renzema (Slashdot reader #84,617) wants suggestions for a point-to-point video conferencing system "to connect the kids to their grandparents... We live in Europe and they in the U.S., but we both have gigabit internet and can sustain upwards of 100mb between our houses." I've been spoiled at work with super high quality Cisco systems... Currently, we have Amazon Echos, but the video quality on these (at least for Sweden/U.S. calls) is really lacking.

We've tried Facetime as well, and while the video quality is much better, the inconvenience of needing to use it on an iPad or phone is quite high (or starting a call with them, then them needing to move to the computer...) Ideally I would love Facetime on an Apple TV with a camera that follows us. We have played a bit with the phone-as-a-camera thing with Facetime and Apple TV, but the sound was not great...

I'm willing to invest in hardware, up to a few hundred dollars per site, if this can really be bulletproof and give a consistently high quality video connection. Ideally it would be standalone hardware that does not need a computer to be running all the time.
There's one problem that can't be solved: calling the grandparents' phone when they're out of the house and not available to talk. But the dream solution involves using a TV to make and receive video calls. "When a call is received, it would power on the TV and 'ring'."

The wishlist?

• High quality picture
• No echo in large rooms. Handles people sitting a few meters away from the TV.
• "Would really prefer no monthly fees."

What's the best home videoconferencing system?

Casey Newton, former senior editor at the Verge, weighs in on Platformer about the arrest of Telegram CEO Pavel Durov.

"Fending off onerous speech regulations and overzealous prosecutors requires that platform builders act responsibly. Telegram never even pretended to." Officially, Telegram's terms of service prohibit users from posting illegal pornographic content or promotions of violence on public channels. But as the Stanford Internet Observatory noted last year in an analysis of how CSAM spreads online, these terms implicitly permit users who share CSAM in private channels as much as they want to. "There's illegal content on Telegram. How do I take it down?" asks a question on Telegram's FAQ page. The company declares that it will not intervene in any circumstances: "All Telegram chats and group chats are private amongst their participants," it states. "We do not process any requests related to them...."

Telegram can look at the contents of private messages, making it vulnerable to law enforcement requests for that data. Anticipating these requests, Telegram created a kind of jurisdictional obstacle course for law enforcement that (it says) none of them have successfully navigated so far. From the FAQ again:

To protect the data that is not covered by end-to-end encryption, Telegram uses a distributed infrastructure. Cloud chat data is stored in multiple data centers around the globe that are controlled by different legal entities spread across different jurisdictions. The relevant decryption keys are split into parts and are never kept in the same place as the data they protect. As a result, several court orders from different jurisdictions are required to force us to give up any data. [...] To this day, we have disclosed 0 bytes of user data to third parties, including governments.

As a result, investigation after investigation finds that Telegram is a significant vector for the spread of CSAM.... The company's refusal to answer almost any law enforcement request, no matter how dire, has enabled some truly vile behavior. "Telegram is another level," Brian Fishman, Meta's former anti-terrorism chief, wrote in a post on Threads. "It has been the key hub for ISIS for a decade. It tolerates CSAM. Its ignored reasonable [law enforcement] engagement for YEARS. It's not 'light' content moderation; it's a different approach entirely.
The article asks whether France's action "will embolden countries around the world to prosecute platform CEOs criminally for failing to turn over user data." On the other hand, Telegram really does seem to be actively enabling a staggering amount of abuse. And while it's disturbing to see state power used indiscriminately to snoop on private conversations, it's equally disturbing to see a private company declare itself to be above the law.

Given its behavior, a legal intervention into Telegram's business practices was inevitable. But the end of private conversation, and end-to-end encryption, need not be.

The Washington Post writes that Telegram's "anything-goes approach" to its 950 million users "has also made it one of the internet's largest havens for child predators, experts say...."

