Rêvez-vous de voler comme dans Spider-Man ? Un inventeur chinois a conçu son propre hoverboard volant et apprend à le piloter avec l’aide d’une intelligence artificielle. Mais derrière cette création, qui semble tout droit sortie d’un film de science-fiction, se cachent quelques limites.
Britain is funding the next generation of tech companies without making sure taxpayers get a slice of the action, MPs have warned. In a new report shared with The Register ahead of publication, the Public Accounts Committee (PAC) has accused UK Research and Innovation (UKRI) of being overly cautious about protecting taxpayers' interests. Rather than simply handing out grants, MPs want UKRI to consider taking equity stakes in more of the businesses it backs, giving the public a chance to cash in when those companies succeed. According to the Department for Science, Innovation and Technology (DSIT), UK universities produce more spinouts and patents per pound of research funding than their US counterparts. But Britain is less adept at cashing in on its inventions. British startups still struggle to attract the investment needed to grow without moving overseas, while universities have a patchy record when it comes to exploiting their intellectual property. UKRI, meanwhile, has been reluctant to impose tougher conditions on the research it funds, arguing that doing so could discourage companies from growing. “This approach is far too cautious and we urge the Department to do much more to recover taxpayer's money when a successful company exploits research which the taxpayer, via UKRI, has paid for," the PAC said. It wants UKRI to review its standard funding terms, including whether it should take equity stakes in more companies benefiting from public money. Sir Geoffrey Clifton-Brown, chair of the PAC, acknowledged that calling for the government to behave more like a venture capitalist might seem an odd position for a committee normally concerned with keeping public spending in check. "It may strike followers of this Committee's work that our call for government to take a less cautious approach to taking a direct stake in British innovation is an unusual one," he said. "But we are a body dedicated to value for taxpayers' money, not hoarding it. The nations currently leading the global tech race did not achieve their positions by avoiding more entrepreneurial policies. This is a simple case for the government of nothing ventured, nothing gained." The government has made some effort to help British tech firms. UKRI gives AI startups free access to taxpayer-funded supercomputers, while DSIT has changed its procurement rules to give UK companies a better shot at supplying £400 million worth of specialist AI chips. The British Business Bank is also investing alongside pension funds, giving taxpayers a stake in some of the businesses receiving support. But efforts to attract more pension fund investment have been slower than ministers hoped, and MPs want DSIT to start measuring whether its various support schemes are actually helping British companies grow, rather than simply counting how much money it hands out. There's also the question of where all that research funding ends up. London, the South East, and the East of England continue to receive half of UKRI's funding, despite years of government promises to spread investment more evenly across the country. The North's share has improved from 12 to 20 percent over the past five years, but UKRI has yet to set specific regional funding targets. Clifton-Brown described the divide as "continuing and unacceptable," warning that progress could easily be reversed without a more deliberate effort to spread the cash around. And while MPs want UKRI to be more adventurous with its investments, they're considerably less impressed with how it manages some of the projects already on its books. The committee pointed to an airborne laboratory upgrade that UKRI abandoned after spending £46 million of its £49 million budget. Funding was finally canceled five years after the decision to upgrade the aircraft, prompting MPs to question why the plug hadn't been pulled sooner. Elsewhere, around 45 percent of the Science and Technology Facilities Council's estate is in unacceptable condition, and restoring university-owned research infrastructure to full working order would cost an estimated £5.6 billion. The PAC also criticized UKRI for failing to ensure a replacement for the ARCHER2 national supercomputer would be ready before the existing machine shuts down, leaving an expected 13-month gap. It seems Whitehall has mastered the art of spending money on innovation, but getting any back is another matter. ®

iPhone Preview brings everyday PDF tasks into one built-in app, from rearranging pages to preparing a smaller attachment. Introduced with iOS 26, it remains available in iOS 27, whose user guide provides the instructions used here.
Apple’s Preview app can open PDFs directly, reorganize their pages, rotate or crop individual sheets, delete unwanted pages, insert new ones, complete forms, add signatures, protect documents with passwords and export smaller copies for sharing.
It can also scan paper documents directly into a PDF and combine multiple pages into one file.
That makes Preview surprisingly capable for common workflows such as signing a contract, cleaning up a scanned document, reducing an attachment before emailing it or rearranging pages in a report.
Start with the task your document requires. Rearranging pages, adding a signature and preparing an attachment are different from rewriting an existing paragraph or meeting a publisher’s production requirements. Preview’s documented tools cover many routine changes, while more specialized work may require a separate editor.

