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.

CTVT and a weird niche theory I fell down the rabbit hole about - giant transforming retroviruses???

This is a story about how a single line on a wikipedia page sent me down a rabbit hole of finding one scientist's fringe theory that's juuuust plausible enough to make me question everything while almost certainly being absolute fucking bunk.

Some background

So, on parts of tumblr at least we all know about Canine Transmissible Venereal Tumour, aka The Immortal Cancer Dog. For those who don't know, it's a cancer dogs get, usually on their junk, that unlike most other cancers, isn't made up of their own cells. The cells are actually all descended from this one dog or wolf that lived like 11,000 years ago and are, arguably, all technically that one dog. A dog that became a single-celled infectious disease.

We have a wealth of genetic, histological and observational evidence for this. As in, we know it what population of canids it came from, we know it's got a weird chromosomal structure compared to normal dogs, we know it's genetically distinct from the hosts. We also know it's not the only one out there: There's a similar thing in Syrian hamsters and also the famous Tasmanian Devil Facial Tumour Disease (DFTD).

Which made me pause when I was reading something on wikipedia about the devil facial tumour and saw a line mentioning that it was now known to be caused by a giant virus, much like CTVT. Which...huh? Oh I hadn't heard that afore.

Giant viruses

Ok so giant viruses are a thing and they're fuckin cool. They're a relatively recent discovery and comparatively huge, i.e. bigger than a bunch of bacteria. They were only discovered in 1981 and we still don't know an enormous amount about them but they're big and have large genomes and because of the way viruses are they're not easy to detect unless you're specifically looking for them.

They show up under microscopy (sometimes) and you can find them with genetic probes but you gotta already be looking for them to see that really. Current research though basically says they're more common than we think, just overlooked, and there's software out there that scans through genomic data to find sequences that might indicate their presence. There's even a possibility that one group might be involved in some cases of pneumonia in humans, though I need to stress that that's extremely not confirmed right now.

The "wait, what?" moment

So I mentioned that it was a line in the wiki article for DFTD that had me going "wait, really?", the line in question was this:

A study found evidence for an infectious agent resembling a giant virus that was capable of turning heathy cells into cancer cells. It was found to be a huge retrovirus with similar viruses being found in human and canine cancer cells.

Big If True.

So of course I check the source, which was a 2020 paper by Lusi et al. titled "A transforming giant virus discovered in Canine Transmissible Venereal Tumour: Stray dogs and Tasmanian devils opening the door to a preventive cancer vaccine".

Hang on, CTVT not DFTD? This is where some alarm bells went off because uh, as mentioned at the start, we know a shit ton about CTVT. Including the fact that it's all one specific dog. Which doesn't fit at all with the idea that it's caused by a virus transforming host cells into cancer cells.

So what fucking gives? What is this research that fully overturns decades of pretty conclusive research to the contrary?

Is this another case of Dr Barbara McClintock? Who spent decades being ridiculed by the scientific community over her wild theory that was, in fact, 100% right even if it seemed to fly in the fact of all prior evidence?

Or is this a Dr Donald I. Williamson situation wherein a scientist with appropriate training is just wildly but extremely vehemently wrong?

#science #genetics #cancer #canine transmissible venereal tumour #devil facial tumour disease #niche science #I'm breaking this up into several sections for readability #stay tuned for more #also feel free to ask any questions about stuff #I'll provide links to things as well but I know tumblr can bury posts with certain links in and idk if researchgate counts

When water vapor meets metal, the resulting corrosion can lead to mechanical problems that harm a machine's performance. Through a process called passivation, it also can form a thin inert layer that acts as a barrier against further deterioration. Either way, the exact chemical reaction is not well understood on an atomic level, but that is changing thanks to a technique called environmental transmission electron microscopy (TEM), which allows researchers to directly view molecules interacting on the tiniest possible scale. Professor Guangwen Zhou -- a faculty member at Binghamton University, State University of New York's Thomas J. Watson College of Engineering and Applied Science -- has been probing the secrets of atomic reactions since joining the Department of Mechanical Engineering in 2007. Along with collaborators from the University of Pittsburgh and the Brookhaven National Laboratory, he has studied the structural and functional properties of metals and the process of making "green" steel.

New analysis reveals the brutal history of the Winchcombe meteorite's journey through space

Intensive new nano-analysis of the Winchcombe meteorite has revealed how it was affected by water and repeatedly smashed apart and reassembled on the journey it took through space before landing in an English sheep field in 2021.

Researchers from dozens of institutions in the UK, Europe, Australia, and the U.S. collaborated on the research. Together, they subjected mineral grains in fragments of the Winchcombe meteorite to a diverse range of cutting-edge analytical techniques.

Their work, which was conducted on a scale more typically reserved for investigating samples returned to Earth by multibillion-dollar space missions, has given them unparalleled insight into the history of the Winchcombe meteorite in the process.

Their analysis has helped them roll back the clock to the meteorite's earliest days as an ice-bearing dry rock, then trace its transformation through the melting of the ice into a ball of mud which was broken apart and rebuilt over and over again.

The Winchcombe meteorite is an unusually well-preserved example of a group of space rocks called CM carbonaceous chondrites, which were formed during the earliest periods of the solar system. They carry minerals altered by the presence of water on their parent asteroid.

Analysis of those minerals within the Winchcombe meteorite will help scientists unravel the answers to questions around the processes which formed our solar system, including the possible origins of the Earth's water.