"Durov's critics say his public idealism masks an opportunistic business model that allows Telegram to profit from the worst the internet has to offer, including child sexual abuse material, or CSAM... " [Telegram is] an app of choice for political organizing, including by dissidents under repressive regimes. But it is equally appealing for terrorist groups, criminal organizations and sexual predators, who use it as a hub to share and consume nonconsensual pornography, AI "deepfake" nudes, and illegal sexual images and videos of exploited minors, said Alex Stamos, chief information security officer at the cybersecurity firm SentinelOne. "Due to their advertised policy of not cooperating with law enforcement, and the fact that they are known not to scan for CSAM, Telegram has attracted large groups of pedophiles trading and selling child abuse materials," Stamos said.

That reach comes even though many Telegram exchanges don't actually use the strong forms of encryption available on true private messaging apps, he added. Telegram is used for private messaging, public posts and group chats. Only one-to-one conversations can be encrypted in a way that even Telegram can't access them. And that occurs only if users choose the option, meaning the company could turn over everything else to governments if it wanted to... French prosecutors argue that Durov is in fact responsible for Telegram's emergence as a global haven for illegal content, including CSAM, because of his reluctance to moderate it and his refusal to help authorities police it, among other allegations...

David Kaye, a professor at University of California, Irvine School of Law and former U.N. special rapporteur on freedom of expression... said that while Telegram has at times banned groups and taken down [CSAM] content in response to law enforcement, its refusal to share data with investigators sets it apart from most other major tech companies. Unlike U.S.-based platforms, Telegram is not required by U.S. law to report instances of CSAM to the National Center for Missing and Exploited Children, or NCMEC. Many online platforms based overseas do so anyway — but not Telegram. "NCMEC has tried to get them to report, but they have no interest and are known for not wanting to work with [law enforcement agencies] or anyone in this space," a NCMEC spokesperson said.
The Post also writes that Telegram "has repeatedly been revealed to serve as a tool to store, distribute and share child sexual imagery." (They cite several examples, including two different men convicted to minimum sentences of at least 10 years for using the service to purchase CSAM and solicit explicit photos from minors.)

Longtime Slashdot reader mmell writes: Regular Slashdot users will certainly be aware of the saga unfolding between the country of Brazil and X. Reuters has already reported that what I have to relay here will come as no surprise to Elon Musk, but reporting on CNN confirms that Brazilian Justice Alexandre de Moraes has ordered X to suspend operations in Brazil until X names a representative to appear on X's behalf in Brazilian Courts.

Is this the end of X or some brilliant Machiavellian ploy on the part of Elon Musk? Only time and the informed and spirited debate of the users here at /. can be sure. Here's a recap of the saga, as told by X's Grok-2 chatbot: The Beginning: Alexandre de Moraes, a Brazilian Supreme Court Justice with a reputation for tackling misinformation, especially around elections, found himself at odds with Elon Musk, the space-faring, electric-car magnate turned social media mogul. The conflict kicked off when Moraes ordered X to block certain accounts in Brazil, part of his broader crackdown on what he deemed as misinformation.

The Escalation: Musk, never one to shy away from a fight, especially when it involves what he perceives as free speech issues, declared on X that he would not comply with Moraes' orders. This defiance wasn't just a tweet; it was a digital declaration of war. Musk accused Moraes of overstepping his bounds, betraying the constitution, and even likened him to Darth Vader in a less than flattering comparison. Moraes, not amused, opened an investigation into Musk for obstruction of justice, accusing him of inciting disobedience and disrespecting Brazil's sovereignty. The stakes were raised with fines of around $20,000 per day for each reactivated account, and threats of arresting X employees in Brazil.

The Drama Unfolds: The internet, as it does, had a field day. Posts on X ranged from Musk supporters calling Moraes a dictator to others backing Moraes, arguing he was defending democracy against foreign billionaires. The conflict became a global spectacle, with Musk's posts drawing international attention, comparing the situation to a battle for free speech versus censorship. Musk, in true Musk fashion, didn't just stop at defiance. He shared all of Moraes' demands publicly, suggesting users use VPNs, and even hinted at closing X's operations in Brazil, which eventually happened, citing the need to protect staff safety.

