Deep in Argentina’s Andes Mountains, paleontologists have uncovered the remains of a small dinosaur, giving insight into the early adaptations that characterized sauropod dinosaurs, specifically the extended neck seen in diplodocus.
The fossil, named Huayracursor jaguensis, represents a partial skeleton of a creature that roamed the Earth during the Triassic period, roughly 230 million years ago. It is estimated to have measured around 2 meters in length and weighed about 18 kilograms.
Subsequent sauropods like brontosaurus and Patagotitan would grow to impressive sizes—over 35 meters long and weighing more than 70 tons, marking them as the largest and longest-necked animals in history.
Previously, scientists believed that the ancestors of these long-necked, herbivorous dinosaurs were small, short-necked, and possibly even omnivorous.
At the same time, other smaller sauropods, such as homo jaguensis, measured approximately 1 meter and displayed no signs of elongated neck bones, unlike the newly identified species. This led paleontologists to think that substantial growth in size and neck elongation in sauropods didn’t occur until millions of years later.
The discovery of homo jaguensis at Santo Domingo Creek in northwestern Argentina has prompted a reevaluation of how these dinosaurs developed their iconic long necks, according to Martin Hechenleitner from Argentina’s National Council for Scientific and Technical Research.
“Waila cursor presents a different narrative than the gradual transition model,” Hechenleitner points out. “This is evident since it coexisted with closely related species that were smaller and had relatively shorter necks.”
This dinosaur had a small skull, muscular hind limbs, slender hips, and notably short arms, with relatively large and robust hands compared to other dinosaurs of its era.
This suggests that the traits of increased size and neck elongation emerged early in this evolutionary line, Hechenleitner explains.
“Waila cursor allows us to trace the origins of elongated necks and larger body sizes back to the dawn of dinosaurs in the fossil record,” he says, referencing species like argentinosaurus and Patagotitan, which emerged from a lineage that originated over 100 million years ago, with early bipedal forms measuring just over a meter long and weighing between 10 and 15 kilograms.

A device designed for facial and neck massage suggests it might enhance the brain’s waste removal system and alleviate symptoms associated with conditions like Alzheimer’s disease.
Cerebrospinal fluid (CSF) envelops the brain and inflates it before moving through a network of delicate tubes known as grinft blood vessels. Research on mice indicates that this fluid clears waste produced by brain cells, including proteins linked to diseases like Alzheimer’s and Parkinson’s, such as beta-amyloid.
This has prompted researchers to consider whether increasing CSF flow could promote brain health. However, they note that the grinft vessels, previously only discovered deep within the neck, are difficult to access. Gou Young Koh, from the Advanced Science and Technology Research Institute in Korea, remarks on this challenge.
Recently, Koh and his team identified a network of grinft vessels located just five millimeters beneath the skin on the faces and necks of mice and monkeys. They made this breakthrough by administering fluorescent dyes that label the CSF and imaging the subjects under anesthesia. “We utilized a different kind of anesthesia than was applied in earlier studies. The previous anesthetic blocked the visualization of vessels close to the skin,” Koh explains.
In their effort to determine if massaging these vessels could boost CSF flow, the researchers developed a device with small rods attached to a 1 cm cotton ball. They used it to gently stroke down the face and neck of a 2-year-old mouse for a few months, applying strokes for one minute on younger mice. “A gentle facial and neck massage can compress the liquid and enhance the CSF flow,” Koh states.
After 30 minutes of massage, CSF flow was observed to increase nearly threefold in the brains of the mice compared to their flow prior to the massage. Furthermore, this process seemed to reverse age-related decreases in CSF flow. “After stimulation, the CSF flow in older mice appeared comparable to that of younger mice [who hadn’t received the massage],” Koh elaborates.
In their unpublished findings, the team observed similar outcomes in monkeys. They also identified glymphetic blood vessels in human cadavers, implying that massage could stimulate CSF flow in humans, as suggested by Koh.
However, due to anatomical differences between mice, monkeys, and humans, further investigations are necessary to confirm this, remarks Vesa Kiviniemi from Uru University in Finland. “It’s a slightly different scenario.”
Moreover, it remains uncertain whether increased CSF flow can genuinely mitigate brain aging or offer protection against neurodegenerative conditions like Alzheimer’s. Stephen Prucks of the University of Bern in Switzerland stated that Koh’s team aims to investigate this with mice that exhibit Alzheimer-like traits.
MJust as Christmas isn’t very fun for someone who has to prepare all the presents and prepare dinner, the annual gaming season can be pretty scary for someone who has to put together a shortlist. Every November, I add up all the critically acclaimed games of the year I haven’t played yet, the underground picks I haven’t followed, and the games I loved but forgot about in February. I feel the panic rising. And when all the year-end lists are released, you inevitably realize you missed something anyway.
