Oxylus Energy strikes “beautiful balance” to make e-fuels for aviation and shipping

Many airlines and shipping firms say they are going to achieve net zero carbon emissions by 2050, but they don’t yet have a transparent path to attain this goal.

Scientifically, divesting these industries of fossil fuels is feasible; economically, it isn’t. Or no less than not yet, the young startup claims. Oxylus Energy believes he holds the important thing to 1 a part of the equation.

The company was spun out of Yale’s chemistry lab last 12 months and is working to perfect the production of so-called green methanol. Currently, most methanol comes from fossil fuels and is used to make petrochemicals, although it might probably even be used as a transportation fuel. Because of this flexibility, green methanol, which is made without fossil fuels, could free many industries from carbon pollution.

“We think this is one of the most versatile chemicals that can really decarbonize the hard-to-reduce sectors of shipping, aviation, and petrochemicals, which currently account for 11% of emissions,” co-founder and COO Harrison Meyer told TechCrunch.

While electric vehicles have entered consumer and heavy trucking, flying and heavy shipping are entirely depending on energy-hungry fossil fuels to make long-distance journeys. Batteries are too heavy, and switching every little thing to green hydrogen would require expensive retrofitting of planes and ships.

Motorsport fans will note that methanol has been used as a racing fuel for many years, and lots of today’s internal combustion engines can burn the substance with minor modifications. Some ocean-going vessels also I made a changeand while a barrel of methanol doesn’t contain as much energy as other marine fuels like diesel, it’s close enough that the industry is seriously considering its use.

Airlines face a rather greater hurdle because they need green methanol refined right into a form that more closely resembles today’s jet fuel, which might drive up the value.

But what2 savings only come when the methanol itself is produced in a low-emission way. That’s where Oxylus comes in.

Green methanol production is pricey today since it is a multi-step process, and each energy-intensive step is carried out using expensive equipment. Just one in every of these steps, the extraction of green hydrogen, accounts for about 16% of the whole cost, in accordance with Lux Research.

Oxylus Energy’s technology bypasses the necessity for green hydrogen by utilizing a cobalt-based catalyst to facilitate the chemical response needed to supply methanol. The catalyst sits inside an electrolyzer, which uses electricity to separate water and carbon dioxide molecules. Once separated, the hydrogen, oxygen, and carbon atoms mix to form methanol (CH3OH) and oxygen (O2). All of this happens at standard room temperature and pressure, which helps keep costs low.

“As is the case in CO2 electrolysis, you’re always fighting to produce hydrogen,” said CTO Conor Rooney. If too many hydrogen atoms mix to form hydrogen molecules (H2), there’s not enough leftover to make methanol. The chemical structure of the Oxylus catalyst helps steer the response in the appropriate direction, allowing methanol to form when hydrogen is released from the water. “You have to have that beautiful balance,” Rooney said.

Methanol produced by Oxylus will be utilized by the chemical industry to supply a spread of common chemicals, including formaldehyde and acetic acid. With some additional processing and refining, it might probably be transformed right into a sustainable aviation fuel.

The startup told TechCrunch exclusively that it recently raised $4.5 million in a seed round led by Toyota Ventures and Azolla Ventures with participation from Earth Foundry and Connecticut Innovations. The funding will go toward constructing a production-scale reactor that the corporate hopes will help prove its aggressive pricing goals.

“At the renewable energy prices that are contractable today, we will be at or below cost parity with fossil methanol,” said CEO Perry Bakas. “The fundamental question is, can we build a system in the next few years? That’s really a time and money issue that we’re really focused on.”

Bluesky addresses trust and security issues related to abuse, spam and more

Social media startup Bluesky, which is constructing a decentralized alternative to X (formerly Twitter), provided an update Wednesday on the way it’s approaching various trust and security issues on its platform. The company is in various stages of developing and piloting a variety of initiatives focused on coping with bad actors, harassment, spam, fake accounts, video security and more.

To address malicious users or those that harass others, Bluesky says it’s developing recent tools that can have the option to detect when multiple recent accounts are created and managed by the identical person. This could help curb harassment when a foul actor creates several different personas to attack their victims.

