A New Jersey neighbor kept the remains of a meteorite in glass jars. This gesture has given us new clues about the origin of life on Earth

by

On July 19, 2026, a meteorite shook New York City: Ferrán Torres’ goal in the 106th minute, against the Argentina team. Well, okay, it wasn’t a meteorite, although for many, the emotional shock wave was comparable to the physical shock wave left in its wake by the meteorite that did shake the city of the Statue of Liberty two years earlier, on July 16, 2024. That asteroid fragment broke up 35 kilometers away, releasing a multitude of debris that fell unseen in various parts of the state of New Jersey. One of them, weighing almost 1 kg, went through the roof of a house in the town of Hillsborough. Two years later, an international team of scientists has published the analysis of the composition of the New York meteorite. It is a very rare type of meteorite, known as a CM ½ carbonaceous chondrite and is characterized, among other things, because it can provide a window into the history of the origin of life on Earth. A very rare type of meteorite. The meteorite is a carbonaceous chondrite. That is, a fragment of a primitive objectrich in carbon, which can be associated with different organic molecules. Generally, these meteorites are classified according to their degree of aqueous alteration. The lower the number, the more water has altered its structure in the original object from which it came. The carbonaceous chondrites that have fallen most abundantly on Earth in the form of meteorites are those of type CM 2. 20 have been documented. Of type CM 1, none are known. However, there is an iconocidal range such as CM ½, which is in the middle and had been previously found, in a meteorite that fell in 2020 in Indonesia. The Hillsborough meteorite, therefore, has been the second, but also the best preserved, thanks to the quick intervention of the owner of the house in which it fell. A hole in the roof and the smell of sulfur. The Hillsborough meteorite is actually one of many fragments left after a larger rock broke apart 35 kilometers up. He fell with such force that he managed to break through the ceiling, landing in the main bedroom of the house. Its owner stated that, upon entering his room, he saw a hole in the ceiling and he smelled a strong smell of sulfur. He then found his bed and carpet covered in debris and black dust. He decided to put on some gloves and store all the debris in glass jars with aluminum foil. Thanks to their quick and scrupulous action, the scientists were able to analyze the meteorite as intact as possible. Following the path of the Hillsborough meteorite. Before falling in Hillsborough, the meteorite crossed the skies of New York and other cities in the United States. 60 observersspread across the states of New York, New Jersey, Connecticut, Rhode Island and Pennsylvania, reported seeing them to the American Meteor Society. Additionally, 16 others in New York and New Jersey said they felt the shock wave. Taking into account all these testimonies, plus the detections from astronomical observatories, it was possible to follow its trajectory to the lower asteroid belt. Ingredients for life. We have already seen that this was a CM ½ emteorite. However, a more detailed analysis of the meteorite allowed us to find some fragments of CM1 rich in salts inside. This indicates that it was formed in some area of ​​the surface of the parent asteroid where liquid water evaporated and salts were concentrated. It is known that the high concentration of salt in saline fluids can create molecules crucial for life on Earth. In fact, many studies suggest that, in the past, CM carbonaceous chondrites delivered to Earth some of the ingredients that gave rise to life. That’s why the Hillsborough meteorite is so interesting. At the moment, it has been seen to have 1.8% by weight of carbon and 0.07% of nitrogen, in addition to carbon and nitrogen isotopes typical of CM type meteorites. A more detailed analysis of the latter will help understand the extent to which these objects helped life proliferate on our planet. The owner of the house was not aware when he saw that hole in the roof that it not only had a huge leak. I was also looking at a window to the past.

The oldest human remains in Antarctica are more than 200 years old. The problem is that it doesn’t make any sense.

