Published Management zone maps of little use to corn growers



A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study found that -- contrary to common assumptions -- crop-plot responses to the same inputs vary significantly from year to year. The most unpredictable factor -- the weather -- seemed to have the biggest impact on how the crops responded to these inputs.
Published How weather phenomena affect ocean circulation



A new study has investigated how future changes in weather patterns could affect the tropical Pacific Ocean and its ecosystems. The research, based on complex computer models, has shown that these changes will have far-reaching consequences for ocean circulation. The authors stress the need to take this more into account in future climate models.
Published Simulations of 'backwards time travel' can improve scientific experiments



Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.
Published The fuel economy of a microswimmer



The amount of power a microswimmer needs to move can now be determined more easily. Scientists developed a general theorem to calculate the minimal energy required for propulsion. These insights allow a profound understanding for practical applications, such as targeted transport of molecules and substrates.
Published Surprising discovery shows electron beam radiation can repair nanostructures



In a surprising new study, researchers have found that the electron beam radiation that they previously thought degraded crystals can actually repair cracks in these nanostructures. The groundbreaking discovery provides a new pathway to create more perfect crystal nanostructures, a process that is critical to improving the efficiency and cost-effectiveness of materials that are used in virtually all electronic devices we use every day.
Published Experts warn of risk of civil unrest in UK due to food shortages



Food shortages caused by extreme weather could lead to civil unrest in the UK, according to a new study which has surveyed some of the country’s leading food experts.
Published Widely tuneable terahertz lasers boost photo-induced superconductivity in K3C60



Researchers have long been exploring the effect of using tailored laser drives to manipulate the properties of quantum materials away from equilibrium. One of the most striking demonstrations of these physics has been in unconventional superconductors, where signatures of enhanced electronic coherences and super-transport have been documented in the resulting non-equilibrium states. However, these phenomena have not yet been systematically studied or optimized, primarily due to the complexity of the experiments. Technological applications are therefore still far removed from reality. In a recent experiment, this same group of researchers discovered a far more efficient way to create a previously observed metastable, superconducting-like state in K3C60 using laser light.
Published Scientists discover 'flipping' layers in heterostructures to cause changes in their properties



Transition metal dichalcogenide (TMD) semiconductors are special materials that have long fascinated researchers with their unique properties. For one, they are flat, one-atom-thick two-dimensional (2D) materials similar to that of graphene. They are compounds that contain different combinations of the transition metal group (e.g., molybdenum, tungsten) and chalcogen elements (e.g., sulfur, selenium, tellurium).
Published Rivers may not recover from drought for years



Lack of rainfall is not the only measure of drought. New research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years.
Published Warm summers and wet winters yield better wine vintages



Wine quality is notorious for varying from year to year, but what makes for a 'good year?' Researchers show that weather plays an important role in determining wine quality. By analyzing 50 years’ worth of wine critic scores from the Bordeaux wine region in relation to that year’s weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.
Published Experiencing record-breaking heat days affects perception of weather trends



Research finds that experiencing days in which the temperature exceeds previous highs for that time of year affects people’s perception of weather trends.
Published Bringing out the color in zinc



Researchers have synthesized a zinc complex based on two zinc centers that absorbs visible light. They demonstrated that this capability depends on the proximity of the zinc ions, where the complex responds to visible light when the zinc atoms are closer. This new property is expected to expand the utility of zinc, which already offers advantages including biological relevance, cost effectiveness, and low toxicity.
Published Paleoclimatologists use ancient sediment to explore future climate in Africa



With global warming apparently here to stay, a team of paleoclimatologists are studying an ancient source to determine future rainfall and drought patterns: fossilized plants that lived on Earth millions of years ago.
Published X-rays reveal microstructural fingerprints of 3D-printed alloy



Researchers took a novel approach to explore the way microstructure emerges in a 3D-printed metal alloy: They bombarded it with X-rays while the material was being printed.
Published Unifying matter, energy and consciousness



Understanding the interplay between consciousness, energy and matter could bring important insights to our fundamental understanding of reality.
Published Ionic crystal generates molecular ions upon positron irradiation, finds new study



The interaction between solid matter and positron (the antiparticle of electron) has provided important insights across a variety of disciplines, including atomic physics, materials science, elementary particle physics, and medicine. However, the experimental generation of positronic compounds by bombardment of positrons onto surfaces has proved challenging. In a new study, researchers detect molecular ion desorption from the surface of an ionic crystal when bombarded with positrons and propose a model based on positronic compound generation to explain their results.
Published Researchers identify largest ever solar storm in ancient 14,300-year-old tree rings



An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps. The radiocarbon spike was caused by a massive solar storm, the biggest ever identified. A similar solar storm today would be catastrophic for modern technological society – potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions. The academics are warning of the importance of understanding such storms to protect our global communications and energy infrastructure for the future.
Published The Gulf Stream is warming and shifting closer to shore



The Gulf Stream is intrinsic to the global climate system, bringing warm waters from the Caribbean up the East Coast of the United States. As it flows along the coast and then across the Atlantic Ocean, this powerful ocean current influences weather patterns and storms, and it carries heat from the tropics to higher latitudes as part of the Atlantic Meridional Overturning Circulation. A new study now documents that over the past 20 years, the Gulf Stream has warmed faster than the global ocean as a whole and has shifted towards the coast. The study relies on over 25,000 temperature and salinity profiles collected between 2001 and 2023.
Published Climate-driven extreme heat may make parts of Earth too hot for humans



If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves, according to interdisciplinary research. Results indicated that warming of the planet beyond 1.5 C above preindustrial levels will be increasingly devastating for human health across the planet.
Published Climate change brings earlier arrival of intense hurricanes



New research has revealed that since the 1980s, Category 4 and 5 hurricanes (maximum wind speed greater than 131 miles per hour) have been arriving three to four days earlier with each passing decade of climate change.