Another recent experiment will help detect “rude” replies and forward them to server moderators. Like Mastodon, Bluesky will support a network where self-hosters and other developers can run their very own servers that connect to Bluesky’s server and others on the network. This federation capability is still in early access. But in the long term, server moderators will have the option to resolve how they need to take care of individuals who post rude responses. In the meantime, Bluesky will eventually reduce the visibility of those responses on its app. Repeated rude labels on content will even lead to account-level labels and suspensions, it says.

To curb using lists to harass others, Bluesky will remove individual users from the list in the event that they block the list creator. Similar functionality was recently introduced to Starter Packs, a sort of shared list that will help recent users find people to follow on the platform (check TechCrunch Starter Pack).

Bluesky will even scan lists with offensive names or descriptions to limit the potential of harassing others by adding them to a public list with a toxic or offensive name or description. Those who violate Bluesky’s Community Guidelines might be hidden from the app until the list owner makes changes that align with Bluesky’s policies. Users who proceed to create offensive lists will even face further motion, though the corporate didn’t provide details, adding that the lists are still an area of ​​energetic discussion and development.

In the approaching months, Bluesky also intends to move to handling moderation reports through its app, using notifications relatively than counting on email reports.

To combat spam and other fake accounts, Bluesky is launching a pilot that can attempt to routinely detect when an account is fake, scamming or sending spam to users. Combined with moderation, the goal is to have the option to take motion on accounts inside “seconds of receiving a report,” the corporate said.

One of the more interesting developments is how Bluesky will comply with local laws while still allowing free speech. It will use geotags that allow it to hide some content from users in a particular area to comply with the law.

“This allows Bluesky’s moderation service to maintain flexibility in creating spaces for free expression while also ensuring legal compliance so that Bluesky can continue to operate as a service in these geographic regions,” the corporate shared in a blog post. “This feature will be rolled out on a country-by-country basis, and we will endeavor to inform users of the source of legal requests when legally possible.”

To address potential trust and safety issues with videos which have recently been added, the team is adding features like the flexibility to disable autoplay, ensuring videos are labeled, and providing the flexibility to report videos. They are still evaluating what else might need to be added, which might be prioritized based on user feedback.

When it comes to abuse, the corporate says its general framework is “a question of how often something happens versus how harmful it is.” The company focuses on addressing high-impact, high-frequency issues, in addition to “tracking edge cases that could result in significant harm to a few users.” The latter, while only affecting a small number of individuals, causes enough “ongoing harm” that Bluesky will take motion to prevent abuse, it says.

User concerns will be reported via reports, emails and mentions @safety.bsky.app account.

Apple Airpods Now With FDA-Approved Hearing Aid Feature

Published

By

The newest AirPods are a part of a growing group of hearing aids available over-the-counter.


Apple’s latest Airpods could help those with hearing impairments. The tech company’s software update has been approved by the FDA to be used as hearing aids.

The FDA approved Apple’s hearing aid feature on September 12. The free update, available on AirPods Pro 2, will amplify sounds for the hearing impaired. However, the feature is simply available to adults 18 and older with an iPhone or iPad compatible with iOS 18.

“Today’s approval of over-the-counter hearing aid software for a commonly used consumer audio product is another step that will increase the availability, affordability, and acceptability of hearing support for adults with mild to moderate hearing loss,” said Dr. Michelle Tarver, acting director of the FDA’s Center for Devices and Radiological Health, in a press release. obtained by .

They confirmed the feature’s use after a clinical trial with 118 participants. The results showed that users “achieved similar perceived benefits to those who received a professional fit on the same device.” Apple also announced the brand new development just days before the agency’s approval.

“Hearing health is an essential part of our overall well-being, yet it is often overlooked — in fact, according to Apple’s Hearing Study, as many as 75 percent of people diagnosed with hearing loss go untreated,” said Sumbul Desai, MD, vice chairman of Health at Apple. press release“We’re excited to deliver breakthrough software features in AirPods Pro that put users’ hearing health first, offering new ways to test and get help for hearing loss.”

What’s more, Apple intends its recent AirPods to supply a “world-first” hearing health experience. Noting that 1.5 billion people suffer from hearing loss, the device also goals to forestall and detect hearing problems.

