Did Capturing Carbon from the Air Just Get Easier? (berkeley.edu) 121

"We passed Berkeley air — just outdoor air — into the material to see how it would perform," says U.C. Berkeley chemistry professor Omar Yaghi, "and it was beautiful.

"It cleaned the air entirely of CO2," Yaghi says in an announcement from the university. "Everything."

SFGate calls it "a discovery that could help potentially mitigate the effects of climate change..." Yaghi's lab has worked on carbon capture since the 1990s and began work on these crystalline structures in 2005. The innovative substance has lots of tiny holes, making it "great for storing gases or liquids, much like a sponge holds water," Yaghi said... While it could take one to two years for the powder to be usable in large-scale applications, Yaghi co-founded Atoco, an Irvine company, to commercialize his research and expand it beyond just carbon capture and storage.
"Capturing carbon from the air just got easier," says the headline on the anouncement from the university, which explains why this technology is crucial: [T]oday's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases. Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million, 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 degreesC (2.7 degreesF) above preexisting global averages.

A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions... According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground. UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree.

Their research was published this week in the journal Nature.

And it's also interesting that they're using AI, according to the university's announcement: Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change. "We're very, very excited about blending AI with the chemistry that we've been doing," he said.
Another potential use could be for harvesting water from desert air for drinking water, Yaghi told SFGate. But he seems very focused specifically on carbon capture.

"Another thing is that we need a strong determination among officials and industries to make carbon capture a high priority. Things have to change, but I believe that direct carbon capture from air is very doable."

One Argument Why Data Caps Are Not a Problem (fierce-network.com) 176

NoWayNoShapeNoForm writes: OpenVault believes that data caps on broadband are not a problem because most people do not exceed their existing data caps. OpenVault contends that people that do exceed their broadband data caps are simply being forgetful — leaving a streaming device on 24x7, or deploying unsecure WiFi access points, or reselling their service within an apartment building.

Yes, there may be some ISPs that have older networks that they have not upgraded. Or maybe they are unable to increase network capacity in "the middle mile" of their networks, but the Covid pandemic certainly encouraged many ISPs to upgrade their networks and capacity while many ISPs that had broadband data caps ended that feature.

Perhaps the biggest problem, according to OpenVault, is that most broadband users do not really have any idea how much bandwidth they "consume" every month. If Internet access is a service that people want to treat as a "utility", then you have to ask, Would they keep the water running after finishing their shower?

In the article Ookla's VP of Smart Communities adds that "Scrolling through social media feeds for hours can 'push' hundreds of videos to the user, many of which may be of no interest — they just start running." So the main driver for usage-based billing wasn't to increase revenue, OpenVault CEO Mark Trudeau tells the site, but to "balance the network a little more..." (Though he then also adds that sometimes a subscriber could also be reselling broadband service in their apartment building, "And that's not even legal.")

"If one or two customers on a given node is causing issues for 300 others, where those 300 are not getting the service that they paid for, then that's a problem right?" he said.

Having said that, the article also points out that "Many major fiber providers, like AT&T, Frontier, Google Fiber and Verizon Fios, don't have data caps at all."

Singapore Approves 2,600-Mile Undersea Cable to Import Solar Energy from Australia (newatlas.com) 91

"The world's largest renewable energy and transmission project has received key approval from government officials," reports New Atlas.

Solar power from Australia will be carried 2,672 miles (4,300 kilometers) to Singapore over undersea cables in what's being called "the Australia-Asia Power Link project." Reuters reports that SunCable "aims to produce 6 gigawatts of electricity at a vast solar farm in Northern Australia and ship about a third of that to Singapore via undersea cable."

More from New Atlas: [The project] will start by constructing a mammoth solar farm in Australia's Northern Territory to transmit around-the-clock clean power to [the Australian city] Darwin, and also export "reliable, cost-competitive renewable energy" to Singapore... with a clean energy generation capacity of up to 10 gigawatts, plus utility scale onsite storage. [The recently-obtained environmental approval] also green lights an 800-km (~500-mile) overhead transmission line between the solar precinct and Murrumujuk near Darwin...

