Researchers at University of Tsukuba have developed an evaluation method for measuring and classifying trace element concentrations in the semen and blood serum of male patients with subfertility. This method demonstrated that the pregnancy rate was highest in the group with low phosphorus and arsenic concentrations and high concentrations of other trace elements. Thus, this method could be a novel approach for evaluating subfertility that does not rely solely on sperm concentration and motility.

Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. 

A new study from the University of Delaware demonstrates a way to diminish the impact that tires have on the environment when they can no longer be used on vehicles. The process upgrades 6PPD – a useful but environmentally harmful molecule that helps tires last longer – into safe chemicals.

Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure communication, advanced imaging, and precision optical tools. By carefully designing and positioning a quantum dot within a nanoantenna, they achieved high-quality light with over 93% polarization purity. This breakthrough helps improve the efficiency and practicality of devices that use structured light, paving the way for advancements in communication and optical technology.
