Scientists observe how blobs form crystals and discover a new crystal type

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:16pm
Crystals -- from sugar and table salt to snowflakes and diamonds -- don't always grow in a straightforward way. Researchers have now captured this journey from amorphous blob to orderly structures. In exploring how crystals form, the researchers also came across an unusual, rod-shaped crystal that hadn't been identified before, naming it 'Zangenite' for the graduate student who discovered it.

Advancing AI for diverse applications in manufacturing, business and education

Computers and Math from Science Daily Feed - Mon, 04/28/2025 - 7:12pm
Large language models (LLMs) are at the forefront of artificial intelligence (AI) and have been widely used for conversational interactions. However, assessing the personality of a given LLM remains a significant challenge. A research team has now developed an AI-driven assessment system, the Language Model Linguistic Personality Assessment (LMLPA), with capabilities to quantitatively measure the personality traits of LLMs through linguistic analysis.

Breakthrough extends fuel cell lifespan beyond 200,000 hours, paving the way for clean long-haul trucking

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:09pm
Researchers have developed a new catalyst design capable of pushing the projected fuel cell catalyst lifespans to 200,000 hours. The research marks a significant step toward the widespread adoption of fuel cell technology in heavy-duty vehicles, such as long-haul tractor trailers. While platinum-alloy catalysts have historically delivered superior chemical reactions, the alloying elements leach out over time, diminishing catalytic performance. The degradation is further accelerated by the demanding voltage cycles required to power heavy-duty vehicles. To address this challenge, the team has engineered a durable catalyst architecture with a novel design that shields platinum from the degradation typically observed in alloy systems.

Study using simulations highlights power of pooled data in environmental health research

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:09pm
Conflicting findings in environmental epidemiology have long stalled consensus on the health effects of toxic chemicals. A new study suggests that one major reason for these inconsistencies may be the limited exposure ranges in individual studies -- leading to underpowered results and unclear conclusions.

New research shatters long-held beliefs about asteroid Vesta

Space and time from Science Daily Feed - Mon, 04/28/2025 - 7:06pm
For decades, scientists believed Vesta, one of the largest objects in our solar system's asteroid belt, wasn't just an asteroid and eventually concluded it was more like a planet with a crust, mantle and core. Now, new research flips this notion on its head. Astronomers reveals Vesta doesn't have a core. These findings startled researchers who, until that point, assumed Vesta was a protoplanet that never grew to a full planet.

Walking Moon Robots Possibly More Reliable than Lunar Rovers

Universe Today Feed - Mon, 04/28/2025 - 6:38pm

How can walking robots deliver more efficient in-situ robotic exploration on the Moon compared to other types of robots? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from the University of Southern California (USC) discussed the benefits of using legged robots for lunar exploration regarding gait speed (walking speed). This study has the potential to help engineers, scientists, mission planners, and astronauts develop novel robotic designs to conduct more efficient science and mission objectives on future Moon surface missions.

The Moon is a Constant Source of Minimoons

Universe Today Feed - Mon, 04/28/2025 - 3:59pm

Earth has a number of companions in space; of course the Moon is the most well known but there are a host of smaller objects that visit us, complete a few orbits then head off again. A team of astronomers have detected four objects like this and have performed spectroscopic analyses on them. They found that their surface composition is similar to eh Moon suggesting that it’s a major source of these temporary satellites instead of the asteroid belt.

A Huge Molecular Cloud Found Close to the Solar System

Universe Today Feed - Mon, 04/28/2025 - 3:10pm

The Orion Nebula is a fabulous example of a vast cloud of electrically charged gas which is emitting bright radiation. If the atoms in the gas are cool enough though, they can form giant molecular clouds that obscure light, these are known as dark nebula. A team of astronomers have now found an enormous cloud of molecular hydrogen in our own cosmic backyard just 300 light years away. The cloud contains 3,400 times the mass of the Sun and if we could see it, it would stretch nearly 40 times the width of the Moon across the sky.
