New biochar strategy tackles toxic cadmium in rice paddies while locking away carbon

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

Rice paddies feed billions of people worldwide but face two major challenges: heavy metal contamination and greenhouse gas emissions. Now, researchers have developed a new type of biochar that can address both problems at once—immobilizing toxic cadmium in soil while helping trap carbon, a critical step in slowing climate change.

University of Phoenix publishes new white paper on microservice using achieved skills to build confidence between students and employers

University of Phoenix
Reports and Proceedings

University of Phoenix today announced the publication of a new white paper, “Leveraging Achieved Skills to Improve Confidence Between Students and Employers,” authored by Francisco Contreras and Brandon Edwards of the University’s careers product team. The paper outlines how a record of a learners’ achievements and attested skills can help students and employers speak a common language of skills, and help working adult learners see where they may qualify—and where they are close—before they apply.

Sustainable generative AI: UCLA develops novel light-based system

California NanoSystems Institute
Peer-Reviewed Publication

Researchers at the UCLA Samueli School of Engineering have created a technology capable of producing novel images using photonics — employing only a fraction of the energy and computational steps per image compared with an array of current generative AI programs.

This process requires only the initial digital encoding and successive optical decoding step; many current generative AI models typically require hundreds to thousands of iterative steps.

The optical generative models use a physical “key-lock” mechanism, preventing unauthorized reconstruction of generated images and offering security measures for communication, content delivery and foiling counterfeits.

New adaptive optics to support gravitational-wave discoveries

University of California - Riverside
Peer-Reviewed Publication

Gravitational-wave detection technology is poised to make a big leap forward thanks to an instrumentation advance led by physicist Jonathan Richardson of the University of California, Riverside. A paper detailing the invention, published in the journal Optica, reports the successful development and testing of FROSTI, a full-scale prototype for controlling laser wavefronts at extreme power levels inside the Laser Interferometer Gravitational-Wave Observatory.

Building trust in soil carbon as a climate solution requires stronger evidence

Yale University
Reports and Proceedings

As policymakers, markets, and the public look to soil carbon sequestration as a key climate solution, new research led by Yale School of the Environment scientists warns that current methods for measuring success may not be up to the task.
