The fossil of Tyrannosaurus rex known as Stan is on display in a gallery at Christie's auction house in New York City. But not anymore. HE has auctioned.
On October 6, London-based auction house Christie's sold the T.rex for the record amount of 31.8 million dollars, the highest price ever paid at auction for a fossil.
Stan
More than three decades ago, in South Dakota, an amateur paleontologist named Stan Sacrison discovered a titan of ancient Earth: the fossil of a nearly complete Tyrannosaurus rex Nicknamed 'Stan' after its discoverer, the beast was excavated in 1992 and has long been housed at the private Black Hills Geological Research Institute in Hill City, South Dakota.
Is it a good idea to allow these kinds of auctions? Scientists believe no, that the fossil could be lost in this way, since the collector could refuse to show it again, limiting the possibility of repeating results such as measurements of its bones or carrying out new analyzes with more advanced tools and techniques.
Scientists have also expressed concern about the negative effects the sale could have on the study of dinosaurs by incentivizing people to find and sell well-preserved fossils rather than leaving them for paleontologists to study.
Stan's skeleton is undoubtedly one of the best Tyrannosaurus rex specimens ever found.
Stan's journey to the auction block began in 2015, when Neal Larson, a 35 percent shareholder in the Black Hills Institute (and brother of the institute's president, paleontologist Pete Larson), sued the company to liquidate its assets. . A judge ruled in 2018 that Stan had to be auctioned to pay Neal Larson for his participation in the institute.

Yes in The 36 best science books to change the way you see the world we focused on basically Anglo-Saxon authors, Here we are going to focus on some of the best Spanish science communicators.
That doesn't make them better or worse, and it may not make them different in many cases, but perhaps there is something in the writing style, the idiosyncrasy, the culture... that is worth taking into consideration. In any case, by reading them you will also be supporting the increasingly robust health of Spanish dissemination.
Charles Darwin's Nose, by José Ramón Alonso
We are probably facing the most prolific Spanish author of all I know. Choosing one of his books is impossible, because they are all excellent, and he also talks about very, very different things, and with different approaches.
I choose this book because it is the first one I read by him, the one that made me discover him as an author, and it is also ideal to start because it is a kind of compilation of articles on very diverse topics... all of them capable of making you dilate your eyes in amazement.

Nuclear energy will save the world, by Alfredo García
Alfredo is the Tony Stark of nuclear energy, the Tony Manero of radioactivity, the Tony Montana of Greenpeace... well, his name is not Tony, but Alfredo, and he is the already mythical @NuclearOperator on Twitter, and a nuclear operator in real life, specifically at the Ascó Nuclear Power Plant, in Tarragona.
A necessary book. A book that we must protect. Because when it comes to nuclear energy, as in many other issues, information must prevail over indoctrination, fear and Manichean messages, those that fit comfortably on a claim sheet. Because if we want a more ecological world we need a more nuclear world. By the way… Did you know that eating a banana produces a higher radioactive dose than living for a year next to a nuclear power plant?

The left Feng-Shui, by Mauricio-José Schwarz
The scientific method is the most refined procedure to reach levels of empirical knowledge that are difficult to achieve by any other intellectual means.
Many people, however, prefer to be led by hunch, by the fallacy of authority, by amimefunctionism. A weak thought that has taken root, above all, in humanities universities as a result of the May 68 (The Social Text affair highlights the extent of intellectual degeneration we have reached, where what is confusing and cryptic, false, is rewarded over what is expressed clearly and supported by proof and evidence).

The Ignored Kingdom, by David González Jara
Humans feed on more than 5,000 different species, and 18,000 of them have medicinal purposes. The 21% of all of them, however, is in danger of extinction, mainly due to climate change, habitat loss, diseases and invasive species. Plants are fascinating, yes, and David G. Jara He manages to infect us with that fascination through his prose.

May mathematics be with you!, by Cara Grima
Mathematics surrounds us, penetrates us and holds the galaxy together. They are in almost everything you do, from tying your shoes to that selfie in which you looked so good, to auctions, football, vaccines, Game of Thrones or Google. And no one better than the enthusiastic, funny and sparkling Clara Grima to get into them.

Eat without fear, by JM Mulet
We live in times of chemophobia. While we seek the latest technology, in the field of food we reject it, and prefer food "made by grandma", "natural", "organic", "biological". However, natural is not necessarily healthier than chemical. In fact, the difference between natural and chemical is diffuse.
The difference between natural and artificial is diffuse because nature does not feed us. Most societies that live "in nature" have nutritional deficiencies. Most of the things we eat only exist thanks to human intervention. All the species that feed us have been selected, bred and domesticated.

A scientist in the supermarket, by José Manuel López Nicolás
This impressive book is a mundane tour of everything that surrounds us, bringing out with a scientific prism what is worth highlighting, corroborating or questioning. More than a book, furthermore, we are faced with a dialogue in which the author, like a cicerone, shows us all the wonders that surround us on a daily basis. And that everything is, in a way, connected to everything. For example, in one chapter he reaches pull the beet thread, revealing the nature of dyes, or even what all this has to do with the International Space Station.
The dialogue, furthermore, is not with the reader, that too, but with his daughter Ruth, his grandmother and other characters that surround the author and who add, even more, an endearing aspect to the text.
A scientist in the supermarket: A journey through the science of small things (Non-Fiction)
The naked eye, by Antonio Martínez Ron
The first thing you think of when reading this book is “organic.” How well everything is cohesive. It is almost like reading a novel, rich and full of characters, but completely real... a journey that goes from the very origin of the looks to the way in which we try to observe the confines of the universe. Everything we see, everything we can't see, everything we can see. In short, an exquisite book.

Your vitamins are gone!, by Deborah García Bello
Anti-vaxxers tend to be very informed people. There are doctors who even prescribe homeopathy. Pseudoscience courses are taught in universities. And even the most cultured and informed person forms completely wrong ideas about the natural world. And precisely for this reason, books like this one, which explain why there is no difference between white and brown sugar, that electromagnetic waves from cell phones are harmless or that there is no such thing as a healthy glass of wine, resorting to reliable sources such as studies. scientists, should always be on the best-seller podium of any bookstore.

The elaborate bag was made in Mosul, Iraq, around 1300 AD Made of brass, inlaid with gold and silver, it has been identified as one of the earliest surviving examples of a women's handbag.
There is older evidence of wallets, like parts of a 4,200-year-old portfolio found in Germany. But this bag, however, remains relatively well preserved and intact.
Fabric and leather degrade quickly
The bag is a brass vessel inlaid with intricate scenes of court life in gold and silver, and probably belonged to a high-ranking member of the Court.
It was part of the 'Court and Craft: A Masterpiece from Northern Iraq' exhibition held at the Courtauld Gallery in London which focuses on art and craft made in the area around Mosul during the government of the Ilkhanids: Mongol forces under the leadership of Hulagu Khan who conquered much of the Middle East in the mid-13th century.
Wallets made from other materials such as cloth and leather are rare in the archaeological record, not because they were not popular, but because leather and cloth tend to degrade much more quickly than metal, stone or other materials. Preserving wallets after digging can also be tricky.
It is easier to find coins like this one Sutton Hoo, a place located in Suffolk, United Kingdom where remains of a 7th century funerary ship as well as various utensils were found in 1939.
Sutton Hoo has been of vital importance to historians of the Middle Ages as it provided information about that period in England; period that until the discovery was very little documented:
In Europe, in ancient times, the goldsmith's work, the embroidery, the quality of the bag or purse signaled the “social status” of the person who was the carrier.
