It’s a clue to your strategy for the hardware of the future

Apple has acquired Invrs.io, a small AI-guided photonics and optical research company. It is one of those purchases that almost goes unnoticed, but that reveals a lot about where Apple is aiming in the hardware and AI race. Below these lines we tell you all the details. What has happened. According to a notification published by the European Commission, Apple announced in October 2025 that it was acquiring certain assets of Invrs.io LLC and hiring its only employee and founder, Martin Schubert. The information was made public this week, after the regulatory waiting period of four months, according to counted MacRumors. Who is Schubert and what he did. Schubert founded Invrs.io in 2023 after spending more than a decade working on advanced display, chip and optics technologies at companies including Google, Alphabet, X and Meta. According to your LinkedIn profileaccumulates nearly a hundred patents. At Invrs.io his goal was to develop AI-guided design tools focused on optics and photonics, with direct applications in augmented and virtual reality, data centers and autonomous vehicles. The company, according to its page on GitHubbuilt open source frameworks for photonics research, with standardized simulations and a public ranking to compare design results. Why does this matter? Photonics is the science that studies how to generate, control and detect photons, that is, light particles. In practical terms, it is the basis for optical components such as cameras, sensors, displays, LiDAR scanners, and lenses for mixed reality devices. Apple has been integrating this type of technology into its products for years, from the iPhone’s camera system to the Apple Vision Pro. Bringing in someone specialized in designing those components with the help of AI allows you to speed up that process and do it with greater precision. The Apple pattern. This acquisition fits perfectly into Apple’s usual way of moving: small, silent purchases highly oriented toward specific capabilities, generally months before introducing a new product. In January of this year it bought Q.aian Israeli AI startup applied to audio, in what is considered its second largest historical acquisition with nearly $2 billion. Invrs.io is much more modest in size (it literally has one person in charge), but it gives us small clues as to how the company’s movements regarding its products will be in the following years. The hardware that accompanies AI. Although we are now witnessing a great technological battle to see who launches the most powerful AI model, there is a race in the background that will decide who stays on top, and that race involves hardware. Specifically, the hardware that AI will use to perceive the physical world: sensors, lenses, optical systems, computer vision technology, etc. Google now has Nano Bananaa model with which it works so that AI can generate images with knowledge of the real world. Apple, with moves like this, could bet on integrating ultra-precise optics into its wearables and future devices. They are different strategies, but with a common objective: to be the eyes of the AI. And now what. Apple has not confirmed which projects Schubert will work on internally, something completely common for the company. But everything indicates that the company will intend with this purchase to improve the optical components of future models of the Apple Vision Pro, the iPhone or devices yet to be announced.

A video of a Russian soldier ignoring a bomb falling on him is the clue to something deeper in Ukraine

