– Tech giant: What is ByteDance, the TikTok parent in US crosshairs?

The app has been a diplomatic hot potato between the United States and China since the administration of former president Donald Trump, who once wanted to ban the app.

Now, a bill in Congress aims to force the company to cut ties with ByteDance or be barred from the United States.

The bill's supporters say ByteDance as a Chinese firm simply cannot go against the wishes of Beijing, and can provide access to the data on more than 170 million American users for everything from spying to election influence campaigns.

– TikTok's Security Threats Go Beyond the Scope of House Legislation

But that glosses over the deeper TikTok security problem, which the legislation does not fully address. In the four years this battle has gone on, it has become clear that the security threat posed by TikTok has far less to do with who owns it than it does with who writes the code and algorithms that make TikTok tick.

Those algorithms, which guide how TikTok watches its users and feeds them more of what they want, are the magic sauce of an app that 170 million Americans now have on their phones. That's half the country.

But TikTok doesn't own those algorithms; they are developed by engineers who work for its Chinese parent company, ByteDance, which assembles the code in great secrecy in its software labs, in Beijing, Singapore and Mountain View, Calif. But China has issued regulations that appear designed to require government review before any of ByteDance's algorithms could be licensed to outsiders. Few expect those licenses to be issued — meaning that selling TikTok to an American owner without the underlying code might be like selling a Ferrari without its famed engine.

https://newatlas.com/science/cows-low-cost-insulin-production/

A genetically modified cow has produced milk containing human insulin, according to a new study. The proof-of-concept achievement could be scaled up to, eventually, produce enough insulin to ensure availability and reduced cost for all diabetics requiring the life-maintaining drug.

Unable to rely on their own supply due to damaged pancreatic cells, type 1 diabetics need injectable insulin to live. As do some type 2 diabetics. The World Health Organization estimates that of those who require insulin, between 150 and 200 million people worldwide, only about half are being treated with it. Access to insulin remains inadequate in many low- and middle-income countries – and some high-income countries – and its cost and unavailability have been well-documented.

In a newly published study led by the Department of Animal Sciences in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois Urbana-Champaign and the Universidade de São Paulo, researchers say they may have developed a way of eliminating insulin scarcity and reducing its cost using cows. Yep, cows.

"Mother Nature designed the mammary gland as a factory to make protein really, really efficiently," said Matt Wheeler, corresponding author of the study. "We can take advantage of that system to produce a protein that can help hundreds of millions of people worldwide."

[...] In the current study, the researchers inserted a segment of human DNA coding for proinsulin into the cells of ten cow embryos implanted into the uteruses of regular Brazilian cows. The implantation resulted in the birth of one transgenic calf. The term 'transgenic' describes an organism that contains artificially introduced DNA from an unrelated organism. Here, the human DNA used was targeted for expression in milk-producing, that is, mammary tissue only. Of course, a cow's mammary gland is more commonly called an udder.
...
When the calf matured, she was given hormones to stimulate her first lactation. While the volume of milk was less than would ordinarily be produced, the researchers found that it contained human proinsulin and – surprisingly – insulin.

AI assistants have been widely available for a little more than a year, and they already have access to our most private thoughts and business secrets. People ask them about becoming pregnant or terminating or preventing pregnancy, consult them when considering a divorce, seek information about drug addiction, or ask for edits in emails containing proprietary trade secrets. The providers of these AI-powered chat services are keenly aware of the sensitivity of these discussions and take active steps—mainly in the form of encrypting them—to prevent potential snoops from reading other people's interactions.

But now, researchers have devised an attack that deciphers AI assistant responses with surprising accuracy. The technique exploits a side channel present in all of the major AI assistants, with the exception of Google Gemini.

[...] By carefully monitoring these sources, attackers can assemble enough information to recover encrypted keystrokes or encryption keys from CPUs, browser cookies from HTTPS traffic, or secrets from smartcards, The side channel used in this latest attack resides in tokens that AI assistants use when responding to a user query.

Engineers are hopeful that the veteran spacecraft Voyager 1 might have turned a corner after spending the last three months spouting gibberish at controllers.

On March 1, the Voyager team sent a command, dubbed a "poke," to get the probe's Flight Data System (FDS) to try some other sequences in its software in the hope of circumventing whatever had become corrupted.

Readers of a certain vintage will doubtless have memories of poke sheets for various 1980s games. Not that this hack ever used a poke to get infinite lives in Jet Set Willy, of course.

While Voyager 1's lifespan is not infinite, it has endured far longer than anticipated and might be about to dodge yet another bullet. On March 3, the mission team saw something different in the stream of data returned from the spacecraft, which had been unreadable since December.

An engineer with the Deep Space Network (DSN) was able to decode it, and by March 10, the team determined that it contained a complete memory dump from the FDS.

[...] The next step is to study the memory read-out and compare it to one transmitted before the problem arose. A solution to the issue could then be devised.

