Putting sound waves to work to create safer public spaces      (via sciencedaily.com)     Original source 

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors built a system of piezoelectric sensors that can be installed in walls, floors, and ceilings to absorb sound waves and collect their energy. They used computer simulations to fine-tune variables including the voltage needed to power the main device component, the frequency and intensity of the input sound, and piezoelectric sensors tested in parallel and serial configurations.

How tiny hinges bend the infection-spreading spikes of a coronavirus      (via sciencedaily.com)     Original source 

Far from being stiff and pointy, a coronavirus's infectious spikes are shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. A new study suggests that disabling those hinges could block infection.

This wireless, handheld, non-invasive device detects Alzheimer's and Parkinson's biomarkers      (via sciencedaily.com)     Original source 

An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer's and Parkinson's Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone. The team tested the device on in vitro samples from patients and showed that it is as accurate as the state of the art method. Ultimately, researchers plan to test saliva and urine samples with the biosensor. The device could be modified to detect biomarkers for other conditions as well. The device relies on electrical rather than chemical detection, which researchers say is easier to implement and more accurate.

AI programs spat out known data and hardly learned specific chemical interactions when predicting drug potency      (via sciencedaily.com)     Original source 

Artificial intelligence (AI) is on the rise. Until now, AI applications generally have 'black box' character: How AI arrives at its results remains hidden. A cheminformatics scientist has now developed a method that reveals how certain AI applications work in pharmaceutical research. The results are unexpected: the AI programs largely remembered known data and hardly learned specific chemical interactions when predicting drug potency.

Recycling of water-based adhesive achieved by changing pH      (via sciencedaily.com)     Original source 

A research team has developed a reversible, water-based glue that has good adhesion in the neutral pH range, but can be detached again in strongly acidic or alkaline environments. The novel adhesive system, which is based on electrostatic interactions, has bond strengths somewhere between those of structural adhesives and pressure-sensitive adhesives. The new adhesive also bonds 'difficult' surfaces such as water-repellent polypropylene.

quantum mechanics: Unlocking the secrets of spin with high-harmonic probes      (via sciencedaily.com)     Original source 

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of researchers has learned to control with remarkable precision, potentially redefining the future of electronics and data storage.

New way to count microbes speeds research, cuts waste, could lead to new antibiotics      (via sciencedaily.com)     Original source 

Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The technique could revolutionize the way microbiology experiments are conducted, allowing researchers to test potential new antibiotics in a fraction of the time.

A breath of fresh air keeps drug-producing cells alive longer      (via sciencedaily.com)     Original source 

Researchers have developed a novel device that produces oxygen inside of a 'living pharmacy' implant in order to keep cells alive inside the self-contained device. The device produses oxygen through a smart, energy-efficient version of water splitting. In new experiments, the novel device kept cells (70-80%) alive for close to a month in low oxygen conditions in vitro, or weeks in vivo.

Understanding the dynamic behavior of rubber materials      (via sciencedaily.com)     Original source 

Rubber-like materials can exhibit both spring-like and flow-like behaviors simultaneously, which contributes to their exceptional damping abilities. To understand the dynamic viscoelasticity of these materials, researchers have recently developed a novel system that can conduct dynamic mechanical analysis and dynamic micro X-ray computed tomography simultaneously. This technology can enhance our understanding of the microstructure of viscoelastic materials and pave the way for the development of better materials.

Device 'smells' seawater to discover, detect novel molecules      (via sciencedaily.com)     Original source 

Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.

Experiment shows biological interactions of microplastics in watery environment      (via sciencedaily.com)     Original source 

Scientists have learned over the years that when aquatic organisms such as zooplankton become exposed to microplastics, they eat poorly. Research now shows that their plastic-induced eating difficulties also limit the ability of zooplankton to control algal proliferation. When algae bloom out of control, this presents a problem because some species produce toxins. Also, algal blooms can be associated with pea-soupy, unattractive bodies of water and contribute to hypoxia, a low-oxygen condition that may lead to fish kills.

Video technology could transform how scientists monitor changes in species evolution and development      (via sciencedaily.com)     Original source 

New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.
