passport, according to court records and family members. The search warrant application said Mr. Schulte was suspected of "distribution of national defense information," and agents told the court they had retrieved "N.S.A. and C.I.A. paperwork" in addition to a computer, tablet, phone and other electronics. But instead of charging Mr. Schulte in the breach, referred to as the Vault 7 leak, prosecutors charged him last August with possessing child pornography, saying agents had found the material on a server he created as a business in 2009 while he was a student at the University of Texas.
