In a groundbreaking announcement, physicists from University College London (UCL) have presented a radical theory that unifies the realms of gravity and quantum mechanics while preserving the classical concept of spacetime, as outlined by Einstein.
This innovative approach, detailed in two simultaneously published papers, challenges over a century of scientific consensus and proposes a revolutionary perspective on the fundamental nature of our universe.
Modern physics rests on two contradictory pillars: quantum theory, which rules the microscopic world, and Einstein’s theory of general relativity, explaining gravity through spacetime curvature. These theories, despite their individual successes, have remained irreconcilable, creating a significant rift in our understanding of the universe.
A breakthrough in nanofluidics is set to revolutionize our grasp of molecular dynamics at minuscule scales. Collaborative efforts from scientists at EPFL and the University of Manchester have uncovered a previously hidden world by using the newly found fluorescent properties of a graphene-like 2D material, boron nitride. This innovative approach enables scientists to track individual molecules within nanofluidic structures, illuminating their behavior in ways never before possible. The study’s findings were recently published in the journal Nature Materials.
Nanofluidics, the study of fluids confined within ultra-small spaces, offers insights into the behavior of liquids on a nanometer scale. However, exploring the movement of individual molecules in such confined environments has been challenging due to the limitations of conventional microscopy techniques. This obstacle prevented real-time sensing and imaging, leaving significant gaps in our knowledge of molecular properties in confinement.
In the age of rapid technological advancements, a new player has emerged on the scene, promising to revolutionize the way we transmit data wirelessly. Li-Fi, or Light Fidelity, is a cutting-edge technology that employs visible light to transmit information, offering an innovative alternative to traditional radio frequency-based wireless communication systems.
The IEEE published the 802.11bb standard for light-based networking in July 2023, an extension of the Wi-Fi specification enabling wireless networking using visible and infrared light rather than the radio spectrum. The standard outlines adjustments to the physical and medium access control layers, allowing wireless networking through light source modulation imperceptible to the human eye.
The Li-Fi specification mandates bidirectional transmission within the 800nm to 1,000nm electromagnetic spectrum range, ensuring a minimum throughput of 10 Mb/s and a maximum of 9.6 Gb/s at the MAC data service access point. By comparison, Wi-Fi operates within wavelengths of 120mm (2.4 GHz) and 60mm (5 GHz), with speeds that vary across versions, including Wi-Fi 6, which reaches up to 9.6 Gb/s, akin to Li-Fi capabilities.