One of the original Voyager scientists, Garry Hunt, told The Register that engineers at JPL were determined to get communications with the stricken probe working again: "This requires both skills and patience with the long time between communication instructions and response."

Back when scientific publications came in paper form, libraries played a key role in ensuring that knowledge didn't disappear. Copies went out to so many libraries that any failure—a publisher going bankrupt, a library getting closed—wouldn't put us at risk of losing information. But, as with anything else, scientific content has gone digital, which has changed what's involved with preservation.

[...] The work was done by Martin Eve, a developer at Crossref. That's the organization that organizes the DOI system, which provides a permanent pointer toward digital documents, including almost every scientific publication. If updates are done properly, a DOI will always resolve to a document, even if that document gets shifted to a new URL.

But it also has a way of handling documents disappearing from their expected location, as might happen if a publisher went bankrupt. There is a set of what's called "dark archives" that the public doesn't have access to but should contain copies of anything that has had a DOI assigned. If anything goes wrong with a DOI, it should trigger the dark archives to open access and the DOI to update to point to the copy in the dark archive.

For that to work, however, copies of everything published must be in the archives. So Eve decided to check whether that's the case.

Boeing Paper Trail Goes Cold Over Door Plug Blowout

Arthur T Knackerbracket has processed the following story:

Boeing has come in for criticism from the US National Transportation Safety Board (NTSB) over documentation detailing who was responsible for failures in the Alaska Airlines Flight 1282 door plug attachment.

NTSB chair Jennifer Homendy spoke before the Senate Commerce Committee on March 6. Responding to a question from ranking member Senator Ted Cruz regarding cooperation from the parties involved in the incident, Homendy said: "Boeing has not provided us with the documents and information that we have requested numerous times over the past few months. Specifically with respect to opening, closing, and removal of the door and the team that does that work at the Renton facility."

[...] Investigations have since focused on the door plug and how it was fitted. A preliminary investigation found that the door plug had not been properly bolted into place following work to deal with damaged rivets at the edge of the door frame.

"Wow," said Cruz. "Are you telling us that even two months later, you still do not know who actually opened the door plug?"

"That's correct, Senator," replied Homendy. "We don't know, and it's not for lack of trying." Homendy acknowledged that it can take a while for all the paperwork to be forthcoming. "But for this one, it's two months later."

Homendy told the committee that despite inquiries, the NTSB had not received the names of the 25-member team handling the door plugs. It had also not received all the records regarding the work to deal with the door plug and was having to use email dates and photographs to work out the timeline.

"It's absurd that we don't have that," said Homendy.

The NYPD sent a sweeping subpoena seeking information from the social media account of the president of a New York City police accountability organization in February, records reviewed by Hell Gate show, only to withdraw its subpoena when told they would need to justify the subpoena in court.

Michael Clancy, better known to friends on and off social media as Rabbi, received a notice last month from X, formerly known as Twitter, alerting him to the fact that the NYPD had sent X a subpoena requesting "all records consisting but not limited to all subscriber name(s), Email address(s), Phone number(s), account creation date, IP logs with timestamps (IP address of account logins and logouts), all logs of previous messages sent and received." The subpoena also requested "all videos sent and received, including but not limited to meta-data. exit data about the messages and videos" for the account.

The notification included a copy of the subpoena, which warned X not to tell Clancy of its existence. "You are not to disclose or notify any customer or third party of the existence of this subpoena or that records were provided pursuant to this subpoena," the document read.

But X, following its own corporate policy, told Clancy anyway, and suggested he might want to get some legal representation to fight the subpoena, recommending the American Civil Liberties Union.

Banana Pi's low-cost router supports 2.5G+5G WiFi with LAN ports:

Banana Pi is now selling a fully built Wi-Fi 6 router with some solid features for just $30 excluding shipping via Ali Express. This router uses OpenWRT firmware and dual-core Arm A9 Processor-based Triductor TR6560 SoC with Triductor's TR5220 WiFi 6 chipset.

The company has been selling this WiFi 6 router board on its own, but now you can buy an out-of-box unit that contains an enclosure for the board with six external antennas, Ethernet cables, and a power adapter with either EU or US plugs. The only difference here is that one of the LAN ports is removed.

[...] The router supports the 802.11ax bandwidth protocol and provides WPA3 password protection. Power over Ethernet is optional and can be added via a module, but it needs to be soldered. Banana Pi's wiki page specifies that its 2.4G signal works up to 40 meters to provide 573.5 Mbps bandwidth and 5G works up to 160 meters up to 2,401.9 Mbps.

Read the specs here.

https://newatlas.com/energy/sand-battery-finland/

A new industrial-scale 'sand battery' has been announced for Finland, which packs 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be about 10 times bigger than a pilot plant that's been running since 2022.

The sand battery, developed by Polar Night Energy, is a clever concept. Basically, it's a big steel silo of sand (or a similar solid material) that's warmed up through a heat exchanger buried in the center, using excess electricity from the grid – say, that generated during a spike from renewable sources, when it's cheap.

