Национальная академия наук Беларуси организует проведение XX Международной научной конференции молодых ученых «Молодежь в науке – 2023» (20–22 сентября 2023 г.). В ходе мероприятия планируется работа ряда секций для молодых ученых, аспирантов, магистрантов и студентов по аграрным, биологическим, гуманитарным, медицинским, физико-математическим, физико-техническим наукам, а также по химии и наукам о Земле. Организационный взнос для участия не предусмотрен. Прием заявок и тезисов докладов для участия до 1 июля 2023 г. Подробная информация размещена на сайте Конференции: https://sites.google.com/view/youthinscience/
People stuck sitting in tight airplane seats for an entire long-haul flight are at risk of dangerous blood clots. But somehow immobile, hibernating bears are not. Now scientists know why. Bears settled in for winterlong slumbers have low levels of a key protein that helps blood clots form, researchers report in the April 14 Science. Platelets lacking this protein don’t easily stick together, protecting the animals from developing potentially dangerous blood clots. And low levels of the protein are not just found bears, the team writes. Mice, pigs and humans with a largely sedentary lifestyle because of long-term mobility problems have the same protection.
An explosion at the Chernobyl Nuclear Power Plant in 1986 spread a radioactive cloud over large parts of the Soviet Union, now the territories of Belarus, Ukraine and the Russian Federation. Nearly 8.4 million people in the three countries were exposed to the radiation.
Prairie voles have long been heralded as models of monogamy. Now, a study suggests that the “love hormone” once thought essential for their bonding — oxytocin — might not be so necessary after all. Interest in the romantic lives of prairie voles (Microtus ochrogaster) was first sparked more than 40 years ago, says Devanand Manoli, a biologist at the University of California, San Francisco. Biologists trying to capture voles to study would frequently catch two at a time, because “what they were finding were these male-female pairs,” he says. Unlike many other rodents with their myriad partners, prairie voles, it turned out, mate for life. Pair-bonded prairie voles prefer each other’s company over a stranger’s and like to huddle together both in the wild and the lab. Because other vole species don’t have social behaviors as complex as prairie voles do, they have been a popular animal system for studying how social behavior evolves.