If all of the dominoes line up perfectly, supply of the first clean electricity is estimated to start in the early 2030s. An overview graphic on the project page shows that the eventual end game for the Powell Creek development appears to be the generation of up to 20 GW of peak solar power and have some 36-42 GWh of battery storage on site.

Researchers Discover Flaws In Five End-to-End Encrypted Cloud Services (scworld.com) 33

SC World reports: Several major end-to-end encrypted cloud storage services contain cryptographic flaws that could lead to loss of confidentiality, file tampering, file injection and more, researchers from ETH Zurich said in a paper published this month.

The five cloud services studied offer end-to-end encryption (E2EE), intended to ensure files can not be read or edited by anyone other than the uploader, meaning not even the cloud storage provider can access the files. However, ETH Zurich researchers Jonas Hofmann and Kien Tuong Truong, who presented their findings at the ACM Conference on Computer and Communications Security (CCS) last week, found serious flaws in four out of the five services that could effectively bypass the security benefits provided by E2EE by enabling an attacker who managed to compromise a cloud server to access, tamper with or inject files.

The E2EE cloud storage services studied were Sync, pCloud, Seafile, Icedrive and Tresorit, which have a collective total of about 22 million users. Tresorit had the fewest vulnerabilities, which could enable some metadata tampering and use of non-authentic keys when sharing files. The other four services were found to have more severe flaws posing a greater risk to file confidentiality and integrity.

BleepingComputer reports that Sync is "fast-tracking fixes," while Seafile "promised to patch the protocol downgrade problem on a future upgrade." And SC World does note that all 10 of the tested exploits "would require the attacker to have already gained control of a server with the ability to read, modify and inject data.

"The authors wrote that they consider this to be a realistic threat model for E2EE services, as these services are meant to protect files even if such a compromise was to occur."

NASA Astronaut in Good Health After Experiencing 'Medical Issue' After SpaceX Splashdown (nasa.gov) 17

"After safely splashing down on Earth as part of NASA's SpaceX Crew-8 mission Friday, a NASA astronaut experienced a medical issue," NASA reported Friday.

But today there's an update: After an overnight stay at Ascension Sacred Heart Pensacola in Florida, the NASA astronaut was released and returned to NASA's Johnson Space Center in Houston Saturday. The crew member is in good health and will resume normal post-flight reconditioning with other crew members.

As part of NASA's SpaceX Crew-8 mission [SpaceX's eighth crew-rotation mission to the ISS], the astronaut was one of four crewmates who safely splashed down aboard their SpaceX Dragon spacecraft near Pensacola on October 25. The crew members completed a 235-day mission, 232 days of which were spent aboard the International Space Station conducting scientific research.

To protect the crew member's medical privacy, specific details on the individual's condition and identity will not be shared.

Inside the U.S. Government-Bought Tool That Can Track Phones At Abortion Clinics (404media.co) 235

Slashdot reader samleecole writes: Privacy advocates gained access to a powerful tool bought by U.S. law enforcement agencies that can track smartphone locations around the world. Abortion clinics, places of worship, and individual people can all be monitored without a warrant.

An investigation into tracking tool Locate X shows in the starkest terms yet how it and others — based on smartphone location data sold to various U.S. government law enforcement agencies, including state entities — could be used to monitor abortion clinic patients. This comes as more states contemplate stricter or outright bans on abortion...

Researchers Develop New Lithium Extraction Method With 'Nearly Double the Performance' (pv-magazine.com) 21

PV Magazine reports: Researchers in Australia and China have developed an innovative technology enabling direct lithium extraction from difficult-to-process sources like saltwater, which they say represents a substantial portion of the world's lithium potential.

Until now, up to 75% of the world's lithium-rich saltwater sources have remained untapped because of technical limitations, but given predictions that global lithium supply could fall short of demand as early as 2025, the researchers believe they have a game-changing solution. Their technology is a type of nanofiltration system that uses ethylenediaminetetraacetic acid, or EDTA, as a chelating agent to selectively separate lithium from other minerals, especially magnesium, which is often present in brines and difficult to remove.