This circulating a clip as brief as it is disturbing: what appears to be a fragmentation munition falls at a soldier’s feet, explodes practically beneath him and, against all logic, the man continues walking as if nothing had happened, “ignoring” the immediate impact of a detonation that, by pure physics, should have destroyed him or at least knocked him down and left him incapacitated. The explanation points to a tactic that is not new. What doesn’t fit. The most striking from the video It is not just that he remains standing, but the absence of the instinctive reaction that any body has to pain and shock, as if the nervous system were disconnected or anesthetized. And here comes the detail that makes the scene even more disturbing: according to Canadian analyst Roythe scene suggests that it is a Russian soldier, and that what we see is not a typical Ukrainian attack, but a deliberate attempt to eliminate him by his own people, perhaps because he was trying to defect. In that reading, the explosion would not be bad luck, but rather a covert execution, with what appears to be una OFSP-0.5, launched with the intention of cutting his retreat short and erasing any uncomfortable history before he crosses a line or surrenders. The “zombies” of Bakhmut. The image does not appear out of nowhere: it fits within a sensation that is repeated from the hardest moments of the siege at Bakhmutwhen Ukrainian fighters they described Russian attacks that seemed written by someone who doesn’t understand human survival. Waves of men advancing without coordination, without visible tactical logic, walking almost in a straight line towards enemy fire, with stories that spoke of soldiers who kept appearingalthough the first had already been killed, and with a strange passivity even under bombardment. We talk about videos where soldiers were seen move slowlystaggering, as if they were stuck in a thick dream, unable to move away even as grenades fell around them. In that framework, the video soldier current seems like the extreme version of the same impression. The drug hypothesis. For months, many Ukrainians have sustained an uncomfortable idea: that part of these attacks are not explained only by incompetence or desperation, but by soldiers “doped” envoyswith substances that reduce fear and disconnect prudence. The accusation appears in direct testimonies: men who seem euphoric or absent, who advance without understanding what they are doing, who do not retreat even if death is obvious, who react late or not at all. Not only that. Suspicion persists because, from a military point of view, the temptation it’s too clear: If what you need is infantry who will walk toward fire, who will endure a corridor battered by artillery, who will not be slowed by anxiety, and who will execute orders in an environment where instinct would say “flight,” a stimulant or narcotic mixture can make a soldier a more manageable asset. Pervitin, an early form of methamphetamine, which was widely used in Nazi Germany The Nazi shadow. To understand why this idea is not science fiction, just look at the most famous historical precedent: Nazi Germany led drug use combat at an industrial level with Pervitina low-dose amphetamine similar to modern methamphetamine that was first popularized in civilian society and then became a military multiplier. wanted something simple: reduce sleep, raise morale, reduce fear, increase aggression and sustain the execution of tasks without rest for days, just what is needed for rapid offensives and to maintain the rhythm when the body should collapse. And it wasn’t just the Nazis, also the allies. Super soldiers. That logic fit like a key in the blitzkrieg lock: continuous movements, mechanized attacks, advance without pause, a sensation of permanent thrust that overwhelmed the enemy not only because of the power, but because of the ability to not stop. He myth of the “super soldier” It wasn’t a futuristic helmet: it was a pill. And if that episode taught anything, it is that armies, when they believe they can gain an advantage or sustain performance, usually put immediate effectiveness before medium-term human cost. Soldiers under the influence. The pattern of effects attributed to this type of stimulant is perfectly compatible with what appears in many stories of the war: less fear, more aggressiveness, less need to sleep, more resistance to fatigue and a certain ease in executing simple commands even in extreme conditions. The price is usually the psychological and physical toll: dependency, depression, impulsivity, loss of judgment, and a progressive degradation of the soldier as a functional person outside of the moment of combat. On the front line, however, that bill is irrelevant to a short-term planner: if what you need is for someone to cross a field of fire today, you care little about what happens to them a month from now. That’s why video on networks It is so symbolic and striking: it seems to be the exact moment in which the body stops behaving like a human that preserves its life and begins to behave like a moving object that only obeys the forward vector. The other side of the coin. However, there is an essential nuance: “zombie” behavior does not always involve drugs. It may simply be the ugliest version from reality: extreme coldlack of equipment, exhaustion, hungeraccumulated sleep, sustained stress and the confusion of a mind that shuts down. The early hypothermiafor example, fits brutally with many clips: slowness, clumsiness, difficulty processing stimuli, confused speech, lost gaze. And in the Russian case there is also a historical tradition of war “fuel” much more mundane: alcohol as a tactical and psychological value, from vodka rations in World War II (used to combat the cold and to give courage before attacks) until modern episodes of indiscipline and documented drunkenness. A sign of the times. In short, the video that has gone viral In networks it leaves that somewhat absurd feeling of “two options”: either it was a Terminator, or the soldier was under some type … Read more

The cosmos has sent us a series of blue flashes for more than a decade. We now have a clue as to what they really are.