The Latest Chapter: Recently, X announced the closure of its operations in Brazil, a move seen as the culmination of this legal and ideological battle. Musk framed it as a stand against what he saw as an assault on free speech, while critics viewed it as an overreaction or a strategic retreat.

Pakistani businesses say internet disruptions this month have harmed their businesses [non-paywalled link] and unsettled investors at a time when the country is counting on the information technology sector to help break a cycle of economic crises and bailouts. From a report: The warnings from executives, investors and a leading IT organisation come as internet watchdogs have reported a marked slowdown in connection speeds and service interruptions to applications such as WhatsApp, the Meta-owned messaging platform that is widely used in the country. Nadeem Elahi, managing director for TRG, a venture capital firm that operates Pakistan's biggest outsourcing services provider, said internet connectivity was "by far the worst it has been in the last 12 months."

"If we want to be a global business processing operation destination, then 100 per cent reliable connectivity is essential for customers," he said, estimating that the quality of connection had degraded by 30 to 40 per cent. Technology is one of Pakistan's few standout sectors, and Islamabad is relying on software developers and IT freelancers to help lift the country out of a chronic foreign exchange rut that has sent it to the IMF for support two dozen times. IT exports rose 24 per cent to $3.2bn, an all-time high, in the 12 months to the end of June, according to the State Bank of Pakistan.

Mukesh Ambani, Asia's richest man and the chairman of Reliance Industries, said this week that his telecom firm will offer users 100 GB of free cloud storage. Oil-to-retail giant Reliance, which is India's most valuable firm by market cap, has upended the telecom market in India by offering free voice calls and dirt-cheap internet access.

Jio, Reliance's telecom subsidiary, serves 490 million subscribers, more than any rival in India. Jio offers access to at least 2GB of data per day for 14 days to subscribers for a total of $2.3. TechCrunch adds: Reliance plans to offer Jio users up to 100 GB of free cloud storage through its Jio AI Cloud service, set to launch around Diwali in October, Ambani said.

A recent indictment (PDF) of an Alaska man stands out due to the sophisticated use of multiple encrypted communication tools, privacy-focused apps, and dark web technology. "I've never seen anyone who, when arrested, had three Samsung Galaxy phones filled with 'tens of thousands of videos and images' depicting CSAM, all of it hidden behind a secrecy-focused, password-protected app called 'Calculator Photo Vault,'" writes Ars Technica's Nate Anderson. "Nor have I seen anyone arrested for CSAM having used all of the following: [Potato Chat, Enigma, nandbox, Telegram, TOR, Mega NZ, and web-based generative AI tools/chatbots]." An anonymous reader shares the report: According to the government, Seth Herrera not only used all of these tools to store and download CSAM, but he also created his own -- and in two disturbing varieties. First, he allegedly recorded nude minor children himself and later "zoomed in on and enhanced those images using AI-powered technology." Secondly, he took this imagery he had created and then "turned to AI chatbots to ensure these minor victims would be depicted as if they had engaged in the type of sexual contact he wanted to see." In other words, he created fake AI CSAM -- but using imagery of real kids.

The material was allegedly stored behind password protection on his phone(s) but also on Mega and on Telegram, where Herrera is said to have "created his own public Telegram group to store his CSAM." He also joined "multiple CSAM-related Enigma groups" and frequented dark websites with taglines like "The Only Child Porn Site you need!" Despite all the precautions, Herrera's home was searched and his phones were seized by Homeland Security Investigations; he was eventually arrested on August 23. In a court filing that day, a government attorney noted that Herrera "was arrested this morning with another smartphone -- the same make and model as one of his previously seized devices."

The government is cagey about how, exactly, this criminal activity was unearthed, noting only that Herrera "tried to access a link containing apparent CSAM." Presumably, this "apparent" CSAM was a government honeypot file or web-based redirect that logged the IP address and any other relevant information of anyone who clicked on it. In the end, given that fatal click, none of the "I'll hide it behind an encrypted app that looks like a calculator!" technical sophistication accomplished much. Forensic reviews of Herrera's three phones now form the primary basis for the charges against him, and Herrera himself allegedly "admitted to seeing CSAM online for the past year and a half" in an interview with the feds.

