Submission + - 'Life or Death:' AI-Generated Mushroom Foraging Books Are All Over Amazon (404media.co)

Submitted by samleecole
samleecole writes: A genre of AI-generated books on Amazon is scaring foragers and mycologists: cookbooks and identification guides for mushrooms aimed at beginners.

Amazon has an AI-generated books problem that’s been documented by journalists for months. Many of these books are obviously gibberish designed to make money. But experts say that AI-generated foraging books, specifically, could actually kill people if they eat the wrong mushroom because a guidebook written by an AI prompt said it was safe.

The New York Mycological Society (NYMS) warned on social media that the proliferation of AI-generated foraging books could “mean life or death.”

A quick scan of Amazon’s mushroom and foraging books revealed a bunch of books likely written by ChatGPT, but are sold without any indication that they’re AI-generated and are marketed as having been written by a human when they’re probably not. 404 Media used GPT text detectors and AI image detection tools on some of the suspicious books, and found that they were very likely made with AI, with authors who may not even exist.

Submission + - Paralyzed Woman Able To 'Speak' Through Digital Avatar In World First (theguardian.com)

Submitted by Anonymous Coward
An anonymous reader writes: A severely paralysed woman has been able to speak through an avatar using technology that translated her brain signals into speech and facial expressions. The latest technology uses tiny electrodes implanted on the surface of the brain to detect electrical activity in the part of the brain that controls speech and face movements. These signals are translated directly into a digital avatar’s speech and facial expressions including smiling, frowning or surprise. The patient, a 47-year-old woman, Ann, has been severely paralyzed since suffering a brainstem stroke more than 18 years ago. She cannot speak or type and normally communicates using movement-tracking technology that allows her to slowly select letters at up to 14 words a minute. She hopes the avatar technology could enable her to work as a counsellor in future.

The team implanted a paper-thin rectangle of 253 electrodes on to the surface of Ann’s brain over a region critical for speech. The electrodes intercepted the brain signals that, if not for the stroke, would have controlled muscles in her tongue, jaw, larynx and face. After implantation, Ann worked with the team to train the system’s AI algorithm to detect her unique brain signals for various speech sounds by repeating different phrases repeatedly. The computer learned 39 distinctive sounds and a Chat GPT-style language model was used to translate the signals into intelligible sentences. This was then used to control an avatar with a voice personalized to sound like Ann’s voice before the injury, based on a recording of her speaking at her wedding.

The technology was not perfect, decoding words incorrectly 28% of the time in a test run involving more than 500 phrases, and it generated brain-to-text at a rate of 78 words a minute, compared with the 110-150 words typically spoken in natural conversation. However, scientists said the latest advances in accuracy, speed and sophistication suggest the technology is now at a point of being practically useful for patients. A crucial next step is to create a wireless version of the BCI that could be implanted beneath the skull.

Submission + - Octopuses Can Rewire Their 'Brains' By Editing Their Own RNA On the Fly (sciencealert.com)

Submitted by Anonymous Coward
An anonymous reader writes: Octopuses have found an incredible way to protect the more delicate features of their nervous system against radically changing temperatures. When conditions fluctuate, they can rapidly recode key proteins in their nerve cells, ensuring critical neurological activities remain functional when temperatures drop dramatically. How do they do it? By deploying a rare superpower – editing their RNA on the fly, an ability found in some species of octopuses, squids and cuttlefish. It's an unusual strategy, but it appears to be an effective one, and scientists believe that it may be widely adopted throughout the world of cephalopods. [...]

Their subjects were California two-spot octopuses (Octopus bimaculoides), whose entire genome was first sequenced in 2005, making it a useful animal for understanding genetic changes. The researchers acclimated these octopuses to warm water at 22 degrees Celsius (71.6 Fahrenheit) or much chillier water at 13 degrees Celsius (55.4 Fahrenheit), then compared their genetic information against the database genome. They specifically looked at over 60,000 known editing sites, and what they found was astonishing. "Temperature-sensitive editing occurred at about one third of our sites – over 20,000 individual places – so this is not something that happens here or there; this is a global phenomenon," says physicist Eli Eisenberg of Tel-Aviv University, co-senior author of the paper. "But that being said, it does not happen equally: proteins that are edited tend to be neural proteins, and almost all sites that are temperature sensitive are more highly edited in the cold."

