Just as a medication bottle might be opened and the tamper seals carefully reattached by a bad guy, the International Atomic Energy Agency is concerned its devices could be bypassed and repaired or counterfeited. A possible solution? Engineers at Sandia National Laboratories have developed a groundbreaking prototype using “bruising” materials. Their innovation doesn’t just detect tampering; the new device boldly displays the evidence, like battle scars.

Neutrons, known for their ability to penetrate materials deeply, are key in nondestructive material analysis. Techniques like Neutron Resonance Analysis (NRA) and its variant, Neutron Resonance Transmission Analysis (NRTA), use these properties to identify elements and isotopes inside materials without damaging them.

Colliding two heavy nuclei produces quark-gluon fireballs from which subatomic particles emerge. Fluctuations in the number of these particles from collision to collision carry important information about the QGP. Researchers used an approach called the maximum entropy principle to provide a crucial connection between experimental observations and the hydrodynamics of the QGP fireball.
