Smart films help to make loudspeakers lighter and more energy-efficient      (via sciencedaily.com)     Original source 

Scientists are developing intelligent materials that are opening up new avenues in sound reproduction technology: lightweight loudspeakers that use far less energy than their conventional counterparts, novel shapes for sound and signal generators and applications involving noise cancelling textiles. The basis for these smart materials are ultrathin silicone films that can act as artificial muscles with their own built-in sensors.

English language pushes everyone -- even AI chatbots -- to improve by adding      (via sciencedaily.com)     Original source 

A linguistic bias in the English language that leads us to 'improve' things by adding to them, rather than taking away, is so common that it is even ingrained in AI chatbots, a new study reveals.

Wastewater more potent breeding ground for antibiotic resistance than previously known      (via sciencedaily.com) 

Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.

Hope for salamanders? Study recalibrates climate change effects      (via sciencedaily.com) 

For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.

Engineered E. coli delivers therapeutic nanobodies to the gut      (via sciencedaily.com)     Original source 

Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.

Path to net-zero carbon capture and storage may lead to ocean      (via sciencedaily.com) 

Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbonization through hybrid ion exchange material). The research has demonstrated a 300 percent increase in the amount of carbon captured compared with existing direct air capture methods.

Mathematical model provides bolt of understanding for lightning-produced X-rays      (via sciencedaily.com) 

In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons -- the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why lightning produced X-rays. Now, two decades later, a team has discovered a new physical mechanism explaining naturally occurring X-rays associated with lightning activity in the Earth's atmosphere.

Ants took over the world by following flowering plants out of prehistoric forests      (via sciencedaily.com) 

Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the evolution of the thousands of ant species alive today.

At the end of the dry season: CO2 pulses over Australia      (via sciencedaily.com) 

End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by an environmental physicist. To investigate the carbon fluxes over Australia, the researchers studied atmospheric CO2 measurements. Their analyses show that CO2 emissions spike when heavy rain falls on dried-out soil, thus activating microorganisms in that soil.

AI algorithm unblurs the cosmos      (via sciencedaily.com) 

Researchers adapted a well-known computer-vision algorithm used for sharpening photos and, for the first time, applied it to astronomical images from ground-based telescopes. While astrophysicists already use technologies to remove blur, the adapted AI-driven algorithm works faster and produces more realistic images than current technologies. The resulting images are blur-free and truer to life.

Scallop eyes as inspiration for new microscope objectives      (via sciencedaily.com)     Original source 

Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.

Why are forests turning brown in summer?      (via sciencedaily.com) 

European forests are increasingly turning brown in the course of hot, dry summers. In the scorching summer of 2022, Europe experienced more trees turning brown than ever, with 37% of temperate and Mediterranean forest regions affected. In the three-year meteorological history of low-?greenness events, characteristic weather signals can be found as precursors of the events.