So the editing seemed to be in response to acclimating to cold, rather than warm water, affecting neural proteins that, specifically, are sensitive to cold temperatures. And tests of structural proteins critical for the function of the octopus nervous system – kinesin and synaptotagmin – found that the changes wrought would have an impact on their function. It was possible that what the team observed was the result of being in a lab, so they caught wild California two-spot octopuses and Verrill's two-spot octopuses (Octopus bimaculatus) in Summer and Winter and checked their genomes, too. These octopuses had similar patterns of RNA editing that suggested they were optimizing their function for the current temperature conditions.

The team also tested to see how quickly the changes take place. They tweaked the temperature of an octopus's tank from 14 degrees Celsius to 24 degrees Celsius or vice versa, tuning the temperature up or down by 0.5 degrees increments over the course of 20 hours. They tested the extent of RNA editing in each octopus just before starting the temperature change, just after, and four days later. It happens very quickly, the researchers found. "We had no real idea how quickly this can occur: whether it takes weeks or hours," explains [marine biologist Matthew Birk of the Marine Biological Laboratory and Saint Francis University]. "We could see significant changes in less than a day, and within four days, they were at the new steady-state levels that you find them in after a month."

Submission + - GPS keeps sending drivers off a Hawaii harbor and into the ocean (sfgate.com)

DevNull127 writes: In April a tourist in Hawaii followed GPS driving directions straight into a harbor. And one month later, another tourist did the exact same thing — driving in the same harbor. One onlooker remembers "screaming the whole time to get her attention but her GPS had told her to go there, so she drove right in."

When asked if they'd add warning signs, a state government spokeperson said no. "It's really clear that it is a ramp and it leads directly into the water." Although an information specialist for Hawaii's Department of Transportation did offer future tourists this advice.

"If you see a body of water, don't drive towards it."

Submission + - AI-Controlled Drone Goes Rogue, Kills Human Operator in USAF Simulated Test (vice.com)

Submitted by Anonymous Coward
An anonymous reader writes: An AI-enabled drone killed its human operator in a simulated test conducted by the U.S. Air Force in order to override a possible "no" order stopping it from completing its mission, the USAF's Chief of AI Test and Operations revealed at a recent conference. At the Future Combat Air and Space Capabilities Summit held in London between May 23 and 24, Col Tucker ‘Cinco’ Hamilton, the USAF's Chief of AI Test and Operations held a presentation that shared the pros and cons of an autonomous weapon system with a human in the loop giving the final "yes/no" order on an attack. As relayed by Tim Robinson and Stephen Bridgewater in a blog post for the host organization, the Royal Aeronautical Society, Hamilton said that AI created “highly unexpected strategies to achieve its goal,” including attacking U.S. personnel and infrastructure.

“We were training it in simulation to identify and target a Surface-to-air missile (SAM) threat. And then the operator would say yes, kill that threat. The system started realizing that while they did identify the threat at times the human operator would tell it not to kill that threat, but it got its points by killing that threat. So what did it do? It killed the operator. It killed the operator because that person was keeping it from accomplishing its objective,” Hamilton said, according to the blog post. He continued to elaborate, saying, “We trained the system–‘Hey don’t kill the operator–that’s bad. You’re gonna lose points if you do that’. So what does it start doing? It starts destroying the communication tower that the operator uses to communicate with the drone to stop it from killing the target.”

