A school in Sheffield has banned the use of smart devices including phones and watches.

Forge Valley School no longer allows the use of smartphones, watches or headphones on its premises.

Any student found to be using them has to hand them in, with the gadgets not returned for 24 hours.

Head teacher Dale Barrowclough said children were previously left “zombie-like” as they were “glued to their mobile phones”.

One pupil said: “I’m finding myself speaking to a lot more people so I think it’s helpful.”

Artificial flavours released by cooking aim to improve lab-grown meat

Artificial flavours released by cooking aim to improve lab-grown meat

Cultured meat, with added flavour
Yonsei University

Lab-grown meat could get a flavour boost thanks to aromatic chemicals that activate when cooked, releasing a meaty smell – or if you prefer, that of coffee or potatoes.

Meat grown from cultured cells can already be created in various forms that resemble slaughtered meat, including steak and meatballs, but matching the taste has proven more challenging. Traditional meat flavours are extremely complex and volatile and don’t survive the lengthy laboratory process.

One key component of the taste of cooked meat is the Maillard reaction, named after a French chemist who discovered that unique flavours are created in cooked food at between 140 and 165°C (280 to 330 °F). Jinkee Hong at Yonsei University in Seoul, South Korea, and his colleagues say they have worked out a way to simulate the Maillard reaction by adding “switchable flavour compounds” (SFCs) into a 3D gelatine-based hydrogel, called a scaffold, that remain stable while the meat is cultured.

Once heated to 150°C, the chemicals “switch on” and release their flavours, improving the cultured protein’s palatability. “We actually smelled the meaty flavour upon heating the SFCs,” says Hong, though he wouldn’t confirm whether the team had actually eaten the meat.

These SFCs can also be used to create different flavour profiles. For example, the researchers tested three compounds and say they produced flavours simulating roasted meat, coffee, roasted nuts, onions and potatoes. “We can diversify and customise the flavour compounds released from the SFC,” says Hong.

One big issue is that the chemicals involved aren’t currently seen as safe for human consumption. “Because the materials and culture medium are not approved as edible materials, we cannot ensure the safety of it,” Hong says. “However, we think that our strategy can also be applied to conventional edible materials, which would be safer than the materials used in this study.”

Johannes le Coutre at the University of New South Wales in Sydney, Australia, says he is sceptical of the work for numerous reasons, including that the flavour tests predominantly used an electronic nose to assess the chemicals being released, rather than human judgement of whether they smelled appetising.

“You cannot nourish human beings with this type of material,” says le Coutre. “While cell-based meat is a promising technology concept, this particular way of adding flavour will never provide safe and sustainable protein for low and middle-income communities that need food.”

The US might blacklist the main iPhone SE 4 display supplier

Published

Apple has been trying to reduce the production cost of its iPhones for some time now. To achieve this, they have tried to turn to alternative suppliers for certain key components, such as displays. However, a new move by the US government could put Apple’s plans in jeopardy. A US representative requested that display suppliers from China, such as BOE and Tianma, be blacklisted. BOE would be the main OLED display supplier of the iPhone SE 4.

BOE is a Chinese display supplier that works with multiple big brands in the smartphone industry. Apple has been in talks with the company to use its panels in iPhone devices. According to reports, BOE has failed Apple’s quality tests for high-end iPhone displays, but the Cupertino giant would commission them to produce the majority of the iPhone SE 4’s displays.

US representative suggests blacklisting display suppliers from China

Apple may have to reconsider its plans regarding the displays of the next budget iPhone following a request from John Moolenaar, the Chairman of the House Select Committee on the Chinese Communist Party. Moolenaar requests the addition of BOE to the US trade blacklist in a letter to Defense Secretary Lloyd Austin. The letter also mentions Tianma Microelectronics, another Chinese display supplier.

The representative cites national security concerns as the main reason for the BOE’s potential blacklisting. The letter cites Chinese suppliers’ outsized market share growth in the LCD and OLED segment thanks to Chinese government funding. These suppliers have gone from 1% of the global OLED market share in 2014 to more than 52% today. They have also taken over 72% of the LCD market. Chinese suppliers have reportedly taken advantage of government funding to sell displays at cost, affecting competitors.

Previous reports suggested that BOE would manufacture 70% of the iPhone SE 4’s displays. Samsung was among the companies vying to supply the component. However, the deal fell through because Apple was willing to pay too little per unit. Indeed, reports suggest that Apple requested BOE to reduce the specifications of the “display candidate” to secure a lower price. There are no details on which specs would be reduced to save costs. However, we can imagine things like maximum brightness or resorting to older OLED technologies.

LG would be another candidate for the iPhone SE 4’s OLED screens

According to reports, Apple has also negotiated with LG to supply the displays for the iPhone SE 4. Reports suggest that the company is seeking to pay a maximum price of $40 per unit. The iPhone SE 4 would hit the market in 2025 for a price of $499. The possibility of a BOE blacklisting would force Apple to turn to more expensive suppliers, potentially increasing the estimated price for the next-generation budget iPhone.

VR hit Walkabout Mini Golf is getting a mobile edition

Walkabout Mini Golf has been filled with players ever since it launched around the same time as the Meta Quest 2. Now the multiplayer mini-golf game is making the jump to iOS devices.

The developer Mighty Coconut is currently beta testing its mobile mini-golf game and plans to release a full version on the App Store on October 10.

The Pocket version may be on mobile devices but the miniature version of the mini-golf game isn’t straying away from its virtual interface. The iOS Walkabout game can be played in two different modes: “Touch-to-Putt” mode in which you use the touch screen to tap and drag your shot and “Swing-to-Putt” mode in which you hold your iPhone like a putter and take your swing the same way you would in the VR version.

Walkabout Mini Golf is one of the most popular multiplayer VR games for the Meta Quest series. The virtual mini-golf game has an extensive series of stylized courses including some based on movies, TV shows and games like Jim Henson’s Labyrinth, the puzzle game Myst and the animated clay characters Wallace & Gromit. Mighty Coconut also designed a golf course with the immersive art company Meow Wolf and a series of courses based on the works of Jules Verne.