by

In 1912, the British explorer Robert Falcon Scott He arrived at the South Pole convinced that he would be the first to set foot on it. There he found an unexpected surprise: a tent with the Norwegian flag and a letter from Roald Amundsen They showed that someone had been more than a month ahead of him. The history of polar exploration is full of “firsts” that, with the passage of time, have ended up being revised. The remains that should not be there. Antarctica has never had a permanent population. When humans arrived on its shores, it was already a continent too cold and isolated to be inhabited without modern technology. That is why it is so disconcerting that the oldest human remains found there belong to a deceased woman. between 1819 and 1825just when the first documented explorations of the continent were just beginning. A half-buried skull. The discovery occurred in 1985, when the Chilean biologist Daniel Torres Navarro found a skull partially buried on Yámana beach, Cape Shirreff. Years later they appeared other scattered bonesincluding a femur, which probably belonged to the same person. Analysis suggests that she was a young woman, possibly of Chilean origin, whose death occurred sometime between 1819 and 1825. The chronology turns the discovery into a puzzle. The problem is not only who that woman was, but when she died. The first confirmed observation of Antarctica is usually attributed to the Russian expedition of Fabian Gottlieb von Bellingshausen in 1820. If the dating of the remains is correct, the woman lived exactly during the period in which the first expeditions were just beginning to approach the continent. This temporal coincidence makes it extremely difficult to explain how he ended up in one of the most inhospitable regions on the planet. The first Russian expedition to Antarctica (1819-1821) The hypotheses and the mystery. Researchers are considering several possibilities. The first suggests that he could be part of a group of seal hunters from the 19th century who abandoned it after his death. The second proposes that she died on board a ship, was buried at sea (as was common then) and that the currents, together with scavenging birds, They would later disperse their remains to the beach where they were found. None of these explanations have been proven and, four decades after the discovery, new remains have still not appeared that would allow us to reconstruct what happened. The alternative. While that enigma remains open, another study invites us to review another of the great certainties about the continent. Researchers at the University of Otago maintain that Polynesian sailors, and in particular the explorer Hui Te Rangiorathey were able to reach the Antarctic waters already in the 7th century. The hypothesis is supported by Maori oral traditions which describe a frozen ocean, large masses of ice and a dark, fog-covered landscape, descriptions that some specialists consider compatible with the Southern Ocean. Between legends and archaeological evidence. The authors of the study make it clear that these traditions do not constitute a definitive demonstration that the Maori ever contemplated Antarctica. However, they do question the idea that the history of the continent began exclusively with European expeditions of the 19th century and claim the role of indigenous traditions in the reconstruction of the great oceanic explorations. If this interpretation ends up being confirmed, the first human contact with the southern tip of the planet would be more than a thousand years ago to what usually appears in history books. Two investigations that force us to look with different eyes. The two studies They speak of very different times, but they converge on the same conclusion: we still know surprisingly little about the first human contacts with the most isolated continent on Earth. One suggests that Polynesian navigators could have arrived much earlier than previously believed. The other remembers that the oldest human remains found there belong to a woman whose presence remains extraordinarily difficult to explain. Two centuries after his death, the biggest mystery is not who he was, but why he appeared on the only continent where, quite simply, no one expected to find it.

We know that the inhabitants of a Roman site in Aragon loved wine and games. A mystery remains: why they vanished

