Bioinspired strategy creates complex 3D curved structures via programmed shrinkage

The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces with specific functional advantages, such as facilitating t

Discrepancies in AI lunar crater catalogs discovered

A new Southwest Research Institute-led study compared eight AI-generated lunar crater catalogs, discovering that many of their published performance metrics drop sharply when the databases are evaluated using the same scientific standards humans are held to. Crater catalogs provi

'Outed' by the algorithm—how social media is revealing queer identity ahead of self-disclo

Social media algorithms are increasingly revealing users' sexual orientation or gender identity before they have consciously come out to themselves or others, according to new research. The new study published in Gender, Place & Culture coins the term "algorithmic outing"—when di

Researchers break a fundamental rule to create a new concept: Heat that can be directed an

Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, limits the ability to independently control heat absorptio

Massive calving episode in Greenland may foreshadow more rapid ice sheet loss

In November 2025, a study led by Adrien Wehrlé, a researcher in the Department of Geography at the University of Zürich, Switzerland, looked at the massive calving response of one of West Greenland's active glaciers, Sermeq Kujalleq in the Kangia icefjord (SKK), to the drainage o

Measuring iron in motion at Earth-core conditions

It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from Earth's surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several universities used the National Ignition Facility (NIF) t

Block-by-block AI maps uncover real urban air temperatures across 380 U.S. cities

Cities are often described as "heat islands," with media reports warning that some neighborhoods can be 20° F (7° C) hotter than others. But those temperatures are often based on satellite data rather than the conditions people actually experience, due to the dearth of near-surfa

Hidden deep-sea turbulence could alter climate and fisheries within one lifetime

Tiny, invisible swirls and twirls—not much bigger than a coin—deep below the ocean's surface are silently shaping some of the biggest forces shaping our climate: sea level rise, fisheries collapse, extreme flooding and how much carbon dioxide the ocean absorbs.

Falling water levels trigger a surge in methane emissions from Mediterranean reservoirs

Continental aquatic ecosystems, such as lakes and reservoirs, occupy a small proportion of Earth's surface but play a significant role in the global carbon cycle. It is estimated that more than 40% of global methane emissions originate from these ecosystems. However, the true sca

Self-propelled microparticles scrub stubborn biofilms, improving wound care and instrument

Newly developed microparticles can infiltrate stubborn bacterial matrices and release tiny oxygen bubbles to clean surfaces and wounds more efficiently than hydrogen peroxide or other cleaning agents alone, researchers at the University of Illinois Urbana-Champaign report. In two