"With some predicting global lithium supply could fall short of demand as early as 2025, the innovative technology sets a new standard in lithium processing," writes SciTechDaily: The work, co-led by Dr Zhikao Li, from the Monash Suzhou Research Institute and the Department of Chemical and Biological Engineering, and Professor Xiwang Zhang from the University of Queensland, promises to meet the surging demand for lithium and paves the way for more sustainable and efficient extraction practices... "Our technology achieves 90 percent lithium recovery, nearly double the performance of traditional methods, while dramatically reducing the time required for extraction from years to mere weeks," Dr. Li said.

The technology also turns leftover magnesium into a valuable, high-quality product that can be sold, reducing waste and its impact on the environment. Beyond its advanced efficiency, the EALNF system brings innovation to address major environmental concerns associated with lithium extraction. Unlike conventional methods that deplete vital water resources in arid regions, the technology produces freshwater as a by-product.

Dr Li said the system was flexible and ready for large-scale use, meaning it can quickly expand from testing to full industrial operations. "This breakthrough is crucial for avoiding a future lithium shortage, making it possible to access lithium from hard-to-reach sources and helping power the shift to clean energy."

"Our scalable process minimizes environmental impact while maximizing resource utilization," according to the researchers' article in Nature Sustainability, "thereby catalysing the shift toward a more sustainable future."

Egyptian Blogger/Developer Still Held in Prison 28 Days After His Release Date (eff.org) 51

In 2004 Alaa Abd El Fattah answered questions from Slashdot's readers about organizing the first-ever Linux installfest in Egypt.

In 2014 he was arrested for organizing poltical protests without requesting authorization, according to Wikipedia, and then released on bail — but then sentenced to five years in prison upon retrial. He was released in late March of 2019, but then re-arrested again in September by the National Security Agency, convicted of "spreading fake news" and jailed for five years...

Wikipedia describes Abd El-Fattah as an "Egyptian-British blogger, software developer and a political activist" who has been "active in developing Arabic-language versions of software and platforms." But this week an EFF blog post noticed that his released date had recently passed — and yet he was still in prison: It's been 28 days since September 29, the day that should have seen British-Egyptian blogger, coder, and activist Alaa Abd El Fattah walk free. Egyptian authorities refused to release him at the end of his sentence, in contradiction of the country's own Criminal Procedure Code, which requires that time served in pretrial detention count toward a prison sentence. [Human Rights Watch says Egyptian authorities are refusing to count more than two years of pretrial detention toward his time served. Amnesty International has also called for his release.] In the days since, Alaa's family has been able to secure meetings with high-level British officials, including Foreign Secretary David Lammy, but as of yet, the Egyptian government still has not released Alaa...

Alaa deserves to finally return to his family, now in the UK, and to be reunited with his son, Khaled, who is now a teenager. We urge EFF supporters in the UK to write to their MP to place pressure on the UK's Labour government to use their power to push for Alaa's release.

Last month the EFF wrote:: Over 20 years ago Alaa began using his technical skills to connect coders and technologists in the Middle East to build online communities where people could share opinions and speak freely and privately. The role he played in using technology to amplify the messages of his fellow Egyptians — as well as his own participation in the uprising in Tahrir Square — made him a prominent global voice during the Arab Spring, and a target for the country's successive repressive regimes, which have used antiterrorism laws to silence critics by throwing them in jail and depriving them of due process and other basic human rights.

Alaa is a symbol for the principle of free speech in a region of the world where speaking out for justice and human rights is dangerous and using the power of technology to build community is criminalized...

DTrace for Linux Comes to Gentoo (gentoo.org) 14

It was originally created back in 2005 by Sun Microsystems for its proprietary Solaris Unix systems, "for troubleshooting kernel and application problems on production systems in real time," explains Wikipedia. "DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes," explains its Wikipedia entry.

But this week, Gentoo announced: The real, mythical DTrace comes to Gentoo! Need to dynamically trace your kernel or userspace programs, with rainbows, ponies, and unicorns — and all entirely safely and in production?! Gentoo is now ready for that!

Just emerge dev-debug/dtrace and you're all set. All required kernel options are already enabled in the newest stable Gentoo distribution kernel...

Documentation? Sure, there's lots of it. You can start with our DTrace wiki page, the DTrace for Linux page on GitHub, or the original documentation for Illumos. Enjoy!

