Quantum physicists have developed an algorithm that uses a single qubit to solve a problem that had previously needed thousands of them.
A new material can withstand ‘billions’ of electrical cycles without wearing out — and scientists say it could transform electronics within 10 to 20 years.
A silent symphony is playing inside your brain right now as neurological pathways synchronize in an electromagnetic chorus that’s thought to give rise to consciousness.
Yet how various circuits throughout the brain align their firing is an enduring mystery, one some theorists suggest might have a solution that involves quantum entanglement.
The proposal is a bold one, not least because quantum effects tend to blur into irrelevance on scales larger than atoms and molecules. Several recent findings are forcing researchers to put their doubts on hold and reconsider whether quantum chemistry might be at work inside our minds after all.
A new publication has discovered ways to reduce the toxicity of graphene oxide (GO), an ultra-thin sheet of nanomaterial derived from graphite, laying the groundwork to use it as a drug delivery system.
Professor Khuloud Al-Jamal, who led the study, said: “Researchers have been incredibly excited in the potential medical applications of graphene since experiments into the nanomaterial were recognised with the Nobel Prize in Physics in 2010. However, concerns around toxicity have remained a consistent obstacle.”
Graphene oxide (GO) is an ultra-thin sheet derived from graphite. It is similar to pencil lead but includes attached oxygen atoms, making it compatible with water. Its unique physical and chemical properties mean it has a high capacity for carrying antibiotics and anticancer drugs, among others, as well as targeting specific cells, making it a potentially effective drug delivery system.
To understand where artificial intelligence might be heading, we must first understand what consciousness, the self and free will mean in ourselves.
Long before “ex Machina” trotted out the standard “creation kills creator” storyline, real science fiction authors explored the idea of human/machine relatio…
AI might be able to allow aliens to communicate in real-time with humans — or a language model representing us, at least.
Nearly invisible, seaweed-based electronic skin precisely monitors pulse pressure and temperature, rivaling medical equipment in accuracy with its innovative bioelectronic design.
Theories of computation and theories of the brain have close historical interrelations, the best-known examples being Turing’s introspective use of the brain’s operation as a model for his idealized computing machine (Turing 1936), McCulloch’s and Pitts’ use of ideal switching elements to model the brain (McCulloch and Pitts 1943), and von Neumann’s comparison of the logic and physics of both brains and computers (von Neumann 1958).
Electrically addressable VO2 elements show large resonance shifts during phaseions, producing a brilliant colour change at a modulation rate of 70 kHz.
