The Hunt for a Fundamental Theory of Quantum Gravity

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally interwoven threads of space and time seem to stop short. These mysterious points are known as singularities. Singularities are predictions of Albert Einstein’s general theory of relativity. According to this theory, clumps of matter o

Max severity Cisco ISE bug allows pre-auth command execution, patch now

A critical vulnerability (CVE-2025-20337) in Cisco's Identity Services Engine (ISE) could be exploited to let an unauthenticated attacker store malicious files, execute arbitrary code, or gain root privileges on vulnerable devices. The security issue received the maximum severity rating, 10 out of 10, and is caused by insufficient user-supplied input validation checks. It was discovered by Kentaro Kawane, a researcher at the Japanese cybersecurity service GMO Cybersecurity by Ierae, and report

Transit software startup Via confidentially files for an IPO

Via, the transit software startup that garnered attention for its consumer-facing on-demand shuttle service, said it has filed confidentially for an initial public offering. Via has been batting around plans for an IPO for years. The company filed confidentially for an IPO in 2021, but never took the next official and regulatory steps to enter the public markets. Now, the company says it’s ready. Its status as a confidential filing, however, leaves lots of missing details, including the number

Voxtral – Frontier open source speech understanding models

Voice: the original UI. Voice was humanity’s first interface—long before writing or typing, it let us share ideas, coordinate work, and build relationships. As digital systems become more capable, voice is returning as our most natural form of human-computer interaction. Yet today’s systems remain limited—unreliable, proprietary, and too brittle for real-world use. Closing this gap demands tools with exceptional transcription, deep understanding, multilingual fluency, and open, flexible deploy

Uber and Baidu are teaming up to deploy thousands of autonomous vehicles globally

This will be happening in China and other "markets outside of the US." Uber and China-based Baidu are teaming up to deploy more autonomous vehicles throughout the world. The companies plan on bringing thousands of Baidu's Apollo Go vehicles to various regions that will be accessible via the Uber platform, including mainland China and other "global markets outside of the US." The first joint deployments are expected in Asia and the Middle East later this year. Once launched, Uber riders could b

Building community and clean air solutions

Darren Riley: Hi. Thanks for having me. Megan: Thank you ever so much for being with us. To get us started, let's just talk a bit about JustAir. How did the idea for the company come about, and what does your company do as well? Darren: Yeah, absolutely. The real thesis of JustAir, is really a combination of one, my personal experience but also my professional experience. On the professional side, background in software engineering, graduated from Carnegie Mellon University, but I was always f

Gigabyte motherboards vulnerable to UEFI malware bypassing Secure Boot

Dozens of Gigabyte motherboard models run on UEFI firmware vulnerable to security issues that allow planting bootkit malware that is invisible to the operating system and can survive reinstalls. The vulnerabilities could allow attackers with local or remote admin permissions to execute arbitrary code in System Management Mode (SMM), an environment isolated from the operating system (OS) and with more privileges on the machine. Mechanisms running code below the OS have low-level hardware access

NetBox Labs secures $35M as demand for network infrastructure management surges

The platform’s technical foundation centers on modeling infrastructure relationships in detail. The NetBox model encodes realistic relationships, such as an IP address’s provision on an interface, where the interface is on the switch, and where the switch sits in a rack. In addition, NetBox Labs has expanded the core platform with complementary products that address operational pain points while leveraging the central data repository. NetBox Discovery provides automated network device and serv

Cybersecurity’s global alarm system is breaking down

Cybersecurity practitioners have since flooded Discord channels and LinkedIn feeds with emergency posts and memes of “NVD” and “CVE” engraved on tombstones. Unpatched vulnerabilities are the second most common way cyberattackers break in, and they have led to fatal hospital outages and critical infrastructure failures. In a social media post, Jen Easterly, a US cybersecurity expert, said: “Losing [CVE] would be like tearing out the card catalog from every library at once—leaving defenders to sor

Measuring the impact of AI on experienced open-source developer productivity

We conduct a randomized controlled trial (RCT) to understand how early-2025 AI tools affect the productivity of experienced open-source developers working on their own repositories. Surprisingly, we find that when developers use AI tools, they take 19% longer than without—AI makes them slower. We view this result as a snapshot of early-2025 AI capabilities in one relevant setting; as these systems continue to rapidly evolve, we plan on continuing to use this methodology to help estimate AI accel

How passkeys work: Your passwordless journey begins here

CollinsChin/Getty Images Over the last few decades, compromised usernames and passwords have typically been at the root of some of the most sensational, damaging, and costly data breaches. An incessant drumbeat of advice about how to choose and use strong passwords and how not to fall prey to social engineering attacks has done little to keep threat actors at bay. Additional factors of authentication, such as the transmission of one-time passwords or passcodes (OTPs) over SMS or email, are wid