The Game Awards has announced the nominations for this year’s ceremony, which will be held on December 12th in Los Angeles. (Disclosure: The Guardian is one of 130 voting bodies for this award, but my knowledge and involvement is limited to sending a ballot to Geoff Keighley each year, usually 1-2 (Sorry, Jeff.) But I’m happy to say that one of the top two games with the most nominations is Astro Bot, which received seven nominations. As far as I know, this game doesn’t get enough reviews. (The other was Final Fantasy VII Rebirth, which won six awards and which critics called a miracle of fan service.) Sadly, after many attempts over the years to get into Final Fantasy Despite this, I’m still not immune to Final Fantasy’s charms.
The other contender for Game of the Year is Balatro, the ridiculously obsessive card game that took over my life in January. Elden Ring: Shadow of the Erdtree, an expanded version of the 2022 action role-playing masterpiece. Metaphor: ReFantazio, a very stylish Atlus RPG that I wrote about a few weeks ago. And Black Myth: Wukong was a huge hit this summer, despite huge controversy surrounding its development and release.
It’s a close race, but my prize goes to Shadow of the Erdtree as the Grand Prize. Because this game is especially loved by game critics. However, I would be happy if Astro Bot wins. The dark horse is Baratolo. Everyone I know loses a week or two at that game, but the moment I win, the appeal wears off. However, there is a public vote worth 10% of the weighting. Significantly Black Myth: Wukong is powered by a huge fan base in China.
Neva, rightly nominated for Best Art Direction. Photo provided by: Nomada Studio
Elsewhere, I had the pleasure of seeing Neva, a game about a warrior and his wolf. This one completely made me sob and was nominated for best art direction, best independent game, and confusing game. Games that make an impact category. The latter list is supposed to be “thought-provoking games with pro-social meanings or messages,” but it appears to be an umbrella category of “emotional games.” I’ve played most of the games nominated in that category and a) I don’t see what ties them together, and b) I couldn’t explain what “prosocial” means in this context .
Indika is a dark and fascinating horror-inspired game about a 19th century nun who attacks a Russian Orthodox church. Hellblade II, like its predecessor, depicts the protagonist’s struggle with mental illness. Tales of Kenzera: Zau is about sadness and draws from its creator’s African heritage. “Closer the Distance” is also a song about sadness. Mr. Nevaeh could be interpreted as an environmentalist, and I think there is some loss in that. However, it is impossible to determine what kind of message Life is Strange: Double Exposure has along these lines.
Otherwise, there are few welcome surprises. Creepy exploration puzzler Animal Well was named Best Independent Game, followed by Lorelei and the Laser Eyes, an unpredictable mystery set in an abandoned hotel, and Mosmouth’s 1980s-style game, Ridiculously Generous The same goes for the compilation UFO 50. “Pacific Drive,” a spooky and bizarre fictional road trip about a broken old car that is constantly being repaired and reinforced, also made it onto our list of best debut games. While Prince of Persia: The Lost Crown deserves praise as the best action game, it was a real shame that Dragon’s Dogma II was only named as the best RPG.
and, ofcourse, The Pokémon trading card game Pocket won the award for Best Mobile Game. I’ve been playing it for several hours every day since it was released (and I still No shiny Articuno).
video game chronicle Easy to parse list Among all categories and nominations. But if you think The Game Awards is too commercial, a new awards show is debuting this year. indie game awards which celebrates the “creativity, innovation and passion” of small game developers, has just announced the nominees. Excerpt from the Best Games category: Mouthwashing, a horror game about the final days of the doomed crew of a space freighter. Arranger is an innovative RPG puzzle game. And Nine Sols, an action game that’s like a cross between Hollow Knight and Sekiro, is something I’ve been meaning to try all year.
Please tell us your favorite…
Before I get back to my own ghastly list, I’ll be giving a shout-out to Pushing Buttons readers’ favorite games of 2024, as always, in my newsletter towards the end of December. So go ahead and send it in with a few sentences about what it means to you and see the results in a few weeks.
what to play
Gloomy and strange…the rise of the Golden Idol. Photo: Color Gray Games
I continue to be fascinated ofRise of the Golden Idola gruesome and bizarre detective story that combines logic puzzles, fill-in-the-blank clues, and hidden object games. Each case is presented in the form of a tableau, and although I’m not sure of the style, it reminds me of a version with a certain twist. Grant Wood’s painting “American Gothic”.
The characters are frozen in a loop of seconds at or immediately after the crime, and you have to figure out who everyone is, why they’re there, and what the heck happened. It all connects to a larger story about corruption, deception, and cursed objects. This game often makes me feel very stupid (I don’t have a great brain to figure out names or details), but I still stick with it.

