Spark 2 adds AI, doubles its DSP power to help your guitar rock out
The Spark 2 from Positive Grid looks like a miniature old-school amp, but it is, essentially, a computer with some knobs and a speaker. It has Bluetooth, USB-C, and an associated smartphone app. It needs firmware updates, which can brick the device—ask me how I found this out—and it runs code on DSP chips. New guitar tones can be downloaded into the device, where they run as software rather than as analog electrical circuits in an amp or foot pedal.
In other words, the Spark 2 is the latest example of the "software-ization" of music.
Forget the old image of a studio filled with a million-dollar, 48-track mixing board from SSL or API and bursting with analog amps, vintage mics, and ginormous plate reverbs. Studios today are far more likely to be digital, where people record "in the box" (i.e., they track and mix on a computer running software like Pro Tools or Logic Pro) using digital models of classic (and expensive) amplifiers, coded by companies like NeuralDSP and IK Multimedia. These modeled amp sounds are then run through convolution software that relies on digital impulse responses captured from different speakers and speaker cabinets. They are modified with effects like chorus and distortion, which are all modeled, too. The results can be world-class, and they're increasingly showing up on records.
Study: Megalodon’s body shape was closer to a lemon shark
The giant extinct shark species known as the megalodon has captured the interest of scientists and the general public alike, even inspiring the 2018 blockbuster film The Meg. The species lived some 3.6 million years ago and no complete skeleton has yet been found. So there has been considerable debate among paleobiologists about megalodon's size, body shape and swimming speed, among other characteristics.
While some researchers have compared megalodon to a gigantic version of the stocky great white shark, others believe the species had a more slender body shape. A new paper published in the journal Palaeontologia Electronica bolsters the latter viewpoint, also drawing conclusions about the megalodon's body mass, swimming speed (based on hydrodynamic principles), and growth patterns.
As previously reported, the largest shark alive today, reaching up to 20 meters long, is the whale shark, a sedate filter feeder. As recently as 4 million years ago, however, sharks of that scale likely included the fast-moving predator megalodon (formally Otodus megalodon). Due to incomplete fossil data, we're not entirely sure how large megalodons were and can only make inferences based on some of their living relatives.
Huh? The valuable role of interjections
Listen carefully to a spoken conversation and you’ll notice that the speakers use a lot of little quasi-words—mm-hmm, um, huh? and the like—that don’t convey any information about the topic of the conversation itself. For many decades, linguists regarded such utterances as largely irrelevant noise, the flotsam and jetsam that accumulate on the margins of language when speakers aren’t as articulate as they’d like to be.
But these little words may be much more important than that. A few linguists now think that far from being detritus, they may be crucial traffic signals to regulate the flow of conversation as well as tools to negotiate mutual understanding. That puts them at the heart of language itself—and they may be the hardest part of language for artificial intelligence to master.
“Here is this phenomenon that lives right under our nose, that we barely noticed,” says Mark Dingemanse, a linguist at Radboud University in the Netherlands, “that turns out to upend our ideas of what makes complex language even possible in the first place.”
New research shows bigger animals get more cancer, defying decades-old belief
A longstanding scientific belief about a link between cancer prevalence and animal body size has tested for the first time in our new study ranging across hundreds of animal species.
If larger animals have more cells, and cancer comes from cells going rogue, then the largest animals on Earth—like elephants and whales—should be riddled with tumours. Yet, for decades, there has been little evidence to support this idea.
Many species seem to defy this expectation entirely. For example, budgies are notorious among pet owners for being prone to renal cancer despite weighing only 35 g. Yet cancer only accounts for around 2 percent of mortality among roe deer (up to 35 kg).
Blood Typers is a terrifically tense, terror-filled typing tutor
When you think about it, the keyboard is the most complex video game controller in common use today, with over 100 distinct inputs arranged in a vast grid. Yet even the most complex keyboard-controlled games today tend to only use a relative handful of all those available keys for actual gameplay purposes.
The biggest exception to this rule is a typing game, which by definition asks players to send their fingers flying across every single letter on the keyboard (and then some) in quick succession. By default, though, typing games tend to take the form of extremely basic typing tutorials, where the gameplay amounts to little more than typing out words and sentences by rote as they appear on screen, maybe with a few cute accompanying animations.
Typing "gibbon" quickly has rarely felt this tense or important. Credit: Outer Brain StudiosBlood Typers adds some much-needed complexity to that basic type-the-word-you-see concept, layering its typing tests on top of a full-fledged survival horror game reminiscent of the original PlayStation era. The result is an amazingly tense and compelling action adventure that also serves as a great way to hone your touch-typing skills.
