Confocal microscopy time lapse of peptide fibres for bending stiffness calculations. 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.

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.

Fmoc-Phe-OH, N,N′-diisopropylcarbodiimide, trifluoroacetic acid (TFA), triisopropylsilane (TIPS) and triethylammonium acetate (TEAA) were purchased from Sigma-Aldrich. Ethyl cyano(hydroxyimino)acetate (Oxyma Pure) and piperidine were purchased from VWR. Dibenzocyclooctyne-sulfo-N-hydroxysuccinimidyl ester (DIBAC-sulfo-NHS) was purchased from Sigma-Aldrich; it was dissolved in dry DMSO to a final concentration of 100 mM and stored at −20 °C before use. All DNA strands (including amine-modified strands) were purchased from IDT; they were dissolved in water to a final concentration of 1 mM or 100 μM and stored at −20 °C before use. Fmoc-FF-OH and Fmoc-Phe-Phe-PEG2-Lys(FITC)-NH2 were purchased from Bachem. On April 25, 1953, a group of researchers published papers in Nature detailing the molecular structure of DNA, the building block of the genetic code of all organisms, for the first time.

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.
This can be attributed to the varying filament lengths of the different DNA crosslinkers, as FF fibres are the longest and require the highest bending energy for encapsulation in cell-sized confinement. The solidity (measure of compactness) of the FF lipid droplets remained close to 1 for 2 h at 50 °C, indicating a solid and compact structure (Fig. 6f(i)). Prolonged heating sharply reduced the solidity of the FF droplets to ~0.7 (less compact) due to fibre protrusion, minimizing local membrane deformations and releasing the fibre-bending energy62. In contrast, the fibres in A′ and Am-A′m droplets do not protrude, probably due to their shorter length (lower bending energy of fibres), generating smaller local membrane deformations (Supplementary Fig. 31). For small FF droplets (≲25 µm), which are globally deformed before heating (Supplementary Fig. 42f), fibres protruded earlier in the heating process (Supplementary Video 13) and the solidity analysis revealed enhanced protrusion.

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.

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.

"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.
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.
For smaller Am-A′m droplets, no deformations were observed, probably due to the shorter fibre length (Supplementary Fig. 42f and Supplementary Video 15). Recently, engineering of the synthetic cytoskeleton has been proposed as a pathway to generate artificial cells11. While various building blocks form filaments and networks in the bulk, including polymers12, small molecules13, carbon nanotubes14, peptides13,15 and DNA16,17,18, assembly in cell-like confinement has so far mainly relied on DNA material19,20,21,22,23.
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.
