Nanoparticles that can light up the lymph node cancer cells otherwise undetectable by MRI      (via sciencedaily.com)     Original source 

Researchers have developed a new nanoparticle that can 'hitch a ride' on immune cells, or monocytes. Because of its tiny size, the particle can tag along directly into lymph nodes and help metastasis show up on MRIs where it would otherwise be too hard to detect. The process offers game-changing benefits for the early detection of cancer metastasis in the lymph nodes. While previously, metastasis could only be assessed by an increase in lymph node size; the new particles could lead to MRI contrast agents that can highlight metastatic cells in lymph nodes that may otherwise appear normal.

Exploring the effect of ring closing on fluorescence of supramolecular polymers      (via sciencedaily.com)     Original source 

The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.

Scientists study the behaviors of chiral skyrmions in chiral flower-like obstacles      (via sciencedaily.com)     Original source 

Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges. Scientists have recently studied the random walk-behaviors of chiral skyrmions by simulating their dynamics within a ferromagnetic layer surrounded by chiral flower-like obstacles. The simulations reveal that the system behaves like a topological sorting device, indicating its use in information processing and computing devices.

New AI tool discovers realistic 'metamaterials' with unusual properties      (via sciencedaily.com)     Original source 

A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue: These extraordinary objects are already made from 'metamaterials'. Researchers have now developed an AI tool that not only can discover such extraordinary materials but also makes them fabrication-ready and durable. This makes it possible to create devices with unprecedented functionalities.

Molecular manganese complex as superphotooxidant      (via sciencedaily.com)     Original source 

Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All these photocatalysts require high energy light for excitation and their oxidizing power has not yet been fully exploited. Furthermore, precious and hence expensive metals are the decisive ingredients in most cases. A team of researchers has now developed a new molecular system based on the element manganese. Manganese, as opposed to precious metals, is the third most abundant metal after iron and titanium and hence widely available and very cheap.

New PET tracer detects inflammatory arthritis before symptoms appear      (via sciencedaily.com)     Original source 

A novel PET imaging technique can noninvasively detect active inflammation in the body before clinical symptoms arise, according to new research. Using a PET tracer that binds to proteins present on activated immune cells, the technique produces images of ongoing inflammation throughout the body, such as rheumatoid arthritis. This makes it easier for physicians to correctly diagnose and treat patients.

Heart organoids simulate pregestational diabetes-induced congenital heart disease      (via sciencedaily.com)     Original source 

An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report. The organoids recapitulate hallmarks of pregestational diabetes-induced congenital heart disease found in mice and humans. The findings also showed that endoplasmic reticulum (ER) stress and lipid imbalance are critical factors contributing to these disorders, which could be ameliorated with exposure to omega-3s.

BESSY II: Molecular orbitals determine stability      (via sciencedaily.com)     Original source 

Carboxylic acid dianions (fumarate, maleate and succinate) play a role in coordination chemistry and to some extent also in the biochemistry of body cells. A team has now analyzed their electronic structures using RIXS in combination with DFT simulations. The results provide information not only on electronic structures but also on the relative stability of these molecules which can influence an industry's choice of carboxylate dianions, optimizing both the stability and geometry of coordination polymers.