Two micropipettes hold the organism and extend its “neck”
Elliot Flaum and Manu Prakash/Stanford University
Imagine if your neck could stretch long enough to reach your local store while sitting on the couch. That would be a human representation of what a single-celled predator can do. And now, a long-standing mystery has been solved: how that animal can stretch its “neck” to more than 30 times the length of its “body.”
The organism’s cell membrane is folded into a series of folds that can only unfold and fold in one direction. Elliot Flaum Stanford University and her colleagues Manu Prakash They found ways to stretch and fold the paper without it getting tangled. “Most of this came from just playing with paper,” Prakash says.
Lacrimaria Aurore It is a single-celled organism, or protist, that lives in freshwater and hunts prey with a highly extensible neck-like protrusion. Its name means “swan’s tears” after its swan-like neck and teardrop-shaped body.
The cell membrane is very flexible, but it is not elastic and does not stretch. L. Aurore Why their necks stretch so far has remained a mystery since they were first observed under a microscope in the 16th century. “Compared to a lot of other organisms, the neck stretches by an order of magnitude,” Prakash says. “That’s the mystery.”
He and Flaum L. Aurore To solve this mystery, samples taken from the swamp six or seven years ago were studied. Flaum used a variety of techniques to L. Aurore And inside that cytoskeleton is made up of structures called microtubules. “We looked at it in a variety of different ways to try to understand what was going on,” she says.
This means: L. Aurore It is folded into 15 pleats, with each pleat spiralling around the cell to form a helical structure, a folding pattern Prakash calls “curved crease origami,” or “lacrigami.”
but, L. Aurore How can such a vast region of the cell membrane unfold and fold without getting tangled? What Prakash and Flaum discovered is that because the pleats are stabilized by bands of microtubules connected to them, the entire fold cannot unfold at once. Instead, only a single point of the fold can unfold or fold at any one time.
As these points move in parallel along each of the 15 wrinkles, the cell membrane unfolds in an orderly fashion, lengthening the neck. Reversing this process shortens the neck.
“Instead of folding randomly like you would when crumpling a sheet of paper, it has guide rails that help you fold it the same way every time,” Flaum says.
The folding and unfolding of cells is driven by the beating of cilia that cover the entire surface of the cell, Prakash said. Unlike springs, cilia require energy to refold and unfold, whereas cell membranes bend easily and require very little energy.
As far as he knows, no one has discovered this origami technique before. “When I discovered this, I always assumed that someone playing with paper would have discovered this origami,” Prakash says. “It’s so easy.” He says anyone with paper and tape can make it.
“The neck’s ingenious origami-like design makes the cilia effective for high-speed, long-distance hunting,” they write. Leonardo Gordillo and Enrique Cerda At the University of Santiago in Chile Accompanying Articles“The origami-like protrusion mechanism identified by Flaum and Prakash has the potential to inspire new strategies in soft-matter engineering.”
In fact, Prakash and Flaum are currently working on developing a medical robot based on Rakurigami. “If you had a tiny microrobot in a very tight space, and it could suddenly stretch, that would be very useful for microsurgery,” he says. “But we did this research because it’s just beautiful and a mystery to solve. We didn’t expect it to be useful in any way.”

Earlier this year, a patient came to physical therapist Teresa Marco complaining of neck pain. Marco, who is based in New York City, began the interview as usual, asking a series of questions about lifestyle, habits, and attitude. Soon, a person believed to be the culprit appeared. It was a woman’s cell phone.
Marco, who declined to give her name for privacy reasons, said the woman typically used her phone or tablet with her head down on her lap. “She’s going to be very, very bent over, so it’s going to put a lot of strain on her neck,” Marco said.
Marco says he often talks to his patients about how to use their phones. “I don’t think people end up coming to physical therapy because they realize they have a problem with their cell phone,” Marco says. But as she solves problems, it often becomes a focus.
While the negative effects on mental health associated with smartphone use are often discussed, the physical effects can also be significant.serious consequences like Selfie-related injuries and deathscan occur, but chronic problems are much more common, especially in the upper body. This year is research
Using hospital data, they estimated that between 2011 and 2019, hand and wrist injuries caused by cell phone use nearly doubled, reaching about 7,300 cases per year.
“Like [phone] Carolyn Somerich, director of the Human Factors/Ergonomics/Safety Engineering Laboratory at The Ohio State University, said: These sentiments are not new, but according to a Gallup poll, Number of people who reported using a smartphone
“Too much” increased from 39% in 2015 to 58% in 2022. He was 84% most likely to feel this way.
