用干细胞制造出神经肌肉结点科学家首次使用干细胞在实验室中培育出了位于人体肌肉细胞和脊髓细胞之间的神经肌肉结点。这是利用不同浓度的细胞和不同的时间间隔以及其他参数制造出的二者结合的最合适环境,其为研制出“人体芯片”系统铺平了道路。未来可以借助“人体芯片”加快医学研究和药物测试的步伐,而不再需要使用传统方法耗费数年对药物进行动物和人体试验。首现宇宙大爆炸之后气体云天文学家们首次发现了宇宙大爆炸之后仅仅几分钟内形成的原始气体云,其中只发现了氢气及氢的重同位素——氘,氦元素虽无法确定,但碳、氧、硅等成分可确定并不存在。此气体成分结构符合先前理论预测,为现代宇宙论中关于宇宙元素起源的说法提供了直接证据。
Making Neuromuscular Nodes with Stem Cells Scientists used stem cells for the first time to create neuromuscular junctions between human muscle cells and spinal cord cells in the lab. This is the most suitable environment for the combination of different concentrations of cells and different time intervals, as well as other parameters, paving the way for the development of a “Human-Chip” system. In the future, we can speed up the pace of medical research and drug testing with the help of “human chips,” eliminating the need for years of traditional animal and human testing of drugs. After the first Big Bang, gas cloud astronomers first discovered the primitive gas cloud formed in just a few minutes after the Big Bang, in which only the heavy isotopes of hydrogen and hydrogen - deuterium were found - although the helium element was not known, carbon , Oxygen, silicon and other ingredients can be identified and does not exist. This gas composition is in line with previous theoretical predictions and provides direct evidence for the claim of modern cosmology about the origin of the universe.
