A study highlights a new approach in addressing conductive hearing loss. A team of scientists has designed a new type of hearing aid that not only improves hearing but also offers a safe, non-invasive alternative to implantable devices and corrective surgeries.

Scientists improved battery durability and energy density with a nano-spring coating.

Industrial waste gases, long seen as a major contributor to climate change, could soon be captured and repurposed into everyday household products such as shampoo, detergent, and even fuel.

A modulator has now broken the terahertz mark. The ultrafast component efficiently transmits large volumes of data into the fiber-optic network in a short space of time.

With today's data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic states can be read out by short current pulses, whereby recently discovered spintronic effects in purpose-built material systems could remove previous speed restrictions. Researchers are now providing proof of the feasibility of such ultrafast data sources. Instead of electrical pulses, they use ultrashort terahertz light pulses, thereby enabling the read-out of magnetic structures within picoseconds.

Researchers have discovered a handful of new CRISPR-Cas systems that could add to the capabilities of the already transformational gene editing and DNA manipulation toolbox. Of the new recruits, one system from bacteria commonly found in dairy cows shows particular promise for human health.

Up to 90% of abdominal surgeries result in adhesions -- abnormal scarring that ties together organs and tissues. A gel has now been shown to prevented adhesions in mice and pigs.

Researchers elucidate the complex physical mechanisms and fluid dynamics involved in a handclap, with potential applications in bioacoustics and personal identification, whereby a handclap could be used to identify someone.

Researchers have published a new study that dives deep into nickel-based cathodes, one of the two electrodes that facilitate energy storage in batteries.

Scientists have developed an approach that combines rehabilitation robotics with spinal cord stimulation to restore movement in people with spinal cord injuries. The technology enhances rehabilitation and enables activities like cycling and walking outdoors.

Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar structure in a few picoseconds. By combining ultrafast electronic and vibrational spectroscopies, the team captured these fleeting structural changes at the molecular level and showed that aromaticity appears before -- and then drives -- the structural planarization. Their findings lay the groundwork for designing more efficient photoactive materials, such as sensors and light-driven molecular switches, by leveraging the power of aromaticity in excited states.

Scientists have developed an innovative solar-powered method to transform sewage sludge -- a by-product of wastewater treatment -- into green hydrogen for clean energy and single-cell protein for animal feed.

When water freezes into ice or boils into vapor, its properties change dramatically at specific temperatures. These so-called phase transitions are fundamental to understanding materials. But how do such transitions behave in nanomaterials? A team of scientists now presents new insights into the complex nature of phase transitions in magnetic nanomaterials. Their findings reveal the coupling between magnetic and mechanical properties, paving the way for ultra-sensitive sensors.

Physicists have created a new computer code that could speed up the design of the complicated magnets that shape the plasma in stellarators, making the systems simpler and more affordable to build.

Researchers gathered emissions data from hundreds of US cities that either conducted a greenhouse gas emissions inventory, or reported they employed sustainability staff. The cities that conducted an inventory showed a statistically significant reduction in emissions between 2010 and 2015, while those with sustainability staff did not. Little research had previously been done to gauge effects of such measures and show that addressing emissions is meaningful, researchers argue.

Researchers have studied a new method to deliver antibiotics, specifically gentamicin, directly into the bladder tissue to better treat UTIs. They did this by creating nanogels combined with a special peptide (a small protein) that helps the drug get inside the cells where the bacteria are hiding. The results demonstrate that this approach proved highly effective when tested in animal models with UTIs, eliminating over 90% of the bacteria from the bladder.

Tracking targeted drug delivery is often a challenge due to limitations in the current imaging techniques. A recent study reports a breakthrough imaging technique that allows direct and highly sensitive tracking of gold nanoparticles (AuNPs) inside the body. This novel technique, which uses neutron activation of gold, could revolutionize cancer drug delivery by enabling real-time visualization of the gold nanoparticles without external tracers.

Researchers have demonstrated that phosphorene nanoribbons (PNRs) exhibit both magnetic and semiconducting properties at room temperature. The research establishes PNRs as a unique class of low-dimensional materials that challenges conventional views on magnetic semiconductors, and could provide a stepping stone to unlocking new quantum technologies.

Researchers created 'growth printing,' which mimics tree trunks' outward expansion to print polymer parts quickly and efficiently without the molds and expensive equipment typically associated with 3D printing.

Microplastics have been found almost everywhere that scientists have looked for them. Now these bits of plastic -- from 1 to 62 micrometers long -- have been found in the filtered solutions used for medical intravenous (IV) infusions. The researchers estimate that thousands of plastic particles could be delivered directly to a person's bloodstream from a single 8.4-ounce (250-milliliter) bag of infusion fluid.
