CMF, the budget-friendly sub-brand Nothing announced back in August, has launched its first products: A smartwatch, a pair of earbuds and a GaN charger. The $69 Watch Pro comes with a 1.96-inch AMOLED display and built-in GPS. Its battery can last for up to 13 days, and it can make and receive calls, so long as it's connected to a phone via Bluetooth, but it doesn't seem to have access to an app store. The device is largely health-focused with various features that include monitors for real-time heart rate, blood oxygen saturation, as well as sleep and stress levels. It also provides hydration and movement reminders and the ability to set personalized goals.

Meanwhile, CMF's new earbuds are called the Buds Pro, and they cost $49. They offer up to 45 dB of active noise cancellation and a system comprised of an algorithm and optimally positioned openings at the top of each bud to minimize sound interference caused by winds. The earbuds are also capable of eliminating background noise to ensure voice clarity in phone calls with their AI noise reduction algorithm. CMF says they can last for up to 11 hours with one charge, provided ANC remains switched off. With the power provided by its charging case, it could take up to 39 hours before users will have to plug them in. 

Finally, CMF has also launched a 65W GaN charger with two USB-C ports and a USB-A port. It has the capability to bring a Nothing Phone 2's battery to 50 percent in just 25 minutes, the company says. Nothing will be selling these products in limited quantities in India and the UK on September 30, though it did say that it will make the devices available for sale in other markets soon.

The ARC nerve stimulation therapy system from startup Onward Medical passed another developmental milestone on Wednesday, as the company announced the first successful installation of its brainwave-driven implantable electrode array to restore function and feeling to a patient’s hands and arms. The news comes just five months after the researchers implanted a similar system in a different patient to help them regain a more natural walking gait.

The ARC system used differs depending on how what issue it's being applied to. The ARC-EX is an external, non-invasive stimulator array that sits on the patient’s lower back and helps regulate their bladder control and blood pressure, as well as improving limb function and control. Onward’s lower limb study from May employed the EX along with a BCI controller from CEA-Clinatec to create a “digital bridge” spanning the gap in the patient’s spinal column.

The study published Wednesday instead utilized the ARC-IM, an implantable version of the company’s stimulator array which is installed near the spinal cord and is controlled through wearable components and a smartwatch. Onward had previously used the IM system to enable paralyzed patients to stand and walk short distances without assistance, for which it was awarded an FDA Breakthrough Device Designation in 2020.

Medical professionals led by by neurosurgeon Dr. Jocelyne Bloch, implanted the ARC-IM and the Clinatec BCI into a 46-year-old patient suffering from a C4 spinal injury, in mid-August. The BCI’s hair-thin leads pick up electrical signals in the patient’s brain, convert those analog signals into digital ones that machines can understand, and then transmits them to a nearby computing device where a machine learning AI interprets the patient’s electrical signals and issues commands to the implanted stimulator array. The patient thinks about what they want to do and these two devices work to translate that intent into computer-controlled movement.

How well that translation occurs remains to be seen while the patient learns and adapts to the new system. “The implant procedures involving the Onward ARC-IM and Clinatec BCI went smoothly,” Dr. Bloch said in an press release. “We are now working with the patient to use this cutting-edge innovation to recover movement of his arms, hands, and fingers. We look forward to sharing more information in due course.”

“If the therapy continues to show promise, it is possible it could reach patients by the end of the decade,” Onward CEO Dave Marver said in a statement to Engadget. “It is important to note that we do not expect people with spinal cord injury to wait that long for Onward to commercialize an impactful therapy - we hope to commercialize our external spinal cord stimulation solution, ARC-EX Therapy, to restore hand and arm function in the second half of 2024.”

Onward Medical among a quickly expanding field of BCI-based startups working to apply the fledgling technology to a variety of medical maladies. Those applications include loss of limb and self-regulatory function due to stroke, traumatic brain or spinal cord injury, physical rehabilitation from those same injuries, as well as a critical means of communication for people living with Locked-In Syndrome.

The Writers Guild of America (WGA) has voted to officially lift its strike order, over half a year since it stopped work and demanded a better contract with the Alliance of Motion Picture and Television Producers (AMPTP). Writers can officially go back to work after 12:01 AM PT on September 27, even though the organization has yet to hold the final ratification vote. WGA's decision comes shortly after it held a series of negotiation sessions with producers and reached a tentative agreement, with one of the key sticking points being the use of generative AI. 

