16-Sep-2025 Mitochondria replenishment enhances senescent periodontal ligament stem cell osteogenesis and facilitates bone repair Tsinghua University Press Aging leads to mitochondrial dysfunction in periodontal ligament stem cells (PDLSCs), significantly impairing their osteogenic capacity—a critical barrier to bone regeneration in elderly populations. Researchers from Huazhong University of Science and Technology and Peking University demonstrated that replenishing aged PDLSCs with functional mitochondria from young counterparts restores mitochondrial integrity, reduces oxidative stress, and reactivates osteogenic capacity. This breakthrough, mediated by the AKAP1/cAMP/PKA signaling pathway, highlights mitochondrial replenishment as a promising therapeutic strategy for age-related bone defects and broader regenerative medicine applications.

16-Sep-2025 Taming AI with morals? Skeptical notes from a sociologist KeAi Communications Co., Ltd. If AI’s intrinsic risks are real, governmental regulation and ethical frameworks are unlikely to contain them. Drawing on social theory, it highlights myths about the state’s capacity, global enforcement challenges, rapid technological decentralization, and the ambiguity of moral norms. The author presents a skeptical view that “meaning well” does not ensure effective outcomes, cautioning against overreliance on governments and ethics to mitigate advanced AI risks.

15-Sep-2025 Arkansas Center for Food Safety fills gaps in research on hand sanitizers University of Arkansas System Division of Agriculture Researchers at the Arkansas Center for Food Safety examined the efficacy of five commercially available hand sanitizers with different active ingredients to fill gaps in understanding of their efficacy. The evaluation of hand sanitizers with 30 volunteers revealed that those who rubbed their hands with sanitizer until it was dry saw a greater reduction of viruses than those who rubbed their hands the typical 10 seconds. Also, the study supported other research that found product formulation, rather than just active ingredient concentration, impacted product efficacy.

15-Sep-2025 IEEE study demonstrate broadband optical signal filtering with chirped and tilted fiber Bragg grating Institute of Electrical and Electronics Engineers While fiber Bragg grating is widely used for selectively filtering wavelengths during optical transmission, existing techniques are unsuitable for bandwidth filtering of broadband optical signals. Researchers have now demonstrated that chirped and tilted fiber Bragg grating (CTFBG) using femtosecond laser line-by-line technology can facilitate highly specific and versatile bandwidth filtering in broadband signals. The technique may offer several added advantages in optical signal filtering beyond flexibility and customizability. Journal Journal of Lightwave Technology
