In recent decades, researchers have developed advanced techniques to detect and manipulate individual photons. A particularly intriguing field examines how nanoscale light emitters, resembling artificial atoms, produce these photons. In this vein, a new study addresses a subtle question: when two such emitters release photons that are red-shifted due to energy loss, do these photons […]

Author: Gerlinde Bigga, Scientific Coordinator of the Leibniz Science Campus “Geogenomic Archaeology Campus Tübingen”, University of Tübingen The last two decades have seen a revolution in scientists’ ability to reconstruct the past. This has been made possible through technological advances in the way DNA is extracted from ancient bones and analysed. These advances have revealed […]
In September 2023, NASA’s OSIRIS-REx spacecraft brought home a remarkable gift: the first pristine sample ever collected from a carbon-rich asteroid called Bennu. After two years of careful study in laboratories worldwide, scientists have confirmed that Bennu’s dust and pebbles contain many of the very same small molecules life on Earth relies on as its […]
Can a father’s lifestyle choices before conception influence the health of his future children? New research reveals that environmental factors affecting fathers can leave molecular footprints in embryos, shaping development and potentially impacting long-term health. Epigenetic inheritance For decades, scientists believed that inheritance was controlled exclusively by DNA sequences passed from parents to offspring. Today […]

In the layered kagome metal CsV₃Sb₅, researchers have observed something that, until now, seemed almost impossible: robust quantum interference in the normal, non-superconducting state, persisting over distances of several micrometers. The interference is not the fragile single-particle kind seen in ultra-clean semiconductors at millikelvin temperatures. Instead, it behaves as if the entire stack of kagome […]
Author: Knut von Salzen, Senior Research Scientist, Marine Cloud Brightening Research Program, University of Washington Winter is setting in across the Northern Hemisphere, and with it, cold and cloudy winter days. Clouds play a vital role in the environment, providing rain but also reflecting sunlight before it reaches the Earth’s surface. But between 2003 and […]
There’s always a touch of melancholy when a chapter that has absorbed years of work comes to an end. In the case of the Atacama Cosmology Telescope (ACT), those years amount to nearly 20—and now the telescope has completed its mission. Yet some endings are also important beginnings, opening new paths for the entire scientific […]
In the our last entry, we saw the weakness of Gabriel’s ‘inism’ (the belief that to exist has to be identical to ‘exist in something’) as the most important logical fault of his ontology. We also saw that his idea that ‘the world’ (in the sense of a super-entity comprising the totality of real beings) […]

When we think of atoms sitting on a surface, we tend to imagine them as fairly still, especially at very low temperatures (colder than liquid nitrogen, in fact). Yet in modern surface science we often discover the opposite: atoms can be surprisingly restless, gliding from place to place in ways that shape how materials grow […]
