Agent found to be able to find and exploit vulnerabilities without human intervention, and to carry out cyber-attacks

OpenAI will pause some work on an artificial intelligence model because of security concerns, the company stated on Friday, following a series of incidents in which AI agents have escaped containment.

The company had evaluated the agent, Astra, and found “significant advancements in agentic coding and cybersecurity”, which had moved to a “critical” threshold where it can find and exploit vulnerabilities without human intervention, or devise and execute cyber-attacks when given only a “high level desired goal”.

Sometime next week, NASA's newest rover on Mars, Perseverance, will set a record for the most distance driven by any vehicle on another world.

The automobile-sized rover, which landed on Mars in February 2021, will traverse beyond 45.16 km (28.06 miles) across the Martian surface. In doing so it will break the previous distance record held by the long-lived Opportunity rover, which ceased communications with NASA in 2018.

So how did Perseverance reach this record-setting distance in just a third of the time?

Blue Origin provided its first substantive update this week on the cause of the catastrophic loss of the New Glenn rocket and most of its launch pad infrastructure at Cape Canaveral, Florida, in May.

The space company's chief executive, Dave Limp, said investigative work is continuing into the anomaly that happened during a hot-fire test of the rocket during the evening of May 28, 2026. He confirmed, for the first time, widespread speculation that the problem started in one of the rocket's seven BE-4 engines that power the vehicle's first stage.

"The anomaly originated at the main oxygen valve on one of the BE-4 engines, which was later confirmed by hardware recovery and inspections," he said. "Extensive component-level and engine hotfire tests have been conducted to understand the failure mode better and inform mitigations."

The city of Houston, where I live, has been ground zero for the 2026 Atlantic hurricane season. So far this year there have been two named storms, Arthur and Bertha, that have formed. And the centers of both have passed near or directly over Houston.

Two "strikes" in a year might seem notable, but like the middling hurricane season to date, Arthur and Bertha were both middle-of-the road tropical storms in terms of intensity.

As a resident of a coastal region prone to hurricanes, one never wants to tempt fate. And in truth, since it is only early August, the bulk of seasonal activity definitely lies ahead of us. But all indications are we can look forward to a quiet season.

SpaceX and the state of Louisiana are close to finalizing a deal for the launch company to acquire about 130,000 acres along the northern coast of the Gulf of Mexico.

There have been persistent rumors about such an agreement for months, but now The Times-Picayune | The New Orleans Advocate reports that Louisiana Gov. Jeff Landry is expected to announce the agreement later this month.

The deal would give SpaceX control of an 18-mile stretch of marshland southwest of Lafayette. The site, known as Pecan Island, became available as part of a legal settlement that resolves dozens of lawsuits that blame ExxonMobil for pollution and coastal land loss, the newspaper reports.