That energy can then be stored for months at a time, with reportedly very little loss, before being extracted as heat on demand. This could theoretically be converted back into electricity, although with some energy loss. But Polar Night says that the most efficient method is to just use the heat itself.

In a chilly place like Finland, that means feeding it into the local district heating system, which shares heat produced from industry or energy production through the community. Networks of pipes carry this heat as hot water or steam to warm up houses, buildings, even swimming pools. In this case, the new sand battery would be trialed in the district heating system of the Finnish municipality of Pornainen, run by a company called Loviisan Lämpö.

This new sand battery is expected to stand 13 m (42.7 ft) tall and 15 m (49.2 ft) wide, providing an output power of 1 MW and a capacity of 100 MWh. That, the companies claim, equates to a week's worth of Pornainen's heat demands in winter, or a month's worth in summer. By comparison, Polar Night's previous sand battery stands 4 x 7 m (13 x 23 ft), for a nominal power rating of 100 kW and a capacity of 8 MWh.

Since Broadcom's $61 billion acquisition of VMware closed in November 2023, Broadcom has been charging ahead with major changes to the company's personnel and products. In December, Broadcom began laying off thousands of employees and stopped selling perpetually licensed versions of VMware products, pushing its customers toward more stable and lucrative software subscriptions instead. In January, it ended its partner programs, potentially disrupting sales and service for many users of its products.

This week, Broadcom is making a change that is smaller in scale but possibly more relevant for home users of its products: The free version of VMware's vSphere Hypervisor, also known as ESXi, is being discontinued.

ESXi is what is known as a "bare-metal hypervisor," lightweight software that runs directly on hardware without requiring a separate operating system layer in between. ESXi allows you to split a PC's physical resources (CPUs and CPU cores, RAM, storage, networking components, and so on) among multiple virtual machines. ESXi also supports passthrough for PCI, SATA, and USB accessories, allowing guest operating systems direct access to components like graphics cards and hard drives.

Reddit aims for $6.4bn valuation ahead of initial public offering:

Reddit, one of the most popular websites in the world, is hoping for a valuation of up to $6.4bn (£5bn) when its shares go public next week.

The social media company, which has never made a profit, will float shares on the New York Stock Exchange.

A filing in the US revealed that Reddit and its investors are hoping to sell 22 million shares for between $31 and $34 each.

However, many users worry the move will fundamentally change the website.

Some shares will be specially reserved for some Reddit users and moderators.

The company is planning an initial public offering (IPO) which would make some of its shares publicly available to buy for the first time.

"Our users have a deep sense of ownership over the communities they create on Reddit," wrote co-founder Steve Huffman in a letter to prospective investors released a few weeks ago.

"We want this sense of ownership to be reflected in real ownership - for our users to be our owners. Becoming a public company makes this possible."

Reddit, which was founded almost 20 years ago, is an online forum where users can post questions and comment on topics that interest them.

[...] However, some users are worried that the IPO would change the site for the worse.

"When the most important customers shift from [users] to shareholders, the product always [suffers]," said one person.

"It becomes 'what can we do this quarter to squeak out an additional point of revenue', instead of 'how can we make this product better'."

[Hmmm, a site built on user-submitted topics and user-submitted comments that has never made a profit might be worth $6B . . . maybe after the new site is set up we should IPO while the iron is still hot! --hubie]

https://newatlas.com/biology/tap-honeybee-colony/

Delivering a gentle automated tap to the outside of a hive and recording the honeybees' collective response can give an indication of the colony's health without having to look inside, new research has found.

At last check, there were an estimated 115,000 to 125,000 beekeepers in the US, most of whom were hobbyists. In particular, ownership of honeybee colonies appears to have risen in recent years, with amateur apiarists wanting to help preserve these powerful pollinators in addition to generating their own source of sweet, sticky goodness.

But caring for honeybees can be tricky. Colonies follow very specific activity patterns throughout the year; they should be very busy in warmer months and idle when it's cold. So, they need to be checked regularly for health and productivity. Beekeepers can inspect hives by opening them, but this invasive process risks harm to the colony, particularly the all-important queen.

A new study led by researchers from Nottingham Trent University in the UK suggests they have a solution: gauging health by gently tapping the hive and listening for the bees' collective response.

"It's a bit like a bear that falls asleep for the winter; sometimes, you cannot tell if the animal is alive or not," said Martin Bencsik, the study's lead and corresponding author. "A gentle tap, causing a tiny, but measurable reaction, will reveal whether the animal is in its normal state or not."

The researchers' 'gentle tap' was delivered at random times by an electromagnetic shaker attached to a hive's outer wall, driven by a computer that provided a 0.1-second pulse at 340 Hz. The honeybees' response was recorded by an accelerometer embedded in the middle of the hive's frame, which was sensitive to the insects' vibrations.