For more than a decade, the cosmos has been sending us mysterious flashes of ultra-bright blue light that appear out of nowhere and disappear in a matter of days. This phenomenon has a strange little name, but they are known as ‘luminous fast blue optical transients’ (LFBOTs), and have baffled astronomers since its discovery. Now, thanks to the analysis of one that has become the brightest ever detected, scientists believe they have solved the enigma: they are black holes devouring companion stars, and the process is extremely violent. The discovery. The team led by researchers from the University of California at Berkeley analyzed a LFBOT discovered in 2024 and named ‘AT 2024wpp’. The phenomenon turned out to be between five and ten times more luminous than any other of its kind previously observed. Astronomers used a range of space and ground-based telescopes (including Chandra, Swift, NuSTAR, ALMA, and the Keck and Gemini observatories) to study it at multiple wavelengths, from X-ray to radio. The data revealed that the energy released by AT 2024wpp was 100 times greater than that of a normal supernova. As Natalie LeBaron, a graduate student at Berkeley and first author of one of the studies, explains, “the absolute amount of energy radiated by these bursts is so large that you can’t feed them with the collapse and explosion of a massive star, or with any other type of normal stellar explosion.” An extreme cosmic feast. The researchers they propose that these flashes are produced by what they call “extreme tidal disruption.” This process occurs when a black hole (with a mass up to 100 times that of our Sun) completely destroys its companion star in a matter of days. According to the team’s reconstructions, the black hole had been absorbing material from its companion for a long time, surrounding itself with a halo of gas. In the case studied, the scientists report that, when the star got too close and was torn apart, the new material violently collided with the pre-existing gas as it fell towards the black hole, generating the intense blue and ultraviolet light characteristic of LFBOTs. According to account Robert Sanders, a researcher at the University of Berkeley, Some of the gas was ejected in jets from the poles of the black hole at about 40% of the speed of light, producing the radio emissions that scientists later detected. Intermediate mass black holes, a separate enigma. The black hole’s inferred mass places these objects in a particularly interesting category: intermediate-mass black holes. Although experiments like LIGO Black hole mergers of more than 100 solar masses have been detected, they have never been directly observed and their formation process remains a mystery. “Theorists have proposed many ways to explain how we get these large black holes,” points out Raffaella Margutti, associate professor of astronomy and physics at Berkeley and lead author of both studies. “LFBOTs allow us to approach this question from a completely different angle. They also allow us to characterize the precise location where these things occur within their host galaxy, which adds more context to trying to understand how we ended up with this configuration: a very large black hole and a companion.” A family of phenomena with curious nicknames. The first LFBOT with sufficient data for analysis was detected in 2018 and received the official designation ‘AT 2018cow’. His name led researchers to nickname him “the Cow”, a tradition that continued with later events: the Koala, the Tasmanian Devil and the Finch. AT 2024wpp, the subject of this study, has already been informally named the Woodpecker. To date, just over a dozen of these events have been identified, all located in galaxies with active star formation at distances of hundreds of millions and billions of light years. The companion star destroyed in AT 2024wpp was more than 10 times the mass of the Sun and could have been a Wolf-Rayet starthat is, very hot and evolved objects that have already consumed much of their hydrogen. TO hunting for LFBOTs. Researchers hope that the upcoming ultraviolet space telescopes, ULTRASAT and UVEX, scheduled to launch in the coming years, will revolutionize the detection of these phenomena. “Right now we find only one LFBOT a year or so. But once we have UV telescopes in space, finding LFBOTs will become routine, like detecting gamma ray bursts today,” explains Nayana AJ, researcher at Berkeley and first author of X-ray and radio analysis.