Now, the WGA has released a summary of the terms of its new contract, and it prominently features protections against the use of generative AI in the writing process. To start with, generative AI can't be used to write or rewrite literary material, and anything it produces cannot be considered source material. Writers can choose to use AI if the company or studio consents to it, but studios can't force writers to use AI software like ChatGPT. If a studio already has materials to hand over to a writer, they have to disclose if those materials include anything generated by AI. Finally, the "exploitation of writers' material to train AI" is prohibited under the new agreement. 

In addition to AI-related protections, writers are also getting higher pay, increased pension and health contributions, as well as higher payment and residuals for streaming projects. Foreign streaming residuals will be based on the number of subscribers for services available globally, while some domestic projects' residuals will be based on hours streamed by subscribers in the US. The new contract will be valid for three years until May 1, 2026. 

While the WGA strike has now ended, SAG-AFTRA's is still ongoing. The group even voted in favor of a strike authorization for performers working in video games recently to give it added leverage in its negotiations with video game producers. 

X is getting closer to releasing its long-promised alerts that will notify users about whether or not their account has been “shadowbanned.” Andrea Conway, a designer at X, offered a preview of the upcoming feature that Elon Musk first promised last year.

Conway shared two mock-ups: an alert in the notifications tab, as well as an informational page that explains why X may limit the visibility of some accounts. “We have found that your account potentially contains sensitive media — such as graphic, violent, nudity, sexual behavior, hateful symbols, or other sensitive content,” it explains.

“We may cover your posts with a warning so people who don’t want to see sensitive content can avoid it. The reach of your account and its content may also be restricted, such as being excluded from the For You and Following timelines, recommended notifications, trends, and search results.”

Underneath the message is an appeal button, so users can request X revisit its initial decision. Conway also said that users would likely be able to view their account status outside of the app’s notifications tab, but didn’t elaborate on how that might work. She added that the wording and user interface hasn't yet been finalized. 

The company previously introduced a labeling feature for individual tweets that have been “visibility limited” for violating the company’s rules. But the latest update will take that a step further as the restrictions will be visible at the account level, not just for specific tweets.

The feature touches on what has long been a hot-button issue for Twitter, and now X. The company has for years limited the reach of accounts that break its rules. Under Twitter’s previous management, the practice was known as “visibility filtering.” But the company didn’t publicly share details about the practice, or which accounts it limited, which fueled conspiracy theories about “shadowbans.”

The issue came into the spotlight again last year after Musk turned over internal emails and other company records to independent journalists, who published records of Twitter executives discussing visibility filtering. Musk later promised that a future update “will show your true account status, so you know clearly if you’ve been shadowbanned, the reason why and how to appeal.”

Of course visibility filtering and so-called “shadowbanning” were never exactly the same thing. As Recodepointed out last year, Twitter for years said that shadowbanning refers to “deliberately making someone’s content undiscoverable to everyone except the person who posted it, unbeknownst to the original poster.” Whereas visibility filtering — both under Jack Dorsey and now Musk’s leadership — hides tweets from search, recommendations and other surfaces, but doesn’t make them completely invisible.

In any case, the forthcoming update should add some additional transparency — and, potentially, more controversy — to the practice. It’s not clear when the feature will make an official debut, but Conway said the company “should have more to share on this soon.”

If you spend much time around industrial processes, you may have seen a vibrating bowl feeder at work. It’s a clever but simple machine that takes an unruly pile of screws or nuts and bolts, and delivers them in a line the correct way up. They do this by shaking the pile of fasteners in a specific way — a spiral motion which encourages them to work to the edge of the pile and align themselves on a spiral track which leads to a dispenser. It’s a machine [Fraens] has made from 3D printed parts, and as he explains in the video below the break, there’s more to this than meets the eye.

The basic form of the machine has a weighted base and an upper bowl on three angled springs. Between the two is an electromagnet, which provides the force for the vibration. The electromagnet needed to be driven with a sine wave which he makes with an Arduino and delivers as PWM via an H-bridge, but the meat of this project comes in balancing the force and frequency with the stiffness of the springs. He shows us the enormous pile of test prints made before the final result was achieved, and it’s a testament to the amount of work put into this project. The final sequence of a variety of objects making the march round the spiral is pure theatre, but we can see his evident satisfaction in a job well done.

Oddly this isn’t the first bowl feeder we’ve seen, though it may be one of the most accomplished. We particularly like this tiny example for SMD parts.

The US’ outdated electrical grid is not equipped to handle rising demands for renewable energy or the “new normal” threats of extreme weather and cyberattacks. This is according to energy security watchdog, SAFE, whose Grid Security Project found that problems like blackouts and shortages are becoming increasingly common. Without updates to both policy and infrastructure, SAFE warns, these issues are only likely to get worse.