NASA officials undermine Musk’s claims about ‘stranded’ astronauts
Over the last month there has been something more than a minor kerfuffle in the space industry over the return of two NASA astronauts from the International Space Station.
The fate of Butch Wilmore and Suni Williams, who launched on the first crewed flight of Boeing's Starliner spacecraft on June 5, 2024, has become a political issue after President Donald Trump and SpaceX founder Elon Musk said the astronauts' return was held up by the Biden White House.
In February, Trump and Musk appeared on FOX News. During the joint interview, the subject of Wilmore and Williams came up. They remain in space today after NASA decided it would be best they did not fly home in their malfunctioning Starliner spacecraft—but would return in a SpaceX-built Crew Dragon.
The X-37B spaceplane lands after helping pave the way for “maneuver warfare”
The US military's robotic mini-space shuttle dropped out of orbit and glided to a runway in California late Thursday, ending a 434-day mission that pioneered new ways of maneuvering in space.
The X-37B spaceplane touched down on Runway 12 at Vandenberg Space Force Base, California, at 11:22 pm local time Thursday (2:22 am EST Friday), capping its high-flying mission with an automated reentry and landing on the nearly three-mile-long runway at the West Coast's spaceport.
The Space Force did not publicize the spacecraft's return ahead of time, keeping with the Pentagon's policy of secrecy surrounding the X-37B program. This was the seventh flight of an X-37B spaceplane, or Orbital Test Vehicle, since its first foray into orbit in 2010.
What does “PhD-level” AI mean? OpenAI’s rumored $20,000 agent plan explained.
The AI industry has a new buzzword: "PhD-level AI." According to a report from The Information, OpenAI may be planning to launch several specialized AI "agent" products including a $20,000 monthly tier focused on supporting "PhD-level research." Other reportedly planned agents include a "high-income knowledge worker" assistant at $2,000 monthly and a software developer agent at $10,000 monthly.
OpenAI has not yet confirmed these prices, but they have mentioned PhD-level AI capabilities before. So what exactly constitutes "PhD-level AI"? The term refers to models that supposedly perform tasks requiring doctoral-level expertise. These include agents conducting advanced research, writing and debugging complex code without human intervention, and analyzing large datasets to generate comprehensive reports. The key claim is that these models can tackle problems that typically require years of specialized academic training.
Companies like OpenAI base their "PhD-level" claims on performance in specific benchmark tests. For example, OpenAI's o1 series models reportedly performed well in science, coding, and math tests, with results similar to human PhD students on challenging tasks. The company's Deep Research tool, which can generate research papers with citations, scored 26.6 percent on "Humanity's Last Exam," a comprehensive evaluation covering over 3,000 questions across more than 100 subjects.
Measles outbreak hits 208 cases as federal response goes off the rails
The measles outbreak in West Texas and New Mexico has reached 208 cases.
Texas officials reported 198 confirmed cases across nine counties as of Friday, with 23 people requiring hospitalization since the outbreak exploded at the end of January. Most of the cases continue to be in children and teens, with 153 of the 198 cases being between the ages of 0 and 17. Eleven cases have no confirmed age listed. All but five cases are in people who are unvaccinated or have no vaccination record.
Texas officials have so far reported one death in the outbreak in an unvaccinated school-aged child with no underlying health conditions. Media reports have identified the child as being a 6-year-old.
Feds arrest man for sharing DVD rip of Spider-Man movie with millions online
A 37-year-old Tennessee man was arrested Thursday, accused of stealing Blu-rays and DVDs from a manufacturing and distribution company used by major movie studios and sharing them online before the movies' scheduled release dates.
According to a US Department of Justice press release, Steven Hale worked at the DVD company and allegedly stole "numerous 'pre-release' DVDs and Blu-rays" between February 2021 and March 2022. He then allegedly "ripped" the movies, "bypassing encryption that prevents unauthorized copying" and shared copies widely online. He also supposedly sold the actual stolen discs on e-commerce sites, the DOJ alleged.
Hale has been charged with "two counts of criminal copyright infringement and one count of interstate transportation of stolen goods," the DOJ said. He faces a maximum sentence of five years for the former, and 10 years for the latter.
