An advance toward ultra-portable electronic devices

Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a ...

Chemists slide a splitting catalyst over DNA for the first time

Chemists from Nijmegen, The Netherlands, have developed a catalyst that binds to DNA, slides over it and splits the molecule in particular places. The researchers were able to do this by synthetically modifying a natural ...

A new method for the formation of fluorinated molecular rings

Dyes, pharmaceuticals, and functional materials are generally based on innovative molecules made by chemists. For their production, several chemical reactions are available, but there are limitations. For example, fluorinated ...

Chromosome motor discovery supports DNA loop extrusion

It is one of the great mysteries in biology: How does a cell neatly distribute its replicated DNA between two daughter cells? For more than a century, we have known that DNA in the cell is comparable to a plate of spaghetti—a ...

Creating life-saving drugs from deadly venom

When faced with a scorpion, poisonous snake, jellyfish or tarantula, most people would beat a hasty retreat. For a team of scientists investigating the therapeutic potential of their venom, these are however very treasured ...

Why 'soot' could be the key to delivering drugs to cancer cells

Nano-scale tubes made of carbon could be used to safely penetrate human cells and deliver anti-cancer medicines or modified DNA molecules for gene therapy. Although there is a long way to go before the concept can undergo ...