by

When we think of ancient Rome, the first image that comes to mind is that of patricians in togas, the Colosseum, legionnaires and heroes gathered in the Senate. That however is only one part of the Empire. The “Rome of marble”, as the archaeologist Ángel A. Jordán recently summarized it in an interview with The Newspaper. Another, equally important and much less known, is the “Rome of clay”, that formed by people who lived far from the metropolis and dedicated their days to working, drinking and playing, went hungry, loved and mourned their dead. That last Rome is the one that Jordan and his companions are discovering little by little in Barker Heada deposit of Five Villasprovince of Zaragoza. In a place in Aragon… It may not be the best-known site in Spain, but Barker Head has proven to be a box of surprises for archaeologists interested in the history of Aragon. Located in the pre-Pyrenean foothills, near Sofuentes, its land was occupied for centuries and played a key role in the road which Augustus ordered to be built and toured the area. Hence since 2016 Researchers have carried out several campaigns to peer into the secrets of a population that, it is estimated, covered 19 hectares and extended from the late bronze age until late antiquity, between the centuries VI and IX AD., a period that has left a good handful of vestiges. Last year, for example, was announced the discovery of a Roman road. Why is it news? Because after eight campaigns, a new excavation has just been launched at the site. He revealed it a few days ago The Aragon Newspaperwho in the process chatted with the project director, Angel A. Jordanabout the objective that the team has set for this year: to clarify why the population declined, something difficult to understand with the data they have collected so far. “It is a city that a priori has water because it is located in a place where there are many springs, it is a privileged area with very good agricultural land… It is a great mystery why the city stopped being inhabited. In the 7th century it no longer exists,” details the expert The chronicle of Cabeza Ladrero can therefore extend from the IX or VIII BC until late in our era, although it is believed that it reached its period of splendor during the Roman era. One unknown, two theories. Although the excavations will (hopefully) clarify the mystery, Jordán and his team already start with some theories on the table. One is that the settlement succumbed to external attacks. “Last year the excavation began to give us curious elements. Small remains are appearing that indicate the presence of fire, ashes are appearing in different parts of the street and that makes us think that it could have been abandoned due to some violent event,” admits in The Newspaper. “Taking into account that the city does not reach the 7th century and that there are signs of destruction, we could still be facing some type of attack, especially from the Bagaudas, rebel groups that acted in the Ebro valley during the 5th and 6th centuries and that looted several cities in the region,” apostille the expert The other suspect. The second hypothesis is that it was the disease that killed the locals. As remember Jordanit is known that in the 6th century there was “a brutal epidemic of the Black Death” that had devastating consequences. “It is estimated that in many parts of the empire up to 25% died,” says the director of the archaeological project before remembering that there is evidence of another phenomenon: a transfer of population to The Bañalesa Roman settlement located not far from Cabeza Ladrero and which became a prosperous town. The “Rome of clay”. Beyond its geopolitical relevance, its role in the road system or the details of its chronicle, there is another reason why Cabeza Ladrero is so special: it offers us a window into the “Rome of clay”which completes the image of “marble Rome” that cinema usually conveys and has formed the cliché of the empire. After all, at the Aragonese site archaeologists have found much more than vials and ancient milestones. Pitchers and board games. During their excavations, researchers have found jugs that tell us about his love of drinking and several tokens that, experts believe, could have been part of an ancient board game. “They were people who lived, got drunk and robbed each other; but they also loved and we have been able to see that very well in the necropolis,” Jordan says in The Newspaper. “Indeed, they played because they had to have fun and, if not, they were bored out of their minds. They organized tournaments and the kids had their toys.” Images | Wikipedia 1 and 2 Via | The Aragon Newspaper In Xataka | Under an institute, Rome has found something impressive: a perfectly preserved “domus” from the 2nd century

23 years ago a Boeing 727 left the runway without authorization. What happened next remains an enigma

