We thought Stanford, MIT, and Harvard were leading in AI. There is a Chinese university that surpasses them all

November 25, 2025 by usatoday24

To the northwest of Beijing there is a university campus that is not only the most prestigious in the country, it is also one of the most influential universities in the world in science and technology, even surpassing institutions of the stature of MIT or Stanford. It is called Tsinghua and some of the most important technological projects of the moment are being developed there. Change of focus. Tsinghua has been in operation since 1911, although it was not until 1952 when it became a polytechnic university. Among its former students there are figures of the stature of Nobel Prize in Physics Chen-Ning Yang and President Xi Jinping himself. From its inception, Tsinghua’s focus was the training of Chinese students who were going to continue their studies in the United States. Today that approach has completely changed. In the midst of an AI career, there is a nationalistic spirit and students tend to stay and develop projects in their native country. Leaders. They count in Bloomberg that Tsinghua University stands toe-to-toe with the best universities in the world. According to the US News rankingis the best university in the world in engineering, chemical engineering and electronic engineering; has second place in civil engineering and nanotechnology; It is third in materials science and fourth in computer science. There it is nothing. Intellectual property. Tsinghua is also the university with the most papers on AI among the 100 most cited and leads in patent registration, outnumbering MIT, Stanford, Princeton, and Harvard combined. According to LexisNexis data analyzed by Bloomberghave registered 4,986 patents on AI and machine learning in the last 20 years. In 2024 alone they registered 900 patents. However, according to the Stanford AI Indexthe most influential patents remain in American hands. Startups. The university not only focuses on training, it also has a startup incubator called X-Lab from which at least 900 startups have already emerged since it was created in 2013. They are currently very focused on projects related to artificial intelligence. The founders of startups such as Moonshot AIthe creators of the model Kimi K2either Sapient Inca startup that develops “hierarchical reasoning models” based on how the human brain works. They affirm that it is the way to achieve AGI, a different approach to that pursued by companies like OpenAI with LLM or WLM (world models). that LeCun recently defended. Chip war. Efforts are also being made in Tsinghua to give China a boost in the technological war with the United States. The clearest example is the chip created by a group of university scientists and it is 3.7 faster than NVIDIA’s A100. Not only that, the chip, called ACCEL, is also much more efficient. At the moment its mass production has not been achieved, but the innovation is there.

Someone at Harvard suggested that 3I/ATLAS was an alien ship. A new test has revealed to us what it really is

November 12, 2025 by usatoday24

Without a doubt one of the space objects that has been causing the most sensation in recent months is 3I/ATLAS. Practically everything has been said in recent months, from the fact that it is a simple asteroid that was going to destroy our planet to the fact that it was an alien shipas noted a professor from the prestigious Harvard. But all these ideas have been left in nothing thanks to the last signal that has been interpreted from this object. What he imagined. Interstellar object 3I/ATLAS, the third such visitor ever detected, has kept the scientific community (and science fiction fans) in suspense since its discovery in July. The most “far-fetched” speculations, as experts have described them, went so far as to suggest that it could be an extraterrestrial spacecraft, especially when it temporarily disappeared behind the Sun. The sign that explains everything. On October 24, the radio telescope MeerKAT In South Africa, a powerful network of 64 antennas captured the key evidence. This was neither an encrypted message nor a technological transmission from another species, but rather an absorption radio signal caused by hydroxyl molecules. What does it mean. Hydroxyl molecules are the direct result of the ‘breaking’ of a water molecule. This is something that happens when the ice in the nucleus of a comet approaches the Sun and sublimates due to the large amount of energy it absorbs. That is, it automatically goes from solid to gas and this is what we have detected from Earth, as has explained Michael Küppers, scientist at the European Space Agency (ESA). In summary, we are talking about 3I/ATLAS containing ice inside, as happens in comets (and not in extraterrestrial spacecraft). And we are completely sure of this, since these absorption signals are like the molecular DNI, it is unique for each compound. Goodbye speculation. As we have mentioned before, the alien ship theory gained traction when the object hid behind the Sun. Some speculated that it was maneuvering or hiding from our radars. However, on November 4, 3I/ATLAS reappeared exactly where orbital calculations predicted it would be. There were no maneuvers, just physics. Furthermore, it is not the first time it has been detected. Javier Peralta, an expert in planetary atmospheres, recalls that NASA’s Swift space telescope had already observed hydroxyl in the ultraviolet spectrum. MeerKAT’s new detection is crucial because it confirms the same composition in a completely different band of the electromagnetic spectrum: radio. What does the future hold for us? 3I/ATLAS is the third known interstellar visitor, after 1I/’Oumuamua in 2017 and 2I/Borisov in 2019. Although its trajectory is too long and it has traveled too long to know which star it comes from. But the important thing is that we are already preparing for what is coming. ESA’s JUICE mission, currently en route to Jupiter, will take new radio measurements from 3I/ATLAS in February 2026. But the big bet is the mission ESA Comet Interceptorwhich will be launched around 2029 and will wait for the next large comet to approach our planet.

