- Between 2006 and 2017, North Korea conducted six underground nuclear tests at its vast testing site at Mount Mantap in North Hamgyong province. Typically, underground explosions trigger an intense burst of minor earthquakes that die down once testing stops. But geologists have detected far more seismic activity after the final detonation, and it has persisted for years.
- Ancient Chinese authorities used many creative ways to punish people, often with methods designed to mark them for life. One brutal example mentioned repeatedly in historical texts is cutting off a person's nose. However, archaeologists in China have never found skeletal evidence to prove that it occurred. But that may have changed following the discovery of a skeleton of a woman who lived in China about 700 years ago.
- Douglas Seiler painstakingly sourced papyrus and reed pens from Egypt and traditional lampblack ink from Japan, then paid some high school students to inscribe the papyrus with lines from Star Wars and the Bible and a quote from the '60s sci-fi TV show The Outer Limits.
- Seeing a bachelor's thesis published in a scientific journal is relatively uncommon. For three theses linked to the same research group to result in scientific publications within just three months is downright rare. Yet that is exactly what has happened in Elsebeth Schröder's research group at the Division of Quantum Device Physics.
- Physicists at UC Santa Barbara have extended the search for evidence of microscopic black holes produced at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). The formation of these tiny, fleeting objects at the LHC represents one way theorists have sought to resolve anomalies in our understanding of the basic structure of spacetime, while the method used to look for them demonstrates a new way of searching for new particles.
- Researchers have engineered a new material that is an extreme thermal insulator, is exceptionally stiff and can be printed as a thin film at large scales. The material has one of the lowest thermal conductivity profiles of any dense, or nonporous, material—approaching the theoretical limit of how good a material can be as a thermal insulator.
- Magnetic reconnection is a process that occurs when the magnetic fields of a conductive plasma quickly rearrange and release massive amounts of stored magnetic energy. It is widely thought to be the underlying mechanism behind cosmic events such as solar flares and substorms in Earth's magnetosphere.
- Each summer, researchers from Hokkaido University returned to the Qaanaaq Ice Cap in northwestern Greenland to measure changes in the ice surface using aluminum poles drilled into the ice. Their 13-year record shows how the ice cap changed from 2012 to 2025.
- CRISPR may be a powerful technology for gene editing, but the system existed in bacteria long before scientists began using it. For billions of years, CRISPR has acted as a natural immune system in bacteria and other microbes, helping defend them against invading viruses. But now, two new studies, published in Science, describe a similar RNA-guided system that originated in the viruses themselves and appears to be a precursor to CRISPR.
- Korean researchers have developed a method to strengthen biodegradable plastics using hemp hurd, an agricultural byproduct. The approach is expected to be applicable to other large-volume agricultural residues, including soybean stalks and rice straw.
- The humble coffee filter has the relatively simple job of letting the coffee through and leaving the grounds behind. But researchers from the ARC Center of Excellence for Carbon Science and Innovation (COE-CSI) are exploring whether a filter operating on the molecular scale can do something much more difficult: separate the caffeine from the coffee itself.
- Molecular gases are a new form of artificial quantum matter. However, when these molecules collide, they are often lost extremely rapidly. Researchers from Radboud University and Columbia University have been able to suppress this collisional loss, paving the way for strongly interacting quantum matter. This new artificial quantum matter allows researchers to study quantum behavior relevant to electrons in real materials. Their results are published in Science.
- During routine beach litter surveys on the subtropical island of Okinawa, Japan, researchers came across small, brightly colored specks in the pale coral rubble. Back at the lab, spectroscopic and microscopic analyses revealed that these specks are, in fact, melted polymers from common household plastics that have seeped inseparably into the skeletal pores of the dead coral pieces.
- When the solar system first took up the task of building solid bodies—such as planets, moons and protoplanets—it basically had a choice between two ingredients: heat-forged chondrules, which were millimeter-sized bits of rock, and matrix, a fine-grained, cold dust loaded with water ice and organic molecules. And from the get-go, the solar system chose fire.
- A team of researchers, including those from the University of Tokyo, spotted a rare kind of planet that's unusually hot and eccentric. TOI-1355 b orbits its star, TOI-1355, which is also much hotter than our sun, in a strange way and incredibly quickly, completing an orbit in about two Earth days. The work is published in the journal Publications of the Astronomical Society of Japan.
- One of Dublin's "lost" medieval castles has been found hiding in plain sight inside University College Dublin's Roebuck Castle. New research reveals that substantial remains of the Norman castle of Roebuck, an important fortress on one of the approach roads into the medieval city of Dublin, are preserved within the modern-day building.
- A new study sheds light on how Syrian archaeologists risked their lives to rescue approximately 30,000 priceless artifacts from the Deir ez-Zor Museum during the summers of 2014 and 2015 as the city faced the imminent threat of capture by the Islamic State of Iraq and Syria (ISIS), also known as Daesh.
- Cysteine is one of the main building blocks that cells use to make proteins. But this amino acid is a double-edged sword—too much cysteine is toxic to the cell. Cells therefore keep free cysteine levels to a minimum, converting most of the amino acid into the antioxidant glutathione.
- A new way to accurately measure the distance between quasar pairs—the blazing, black-hole-powered centers of distant galaxies that appear side by side in space—is showing promise through University of Alberta research.
- A new approach that changes just one atom in plastic-degrading enzymes could help make them more efficient while maintaining their stability, according to new research from The Australian National University published in Angewandte Chemie International Edition.