Most of the attention today has been focused on California's controversial "kill switch" AI safety bill, which passed the California State Assembly by a 45-11 vote. However, California legislators passed another tech bill this week which requires internet browsers and mobile operating systems to offer a simple tool for consumers to easily opt out of data sharing and selling for targeted advertising. Slashdot reader awwshit shares a report from The Record: The state's Senate passed the landmark legislation after the General Assembly approved it late Wednesday. The Senate then added amendments to the bill which now goes back to the Assembly for final sign off before it is sent to the governor's desk, a process Matt Schwartz, a policy analyst at Consumer Reports, called a "formality." California, long a bellwether for privacy regulation, now sets an example for other states which could offer the same protections and in doing so dramatically disrupt the online advertising ecosystem, according to Schwartz.

"If folks use it, [the new tool] could severely impact businesses that make their revenue from monetizing consumers' data," Schwartz said in an interview with Recorded Future News. "You could go from relatively small numbers of individuals taking advantage of this right now to potentially millions and that's going to have a big impact." As it stands, many Californians don't know they have the right to opt out because the option is invisible on their browsers, a fact which Schwartz said has "artificially suppressed" the existing regulation's intended effects. "It shouldn't be that hard to send the universal opt out signal," Schwartz added. "This will require [browsers and mobile operating systems] to make that setting easy to use and find."

A new study of broadband reliability finds a top-two finish that you might not expect from recent surveys of ISP customer satisfaction: Charter's Spectrum and Comcast's Xfinity, the two largest cable operators in the US. From a report: Opensignal's report, published Thursday, draws on software telemetry collected from April 1 through June 29 of downtime, consistency of service, and how well a provider meets basic thresholds for speed, latency, and other core performance metrics. Spectrum comes in first with a "Reliability Experience" score of 741 out of 1,000, followed by Xfinity with 710, Verizon with 625, AT&T with 546, and T-Mobile with 525. Opensignal chose those five companies to study because each passes more than a third of US homes.

But while Comcast and Charter employ the same basic cable architecture except for a few fiber-to-the-home pockets, Verizon and AT&T have mixed networks. That includes extensive and growing fiber service but also fixed 4G and 5G wireless from Verizon and hybrid-fiber broadband from AT&T, both of which lack fiber's speed and capacity advantages, plus obsolete DSL connectivity. T-Mobile's home connectivity, meanwhile, is almost exclusively fixed wireless.

An anonymous reader quotes a report from the BBC: South Korea's president has urged authorities to do more to "eradicate" the country's digital sex crime epidemic, amid a flood of deepfake pornography targeting young women. Authorities, journalists and social media users recently identified a large number of chat groups where members were creating and sharing sexually explicit "deepfake" images -- including some of underage girls. Deepfakes are generated using artificial intelligence, and often combine the face of a real person with a fake body. South Korea's media regulator is holding an emergency meeting in the wake of the discoveries.

The spate of chat groups, linked to individual schools and universities across the country, were discovered on the social media app Telegram over the past week. Users, mainly teenage students, would upload photos of people they knew -- both classmates and teachers -- and other users would then turn them into sexually explicit deepfake images. The discoveries follow the arrest of the Russian-born founder of Telegram, Pavel Durov, on Saturday, after it was alleged that child pornography, drug trafficking and fraud were taking place on the encrypted messaging app. South Korean President Yoon Suk Yeol on Tuesday instructed authorities to "thoroughly investigate and address these digital sex crimes to eradicate them."

"Recently, deepfake videos targeting an unspecified number of people have been circulating rapidly on social media," President Yoon said at a cabinet meeting. "The victims are often minors and the perpetrators are mostly teenagers." To build a "healthy media culture," President Yoon said young men needed to be better educated. "Although it is often dismissed as 'just a prank,' it is clearly a criminal act that exploits technology to hide behind the shield of anonymity," he said.