The existence of lightning remains a mystery to atmospheric physics. Austria has given us a clue to solve it

It seems unbelievable, but in the middle of 2025 one of the most common and violent phenomena of nature continues keeping many secrets. This is the case of raywhich we know how to protect ourselves from and we know that Franklin had very right with your kite. But if we ask an atmospheric physicist what exactly detonates the first spark inside a cloud to start the download, you’ll probably shrug your shoulders. The discovery. We would expect the answer to this classic meteorology question in the sky itself, but in reality it seems to be in a laboratory in Austria. It has been here where they have achieved something that seems like magic: using lasers to trap microscopic particles in the air, and almost by accident, discovering a charging mechanism that could be the ‘missing link’ in the formation of lightning in our sky. What we knew. For lightning to strike, it is necessary that there is a monstrous electric field that breaks the resistance of air, something that has a name: dielectric breakdown. The problem is that when we measure the electric fields inside a thundercloud, the numbers don’t add up: They are too low to initiate lightning on their own. This means that scientists have long suspected that the secret was in the aerosols and ice crystals that collide within a cloud. And the theory is quite clear: if a small particle could accumulate enough charge, then it has the ability to create a micro-electric field around it so intense that it would start a chain reaction. The problem is that studying a microscopic ice grain in the middle of a storm is impossible, since we can be next to it and we cannot lower the cloud to the ground either. That is why this is where this research comes in, which has found a high-tech solution with optical tweezers. The experiment. To find the answer, a 532 nm green laser was used to make lift a silica sphere just a micron in diameter. But… Why? In this case, the initial objective was to measure forces precisely, but they encountered something very strange: the laser itself that held the particle was electrically charging it. Far from being a mistake, they realized that they had in front of them a perfect tool to simulate the atmosphere in miniature. It was no longer necessary to go to a cloud to analyze it. In this way, they began to charge a particle with so much static electricity that it caused a dielectric breakdown in the air around them, discharging themselves suddenly. They had literally created a controlled micro-ray in the laboratory. The authors of the study explicitly suggest that this system is an ideal model to study the electrification of aerosols and clouds. Its importance. Until now, studying these phenomena required getting into a storm-chasing plane or relying on computer simulations. But now we have the ability to simulate these conditions in a controlled way. And it is also ideal to understand why sometimes the sky seems like it is going to break in our own heads.

Historians have been trying to understand Hitler for decades. DNA just gave us a clue about your sex life