iPhone Preview Lets You Reorder, Delete and Crop PDF Pages
Page management is particularly useful for scanned documents. A report may contain a sideways sheet, an attachment in the wrong position or an empty page that needs removing before the file is shared.
Open a document in Preview and tap the page count to reveal its thumbnail view.
From there, a page can be moved simply by touching and holding its thumbnail and dragging it above or below another page.
That makes fixing a scanned contract or report straightforward when pages were captured in the wrong order.
To reorganize a document:
Preview > open PDF > tap page count > touch and hold a page thumbnail > drag it into position
The same thumbnail menu can delete a page entirely.
Touch and hold the unwanted thumbnail, then choose Delete Page.
Preview can also insert material into an existing document. The thumbnail menu offers options to add a blank page, import a PDF or image from Files, or scan additional paper pages with the iPhone camera.
That means a form missing one attachment can be repaired without recreating the complete PDF.
Rotation is equally direct.
Open the relevant page, tap the More button and choose Rotate Left or Rotate Right.
Cropping works on a page-by-page basis:
Preview > open PDF > select page > Crop > adjust the blue handles > Crop
This is particularly useful for scanned pages with oversized borders, desk surfaces or other material around the document.
Apple also provides Undo through the More menu, making these edits less intimidating when working on an original file. For documents that cannot easily be replaced, creating a duplicate first remains the safer approach.

Fill Forms, Add Signatures and Lock the Finished PDF
Preview also consolidates several document tasks that iPhone users may already recognize from Markup.
Fillable PDF forms can be completed directly inside the app. Text fields, checkboxes and other supported form elements can be selected and edited without converting the file into another format.
Signatures use Apple’s familiar Markup system.
Open the document’s signature controls and choose Add Signature. When using Markup, tap the Add (+) button first, then select Add Signature. Choose a saved signature or draw a new one with your finger; rotating the iPhone gives you more room.
A saved signature can then be positioned and resized on the document.
For recurring paperwork, that makes Preview useful for forms that arrive through Mail or Files and need to be returned quickly.
Preview > open PDF > Actions menu beside filename > Lock
Enter the same password in the Password and Verify fields, then confirm the change.
Apple automatically enables the password requirement when the file is locked.
This protection prevents someone without the password from opening the PDF normally and helps protect completed work from unauthorized access.
There is an important practical step before doing this: duplicate the document if you want to preserve an unprotected copy.
Preview > Actions menu > Duplicate
A password-protected PDF is only useful if the password itself can be recovered later. Losing it can make the document inaccessible, so the credential should be stored somewhere secure.
Preview Can Compress a PDF Before You Send It
Large PDFs are another problem Preview addresses without requiring a separate compression website.
Open the document, tap the Actions menu beside its filename and choose Export.
When PDF is selected as the output format, iOS 27 offers several options that can reduce file size.
Optimize Images for Screen lowers image resolution for documents intended primarily for display rather than high-quality printing.
Save Images as JPEG can reduce the size of embedded images further by using JPEG compression.
Two other export options serve different purposes. Create Linearized PDF optimizes a document for faster web loading, while Embed Text applies optical character recognition, or OCR, to make image-based content searchable.
Choose those options for loading behavior or searchability, rather than assuming they will produce the smallest attachment. For file-size reduction, the image optimization settings are the relevant controls.
The practical workflow for a smaller email attachment is:
Preview > open PDF > Actions menu > Export > PDF > Optimize Images for Screen > Save
Adding Save Images as JPEG can shrink image-heavy files further when maximum image fidelity is unnecessary.
These image-reduction options can sacrifice detail. Lowering resolution or using JPEG compression may affect small text, fine lines and photographs, so compare the exported copy with the original before sending it.
A document containing mostly text may shrink only modestly. A scan filled with high-resolution photographs can show a much larger reduction.
Preview also exports files into formats including HEIC, JPEG, PNG and TIFF when a PDF needs to become an image instead.
When exporting a PDF to an image format, resolution can be selected manually, giving users additional control over the balance between detail and file size.

