Schools in the States simply admit a lot more students than is usual in most other countries. Also, most young American university students have not traveled in other countries and are not very well-versed in international matters and do not know a lot about people from other countries. Foreig...
US chemist George Whitesides’ suggestion that chemistry should move ‘away from the molecule’ (in a paper provocatively titled ‘Is the focus on “molecules” obsolete?’)2raises the question of what, exactly, it is that the subject should...
In addition, nitration could be mediated by nitrogen dioxide (NO2̇), which is an important environmental toxin and a byproduct of the reaction of NO with O2. If solely dependent on NO2̇, this mechanism would require two molecules of the oxidant and is therefore less likely to occur ...
resemble miniaturized versions of beaded Chinese finger traps. Microtubules can grow 1,000 times as long as their widths. Fabricated by the assembly of dimers – a single molecule, or two identical molecules joined together of alpha and beta tubulin – microtubules exist in both plant and animal...
The mechanism of memory remains one of the great unsolved problems of biology. Grappling with the question more than a hundred years ago, the German zoologist Richard Semon formulated the concept of the engram, lasting connections in the brain that result from simultaneous “excitations”, whose pr...
Since the cancer stem cell concept has been widely accepted, several strategies have been proposed to attack cancer stem cells (CSC). Accordingly, stem cell markers are now preferred therapeutic targets. However, the problem of tumor specificity has not
Ultimately the gas consists of lots of molecules bouncing around in a complicated way that’s full of computational irreducibility. But it’s a central fact of statistical mechanics that if we look at the gas on a large scale, we can get a useful description of what it does jus...
However, the greater amount of work in this field, which is not aimed at acquiring signals but rather molecules and cells, requires larger reaction loads. For example, to construct reaction systems, small area chips are difficult for such work, and as a disposable consumable, the market space...