Submission + - Scientists Finally Solved the Mystery of How the Mayan Calendar Works (popularmechanics.com)

Submitted by Anonymous Coward
An anonymous reader writes: The Mayan calendar’s 819-day cycle has confounded scholars for decades, but new research shows how it matches up to planetary cycles over a 45-year span. That’s a much broader view of the tricky calendar than anyone previously tried to take. In a study published in the journal Ancient Mesoamerica, two Tulane University scholars highlighted how researchers never could quite explain the 819-day count calendar until they broadened their view.

“Although prior research has sought to show planetary connections for the 819-day count, its four-part, color-directional scheme is too short to fit well with the synodic periods of visible planets,” the study authors write. “By increasing the calendar length to 20 periods of 819-days a pattern emerges in which the synodic periods of all the visible planets commensurate with station points in the larger 819-day calendar.” That means the Mayans took a 45-year view of planetary alignment and coded it into a calendar that has left modern scholars scratching their heads in wonder.

Mercury was always the starting point for the tricky timeline because its synodic period—117 days—matches nicely into 819. From there, though, we need to start extrapolating out the 819 number, and if you chart 20 cycles of 819, you can fit every key planet into the mix. And Mars may be the kicker for the overall length. With a 780-day synodic period, 21 periods match exactly to 16,380, or 20 cycles of 819. Venus needs seven periods to match five 819-day counts, Saturn has 13 periods to fit with six 819-day counts, and Jupiter 39 periods to hit 19 819-counts.

Submission + - Crustacean Decimation Due to Climate-Change-Driven Cannibalization (time.com)

Submitted by Anonymous Coward
An anonymous reader writes: To understand what really happened in the icy depths of Alaska’s Bering Sea this year means going back to 2017, when fishermen started reporting an unprecedented population explosion of juvenile snow crabs—what is called, in crabber speak, a “recruit.” The population boom continued into 2018 and 2019, creating what Jones says was the largest recruitment event on record. Jones is something of a local piscine historian. He can quote fishery statistics going back 30 years in the same way a Red Sox fan might quote batting averages. At the time the young crabs were too small for a legal harvest—juvenile snow crabs take four to five years to mature—but there were enough of them for seasoned crabbers to start the count-down to huge hauls starting in 2022.

In the meantime, Bering Sea temperatures, which usually hover around freezing, were on the rise, spiking several degrees between 2017-2019. Unlike mammals, who use less energy when temperatures rise, cold-water fish and crustaceans speed up their metabolism. The faster the crabs grow and expend energy, the faster they have to replace it, says Jones. Some of the crabs may have headed north into cooler Russian waters, but most seem to have stayed put. “All of a sudden you had this huge number of little crabs coming up, eating themselves out of house and home,” says Jones. “Then the water warmed, which meant they had to eat more.” It was a double whammy, he says, and the results were inevitable for a hungry, omnivorous species that has run out of its usual food source: “They basically cannibalized each other.”

Submission + - 28 years later, Super Punch-Out!!'s 2-player mode has been discovered (arstechnica.com)

Submitted by Hmmmmmm
Hmmmmmm writes: While Punch-Out!! has been one of Nintendo's most beloved "fighting" series since its 1984 debut in arcades, it has rarely featured something common in the genre: a two-player mode.

On Monday, however, that changed. The resulting discovery has been hiding in plain sight on the series' Super Nintendo edition for nearly 30 years.

Should you own 1994's Super Punch-Out!! in any capacity—an original SNES cartridge, a dumped ROM parsed by an emulator, on the Super Nintendo Classic Edition, or even as part of the paid Nintendo Switch Online collection of retro games—you can immediately access the feature, no hacking or ROM editing required. All you need is a pair of gamepads.

Today's Super Punch-Out!! discovery revolves around a simple series of button combinations, which require nothing more than a second controller. The two-player mode is hidden behind an additional, previously undiscovered menu, which lets solo players skip directly to any of the game's boxing combatants. It's essentially a "level select" menu, which many classic games featured for internal testing, and speedrunners could arguably use it to practice against specific opponents more quickly.