In a new report, SAFE points to events like the deadly 2021 power crisis in Texas, when millions of people were left without electricity during a winter storm, and a 2022 shooting at a North Carolina substation that led to outages for more than 40,000 people. While instances like these may once have been considered rare events, they’re unfortunately becoming par for the course. The report also highlights sophisticated cyberattacks abroad, like the historic hack into Ukraine’s power grid in 2015, as examples of what the US grid could find itself up against.

“Extreme weather events, cyber espionage and domestic terror attacks, combined with increasing demand on aging infrastructure have turned the occasional power failure into alarmingly common events in cities across the United States,” said Thomas Coleman, executive director of SAFE’s Grid Security Project, in a statement published alongside the report.

The rapid transition away from fossil fuels will only add to the strain. Electric vehicles, which draw directly from the grid, have seen exponential adoption in recent years, and the system is still limited in its capacity to deliver energy from renewable sources like wind and solar to populated areas. The current infrastructure won’t be able to reliably keep up with greater energy generation and transmission needs.

According to SAFE, “the progeny of the infrastructure on which our great-grandparents once relied is increasingly inadequate to serve as the foundation of today’s modern economy.” In other words, the grid needs updating, and fast.

X, the company previously known as Twitter, could soon find itself in hot water with European Union officials due to the amount of misinformation on its platform. The platform has an outsize role in the spread of misinformation, according to a new EU report.

The EU shared its findings in its first report on platforms’ handling of mis and disinformation as part of the Digital Services Act. The sweeping law, which recently went into effect, requires major platforms to disclose details about their handling of misinformation. Dozens of companies have additionally agreed to a voluntary “Code of Practice” on disinformation. X announced in May that it was pulling out of the agreement, though the company said it would adhere to the stricter disinformation policies required under the DSA.

The report found that X outstripped many of its larger peers when it comes to the volume of disinformation on its platform, and the engagement such posts attract. “X … is the platform with the largest ratio of mis/disinformation posts,” European Commission Vice President Vera Jourova said in a statement. The report also found that X ranked the highest in discoverability of misinformation and disinformation, followed by Facebook and Instagram.

X didn’t respond to a request for comment. In a series of tweets from its Global Affairs account, the company disputed the “framing” of the data and said it remains “committed to complying with the DSA.”

In a statement, Jourova said that all of the major platforms need to “to adjust their actions to reflect that there is a war in the information space waged against us.” She said that upcoming elections within the EU “will be an important test for the Code that platforms signatories should not fail.”

She also said that Musk would not be “off the hook” just because Twitter pulled out of the code of practice, according to comments reported by The Guardian. “My message for Twitter/X is you have to comply. We will be watching what you do.”

Ford said on Monday that it was suspending construction of a Michigan battery factory for electric vehicles. The automaker didn’t specify its exact reasons for the shutdown as United Auto Workers (UAW) strikes continue. However, it stated (viaThe New York Times) that it was “pausing work and limiting spending on construction on the Marshall project until we’re confident about our ability to competitively operate the plant.”

The factory was established earlier this year to produce battery tech licensed from China’s Contemporary Amperex Technology Co (CATL). It isn’t yet clear if the suspension is temporary or permanent.

The news came ahead of President Biden’s trip to Michigan on Tuesday to protest alongside picketing workers. Ford didn’t state whether its decision was related to the strikes. The UAW’s walkout against the Big Three automakers expanded to 38 locations in 20 states last week.

The $3.5 billion factory, scheduled to open in 2026, is slated to produce lithium-iron-phosphate batteries for EVs — supplying jobs for at least 2,500 autoworkers and spurring domestic EV battery production. However, the project has been flanked by uncertainty as the Biden Administration weighs regulations that could prevent US companies from working with select Chinese businesses.

The UAW has previously given Ford credit for bringing more concessions to the negotiating table during the strike than GM or Stellantis, going as far as sparing Ford from the recent walkout expansions. The union is asking for pay raises, a shorter workweek, protection against inflation and other worker concessions. In an interview this month, Ford CEO Jim Farley claimed meeting the union’s demands “would force Ford to scrap its investments in electric vehicles.”

UAW President Shawn Fain described Ford’s closure as “a shameful, barely-veiled threat by Ford to cut jobs.” He posted on X (formerly Twitter) on Monday, “Closing 65 plants over the last 20 years wasn’t enough for the Big Three, now they want to threaten us with closing plants that aren’t even open yet. We are simply asking for a just transition to electric vehicles and Ford is instead doubling down on their race to the bottom.”
