Between 1982 and 2012, the 150-foot solar tower at Mount Wilson Observatory collected a vast archive of observations of the Sun’s surface. In a series of recent studies, Professor Roger Ulrich, together with colleagues Dr. Tham Tran and Dr. John Boyden at UCLA, have revisited these data, running a thorough recalibration of the findings. Their results led them to a crucial discovery: two properties of the Sun’s plasma which were once thought to be separate are actually two faces of the same underlying effect, which plays a fundamental role in shaping the Sun’s magnetic field throughout the solar cycle.

Building the next generation of particle accelerators depends on solving surprisingly small but stubborn material-related problems. Dr Jerzy Lorkiewicz and his collaborators of the National Centre for Nuclear Research in Poland tackled one of the toughest challenges: how to make lead films stick firmly to niobium, to realise his vision of a fully superconducting electron injector. By implanting lead ions into the niobium before adding a lead layer, his team created a smoother, more durable bond that resisted peeling. This innovation brings us closer to more efficient electron injectors for powerful particle accelerators.

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.

Data involving angles can be found across a diverse array of scientific fields, but so far, the mathematical tools used to study them have often proved insufficient to detect the complex relationships between different angles within large datasets. Through its research, a team consisting of Professor Christophe Ley and Sophia Loizidou from the University of Luxembourg, Professor Shogo Kato from the Institute of Statistical Mathematics in Tokyo, and Professor Kanti Mardia from the University of Leeds, has developed a new model which overcomes many of these challenges: allowing the researchers to study relationships between three angles at once, as well as mixtures of angles and classical measurements on the line.

For decades, works of science fiction have explored how the universe’s most fundamental speed limit could be broken by warping the fabric of spacetime. Through his experiments, Dr. Chance Glenn, founder of Morningbird Space Corporation, believes he may have discovered how spacetime can be distorted by extreme electric fields, which can be easily created in the lab. If his theory is correct, it would mean that the concept of ‘warp drives’ which allow us to travel at faster than the speed of light could be more feasible than we once thought.
