X-Men 2 fans: First Look at Nightcrawler and Stryker as brothers in Glenrothan

Brian Cox‘s feature directorial debut “Glenrothan” — billed as his “love letter to Scotland” — has wrapped production, with a first look revealed showing the “Succession” star alongside Alan Cumming in a room full of whisky barrels.

Alongside revealing a first look from the feature, Protagonist Pictures has come aboard for worldwide sales and is set to screen exclusive footage for buyers at the upcoming American Film Market.

Lionsgate, which co-developed the project with London based studio Nevision, has taken U.K. rights on the family drama, which shot in Scotland.

In “Glenrothan,” Donal (Cumming) reluctantly returns to the Scottish Highlands after 35 years in Chicago to make amends with his estranged older brother, Sandy (Cox). Sandy needs Donal to take over the family’s whisky distillery or he will be forced to sell and give up on the family’s legacy. But their reunion forces the brothers to confront the past and the real reason Donal left Glenrothan. Shirley Henderson (“Harry Potter and the Goblet of Fire,” “See How They Run”) and Alexandra Shipp (“Barbie,” “Anyone But You”) also star in the film.

“Glenrothan” is produced by Cox, Neil Zeiger, Crystine Zhang (“Prisoner’s Daughter,” “Lee”), Phin Glynn (“Argentina 1985,” “Kill The Jockey”), Nic Crum (“Book of Love”), James Cabourne and Vladimir Zemtsov (“Club Zero”). The film is co-produced by Nevision and Blazing Griffin Pictures in association with Screen Scotland, Oval-5, Gold Rush Pictures, Head Gear, Infinity Hill and Lionsgate.

“’Glenrothan’ is a poignant, funny and powerful story about the universal themes of family and heritage, set against the stunning backdrops of Scotland and steeped in the world of whisky,” said Protagonist CEO Dave Bishop. “Brian is an undeniable talent, both behind and in front of the camera, and is joined by the exceptional Alan Cumming — as such we are delighted to introduce buyers to this special film when we debut exclusive footage at the upcoming AFM.”

Neil Zeiger, lead producer added: “I have thoroughly enjoyed helping bring ‘Glenrothan,’ Brian’s ‘love letter to Scotland’, to the screen. Working with our incredible cast led by Alan, Shirley and Alexandra, Brian directed the film brilliantly. A universal story, wonderful performances and stunning images define the film. I am confident Glenrothan will compel and captivate audiences wherever in the world they are.”

Protagonist’s current slate includes the Venice, TIFF and San Sebastian selection “Kill the Jockey,” directed by Luis Ortega and recently selected as Argentina’s feature film contender for the 2025 Academy Awards; Samir Oliveros’ TIFF title, “The Luckiest Man in America,” starring Emmy and Golden Globe winner Paul Walter Hauser; the genre-bending comedy “Sister Midnight,” which recently screened at the London Film Festival and was nominated for Cannes’ Camera D’Or; and from directors Guy Maddin, Evan Johnson, and Galen Johnson, the political horror-comedy “Rumours,” which debuted at Cannes before going on to screen at Toronto, San Sebastian, New York and London Film Festivals.

Researchers explain the imaging mechanisms of atomic force microscopy in 3D

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University report the 3D imaging of a suspended nanostructure. The technique used is an extension of atomic force microscopy and is a promising approach for visualizing various 3D biological systems. Atomic force microscopy (AFM) was originally invented for visualizing surfaces with nanoscale resolution. Its basic working principle is to move an ultrathin tip over a sample's surface. During this xy-scanning motion, the tip's position in the direction perpendicular to the xy-plane follows the sample's height profile, resulting in a height map of the surface.

Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope's probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe's tip. The deep learning algorithm developed by researchers at the University of Illinois Urbana-Champaign is trained to remove the effects of the probe's width from AFM microscope images. As reported in the journal Nano Letters, the algorithm surpasses other methods in giving the first true three-dimensional surface profiles at resolutions below the width of the microscope probe tip.