A Harvard astronomer has accused NASA of hiding 3I/ATLAS images. has an explanation

November 1, 2025 by usatoday24

Avi Loeb, the controversial cosmologist of Harvard University, has accused NASA of withholding important data on the interstellar comet 3I/ATLAS, and is mobilizing the US Congress to demand its release. But this alleged concealment of evidence is not what it seems. Weeks without seeing the photos. In one post on your blogLoeb denounces that NASA has not made public images of the object taken with the HiRISE camera of the Mars Reconnaissance Orbiter probe from Mars orbit for weeks. These images, captured between October 2 and 3, when 3I/ATLAS passed within 30 million kilometers of the red planet, are, according to Loeb, “extremely valuable” scientific data. The reason is that they would have a resolution of 30 kilometers per pixel, three times greater than the best available image of the interstellar object, taken by the Hubble Space Telescope. This “side perspective” could be important for understanding the object’s geometry and its brightness, so Loeb asked US Congresswoman Paulina Luna to demand that NASA’s acting administrator, Sean Duffy, release it. The explanation. NASA has justified the lack of images with a very earthly argument: the delays caused by the closure of the United States government since October 1. NASA is officially on “shutdown” and with 83% of its staff on unpaid leave due to the lack of agreement in Congress on the 2026 federal budgets. Only the International Space Station control room and the operators in charge of ship and satellite security, as well as a handful of critical jobs, continue to function. The rest (a large part of science, dissemination, aid processing, etc.) is on pause. Why so much interest in 3I/ATLAS. Comet 3I/ATLAS is the third interstellar object detected in our solar system. Since its discovery, it has shown behavior somewhat disconcerting which has led Avi Loeb to defend the hypothesis that it could be an artificial extraterrestrial object. The latest anomaly occurred near its perihelion (the closest point in its orbit to the Sun) on October 29, when 3I/ATLAS shone brightly in blue and experienced an acceleration which cannot be explained by the gravity of the Sun. Most likely? That the comet was degassing as it warmed up, and the sublimated ice acted as propellants. If you don’t pay attention to it you get bored. Loeb has calculated the possibility that 3I/ATLAS is a natural object: “less than one part in ten quadrillion”. The astronomer highlights the trajectory almost perfectly aligned with the plane of the planets, an unusually large mass, a very low proportion of water (only 4%) and a surprising abundance of nickel as evidence. But this is not the first time that Loeb has proposed that an interstellar object is a technological and “possibly hostile” object. In fact, it’s the second time he’s done it (the first with ‘Oumuamua), and we only know of three interstellar objects that have visited our solar system. The scientific community does not play along. Compared to Loeb’s hypotheses, the vast majority of astronomers offer much more mundane explanations. The blue glow is consistent with emissions of ionized gas from other active comets. Other physical characteristics could be explained if 3I/ATLAS were the ejection of a piece of exoplanet by a natural collision far from Earth. As for the news that “NASA” activated its defense protocol against 3I/ATLAS, it also has a simple explanation: the International Asteroid Warning Network has chosen measure the position of the interstellar comet for an observation campaign that had been planned since 2024, not with the aim of defending ourselves from. an alien attack, but to improve astrometry systems.

