The natural diamond industry is getting rocked. Thank the lab-grown variety

When Aret Oymakas started selling diamonds years ago, engagement ring shoppers came in looking for one thing for their brides-to-be: a real, mined diamond. "It was just a diamond," said Oymakas, owner of Livia Diamonds in Toronto. "And you got what you were able to get … in terms of design and budget." These days, not so much. Lab-grown diamonds have become massively popular in recent years, giving the traditional, mined version a run for its money. Oymakas says natural diamonds made up 100

Arvo Pärt at 90

In many ways Arvo Pärt and John Williams’s music couldn’t be further apart. One celebrates simplicity, purity, and draws much of its inspiration from sacred texts; the other captures strong emotions in sweeping orchestral scores. And yet the two men are today’s most performed contemporary composers. Bachtrack’s annual survey of classical music performed across the world placed Pärt second (John Williams is in the top spot) in 2023 and 2024. In 2022, Pärt was first, Williams second. This year, Pä

The Sail instruction-set semantics specification language

Implicit parameters are always integers, and they must appear first before any other parameters in the function type signature. The first argument can then just be omitted when calling the function, like so: Functions may also have implicit parameters, e.g. we can implement a zero extension function that implicitly picks up its result length from the calling context as follows: Sail will also ensure that the output of our function has precisely the length bits('n * 'm) for all possible inputs

Tesla investors are growing wary of Elon Musk's futuristic promises

Tesla CEO Elon Musk speaks alongside U.S. President Donald Trump to reporters in the Oval Office of the White House on May 30, 2025 in Washington, DC. At Tesla , vehicle sales are slumping, profits are thinning and revenue from regulatory credit sales are poised to dry up due to Republican-led policy changes. In the past, CEO Elon Musk's futuristic promises have convinced investors to look past top and bottom line numbers. Not now. Following another fairly dismal earnings report this week, M

Bonkers NASA Mission Aims to Drop Six Helicopters Onto Mars From Space

Defense tech company AeroVironment and NASA's Jet Propulsion Laboratory have shown off a wild concept for deploying six helicopters above the surface of Mars to scout for water and possible human landing sites. The concept, dubbed "Skyfall," builds on NASA's extremely successful and revolutionary Ingenuity Mars helicopter, which became the first manmade object to achieve powered flight on another planet in 2021. It flew a whopping 72 times over three years, vastly exceeding expectations. AeroV

If you have 90 minutes to spare, play the cyberpunk horror game s.p.l.i.t

s.p.l.i.t is the most badass typing game I’ve ever played. It’s actually more of a hacking simulator, cyberpunk thriller and puzzle experience than a typing game, but its core loop is bookended by sequences of high-intensity letter pecking with gruesome consequences — think Mavis Beacon as designed by Ted Kaczynski — and the final scenes have a way of searing themselves into your psyche. Not to mention, the whole thing takes place on a keyboard, no mouse or gamepad. So I guess it’s technically o

Ageing accelerates around age 50 ― some organs faster than others

Ageing of many tissues accelerates around age 50, according to an analysis of tissues in people ranging from teenagers to individuals in their sixties.Credit: Karen Haibara/AFP/Getty It is a warning that middle-aged people have long offered the young: ageing is not a smooth process. Now, an exhaustive analysis of how proteins change over time in different organs backs up that idea, finding that people experience an inflection point at around 50 years old, after which ageing seems to accelerate.

The rise and fall of the Hanseatic League

Today, we typically think of coalitions in the context of modern electoral politics. So it might be surprising that one of the greatest case studies in the history of coalitions is a community of medieval German merchants known as the Hansa. Starting as individual traveling traders, the Hansa built up coalitions for collective bargaining, collective action, and collective security. Through this process, they formed Northern Europe’s first ever long-distance trade network. Without corporate str

Floods and Other Disasters Kill More People at Night, but Not for the Reasons You Think

It was 4 a.m. on July 4 at Camp La Junta in Kerr County when Kolton Taylor woke up to the sound of screaming. The 12-year-old boy stepped out of bed and straight into knee-deep floodwaters from the nearby Guadalupe River. Before long, the water had already risen to his waist. In the darkness, he managed to feel for his tennis shoes floating nearby, put them on, and escape to the safety of the hillside. All 400 people at the all-boys camp survived, even as they watched one of their cabins float a

Inside the struggle to create a cozy Lord of the Rings game

When new employees start at Weta Workshop, they’re herded into a meeting room with a long, unassuming conference table. On the walls, behind panes of glass and in between statues, swords, and masks, are five Oscars. Four of them were awarded to the studio for its efforts on Peter Jackson’s The Lord of the Rings films. New hires are offered a chance to hold one of those Oscars, but there’s a catch: handling the golden statuette marks you with a curse, preventing you from ever winning one yourself

Tesla vet says that ‘reviewing real products’ — not mockups — is the key to staying innovative

GM’s EVs have been on a roll lately. After selling just the Chevy Bolt for years, a wave of new models — now up to 17 fully electrified vehicles — has pushed the automaker into second place in the U.S. behind Tesla. How did it get there? With a little help from a Tesla veteran. GM board member Jon McNeil was president of Tesla during the development and introduction of the Model 3, a crucial period of the company’s growth. One of the things he credits for Tesla’s success is how Elon Musk ran p

Samsung DeX is taking a step back with One UI 8, and I don’t like it (yet)

Zac Kew-Denniss / Android Authority Samsung DeX has been around for eight years, and for many, it’s become a core part of the Samsung experience. DeX gives us the ability to turn our Samsung phones and tablets into ultra-portable laptop replacements, provided all you need is Android apps and a browser. While DeX has gained plenty of features since its introduction, it’s still fundamentally the same as it was in 2017. That’s changing with One UI 8, though, as Samsung has rebuilt DeX upon Android

Open Sauce is a confoundingly brilliant Bay Area event

This is the second year I brought my Dad (a now-retired radio engineer and co-host of Geerling Engineering) to Open Sauce, a Bay Area maker faire-like event, dreamed up by William Osman and featuring hundreds of exhibits ranging from mad science, to vintage electronics, to games, to world-record-breaking Rubik's Cube solvers: Sprawling over the grounds of the San Mateo County Event Center, I met people of all ages who were building all sorts of zany contraptions.

Index Ventures’ Jahanvi Sardana shares the truth about TAM and what founders should focus on instead

Early-stage founders just can’t get away from TAM — the concept of having a total addressable market for their startup to disrupt and conquer. But Index Ventures partner Jahanvi Sardana has a reminder for all those founders worried about finding TAM for their product or service: Many startups have emerged from markets that, at the time, were essentially nonexistent. “What was the market for search before Google?” Sardana asked the audience at TechCrunch’s 2025 All Stage event in Boston, held ea

Intel drops 8% as chipmaker's foundry business axes projects, struggles to find customers

Intel 's stock dropped more than 8% after the chipmaker said it would slash foundry costs in its latest attempt to turn around its struggling business.

CNET Survey: 64% of People Still Don't Want a Foldable Smartphone

Samsung has its eye on Perplexity and OpenAI as it plans to expand beyond Gemini

Ryan Haines / Android Authority TL;DR Samsung is reportedly looking to expand its AI offerings. The company is said to be in talks with multiple vendors, including OpenAI and Perplexity. The aim is to give Galaxy S26 users more choice over what AI model they use. Samsung has long been partnering with Google to bring Gemini to its Galaxy phones. While this partnership has served Samsung well, a new report suggests the company doesn’t want to be tied to only one outside AI model. The firm is s
