'The nutritional value of fruit and vegetables has fallen by up to 50pc since the Sixties because of declining soil quality, according to a new study.
'The study found that many crops had lost 20pc to 50pc of several key nutrients.
'Will Summers, a senior associate at the firm, said: “For 60 years we’ve measured food security in calories and tonnes per hectare.
'“On those measures we’ve done remarkably well. But we’ve been quietly hollowing out what’s inside our food.”
'The decrease in nutrient and vitamin value is thought to be down to declining soil quality and crops being selectively bred for their ability to grow quickly, rather than there being any focus on their health benefits.'

Ezra Klein's recent interview with Bill Gates on the dangers of AI leaves a different impression from the current discussion on this topic. He addresses some of the usual questions — What about China?, plausible dangers, regulation vs. free market, the "jobpocalypse", etc., but with his more Gatesian figures-backed style of response.
One of Gates's perspectives is on providing foreign aid, an area in which he has been involved since stepping away from the helm of Microsoft. He addresses both AI, and the recent drop in contributions to foreign aid.
He is also questioned about Epstein, and his relationship with the man.

Financial journalist Bethany McLean ponders What Happens if the A.I. Bubble Bursts (NYT, alt. source) in a NY Times op-ed. McLean, whose earlier reporting on Enron (YouTube) led to the downfall of the company and its auditor Arthur Andersen, begins:
It was about a year ago that Sarah Friar, the chief financial officer of OpenAI, said one way the company might sustain its current financial high-wire act was with a “backstop” or “guarantee” — as in, a government guarantee — “that allows the financing to happen.” Almost at the same time, Sam Altman, the company’s chief executive, said, “Given the magnitude of what I expect A.I.’s economic impact to look like,” the government should serve the role of “insurer of last resort.” They qualified those comments, but still, the gist seemed to be that the industry The Wall Street Journal calls “the biggest economic bet in U.S. history” is so important to the nation that if it needs more funding, taxpayers should be on the hook. Another way to put it is that the government should regard artificial intelligence the same way it regarded the banks in the 2008 financial crisis: too big to fail.
It’s hard to reconcile that suggestion with the other message blaring out of leading A.I. companies these days: that the technology “could kill us all by the end of the decade,” as the former Anthropic researcher Jacob Coxon recently warned, and must therefore be restrained. A.I. is so important that we can’t let it fail, but so risky that we shouldn’t let it go forward? Now add the conventional wisdom that the United States has to beat China at all costs (or as President Trump put it, “Whoever wins A.I. wins!”), and the arguments can start to reinforce one another. The more the race to dominate becomes existential, the more we have to spend on it; the more we spend on the industry, the more economically and geopolitically consequential it becomes; the more consequential it becomes, the greater the need to speed ahead, safety concerns be damned; the more we race ahead heedless, the more risk there is. All in all, it raises an even scarier possibility: What if rather than being too big to fail, A.I. is too big to stop?
She concludes:
This technology may be critical to the future of the United States, but preserving it doesn’t mean we have to bail out the private entities that are leading the field at this particular moment, nor does it mean we have to protect the fortunes of their investors and executives. The solution to the whole ever-expanding A.I. terror starts with remembering the lessons of the 2008 crisis: No company should be too big to fail.

For years, students were told that learning to code was one of the safest paths into a lucrative technology career. New data suggests that message may be losing some of its pull. Nova Learning says the share of surveyed middle and high school students naming Computer Science and AI as their primary academic interest fell from 42.3 percent in 2025 to 27.9 percent in 2026, while Engineering rose from 11.9 percent to 23 percent. The biggest gains came from Mechanical and Aerospace Engineering, while Software and Data Science saw a steep drop.
The survey is not nationally representative, but broader enrollment data points in the same direction. The National Student Clearinghouse Research Center reported declines in Computer and Information Science enrollment at four year institutions, even as Engineering grew. AI coding tools are not proven to be the cause, but as software development changes and AI handles more coding tasks, students may be starting to rethink what a future in technology should look like.

Interesting Engineering is reporting that researchers at the University of Groningen in the Netherlands found that tin-based perovskite solar cells can slow heat loss from high-energy “hot electrons” by a factor of 1,000 and could push solar cell efficiency beyond the theoretical 33 percent limit.
When sunlight strikes a panel, photons jump-start electrons into action. The most energetic photons create super-charged hot electrons. Theoretically, these high-voltage powerhouses should generate far more electricity, but, in practice, they are fleeting. In fractions of a trillionth of a second, these high-energy particles rapidly cool, dumping their bonus energy as waste heat before ever leaving the solar cell.
“This means that the energy is lost before the hot electron exits the solar cell material,” said Jan Anton Koster, Professor of Physics of Novel Semiconductors and Devices at the University of Groningen.
Using a specialized solar cell material called tin-based perovskite, Loi’s lab performed a feat many thought impossible: she slowed the heat loss down by a factor of 1,000. Suddenly, the extra energy lingered for nanoseconds instead of vanishing in picoseconds.
The study findings were published in the journal ACS Energy Letters.

