Deliveroo founder Will Shu to step down as CEO after DoorDash takeover

LONDON — Deliveroo CEO Will Shu is set to step down from the food delivery company he co-founded over a decade ago. Shu, who established Deliveroo in 2013 with childhood friend Greg Orlowski, said Thursday that he will step down as CEO after its takeover by U.S. rival DoorDash is completed. DoorDash announced its deal to buy the British online takeout platform in May. The acquisition values Deliveroo at £2.9 billion ($4 billion). "I have decided that now is the right time for me to step down,

ICEBlock handled my vulnerability report in the worst possible way

Last week, I wrote about how Joshua Aaron's ICEBlock app, which allows people to anonymously report ICE sightings within a 5-mile radius, is – unfortunately, and despite apparent good intentions – activism theater. This was based on Joshua's talk at HOPE where he made it clear that he isn't taking the advice of local community groups, that ICE sightings aren't verified in any way, and that he doesn't know what he's doing when it comes to security and privacy. In that post, in the section about

Unfortunately, the ICEBlock app is activism theater

At this summer's HOPE conference, Joshua Aaron spoke about ICEBlock, his iPhone app that allows users to anonymously report ICE sightings within a 5 mile radius, and to get notifications when others report ICE sightings near them. You can see the full talk, and the lively/infuriating Q&A, here, starting at 6:12:10. Thanks to repression from the highest levels of the Trump administration, his app has gone viral and garnered over a million downloads from the App Store. Karoline Leavitt called it

The Space Shuttle Columbia disaster and the over-reliance on PowerPoint (2019)

We’ve all sat in those presentations. A speaker with a stream of slides full of text, monotonously reading them off as we read along. We’re so used to it we expect it. We accept it. We even consider it ‘learning’. As an educator I push against ‘death by PowerPoint’ and I'm fascinated with how we can improve the way we present and teach. The fact is we know that PowerPoint kills. Most often the only victims are our audience’s inspiration and interest. This, however, is the story of a PowerPoint s

Death by PowerPoint: the slide that killed seven people

With Starship, SpaceX encounters an obstacle that haunted NASA’s space shuttles

Eventually, SpaceX wants to catch ships coming back from space with big mechanical arms on the launch pad, similar to the way SpaceX has shown it can recover the rocket's huge Super Heavy booster. This would allow SpaceX to theoretically stack a freshly flown ship on top of a booster right on the launch pad, then quickly refuel it and launch it again. There are plenty of things SpaceX must prove before the company is able to do this. But SpaceX has already demonstrated it can handle some of the

Physics of badminton's new killer spin serve

Serious badminton players are constantly exploring different techniques to give them an edge over opponents. One of the latest innovations is the spin serve, a devastatingly effective method in which a player adds a pre-spin just before the racket contacts the shuttlecock (aka the birdie). It's so effective—some have called it "impossible to return"—that the Badminton World Federation (BWF) banned the spin serve in 2023, at least until after the 2024 Paralympic Games in Paris. The sanction wasn

NASA Approves Ted Cruz’s Plan to Move a Space Shuttle to Houston, Setting Up a Fight With the Smithsonian

NASA has selected a yet-to-be-named Space Shuttle to move to Houston, conceding to a long-running bid by Texas senators to house one of the iconic vehicles. If the chosen vehicle is Discovery—which it likely is—the Smithsonian, which houses the vehicle, may put up a fight. The Trump administration included the shuttle’s relocation in the budget reconciliation bill, signed it into law on July 4, and set aside $85 million for the move and construction of a new facility in Houston. At the time, Te

RIP Shunsaku Tamiya, the man who made plastic model kits a global obsession

Shunsaku Tamiya, former president and chairman of Tamiya, Inc., passed away on July 18. His death was announced on July 21, with funeral services attended by close family and friends. Mr Tamiya led the transformation of Tamiya into a world-renowned manufacturer of high-precision plastic model kits, radio control vehicles, and motorized Mini 4WD racers. He joined the company founded by his father originally as a transport firm, and switched to supplying lumber after the war. That brought about

A Creepy Corn Maze Awaits at the ‘Clown in a Cornfield’ Activation

Clown in a Cornfield is a million-dollar title—so eerie, so evocative, and so perfectly descriptive of Eli Craig‘s horror movie, which hit theaters earlier this year. It’s headed to Shudder and AMC+ August 8, but even if you’ve been waiting to catch it on streaming, there’s much to scream about with its San Diego Comic-Con immersive experience. Why? Well, for one thing, it’s a haunted corn maze—and even though it’s indoors, it’s still dark and spooky as you’d expect. The queue drops you right i

Lyft to add autonomous shuttles in 2026 as Uber inks more self-driving deals

Lyft will add autonomous shuttles made by Austrian manufacturer Benteler Group to its network in late 2026, the company announced Friday. The shuttles will be deployed in partnership with U.S. cities and airports, according to Lyft, but could expand out from there if things go well. The partnership will let Lyft use urban electric shuttles made by Benteler’s mobility division under the Holon brand. The shuttles will not have a steering wheel or pedals and will feature inward-facing seats for up

Gupshup raises $60M in equity and debt, leaves unicorn status hanging

Gupshup, a business messaging startup that began its journey in India over two decades ago and became a unicorn four years ago, has raised a new over $60 million round — but is keeping its new valuation under wraps. In 2021, Gupshup raised two funding rounds within four months, securing $340 million from prominent investors including Tiger Global, Fidelity Management, Think Investments, and Malabar Investments. These rounds — the startup’s first in roughly a decade — valued Gupshup at $1.4 bill

