Neuralink, the Elon Musk-led startup that the multi-entrepreneur founded in 2017, is working on technology that’s based around ‘threads’ which it says can be implanted in human brains with much less potential impact to the surrounding brain tissue vs. what’s currently used for today’s brain-computer interfaces. “Most people don’t realize, we can solve that with a chip,” Musk said to kick off Neuralink’s event, talking about some of the brain disorders and issues the company hopes to solve.
Musk also said that long-term Neuralink really is about figuring out a way to “achieve a sort of symbiosis with artificial intelligence.” “This is not a mandatory thing,” he added. “This is something you can choose to have if you want.”
For now, however, the aim is medical and the plan is to use a robot that Neuralink has created that operates somewhat like a “sewing machine” to implant this threads, which are incredibly thin I(like, between 4 and 6 μm, which means about one-third the diameter of the thinnest human hair), deep within a person’s brain tissue, where it will be capable of performing both read and write operations at very high data volume.
All of this sounds incredibly far-fetched, and to some extent it still is: Neuralink’s scientists told The New York Times in a briefing on Monday that the company has a “long way to go” before it can get anywhere near offering a commercial service. The main reason for breaking cover and talking more freely about what they’re working on, the paper reported, is that they’ll be better able to work out in the open and publish papers, which is definitely an easier mode of operation for something that requires as much connection with the academic and research community as this.
Neuralink co-founder and president Max Hodak told the NYT that he’s optimistic Neuralink’s tech could theoretically see use somewhat soon in medical use, including potential applications enabling amputees to regain mobility via use of prosthetics and reversing vision, hearing or other sensory deficiencies. It’s hoping to actually begin working with human test subjects as early as next year, in fact, including via possible collaboration with neurosurgeons at Stanford and other institutions.
The current incarnation of Neuralink’s tech would involve drilling actual holes into a subject’s skull in order to insert the ultra thin threads, but future iterations will shift to using lasers instead to create tiny holes that are much less invasive and essentially not felt by a patient, Hodak told the paper. Working on humans next year with something that meets this description for a relatively new company might seem improbable, but Neuralink did demonstrate its technology used on a laboratory rat this week, with performance levels that exceed today’s systems in terms of data transfer. The data from the rat was gathered via a USB-C port in its head, and it provided about 10x more what the best current sensors can offer, according to Bloomberg.
Neurlalink’s advances vs. current BCI methods also include the combined thinness and flexibility of the ‘threads’ used, but one scientist wondered about their longevity when exposed to the brain, which contains a salt mix fluid that can damage and ultimately degrade plastics over time. The plan is also that the times electrodes implanted in the brain will be able to communicate wirelessly with chips outside the brain, providing real time monitoring with unprecedented freedom of motion, without any external wires or connections.
Elon Musk is bankrolling the majority of this endeavour as well as acting as its CEO, with $100 million of the $158 million its raised so far coming from the SpaceX and Tesla CEO. It has 90 employees thus far, and still seems to be hiring aggressively based on its minimal website (which basically only contains job ads). Elon Musk also noted at the outset of today’s presentation that the main reason for the event was in fact to recruit new talent.
Ring Car Cam leaks: This could be Amazon’s Alexa dash-cam
Details and what appears to be an image of Ring’s upcoming Car Cam have leaked, with the connected dash cam expected to add security both when the vehicle is parked and while it’s on the move. The newest addition to Ring’s line-up was actually announced in September 2020 as part of Amazon’s big device launch, though at the time no pictures of the Car Cam hardware itself were shared.
Still, Ring’s description painted a fairly comprehensive picture of what it was intended to do. As well as tracking bumps and attempted break-ins, and notifying owners via the Ring smartphone app, it can also be used to record journeys and summon emergency services in the case of an accident being detected.
If you’re being pulled over by the police, meanwhile, saying “Alexa, I’m being pulled over” will automatically begin video and audio recording. At the same time as that’s being uploaded to the cloud, the system will send a notification to pre-selected family members to let them know the stop has taken place. Ring said there would be a physical privacy shutter, too, and a choice of WiFi or LTE connectivity. The whole thing would be $199.99, though cellular plans would be on top of that.
Since then, we’ve not heard anything more about the new dash camera. A leak on The Tape Drive, though, has revealed what it could look like, and it’s certainly an unusual design.
The camera assembly looks to be mounted on some sort of bracket, either to be positioned above the dashboard or potentially hung from above the rearview mirror. There’s presumably a fish-eye camera on both sides – only visible from one side in the render – to capture footage both inside and outside of the car.
As for functionality, ZatzNotFunny spotted a seemingly prematurely-published Ring Car Cam information document on the company’s support site. It reconfirms some of the details which Ring told us late last year, but also adds a few extra tidbits.
