Scientists have found a way to make perovskite solar cells not only highly efficient but also remarkably stable, addressing one of the main challenges holding the technology back from widespread use. 

Perovskite has long been hailed as a game-changer for the next generation of solar power. However, advances in material design are still needed to boost the efficiency and durability of solar panels that convert sunlight into electricity. 

Led by Professor Thomas Anthopoulos from The University of Manchester, the research team achieved this by fine-tuning the molecules that coat the perovskite surfaces. They utilized specially designed small molecules, known as amidinium ligands, which act like a molecular “glue” to hold the perovskite structure together. 

This exotic form of ice just got weirder

Researchers hoped to clarify the boundaries between different types of superionic water – the hot, black ice believed to exist at the core of giant ice planets. Instead, they found multiple atomic stacking patterns coexisting in overlapping configurations never seen before in this phase of water. 

Superionic water – the hot, black and strangely conductive form of ice that exists in the center of distant planets – was predicted in the 1980s and first recreated in a laboratory in 2018. With each closer look, it continues to surprise researchers.

In a recent study published in Nature Communications, a team including researchers at the Department of Energy’s SLAC National Accelerator Laboratory made a surprising discovery: Multiple atomic packing structures can coexist under identical conditions in superionic water.

Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries – the next generation of batteries that can store more energy, are safer to operate, and charge faster than conventional lithium-ion batteries. 

All-solid-state batteries are considered a promising solution for electromobility, mobile electronics, and stationary energy storage – in part because they do not require flammable liquid electrolytes and therefore are inherently safer than conventional lithium-ion batteries. 

Two key problems, however, stand in the way of market readiness: On the one hand, the formation of lithium dendrites at the anode remains a critical point. These are tiny, needle-like metal structures that can penetrate the solid electrolyte conducting lithium ions between the electrodes, propagate toward the cathode, and ultimately cause internal short circuits. On the other hand, an electrochemical instability – at the interface between the lithium metal anode and the solid electrolyte – can impair the battery’s long-term performance and reliability. 

Stem cell engineering breakthrough paves way for next-generation living drugs

For the first time, researchers at the University of British Columbia have demonstrated how to reliably produce an important type of human immune cell—known as helper T cells—from stem cells in a controlled laboratory setting.  

The findings, published today in Cell Stem Cell, overcome a major hurdle that has limited the development, affordability and large-scale manufacturing of cell therapies. The discovery could pave the way for more accessible and effective off-the-shelf treatments for a wide range of conditions like cancer, infectious diseases, autoimmune disorders and more.   

“Engineered cell therapies are transforming modern medicine,” said co-senior author Dr. Peter Zandstra, professor and director of the UBC School of Biomedical Engineering. “This study addresses one of the biggest challenges in making these lifesaving treatments accessible to more people, showing for the first time a reliable and scalable way to grow multiple immune cell types.”

The study outlines a new scenario for understanding how genome regulation and chromatin organization influence the evolution of animal body plans. “Our study opens up new paths for understanding the biological and evolutionary significance of this extreme conservation, since for the first time we can compare these very ancient regulatory elements across different lineages, a scientific breakthrough that allows us to understand what properties they share,” says Ignacio Maeso, professor at the UB’s Department of Genetics, Microbiology and Statistics. 

How Many Ghost Particles All the Milky Way’s Stars Send Towards Earth

Every second, a trillion of the elusive ghost particles, the neutrinos, pass straight through your body. Now, astrophysicists from the University of Copenhagen have mapped how many ghost particles all the stars in the Milky Way send towards Earth, and where in the galaxy they originate. This new map could help us track down these mysterious particles and unlock knowledge about our Galaxy that has so far been out of reach. 

They’re called ghost particles for a reason. They’re everywhere – trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos – without us noticing. These so-called neutrinos are elementary particles that are invisible, incredibly light, and interact only rarely with other matter. The weakness of their interactions makes neutrinos extremely difficult to detect. But when scientists do manage to capture them, they can offer extraordinary insights into the universe. 

What Causes Some People’s Gut Microbes to Produce High Alcohol Levels?

A study of people with a rare condition known as auto-brewery syndrome has found a link between gut microbes and symptoms of intoxication, pointing to new treatment strategies.

Researchers at University of California San Diego, Mass General Brigham, and their colleagues have identified specific gut bacteria and metabolic pathways that drive alcohol production in patients with auto-brewery syndrome (ABS). The rare and often misunderstood condition causes people to experience intoxication without drinking alcohol. The study was published in Nature Microbiology on January 8, 2026.

ABS occurs when gut microbes break down carbohydrates and convert them to ethanol (the alcohol found in intoxicating beverages), which then enters the bloodstream. While the metabolism of carbohydrates can produce small amounts of alcohol in everyone, levels can be high enough to cause intoxication in people with ABS. The condition is extremely rare but likely underdiagnosed due to a lack of awareness, diagnostic challenges, and stigma.

How light reflects on leaves may help researchers identify dying forests

Early detection of declining forest health is critical for the timely intervention and treatment of droughted and diseased flora, especially in areas prone to wildfires. Obtaining a reliable measure of whole-ecosystem health before it is too late, however, is an ongoing challenge for forest ecologists.

Traditional sampling is too labor-intensive for whole-forest surveys, while modern genomics—though capable of pinpointing active genes—is still too expensive for large-scale application. Remote sensing offers a high-resolution solution from the skies, but currently limited paradigms for data analysis mean the images obtained do not say enough, early enough.

A new study from researchers at the University of Notre Dame, published in Nature: Communications Earth & Environment, uncovers a more comprehensive picture of forest health. Funded by NASA, the research shows that spectral reflectance—a measurement obtained from satellite images—corresponds with the expression of specific genes.

Reflectance is how much light reflects off of leaf material, and at which specific wavelengths, in the visible and near-infrared range. Calculated as the ratio of reflected light to incoming light and measured using special sensors, reflectance data reveals a unique signature specific to the leaf’s composition and condition.

Sponges are among earth’s most ancient animals, but exactly when they evolved have long puzzled scientists. Genetic information from living sponges, as well as chemical signals from ancient rocks, suggests that sponges evolved at least 650 million years ago. 

This evidence has proved highly controversial as it predates the fossil record of sponges by a minimum of 100 million years. Now an international team of scientists led by Dr M. Eleonora Rossi, from the University of Bristol’s School of Biological Sciences, has solved this conflict by examining the evolution of sponge skeletons.  The research was published in Science Advances. 

Living sponges have skeletons composed of millions of microscopic glass-like needles called spicules. These spicules also have an extremely good fossil record, dating back to around 543 million years ago in the late Ediacaran Period. Their absence from older rocks has led some scientists to question whether earlier estimates for the origin of sponges are accurate. 

A molecular switch that controls transitions between single-celled and multicellular forms

The marine yeast Hortaea werneckii switches between unicellular and multicellular forms depending on food availability. These microscope images show (left to right): individual cells dividing on their own, fully connected multicellular chains that develop directly from single cells, and multicellular forms transitioning back by producing unicellular offspring. This flexibility helps the yeast adapt to changing ocean conditions.

How did multicellular life evolve from single cells? Nagoya University researchers have identified genes in marine yeast that may help answer this fundamental question. 

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate between life forms provides new insights into how multicellular life may have evolved from single-celled ancestors and eventually led to complex organisms like animals and plants. 

Published in Nature, the study represents an exceptionally detailed molecular explanation of how clonal multicellularity, where all cells descend from a single ancestor, can be achieved and controlled at the genetic level.