'Scientists have solved the mystery of when black holes “burp” – when the astronomical bodies launch jets after feeding on stars, blasting material enormous distances in space.
'Scientists know from rare observations of stars being torn apart by black holes – a process that involves a stretching effect known as “spaghettification” – that “only about half of the star that gets too close to the back hole will end up eventually being swallowed by that black hole”, Goodwin said.
'The other material is launched back into space in powerful jets and outflows, sometimes so large they “can influence the entire evolution of a galaxy”, she said. “You can think of it as a black hole burp.”'

Science Alert is reporting that Scientists have now demonstrated one of the weirdest forms of ice yet – under preposterous pressures up to 2.3 million atmospheres, and tremendous temperatures up to 2,630 kelvins (2,357 degrees Celsius, or 4,274 degrees Fahrenheit).
This superionic water ice is a deeply odd state of matter that's neither entirely solid nor entirely liquid. Its oxygen atoms remain fixed in a rigid crystal lattice, as they would in a solid. But the hydrogen nuclei are mobile, diffusing through that lattice more like particles in a liquid.
Researchers squeezed the samples between the tips of diamonds to pressures as high as 230 gigapascals, while using lasers to heat them to thousands of degrees. That's 2.3 million times Earth's atmospheric pressure at sea level – the pressure at the center of Earth, for context, is around 360 gigapascals.
Then, using an extremely narrow beam of synchrotron X-rays, they probed for changes in the crystal structure of the ice.
What emerged was a configuration predicted theoretically but never unambiguously observed in experiments: hexagonal close-packed, or hcp, ice. As the hcp crystal was heated, its expansion also showed a signature of superionic behavior, suggesting it entered the superionic state at around 1,700 kelvins.
Superionic ice is thought to exist deep inside Uranus and Neptune, where its unusual properties may play a role in generating the planets' equally unusual magnetic fields.
The findings have been published in Physical Review Letters: Observation of Hexagonal Close-Packed Water Ice at Conditions in Ice Giant Planetary Interiors

Quantum computers harness the power of quantum mechanics, the laws that govern physics at atomic and subatomic scales. Among various designs for such machines, Helios is a trapped-ion quantum computer, which means it uses charged atoms suspended in free space using electromagnetic fields.
It operates using 98 qubitsâ"the units of information that a quantum computer uses to process data. This number of qubits makes it the largest trapped-ion quantum computer built so far. Quantinuum, the company behind the device, is based in Cambridge, U.K., and Broomfield, Colorado. It demonstrated earlier machines operating on 32 qubits in 2023 and 56 qubits in 2025.
Helios and its predecessors use an architecture (or operational structure) with separate regions for storing and processing quantum information. The architecture is called a QCCD (quantum charge-coupled device) and was invented in 2002. This is akin to the architecture of classical computers that have memory for storage (hard disk drives, solid-state drives) and a separate processor (CPU, GPU).
The specific geometry of Helios resembles a rosette, with a ring for storage and two streamers for processing. The crucial element is the four-way X junction where they meet. A QCCD physically transports the charged objects (the ions) electrically from the storage to the processing regions.
The processing is done using laser pulses. This requires a quantum algorithm to be broken up into ion transport and quantum processing. This differs substantially from other quantum computing architectures, such as superconducting qubits, where the qubits are fixed in space and processing is executed by electrical signals switched on and off in time.

Mark Zuckerberg has faced questions over why a small cruise ship in south-east Alaska rescued a stranded skiff and its crew when his 387ft superyacht had been closer.
The Silicon Valley billionaire’s yacht, worth a reported $300m, is said to have “repeatedly” declined to assist when a nearby boat called for help last week.
Zuckerberg, CEO of Facebook and Instagram owner Meta Platforms, was not on board at the time, a spokesperson told Forbes.
When a nearby 21ft skiff ran out of fuel between Petersburg and Juneau, the Alaska Beacon reported operators of a cruise ship that was further away than Zuckerberg’s yacht came to the rescue.
“I’m on a small-ship Alaska cruise with my son,” a passenger on the UnCruise Adventures ship Wilderness Legacy posted on Bluesky.
“Our boat rescued a stranded vessel last night and apparently we did that after the Coast Guard radioed Mark Zuckerberg’s yacht – which was closer – and they repeatedly refused to respond. (There was near unanimous booing when the captain announced this).”

