A substance-use prevention program delivered to students and their families in the sixth and seventh grades led to wide-ranging benefits well into adulthood and—for those who became parents—even positively affected their children, according to a new study by researchers in the
Gravitational waves are tiny ripples in the fabric of spacetime that are produced when massive objects in the cosmos accelerate or collide. By detecting these waves, astrophysicists can study various cosmic events, including black hole mergers, neutron star collisions and the

Laser dicing, a technique that uses focused laser pulses to separate individual chips from a semiconductor wafer, is increasingly favored over mechanical blade cutting because it can process delicate, low-strength materials with minimal physical stress. However, achieving
An international study led by the Universities of Córdoba and Pisa used isotopic analysis to reconstruct the dietary traces left in human remains found in an Italian necropolis, revealing what daily life was like in that community 2,700 years ago. Despite the passage of time,
Doctors can often detect diseases in humans using minimally invasive methods, like blood or urine tests, before symptoms become severe. Now, researchers at the Woods Hole Oceanographic Institution (WHOI) are applying a similar concept to coral reefs, showing that the water
Complex simulations—the most intricate of their kind to date—carried out by an international research team led by scientists at Heidelberg University's Institute for Physical Chemistry, have revealed how water governs the way protons move through it. Using their modeling,
Archaeological excavations generate a vast quantity of documents of various types and formats, which constitute a scientific heritage of great value. However, the way this data is organized, documented and preserved remains highly varied. This is the main conclusion of the

An SKKU research team led by Professor Travers B. Child of the SKK Graduate School of Business (SKK GSB) has become the first in the world to use micro-level data to demonstrate that aid fragmentation—the phenomenon in which numerous international aid agencies operate
A new study suggests that simple molecules on early Earth may have worked together to create more stable, cell-like structures, offering fresh clues about one of science's biggest questions: how life began. Led by Dr. Moran Frenkel-Pinter of Hebrew University and her
With global warming and extreme weather intensifying, can animals raise their thermal tolerance to cope with a continuously warming environment? A joint research project by the Division of Science at Lingnan University and an international research team conducted experiments on
A research group led by Tetsuhiro Hatakeyama from the Earth-Life Science Institute (ELSI) at the Institute of Science Tokyo has revealed how a seemingly self-destructive survival strategy could persist in yeast for hundreds of millions of years. By combining population dynamics
Wild seabirds that face high energy demands during the breeding season go on to migrate farther and raise more chicks the next year, but at a cost to their own survival. An international team led by researchers from Nagoya University raised the energy cost of flight for some
More than 120 fish species have migrated from the Red Sea to the Mediterranean since the Suez Canal opened more than 150 years ago. Now, researchers at Tel Aviv University have developed a statistical model that can predict which species are likely to make the journey next.
School cellphone bans might seem like a good way to improve learning for elementary school children, but new research published in Behavioral Sciences shows that simply owning a cellphone correlates with worse reading comprehension. Whether a child brings the phone to school
Strengthening the bond between people and nature—that is the aim of a German–Dutch EU project involving Oldenburg. The reasoning behind this is that people who feel they are part of the environment are more likely to campaign for its preservation.
Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have uncovered the molecular mechanism by which amino acid signals activate this
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal scaffolding and, in the process, release their
Physicists from Heinrich Heine University Düsseldorf (HHU), the Technical University of Darmstadt, Sapienza University in Rome and the University of Camerino (both in Italy) have calculated the fundamental laws of thermodynamics for a gas composed of spinning particles. In the
We've been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it's gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should do—in this case, look at and characterize potentially
By analyzing 100,000 California Department of Forestry and Fire Protection inspection records from 2013 to 2024, researchers at the University of California, Irvine have identified the key environmental and human factors responsible for the most destructive wildfires, and they
What happens inside a citrus tree long before leaves turn yellow, roots decline, and fruit quality suffers? Researchers from the University of Florida Citrus Research and Education Center—Diann S. Achor, Camila Ribeiro, Jinyun Li and Nian Wang—have created a detailed
Many of today's electronic devices—from the semiconductors in your cell phone to the photovoltaic cells in your solar panels—are built on thin-film substrates. The thin film is an electrically conductive material, while the substrate is an inert material. Or is it?

Every ancient language that has ever been deciphered needed an anchor. Usually that's a bilingual text, like the Rosetta Stone, or a known relative to compare it to. Linear A, the writing system of the Bronze Age Minoan civilization on the Greek island of Crete, has neither.
Most of the carbon released during Canada's record-breaking 2023 wildfire season came from burning soil and peat, rather than trees, according to new research from McMaster University.