Unlike most meteorites, which can lie undiscovered for months or years after entering the Earth's atmosphere, the Winchcombe meteorite was recovered within hours of hitting the ground. Members of the public, citizen scientists and the amateur meteorite enthusiast community recognized that rocks had hit the ground and helped scientists to identify the location of samples, aiding their recovery.

The speed of its recovery helped prevent it from being further altered by exposure to the Earth's atmosphere, offering scientists a rare opportunity to learn more about CM chondrites by scrutinizing it down to the atomic level.

In a paper published in the journal Meteoritics and Planetary Science, researchers describe how they explored the complex breccia of the Winchombe meteorite.

A breccia is rock formed from chunks of other rocks cemented together in a structure called a cataclastic matrix. The team's analysis carried out using sophisticated techniques including transmission electron microscopy, electron backscatter diffraction, time of flight secondary ion mass spectrometry and atom probe tomography, showed that the Winchcombe breccia contains eight distinct types of CM chondrite rocks.

The team found that each type of rock has been altered to different degrees by the presence of water, not just between the types of rocks but also, surprisingly, within them. The team found many examples of unaltered mineral grains next to completely altered ones, even down to the nano-scale. For comparison, a human hair is around 75,000 nanometers thick.

The team suggests that the likely explanation for the jumbled nature of the different types of rocks and their extreme variation in aqueous alteration is that the Winchcombe asteroid was repeatedly smashed into pieces by impacts with other asteroids before being pulled back together.

Another significant finding of the analysis is the unexpectedly high proportion of carbonate minerals like aragonite, calcite, and dolomite, along with minerals that have subsequently replaced carbonates, in the samples the team analyzed.

This suggests that the Winchcombe meteorite was more carbon-rich than previously thought and likely accumulated abundant frozen CO2 before it melted to form the carbonate minerals the team observed. The team's analysis could help explain the large carbonate veins that have been observed on the surface of the Asteroid Bennu by NASA's OSIRIS-REx mission.

The study was led by Dr. Luke Daly of the University of Glasgow, who is also the lead author of the paper. Dr. Daly also led the search party which recovered the largest fragment of the Winchcombe meteorite after it was spotted as a fireball streaking across the skies over Gloucestershire on February 28th, 2021.

Dr. Daly said, "We were fascinated to uncover just how fragmented the breccia was within the Winchcombe sample we analyzed. If you imagine the Winchcombe meteorite as a jigsaw, what we saw in the analysis was as if each of the jigsaw pieces themselves had also been cut into smaller pieces, and then jumbled in a bag filled with fragments of seven other jigsaws.

"However, what we've uncovered in trying to unjumble the jigsaws through our analyses is new insight into the very fine detail of how the rock was altered by water in space. It also gives us a clearer idea of how it must have been battered by impacts and reformed again and again over the course of its lifetime since it swirled together out of the solar nebula, billions of years ago."

Dr. Leon Hicks from the University of Leicester and co-author of the study said, "This level of analysis of the Winchcombe meteorite is virtually unprecedented for materials that weren't directly returned to Earth from space missions, like moon rocks from the Apollo program or samples from the Ryugu asteroid collected by the Hayabusa 2 probe."

Paper co-author Dr. Martin Suttle from the Open University said, "The speed which the fragments of Winchcombe were recovered left us with some pristine samples for analysis, from the centimeter scale all the way down to individual atoms within the rocks. Each grain is a tiny time capsule that, taken together, helps us build a remarkably clear view into the formation, re-formation, and alteration that occurred over the course of millions of years."

Dr. Diane Johnson from Cranfield University, a co-author of the paper, added, "Research like this helps us understand the earliest part the formation of our solar system in a way that just isn't possible without detailed analysis of materials that were right there in space as it happened. The Winchcombe meteorite is a remarkable piece of space history and I'm pleased to have been part of the team that has helped tell this new story."

Directing Traffic

Chemical messengers called chemokines are the traffic police of your body, telling cells on the move where to go via a chemokine concentration gradient. Atypical chemokine receptors (ACKRs) on certain cells help create these gradients by binding and engulfing specific chemokines. Three called GPR182, ACKR3 and ACKR4 are located in lymph and blood vessels, and research suggests may be found together in certain microenvironments within organs. However, there’s no comprehensive map of where they are. Researchers now genetically engineer mice with fluorescently-tagged GPR182, ACKR3, ACKR4 and ACKR-specific chemokines to locate them. Fluorescence microscopy revealed unique and shared distribution patterns of these ACKRs in a variety of organs, including the spleen (pictured, ACKR4 in green, GPR182 in red). Meanwhile, fluorescently-tagged chemokines revealed distinct activity zones for ACKR4 and GPR182 in the liver. These mouse models, therefore, provide a useful tool to probe ACKRs in different organs and microenvironments.

cactus ⇢ something you’re currently learning (about)?

Fun answer: woodworking! I'm working on building myself a bench so I can start building myself some simple furniture and boxes. So far it mostly seems to boil down to "sharpen your chisel", but its a lot of fun!

Boring answer: mortgages. Might be buying a house soon.

Extremely specific technical answer: photo-induced atomic force microscopy; I'm potentially starting on a project for a conference next year, so I need to figure out the key differences between PIAFM and scanning probe microscopy.

Thanks for the ask!

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
