Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) have developed a new durable plastic that won’t pollute our oceans. The new material is as strong as conventional plastics and biodegradable, but what makes it special is that it breaks down in seawater. The new plastic is therefore expected to help reduce harmful microplastic pollution that accumulates in oceans and soil and eventually enters the food chain.

The experimental findings are published Nov 22 in Science.

Scientists have been trying to develop safe and sustainable materials that can replace traditional plastics, which are non-sustainable and harm the environment. While some recyclable and biodegradable plastics exist, one big problem remains. Current biodegradable plastics like PLA often find their way into the ocean where they cannot be degraded because they are water insoluble. As a result, microplastics—plastic bits smaller than 5 mm—are harming aquatic life and finding their way into the food chain, including our own bodies.

Researchers at Karolinska Institutet and Karolinska University Hospital have developed a microscopy method that enables detailed three-dimensional (3D) RNA analysis at cellular resolution in whole intact mouse brains. The new method, called TRISCO, has the potential to transform our understanding of brain function, both in normal conditions and in disease, according to a new study published in Science.

Despite great advances in RNA analysis, linking RNA data to its spatial context has long been a challenge, especially in intact 3D tissue volumes. The TRISCO method now makes it possible to perform three-dimensional RNA imaging of whole mouse brains without the need to slice the brain into thin sections, which was previously necessary.

“This method is a powerful tool that can drive brain research forward. With TRISCO, we can study the complex anatomical structure of the brain in a way that was previously not possible,” says Per Uhlén, professor at the Department of Medical Biochemistry and Biophysics, Karolinska Institutet, and the study’s last author.

Scientists have developed a method to improve the stability and efficiency of organic light-emitting diodes (OLEDs), a technology used in smartphones, TVs, and other electronic displays.

This advancement utilizes a unique type of molecule that has the potential to extend the lifespan of OLED devices significantly.

The researchers present a novel way to design organic molecules that can maintain their stability and efficiency over time, even in high-stress conditions. The research is published in the journal Nature Communications.

Fresco painting, a technique that dates back to antiquity, involves applying dry pigments to wet plaster, creating stunning artwork that can last for centuries. Over time, however, these masterpieces often face degradation due to delamination, where decorative plaster layers separate from the underlying masonry or structural plaster. This deterioration can compromise the structural integrity of the artwork, necessitating restoration efforts.

Historically, conservators have gently knocked on the plaster with their knuckles or small mallets to assess the condition of the fresco. By listening to the emitted sound, they could identify the delaminated areas needing repair. While effective, this technique is limited both by the conservator’s experience and the small number of people in the world who possess these skills.

Recent research by Joseph Vignola at the Catholic University of America is revolutionizing fresco assessment. Vignola and his team have applied laser Doppler vibrometry to locate delamination in the frescos of Constantino Brumidi in the U.S. Capitol building. This innovative method uses a laser to measure the vibration of a surface, enabling the team to detect delaminated areas based on their unique vibrational characteristics.

In vivo imaging of large-scale neuronal activity plays a pivotal role in unraveling the function of the brain’s circuitry. Multiphoton microscopy, a powerful tool for deep-tissue imaging, has received sustained interest in advancing its speed, field of view and imaging depth. However, to avoid thermal damage in scattering biological tissue, field of view decreases exponentially as imaging depth increases. We present a suite of innovations to optimize three-photon microscopy for large field-of-view imaging at depths unreachable by two-photon microscopy. These techniques enable us to image neuronal activities of transgenic animals expressing protein calcium sensors in a ~ 3.5-mm diameter field-of-view with single-cell resolution in the deepest cortical layer of mouse brains.

Research on moscovium and nihonium shows they are more reactive than flerovium and subject to notable relativistic effects, broadening our understanding of superheavy elements and their potential uses.

An international team led by scientists from GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz, and the Helmholtz Institute Mainz has successfully determined the chemical properties of the artificially produced superheavy elements moscovium and nihonium (elements 115 and 113).

Forget cold plunges. The new flex could soon be human washing machines.

According to one of Japan’s oldest newspapers, an Osaka-based shower head maker called Science has developed a contraption that’s shaped like a cockpit, fills with water when a bather sits in a seat at its center, and measures the person’s pulse and other biological data via sensors to ensure the temperature is just right. It also “projects images on the inside of [its] transparent cover to help the person feel refreshed,” says the outlet.

Dubbed “Mirai Ningen Sentakuki” (human washing machine of the future), the apparatus might never go on sale. Indeed, for now the company’s plans for it appear limited to an expo in Osaka this April, where up to eight people can experience a 15-minute-long “wash and dry” each day after first booking a reservation.
