U.S. Proposes Clearer Groundwater Protection Standards for In-Situ Uranium Recovery Sites

The U.S. Nuclear Regulatory Commission (NRC) on September 1 proposed a rule aimed at establishing clearer groundwater protection standards for communities surrounding in-situ uranium recovery sites, while streamlining the process for extending decommissioning deadlines for radioactive materials facilities and nuclear reactors, reducing redundant administrative steps without compromising safety. The rule addresses two aspects under NRC oversight. First, it proposes risk-informed regulatory standards for protecting drinking water near in-situ uranium recovery facilities, designed to guard against both radiological and non-radiological contamination. In-situ uranium recovery is a method of uranium extraction that involves injecting solution into uranium-bearing ore bodies to dissolve underground uranium resources and pump them to the surface for recovery. Second, it proposes to simplify the process for facility owners to apply for extensions of decommissioning deadlines. The NRC stated that current time requirements are relatively rigid and may lead to premature license termination; the proposed changes aim to reduce applicant costs, improve regulatory efficiency, and provide clearer expectations for communities and facility operators.

U.S. Heavy-Ion Collision Research Suggests Protons and Neutrons May Not Be Just "Three Quarks"

The STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy's Brookhaven National Laboratory recently proposed, based on heavy-ion collision data studies, that baryons such as protons and neutrons may not be simply composed of three valence quarks, and that their baryon number may be more closely related to "baryon junctions" in the gluon field. The findings were published in the journal *Science*. In the traditional valence quark model, each quark is assigned a baryon number of 1/3, so baryons such as protons and neutrons, composed of three quarks, carry a baryon number of +1. However, this model is not a fundamental requirement of quantum chromodynamics (QCD). As early as the 1970s, alternative explanations had been proposed in the theoretical community; in 1996, Dmitri Kharzeev proposed a model suggesting that the baryon number is not necessarily carried by the quarks themselves, but may instead be concentrated at the Y-shaped junction formed by the gluon field—the "baryon junction."

Portable X-ray Equipment in the U.S. Used for On-Site Assessment of American Football Injuries

As the 2026–2027 American football season approaches, team training camps, player evaluations, and medical support preparations are getting underway. Given the risk of acute sports injuries from the high-intensity physical contact in American football, portable X-ray equipment is being used to improve the efficiency of injury assessment on the sidelines and at training facilities. According to reports, American football players are prone to fractures, sprains, joint dislocations, and contusions. Relevant data indicates that the incidence of severe injuries such as fractures, dislocations, and contusions in this sport is higher than in other sports, with fractures accounting for approximately 10% of all football injuries. Such injuries typically require X-ray radiography to aid diagnosis, but traditional X-ray machines are bulky and fixed in place, usually requiring use in facilities with appropriate shielding. Injured players often need to be transported to the radiology department for examinations, which may delay diagnosis and treatment decisions.
