What will be the impact to the ocean if humans are to mine the deep sea? It’s a question that’s gaining urgency as interest in marine minerals has grown.
Physicists harness quantum “time reversal” to measure vibrating atoms（图）
量子 时间反转 振动原子 原子钟 量子传感器
2022/7/14
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
Water regulation in leaves is vital to a plant’s health, affecting its growth and yield, disease susceptibility and drought resistance.
Researchers to measure 'coronavirus slide' in kids' reading skills（图）
measure coronavirus slide kids reading skills
2020/5/7
Teachers have long been familiar with the "summer slide" -- the loss of reading skills among kindergarteners through second graders in the three months away from the classroom. Now researchers at Yale...
When a chemical spills, it's important to know how quickly the spill will spread. When irrigating a crop, a farmer needs to know how fast water moves through soil for absorption by roots. In both case...
