Around 1000 markings on a slab of rock that was once a seafloor during the Cretaceous period may have been made by sea turtle flippers and swiftly buried by an earthquake

Vertebral artery dissection may present as an isolated cervical radiculopathy sparing the central nervous system—an unusual presentation requiring differentiation from Parsonage-Turner syndrome, thoracic outlet syndrome, and other etiologies of cervical radiculopathy.

A joint research team has made important progress in the field of photoneutron cross section measurement. The team proposed a substitution measurement method that avoids the use of expensive and hard-to-prepare high-purity isotope targets, successfully measuring the ⁶⁵ Cu(γ, n)⁶⁴ Cu reaction cross section with high precision. This method only relies on natural copper (natCu) and previously measured copper-63 (⁶³ Cu) data, without modifying experimental facility parameters, making it simple, efficient, and low-cost.

The related research results have been published in the journal Nuclear Science and Techniques. The team includes researchers from Henan Normal University, Shanghai Advanced Research Institute of the Chinese Academy of Sciences, Shanghai Institute of Applied Physics of the Chinese Academy of Sciences, and other institutions.

A Rutgers researcher and collaborators have linked unusual geological anomalies to Earth’s molten origins and its unique habitability. For many years, researchers have struggled to understand two enormous and puzzling formations hidden deep within Earth. Their immense size and unusual traits make

Fluent Bit, deployed in billions of containers, has five new flaws enabling log tampering, remote code execution, and cloud takeover paths.

There are quite a few copies of this Feynman lecture floating around out there, but most end prior to the question from the audience.

After the lecture, a guy in the audience asks Feynman about his safe-cracking stories and Feynman goes on for about another ten minutes relating three different stories on his safe-cracking while at Los Alamos National Laboratories. Enjoy!
