Highly polar pesticides such as glyphosate are notoriously difficult to detect in food due to their chemical properties and interference from natural food compounds. A new method developed by Dr Michelangelo Anastassiades and Ann‑Kathrin Schäfer of CVUA Stuttgart, and their colleagues, offers a more accurate and practical way to identify residues of these pesticides. By simplifying sample preparation and reducing interference, the method delivers reliable results across a wide range of foods. This development improves routine food safety testing and strengthens our ability to monitor potentially harmful pesticides.

For over a century, Einstein’s theory of general relativity has underpinned our understanding of gravity. However, it still hasn’t been able to explain some of the most enduring mysteries in cosmology, including the need for vast quantities of dark matter, which has gone undetected for decades. Today, this need has been explained by Conformal Gravity: a framework which modifies Einstein’s theory by requiring that the laws of physics must stay the same, even if all fields are scaled up or down at every point in space and time. Through his research, Robert Nesbet of IBM’s Almaden Research Center argues that this principle – named ‘universal conformal symmetry’ – should apply to all fundamental fields. If correct, this framework could eliminate the need for dark matter and dark energy.

Scientific discovery often unfolds in unexpected ways. What begins as a search for solutions to real-world challenges can lead researchers into unexplored scientific territory, where unconventional ideas emerge and spark debate. This dynamic was at the heart of research by Dr. Arthur W. Snow and Dr. Ramagopal Ananth in the Chemistry Division of the US Naval Research Laboratory. Their study aimed to address a pressing need: replacing fluorocarbon surfactants in firefighting foams. What they discovered would take them beyond firefighting applications and into fundamental questions about the nature of water itself.

Sitting directly over a complex network of fault lines, Haiti is one of the most earthquake-prone nations on Earth. In 2021, the Nippes earthquake became the latest to devastate the country, and today, researchers are still piecing together the timeline of seismic events which unfolded during the earthquake. Through their research, Professor Jeremy Maurer and colleagues at Missouri University of Science and Technology have described how the Nippes earthquake originated, shifted, and ruptured a major fault line, triggering numerous ‘afterslip’ events in the following days.

Before the universe was illuminated by stars, most of its observable matter existed in a roughly even distribution of hydrogen and helium. As these materials collapsed under their own gravity, they would have heated up, initially preventing them from collapsing further to densities high enough for stars to form. As part of a new review, Prof. Dr. Ralf Klessen and Prof. Dr. Simon Glover at Heidelberg University investigate the chemical mechanisms which enabled this primordial gas to cool and fragment to form the universe’s first generation of stars.

The Sichuan basin in southern China is a region of deep geological and seismological complexity, which has so far prevented researchers from understanding its tectonic past. Through fresh analysis of previous observations, combined with the latest modelling techniques, a team led by Dr. Zhe Su at the National Institute of Natural Hazards, Beijing, suggests for the first time that the entire Sichuan basin is slowly rotating. Their result could explain the origins of one of the deadliest earthquakes in living memory, and could also help seismologists to better predict when earthquakes will strike the region in the future.
