Generating stable qubits at room temperature      (via sciencedaily.com)     Original source 

Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.

Is there a common link between the physical and social worlds? Two brothers think so      (via sciencedaily.com)     Original source 

A Rutgers biophysical chemist and his brother, a political scientist on the West Coast, have joined intellectual forces, realizing a long-standing dream of co-authoring an article that bridges their disciplines involving cells and society. In their paper, they have proposed that powerful parallels exist between the microscopic, natural world of cells and molecules and the human-forged realm of organizations and political systems.

Researchers step closer to mimicking nature's mastery of chemistry      (via sciencedaily.com)     Original source 

In nature, organic molecules are either left- or right-handed, but synthesizing molecules with a specific 'handedness' in a lab is hard to do. Make a drug or enzyme with the wrong 'handedness,' and it just won't work. Now chemists are getting closer to mimicking nature's chemical efficiency through computational modeling and physical experimentation.

Towards more accurate 3D object detection for robots and self-driving cars      (via sciencedaily.com)     Original source 

Robots and autonomous vehicles can use 3D point clouds from LiDAR sensors and camera images to perform 3D object detection. However, current techniques that combine both types of data struggle to accurately detect small objects. Now, researchers have developed DPPFA Net, an innovative network that overcomes challenges related to occlusion and noise introduced by adverse weather. Their findings will pave the way for more perceptive and capable autonomous systems.

Bottled water can contain hundreds of thousands of previously uncounted tiny plastic bits      (via sciencedaily.com)     Original source 

In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits, these particles are being consumed by humans and other creatures, with unknown potential health and ecosystem effects. One big focus of research: bottled water, which has been shown to contain tens of thousands of identifiable fragments in each container. Now, using newly refined technology, researchers have entered a whole new plastic world: the poorly known realm of nanoplastics, the spawn of microplastics that have broken down even further. For the first time, they counted and identified these minute particles in bottled water. They found that on average, a liter contained some 240,000 detectable plastic fragments -- 10 to 100 times greater than previous estimates, which were based mainly on larger sizes.

Asbestos: The size and shape of inhaled nanofibers could be exclusively responsible for the development of pulmonary fibrosis      (via sciencedaily.com)     Original source 

The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fiberglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study conducted on glass nanofibers.
