“Simulation Hypothesis” has leaped into quantum lab experiments

Posted by in categories: computing, quantum physics

Have you ever considered the possibility that our reality might be an intricately crafted computer simulation? There is a name for this theory — Simulation Hypothesis — and it is now being tested in quantum lab experiments.

Though it may initially resemble a plot from the latest sci-fi blockbuster, a dedicated group of researchers is rigorously exploring this intriguing concept.

They are investigating the philosophical implications and technological advancements that could render such a simulation plausible.

Can quantum particles mimic gravitational waves?

Posted by in categories: cosmology, particle physics, quantum physics

When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (LIGO) telescope in September 2015.

Predicting the effect of binding molecules on the shape and mechanical properties of structured DNA assemblies

Posted by in categories: biotech/medical, computing

Chemo-mechanical deformation of structured DNA assemblies driven by DNA-binding ligands is promising for biological and therapeutic applications, but it is elusive how to effectively model and predict their effects on the deformation and mechanical properties of DNA structures. Here, the authors present a computational framework for simulating chemo-mechanical change of structured DNA assemblies, using ethidium bromide intercalation as an example.
