By directing pulses of laser light at atoms, researchers can study how radioactive elements decay in a matter of seconds. The method is described in a new thesis from the University of Gothenburg, which shows that the atomic nuclei of the elements neptunium and fermium are shaped like rugby balls. [...]

Monumental ship burials in Scandinavia may have started around a century earlier than previously thought, according to a paper published in the journal Antiquity. It reports the discovery of the remains of a 1,300-year-old ship buried on the Norwegian island of Leka, predating the Vikings. [...]

Also known as magnetoelectronics, spintronics rely on electron spin rather than electron charge, as found in traditional electronics. Although spintronics is still an emerging field, spintronic technologies are already found in hard disk drives and giant magnetoresistance sensors used in industrial and automotive applications. Once the right foundational materials are discovered and verified, including economical materials for altermagnets, spintronics could advance technologies from wireless communication to quantum computing. [...]

A study conducted at the Institute of Science and Technology of São Paulo State University (ICT-UNESP) in São José dos Campos, Brazil, shows that Moringa oleifera, also known as moringa or white acacia, has the potential to remove microplastics from water. The study, titled "Removal of Microplastics from Drinking Water by Moringa oleifera Seed: Comparative Performance with Alum in Direct and in-Line Filtration Systems," is published in the journal ACS Omega. [...]

The underground laboratory in Nevada where the U.S. conducts nuclear subcritical experiments is riddled with faults. Researchers have not confirmed whether any of these faults are active and could rupture during an earthquake, according to a presentation by members of the Defense Nuclear Facilities Safety Board delivered at the 2026 SSA Annual Meeting. [...]

Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do more than simply provide protection—they also influence the behavior of the protein receptors embedded in them. [...]

Researchers at University of Tsukuba have developed a method to differentiate the topography of medieval mountain castles from that of natural ridges using airborne light detection and ranging (LiDAR) data. This method is expected to be useful for detecting historically modified terrain, such as archaeological sites in mountainous regions, as well as for assessing the extent of topographic modifications and estimating the potential risk of landslides on modified slopes. [...]

Fish living downstream of wastewater treatment plants are accumulating antidepressants, opioids and other drugs of abuse in their bodies, according to a new study. Using a new analytical method they developed, a team of researchers from the University of Waterloo discovered that several substances that affect the central nervous system, including fentanyl, methadone and venlafaxine, were detected in small fish living in rivers that receive urban wastewater. [...]

The recovery of the ozone layer in Earth's stratosphere could be delayed by several years, according to an international study led by Swiss research institution Empa which included contributions from University of Bristol researchers. The cause is persistent emissions of so-called feedstock chemicals, which are still permitted as raw materials in industry. These ozone-depleting substances have so far been excluded from international agreements because, according to the current study, their emissions and use have been significantly underestimated. [...]

Thin films might not come up in conversation every day, but they are all around us. Take the metallic plastic films of chip bags, for example, or the anti-reflective coatings on eyeglasses. Even the coatings on pills that make them easier to swallow are thin films. Depositing extremely thin layers of materials in a consistent and uniform way is also crucial to the production of semiconductors, which are the foundation of modern electronics. [...]

The south coast of South Africa's Western Cape province is a rich source of fossil tracks and traces—clues suggesting what this environment may have been like many thousands of years ago. [...]

Where once there was ice, only rock remains. One of the glaciers in a chain of snow-capped mountains in the Colombian Andes has vanished due to high temperatures driven by climate change. [...]

Baby Neanderthals may have been much larger and grown much more quickly than their modern Homo sapiens counterparts, according to a new study of the most intact Neanderthal infant skeleton. Neanderthals (Homo neanderthalensis) are our closest extinct relatives, an ancient group of humans that lived in Eurasia from several hundred thousand years ago until they disappeared around 40,000 years ago. [...]

Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock solidified. The magnetization of these grains acts as a miniature compass needle, pointing toward ancient magnetic poles. This same principle applies to extraterrestrial samples, such as meteorites and lunar rocks, which preserve evidence of the early solar nebula's evolution. [...]

Massive blooms of Sargassum seaweed that have inundated coastlines across the Atlantic since 2011 likely originate off the coast of West Africa—forming years before they are visible and overturning long-standing assumptions about where these events begin. [...]