The Guardian notes that making sexually explicit deepfakes with the intention of distributing them is punishable by five years in prison or a fine of $37,500.

An anonymous reader quotes a report from TechCrunch: Threads is deepening its ties to the fediverse, also known as the open social web, which powers services like X alternative Mastodon, Pixelfed, PeerTube, Flipboard and other apps. On Wednesday, Meta announced that users on Threads will be able to see fediverse replies on other posts besides their own. In addition, posts that originated through the Threads API, like those created via third-party apps and scheduling services, will now be syndicated to the fediverse. The latter had previously been announced via an in-app message informing users that API posts would be shared to the fediverse starting on August 28. [...]

Since June, users have been able to see fediverse replies on their posts if they enabled fediverse sharing in the app's settings. Once enabled, the sharing option allows users to syndicate their posts across the wider social web and then see how people on other services have responded. Now users will be able to see the fediverse replies on other people's posts, too. This immediately brings more content into Threads, even without a sizable increase in Threads users.

A Meta engineer suggested testing the feature by viewing the replies of larger accounts, like YouTuber Marques Brownlee (@mkbhd), for example. Here, you'll notice a new section that shows how many "fediverse replies" are available above the replies posted to Threads itself. It's worth noting that you have to tap or click on the "fediverse replies" section to actually view what's being said on other servers and by who. Currently, Threads users can like the replies from other servers, but they can't yet reply to them, as the feature is still in beta and under development.

The state-sponsored Chinese hacking campaign known as Volt Typhoon is exploiting a bug in a California-based startup to hack American and Indian internet companies, according to security researchers. From a report: Volt Typhoon has breached four US firms, including internet service providers, and another in India through a vulnerability in a Versa Networks server product, according to Lumen's unit Black Lotus Labs. Their assessment, much of which was published in a blog post on Tuesday, found with "moderate confidence" that Volt Typhoon was behind the breaches of unpatched Versa systems and said exploitation was likely ongoing.

Versa, which makes software that manages network configurations and has attracted investment from Blackrock and Sequoia Capital, announced the bug last week and offered a patch and other mitigations. The revelation will add to concerns over the susceptibility of US critical infrastructure to cyberattacks. The US this year accused Volt Typhoon of infiltrating networks that operate critical US services, including some of the country's water facilities, power grid and communications sectors, in order to cause disruptions during a future crisis, such as an invasion of Taiwan.

Samsung Electronics said it will provide Tizen OS updates for its newer TVs for at least seven years, starting with models released in March this year and some 2023 models. Business Korea reports: [Yoon Seok-woo, President of Samsung Electronics' Visual Display Business Division] emphasized that the seven-year free upgrade for Tizen applied to AI TVs would help Samsung widen the market share gap with Chinese competitors. Tizen, an in-house developed OS, has been applied to over 270 million Samsung smart TVs as of last year, making it the world's largest smart TV platform and a key player in leading the Internet of Things (IoT) era. "AI TV will act as the hub of the AI home, connecting other AI appliances like refrigerators and air conditioners," Yoon explained. "We will expand the AI home era by enabling users to monitor and control peripheral devices through the TV even when it is off or when the user is away." This connectivity is a key differentiator from Chinese competitors, according to Yoon.

In the first half of this year, Samsung Electronics maintained the top spot in the global TV market with a 28.8% market share by revenue. However, the combined market share of Chinese companies TCL and Hisense has reached 22.1%, indicating fierce competition.

An anonymous reader quotes a report from the Financial Times: Ikea is taking on the likes of eBay, Craigslist, and Gumtree with a peer-to-peer marketplace for customers to sell secondhand furniture to each other. Ikea Preowned will be tested in Madrid and Oslo until the end of the year with the aim of rolling out the buying and selling platform globally, according to Jesper Brodin, chief executive of Ingka, the main operator of Ikea stores. [...] Ikea has had a small offering under which it buys used furniture from customers and resells it in store. But the new platform is more ambitious, aiming to tackle the secondhand market for customers selling directly to each other -- an area where Brodin estimates Ikea has a higher market share than in new furniture sales. Customers enter their product, their own pictures, and a selling price, while Ikea's own artificial intelligence-enabled database brings in its own promotional images and measurements. The buyer collects the furniture directly from the seller, who has the option of receiving money or a voucher from Ikea with a 15 percent bonus.