by

A commercial airliner should not disappear like this. We are talking about one of the largest and most monitored machines in the transportation industry, with flight plans, airport controls, maintenance records and normally traceable components. That is why the case of Boeing 727 N844AA It’s so hard to close. According to Aviation Safety Networkthe aircraft took off from the Quatro de Fevereiro international airport, in Luanda, on May 25, 2003, around sunset and without the corresponding authorization. Since then there has been no confirmed landing, no identified remains or a definitive explanation. Before becoming a mystery, N844AA had led a much more conventional life. Washington Post explains that it was a Boeing 727-223 built in 1975, delivered to American Airlines and removed from the airline’s fleet towards the end of the summer of 2001. Then came the strange twist: the plane was converted to transport diesel within Angola, with seats removed and large internal tanks installed in the cabin. The idea was to supply operations linked to diamond mines in areas difficult to serve by road, but the plan soon went awry. The operation began to accumulate problems. The fuel transport project was met with unpaid invoices, problems with stolen passports, security lapses and questions about who really controlled the plane. By May 2002, the crews had already left and the original plan was practically undone, but the 727 was still there, immobilized at the Luanda airport. Almost a year later Ben Charles Padilla appearedsent by Aerospace Sales & Leasing for try to recover an aircraft that it could still have value as an asset, even if it fit increasingly worse into its previous life. A stranded plane, an unauthorized departure and too many open questions Padilla is a central figure because most stories place it inside the plane at the time of departure. There is also an important nuance: he was a certified flight engineer, aeronautical mechanic and private pilot, but not a qualified captain for a Boeing 727. That model required a crew of three people, with two pilots and a flight engineer dedicated to managing systems. John Mikel Mutantu is also mentioned as a possible companion, although the accounts do not entirely agree on his identity and there is no clear evidence that he was trained to pilot that device. The known sequence of May 25, 2003 is brief, but enough to explain why the case caught on so quickly. That afternoon, N844AA began taxiing without proper communication, entered the track without authorization and took off towards the southwest, towards the Atlantic and the Gulf of Guinea. Its lights were off and the transponder, the equipment that allows an aircraft to be identified in air traffic systems, was not transmitting. And there was another important point: the 500-gallon tanks installed in the cabin were part of the diesel transportation project, but they were not used to fuel the plane’s engines. To fly, the 727 relied solely on the aircraft fuel available in its own tanks. If he went low, he would hardly have gone far; If there was more margin, the range of possibilities expanded. Delta Air Lines retired its last 727 from scheduled service in April 2003. The image shows a plane of that model, not the N844AA missing in Angola The search did not close the case either. US organizations such as the FBI, the CIA, the State Department, Homeland Security and CENTCOM participated in it, and the US embassies in Africa received notices to monitor a plane that needed a long runway to land. In the weeks that followed, and also over the years, theories circulated: a fall into the sear, a landing at another airfield, a dismantling to sell components or even its use on irregular routes. A runway of a repainted 727 in Conakry, Guinea, looked promising in July 2003but the US authorities ended up discarding it. A possible terrorist connection was also examined, in the midst of post-9/11 sensitivity. It was a logical fear for Western intelligence services at the time, but The Washington Post and ABC News agree that no evidence emerged to support that hypothesis. That is precisely what keeps the enigma alive 23 years later. There is no confirmed landingidentified remains, pieces publicly linked to N844AA nor a record of maintenance or sales of components that would allow its fate to be reconstructed. If one day an answer appears, it will probably not be the entire plane: it will be a fragment, a document or a part number capable of finally giving it a place on the map.

There is only one person in Star Trek history who has played herself, and the scene remains legendary

by

The android Data needed the three most brilliant scientists in history for a game of poker on the holodeck, and the chosen ones were Isaac Newton, Albert Einstein and Stephen Hawking. The first two had been dead for decades (or centuries). The third was fifty-one years old and had amyotrophic lateral sclerosis, but he had expressed his desire to appear in the series to Paramount bosses. When was it? On June 21, 1993, the finale of the sixth season of ‘Star Trek: The Next Generation’. The first ninety seconds of the episode, titled ‘Descent, Part 1’, contain something that It hasn’t happened again. in more than fifty years of franchise: a real person, with a first and last name, playing himself. It was Stephen Hawking. How it started. Hawking visited the offices of Paramount Pictures in 1991 to present a documentary about his life directed by Errol Morris. Rick Berman, executive producer of the series, discovered during the visit that Hawking was a trekkie declared and offered him a tour of the sets of ‘The New Generation’. And once on the set, the scientist made an unusual request: that he be taken out of his wheelchair (something unusual) so he could sit in the captain’s chair. Once installed, he commented to his host Leonard Nimoy (Spock in the original series) that the seat was considerably more comfortable and powerful than his chair. He then asked if there was any chance of appearing on the show. The producers took note. Hawking would return to Los Angeles a few months later, and a filming window was available. All that was left was to know what the hell a theoretical physicist with ALS was going to do in an episode of a science fiction series without it coming off as parody, or even condescending. To do. The scriptwriters decided that the most appropriate thing was a scene in the holodeck, probably accompanied by the android Data. From there, it was time to build a scene that justified the presence of the most famous scientist in the world. Executive producer Michael Piller came up with the idea that solved it all: a poker game. The Enterprise holodeck allowed any historical figure to be recreated with precision, and the lucky ones were Newton, dead since 1727, and Einstein, since 1955. And Hawking, also dead in the fiction of the series, but capable of playing himself. To construct the physics joke that opens the scene, screenwriter Ronald D. Moore called his partner Naren Shankar, a doctor in applied physics and future showrunner of ‘CSI’. Shankar designed the Mercury perihelion joke (a phenomenon that Newtonian mechanics is unable to explain), and proposed the comic dynamic between the three scientists, with Hawking and Einstein mocking Newton. April 8. Hawking filmed his appearance April 8, 1993. Brent Spiner, who played Data and usually had no problem bringing the android’s emotional coldness to life, was nervous. The actor later described that moment as “probably my favorite moment in my entire experience doing Star Trek.” The scene that was filmed that day ended up lasting less than two minutes. In it, after joking about the possible apocryphal quality of the story of Newton and the apple, Hawking wins the hand, and Einstein argues that the odds of that victory could not have been improved even by quantum fluctuations. Hawking replies (with seconds): “Wrong again, Albert.” A historic cameo. It was not the first time that ‘Star Trek’ played with historical figures: we had even seen Abraham Lincoln fighting alongside Kirk and Spock. But Hawking is still, todaythe only real person to have played herself in any series or film in the ‘Star Trek’ universe. Furthermore, that cameo came at a particular time for the franchise: the audience for the sixth season of ‘The Next Generation’ was beginning to experience a gradual decline and ‘Deep Space Nine’ premiered that year. The franchise was expanding and the public was divided, but there was time for a cameo that was almost a declaration of intent. Moore claims that Hawking had helped build, with his work on black holes and cosmology, the type of scientific imaginary that ‘Star Trek’ had been playing with for decades. That he wanted to appear on the show, that he didn’t disdain science fiction but rather enjoyed it, functioned as a kind of circular validation. That’s why there is one last icing on the cake in the chapter: in the future that the episode imagines, it is revealed that Data holds the Lucasian Chair of Mathematics at the University of Cambridge. That same chair was held by Hawking between 1979 and 2009, and before him, Newton between 1669 and 1702. The three would end up sitting at a poker table in a future imagined in 1993.

