First ever drone-delivered kidney is no worse for wear – TechCrunch

Published

on

Drone delivery really only seems practical for two things: take-out and organ transplants. Both are relatively light and also extremely time-sensitive. Well, experiments in flying a kidney around Baltimore in a refrigerated box have yielded positive results — which also seems promising for getting your pad thai to you in good kit.

The test flights were conducted by researchers at the University of Maryland there, led by surgeon Joseph Scalea. He has been frustrated in the past with the inflexibility of air delivery systems, and felt that drones represent an obvious solution to the last-mile problem.

Scalea and his colleagues modified a DJI M600 drone to carry a refrigerated box payload, and also designed a wireless biosensor for monitoring the organ while in flight.

After months of waiting, their study was assigned a kidney that was healthy enough for testing but not good enough for transplant. Once it landed in Baltimore, the team loaded it into the container and had it travel 14 separate missions of various distances and profiles. The longest of these was three miles, a realistic distance between hospitals in the area, and the top speed achieved was 67.6 km/h, or about 42 mph.

Biopsies of the kidney were taken before and after the flights, and also after a reference flight on a small aircraft, which is another common way to transport organs medium distances.

The results are good: Despite the potential threats of wind chill and heat from the motors of the drone (though this was mitigated by choosing a design with a distal motor-rotor setup), the temperature of the box remained at 2.5 degrees Celsius, just above freezing. And no damage appeared to have been done by the drones’ vibrations or maneuvers.

Restrictions on drones and on how organs can be transported make it unlikely that this type of delivery will be taking place any time soon, but it’s studies like this that make it possible to challenge those restrictions. Once the risk has been quantified, then kidneys, livers, blood and other tissues or important medical supplies may be transported this way — and in many cases, every minute counts.

One can also imagine the usefulness of this type of thing in disaster situations, when not just ordinary aircraft but also land vehicles may have trouble getting around a city. Drones should be able to carry much-needed supplies — but before they do, they should definitely be studied to make sure they aren’t going to curdle the blood or anything.

The specifics of the study are detailed in a paper published in the IEEE Journal of Translational Engineering in Health and Medicine.

USB installer tool removes Windows 11’s Microsoft account requirements (and more)

Published

on

Enlarge / The Rufus tool will offer to modify your Windows 11 install media when you create it. The workaround for the Microsoft account requirement is new to the 3.19 beta.

Andrew Cunningham

One of the new “features” coming to the Windows 11 22H2 update is a Microsoft account requirement for all new installs, regardless of whether you are using the Home or Pro version of the operating system. And that’s too bad, because the 22H2 update corrects a few of Windows 11’s original shortcomings while adding some nice quality-of-life improvements.

An easy workaround for this requirement is the Rufus USB formatting tool, which can create USB install media for Windows and all kinds of other operating systems. Rufus has already offered some flags to remove Windows 11’s system requirements checks from the installer, removing the need for clunky Windows Registry edits and other workarounds. But the beta of version 3.19 will also remove the Microsoft account requirement for new installs, making it easy to set up a new Windows PC with a traditional local account.

When setting up Windows 11, make sure not to connect your PC to the Internet before creating your user account. This trick worked to circumvent the Microsoft account requirement in Windows 11 Pro and some of the later versions of Windows 10 but is being removed entirely from Windows 11 22H2. The Rufus tool merely reverts to the pre-22H2 status quo.

If you’re using Rufus to avoid Windows 11’s system requirements, your system will still be “unsupported” once you have Windows 11 up and running. That means putting up with periodic reminder messages about unsupported hardware and the vague threat that Microsoft may eventually stop providing updates and security patches for unsupported systems. On the other hand, Rufus also doesn’t keep Windows 11’s TPM and security features from working once the OS is installed, so if you want to create a single USB installer that will cover both supported and unsupported systems, Rufus makes that possible.

