Atomic-scale manufacturing now a reality  

Scientists have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. The vastly greener, faster, smaller technology enabled by this development greatly reduces impact on the climate while still satisfying the insatiable demands of the information age.

Chimpanzee calls differ according to context  

An important question in the evolution of language is what caused animal calls to diversify and to encode different information. A team of scientists has found that chimpanzees use the quiet 'hoo' call in three different behavioral contexts -- alert, travel and rest. The need to stay together in low visibility habitat may have facilitated the evolution of call subtypes.

Controlled nano-assembly  

DNA, the carrier of genetic information, has become established as a highly useful building material in nanotechnology. One requirement in many applications is the controlled, switchable assembly of nanostructures. Scientists have now introduced a new strategy for control through altering pH value. It is based on ethylenediamine, which only supports the assembly of DNA components in a neutral to acidic environment -- independent of the base sequences and without metal ions.
