Solid electrolyte’s unique atomic structure helps next-generation batteries keep their cool

A team of UC Riverside engineers has discovered why a key solid-state battery material stays remarkably cool during operation—a breakthrough that could help make the next generation of lithium batteries safer and more powerful.

The study, published in PRX Energy, focused on a known as LLZTO—short for lithium lanthanum zirconium tantalum oxide. The substance is a promising solid electrolyte for solid-state , which could deliver higher energy density than today’s lithium-ion batteries while reducing overheating and fire risks.

The study’s title is “Origin of Intrinsically Low Thermal Conductivity in a Garnet-Type Solid Electrolyte: Linking Lattice and Ionic Dynamics with Thermal Transport.”

Saturday Citations: Yet another solution for universal expansion; computing with brain organoids

This week, researchers reported the discovery of four Late Bronze Age stone megastructures likely used for trapping herds of wild animals. Physicists have proven that a central law of thermodynamics does not apply to atomic-scale objects that are linked via quantum correlation. And two Australian Ph.D. students coded a software solution for the James Webb Space Telescope’s Aperture Masking Interferometer, which has been producing blurry images.

Additionally, researchers are networking tiny human brain organoids into a computing substrate; have proposed that environmental lead exposure may have influenced early human brain evolution; and physicists have provided a to explain accelerating universal expansion without :

Governor-General’s Design Challenge 2025

Are you keen to explore quantum concepts with your students? Have you been looking for ideas on how to make abstract ideas more accessible and engaging for young learners?

The 2025 Governor-General’s Design Challenge celebrates the Year of Quantum Science and Technology by supporting you to turn your students into “photon detectives” in the classroom.

This hands-on STEM experience for students in Years 5–10 sets out a challenge for your class to complete, with the challenge introduced in a special video co-presented by the Governor-General, Her Excellency the Honourable Sam Mostyn AC and Questacon.

Nanoparticle blueprints reveal path to smarter medicines

Lipid nanoparticles (LNPs) are the delivery vehicles of modern medicine, carrying cancer drugs, gene therapies and vaccines into cells. Until recently, many scientists assumed that all LNPs followed more or less the same blueprint, like a fleet of trucks built from the same design.

Now, in Nature Biotechnology, researchers from the University of Pennsylvania, Brookhaven National Laboratory and Waters Corporation have characterized the shape and structure of LNPs in unprecedented detail, revealing that the particles come in a surprising variety of configurations.

That variety isn’t just cosmetic: As the researchers found, a particle’s internal shape and structure correlates with how well it delivers therapeutic cargo to a particular destination.

‘Messy’ galaxies in the early universe struggled to settle, Webb reveals

Astronomers using the James Webb Space Telescope (JWST) have captured the most detailed look yet at how galaxies formed just a few hundred million years after the Big Bang—and found they were far more chaotic and messy than those we see today.

The team, led by researchers at the University of Cambridge, analyzed more than 250 young galaxies that existed when the universe was between 800 million and 1.5 billion years old. By studying the movement of gas within these galaxies, the researchers discovered that most were turbulent, “clumpy” systems that had not yet settled into smooth rotating disks like our own Milky Way.

Their findings, published in Monthly Notices of the Royal Astronomical Society, suggest that galaxies gradually became calmer and more ordered as the universe evolved. But in the , star formation and gravitational instabilities stirred up so much turbulence that many galaxies struggled to settle.

Algorithm maps genetic connection between Alzheimer’s and specific neurons

The number of people living with dementia worldwide was estimated at 57 million in 2021 with nearly 10 million new cases recorded each year. In the U.S., dementia impacts more than 6 million lives, and the number of new cases is expected to double over the next few decades, according to a 2025 study. Despite advancements in the field, a full understanding of disease-causing mechanisms is still lacking.

To address this gap, Rice University researchers and collaborators at Boston University have developed a that can help identify which specific types of cells in the body are genetically linked to complex human traits and diseases, including in forms of dementia such as Alzheimer’s and Parkinson’s.

Known as “Single-cell Expression Integration System for Mapping genetically implicated Cell types,” or seismic, the tool helped the team hone in on genetic vulnerabilities in memory-making brain cells that link them to Alzheimer’s ⎯ the first to establish an association based on a genetic link between the disease and these specific neurons. The algorithm outperforms existing tools for identifying that are potentially relevant in complex diseases and is applicable in disease contexts beyond dementia.

Geochemical research could help identify microbial activity in Earth’s rock record and perhaps in Martian sediments

Because oxygen-bearing sulfate minerals trap and preserve signals from Earth’s atmosphere, scientists closely study how they form. Sulfates are stable over billions of years, so their oxygen isotopes are seen as a time capsule, reflecting atmospheric conditions while they were evolving on early Earth—and possibly on its planetary neighbor Mars.

A new study led by a University of Utah geochemist examines how forms when pyrite, commonly known as “fool’s gold,” is oxidized in environments teeming with microbes versus those without them. The researchers focused on Spain’s Rio Tinto, a contaminated river passing through a region where iron and copper were mined for thousands of years.

The paper titled, “Triple-oxygen isotopic evidence of prolonged direct bioleaching of pyrite with O2,” appears in Earth and Planetary Science Letters.