Threads already boasts 500 million users. The missing figure remains the most important

by

Threads was born at the time when competing with X seemed more possible than ever. The old Twitter was going through a period of profound changes under Elon Musk and Meta decided to enter with its own app in a field that X had dominated for years: brief, immediate public conversation supported by text. What was not clear was whether that window could become sustained use, community and real scale. Almost three years after its launch, the company already has an answer to teach the market. The data comes from the Goal itself, which has announced that Threads It has reached 500 million monthly active users in June 2026. The application would have added about 100 million monthly users since August of last year, when it was already around 400 million. It is a huge figure for such a young network and enough to place it in a very different conversation than in its first months. The company led by Mark Zuckerberg has presented the milestone along with several new features, with special emphasis on reinforcing the role of communities within Threads. In its official announcement, Meta maintains that these groups, organized around conversations on topics such as books, basketball, parenting or musichave helped shape the application. That’s why Communities It is now out of beta and adds functions such as a center to find communities, own icons, progress indicators for topics that are close to becoming a community and more recognition for outstanding users. The figures we have and the figures we are missing Part of the explanation is that Threads didn’t have to convince the user to start from a blank page. It’s no secret that upon its initial launch it benefited from a highly optimized growth strategy: the app was able to build on the connections that millions of people already had on Instagram, and some viral Threads posts even appeared on Instagram and Facebook. This advantage helps to understand why its adoption was so rapid, although it does not solve the underlying question: how many of those users have turned Threads into a commonly used app. This pace places Threads in a striking position if we compare it with other large networks, although with an important caution: not all of them were born in the same conditions nor did they communicate their metrics in the same way. TikTok/Douyin reached 500 million monthly active users in July 2018a little less than two years later of the launch of Douyin in China. Instagram reached that barrier in June 2016some five years and eight months after its premiere. Facebook announced 500 million active users in July 2010a little more than six years after its birth, although that communication did not formulate the metric with the same detail as MAU. Threads did it just before turning three years old. There is the missing figure. Meta has given the global number, but has not published the breakdown by country: we do not know what Threads’ main market is, where the growth is concentrated or how many monthly active users it has in Spain. That gap matters because a social network is not only measured by its aggregate size, but by the weight it achieves in each local conversation. And in Spain, without a public figure that allows it to be measured, Threads does not yet seem to occupy a place comparable to that of X, Instagram or TikTok. Some clues help to read this incomplete map, although none replace the official breakdown that we do not have. In its announcement, the company led by Mark Zuckerberg mentions that local communities will start with native language labels in Japan, Korea and Taiwana clue as to where you are putting the focus. Meta claims to be seeing more traction in Asia, especially in South Korea and Japan, where usage time has increased by 80% and 130%, respectively, compared to the previous year. This is useful data, but it is not equivalent to knowing how many monthly active users there are in each country.

