Physicists have reportedly shown all the necessary ingredients to create a nuclear clock, demonstrating impressive results with a laser device called a frequency comb. Marianna Safronova notes that this breakthrough indicates that the development of a nuclear clock is possible, emphasizing that the paper is among the most exciting in recent times. Although not yet a functioning clock, the promise it suggests for precise timekeeping is remarkable.
In a noteworthy study of trans men undergoing testosterone therapy, researchers found that their immune systems progressively resembled those of cis men. Blood samples taken at various stages of treatment revealed that as testosterone increased, the immune response shifted from virus-fighting proteins to those associated with muscle growth, signifying the influence of sex hormones on immune pathways and reflecting observed trends in disease susceptibility across genders.
