Scientists have discovered a new four-body quasi-particle, the quadruplon, in a 2D semiconductor. Using laser experiments and advanced theory, they identified unique spectral features unexplained by existing models, confirming the quadruplon’s existence. A central goal of physics is to understand

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between ‘then’ and ‘now’

Down at the quantum scale of buzzing electrons, however, ‘then’ can’t always be anticipated. Worse still, ‘now’ often blurs into a haze of vagueness. A stopwatch simply isn’t going to work for some scenarios.

A potential solution could be found in the very shape of the quantum fog itself, according to a 2022 study by researchers from Uppsala University in Sweden.

In their study, published in Mechanobiology in Medicine, the researchers discovered that the protein responsible for binding neural stem cells in the human brain, neuro-cadherin, also plays a key role in stimulating their differentiation.

Neural stem cells are early-stage, unspecialized cells that have the ability to differentiate, or develop, into various types of neurons and non-neuronal cells of the central nervous system.