Today on Netflix the series that, nine years after its premiere, remains the best thriller ever seen on streaming

by

How many times, watching a series, do you have that curious feeling of “I’m watching the history of the medium”? You may have noticed it with series that not only impact you in a special way, but you also know that the people around you who also watch it experience a very similar feeling. If you’re watching ‘Succession‘You’ll know what I’m talking about. My last time, before HBO’s magnificent family intrigue epic, was on ‘Mindhunter‘, that Netflix premiered in 2017. Nine years later, it is still my favorite series of all those released on the platform. Neither ‘Stranger Things‘, neither ‘The Witcher‘, neither ‘sandman‘ nor any other have managed to match the degree of intensity and perversity of this brief masterpiece by Joe Penhall (also screenwriter of ‘The Road’) in which David Fincher directed some chapters. It started from a real event in the history of criminology: in 1977, two FBI agents revolutionized investigation techniques, giving a twist to how to get into the minds of serial killers. The series is based on the book written by some of the protagonists, and although obviously the suspense and suspicions generated by the agents’ investigation are played here, as well as the portrait of famous murderers such as the Son of Sam, Ed Kemper, Charles Manson or BTK, the realistic reflection of an era is above all. A realism that takes great care to present heroes and villains, and much less to mythologize serial killers, as the worst do. true crimes. ‘Mindhunter’ describes with coldness and a certain perverse sense of humor (and here the Fincher style is clearly evident) these first times in which psychology entered in the darkest minds and abysmal, with a fascinating portrait of these first methodologies. And all supported by an excellent cast (Jonathan Groff, Holt McCallany and Anna Torv) that not only gives credibility to the ensemble, but also catapults the empathy we experience for a group of researchers who, literally, tread on absolutely unknown ground.

The animal testing of the elixir for future warfare has been a success. Now the most difficult thing remains: making it work in humans

by

In 1667, the French doctor Jean-Baptiste Denis performed one of the first transfusions of history using lamb’s blood on a human patient, convinced that it could calm his behavior and save his life. The experiment generated such controversy that ended up being banned in several countries for decades, leaving a lesson that has accompanied medicine since then: when it comes to replacing blood, each advance opens a door… and also a risk that is difficult to foresee. An experiment that redefines war medicine. A lot has happened since that test by Denis, but now it is making strong noises again with the development of a powdered blood substituteone that marks one of the most ambitious advances in military preparation for future conflicts, where conditions no longer guarantee rapid evacuations or immediate access to hospitals. In this context, the idea of ​​transforming blood into a portable and stable resource ceases to be science fiction and becomes a solution, or perhaps an operational necessity. They counted on Insider that, for the Pentagon, what is at stake is not only improving logistics, but changing the way soldiers’ lives are saved in environments where every minute counts and medical infrastructure may not exist. The “elixir” that seeks to change war. The program powered by DARPA has managed to turn a complex concept into a potentially revolutionary solution: a powdered blood substitute that can be stored, transported and activated in a matter of seconds. This system is presented as an alternative to the current model, where fresh blood is limited, perishable and difficult to move in combat zones. The key, they say, is in its operational simplicity: mix the contents with sterile water and have a vital resource at the exact moment it is needed. Success in the laboratory. The initial results have been promising enough to generate expectations within the military and scientific field. After demonstrating its viability in controlled environments and later in animal models, the project has overcome one of the most complex phases of biomedical development. In other words, the advance suggests that the concept works in biological termsopening the door to real applications in scenarios where conventional transfusions are not possible. The great challenge. There is no doubt, despite of the advancesthe final jump remains the most difficult of all. The next step is to overcome the regulatory processes and demonstrate that the system is safe and effective in humansa long path that involves clinical trials, medical validation and approval from regulatory bodies. In fact, this is where many promising developments stall, not because of a lack of technology, but because of the complexity of ensuring that they work in real conditions without unexpected risks. A necessity. They counted in their report in Insider that interest in this type of solutions does not arise in a vacuum, but as a response to a profound change in the nature of conflicts. Conflicts have shown that air superiority no longer guarantees rapid evacuations, and the wounded can be trapped for hours without access to advanced medical care. In these contexts, the immediate availability of blood becomes a critical factor that can make the difference between life and death. Limitations of the current system. In the absence of alternatives, the armed forces have resorted to methods such as emergency transfusions among soldiers, known as “living blood banks.” Although effective in specific situations, these solutions depend on the availability of donors and cannot scale in scenarios with multiple casualties. Again, this highlights the need for a more robust solution, capable of responding to high-intensity situations without relying on improvised resources. Beyond science. The future of this technology announced by DARPA depends not only on its medical effectiveness, but also on its economic viability. The production, distribution and adoption of synthetic blood require significant investments in a sector where margins are traditionally low. Without a sustainable model that incentivizes companies and hospitals, even the most promising advances can remain in the experimental phase, never reaching the battlefield. Be that as it may, the objective set is more than ambitious: to turn development into an operational tool before end of the decade. To achieve this, almost nothing: coordinate science, regulation and industry in an accelerated process that avoids the usual blockages in such complex projects. But if successful, this sort of modern “elixir” could redefine war medicine, bringing the ability to save lives directly to where it is needed most.

