Anthropic's Claude helps crack an 87-year-old math problem
Working with an Anthropic mathematician, the company's Claude model disproved the Jacobian conjecture, an algebraic-geometry problem open since 1939, by constructing a counterexample that another researcher then verified in the Lean proof checker. It follows recent AI wins on the International Math Olympiad and an 80-year-old Erdos conjecture.
Why it matters: AI is now resolving century-old research-level conjectures, not just contest problems, a shift mathematicians call rapid and unsettling for the field.

Trump's AI standards chief resigns after three months
Chris Fall stepped down as director of the Center for AI Standards and Innovation, the Commerce Department body that develops AI testing methods, after just three months on the job. NIST director Arvind Raman will serve as acting director while a permanent replacement is named.
Why it matters: Rapid turnover at the government's main AI-testing office undercuts US efforts to set credible safety and evaluation standards for frontier models.

Tech
Northrop Grumman launches a robotic mechanic for satellites in orbit
A SpaceX Falcon 9 lifted off from Cape Canaveral on July 21 carrying Northrop Grumman's Mission Robotic Vehicle, which uses a pair of robotic arms and a DARPA-funded Naval Research Laboratory payload to inspect, relocate, and repair aging satellites in geosynchronous orbit. After about a year in transit it will attach Mission Extension Pods to Optus and SES satellites to extend their lives.
Why it matters: It is the first operational US robotic satellite-servicing platform, pointing toward a future where costly spacecraft get repaired and refueled instead of abandoned as space junk.

A SharePoint zero-day is under attack as hackers steal server keys
Attackers are actively exploiting CVE-2026-50522, a critical (CVSS 9.8) remote code execution flaw in on-premises Microsoft SharePoint Server, after a public proof-of-concept appeared on July 20. Compromises let intruders steal server machine keys for lasting access, and CISA added the bug to its Known Exploited Vulnerabilities catalog on July 22.
Why it matters: Patching alone will not evict attackers who already grabbed machine keys, so organizations running on-prem SharePoint must also rotate credentials to be safe.

Business
Tesla posts record revenue but profit craters as EV credits vanish
Tesla reported record Q2 revenue of $28.24 billion, up 26%, on its best-ever quarter of 480,126 deliveries, but adjusted earnings of $0.33 a share badly missed the roughly $0.53 Wall Street expected. Operating income fell 57% to $398 million as regulatory-credit revenue collapsed 67% to $146 million after the federal EV tax credit expired.
Why it matters: The record volumes show demand is intact, but the vanished credit windfall exposes how much of Tesla's past profitability leaned on subsidies rather than car sales.

Google Cloud revenue rockets 82% on AI demand
Alphabet reported Q2 revenue of $119.8 billion, up 24% year over year, powered by Google Cloud revenue surging 82% to $24.8 billion, up from $13.6 billion a year earlier, on AI infrastructure demand.
Why it matters: Cloud's acceleration is the clearest sign yet that enterprise AI spending is translating into real, fast-growing revenue for the hyperscalers.

Science
The Milky Way flipped on its side after an ancient galactic smashup
Durham University astronomers running the Auriga simulations found our galaxy's disk likely tipped more than 90 degrees after a head-on collision with the Gaia-Sausage-Enceladus galaxy billions of years ago. Presented at the Royal Astronomical Society's National Astronomy Meeting, the work helps explain why the Milky Way's stellar halo rotates so slowly.
Why it matters: It suggests most of the galaxy's stars, possibly including our own Sun, once traveled on very different paths than they do today.

Scientists revive an antibiotic that superbugs had defeated
Researchers at Cold Spring Harbor Laboratory and Scripps Research used a small molecule to disable a bacterial enzyme, secreted antigen A, restoring the drug vancomycin's ability to kill drug-resistant E. faecium. The enzyme is common across resistant strains, making it a broad therapeutic target.
Why it matters: Reviving an existing drug rather than inventing a new one offers a faster path against hospital superbugs that current antibiotics can no longer touch.

Spain beats Argentina 1-0 to win the 2026 World Cup
Ferran Torres scored in extra time at MetLife Stadium in New Jersey on July 19 to give Spain a 1-0 win over Argentina and its second World Cup title, its first since 2010. The final was scoreless through regulation in what was likely Lionel Messi's last World Cup match.
Why it matters: It caps the first 48-team World Cup and closes the book on the Messi era at soccer's biggest tournament.

France becomes the first EU country to ban social media for under-15s
France's parliament passed a law barring children under 15 from platforms like TikTok and Snapchat, with age-verification checks on new accounts from September 2026 and existing accounts suspended from January 2027. It is a flagship initiative of President Macron's second term.
Why it matters: It sets a legal template that other European governments are now poised to copy, pushing the continent toward age floors for social media.

Future lands his 12th No. 1 album, passing Eminem among rappers
Future's new album 'The Real Me' debuts atop the Billboard 200 dated July 25 with 131,000 equivalent album units, his 12th career chart-topper. The total moves him past Eminem for the third-most No. 1 albums among rap acts.
Why it matters: It cements Future among the most commercially dominant rappers ever, trailing only Drake and Jay-Z on the all-time hip-hop leaderboard.

Apple TV+ takes over Comic-Con's Hall H for the first time
As San Diego Comic-Con opens, Apple TV+ will command Hall H for the first time on Saturday, July 25, with a two-hour showcase for 'Silo,' 'Matchbox,' 'Mayday,' 'Widow's Bay' and 'Dark Matter,' in the slot right before Marvel's return.
Why it matters: It signals streamers are now willing to fight for Comic-Con's biggest stage, a spotlight long dominated by legacy studios.
