Optical Microscope

With an abundance of features and a very reasonable price, the Swift SW200 DL Compound Monocular Microscope is a brilliant all-rounder.

Microscopes traditionally resolve only the thin layer of cellular activity within a narrow focal plane. Now scientists have worked out how to squeeze an entire cell and all its molecular machinery into this space.

If you're 65 or older, your risk of pneumonia increases with each passing year. The risk among children under 5 decreases with age.

Long-time Slashdot reader yet-another-lobbyist writes: Phys.org has an article on the recent discovery of super stretchy nanofibers in natural spider silk! The thinnest natural spider silk nanofibrils ever seen are only a few molecular layers thin, about 5 nm. They are too thin to be seen even with...

The 161-million-year-old specimen belongs to a giant species of frog from the Middle Jurassic.

Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hundreds of micrometers find intensive applications.

An intensive MIT summer course teaches students to hone their archaeological research skills through hands-on exploration, including making petrographic thin sections, and mineral analysis of ceramics.

'It's not magic, but it's still very powerful.'

Various imaging methods comprised a kind of "bionic eye" to examine charred scroll.

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.

The most popular words of 2023 were recently released, with AI Large Language Model (LLM) unquestionably topping the list. As a front-runner, ChatGPT also emerged as one of the international buzzwords of the year. These disruptive innovations in AI owe much to big data, which has played a pivotal role. Yet, AI has simultaneously presented new opportunities and challenges to the development of big data.

Ferritic/martensitic steels and austenitic steels are the primary candidate materials for advanced nuclear energy systems. The corrosion resistance of the materials is one of the factors that ensures the safe service of key components. Since the corrosion resistance of materials is highly related to the characteristics of the formed oxide films, it is crucial to investigate the oxide films of candidate materials in…

An essential role of the cornea is to contribute to light focusing on the retina. Its curved shape, and therefore its ability to focus light, must be perfectly stable to ensure a sharp image despite the various shocks and rubs received over the course of a day. The cornea is thus composed of several hundred collagen lamellae stacked one on top of the other with various in-plane orientations.

The authors develop a new oxide-dispersion-strengthened NiCoCr-based alloy using a model-driven alloy design approach and laser-based additive manufacturing, showing how such designs can provide superior compositions using far fewer resources than previous methods.

The process of liquid-to-glass transition is a complex procedure in science, as is the glass-to-liquid transition known as glass melting. In a new report published in Science Advances, Qi Zhang and a research team in physics at the Hong Kong University of Science and Technology in China assembled colloidal glasses via vapor deposition and melted them to observe the glass transition dynamics.

As an indispensable tool for observing the microcosmos, optical microscopy has boosted the development of various fields, including biology, medicine, physics, and materials. However, optical diffraction imposes a spatial resolution restriction on optical microscopy, which hampers exploration of finer structures.

Researchers from the Institute of Botany, Czech Academy of Sciences, have described the symbiotic relationship between fungi and algae that science has largely overlooked until now. The coexistence of algae and corticioid basidiomycetes, which are common in temperate forests, has been given a new name: "alcobiosis." Their work has been published in Scientific Reports.

Scientists have developed an AI method that can pave the way for more medical developments for cancer.
