The Russia-Ukraine conflict that broke out in 2022 will have a major impact on the world's economy from the financial market, energy market, and agricultural product market. Ukraine has fertile black land in Eastern Europe. It is an important exporter of agricultural products in the world and an important way point for Russia to export energy. Russia is also one of the most important exporters of energy and agricultural products in the world. This article analyzes the reasons for the conflict between Russia and Ukraine from the perspective of geopolitics, and further combines data and charts to analyze the impact of the event on the world economy. This article can make the government aware of the dangers of war to human society and that only peaceful coexistence between countries can make mankind better. With rapid development, investors should reduce their investment during the war, so as not to lose their property.

Synaptic configurations in precisely wired circuits underpin how sensory information is processed by the nervous system, and the emerging animal behavior. This is best understood for chemical synapses, but far less is known about how electrical synaptic configurations modulate, in vivo and in specific neurons, sensory information processing and context-specific behaviors. We discovered that INX-1, a gap junction protein that forms electrical synapses, is required to deploy context-specific behavioral strategies during C. elegans thermotaxis behavior. INX-1 couples two bilaterally symmetric interneurons, and this configuration is required for the integration of sensory information during migration of animals across temperature gradients. In inx-1 mutants, uncoupled interneurons display increased excitability and responses to subthreshold temperature stimuli, resulting in abnormally longer run durations and context-irrelevant tracking of isotherms. Our study uncovers a conserved configuration of electrical synapses that, by increasing neuronal capacitance, enables differential processing of sensory information and the deployment of context-specific behavioral strategies.

(Abstracted from Obstet Gynecol 2022;140:305–310) Women of childbearing age are disproportionately affected by sexually transmitted infections (STIs), which lead to pelvic inflammatory disease and infertility, and have other serious implications. Sexual partners of patients diagnosed with gonorrheal or chlamydial infections are at high risk of STIs.

In this essay, Mingda Sun, a high school student from Connecticut, recounts her summer research internship opportunity at the Center for Quantitative Medicine of UConn Health. She discusses her learning experiences, the challenges she faced, and the encouragement she received from her mentors and peers and explains how this month-long internship helped her overcome her fears of the unknown, as the project was related to concepts that were new to her, like mathematical biology and computer science. Being part of a research team and committing herself to exploring new opportunities reaffirmed Sun’s career aspirations in science research in a STEM field. Her reflection offers helpful insights for students, educators, and researchers who are realizing the benefits that lab-based internship opportunities offer to both high school students and their instructors.