Microsoft provides its own media creation tools for people who want to make USB install drives for Windows 10 or Windows 11, but it obviously doesn’t offer the same circumventions for the company’s requirements.

iFixit and Google launch official Pixel parts store

Published

on

iFixit

The iFixit and Google partnership that was announced in April is now live. iFixit says that genuine parts for Google smartphones are now for sale in “the US, UK, Canada, Australia, and European countries where Pixel is available.”

It looks like iFixit is offering screens, batteries, and rear camera assemblies for most models of the Pixel phone, along with smaller odds and ends like adhesive and cooling graphite tape. Despite the official partnership with Google, we wouldn’t call the iFixit Pixel store a comprehensive source of Pixel parts. For the Pixel 6 and 6 Pro—which are currently in production and should have tons of available parts—you can’t buy replacement glass back panels, charging ports, front cameras, or any of the delicate cables you could accidentally rip while you’re taking the phone apart. Just compare the official Pixel 6 Pro parts list, which has only six items, to any of the iPhone part lists, which have about 30 parts, and you can see there are a lot of missing items.

iFixit says it’s just getting started, though, and that it will “continue to add more types of parts to our catalog” for the Pixel 2 and later. For the Pixel 6a, which comes out at the end of July, iFixit is promising “a full selection” of parts “as soon as possible.”

iFixit says Google has continually been improving the reparability of its devices, although the repair site never actually scored the Pixel 6 or 6 Pro. (iFixit’s last full Pixel teardown was on the Pixel 4 XL in 2019.) iFixit also praised Google’s willingness to make software repair tools available online, like an easy-to-use OS flashing tool and a fingerprint reader calibration tool for the Pixel 6. If Google is really concerned about device longevity and reducing e-waste, we would like to see the company match its competitors when it comes to software support, where Google’s three years of major OS updates are still lagging behind Samsung (four years) and Apple (five years).

Apple outs its invite-only program that rewards VIP forum members 

Published

on

Samuel Axon

Apple made its Community+ Program common knowledge this week. Similar to other tech companies like Dell, HP, and Microsoft, Apple has been rewarding the knowledgeable volunteers who frequently contribute to its online support community.

As spotted via iClarified on Wednesday, Apple launched the Apple Community+ Program webpage, which details a program that annually invites a small number of forum members to enjoy special rewards. An Apple rep told Ars Technica that while the webpage is new, the program “has been around for a few years.” It’s likely that since only a small number of people get to participate in the program, there hasn’t been much chatter about it before the page’s launch.

The Community+ members receive “special perks, white-glove experiences, and more,” according to the program’s page, but Apple didn’t specify what that means, and the company declined to provide Ars Technica more details about the rewards.

Apple also didn’t specify the boxes you have to check to get an invite. The Community+ page does say, however, that invitees are “high-level community members” who are “engaged and active in the community,” “share quality content and helpful answers to build their reputation,” and are role models for the forum.

Regular Apple support community members already receive points for participating in activities like asking or answering a question or having one of their answers marked as “helpful” by other community members. Gathering virtual points can lead to virtual rewards, like the ability to have a custom avatar image or access to The Lounge, where you and other high-ranking members can have discussions.

The Community+ Program promises better perks than that. Again, we don’t have specifics, but we can look at similar tech perks programs for ideas.

As noted by The Verge, Microsoft support forum members have been receiving MVP awards for more than 20 years, with over 4,000 reportedly earning the title so far. Perks include early access to Microsoft products and an invite to the annual Global MVP Summit at Microsoft’s Redmond, Washington, headquarters.

For a couple of years, Dell has been rewarding its most elite community members with invites to online and in-person events and providing new product testings and internal resources. Meanwhile, HP’s Expert program rewards include invites to virtual and live events and the opportunity to speak with HP employees.

It’s good to hear that Apple has also been rewarding its most helpful forum members, who can save hours of time for Apple customers and employees, free of charge. Without a detailed look at those perks, though, it’s unclear just how appreciative Apple is.