Harvard bought a cheap copy of the Magna Carta in 1946. They just discovered that they had a treasure that is worth a fortune

May 16, 2025 by usatoday24

Year 1946. Someone buys a cheap and no apparent copy of The Magna Carta After ending World War II. The article, dated in 1327, passes without penalty or glory for decades in some trunk of the Harvard Law School. Today, eighty years later, to the surprise of the entire world it has been discovered that it was actually one of The original writings. A medieval jewel. In other words: for eight decades, a very valuable original of the 1300 Magna Cart bad of 1327. acquired at the time for just $ 27.50 In 46, the document was bought from a London bookseller and, since then, lay in oblivion. It was not until December 2023 when David Carpenter, professor of medieval history at the King’s College in London, He identified it while sailing through the Harvard digital library. When observing the sheep skin scroll (labeled as HLS MS 172) it was dumbfounded: design, calligraphy, Latin use and the capital “E” characteristic of Edwardus coincided with The original specimens known He immediately alerted his colleague Nicholas Vincent, a professor at the University of East Anglia, who confirmed authenticity of the finding. With the discovery, they ascend to 24 The original specimens Known of the edition, the last officially issued by the Royal Foreign Ministry during the reign of Eduardo I. A 725 -year -old relic. The document, in remarkable state of conservation, was produced in the year 28 of the reign of Eduardo I and represents the culmination of a series of reference to the Carta Magna since their original conception in 1215, when the English barons, in open rebellion, forced the king to accept that even the monarchy had to submit to the law. The text was reissued several times for its successors and ended up consolidating as one of the pillars of the Western constitutional thinking. The authenticity of the Harvard specimen already It has been validated with spectral and ultraviolet image techniques (image below), which allowed to compare the text and paleographic marks with other authentic specimens. In contrast to the deteriorated document found in 2014 In Sandwich, England (which was incomplete, without seal and partially illegible), Harvard’s piece retains its integrity and clarity. The thoroughly examined letter Historical Genealogy. Harvard experts tell that the documentary trail suggests that the copy could be the Magna Carta originally sent to the municipality of Appleby-in-Westmorland, in northern England. It is presumed that it was delivered by Lord Lord William Lowther to the abolitionist Thomas Clarkson, one of the most influential figures in the eradication of British slave trafficking. Clarkson, author of The History of the Abolition of the African Slave-Tradehe retired to the area, and his family archive was subsequently inherited by the aviator and war hero Forster Maynard. In fact, it was he who He auctioned in 1945 Through Sotheby’s, where Harvard acquired it without noticing his true importance. Although there is still a conclusive evidence that confirms such documentary genealogy, the chain of custody is more than solid and plausible. Symbol I live in times of tension. The American media counted this morning that the rediscovery of the document also arrives at one time politically loaded: Harvard University faces direct pressures from the Trump government, which recently announced the Cancellation of 450 million dollars in federal financing after disputes over student protests related to war in Gaza and university autonomy. For Carpenterthe appearance of this founding letter in the midst of that conflict is not mere coincidence, but almost “providential”: a tangible reminder of the essential principle that power, even in its highest form, is subject to the law. “The Magna Carta says that the ruler cannot simply order your execution or appropriate your land: it must respect the law,” He pointed out. Constitutional inspiration. Finally, the relevance of the finding is not limited to its estimated historical value (there is talk of More than 20 million of dollars, considering that a 1297 version was sold in 2007 for 21.3 million), but also to its pedagogical and symbolic potential. In words From Amanda Watsonassociated dean of the Harvard Legal Library, the document offers a unique opportunity for future generations to understand the foundations of democracy, individual freedom and limited government. If you also want, that a medieval relic of this caliber emerges from the shelves of an American university In full struggle to preserve its academic autonomy against the impositions of state power, it gives an extra intangible to the finding, a weight that transcends the historical: a living lesson, written more than seven centuries ago, but more in force than ever.