The Origin of the Research University

If you were alive in 1800 and someone asked you about the future of research, it wouldn’t occur to you to mention the university. Real scholarship happened in new, modern, enlightened institutions like the British Royal Society or the French Académie des sciences. Universities were a medieval relic. And nowhere was it more medieval, hidebound, and generally dysfunctional than in the German-speaking world. But something happened to German universities at the turn of the 19th century — they develo

‘Edge of Eternities’ Will Take ‘Magic: The Gathering’ to the Stars

A certain Star franchise may have boldly declared space the final frontier, but for Magic: The Gathering, it’s only the beginning. After the huge risk (and ultimate success) of its Final Fantasy set last month, the venerable card game is leaping into another big risk, although this time devoid of any flashy crossover: its next set, Edge of Eternities, will mark Magic‘s first proper foray into full-on science fiction. The series has flirted with sci-fi concepts across its fantastical settings fo

Stalking the Statistically Improbable Restaurant with Data

Last summer, I wrote about the statistically improbable restaurant, the restaurant you wouldn’t expect to find in a small American city: the excellent Nepali food in Erie, PA and Akron, OH; a gem of a Gambian restaurant in Springfield, IL. Statistically improbable restaurants often tell you something about the communities they are based in: Erie and Akron have large Lhotshampa refugee populations, Nepali-speaking people who lived in Bhutan for years before being expelled from their county; Sprin

Identities of More Than 80 Americans Stolen for North Korean IT Worker Scams

For years, the North Korean government has found a burgeoning source of sanctions-evading revenue by tasking its citizens with secretly applying for remote tech jobs in the West. A newly revealed takedown operation by American law enforcement makes clear just how much of the infrastructure used to pull off those schemes has been based in the United States—and just how many Americans' identities were stolen by the North Korean impersonators to carry them out. On Monday, the Department of Justice

Hundreds of Brother printer models have security flaw that can't be patched

This could allow bad actors to remotely access these devices. A security company has found eight security vulnerabilities that impact hundreds of Brother printer models. The company has released firmware updates to handle seven of these vulnerabilities, but one security flaw cannot be patched. Brother has indicated that it'll fix the remaining issue during the manufacturing process of future printers, which doesn't help current owners. The company recommends that users change the default main

US, French authorities confirm arrest of BreachForums hackers

U.S. and French authorities have confirmed the arrests of five hackers accused of being behind several major hacks and being part of a notorious cybercrime forum. On Thursday, the U.S. Department of Justice announced the indictment of British national Kai West, 25, accusing him of being “a serial hacker” known as IntelBroker. U.S. authorities allege West is behind “a years-long hacking scheme,” which caused more than $25 million in damages by targeting more than 40 victims, including a telecoms

AI Agents Are Getting Better at Writing Code—and Hacking It as Well

The latest artificial intelligence models are not only remarkably good at software engineering—new research shows they are getting ever-better at finding bugs in software, too. AI researchers at UC Berkeley tested how well the latest AI models and agents could find vulnerabilities in 188 large open source codebases. Using a new benchmark called CyberGym, the AI models identified 17 new bugs including 15 previously unknown, or “zero-day,” ones. “Many of these vulnerabilities are critical,” says

The All-In Podcast’s $1,200 tequila has already sold out

In Brief The VCs, pod bros, and self-proclaimed “besties” of the All-In Podcast launched their own tequila brand Saturday night and it promptly sold out, according to liquor ecommerce sites. Their version of the Mexican spirit cost a jaw-dropping $1,200 apiece but only 750 bottles were made. The stacked poker-chip container was inspired by the “besties” love of the card game. The All-In Podcast is one of the most popular shows by venture investors who have turned to politics. The besties cons

Early US Intel assessment suggests strikes on Iran did not destroy nuclear sites

CNN — The US military strikes on three of Iran’s nuclear facilities last weekend did not destroy the core components of the country’s nuclear program and likely only set it back by months, according to an early US intelligence assessment that was described by four people briefed on it. The assessment, which has not been previously reported, was produced by the Defense Intelligence Agency, the Pentagon’s intelligence arm. It is based on a battle damage assessment conducted by US Central Command

XBOW, an autonomous penetration tester, has reached the top spot on HackerOne

For the first time in bug bounty history, an autonomous penetration tester has reached the top spot on the US leaderboard. Our path to reaching the top ranks on HackerOne began with rigorous benchmarking. Since the early days of XBOW, we understood how crucial it was to measure our progress, and we did that in two stages: First we tested XBOW with existing CTF challenges (from well-known providers like PortSwigger and Pentesterlab), then quickly moved on and built our own unique benchmark that

Amazon says it's expanding same-day and next-day delivery to 4,000 more small cities and towns

Something to look forward to: Amazon managed to revolutionize e-commerce with fast and affordable shipping, but it isn't resting on its laurels. The Seattle-based online retailer recently announced plans to further expand the reach of its same-day and next-day delivery services to tens of millions of additional customers in the US by the end of the year.
