clarified

your CEO just clarified who should have the best

by

The race for artificial intelligence is usually told through models, applications and the latest promises of automation. But beneath all that there is a less attractive layer and much more difficult to replace: the hardware. Without advanced chips, training massive models, deploying them at scale, and competing on the front lines becomes much more difficult. That is why NVIDIA continues to occupy such an important place for the United States and China. The question is no longer just who develops AI better, but who can access the most powerful chips first. Huang’s message. That debate landed this week in Los Angeles, during the Milken Institute Global Conferencea forum that brought together bankers, investors, policymakers and executives in Beverly Hills. Over there, according to Nikkei AsiaJensen Huang was asked directly about a particularly sensitive question: whether China should have access to NVIDIA’s “latest and greatest” chips. His response was as brief as it was forceful: “No.” The CEO later added that the company supports the United States having “the first, most and best” chips, a phrase that pretty much sums up the balance it is trying to defend. Sell ​​yes, but not the last. Huang’s position is not about removing China from the trade equation, at least not according to what he proposed in that same forum. The CEO defended that American semiconductor companies continue to compete in global markets, including China, because that also strengthens the North American country. Huang said that increasing exports helps raise tax revenue, improve economic security and contribute to national security. The message, therefore, has two layers: technological leadership first, and commercial presence under control later. The border is in the generation. Not all NVIDIA chips occupy the same place in this discussion. The H200, remember, is a high-end AI processor and places it above of the H20the chip the company designed for China after US export restrictions. But the agreement announced by Donald Trump in December did not include neither Blackwell nor the next-generation Rubin products, two families that represent a more advanced layer of NVIDIA’s roadmap. The regulatory framework still has several moving parts. Donald Trump said in December that he would allow NVIDIA’s H200s to be sold to “approved” customers in China, as long as the US Government received 25% of those income. The company obtained official export authorization this year, and Huang said in March that NVIDIA had already received orders from “many Chinese customers.” But that does not mean that everything is resolved: the final shipment will also depend on whether Beijing allows such sales and in what quantities. The bottleneck is not just political.Tom’s Hardware suggests that there may also be an industrial explanation behind the absence of recent shipments. According to the media, Hopper and Blackwell are manufactured in the same factories and production lines compatible with TSMC’s N4/N5, a capacity that is not infinite. If that reading is correct, NVIDIA would have reason to reserve more production for Blackwell, a more advanced and expensive family, especially for US customers, instead of using part of that capacity in H200 for China with a 25% commission to the US Government. According to that reading, Rubin’s arrival at N3 could free up margin later. A pending trip. Trump said he will visit Beijing this month and that trade issues could be on the table in his meeting with Xi Jinping. In that context, Huang’s words do not sound like a simple corporate reflection, but rather a way of marking a position in a debate that goes far beyond NVIDIA. The dispute not only revolves around which chip is more powerful, but also about who accesses it first, under what conditions and with what margin so as not to be left behind.

Drink water right before going to sleep? Science has finally clarified whether it is a good idea or a terrible enemy of sleep

by

Before going to sleep, some people may have an almost standardized ritual in which they should drink one or two glasses of water, and also have a backup on the bedside table in case they get thirsty in the middle of the night. But there are also many questions about whether it is positive to drink water before sleeping for eight hours or if it is counterproductive by forcing us to get up in the middle of the night. And here science has something to say. It has benefits. What is clearly known is that during the night our body does not go into a total pause, but rather continues with an active metabolism even though it is attenuated. That is why we lose approximately half a liter of water simply due to evaporation when breathing and sweating, and to compensate for this, hydration can be the best ally. It is investigated. A Japanese studio published this same year analyzed a group of middle-aged men to conclude that drinking 280 ml of water just before going to bed significantly reduces morning depressive mood and improves well-being upon waking up. But it is not the only one, because a 2025 crossover trial with 15 healthy adults found a relationship between drinking fluids before sleeping and the duration and quality of sleep. REM phasewhich is what makes us truly rest. And it makes sense, because adequate hydration favors the release of vasopressin, a key hormone for regulating the biological clock and preventing tissue dehydration during deep sleep. And it is essential, because it can translate into less fatigue and headaches in the morning. He has problems. It will not always be beneficial to have this habit, since the main enemy of drinking water at night is nocturiawhich is the need to wake up to urinate during the night. And although the total time we spend awake is not drastically altered, because it is only a few minutes, there is an interruption in sleep. It depends on the quantity. Logically, drinking a glass of water is not the same as drinking a whole bottle before going to sleep. That is why when you go over half a liter of water there is a possibility that some pre-existing problems such as chronic insomnia will worsen or even increase the risk of falls when getting up in the dark. How to do it. There are a series of tips that we can follow to stay hydrated during sleep and they are summarized in the following points: You should limit yourself to drinking around a quarter of a liter of water in the final part of the day to avoid overfilling your bladder. The last glass of water should be drunk two hours before going to sleep. Maintain good hydration throughout the day to avoid reaching the end of the day with a major hydration problem.

the Webb telescope has just clarified a key doubt

by

There are asteroids that go almost unnoticed and others that force us to look at them much more carefully. 2024 YR4 belongs to that second group. When it was discovered at the end of 2024, the first calculations of its trajectory still had enough margin of error to contemplate a very small possibility of impact with Earth. That scenario was soon ruled out, but, as ESA explainsthe case remained under follow-up for a different reason: a doubt was left open about the Moon which was not resolved until new observations arrived. Impact risk. With data available since spring 2025, trajectory models indicated that the asteroid had about a 4% chance of hitting the Moon on December 22, 2032, an estimate that NASA placed at 4.3% in its previous calculations. It was not a high percentage, but it was significant enough for the teams dedicated to monitoring near-Earth objects to follow it with special attention. Furthermore, we are talking about an object of about 60 meters. How Webb came into play. To clear up that doubt, something more than the usual telescopes was needed. An international team of astronomers identified two very specific windows in February 2026 in which the James Webb Space Telescope could try to detect the asteroid, which at that time was just an extremely faint point millions of kilometers away. It involved using one of the most complex scientific instruments built to date to locate an almost invisible object and measure its position with the necessary precision to project its orbit almost seven years into the future. Key piece. The observations were made on February 18 and 26, 2026 with the camera NIRCam of the James Webb telescope. From these images, astronomers compared the position of the asteroid with that of the background stars, whose coordinates are known with great precision thanks to ESA’s Gaia mission. ESA adds a relevant detail to understand why this went ahead: the planning and analysis was coordinated with ESA’s Near-Earth Object Coordination Center, NASA’s Center for Near-Earth Object Studies and the Webb mission team. With this new data package, the orbital models were adjusted enough to close the mystery. James Webb analyzed the position of the asteroid in relation to the background stars The flyby distance. With the new calculations, monitoring teams can now estimate quite accurately what the asteroid’s passage through the lunar environment will be like. According to NASA, it will pass on December 22, 2032 about 21,000 kilometers from the surface of the Moon. That range is enough to eliminate the impact scenario that had been on the table for months. In other words, the object will continue on its way through the solar system without hitting either the Moon or Earth. Surveillance doesn’t stop. Programs such as ESA’s Space Security or NASA’s tracking systems continue to detect and analyze near-Earth objects to anticipate any possible future threats. The logic is simple: the sooner a potentially dangerous object is identified, the more room there will be to study its trajectory and assess the real risk. In this case, the result has been reassuring, but it also illustrates, as ESA insists, what planetary defense means in practice when a doubt is resolved with more data and better measurements.
