om at quantum mechanics kan simulere komplekse systemer såsom transportsystem, børsen, vejret

Quantum RAM: Modelling the big questions with the very small
When it comes to studying transportation systems, stock markets and the weather, quantum mechanics is probably the last thing to come to mind. However, scientists have just performed a 'proof of principle' experiment showing that when it comes to simulating such complex processes in the macroscopic world quantum mechanics can provide an unexpected advantage


om evolution – og fænotypisk variation og co-evolution mellem arter med samme træk rettet mod fx samme prædator og co-evolution der forhindrer sammenbrud af et opstået samarbejde mellem arter

Studyfinds mutual reinforcement of phenotypic diversity and cooperation
A new model exploring how evolutionary dynamics work in natural selection has found that phenotypic diversity, or an organism's observable traits, co-evolves with contingent cooperation when organisms with like traits work together to protect themselves from outsiders, according to a study. The study also finds that diversity helps prevent the collapse of cooperation… "

om RSV en lungevirus uden vaccine eller behandling

Missing link for fighting viral pneumonia identified
According to the Centers for Disease Control, respiratory syncytial virus (RSV) causes about 60,000 hospitalizations of children aged 0 to four, and nearly 200,000 hospitalizations and 14,000 deaths among adults 65 and older. However, there are virtually no vaccines or treatments for these infections. In a new study, researchers found evidence that the cytokine, Interleukin 27 (IL-27), may be the..

Protecting quantum computing networks against hacking threats
As we saw during the 2016 US election, protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science. Now consider the complex world of quantum computing, where bits of information can simultaneously hold multiple states beyond zero and one, and the potential threats become even trickier to tackle. Researchers have uncovered clues that could help administ.. "