“Your AirPods Pro will transform into your own personalized hearing aid, amplifying the specific sounds you need in real time, such as parts of speech or elements of your environment,” Desai added in a video announcing the event.

The latest AirPods are a part of a growing variety of over-the-counter (OTC) hearing aids. They usually are not only more accessible, but additionally significantly cheaper than prescription medical devices. While they’re designed for individuals with mild to moderate hearing loss, they’ll initially treat those with limited abilities.

AirPods Pro 2 is available now for $249.

LinkedIn collected user data for training purposes before updating its terms of service

LinkedIn scraped user data for training before updating its terms of service

LinkedIn could have trained AI models on user data without updating its terms.

LinkedIn users within the United States — but not within the EU, EEA, or Switzerland, likely as a consequence of data privacy laws in those regions — have the choice to opt out toggle on the settings screen, revealing that LinkedIn collects personal data to coach “AI models to create content.” The toggle isn’t recent. But, as in early reported According to 404 Media, LinkedIn didn’t initially update its privacy policy to handle data use.

The Terms of Service have already been published. updatedbut that sometimes happens well before an enormous change, equivalent to using user data for a brand new purpose like this. The idea is that this offers users the choice to make changes to their account or leave the platform in the event that they do not like the changes. It looks like that is not the case this time.

So what models does LinkedIn train? Its own, the corporate’s says in a Q&A session, including models to put in writing suggestions and post recommendations. But LinkedIn also says that generative AI models on its platform could be trained by a “third-party vendor,” equivalent to its corporate parent Microsoft.

“As with most features on LinkedIn, when you use our platform, we collect and use (or process) data about your use of the platform, including personal data,” the Q&A reads. “This may include your use of generative AI (AI models used to create content) or other AI features, your posts and articles, how often you use LinkedIn, your language preferences, and any feedback you may have provided to our teams. We use this data, in accordance with our privacy policy, to improve or develop the LinkedIn Services.”

LinkedIn previously told TechCrunch that it uses “privacy-enhancing techniques, including redaction and removal of information, to limit personally identifiable information contained in datasets used to train generative AI.”

To opt out of LinkedIn’s data collection, go to the “Data Privacy” section of the LinkedIn settings menu in your computer, click “Data to improve Generative AI,” after which turn off “Use my data to train AI models to create content.” You may try a more comprehensive opt-out through this typebut LinkedIn notes that opting out is not going to affect training that has already taken place.

The nonprofit Open Rights Group (ORG) has asked the Information Commissioner’s Office (ICO), the UK’s independent regulator for data protection laws, to research LinkedIn and other social networks that train on user data by default. Earlier this week, Meta announced it was resuming plans to gather user data for AI training after working with the ICO to simplify the opt-out process.

“LinkedIn is the latest social media company to process our data without asking for our consent,” Mariano delli Santi, a lawyer and policy officer at ORG, said in a press release. “The opt-out model once again proves to be completely inadequate to protect our rights: society cannot be expected to monitor and prosecute every internet company that decides to use our data to train AI. Opt-in consent is not only legally required, but also common sense.”

The Irish Data Protection Commission (DPC), the supervisory authority responsible for monitoring compliance with the GDPR, the EU’s general privacy rules, told TechCrunch that LinkedIn had last week announced that clarifications on its global privacy policy could be published today.

“LinkedIn has informed us that the policy will include an opt-out setting for members who do not want their data used to train AI models that generate content,” a DPC spokesperson said. “This opt-out is not available to EU/EEA members, as LinkedIn does not currently use EU/EEA member data to train or tune these models.”

TechCrunch has reached out to LinkedIn for comment. We will update this text if we hear back.

The need for more data to coach generative AI models has led to more platforms repurposing or otherwise repurposing their vast troves of user-generated content. Some have even taken steps to monetize that content—Tumblr owner Automattic, Photobucket, Reddit, and Stack Overflow are among the many networks licensing data to AI model developers.

Not all of them made opting out easy. When Stack Overflow announced it will begin licensing content, several users deleted their posts in protest — only to see those posts restored and their accounts suspended.
