Claude-powered AI coding agent deletes entire company database in 9 seconds — backups zapped, after Cursor tool powered by Anthropic’s Claude goes rogue

PocketOS founder blames ‘Cursor running Anthropic’s flagship Claude Opus 4.6’ plus Railway’s infrastructure for data disaster.

Medicine’s next leap: Delivering gene therapies exactly where they’re needed

A quiet revolution is underway in modern medicine: Drug development is aiming to move from managing disease to correcting it through RNA and gene-editing therapies. But delivering these treatments safely and precisely to the right cells remains a major hurdle—especially in hard-to-target organs like the brain and kidneys.

Now, researchers led by a University of Ottawa Faculty of Medicine team offer highly compelling evidence that an elegant, nature-inspired solution lies in ultra-tiny, bubble-like structures called small extracellular vesicles (sEVs). These metabolic messengers, refined over millions of years of evolution, carry RNA—a nucleic acid that is a chemical cousin of DNA—and other molecules between cells.

In a nutshell, the research team’s new findings show that not all sEVs are alike: their cell of origin determines where they travel, with certain vesicles naturally targeting specific tissues in the body.

Predictors of major adverse cardiac events, high radiation

Percutaneous coronary intervention (PCI) for calcified lesions poses risks of major adverse cardiac events (MACE), increased radiation exposure, and contrast use for patients.

Airborne desert dust may warm climate far more than expected, new analysis shows

Atmospheric dust plays a dual role in Earth’s climate: it reflects some sunlight back into space while also absorbing and retaining the planet’s heat like an insulating blanket. But while dust likely cools the planet overall, that’s not the whole story. New UCLA research shows that the heat-trapping effect of airborne desert dust in the atmosphere is about twice as big as previously believed.

Although researchers emphasized that current climate models are performing well, the new findings will further increase precision. Updating climate and weather models to account for the larger heat-trapping power of dust could improve both short-term weather forecasts and long-term climate projections, said lead researcher and UCLA atmospheric scientist Jasper Kok.

Using data from satellites, aircraft measurements and new climate simulations, combined with meteorological data related to temperature, UCLA-led researchers developed a global estimate, shared in a study published in Nature Communications.

Elicited Repetitive Daily Blindness Associated With Gain-of-Function SCN1A Variants and Responsiveness to Sodium Channel Blockers

Study demonstrates that elicited repetitive daily blindness is a clinical feature in patients with familial hemiplegic migraine 3 because of gain-of-function Nav1.1 variants. Patients in this report responded to sodium channel blocker medications.

Phage immunoprecipitation sequencing is a powerful technique that can quantify antibody binding to all known viruses, human proteome, bacterial toxins, and allergens

https://doi.org/10.1172/jci.insight.203645 Here, Aaron A.R. Tobian & team use this method to evaluate antibody repertoires in kidney donors with and without HIV, reporting that antibodies against adenovirus infection in kidney donors with HIV may be associated with allograft rejection.

Early fibrotic niches establish tumour-permissive microenvironments

Pathologic transformation in KrasG12D-mutant alveolar type II cells initiates a tumour-permissive niche by orchestrating epithelial, stromal and immune reprogramming through amphiregulin–EGFR signalling, creating a self-sustaining circuit critical for lung tumour initiation and progression.

Atomic Clocks: Exquisite Sensors for More Than Just Time

Atomic clocks use the quantum energy levels of atoms to tell time more accurately and precisely than any other kind of clock. (Learn more about how atomic clocks work.)

But atomic clocks can be used for more than timekeeping. They can serve as quantum sensors. Indeed, companies already use portable atomic clocks to detect oil deposits under the ocean. As these clocks become even more accurate and precise, their sensing capabilities become increasingly powerful.

To understand how atomic clocks work as sensors, we need to know a bit about Einstein’s theory of general relativity. Relativity tells us that time ticks more slowly in stronger gravity. Here on Earth, for example, a clock ticks slightly more slowly at sea level than it would on the top of a mountain, because gravity is stronger at sea level. For similar reasons, clocks in space speed up relative to those on Earth.