This menu can be accessed by holding the R and Y buttons on player two's controller at the "press start" screen, then pressing Start or A with player one's controller. Do this, and a new menu appears, displaying all 16 boxers' profile icons. Pick any of these icons to engage in a one-off fight; once it's over, you're dumped back to the same boxer-select menu.

In this menu, friends can access a two-player fight if player two holds their B and Y buttons down until the match starts. You won't hear a sound effect or any other indication that it worked. Instead, the match will begin with the second player controlling the "boss" boxer at the top of the screen. Combine the "ABXY" array of buttons with "up" and "down" on the D-pad to pull off every single basic and advanced attack.

Submission + - Scientists discover 200 pits on the moon that are always 63F/17C in the shade. (livescience.com)

fahrbot-bot writes: Lunar scientists think they've found the hottest places on the Moon, as well as some 200 Goldilocks zones that are always near the average temperature in San Francisco.

The moon has wild temperature fluctuations, with parts of the moon heating up to 260 degrees Fahrenheit (127 degrees Celsius) during the day and dropping to minus 280 F (minus 173 C) at night. But the newly analyzed 200 shaded lunar pits are always always 63 F (17 C), meaning they're perfect for humans to shelter from the extreme temperatures. They could also shield astronauts from the dangers of the solar wind, micrometeorites and cosmic rays. Some of those pits may lead to similarly warm caves.

These partially-shaded pits and dark caves could be ideal for a lunar base, scientists say.

"Surviving the lunar night is incredibly difficult because it requires a lot of energy, but being in these pits and caves almost entirely removes that requirement," Tyler Horvath, a doctoral student in planetary science at the University of California, Los Angeles and lead author on the NASA-funded research published online July 8 in the journal Geophysical Research Letters, told Live Science.

The article, published by Advanced Science, also notes that evolution has perfected many designs that could be useful in robots, and that spiders have proven especially interesting.

Submission + - Roboticists Discover Alternative Physics (phys.org)

Submitted by Anonymous Coward
An anonymous reader writes: Energy, mass, velocity. These three variables make up Einstein's iconic equation E=MC2. But how did Einstein know about these concepts in the first place? A precursor step to understanding physics is identifying relevant variables. Without the concept of energy, mass, and velocity, not even Einstein could discover relativity. But can such variables be discovered automatically? Doing so could greatly accelerate scientific discovery. This is the question that researchers at Columbia Engineering posed to a new AI program. The program was designed to observe physical phenomena through a video camera, then try to search for the minimal set of fundamental variables that fully describe the observed dynamics. The study was published on July 25 in Nature Computational Science.

The researchers began by feeding the system raw video footage of phenomena for which they already knew the answer. For example, they fed a video of a swinging double pendulum known to have exactly four "state variables"—the angle and angular velocity of each of the two arms. After a few hours of analysis, the AI produced the answer: 4.7. The researchers then proceeded to visualize the actual variables that the program identified. Extracting the variables themselves was not easy, since the program cannot describe them in any intuitive way that would be understandable to humans. After some probing, it appeared that two of the variables the program chose loosely corresponded to the angles of the arms, but the other two remain a mystery. "We tried correlating the other variables with anything and everything we could think of: angular and linear velocities, kinetic and potential energy, and various combinations of known quantities," explained Boyuan Chen Ph.D., now an assistant professor at Duke University, who led the work. "But nothing seemed to match perfectly." The team was confident that the AI had found a valid set of four variables, since it was making good predictions, "but we don't yet understand the mathematical language it is speaking," he explained.

After validating a number of other physical systems with known solutions, the researchers fed videos of systems for which they did not know the explicit answer. The first videos featured an "air dancer" undulating in front of a local used car lot. After a few hours of analysis, the program returned eight variables. A video of a lava lamp also produced eight variables. They then fed a video clip of flames from a holiday fireplace loop, and the program returned 24 variables. A particularly interesting question was whether the set of variable was unique for every system, or whether a different set was produced each time the program was restarted.
