The September 2021 issue of Toxicological Sciences contains leading toxicological research, exploring nanotoxicology, neurotoxicology, immunotoxicology, and more.
Infertility is estimated to affect 9% of reproductive-aged couples globally, and many couples turn to assisted reproductive technology. Selecting embryos with maximum development potential plays a pivotal role in obtaining the highest rate of success in ART treatment.
Researchers can evaluate the quality of an embryo by detecting the content of proteins secreted. In Biomicrofluidics, a method to detect trace proteins secreted by embryos using microfluidic droplets and multicolor fluorescence holds promise to select embryos for ART.
Scientists repurposed living frog cells—and assembled them into entirely new life-forms. These tiny “xenobots” can move toward a target and heal themselves after being cut. These novel living machines are neither a traditional robot nor a known species of animal. They’re a new class of artifact: a living, programmable organism.