A service called ISBNdb facilitates orders of up to a million books and keeps buyers anonymous. Pre-2022 books are premium because they're free of AI-generated text. A federal judge ruled the practice is fair use because eliminating the original means only one copy exists at a time. Anthropic hired the former head of Google Books partnerships to obtain "all the books in the world."
This is irreversible. You can re-upload a website. You can reprint a bestseller. You can't replace the last three copies of an 18th-century botanical text once someone shreds them for training data. And the judge said it's legal. So it's going to accelerate.
"We shred rare books and offer NDAs so nobody finds out" is a legitimate business model in 2026.

For a handful of very specific engineering problems, one can specify hard requirements. One might ask, for instance: how many sensors, how much CPU and GPU power, and how many lines of code does an autonomous vehicle need in order to drive more safely than a human driver in 99.99 percent of cases?
But for the vast majority of software, there is no such fixed number. We can simply add more and more features to make software more convenient for users and to add functions that no one ever thought possible in the past. This elasticity of demand — the economist’s term for how much more of something people want when it becomes cheaper — is the key to understanding why AI-assisted programming is unlikely to eliminate programming jobs.
Much of the programming world, particularly web development, is centered around the United States, where shareholder value is the legally and culturally dominant corporate priority. The influential investor class, dominated by the wealthier segments of the baby boomer generation, has been told by AI company CEOs that large language models can replace software engineers. These investors expect technology companies to demonstrate commitment to AI by reducing their engineering headcount, regardless of whether such reductions make technical sense.

Being a titan in the history of physics, the 1918 Nobel Laureate in Physics, having the smallest rational physical measurement (the Planck Length) named after you, and being deceased for 79 years is all apparently still not enough to prevent your work from being threshed and hit with retractions by an algorithm. Science.org has a succinct article that explains it:
"In early May, Yves Gingras, a historian of physics at the University of Quebec (UQ) at Montreal, was browsing Retraction Watch, a website that catalogs fraud, data manipulation, and other scientific sins. He noticed a link that read, “Retractions by Nobel Prize winners.” Were there really Nobel laureates whose papers had been withdrawn from the scientific literature?
After clicking, Gingras froze. “That’s impossible,” he recalls thinking. The fourth name on the list, with two retracted papers, was Max Planck—a legendary pioneer of quantum mechanics and the 1918 Nobel laureate in physics. Gingras had never heard a whiff of scandal about Planck, who was almost as widely revered for his character as his physics. In 1933, for example, he bravely confronted Adolf Hitler over Nazi Germany’s discriminatory laws against Jews."
The Springer Nature, the current-day owner of the journal Naturwissenschaften in which the papers were published 86 years ago, appears to have set an algorithm loose on their library, hunting for plagiarism and other reasons to retract papers... and failed to tell it to leave historic cornerstone works and authors alone.
"The retraction of the second Planck paper, published in 1940, left Gingras and Khelfaoui even more baffled. It also cited copyright violation—yet the piece had never appeared elsewhere. Then Khelfaoui noticed something that added to suspicions that an algorithm was at work. [...] In November 1940, philosopher Aloys Müller criticized Planck’s views in a Naturwissenschaften piece titled “Naturwissenschaft und reale Außenwelt” (“Natural Science and the Real External World”). A month later, Planck responded in print—and used the exact same title. This, Gingras and Khelfaoui suspect, caused Springer Nature’s copyright bot to retract the paper as plagiarism decades later, even though the contents of the two essays differ markedly."
However, apparently feeling like they had to retract the paper was not enough to fully dissuade Springer Nature from still selling it, in its retracted form:
"Gingras was especially incensed that Springer Nature deviated from the normal practice of merely slapping the word RETRACTED across the digital version of the paper while still allowing scholars to read the text. Instead, the publisher posted a blank white page with the cryptic phrase, “This article has been withdrawn due to article violation.” Springer Nature is nevertheless still selling the empty PDF for $39.95."

The heavily promoted, $499 T1 "Trump Phone" was originally said to be "Made in the USA" and ship in September 2025. Later, that was downgraded to "Assembled in the USA". Given the Trump Organization's lack of engineering or supply chain expertise, many assumed the "T1" would just be a private-label phone made by someone else. After a number of delays, the first phones are finally shipping.
iFixit has performed a teardown and concluded that the T1 is a just gold-painted 2024 HTC U24 Pro — a device from a Taiwanese company, probably using mainland China design and supply chains. In collaboration with NBC News, the iFixit team examined both phones using CT scans, side-by-side teardowns, and even reassembled a working T1 using a U24 Pro main board. As for "assembled in the USA", that may be true, in the same sense that your phone's repairman can "assemble" a phone from a handful of subassemblies sourced from someone else. Or it may have been assembled in Guangdong, China like the other U24 Pros.
iFixit sums it up: "What you have is not an 'American-Proud Design', but a phone designed in China, made in China, with the vast majority of parts sourced from China. I’m failing to find any stirring of American pride within me. I’ve certainly felt it before, so I can confirm that it is absent at this time."
