Guatemala has opted out of renewing a lease agreement
on a 7,000-acre oil field in order to use the land for better protection of the surrounding Laguna del Tigre Biosphere Reserve.
An 830,000-acre component of the greater Mayan Biosphere Reserve
which allows Mesoamerican wildlife to roam freely between the country and neighboring Belize and Mexico,
it’s one of the world’s most important protected areas.
As such, the presence of an oil field inside its borders wa…

Can two Amazons survive? Invisible e-waste is poisoning the world
“I live in Accra, Ghana,” says Isaac Dinwe, who works for Closing the Loop, a Dutch company that works with the electronics industry to increase global recycling. “The e-waste problem in my country is so huge we are unable to manage it. Most of our e-waste ends up in city centres. Informal workers extract what […]

Abstract: The n2EDM experiment at the Paul Scherrer Institute aims to conduct a high-sensitivity search for the electric dipole moment of the neutron. Magnetic stability and control are achieved through a combination of passive shielding, provided by a magnetically shielded room (MSR), and a surrounding active field compensation system by an Active Magnetic Shield (AMS). The AMS is a feedback-controlled system of eight coils spanned on an irregular grid, designed to provide magnetic stability to the enclosed volume by actively suppressing external magnetic disturbances. It can compensate static and variable magnetic fields up to $\pm 50$ $\mu$T (homogeneous components) and $\pm 5$ $\mu$T/m (first-order gradients), suppressing them to a few $\mu$T in the sub-Hertz frequency range. We present a full finite element simulation of magnetic fields generated by the AMS in the presence of the MSR. This simulation is of sufficient accuracy to approach our measurements. We demonstrate how the simulation can be used with an example, obtaining an optimal number and placement of feedback sensors using genetic algorithms.

Extended Validation not so... extended? How I revoked $1,000,000 worth of EV certificates!
Personal like or dislike of EV aside for a moment, we can all agree on what the name of EV certs implies. Organisations get their company details in the certificate and CAs have to do some extended validation of that data compared to a normal certificate. Turns out, that doesn't

Netflix said on Thursday that it had backed away from its deal to acquire Warner Bros. Discovery,
-- a stunning development that paves the way for the storied Hollywood media giant to end up under the control of rival bidder, the MAGA friendly technology heir David Ellison.
Netflix said that it would not raise its offer to counter a higher bid made earlier this week by Mr. Ellison’s company, Paramount Skydance,
adding in a statement that “the deal is no longer financially a…

Diversifying lithium-rich mineral sources with petalite
Demand for lithium is surging, as the world transitions to renewable energy and adopts new technologies. Lithium-ion batteries play a central role in this shift, powering everything from cars to portable electronics. To meet the increasing demand, companies are recycling lithium from old batteries and also looking for new sources and better ways to extract it. While recycling supports a circular economy, experts agree that recycled lithium alone will not meet projected future needs.
