It works by coiling a long DNA double helix into concentric rings that stack on each other to form the contours of the object, like using coils of clay to make a pot. To make the structures stronger, the team also made it possible to reinforce them with additional layers for increased stability. But the researchers say these are more than mere nano-sculptures.

"How nanoscale patterns of antigens are recognized by immune cells is a very poorly understood area of immunology," Bathe says. "Attaching antigens to structured DNA surfaces to display them in organized patterns is a powerful way to probe that biology." Another key application is designing light-harvesting circuits that mimic the photosynthetic complexes found in plants. To achieve that, the researchers are attaching light-sensitive dyes known as chromophores to DNA scaffolds.

Shell buckling for programmable metafluids

The connections are all too tight but if you're willing to file things down they're pretty nice. I've given them to the box set toy deco versions now and they really complete the look. And this is more of a me-problem, but you also can't have the 115 feet on Dead End and use the Matrix Workshop gun at the same time. I'd say it's more of a "whoever's upgrade was designed later" problem.I'm kinda bummed out about that too. But I prefer to use the weapons over the toes, so…Otherwise, I love MW made these weapons.

To achieve that, they developed a new mathematical approach to the process of routing the single-stranded scaffold through the entire structure to form the correct shape. The resulting computer program can take any free-form drawing and translate it into the DNA sequence to create that shape and into the sequences for the staple strands. Others later used a similar approach to create complex three-dimensional DNA structures. However, all of these efforts required complicated manual design to route the scaffold through the entire structure and to generate the sequences of the staple strands. In 2016, Bathe and his colleagues developed a way to automate the process of generating a 3-D polyhedral DNA structure, and in this new study, they set out to automate the design of arbitrary 2-D DNA structures. This new upgrade kit brings you several new pieces to improve the main Menasor body frame.

Granted the CW designs didn't always lend themselves to being better integrated but almost all had a similar shape overall being wide and flat or thin and rounded. So I'm going to wait and see now before committing to a set for Volcanicus. There's at least something going on with the torso on this set in order for the sword to be stored on the back like that. So it will be interesting to see what else they do other than the feet and lower arms like the other sets. As I discussed in The Cell’s Design—and elsewhere—one of the most provocative arguments for intelligent design centers on the recognition that DNA (and other biomolecules) is an information-based system. Common, everyday experience teaches that information derives solely from the activity of human beings.

It features a stepped seating area and wooden details that unify it with the other facilities. "Each platform is a multicultural study where one can read, practice calligraphy from stone rubbings and, in the future, access e-books," said the studio. Cabinets containing books have been built into the large steps of the quarry, with its tapering form creating naturally sheltered areas for reading. "The project is an ecological improvement to mend the interrupted nature," the studio told Dezeen. "The reuse of these abandoned quarries reconnects the local community with its thousand-year history and heritage." According to the studio, this also challenges the "over-designing" of popular tourist areas in rural China.

It's kind of lame that DNA included two identical blasters instead of mirroring them properly for right and left (though, from a lot of angles, the difference isn't super obvious). I kind of wish that the tab to secure the melee weapons to Prime's back wasn't a separate part, and I think one axe and one sword were probably enough. I get the feeling that DNA included the extras just to jack up the price of a kit, and that price is kind of a sore spot since the upgrade costs more than the figure itself. Also jacking up the price are some blast effects that are compatible with the blasters but makes them look like shitty squirt guns and a slug of Noah Diaz that I don't think anybody asked for.

Right now, proteomics relies on incredibly expensive and complex instruments. If we could develop complementary single-molecule approaches based on accessible nanoscale methods, we could solve current challenges and democratize these amazing capabilities. Other possible applications for the DNA structures include using them to help organize macromolecular protein assemblies found in cells, so that they can be more easily imaged with high-resolution cryo-electron-microscopy. MIT’s new MIT.nano facility has two such microscopes, which can be used to reveal the fine details of tiny structures.

The shapes, which range from 10 to 100 nanometers in size, can remain stable for weeks or months, suspended in a buffer solution. Researchers have been experimenting with DNA as a construction material since the 1980s. The first 3D shapes were simple cubes, pyramids, soccer balls -- geometric shapes with coarse and blocky surfaces. But designing structures with curved surfaces more akin to those found in nature has been tricky.

Z Stacks of droplets with a z spacing of 1 μm were acquired with an Andor XD spinning disk confocal microscope equipped with the ×60 objective. As DNA hybridization is thermally reversible, we tested how heating affects the mechanics of pre-assembled DNA-crosslinked networks. This indicates that the thermal dependence of A′ is due to the formation (during cooling) and dissociation (during heating) of DNA crosslinks. Live imaging of assembled A′ bundles at 60 °C (above Tm; Supplementary Video 2) revealed Brownian-type fluctuations that were arrested after cooling. This suggests that heating destabilizes the crosslinks between thin bundles, reducing Gω.

To examine the temperature dependence of the rheological properties, temperature sweep experiments were performed at a frequency of 1 Hz with 0.5% strain. For A′, the temperature was changed from 25 °C to 40 °C back to 25 °C. Then the temperature was changed from 25 °C to 50 °C back to 25 °C. For A-A′, the temperature was changed from 25 °C to 50 °C back to 25 °C. For A-B-C, the temperature was changed from 25 °C to 40 °C back to 25 °C and then from 25 °C to 50 °C back to 25 °C. The mechanical properties of cytoskeletal actin bundles vary by orders of magnitude depending on the bundle length, diameter, crosslinking protein type and concentration47.
