Unzip, turn around, rezip

Tue, 10/09/2018 - 16:03
Scientists have long known that double-stranded DNA can be unwound into single-stranded DNA by molecular motor proteins called helicases, just like pulling a zipper. But researchers have discovered that the same machinery, after changing its shape, can also put the unwound DNA back together into double-stranded DNA.

Beware the fake graphene

Tue, 10/09/2018 - 11:39
A new study on worldwide graphene production shows unequivocally that the quality of the graphene produced in the world today is rather poor, not optimal for most applications, and most companies are producing graphite microplatelets. This is possibly the main reason for the slow development of graphene applications, which usually require a customized solution in terms of graphene properties. A conclusion that sounds even more damming is that this extensive study of graphene production worldwide indicates that there is almost no high quality graphene, as defined by ISO, in the market yet.
