Ultrafast probing reveals intricate dynamics of quantum coherence

Posted · Add Comment

Ultrafast, multidimensional spectroscopy unlocks macroscopic-scale effects of quantum electronic correlations. Researchers found that low-energy and high energy states are correlated in a layered, superconducting material. Exciting the material with an ultrafast beam of near-infrared light produces coherent excitations lasting a surprisingly ‘long’ time of around 500 femtoseconds, originating from a quantum superposition of excited states […]

Novel coronavirus (COVID-19) imaging features overlap with SARS and MERS

Posted · Add Comment

Although COVID-19’s imaging features are variable and nonspecific, the findings thus far do show ”significant overlap” with those of severe acute respiratory syndrome and Middle East respiratory syndrome. The early evidence suggests that initial chest imaging will show abnormality in at least 85% of patients, with 75% of patients having bilateral lung involvement initially that […]

Hunter-gatherer networks accelerated human evolution

Posted · Add Comment

Humans began developing a complex culture as early as the Stone Age. This development was brought about by social interactions between various groups of hunters and gatherers, a new study has now confirmed. The researchers mapped the social networks of present-day hunter-gatherers in the Philippines and simulated the discovery of a medicinal plant product.

Betelgeuse: A massive star’s dying breaths

Posted · Add Comment

Betelgeuse has been the center of significant media attention lately. The red supergiant is nearing the end of its life, and when a star over 10 times the mass of the Sun dies, it goes out in spectacular fashion. With its brightness recently dipping to the lowest point in the last hundred years, many space […]
