Submission + - The sweetpotato's DNA turned out stranger than anyone expected (sciencedaily.com)

alternative_right writes: The research revealed surprising complexity. The sweetpotato genome is a mosaic assembled from multiple wild ancestors, some of which have yet to be identified. About one-third comes from Ipomoea aequatoriensis, a wild species found in Ecuador that appears to be a direct descendant of a sweetpotato progenitor. Another significant portion resembles a wild Central American species called Ipomoea batatas 4x, though the actual donor may still remain undiscovered in the wild.

"Unlike what we see in wheat, where ancestral contributions can be found in distinct genome sections," says Shan Wu, the study's first author, "in sweetpotato, the ancestral sequences are intertwined on the same chromosomes, creating a unique genomic architecture."

This intertwined genetic heritage means that sweetpotato can be tentatively classified as a "segmental allopolyploid" — essentially a hybrid that arose from different species but behaves genetically as if it came from a single one. This genomic merging and recombination gives sweetpotato its remarkable adaptability and disease resistance, traits crucial for subsistence farmers worldwide.

Submission + - Synthetic magnetic fields steer light on a chip for faster communications (phys.org)

alternative_right writes: The team achieved this by systematically altering the symmetry of tiny repeating units in silicon photonic crystals. Adjusting the degree of local asymmetry at each point allowed them to "design" pseudomagnetic fields with tailored spatial patterns, without breaking fundamental time-reversal symmetry. Both theoretical analysis and experiments confirmed that these engineered fields can guide and manipulate light in versatile ways.

To demonstrate practical applications, the researchers built two devices commonly used in integrated optics. One was a compact S-shaped waveguide bend that transmitted light with less than 1.83 decibels of signal loss. The other was a power splitter that divided light into two equal paths with low excess loss and minimal imbalance.

In a final test, the devices successfully transmitted a high-speed data stream at 140 gigabits per second using a standard telecommunications modulation format, showing that the technique is compatible with existing optical communication systems.

Submission + - From the 'Banter Bill' to Bias Hotlines: The Alarming Rise of Snitch Networks. (thedailyeconomy.org)

An anonymous reader writes:

A troubling new piece of legislation continues to make its way through the British parliament. Dubbed the “Banter Bill,” the Employment Rights Bill would criminalize any speech that might be considered offensive by any passerby.

As Dominic Green reports for The Free Press, under this proposed law, “Britons can be prosecuted for a remark that a worker in a public space overhears and finds insulting.” Under this standard, whether a certain sentiment (for instance, that Britain should reduce immigration) is legal will now depend on whether someone in the vicinity takes offense.

Unfortunately, this new subjective standard for what types of speech are allowed isn’t restricted to Great Britain. In the United States, more and more states are experimenting with a similar system. The Washington Free Beacon reports that eight states have set up “bias-response hotlines” which citizens are encouraged to call if they hear a comment — from a neighbor, coworker, or even passersby on the street — that they consider to be offensive. As Oregon says of their hotline, if you see or hear someone “creating racist images/drawings; mocking someone with a disability; or telling or sharing offensive ‘jokes’ about someone’s identity” they want to hear about it.

"The Lives of Others" was not supposed to be a training film.

Submission + - Imgur, an image sharing website, community revolts against Medialab (imgur.com) 2

karolgajewski writes: Over the past little while, Medialabs has enshittified their latest acquisition, Imgur, to the point where the community has revolted. Overwhelming ads some with sound, have made the site more annoying to use, the notification system has failed to notify users of responses to comments, and so on. The straw that broke the community's back was heavy handed censorship of anything critical of Medialabs. This led to a user revolt using a John Oliver meme with middle fingers that is currently overwhelmingly being posted by imgurians.

It's bad enough that I might use a process server to cancel membership. That way if the company goes "you didn't cancel", the process server will testify that they delivered the paperwork to a responsible employee, what the paperwork was, etc...

What paperwork will be delivered to a responsible employee? if you tell the payment processor to stop payment, thats all they do, they stop the payment. At least thats my experience in the USA.

This sums up my experience too. I used to be able to ask for it to play a song, and it'd find it on youtube. Now unless you subscribe to Youtube Music, its unable to even understand what you asked for, it usually plays something random it found that matches a single word of the song I asked for. Besides the inability to play music. It also has the habit of speaking up even though no one mentions "google". Whenever I find the time, I'm planning to remove it, it really only tells me the time or starts a timer for me.

Submission + - Recreating a Rare Mutation Could Grant Almost Universal Virus Immunity For Days (sciencealert.com)

alternative_right writes: The mutation, a deficiency in interferon-stimulated gene 15 (ISG15), causes a mild yet persistent inflammation across the body. Examining patients' immune cells revealed they'd had the usual run of encounters with flu, measles, chickenpox, and mumps, yet they'd never reported feeling particularly ill as a result.

Further investigation revealed their body's virus-fighting proteins were constantly on a low level alert, never really put away for later like in most people.

Submission + - Oklahoma will require teachers from NY, CA to prove they back 'America First' (usatoday.com) 1

fahrbot-bot writes: Teachers from California and New York who want to work in Oklahoma public schools will be required to pass a certification test to prove they share the state's conservative political values.

Regardless of the subject or grade they teach, they'll have to show they know "the biological differences between females and males" and that they agree with the state's American history standards, which includes elements of a conspiracy theory that the Democratic Party stole the 2020 presidential election from President Donald Trump, which fact checkers have said are false.

The state Department of Education will implement the new certification test for teachers from the two largest Democrat-led states "who are teaching things that are antithetical to our standards" to ensure newcomers "are not coming into our classrooms and indoctrinating kids," Oklahoma schools Superintendent Ryan Walters, said in an interview with USA TODAY. [Oblivious to the obvious irony.]

Walters has dubbed the new requirement an "America First" certification, in reference to one of Trump's political slogans. Nonprofit conservative media company Prager U is helping Oklahoma's state department of education develop the test.