I will not comment on the French beyond saying that some of their 1930's-40's developments in chemical protection come off as almost Baroque in nature. This is a variant of the GEP (Gaz Et Protection) with an added speech diaphragm. The large metal cone in the 3rd image is to direct the user's voice into said cone. Placement on the side of the mask like this aids in the use of a standard telephone handset.

GEPs were one of many, many, many private market civilian respirators manufactured in Europe during the decades surrounding World War 2. Both the carrying case and speech diaphragm on this example appear very visually similar to the respective components of the AFM-34 kit. Not entirely sure if this is because GEP made AFM-34s, or because the patterns and shapes were readily available from a common source and simply purchased by GEP as stock for assembling their masks.

ABSTRACT

Chitosan (CS) and chitin (CH) are two natural polysaccharides. Chitosan with different carboxylation degrees rendering specific zwitterionic properties. In this study, carboxylated chitosan (CCS) and CH polymeric matrix was mineralized to form an hydroxyapatite film.

CS grafted carboxylated group at pH 6, 8, and 10 for products denoted as CCS6, CCS8, CCS10. It was the better degrees of carboxylated, the higher ion conductivity. CCS with zwitterion helped ions movement. Based on thermogravimetric analysis, thermal cracking temperature of the amide group on chitin increased after mineralization. In the TEM image, the PILP behavior was found, and formed hexagonal hydroxyapatite beside chitin. The Young's modulus of hydroxyapatite evaluated by AFM was 5.19±0.06GPa. Meanwhile, Ca/P ratio by EDX analysis was 1.65, similar to bones.

So on the whole nano vehicles thing!

This is something people are researching in the field of nanotechnology! It's a field that combines chemistry, biology, physics (and maths/computer science in some ways but that makes it even more complicated) on the nano scale! Now first what even is nano? Nano refers to the scale of something of 10^-9 in this case it's about sizes but nano is a prefix so eh.

Regardless nanotech is a relatively new field (if you're interested in it there's a lecture called "there's plenty of room at the bottom" by Richard P. Feynman who is often considered the parent of nanotechnology) having only been brought up by the previously mentioned, R. Feynman in 1959 and only really sparking the research field to start in the 1980s.

Anyways so yay small scale science! So nanovehicles: nanovehicles are often bottom up (see: bottom-up = using bricks to build a house vs. top down = carving a house out of rock) produced small "vehicles". They came about because we're looking for ways to transport cargos in a more controlled method than we've been able to mimicking certain biological functions. But the way we've being going about it is by making tiny little car shaped molecules. As you can see in the image below just car shaped with Buckminster fullerene (not actually buckminster fullerene but spherical carbon structures) type wheels.

So basically just like cars work, movement is perpendicular to the axle(usually), however you cannot change the positioning of the axles so this thing can only move forwards and backwards.

Oh quick little side note to even analyse the motion of these things, we have to put them on a surface and depending on the type of motor that can lead to either a caterpillar like motion or just increasingly long tails. But what we can also do is use the tips AFM (atomic force microscopy)or SPM (scanning probe microscopy) and move them with that however that's incredibly expensive Sheesh. We have to do this on a surface because of Brownian motion because these things are so small they'll just move around and about randomly in solution.

Okay back to vehicles. So before I showed a 2 directional transverse moving nanocar. But in the previous ask I said there's nanovehicles that can only spin around themselves. And that's because the Axel's are thusly oriented that any transverse motion it wants to make would be obstructed by another axle. So then it can only do the spinny thing.

See below:

a) shows translational motion such as a nanocar can make.

b) shows rotational motion, such as the nanovehicle I was so excited about.

As well as these images having microscopy which shows how they have moved and where the vehicles are and it's very cool.

And below you can see different types of nanovehicles, 22 & 23 can do translational motion forwards and backwards. 24 can move in a slight circle around a middle point that is not its own center point.

And then you have 25, my beloved, it can only spin in circles <3 its sole purpose is to just spin around and around and around and I think that's somehow so very poetic, the fact you've been made in such a way that your sole purpose cannot be fulfilled but you did prove that yes we can move nanovehicles in more than just the two directions. Also that molecule is a blorbo to me.

i forgot all about this and i have still never been so interested in something i understood next to nothing about thank you for infodumping lulu i heart you