The US remains committed to stopping China. Now it has targeted the second largest Chinese chip manufacturer

by

SMIC (Semiconductor Manufacturing International Corp) is the largest Chinese semiconductor manufacturer with a global market share 5.32%. Only TSMC and Samsung surpass it. Currently this is the only Chinese company that has the necessary technology to manufacture 7nm integrated circuitsbut Hua Hong Semiconductor, China’s second largest chip producer, is developing the technology necessary to manufacture this class of semiconductors. The US Department of Commerce has confirmed without intending it that Hua Hong Semiconductor is very serious with its 7nm photolithography. And it has done so because, according to Reutershas notified the most important lithography and wafer processing equipment manufacturers in the US that they no longer have permission to deliver their most advanced machines to this Chinese company. The purpose of this US entity is clear: it aims to make it difficult for Hua Hong Semiconductor to conclude the development of its 7nm lithography. Lam Research, Applied Materials and KLA already have one more obstacle in China Department of Commerce technicians analyze export requests within the framework established by current regulations and approve or deny the sale of integrated circuits and wafer processing equipment to China. The current regulation is the most effective tool at the disposal of the US Government to try to slow down the development of China’s semiconductor industry and prevent it from acquiring the capacity to manufacture cutting-edge integrated circuits in the short or medium term. Hua Hong is preparing to start production of 7nm chips at its Shanghai plant Hua Hong Semiconductor’s division specializing in third-party chip manufacturing is called Huali Microelectronics, and it is preparing to launch the production of 7nm integrated circuits at its Shanghai plant. The sources that have revealed this information assure that Huawei has collaborated with Huali Microelectronics on this project, which invites us to reach two reasonable conclusions. The first is that Huali’s 7nm lithography is likely to play an essential role in GPU production capacity for artificial intelligence (AI) from both Huawei and other Chinese companies. And the second conclusion is actually a plausible hypothesis. And, like SMIC, Huali does not have access to ASML SVU teams. For this reason, it is very likely that with the help of Huawei it has developed security techniques. multiple patterning to be able to manufacture 7nm chips with the UVP machines in its possession. Lam Research, Applied Materials and KLA are three of the US companies that the Commerce Department has notified that they can no longer provide Hua Hong Semiconductor with their most advanced wafer processing equipment. China is a very important market for these companies, so presumably they are going to lose several billions of dollars in sales. Lin Jian, the spokesperson for the Chinese Ministry of Foreign Affairs, has declared that his country expects the United States to stabilize global industrial and supply chains and keep trade functioning normally.

