- **B) called**:过去分词表被动,“被称作”,正确表达“particles被命名为molecules”的事实,符合被动语义。- **C) being called**:现在分词被动进行态,强调动作正在进行,但此处为普遍科学事实,无需进行时态,语法冗余。- **D) have called**:完成时主动态,无法作定语且主语需为主动执行者,与“particles”...

To find new drugs, scientists screen molecules to predict how effective they might be. Typically, such screening is done by humans in the lab, which is both costly and slow. Artificial intelligence is different. It's fast, and it can process a high volume. It can screen hundreds of millio...
"Sodium tetraborate (borax) is perfectly safe when used as directed, and it's one of the only chemicals known to link together long chains of glue molecules to make the traditional glue-based slime. "After unverified news articles were released in 2017 vilifying borax, leading glue ...
But test tubes are not bodies. Many drug molecules that appear to do their job in the lab end up failing when they are eventually tested in people. “The whole process of drug discovery is about failure,” says biologist Richard Law, chief business officer at Exscientia. “The reason that...

the biophysical nature of how multiple RPA molecules bind to long ssDNA has not been carefully explored. This is mainly due to the lack of a system that can quantitatively measure how multiple RPA molecules can change their binding modes during dynamic binding to long ssDNA. In this study, we...
Benefiting from the true nanoscale diameter which can facilitate the “slip effect” of air molecules, and the small pore size which can completely sieve ultrafine particles, the resultant 2D nanonets stand out as a promising material for promotion of air filtration applications21,31. Previously, ...
