Intel’s goal is to build chips that work more like the human brain. Now its engineers think they know how
A new class of imaging device with no lens and just a single light sensitive sensor could revolutionise optical, infrared and millimetre wave imaging
Last week, Paul Allen and a colleague challenged the prediction that computers will soon exceed human intelligence. Now Ray Kurzweil, the leading proponent of the “Singularity,” offers a rebuttal.
Physicists have built a graphene battery that harvests energy from the thermal movement of ions in solution
Graphite and diamond have similar free energies but converting one into the other is famously hard. Now materials scientists think they know why
A growing body of evidence suggests that the molecular machinery of life emits and absorb photons. Now one biologist has evidence that this light is a new form of cellular communication.
A new way to analyze human reaction times shows that the brain processes data no faster than 60 bits per second.
Sudoku fanatics have long claimed that the smallest number of starting clues a puzzle can contain is 17. Now a year-long calculation proves there are no 16-clue puzzles.