"Very often there is a monopoly or oligopoly on platforms that operate," said Brodin, talking about eBay or digital classified ad services such as Gumtree in the UK and Finn in Norway. Finn has 8,700 items from Ikea listed in Oslo alone. Early offerings on Ikea Preowned include large items such as sofas for up to $670 (600 euros) and wardrobes for $500 (450 euros) as well as smaller items such as a toilet roll holder for $4.50 (4 euros). Listings are free, but Brodin said Ikea could eventually charge "a symbolic fee, a humble fee." He added: "We're going to verify the full scope including the economics. If a lot of people use the offer to get a discount with Ikea -- it's a good way to reconnect with customers. I am very curious. I think it makes business sense." Ikea has previously tested selling its new furniture on third-party platforms such as Alibaba's Tmall in China, but the Preowned platform marks its first foray into secondhand marketplaces. It also dovetails with the retailer's wish to become "circular and climate positive" by 2030.

A university in Taiwan was breached with "a previously unseen backdoor (Backdoor.Msupedge) utilizing an infrequently seen technique," Symantec reports. The most notable feature of this backdoor is that it communicates with a command-and-control server via DNS traffic... The code for the DNS tunneling tool is based on the publicly available dnscat2 tool. It receives commands by performing name resolution... Msupedge not only receives commands via DNS traffic but also uses the resolved IP address of the C&C server (ctl.msedeapi[.]net) as a command. The third octet of the resolved IP address is a switch case. The behavior of the backdoor will change based on the value of the third octet of the resolved IP address minus seven...

The initial intrusion was likely through the exploit of a recently patched PHP vulnerability (CVE-2024-4577). The vulnerability is a CGI argument injection flaw affecting all versions of PHP installed on the Windows operating system. Successful exploitation of the vulnerability can lead to remote code execution.

Symantec has seen multiple threat actors scanning for vulnerable systems in recent weeks. To date, we have found no evidence allowing us to attribute this threat and the motive behind the attack remains unknown.
More from The Record: Compared to more obvious methods like HTTP or HTTPS tunneling, this technique can be harder to detect because DNS traffic is generally considered benign and is often overlooked by security tools. Earlier in June, researchers discovered a campaign by suspected Chinese state-sponsored hackers, known as RedJuliett, targeting dozens of organizations in Taiwan, including universities, state agencies, electronics manufacturers, and religious organizations. Like many other Chinese threat actors, the group likely targeted vulnerabilities in internet-facing devices such as firewalls and enterprise VPNs for initial access because these devices often have limited visibility and security solutions, researchers said.

Long-time Slashdot reader UnderAttack explains: A blog post at the SANS Internet Storm Center suggests that OpenAI actions are being abused to scan for WordPress vulnerabilities.

Honeypot sensors at the Storm Center detected scans for URLs targeting WordPress that originated exclusively from OpenAI systems. The URLs requested all pages including the pattern '%%target%%', which may indicate that the scan is meant to include additional path components but the expansion of the template failed. The scans were not only identified by the unique user agent but also by the origin IP addresses matching addresses OpenAI published as being used for OpenAI actions. OpenAI actions allow OpenAI to connect to external APIs.
Johannes B. Ullrich, Ph.D. , Dean of Research, SANS.edu, wrote that OpenAI seems to be scanning random IP addresses — including honeypots.

One of Slashdot's most-visited stories of all time was the 2016 story asking: Can Cow Backpacks Reduce Global Methane Emissions? "Enteric fermentation," or livestock's digestive process, accounts for 22 percent of all U.S. methane emissions, and the manure they produce makes up eight percent more, according to the U.S. Environmental Protection Agency... Methane, like carbon, is a greenhouse gas, but methane's global warming impact per molecule is 25 times greater than carbon's, according to the EPA.
Cow methane still "heats the Earth more than every flight across the world combined," the Washington Post added today, reporting on a new $30 million genetic engineering experiment undertaken by the Innovative Genomics Institute and the University of California at Davis.