Review: Mickey 17’s dark comedic antics make for wild cinematic ride
Oscar-winning director Bong Joon-Ho returns to the big screen this weekend with the sci-fi film Mickey 17. If you're expecting the subtly devastating social commentary of his 2019 drama/horror/thriller-hybrid Parasite, I suspect you'll be disappointed. Mickey 17 is a very different beast in both aesthetic and tone. When the first trailer dropped, I wrote that the film felt like a darkly comedic version of Duncan Jones' 2009 film Moon, with a dash of the surreal absurdity of Terry Gilliam's Brazil (1985) thrown in for good measure. I stand by that assessment, and it proves to be a winning combination.
(Some spoilers below but no major reveals.)
The film is based on the 2022 novel Mickey7 by Edward Ashton. Ashton's inspiration for the novel was the teletransportation paradox—a thought experiment pondering the philosophy of identity that challenges certain notions of the self and consciousness. It started as a short story about what Ashton called "a crappy immortality" and expanded from there into a full-length novel. (Ashton also penned a sequel, Antimatter Blues, which was published in 2023.)
Nearly 1 million Windows devices targeted in advanced “malvertising” spree
Nearly 1 million Windows devices were targeted in recent months by a sophisticated "malvertising" campaign that surreptitiously stole login credentials, cryptocurrency, and other sensitive information from infected machines, Microsoft said.
The campaign began in December, when the attackers, who remain unknown, seeded websites with links that downloaded ads from malicious servers. The links led targeted machines through several intermediary sites until finally arriving at repositories on Microsoft-owned GitHub, which hosted a raft of malicious files.
Chain of eventsThe malware was loaded in four stages, each of which acted as a building block for the next. Early stages collected device information, presumably to tailor configurations for the later ones. Later ones disabled malware detection apps and connected to command-and-control servers; affected devices remained infected even after being rebooted.
Music labels will regret coming for the Internet Archive, sound historian says
On Thursday, music labels sought to add nearly 500 more sound recordings to a lawsuit accusing the Internet Archive (IA) of mass copyright infringement through its Great 78 Project, which seeks to digitize all 3 million three-minute recordings published on 78 revolutions-per-minute (RPM) records from about 1898 to the 1950s.
If the labels' proposed second amended complaint is accepted by the court, damages sought in the case—which some already feared could financially ruin IA and shut it down for good—could increase to almost $700 million. (Initially, the labels sought about $400 million in damages.)
IA did not respond to Ars' request for comment, but the filing noted that IA has not consented to music labels' motion to amend their complaint.
“They curdle like milk”: WB DVDs from 2006–2008 are rotting away in their cases
Although digital media has surpassed physical media in popularity, there are still plenty of reasons for movie buffs and TV fans to hold onto, and even continue buying, DVDs. With physical media, owners are assured that they'll always be able to play their favorite titles, so long as they take care of their discs. While digital copies are sometimes abruptly ripped away from viewers, physical media owners don't have to worry about a corporation ruining their Friday night movie plans. At least, that's what we thought.
It turns out that if your DVD collection includes titles distributed by Warner Bros. Home Entertainment, the home movie distribution arm of Warner Bros. Discovery (WBD), you may one day open up the box to find a case of DVD rot.
Recently, Chris Bumbray, editor-in-chief of movie news and reviews site JoBlo, detailed what would be a harrowing experience for any film collector. He said he recently tried to play his Passage to Marseille DVD, but “after about an hour, the disc simply stopped working.” He said “the same thing happened” with Across the Pacific. Bumbray bought a new DVD player but still wasn’t able to play his Desperate Journey disc. The latter case was especially alarming because, like a lot of classic films and shows, the title isn’t available as a digital copy.
Bad vibes? Google may have screwed up haptics in the new Pixel Drop update
Google released its scheduled March Pixel Drop earlier this week, adding AI scam detection, multi-camera streaming, and—possibly—buggy haptics. Pixel owners have been grumbling about the feel of vibrations, which have been described as "springy" and "hollow." Others say the haptics have gotten distractingly harsh in some places.
Android devices have long trailed Apple when it comes to haptic feedback—the latter's Taptic Engine generally puts other phones to shame with its power and precision. However, Google has made great progress with Pixel phones. It occasionally gloats about how much Pixel haptics have improved. It would seem that this attention to detail is not born out in the latest update, though.
Some of this confusion may be down to the addition of notification cooldown, a feature that was previously only in the Android 16 beta. This opt-out feature aims to reduce the annoyance of receiving multiple notifications in quick succession. The first ping you get in a two-minute period will be normal, but if you get another within a few seconds, it will have lower volume and vibration intensity. It tapers off until notifications don't make any additional fuss. You can still find all those notifications in their usual home in the drop-down shade.