the remains of a 17th century nobleman that have not decomposed over the years

by

In the crypt of a small rural church in Kampehl, a town in Brandenburg, one of the most studied and controversial corpses on the entire continent has been lying for more than three centuries: that of Christian Friedrich von Kahlbutz, a feudal lord of the town who died in 1702. What is so special about a nobleman? German Prussian died more than 300 years ago? That at this point he should be decomposed and not only is he not, but his body is preserved in an exceptional way, that is, mummified naturally, without anyone embalming it. The discovery. It was the year 1794 when, while the Kampehl church was being renovated, workers opened the family crypt with the intention of moving the remains and demolishing the vault. Over there they found three coffins: two contained completely decomposed corpses and in the third was the body of Christian Friedrich von Kahlbutz, quite intact, dry and with an appearance reminiscent of leather. The nobleman was a mummy that preserved recognizable facial remains, remains of hair and part of the clothing they used to bury him (another thing is that with the passage of time and desecrations he remained naked, which earned him that nickname). Since the coffin had no name, the initials on the shroud served to identify him. The Kalebuz knight is extremely well preserved for his age. Via: Anagoria The character. If the state of preservation of Christian Friedrich von Kahlbutz is already striking, his life (and the legends that have emerged around it) are not far behind. The knight Kalebuz (that is the correct spelling according to the parish book of the Köritz church) was not actually a knight by military rank (he was a cornet) but by belonging to the nobility, he participated in the Battle of Fehrbellin and he won but not before injuring his left knee, as they say. Stay with this last piece of information. As a reward, they granted him the lordship of Kampehl. There he married and had numerous legitimate children and many others illegitimate. Among other things, because among its practices was the right of stay. In 1690, a servant named Maria Leppin accused him of the murder of her fiancé, Pastor Pickert, supposedly because the young woman had denied him the right to stay. One of the (many) good things about his status was that swearing that he had not been was enough for acquittal. And so he did in the court of Dreetz. The legend tells that in that oath he said something like: “If I am the murderer, may God ensure that my corpse never rots.” Since the original trial records no longer exist, there is no way to verify it. The hypotheses of its natural embalming. Leaving aside the explanation of the divine promise for obvious reasons, several explanations for the mummification of the Kalebuz knight have been proposed over the years: Mummification by healing (yes, like sausage) is the main one: the coffin used was of exceptional quality, made of double oak and raised on four legs, which allowed dry air currents to extract moisture from the body before bacterial decomposition. This was helped by a well-ventilated crypt, the sealing of the coffin to prevent access by ghoul insects, and the condition of the corpse itself. Apparently Kahlbutz probably suffered a serious lung disease (such as tuberculosis) and was already very deteriorated, with little nutritional substrate for microorganisms. This is what is deduced from comprehensive analysis report of the team Professor Andreas Winkelmannprofessor of anatomy at the Brandenburg Medical School Theodor Fontane. The effect of ingesting toxic substances. Another hypothesis that is more difficult to verify point to the chronic ingestion of toxic substances common in the pharmacy of the time (such as arsenic or mercury) that could have impregnated the tissues with compounds that inhibited decomposition, in addition to, of course, slowly poisoning him. After three centuries, these substances transform or volatilize and leave little analytical trace. Soil conditions. In addition, there is research that suggest that the sandy and dry composition of the crypt subsoil could have been a contributing factor in the extraction of moisture. Mummification by healing, the main hypothesis. Anagoria Yes, but. The passage of time, looters and legends do not make it easy to shed some light and science on the mystery of the good preservation of the Kalebuz knight. The fact that the trial records do not exist is in fact the least of the problems. The thorniest thing is identity: trusting everything to the initials of the shroud is a delicate matter. In 1983 a computed tomography made by Professor Meinhard Lüning at the Charité Hospital in Berlin found no trace of the knee injury. Neither does the 2024 investigation. Furthermore, Knight Kalebuz had two sons with the same initials, although it is not recorded that they died in Kampehl. In 2024 they also did a DNA analysis and there they could neither confirm nor deny that tuberculosis was the cause of death. In short: it is not known what ended the life of this nobleman. The most disconcerting thing is that the CT scan showed a pencil in the middle of the chest cavity. The only explanation is a subsequent manipulation: in 1895 the doctor Rudolf Virchow performed an extraction of tissue leaving a hole in the chest, which made it possible for someone to insert the object. The pencil was identified as Faber brand and dated between 1900 and 1920, which fits with the period in which the mummy was already on display to the public.
