Is Saturn’s ocean moon Enceladus habitable? This is what a recent study published in The Planetary Science Journal hopes to address as a team of scientists investigated the likelihood of Enceladus hosting the necessary ingredients for life as we know it. This study has the potential to help scientists develop new methods for finding life beyond Earth, even life as we don’t know it.
For the study, the researchers examined whether Raman spectroscopy, which is a common chemical analysis method in planetary science, could be used to analyze particles emitted from Enceladus’ plumes. These plumes, which originate from Enceladus’ south polar region, are responsible for discharging pieces of the moon’s interior ocean, including water vapor and other molecules. To accomplish this, the researchers used a vacuum chamber to simulate conditions on Enceladus and froze salt water at pH levels of 9 and 11. They then analyzed the salts using Raman spectroscopy to ascertain if it could identify particles within the water and determine which pH level they originated from.
In the end, the researchers discovered that the instrument could differentiate between the two pH levels while identifying sodium bicarbonate (baking soda) and sodium carbonate (washing soda) in both pH levels while identifying only sodium bicarbonate (baking soda) in pH 11. The researchers note these findings demonstrate the potential for using a spacecraft-mounted Raman spectrometer for future missions to Enceladus and other icy worlds with the goal of identifying the necessary ingredients for life as we know it.
Researchers have demonstrated a superconducting quantum circuit that simulates tunneling in chemical reactions, revealing unexpected quantum effects in state transitions.
The work enables controlled study of quantum dynamics in chemistry-like energy landscapes and highlights superconducting circuits as powerful tools for exploring chemical processes.

A quiet revolution is underway in modern medicine: Drug development is aiming to move from managing disease to correcting it through RNA and gene-editing therapies. But delivering these treatments safely and precisely to the right cells remains a major hurdle—especially in hard-to-target organs like the brain and kidneys.
Now, researchers led by a University of Ottawa Faculty of Medicine team offer highly compelling evidence that an elegant, nature-inspired solution lies in ultra-tiny, bubble-like structures called small extracellular vesicles (sEVs). These metabolic messengers, refined over millions of years of evolution, carry RNA—a nucleic acid that is a chemical cousin of DNA—and other molecules between cells.
In a nutshell, the research team’s new findings show that not all sEVs are alike: their cell of origin determines where they travel, with certain vesicles naturally targeting specific tissues in the body.
Researchers in the University of Minnesota Twin Cities have discovered a powerful new way to control the electronic behavior of a metal—by manipulating the atomic properties of materials where they meet. The study, published in Nature Communications, demonstrates that interfacial polarization can tune the surface work function of metallic ruthenium dioxide (RuO2) by more than 1 electron volt (eV)—a tiny amount of energy—simply by adjusting film thickness at the nanometer scale.
“We often think of polarization as something that belongs to insulators or ferroelectrics—not metals,” said Bharat Jalan, professor and Shell Chair in the Department of Chemical Engineering and Materials Science at the University of Minnesota. “Our work shows that, through careful interface design, you can stabilize polarization in a metallic system and use it as a knob to tune electronic properties. This opens an entirely new way of thinking about controlling metals.”
This specific change is most powerful when the metal layer is about 4 nanometers thick—roughly the width of a single strand of DNA. At this precise size, the metal shifts from being “stretched” by the material underneath it to a more “relaxed” state. This transition proves that the physical way atoms are packed together has a direct, measurable impact on how the metal handles electricity.
Researchers at Clarkson University have reported a breakthrough in tackling per- and polyfluoroalkyl substances (PFAS), a group of widely used “forever chemicals” that are difficult to remove from water and have raised growing environmental and public health concerns. The study, published in Nature Communications, was led by Associate Professor Yang Yang and his team in the Department of Civil and Environmental Engineering. It presents a new method for breaking down PFAS that could improve the treatment of contaminated water in real-world conditions.
As global demand for lithium-ion batteries continues to surge, a team of Rice University researchers has developed a faster, more energy-efficient way to recover critical minerals from spent batteries, potentially easing supply chain pressures and reducing environmental harm.
In a new study published in Small, researchers from Rice’s Department of Materials Science and Nanoengineering introduce a class of water-based solutions that can extract valuable metals from battery waste in minutes rather than hours. The work centers on aqueous solutions of amino chlorides, which mimic the performance of commonly studied green solvents like deep eutectics, while avoiding their key limitations.
“Traditional recycling methods often rely on harsh acids or slow, energy-intensive processes,” said the study’s first author, Simon M. King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute. “What we’ve shown is that you can achieve rapid, high-efficiency metal recovery using a much simpler, water-based system.”

Mars may look like a quiet, dusty world, but it’s actually buzzing with hidden electrical activity. Powerful dust storms and swirling dust devils generate static electricity strong enough to spark faint glowing discharges across the planet, triggering chemical reactions that reshape its surface and atmosphere. Scientists have now shown that these tiny lightning-like events can create a surprising mix of chemicals—including chlorine compounds and carbonates—and even leave behind distinct isotopic “fingerprints.”
Mars is often portrayed as a dry, lifeless desert, but it is far more active than it appears. Its thin atmosphere and dusty terrain create an environment where constant motion generates electrical energy. Dust storms and spinning dust devils sweep across the surface, continually reshaping the landscape and driving processes that scientists are only beginning to fully understand.
Planetary scientist Alian Wang has been studying this phenomenon in depth. In a series of studies, including recent work published in Earth and Planetary Science Letters, she has examined how these electrically charged dust activities influence the chemistry of Mars, particularly through their impact on isotopes.