“It’s a heist”: Senator calls out Texas for trying to steal shuttle from Smithsonian

A political effort to remove space shuttle Discovery from the Smithsonian and place it on display in Texas encountered some pushback on Thursday, as a US senator questioned the expense of carrying out what he described as a theft. "This is not a transfer. It's a heist," said Sen. Dick Durbin (D-Ill.) during a budget markup hearing before the Senate Appropriations Committee. "A heist by Texas because they lost a competition 12 years ago." In April, Republican Sens. John Cornyn and Ted Cruz, bot

Life after two-stroke: Rotax electrifies its bike and kart powertrains

Rotax provided flights from San Francisco to Salz, Austria, and accommodation so Ars could visit its factory and ride some of its products. Ars does not accept paid editorial content. "There was always a passion about motorbikes. But it's not only passion, it also needs to be a sustainable business model," Mario Gebetshuber, BRP-Rotax vice president of global sourcing and operations powertrain, told Ars Technica during a tour of the company's museum of motors over the decades. Gebetshuber says

Ted Cruz’s Bid to Reclaim Space Shuttle Discovery Could Cost $400 Million

At a time when money is too tight for NASA’s science exploration endeavors, Texas senators are willing to pour millions into a risky process to relocate the Space Shuttle to Houston under the so-called One Big Beautiful Bill. President Donald Trump’s tax and spending bill, which passed the Senate on Tuesday, includes a provision to move the Space Shuttle Discovery from the Smithsonian’s Air and Space Museum in Virginia to Space Center Houston. The Bring the Space Shuttle Home Act was added to t

Rocket Engines That Flew 22 Space Shuttle Missions Are Ready for NASA’s Next Moon Mission

NASA’s Space Launch System (SLS) is ready to fly with its four shuttle-era engines. The rocket, outfitted with the RS-25 engines, recently passed a critical milestone that put the integrated system to the test, using a decades-old design on a new launch vehicle. NASA teams successfully completed the RS-25 engine checkout tests at the Kennedy Space Center in Florida, ensuring seamless communication between the SLS core stage and its engines ahead of the first crewed mission to the lunar environm

Former SpaceX manager alleges harassment, retaliation, and security violations in lawsuit

A former SpaceX security manager, who was privy to top secret information on U.S. government programs, is suing the company and one of its senior employees for alleged discrimination, sexual harassment, and retaliation. Jenna Shumway, who was promoted to senior contractor program security officer after being hired in 2022, also alleges the senior employee — Daniel Collins, a former Defense Department official hired to run security compliance for the company’s government work — violated top secr

The Expanse: Osiris Reborn Will Take Cues From Mass Effect, Souls Games and More

For a certain kind of science fiction fan, the surprise news of a video game set in one of the most beloved TV and book series, The Expanse, hit like a freight train of hype. The Expanse: Osiris Reborn is an action RPG currently in development from Owlcat Games with no release date yet, but that hasn't stopped the studio's creative director, Alexander Mishulin, from giving me some early details about the game. There are many reasons The Expanse has been so successful, the largest of which is it

Best Heated Blankets of 2025

Nothing beats getting cozy under a heated blanket -- whether watching TV, working from home or curling up in bed. A regular blanket provides some warmth, but when temperatures drop, nothing matches the cozy comfort of a heated blanket. If you've been thinking about upgrading, now is the time. Plus, getting one now will also have you prepped and ready when winter rolls back around. What to look for in a heated blanket After you've scoured the internet for electric blankets, there are a few thin

Iran’s Internet Blackout Adds New Dangers for Civilians Amid Israeli Bombings

Alimardani says that it appears mobile data services are patchy, and for many people virtual private networks, which can be used to avoid censorship, have stopped working. This means it has been difficult to reach people in the country and potentially for information to get out, Alimardani says. “Some family that left Tehran today were offline and disconnected from the internet and finally found some connectivity when they were 200 kilometers outside of Tehran in another province,” Alimardani ex

Researchers teach robot to play badminton using Nvidia RTX machine learning

Why it matters: Ever since Boston Dynamics first showcased its famous legged robots in 2013, numerous organizations have introduced machines that autonomously perform various professional and recreational activities. The latest research utilizes badminton to develop a robot's agility and coordination, which could help advance training methods and maneuverability. Scientists at ETH Zürich recently published a study and video (below) explaining how they trained a quadrupedal robot to play badmint

India’s ‘Human Calculator Kid’ Shatters 6 World Records in a Single Day

Remember when your teachers used to say that mental math is important because you can’t walk around with a calculator everywhere you go? Never minding the fact that we now do, actually, take a calculator everywhere we go (hello, smartphones), a teenager from India has taken it a step further: He has essentially become a human calculator. Fourteen-year-old Aaryan Shukla cruised through six mental math calculation world records in a single day, according to a Guinness World Records statement publ

Amazon shuts down Chime, its Zoom alternative

In Brief Amazon Chime, the tech giant’s underwhelming alternative to Zoom and Google Meet, is shutting down for good. The company on Wednesday confirmed it will end support for Chime, including its Business Calling features, on February 20, 2026. As part of this transition, Amazon stopped accepting new Chime accounts as of February 19, 2025.
