那么,为何会出现“腊梅”一词?“腊梅”的说法,宋代以后就有了。专家推测,大概率是因为蜡梅在寒冬腊月盛开,就有人写作了“腊梅”。腊月开花的既有蜡梅,也有梅花。因此“腊梅”一词不仅可以用来指代蜡梅,也可以用来指代在腊月开放的梅花。

Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.

And as for their noise-cancelling features, Mangino says "The ANC on this pair of headphones is just right, too. It isn't the best I've ever experienced, which isn't entirely surprising since the ear cups aren't particularly snug; that's great for comfort, but less effective for passive noise cancellation. But I find that its ANC easily blocks out the noise of busy city streets and the clink and clatter of my local coffee shop."
