Lead-vacancy centers in diamond as building blocks for large-scale quantum networks      (via sciencedaily.com)     Original source 

A lead-vacancy (PbV) center in diamond has been developed as a quantum emitter for large-scale quantum networks by researchers. This innovative color center exhibits a sharp zero-phonon-line and emits photons with specific frequencies. The PbV color center stands out among other diamond color centers due to its ability to maintain optical properties at relatively high temperatures of 16 K. This makes it well-suited for transferring quantum information in large-scale quantum networks.

Gentle defibrillation for the heart      (via sciencedaily.com)     Original source 

Using light pulses as a model for electrical defibrillation, scientists developed a method to assess and modulate the heart function. The research team has thus paved the way for an efficient and direct treatment for cardiac arrhythmias. This may be an alternative for the strong and painful electrical shocks currently used.

This alloy is kinky      (via sciencedaily.com)     Original source 

Researchers have uncovered a remarkable metal alloy that won t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. Unlike most materials, the new alloy keeps its shape and resists cracking at both high and low temperature extremes, making it potentially suitable for demanding applications like high-efficiency aerospace engines.

Switching off the light to see better      (via sciencedaily.com)     Original source 

Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of images that surpassed the conventional resolution limit, and it may be useful for further study of cell clusters and other biological systems.

Light show in living cells      (via sciencedaily.com)     Original source 

Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.

From defects to order: Spontaneously emerging crystal arrangements in perovskite halides      (via sciencedaily.com)     Original source 

A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = formamidinium), they observed that ordered columnar defects appeared in the stacked crystalline layers, taking up one-third of the lattice space. These findings could pave the way to an innovative strategy for adjusting the properties of hybrid perovskites, leading to practical advances in optoelectronics and energy generation.

E-tongue can detect white wine spoilage before humans can      (via sciencedaily.com)     Original source 

While the electronic tongue bears little physical resemblance to its namesake, the strand-like sensory probes of the 'e-tongue' still outperformed human senses when detecting contaminated wine in a recent study. In a recent experiment, the e-tongue identified signs of microorganisms in white wine within a week after contamination -- four weeks before a human panel noticed the change in aroma. This was also before those microbes could be grown from the wine in a petri-dish. Winemakers traditionally rely on these two methods, sniffing the wine and petri-dish testing, to identify potential wine 'faults' or spoilage.

New tagging method provides bioadhesive interface for marine sensors on diverse, soft, and fragile species      (via sciencedaily.com)     Original source 

Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the quality of data collection. A newly developed soft hydrogel-based bioadhesive interface for marine sensors, referred to as BIMS, holds promise as an effective, rapid, robust, and non-invasive method to tag and track all sorts of marine species, including soft and fragile species. The BIMS tagging, which is also simple and versatile, can help researchers better understand animal behavior while also capturing oceanographic data critical for helping to better understand some impacts of climate change and for resource management.

Next-generation treatments hitch a ride into cancer cells      (via sciencedaily.com)     Original source 

Researchers found that a new activator called L687 induces cancer cells to accept delivery of antisense oligonucleotide (ASO) drugs. These drugs can treat cancer by blocking the transfer of messages from genes that encourage cancer growth. Previous methods to deliver ASOs into cells had only limited success. This research will help accelerate the development and delivery of novel ASO cancer therapies.

Millions of gamers advance biomedical research      (via sciencedaily.com)     Original source 

4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.
