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.

Innovative antiviral defense with new CRISPR tool      (via sciencedaily.com)     Original source 

The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate. Scientists have devised a solution: Cas13d-NCS. This new molecular tool allows CRISPR RNA molecules that are located within the nucleus of a cell to move to the cytoplasm, making it highly effective at neutralizing RNA viruses. This advancement opens doors for precision medicine and proactive viral defense strategies.

While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.