Its mission: to transform a cow's gut so it no longer releases methane. Using tools that snip and transfer DNA, researchers plan to genetically engineer microbes in the cow stomach to eliminate those emissions. If they succeed, they could wipe out the world's largest human-made source of methane and help change the trajectory of planetary warming... The average cow produces around 220 pounds of methane per year, or around half the emissions of an average car; cows are currently responsible for around 4 percent of global warming, according to the Food and Agriculture Organization...

Scientists envision a kind of probiotic pill, given to the cow at birth, that can transform its microbiome permanently...

The current project doesn't target only a particular cow species — it takes aim at the microbiome itself, offering a solution that could apply to all of them. Brad Ringeisen, executive director at the genomics institute, cut his teeth running biotechnology at the U.S. defense research agency DARPA, which helped pioneer transformative innovations including the internet, miniaturized GPS, stealth aircraft and the computer mouse. "I'm taking the DARPA mentality here," he said. "Let's solve it for all cows, not just a fraction of the cows." ...]

"There's no reason a cow has to produce methane," Ringeisen said. So what if scientists could just ... turn it off?
"I personally think this is the one that can make the biggest impact in the world," Ringeisen said. "Say you could wave a magic wand and eliminate all those emissions."

The article says that currently the scientists are feeding red-seaweed oil to a cow to measure the changes, to prepare for their final goal: "replicate those changes with gene editing." (They're using machine learning to reassemble the hundreds of pieces of each miccroorganism's DNA, so they can understand which changes they need to make with their early-intervention probiotic.) Such a probiotic could also improve a farm's productivity. Cows can lose up to 12 percent of their energy through burping up methane; other ruminants, like sheep and goats, also lose energy in this way. "If there is a way to redirect that hydrogen and convert it into milk, meat, wool — it would be much more accepted by farmers," said Ermias Kebreab [a professor of animal science at UC-Davis].

Early treatments will be tested on the cows at Davis, with researchers tracking their burps to evaluate the drop-off in methane emissions. There is still a long way to go. While scientists have proved that they can gene-edit microbes, researchers have so far only shown that they can edit a small fraction of the microbes in the cow gut — or the human gut, for that matter. Institute researchers are developing microbial gene-editing tools, even as they are mapping the species of the microbiome. They are building the plane while flying it.

The teams have received enough funding for seven years of research. The project started last year, and they hope to have a trial treatment ready for testing in cows in the next two years.

Six months after going public, Reddit "is winning over advertisers," reports Bloomberg, "by showing that it's different than other internet platforms, which often rely on users' identities and personal information to target ads." Instead, Reddit is targeting people based on their interests, relying on the site's [100,000+] deeply detailed communities — called subreddits — to match advertisers with potential customers... Early returns on that strategy have been promising. The text-based site easily surpassed expectations in its first two earnings reports this year, disclosing strong sales and better-than-expected projected growth. The stock is up 66% from its $34 initial public offering price in March.

Beyond targeting subreddits, the company also can use specific keywords to sell what it calls conversation ads. If a Redditor in r/HydroHomies — a community about the benefits of drinking water that has more than 1.2 million users — asks for advice about a specific brand of water bottle, an ad for that exact product could appear next to that user's post. These conversation ads are the fastest-growing ad format on the platform, the company said. They also give marketers a chance to appear in subreddits where customers are already talking about them...

