Defecation is commonly treated as a universal feature of animal life, a visible outcome of digestion and metabolic turnover.

They drew with crayons, possibly fed on maggots and maybe even kissed us: Forty millenniums later, our ancient human cousins ...

Animal stripes and spots might look decorative, but they’re the result of deeply complex biological processes that begin long ...

多类拓扑半金属在拓扑带交叉处具有相反手性的费米子。拓扑系统中的手性费米子输运通常依赖于强磁场或磁掺杂剂来抑制平凡输运，并造成相反陈数态占据数的不平衡。 研究组利用拓扑带的量子几何特性，通过手性将费米子滤入不同的陈数极化态。这实现了具有相反手性的费米子电流在实空间中分离，通过观察其在无外加磁场条件下的量子干涉，研究组证明了这一点。 由单晶PdGa制成的三臂构型器件表现出量子几何诱导的手性费米子异常速 ...
