Smart spongy device captures water from thin air

Wed, 07/05/2025 - 17:59
Engineers have invented a sponge-like device that captures water from thin air and then releases it in a cup using the sun's energy, even in low humidity where other technologies such as fog harvesting and radiative cooling have struggled. The water-from-air device remained effective across a broad range of humidity levels (30 -- 90%) and temperatures (5 -- 55 degrees Celsius).

Smart lactation pads can monitor safety of breast milk in real time

Wed, 07/05/2025 - 17:58
Scientists have developed a lactation pad equipped with sensing technology that allows parents of newborns to monitor breast milk in real time. The device is capable of ensuring that breast milk contains safe levels of the painkiller acetaminophen, which is often prescribed after childbirth and can be transferred to breastfeeding infants.

Piecing together the brain puzzle

Wed, 07/05/2025 - 17:58
Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this complicated network requires a precise look into how these nerve cells are arranged and connected. A new method makes use of off-the-shelf light microscopes, hydrogel and deep learning.

New vacuum-assisted extrusion technique improves performance of polymer prints

Wed, 07/05/2025 - 17:56
Scientists have developed a vacuum-assisted extrusion method that reduces internal porosity -- by up to 75% -- in large-scale 3D-printed polymer parts. Large-scale additive manufacturing has been hindered by internal porosity that weaken printed components. Reducing porosity is key to improving overall performance. Researchers tackled this challenge with a novel approach: integrating a vacuum hopper during the extrusion process to remove trapped gases and minimize void formation in fiber-reinforced materials.

Cracking the code: Deciphering how concrete can heal itself

Wed, 07/05/2025 - 17:56
Lichen is an understated presence in our everyday world, often found clinging to trees and rocks. Its true beauty lies in its unique symbiotic system of fungi and algae, or cyanobacteria, that form a self-sustaining partnership, allowing it to thrive in even the harshest conditions. With that inspiration, researchers created a synthetic lichen system that collaborates like natural lichens. Their system uses cyanobacteria, which turns air and sunlight into food, and filamentous fungi, which produces minerals that seal the cracks. Working together, these microbes survive on nothing more than air, light and water. The autonomy of this system sets it apart from previous self-healing concrete endeavors.

Vapor-deposited perovskite semiconductors power next generation circuits

A research team has developed a groundbreaking technology poised to revolutionize next-generation displays and electronic devices.

Study of velvet worm slime could revolutionize sustainable material design

Tue, 06/05/2025 - 22:09
A new discovery about the slime ejected by velvet worms could revolutionize sustainable material design. The findings outline how a naturally occurring protein structure, conserved across species from Australia, Singapore and Barbados over nearly 400 million years of evolution, enables the slime's transformation from liquid to fiber and back again. It's a discovery that could inspire next-generation recyclable bioplastics.

Practical new tool created for detecting nanoplastics and microplastics in the environment

Tue, 06/05/2025 - 22:09
A team of researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment. These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult. The 3D-printed HoLDI-MS test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation. The researchers say it also will work for detection of waterborne plastic particles. HoLDI-MS stands for hollow-laser desorption/ionization mass spectrometry.

Ultra-thin bismuth holds unexpected promise for green electronics

Tue, 06/05/2025 - 22:09
Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery that challenges conventional wisdom in physics suggests that bismuth, a metal, could serve as the foundation for highly stable electronic components. The researchers observed a mysterious electrical effect in ultra-thin bismuth that remains unchanged across a wide temperature range, from near absolute zero (-273 C) to room temperature.

Okra, fenugreek extracts remove most microplastics from water

Tue, 06/05/2025 - 20:22
The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer. Previously, researchers proposed using these sticky natural polymers to clean up water. Now, they report that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics in ocean water, freshwater and groundwater.

Gender characteristics of service robots can influence customer decisions

Tue, 06/05/2025 - 20:22
While service robots with male characteristics can be more persuasive when interacting with some women who have a low sense of decision-making power, 'cute' design features -- such as big eyes and raised cheeks -- affect both men and women similarly, according to new research.

Development, agriculture present risks for drinking water quality

Tue, 06/05/2025 - 18:15
Converting forest land to urban development or agricultural use can present risks to water quality when done near streams or river sources. This study examined data from 15 water treatment plants in the Middle Chattahoochee watershed to model the impacts of four potential land use scenarios several decades into the future.

How AI tools can improve manufacturing worker safety, product quality

Tue, 06/05/2025 - 18:13
Recent artificial intelligence advances have largely focused on text, but AI increasingly shows promise in other contexts, including manufacturing and the service industry. In these sectors, targeted AI improvements can improve product quality and worker safety, according to a new study.

Would a musical triangle of any other shape sound as sweet?

Tue, 06/05/2025 - 18:13
Researchers captured sound fields around musical triangles. They wanted to understand the physical properties of the triangle instrument, test assumptions about the contribution of the triangle shape, and capture clear documentation through pictures of the sound waves around the triangle. Using acousto-optic imaging to study detailed characteristics of sound vibration pattern, the team found results that suggest resonance may occur in the triangle's semi-open space.

Do manta rays benefit from collective motion?

Tue, 06/05/2025 - 18:13
Researchers model the motions of groups of manta rays to study how group dynamics affect their propulsion, studying different formations of three manta rays: in tandem, in a triangular setup with one manta ray in front leading two behind, and in an inverse triangular configuration with one manta ray trailing the other two. They found the tandem formation only significantly increases propulsion for the middle manta ray, and the two triangular setups result in overall decreased efficiency compared to a single swimmer on its own. These findings can help optimize formations for underwater vehicle operations.
