Good news, everyone!

For many years, I lived in the Indian city of Chennai, where the summer temperatures can reach up to 44° C. With a population of 4.5 million, this coastal city is humid and hot.

Sometimes to truly study something up close, you have to take a step back. That's what Andrea Donnellan does. An expert in Earth sciences and seismology, she gets much of her data from a bird's-eye view, studying the planet's surface from the air and space, using the data to make discoveries and deepen understanding about earthquakes and other geological processes.

Fluorophores are chemical compounds or molecules that absorb light energy at one wavelength and re-emit it as light at a longer, lower-energy wavelength, acting as glowing tags or markers. The absorption process is known as excitation, and the re-emission is visible as fluorescent light, which makes these molecules crucial for biological imaging, diagnostics, and tracing cellular molecules like proteins or lipids under normal or various infectious conditions.

Genetic disorders occur due to alterations in the primary genetic material—deoxyribonucleic acid (DNA)—of an organism.

Researchers at Kumamoto University have discovered that a purely inorganic crystal grown from water solution can emit circularly polarized light, a special form of light whose "handedness" distinguishes left from right.

When energy researchers talk about the future of the grid, they often focus on individual pieces: solar panels, batteries, nuclear plants, or new transmission lines. But in a recent study, urban systems researcher Anton Rozhkov takes a different approach—treating the energy system itself as a complex, evolving organism shaped as much by policy and human behavior as by technology.

When the four-member crew of Axiom-2 launched into space in May 2023, their 10-day mission was chock full of experiments aimed at understanding human physiology. Results from some of those experiments, now online at Aging Cell, highlight spaceflight as a unique model for studying aging as well as cellular resilience. The research sets the stage for testing potential anti-aging interventions for those of us who have no plans to travel in space.

Plants make substances called alkaloids to protect themselves, and humans have long taken advantage of these chemicals, using them in painkillers, treatments for disease and household products such as caffeine and nicotine.

As with humans, the maternal bond in nature is important for animals to find their way in the world. In mammals, a mother does not just provide milk; she also teaches her offspring survival skills and how to play well with others. But according to new research into domestic horses published in the journal Nature Communications, staying with mom fundamentally changes the developing brain and body of foals.

How much fresh water is in the United States? It's a tough question, since most of the water is underground, accessible at varying depths. In previous decades, it's been answered indirectly from data on rainfall and evaporation. Knowing how much groundwater is available at specific locations is critical to meeting the challenges of water scarcity and contamination.

Australia's iconic red landscapes have been home to Aboriginal culture and recorded in songlines for tens of thousands of years. But further clues to just how ancient this landscape is come from far beyond Earth: cosmic rays that leave telltale fingerprints inside minerals at Earth's surface.

Approximately 20% to 30% of all people who suffer from psoriasis also develop painful inflammation in their joints over time. If left untreated, this condition known as psoriatic arthritis can lead to permanent damage to bones and joints. Until now, it was a mystery why the disease progressed this way in some patients and not in others.

If trucks ran on hydrogen instead of fossil fuels, carbon dioxide emissions from heavy-duty road transport could be significantly reduced. At the same time, a new study from Chalmers University of Technology in Sweden shows that differences in how the gas is produced, distributed and used greatly affect its climate benefits.

Converting the vibrations generated by water currents in contact with an object into energy. This is the basis of the new system designed by Francisco Huera, a researcher in the Department of Mechanical Engineering at the Universitat Rovira i Virgili (URV). The device harnesses the energy of water currents from the vibrations that occur when water passes around a cylinder and creates vortices behind it. This method has a very simple structure: a submerged cylindrical tube hanging from an axis that oscillates like a pendulum when the water current makes it vibrate.