Where Preview Still Falls Short of Adobe Acrobat
Reopen the exported file before sending it. Check the page order, orientation, completed fields and signature placement. Zoom in on small text and diagrams, especially if you reduced image resolution. The useful result is a document that remains readable and complete, not simply the smallest file you can create.
Keep the original under a different filename so you can produce another version if needed. A copy prepared for email may not be the best version for printing or archiving. Names such as “Application — Original” and “Application — Email Copy” help distinguish the files when they appear together in Recents.
If the task involves changing existing document text or satisfying a specific submission requirement, confirm that your chosen tool supports it before proceeding. For routine page organization, form completion and sharing, a checked Preview export may be all you need.
Britain's national digital ID scheme may be dead, but Whitehall appears to have forgotten to tell the infrastructure. Despite the government scrapping its controversial plans, officials told MPs on Monday that work continues on GOV.UK One Login, digital wallets, and a growing collection of digital credentials designed to help people prove who they are. The abandoned scheme was one of Keir Starmer's flagship policies, originally pitched as a compulsory digital ID card to crack down on illegal working. Privacy campaigners weren't impressed, warning of surveillance and government overreach, and ministers eventually made it voluntary before Andy Burnham, decided to bin the whole thing. But scrapping the scheme hasn't dented Whitehall's digital identity ambitions. Officials told MPs this week that more than 80 types of documents are earmarked for the government's digital wallet, including proof of benefits, driving test certificates, and Disclosure and Barring Service (DBS) certificates. That's quite a lot of paperwork for something that's supposedly dead. The revelations came during a Public Accounts Committee hearing on Monday, where MPs wanted to know what exactly had been scrapped. "But is it not the case, based on the answers you've given us this afternoon, that the infrastructure of digital ID in the public sector is still being pursued?" asked Sarah Green, Liberal Democrat MP for Chesham and Amersham. Susannah Storey, DCMS permanent secretary, was keen to draw a line between the national scheme ministers had scrapped and the digital identity projects Whitehall had no intention of abandoning. One Login already allows people to prove who they are online, she said, but "that is not the same as a national digital identity strategy." Rod Latham, DCMS director for cybersecurity and digital identity, had a convenient explanation for why so much of digital ID was still standing: the government had only scrapped plans for a new identity product. "We already had One Login and the Gov Wallet," he told MPs, adding that work on the digital identity trust framework was also underway before the national scheme was announced. Whitehall isn't wasting time putting that technology to use, with officials confirming that testing is already underway to enable digital credentials to work with private businesses. Natalie Jones, the senior responsible owner for GOV.UK One Login, revealed that the government had opened a testing environment for private sector providers to integrate with its digital wallet technology. This would let people use digital driving licenses to prove their age in pubs, collect parcels, or verify their identity online. "We've got a bit of a chicken and egg situation. A digital driving license is only useful if there are people ready and shops and businesses ready to receive it,” Jones said, noting that further testing is planned for December, with a national rollout of digital driving licenses targeted for 2027. MPs also pressed officials on privacy, particularly whether citizens would have to consent before their information was shared between government departments. "In the confines of digital ID used in digital services, then consent is the model," said Christine Bellamy, interim director general for digital products at the Government Digital Service. There's a catch, of course. Government departments can already share data without asking permission, and officials couldn't quite explain how that squares with their promises about consent. "The strategy needs to be fully finished," Bellamy admitted, which might not be the reassurance MPs were hoping for. Jones insisted that One Login was "not a big data lake," saying it stores identity information separately and cannot see what users do inside government services. "One Login does not issue a single identifier to people," she added. Rupert Lowe MP remained unconvinced, warning that Britain could end up getting digital ID "by the back door rather than the front door." Officials maintained that the canceled national scheme was fundamentally different from the services still being developed, and that people would retain alternatives to digital identification. National digital ID may be officially dead, but between One Login, digital wallets, and dozens of planned credentials, Whitehall still has plenty of identity-related work to keep it busy. ®

Nuevos hallazgos aportan una base anatómica para comprender cómo dos sistemas neuroquímicos de señalización, el de la dopamina y el del óxido nítrico, podrían interactuar en la regulación de la función sexual masculina y otras funciones neuroendocrinas. Investigadores de la Universidad de La Laguna han estudiado la relación entre ambos sistemas de señalización en el núcleo paraventricular del hipotálamo de la rata. Los resultados muestran que cerca del 45 % de las neuronas productoras de óxido nítrico también expresan receptores dopaminérgicos D1 o D2, lo que demuestra la interacción entre ambos sistemas a escala neuronal.
