Why do some students become ever better at mathematics, while others plateau? Many people may think that mathematics is primarily about cognitive skills. A new study from the Norwegian University of Science and Technology (NTNU) provides a more nuanced view. The paper is published in the journal Contemporary Educational Psychology.
To sense their environment and respond accordingly, cells enlist membrane proteins as communication hubs, receiving molecular messages from outside and triggering responses inside. One of these proteins is Toll-like receptor 4 (TLR4), an immune receptor that plays an essential role in protecting against infections. But overactivity of TLR4 has been linked to inflammatory disorders like sepsis, arthritis and inflammatory bowel disease, making it an attractive target for therapies. Despite its appeal, TLR4 is difficult to manipulate precisely, and no FDA-approved drugs specifically block it.
In her dissertation, Hanna Entsalo examines how public policies, such as policy strategies and legislation, influence transitions toward the circular economy and sustainability. Entsalo works as a researcher in the Circular Economy Solutions Unit at the Finnish Environment Institute. Her work focuses on circular economy policy instruments, sustainability transitions and innovation policy, particularly at the national and EU levels.
Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central stellar bulge. Their paper, published in Monthly Notices of the Royal Astronomical Society, suggests that galaxies without a central bulge grow black holes just as effectively as galaxies that have one—a surprising sign that black holes don't need galaxy mergers to grow normally.
Aerosols are small particles suspended in our atmosphere. They come in many flavors: Wildfire smoke, pollen, desert dust, sea salt lofted by powerful storms, volcanic sulfates and emissions from engines and industrial processes are all examples.
When we speak with Luyao Huang, her Ph.D. project at Leiden University is in full swing. Two papers—a systematic literature review and a case study on an interdisciplinary course—are already behind her. Next year, she will carry out a study in which teachers react to various scenarios. Today, Huang tells us about her most recent study: a deep dive into student collaboration.
In the movie, a giant iceberg from Greenland floats into the sea, imperiling millions—but is that even possible?
The circular photogalvanic effect (CPGE), a phenomenon that generates helicity-dependent photocurrents in noncentrosymmetric materials, can originate purely from a crystal's internal structure without a contribution from the surface, a study from Science Tokyo reveals.
John Daigle, professor of forest recreation management at the University of Maine, co-authored the first paper in a series designed to help communities nationwide prepare for future natural disasters and other extreme weather events.
Once called a "pipe dream," quantum computers are now approaching practical use. Companies and research institutes around the world are in fierce competition to develop this technology, which has the potential to rapidly perform some calculations that are extremely difficult even for conventional supercomputers.
Spatial transcriptomics can reveal where thousands of genes are active across a tissue, creating molecular maps at single-cell resolution. But comparing two such maps is difficult: thin slices of tissue may be rotated, stretched or otherwise distorted, so equivalent regions do not automatically line up.
So far this year has been ridiculously hot. If it stays that way, 2026 could set a sobering new record
