Single DNA molecule jamming and history-dependent dynamics during motor-driven viral packaging [0.03%]
单个DNA分子在电机驱动噬菌体包装过程中的堵塞及历史依赖性动力学行为

In many viruses molecular motors forcibly pack single DNA molecules to near-crystalline density into ~50-100 nm prohead shells1, 2. Unexpectedly, we found that packaging frequently stalls in conditions that induce net attractive DNA-DNA int...
The flagellar motor of Caulobacter crescentus generates more torque when a cell swims backward [0.03%]

Caulobacter crescentus, a monotrichous bacterium, swims by rotating a single right-handed helical filament. CW motor rotation thrusts the cell forward 1, a mode of motility known as the pusher mode; CCW motor rotation pulls the cell backwar...

A fundamental feature of multicellular organisms is their ability to self-repair wounds through the movement of epithelial cells into the damaged area. This collective cellular movement is commonly attributed to a combination of cell crawli...

The Carnot cycle imposes a fundamental upper limit to the efficiency of a macroscopic motor operating between two thermal baths1. However, this bound needs to be reinterpreted at microscopic scales, where molecular bio-motors2 and some arti...

The last 25 years have seen tremendous progress in thermometry in the moderate temperature range (1 K to 1235 K). Various primary thermometers - based on different physics -have uncovered errors in the International Temperature Scale of 199...
Hybridization-controlled charge transfer and induced magnetism at correlated oxide interfaces [0.03%]
强关联氧化物异界面处的杂化调控电荷转移及诱导磁性

At interfaces between conventional materials, band bending and alignment are classically controlled by differences in electrochemical potential. Applying this concept to oxides in which interfaces can be polar and cations may adopt a mixed ...
Quantum Coherence in Photosynthesis for Efficient Solar Energy Conversion [0.03%]
量子相干性在光合作用中的作用及高效太阳能转化
