Scientists discover single atom defect in 2D material can hold quantum information at room temperature

Scientists have discovered that a “single atomic defect” in a layered 2D material can hold onto quantum information for microseconds at room temperature, underscoring the potential of 2D materials in advancing quantum technologies.

The defect, found by researchers from the Universities of Manchester and Cambridge using a thin material called (hBN), demonstrates spin coherence—a property where an electronic spin can retain —under ambient conditions. They also found that these spins can be controlled with light.

Up until now, only a few have been able to do this, marking a significant step forward in quantum technologies.

NA64 uses the high-energy SPS muon beam to search for dark matter

The NA64 experiment started operations at CERN’s SPS North Area in 2016. Its aim is to search for unknown particles from a hypothetical “dark sector.” For these searches, NA64 directs an electron beam onto a fixed target. Researchers then look for unknown dark sector particles produced by collisions between the beam’s electrons and the target’s atomic nuclei.

Iso-propagation vortices: Optical multiplexing for unprecedented information capacity

The future of optical communications just got brighter. In a development reported in Advanced Photonics, researchers from Nanjing University have introduced iso-propagation vortices (IPVs), a novel concept that offers a solution to a long-standing challenge faced by scientists and engineers: how to increase information processing capacity while overcoming the limitations of traditional vortex beams.

Seeing the color of entangled photons in molecular systems

Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way particles of light called photons interact with matter. These classical spectroscopy techniques include one-photon absorption (OPA) and two-photon absorption (TPA).

Expanding on the fundamental principles of liquid movement

From the rain drops rolling down your window, to the fluid running through a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces is a heavily researched subject, where new discoveries can have profound effects in the fields of energy conversion technology, electronics cooling, biosensors, and micro-/nano-fabrications.

Beautiful and Charming: Physicists Discover a New Tetraquark

A new study unveils the existence of a tetraquark composed of beauty and charm quarks, advancing our knowledge of subatomic particle physics and strong force interactions.

Exploring the complex domain of subatomic particles, researchers at The Institute of Mathematical Science (IMSc) and the Tata Institute of Fundamental Research (TIFR) have recently published a novel finding in the journal Physical Review Letters. Their study illuminates a new horizon within Quantum Chromodynamics (QCD), shedding light on exotic subatomic particles and pushing the boundaries of our understanding of the strong force.

Darwin Revisited: Modern Data Sheds Light on Ancient Evolutionary Theories

Ever since Darwin introduced his groundbreaking theory of evolution, biologists have been captivated by the complex processes that enable species to evolve.

Can mechanisms responsible for the evolution of a species over a few generations, called microevolution, also explain how species evolve over periods of time extending to thousands or millions of generations, also called macroevolution?

A new paper, just published in Science, shows that the ability of populations to evolve and adapt over a few generations, called evolvability, effectively helps us understand how evolution works on much longer timescales.

When Nightmares Turn Real: Sleep’s Early Warning Signs of Autoimmune Disease

Nightmares and hallucinations could be early signs of autoimmune diseases like lupus, potentially improving early diagnosis and treatment, according to a new study.

An increase in nightmares and hallucinations – or ‘daymares’ – could indicate the beginning of autoimmune diseases such as lupus. This is according to an international team led by researchers at the University of Cambridge and King’s College London.

They emphasize the importance of recognizing these mental health and neurological symptoms as early warning signs of an impending ‘flare,’ a phase during which the disease intensifies temporarily.
