Study of velvet worm slime could revolutionize sustainable material design

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

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

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

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

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

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.

Accelerating drug discovery with a single carbon atom

A research team has pioneered a groundbreaking method that could accelerate drug discovery and reduce pharmaceutical development costs. Their work introduces a safe, sustainable way to insert a single carbon atom into drug molecules at room temperature.

Breakthrough in fuel cell recycling turns 'forever chemicals' into renewable resources

A new technique that uses soundwaves to separate materials for recycling could help prevent potentially harmful chemicals leaching into the environment.

Experimental quantum communications network

Researchers recently connected their campuses with an experimental quantum communications network using two optical fibers.

How AI tools can improve manufacturing worker safety, product quality

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?

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?

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.

Bridging Worlds: Physicists develop novel test of the Holographic Principle

In the quest toward finding the correct theory of quantum gravity, physicists have been testing the holographic principle which, they say, is a key property of any valid theory of quantum gravity.

Scientists discover a new way to convert corn waste into low-cost sugar for biofuel

Scientists have found a new way to produce sugar from corn stalks and other crop waste, potentially opening a new pathway to sustainable biofuels.

New silver mass brings us a step closer in our understanding of the antineutrino mass

Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements have revealed that beta decay of the silver-110 isomer has a strong potential to be used for the determination of electron antineutrino mass. The result is an important step paving the way for future antineutrino experiments.

Accordion effect makes graphene stretchable

Graphene is a 'miracle material': mechanically extremely strong and electrically highly conductive, ideal for related applications. Using a unique method physicists have now made graphene drastically more stretchable by rippling it like an accordion. This paves the way for new applications in which certain stretchability is required (e.g. wearable electronics).

Fruit and microbes boost biogas production and fermentation

A new study shows that adding fruit and microbes to alfalfa, a protein-rich feed for livestock, improves fermentation and biogas production.

Robotic touch sensors are not just skin deep

Researchers argue that the problem that has been lurking in the margins of many papers about touch sensors lies in the robotic skin itself.

Topical gel relieved ear infections in animals after just one dose

Ear infections are a common and painful occurrence in infants and toddlers. Oral antibiotics are often prescribed for a week to treat the condition, but these drugs can trigger side effects that disrupt treatment, which can lead to infection recurrence and antibiotic resistance. Now, researchers report a topical antibiotic gel that, applied once, cured middle ear infection within 24 hours in chinchillas.

Big problem for fusion energy solved

A new shortcut can help engineers design leak-proof magnetic confinement systems for fusion reactors 10 times as fast as the gold standard method, without sacrificing accuracy. While several other big challenges remain for all magnetic fusion designs, this advance addresses the biggest challenge that's specific to a type of fusion reactor first proposed in the 1950s, called a stellarator.
