Wiz’s CTO on PHP2Shell and the coming ‘vulnpocalypse’

Two critical bugs in PHP, the open source language used by roughly 70% of websites, forced organizations to patch urgently, with some taking sites offline. Wiz's Tomer Schwartz discusses the fix effort alongside OpenAI, Calif and the PHP team, and warns that AI is speeding up discovery and exploitation of vulnerabilities.

Eaton Fire may have exposed nearly 7 million people to elevated lead levels

Caltech researchers analyzed smoke from the January 2025 Eaton Fire and found the urban plume far richer in toxic metals than wildfire smoke, including more than 50-fold more lead. They estimate nearly 7 million people in the Los Angeles area faced lead levels about 80 times typical values at the peak.

On the Ethics of Making People Feel Uncomfortable

Using David Foster Wallace's essay on boiling lobsters alive, Marianne Janack asks whether it is wrong to make people confront ethical questions they cannot immediately change. She draws on Descartes, Malebranche, and Beauvoir and Sartre's idea of facticity to argue that comfortable ignorance is easier but not better.

The Next Congress Needs to Reclaim Its Oversight of the Department of Defense

The article argues that the Trump administration has expanded executive power over the Department of Defense while Congress has largely deferred. It says the FY26 and FY27 defense authorization bills quietly give Congress tools to reassert oversight, and that a future Congress should use them.

Attempting to clean up the feature activation syntax?

A Cargo maintainer examines the confusing overlap of feature activation forms like foo/bar, dep:foo and foo?/bar, and proposes a phased cleanup: deprecate foo/bar in manifests, change CLI semantics under a new resolver, and possibly reintroduce foo/bar later. Downsides noted include Cargo.lock bloat and index syntax concerns.

U.S. moves to weaken methane limits on oil and gas producers

President Trump announced a major rollback of Biden-era methane rules for oil and gas producers, with the EPA claiming $45 billion in savings. Proposed changes would end the Super Emitter Program and loosen rules on marginal wells and routine flaring of associated gas, while critics call the standard toothless.

Macromolecular crowding could help build artificial cell systems

A Science Tokyo study found that macromolecular crowding agents such as PEG, dextran and Ficoll raise the temperature at which synthetic DNA nanostar droplets form. Adjusting PEG, nanostar ratios and salt levels also let researchers organize distinct droplets into patterns without fusion, supporting programmable artificial cell design.

Brazil's Flávio Bolsonaro flees to U.S. after election loss

Three days after Brazil's presidential election, Flávio Bolsonaro, who faces criminal investigations, defied a court order and left for the U.S. via Argentina and Ecuador. Analyst Brian Winter doubts a government-in-exile strategy will work, and notes President Trump voiced approval of his arrival while keeping some distance.

Atomic magnetism reveals why iron, but not chromium, can produce ammonia using sunlight

Researchers at the University of Vienna and TU Wien explain why an iron-based metal-organic framework photocatalyzes ammonia formation from nitrogen under light while its chromium analogue does not. Differences in magnetic coupling within the metal triangles set how strongly nitrogen binds, which determines catalytic success.

Ultrathin metal layer boosts spin-related signals, opening a door to ultralow-power electronics

Kyushu University researchers found that inserting an ultrathin iridium manganese layer between a YIG magnetic insulator and platinum boosts both the spin Seebeck effect and spin Hall magnetoresistance. A 0.3 nm layer gave the strongest responses, which could inform ultralow-power, battery-free devices.
