Quantum physics in a leaf? Scientists discover the link between photosynthesis and the fifth state of matter

Abstract photosynthesis

Scientists discovered that natural photosynthesis has similar characteristics to condensed exciton, a frictionless energy state that typically requires extremely low temperatures. This insight can improve the design of the technology, potentially doubling energy efficiency. The UChicago researchers hope that exciton condensation islands could pave the way for new discoveries. Inside a laboratory, scientists marvel at … Read more

Discrepancy in dark matter: a cosmic conundrum in the standard cosmological model

Abstract astrophysics Dark matter cosmology

An international team of astrophysicists and cosmologists has presented five papers suggesting that the aggregate (S8 value) of the universe’s dark matter is 0.76, a figure that lines up with other gravitational lensing surveys but not with the 0 value. 83 derived from the Cosmic Microwave Background. An international team of scientists used advanced techniques … Read more

Next-generation gravitational-wave detectors could pinpoint dark matter

Predicted upper bounds at the 90th percentile on stochastic DM signals from LIGO, LISA, GQuEST and Holometer, assuming T = 1 year of observation time and local DM density DM = 0.46 GeV/c2/cm3. The limits are derived by setting the 10th percentile SNR defined in Eq. (43) be two. Credit: arXiv (2023). DOI: 10.48550/arxiv.2306.13122 Gravitational … Read more

Next-generation gravitational-wave detectors could pinpoint dark matter

Universe Today

Gravitational astronomy is a relatively new discipline that has opened many doors for astronomers to understand how the huge, violent end of the scale works. It has been used to map merging black holes and other extreme events across the universe. Now a team at Cal Tech’s Walter Burke Institute for Theoretical Physics thinks they … Read more

Dark matter could interact in totally unexpected ways with the universe

Universe Today

According to Sir Isaac Newton’s theory of universal gravitation, gravity is an action at a distance, where one object feels the influence of another regardless of distance. This became a central feature of classical Newtonian physics which remained the accepted canon for over two hundred years. In the 20th century, Einstein began reconceptualizing gravity with … Read more

Decoding nuclear matter: A two-dimensional solution unlocks the secrets of neutron stars

Quarks line up in dense nuclear matter

From United States Department of Energy June 29, 2023 In dense nuclear matter, quarks line up, becoming essentially one-dimensional. Calculations considering a single dimension plus time can track how low-energy excitations propagate through nuclear matter. Credit: Brookhaven National Laboratory Brookhaven National Laboratory scientists have used two-dimensional condensed matter physics to understand the interactions of quarks … Read more

Quadruple Shot: Unraveling the mysteries of dark matter with a multiple-image gravitational lensing supernova

Zoom in on Supernova Zwicky

Zwicky supernova zoom: starting with a small portion of the Palomar ZTF camera, one of 64 quadrants, each of which contain tens of thousands of stars and galaxies, the zoom takes us to detailed explorations carried out with the largest and sharpest VLT and Keck telescopes in Chile and Hawaii, respectively. In the better resolved … Read more

Decoding dark matter and energy: what you need to know about the Euclid mission launching this weekend

The Euclid telescope has a launch date scheduled for Saturday, July 1.

Together, dark matter and dark energy make up 95% of the known universe, yet scientists do not know what they are. The Euclid telescope, set to be launched into space from Florida on Saturday, could help decipher them. First color images from the Webb Space Telescope Here’s what you need to know about the world’s … Read more