AMD says top-tier Ryzen 9900X3D and 9950X3D CPUs arrive March 12 for $599 and $699
AMD's Ryzen 7 9800X3D is probably the best CPU you can buy if you're trying to put together a fast gaming PC, thanks to its eight Zen 5 CPU cores and extra helping of 3D V-Cache. You don't really need more CPU cores than this to play games, and most games benefit from the extra cache more than they do from a bit of extra clock speed.
AMD announced today that it's following up the 9800X3D with two higher-end X3D processors next week. The 12-core Ryzen 9 9900X3D and 16-core Ryzen 9 9950X3D are both launching on March 12 for $599 and $699, respectively, the same as the launch pricing for the last-generation 7900X3D and 7950X3D but a couple hundred dollars more expensive than the current street pricing for the Ryzen 9900X and 9950X.
AMD recommends the 9900X3D and 9950X3D to people whose gaming PCs also do other heavy-duty non-gaming work or for streamers whose gaming PCs are simultaneously running other apps. But they might also appeal to people who would normally just buy a 9800X3D because that processor has been difficult to find at its $479 MSRP since launching last fall. If a 9800X3D already costs nearly $600, why not spring for a faster chip if you can get one?
After less than a day, the Athena lander is dead on the Moon
Intuitive Machines announced on Friday morning that its Athena mission to the surface of the Moon, which landed on its side, has ended.
"With the direction of the Sun, the orientation of the solar panels, and extreme cold temperatures in the crater, Intuitive Machines does not expect Athena to recharge," the company said in a statement. "The mission has concluded and teams are continuing to assess the data collected throughout the mission."
Athena, a commercially developed lander, touched down on the lunar surface on Thursday at 11:28 am local time in Houston (17:28 UTC). The probe landed within 250 meters of its targeted landing site in the Mons Mouton region of the Moon. This is the southernmost location that any probe has landed on the Moon, within a few degrees of the lunar south pole.
Trump says bitcoin reserve will change everything. Crypto fans aren’t so sure.
Ahead of the first-ever White House Crypto Summit Friday, President Donald Trump signed an executive order establishing a strategic bitcoin reserve that a factsheet claimed delivers on his promise to make America the "crypto capital of the world."
Trump's order requires all federal agencies currently holding bitcoins seized as part of a criminal or civil asset forfeiture proceeding to transfer those bitcoins to the Treasury Department, which itself already has a store of bitcoins. Additionally, any other digital assets forfeited will be collected in a separate Digital Assets Stockpile.
But while Trump likely anticipates that bitcoin fans will be over the moon about this news—his announcement of the reserve and looser crypto regulations helped send bitcoin's price to its all-time high of $109,000 in January, Reuters noted—some cryptocurrency enthusiasts were clearly disappointed that Trump's order confirmed that the US currently has no plans to buy any more bitcoins at this time.
Maserati kills electric version of MC20 supercar for lack of demand
Electric motors are, in so many ways, much better than internal combustion engines. They don't waste most of the energy you put into them as heat and sound, they're easy to control, and they make huge amounts of torque almost instantly. Having recently driven BMW's 430i and i4 back to back over the course of two weeks, the electric version was easier in traffic and more responsive on a twisty road. Electric wins, then. Except at the very high end, it seems.
Because even though electric motors can pack a punch, people paying big money for super- and hypercars are increasingly disinterested in those cars being electrified. So much so that Maserati has canceled the all-electric version of the MC20.
The MC20 debuted in 2020. No longer associated with Ferrari after that brand was spun out and IPO'd, the MC20 could offer a full carbon-fiber monocoque and an engine with very clever F1-derived combustion technology, undercutting its now-independent Italian competitor to the tune of more than $100,000 in the process.
White House may seek to slash NASA’s science budget by 50 percent
Although the Trump administration will not publicly release its budget request for at least a few more weeks, senior agency officials are starting to be briefed on the president's priorities.
This includes NASA. As expected, the president's plan for the space agency includes some significant shakeups, including a desire to move elements of NASA headquarters to field centers around the country. However, in perhaps the most drastic change, the White House seeks to massively cut funding for science programs at the space agency.
Multiple people familiar with the White House proposal said cuts to NASA's "Science Mission Directorate" could be as high as 50 percent. These sources emphasized that no decisions are final, and there are some scenarios in which the cuts to NASA's science programs would be less. But the intent is to slash science.