For example, the camera will connect via the vehicle’s data port, not just hook up to a USB or 12V outlet for power. “Ring Car Cam easily installs directly to the OBD-II port in your vehicle, located behind your steering wheel in most cars,” Ring explains. “It securely attaches to the windshield and dashboard of the car, and the cable can be neatly tucked away and out of sight.”
It’s unclear what extra data Ring might be gathering by using that approach. The OBD-II port typically grants access to various driving metrics, and though originally intended as a way for vehicle technicians to diagnose faults and issues in increasingly computerized models, has also gained traction as a way for third-party devices to tap that same stream of information. Amazon had also announced Ring Car Alarm, a cellularly-connected dongle that plugs into the ODB-II port.
The Ring Car Cam itself won’t require a subscription, though you won’t get all of the features in that case. “You can access video stored locally on the device via the Ring app when the car is within range of wifi,” the company explains. “With an optional Ring connectivity plan, you can access video from anywhere via LTE as well as advanced features like Emergency Crash Assist.”
The connectivity plan for Ring Car Cam will also unlock features like real-time tracking, to help locate a stolen vehicle.
What remains to be seen is how Ring Car Cam will fit into Ring’s existing sharing policies with police departments. The Amazon-owned company has found itself mired in controversy in recent years, after inking deals with law enforcement that saw many requests for footage from connected security cameras and video doorbells. Ring had been accused of fueling privacy infringement and supporting racial profiling.
Earlier this month, the company announced a new policy around sharing with public safety and law enforcement agencies. Moving forward, such agencies will ahem to request information or video from communities through a publicly-viewable category on Ring’s Neighbors app. This new section, “Request for Assistance,” will allow communities to see just what sort of data is being shared, Ring says.
“All Request for Assistance posts will be publicly viewable in the Neighbors feed, and logged on the agency’s public profile,” Ring explains. “This way, anyone interested in knowing more about how their police agency is using Request for Assistance posts can simply visit the agency’s profile and see the post history.”
YouTube on iOS PiP makes it much easier to watch videos while multitasking
YouTube is now rolling out the ability for all users to watch videos with picture-in-picture mode, which reduces the video players to a small floating screen on one’s phone or tablet. This feature won’t be limited to only premium customers as some had previously speculated, though those premium customers will get access to the PiP support first.
Android users have had access to YouTube’s picture-in-picture mode for a while; it has become increasingly useful as devices get larger, higher-resolution displays, leaving ample room for using more than one app at a time. With PiP, someone can watch a video in a small corner of their device’s display while doing something else, such as browsing social media, messaging, or playing games.
There have been concerns over recent months that YouTube wouldn’t only make its picture-in-picture mode available to paying Premium subscribers on iOS, but that’s not the case, according to confirmation given to MacRumors.
The feature is now rolling out to all iOS users in the United States, with Premium customers getting it first followed by free users ‘soon.’ Some iOS users have already had access to the YouTube picture-in-picture feature, though its availability has been touch and go with it working only sometimes.
The official support will eliminate the need to deal with difficult workarounds and buggy Safari streaming, though you may need to remain patient if you’re not a Premium user. The feature will be most useful on larger iPhone models where there’s enough screen space to watch a video in the mini player and engage in a second activity.
Researchers say they’ve found the ideal strategy to pay off student loans
When many people near college graduation, they begin to contemplate how they’ll deal with the student loans they’ve racked up over the past few years. The burden — which grows more substantial with every generation — can result in stress and, if not managed properly, may throw one’s life plans off track for several years. Mathematicians with the University of Colorado at Boulder may have a solution, explaining that they developed a mathematical model to explore the ideal repayment strategy.
Generally speaking, college graduates get a brief grace period after graduation during which time they aren’t required to make payments on their loans. Two different options are available once payments start: an income-based repayment strategy that involves paying a certain amount monthly based on one’s salary or simply throwing as much money at the loan as possible to pay it off in a shorter period of time.
In many cases, graduates are often advised to pay the loans off as quickly as possible if the funding amount is on the smaller side. On the flip side, graduates are typically told to take the income-based repayment option if they’ve taken out a substantial amount of funds in the form of student loans. The new study suggests a hybrid approach may be more ideal.
The mathematical model takes into account things like compounding interest rates, the income tax that may need to be paid, and more. The findings indicate that some graduates may benefit from a hybrid-style repayment approach that involves paying off as much as possible for the first several years, then switching over to an income-based repayment plan for the remainder of the balance.
The team of researchers hasn’t made their work available as a calculator for the public, but they do plan to improve it and potentially make it available to existing repayment calculators that may integrate the model. The ideal repayment method will ultimately depend on personal factors that must be accounted for, including things like anticipated salary and more.
