Some protective resin coatings may damage metal artifacts
Conservators and museum technicians protect precious archaeological metal objects, such as tools and weapons, with clear coatings, leaving preserved and unobstructed views of these detailed treasures. However, researchers have reported that some of the resins used for these coatings react with iron-containing metals and can cause damage. The team developed a non-invasive fluorescence imaging strategy that reveals early signs of these damaging chemical reactions and confirmed its utility on ancient artifacts.

Scientists have found a way to 'tattoo' tardigrades
If you haven't heard of a tardigrade before, prepare to be wowed. These clumsy, eight-legged creatures, nicknamed water bears, are about half a millimeter long and can survive practically anything: freezing temperatures, near starvation, high pressure, radiation exposure, outer space and more. Researchers took advantage of the tardigrade's nearly indestructible nature and gave the critters tiny 'tattoos' to test a microfabrication technique to build microscopic, biocompatible devices.

Material? Robot? It's a metabot
The invention is a metamaterial, which is a material engineered to feature new and unusual properties that depend on the material's physical structure rather than its chemical composition. In this case, the researchers built their metamaterial using a combination of simple plastics and custom-made magnetic composites. Using a magnetic field, the researchers changed the metamaterial's structure, causing it to expand, move and deform in different directions, all remotely without touching the metamaterial.

Researchers use machine learning to engineer 'bespoke enzymes' for gene editing
Genome editing has advanced at a rapid pace with promising results for treating genetic conditions -- but there is always room for improvement. A new paper showcases the power of scalable protein engineering combined with machine learning to boost progress in the field of gene and cell therapy. In their study, authors developed a machine learning algorithm -- known as PAMmla -- that can predict the properties of about 64 million genome editing enzymes. The work could help reduce off-target effects and improve editing safety, enhance editing efficiency, and enable researchers to predict customized enzymes for new therapeutic targets.

Transformable flat-to-shape objects created using sewing technology
Researchers introduced a novel method for fabricating functional flat-to-shape objects using a computer-controlled sewing machine. The team's method uses the sewing machine to stitch pockets between layers of fabric, and stiff panels are inserted into the pockets. Multiple fabrics types can be used, ranging from muslin for heavy-duty applications to more delicate fabrics for decorative purposes. The materials can also be customized on a panel-by-panel basis to adapt to each object's needs. The researchers demonstrated how the materials can be chosen to support a variety of functional goals, such as using thicker plywood for a human-weight supporting chair and custom LED panels with sheer fabric for a functional lamp. Additionally, The technique also allows for additional mechanisms such as cords, magnets, and hook-and-loop fasteners to direct and stabilize flat-to-shape transitions.