Despite being around for close to 20 years, Reddit only started investing heavily in its advertising business in 2018, and is now hoping that marketers and investors are ready to acknowledge the site has grown up. Executives often point to its unique form of content moderation as proof that it's a safer place for brands than other sites. Reddit largely relies on a group of more than 60,000 human moderators — users who volunteer to serve as a sort of content police — to flag or take down unsavory content. On top of that, the site has a voting system so users can rate the quality of content. "From everything we're seeing, they have a level of brand safety and content safety for advertisers that is very comparable to most other social platforms," said Jack Johnston, senior social innovation director at performance marketing agency Tinuiti, which buys ads on Meta, Pinterest, X and Reddit. "That wasn't necessarily the case a couple years ago."

Those improvements have paid dividends. Reddit recently signed new content partnerships with major sports leagues, including the NFL, NBA and MLB, and the majority of Reddit's advertising revenue comes from Fortune 500 companies. Last year, the site made close to $800 million in ad sales, and counts marquee brands like Toyota, Disney, Samsung and Ulta Beauty among its advertisers. This year, analysts expect Reddit's overall advertising business to eclipse $1.1 billion in revenue and see the company reaching $2 billion in sales as soon as 2027, according to data compiled by Bloomberg. To get there, Reddit will need to court smaller marketers, too. The company makes more than 25% of its revenue from just 10 advertisers, meaning any unexpected pullback from a key partner could have a significant impact on the company's business, said Dan Salmon, lead analyst at New Street Research. "This army of small businesses — that's the most important thing for all of those platforms, for Reddit, for Pinterest, for X," he said...

Advertisers large and small say they're already planning to spend more on Reddit in the coming quarters.
The article points out that more than 90 million people visit Reddit each day.

Under the streets of New York City, they're testing a "quantum network," reports Phys.org — where engineers from a Brooklyn company named Qunnect Inc are taking steps to "overcome the fragility of entangled states in a fiber cable and ensure the efficiency of signal delivery." For their prototype network, the Qunnect researchers used a leased 34-kilometer-long fiber circuit they called the GothamQ loop. Using polarization-entangled photons, they operated the loop for 15 continuous days, achieving an uptime of 99.84% and a compensation fidelity of 99% for entangled photon pairs transmitted at a rate of about 20,000 per second. At a half-million entangled photon pairs per second, the fidelity was still nearly 90%...

They sent 1,324 nm polarization-entangled photon pairs in quantum superpositions through the fiber, one state with both polarizations horizontal and the other with both vertical — a two-qubit configuration more generally known as a Bell state. In such a superposition, the quantum mechanical photon pairs are in both states at the same time.
"While others have transmitted entangled photons before, there has been too much noise and polarization drift in the fiber environment for entanglement to survive," the article points out, "particularly in a long-term stable network." So the Qunnect team built "automated polarization compensation" devices to correct the polarization of the entangled pairs: In their design, an infrared photon [with a wavelength of 1,324 nanometers] is entangled with a near-infrared photon of 795 nanometers. The latter photon is compatible in wavelength and bandwidth with the rubidium atomic systems, such as are used in quantum memories and quantum processors. It was found that polarization drift was both wavelength- and time-dependent, requiring Qunnect to design and build equipment for active compensation at the same wavelengths...

Qunnect's GothamQ loop demonstration was especially noteworthy for its duration, the hands-off nature of the operation time, and its uptime percentage. It showed, they wrote, "progress toward a fully automated practical entanglement network" that would be required for a quantum internet.
And Qunnect's co-founder/chief science officer says "since we finished this work, we have already made all the parts rack-mounted, so they can be used everywhere..."

Their network design and results are published in PRX Quantum.

South Africa's telecoms industry body is pushing for digital content and service providers to help pay for the roll out of network infrastructure because they generate a huge part of the internet traffic. From a report: The Association of Comms and Technology (ACT) CEO Nomvuyiso Batyi said that the revenues generated by over-the-top (OTT) platforms and the continued success of the OTT model was dependent on the availability of high-quality, reliable and efficient network infrastructure. So "what we're saying is that the OTTs should contribute towards the network upgrades, the network building," she added. OTT platforms or services deliver digital content such as video, audio and messaging directly to consumers over the internet. "Fair share" arrangements ensure that OTT providers contribute to the costs of building, maintaining, and upgrading the infrastructure that supports their business.
