The time has come to create a new kind of computer, say researchers from John Hopkins University together with Dr. Brett Kagan, chief scientist at Cortical Labs in Melbourne, who recently led development of the DishBrain project, in which human cells in a petri dish learnt to play Pong.

In an article published today (March 1) in Frontiers in Science, the team outlines how biological computers could surpass today’s electronic computers for certain applications while using a small fraction of the electricity required by today’s computers and server farms.

They’re starting by making small clusters of 50,000 brain cells grown from stem c...

Astrophysicists discover the closest and oldest ultracool dwarf binary ever observed. Northwestern University and the University of California San Diego (UC San Diego) astrophysicists have discovered the tightest ultracool dwarf binary system ever observed.

The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star’s “year” lasts just 17 hours.

The newly discovered ...

A major new study in the journal Nature reveals a ‘traffic light’ mechanism controlling genetic activity within cells – a system which could potentially be targeted by cancer drugs already in development...

Physicists led by Roland Wester of the University of Innsbruck have now for the first time observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. With the study published in Nature, the scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.

Tunneling reactions in chemistry are very difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four particles it is almost impossible. Theorists simulate these reactions with classical physics and must neglect quantum effects...