Password Manager Bitwarden Makes Changes to Address Concerns Over Open Source Licensing (github.com) 10

Bitwarden describes itself as an "open source password manager for business." But it also made a change its build requirement which led to an issue on the project's GitHub page titled "Desktop version 2024.10.0 is no longer free software."

In the week that followed Bitwarden's official account on X.com promised a fix was coming. "It seems a packaging bug was misunderstood as something more, and the team plans to resolve it. Bitwarden remains committed to the open source licensing model in place for years, along with retaining a fully featured free version for individual users." And Thursday Bitwarden followed through with new changes to address the concerns.

The Register reports the whole episode started because of a new build requirement added in a pull request a couple of weeks ago titled "Introduce SDK client." This SDK is required to compile the software from source — either the Bitwarden server or any of its client applications... [But the changed license had warned "You may not use this SDK to develop applications for use with software other than Bitwarden (including non-compatible implementations of Bitwarden) or to develop another SDK."]
Phoronix picks up the story: The issue of this effectively not making the Bitwarden client free software was raised in this GitHub issue... Bitwarden founder and CTO Kyle Spearrin has commented on the ticket... "Being able to build the app as you are trying to do here is an issue we plan to resolve and is merely a bug." The ticket was subsequently locked and limited to collaborators.
And Thursday it was Bitwarden founder and CTO Kyle Spearrin who again re-appeared in the Issue — first thanking the user who had highlighted the concerns. "We have made some adjustments to how the SDK code is organized and packaged to allow you to build and run the app with only GPL/OSI licenses included." The sdk-internal package references in the clients now come from a new sdk-internal repository, which follows the licensing model we have historically used for all of our clients (see LICENSE_FAQ.md for more info). The sdk-internal reference only uses GPL licenses at this time. If the reference were to include Bitwarden License code in the future, we will provide a way to produce multiple build variants of the client, similar to what we do with web vault client builds.

The original sdk repository will be renamed to sdk-secrets, and retains its existing Bitwarden SDK License structure for our Secrets Manager business products. The sdk-secrets repository and packages will no longer be referenced from the client apps, since that code is not used there.

Delta Sues CrowdStrike Over Software Update That Prompted Mass Flight Disruptions (reuters.com) 78

An anonymous reader quotes a report from Reuters: Delta Air Lines on Friday sued cybersecurity firm CrowdStrike in a Georgia state court after a global outage in July caused mass flight cancellations, disrupted travel plans of 1.3 million customers and cost the carrier more than $500 million. Delta's lawsuit filed in Fulton County Superior Court called the faulty software update from CrowdStrike "catastrophic" and said the firm "forced untested and faulty updates to its customers, causing more than 8.5 million Microsoft Windows-based computers around the world to crash." [...]

Delta, which has purchased CrowdStrike products since 2022, said the outage forced it to cancel 7,000 flights, impacting 1.3 million passengers over five days. "If CrowdStrike had tested the faulty update on even one computer before deployment, the computer would have crashed," Delta's lawsuit says. "Because the faulty update could not be removed remotely, CrowdStrike crippled Delta's business and created immense delays for Delta customers." Delta said that as part of its IT-planning and infrastructure, it has invested billions of dollars "in licensing and building some of the best technology solutions in the airline industry."

Boeing Explores Sale of Space Business (theverge.com) 60

According to the Wall Street Journal, Boeing is weighing the sale of its space division. "The plans, which are reportedly at an early stage, could involve Boeing offloading the Starliner spacecraft and its projects supporting the International Space Station," reports The Verge. From the report: Boeing is facing a series of predicaments, including a fraud charge over 737 Max plane crashes and Starliner issues that left two astronauts at the ISS for months. Just this week, a Boeing-made satellite for Intelsat stopped working and fell apart suddenly after suffering an "anomaly."

"We're better off doing less and doing it better than doing more and not doing it well," Boeing CEO Kelly Ortberg said during an earnings call this week. "Clearly, our core of commercial airplanes and defense systems are going to stay with the Boeing Company for the long run. But there's probably some things on the fringe there that we can be more efficient with or that distract us from our main goal here."

However, sources tell the WSJ that Boeing will likely continue to oversee the Space Launch System, which will eventually help bring NASA astronauts back to the Moon. It's also reportedly expected to hang onto its commercial and military satellite businesses.