“We didn’t know what we were going to find. It could have been the most boring genome on the planet, but it turned out amazing.” As if the promise of new (and morbid) revelations about Hitler weren’t enough to grab the world’s attention, that phrase of Turi Emma Kinga famous geneticist, has helped the documentary ‘Hitler’s DNA’ generated a huge stir even before its premiere. Logical. After all, the work is based on scientific research that reveals that the Nazi leader suffered from a genetic disorder that affected his sexuality. And that is just one of his many conclusions. Yes, Hitler again. The 20th century was prolific in wars, milestones and historical figures, but probably few arouse the fascination of Adolf Hitler. For his disastrous role as fuhrer but also because of the enormous amount of conspiracy theories and hoaxes that surround his figure. About his death, your habits and tasteshis supposed Jewish ancestry and his equal alleged offspring So many pages have been written that they would cover (several times) the bunker in which he committed suicide on April 30, 1945 with a sip of cyanide and/or a bullet. So it’s no surprise that any new revelation about him generates considerable excitement. Especially if it is one like the one that promises ‘Hitler’s DNA’a documentary produced by Channel 4 and which boasts of having thoroughly studied the DNA of the Nazi dictator. The piece premiered yesterday, Saturday, but its authors have taken it upon themselves to air their main conclusions in advance to warm things up. And although there are those who question their rhetoric or the solidity of some of their statements, one thing is clear: they have not done badly in their endeavor. Adolf Hitler’s DNA? Exact. To understand how the producers obtained a genetic sample from Hitler, we must go back to May 1945, shortly after the Nazi leader’s suicide. Among the allied soldiers who were able to access the Führerbunker There was one especially clever one, Roswell P. Rosengren, who came up with an idea: Why not take proof of the very couch on which the dictator had taken his life? No sooner said than done. The American officer cut off a blood-stained scrap and took it home. The piece was guarded by his family until 2014, when it passed to the Gettysburg History Museum. There the producers of Channel 4 found him, who had to face the following challenge: Was that really Hitler’s blood? Was there some way to establish the link, beyond Rosengren’s story? The answer was yes, although it forced them to take a new time jump (this much shorter one) to 2008, when the journalist Jean-Paul Mulders obtained a DNA sample from a relative of Hitler, a person with whom he shared paternal ancestors. Mulders’ purpose was to investigate the rumor of an alleged illegitimate son of Hitler, but in the end it served the creators of the documentary to compare the sample with the blood on the couch. The result: a perfect match. Double check which reinforced the conviction that the cloth contained Hitler’s DNA. “I thought about it a lot”. The next mission was to sequence that DNA to find out everything it hid about its owner, another far from easy task. Not so much because of the technical complexity itself but because of the enormous controversy that accompanies Hitler. In fact The Times assures that there were several laboratories that refused to collaborate in the documentary. Professor Turi Emma King, the lead geneticist on the research, also had her reservations when it was proposed. “I thought about it a lot,” recognize to the British newspaper the scientist, known for identifying years ago the remains of King Richard III. If he decided to embark on the project it was for two reasons: first, why not do it when the DNA is already being used for historical research it would mean giving a prominent role to Hitler; second, by the conviction that sooner or later someone would do it. “We wanted to make sure it was done methodically and rigorously.” So King decided to join the other main expert in the investigation, Dr. Alex Kayexpert on Nazi Germany and professor at the University of Potsdam. Clearing up unknowns. The experiment did not disappoint. As King acknowledges, the team risked not getting convincing results or anything substantial to justify the effort. Quite the opposite happened: the DNA analysis yielded some surprising conclusions that help debunk myths and expand the keys to understanding the Nazi leader. “We didn’t know what we were going to find. It could have been the most boring genome on the planet, but it turned out incredible,” relates. One of their most interesting findings is that the rumors about Hitler’s Hebrew ancestry appear to be basically that: rumors. At the time, there was speculation that the dictator’s paternal grandfather could have been Jewish (Hitler’s father, Alois, was an illegitimate son), a theory so deep-rooted that in 2022 it came to light. share it publicly Russian Foreign Minister Sergei Lavrov. He was wrong. Channel 4 analysis reveals that Hitler was of Austro-German descent and supports the family tree drawn up by the Nazis. “Confirms that the story of Jewish ancestry through his parents is false,” concludes King on CNN. Kallman syndrome. If there is a revelation that has generated interest and grabbed headlines, however, it is the one that tells us about a much more personal aspect of Hitler: his physiology. Scientists claim to have found solid evidence that Hitler suffered from some form of Kallman syndromea genetic disorder that affects the development during puberty and of sexual organs. The most common thing is that the syndrome causes hypogonadism (insufficient production of testosterone during adolescence), but as the British press has been responsible for reminding these days, it has another peculiarity: up to 10% of those who have the disorder have micropenis. Beyond the obvious morbidity of this revelation, the data is interesting because of the stories that … Read more

Trying to understand why human beings like alcohol so much, these scientists have just found a fundamental clue: drunken monkeys

More than two decades ago, Robert Dudley wondered how it was possible that we liked alcohol. In 2014, the evolutionary biologist of the University of California in Berkeley published “El Mono drunk”, a book where he explored The evolutionary roots of that transcultural hobby to alcohol. According to Dudley, it is the fans of primates to fermented fruits (rich in sugars and with a very light alcoholic content) what is behind all this. The problem, as with all the hypotheses of evolutionary biology, was to demonstrate it. Now we have found some tests. Because Science Advance magazine He has just published a study which shows that wild chimpanzees consume the alcoholic equivalent to one or two human cups. That is, exposure to this substance is regular and “probably” was also in our past as a kind, as Dudley said. How have you discovered it? The team analyzed the fruits consumed by the wild chimpanzees in Uganda and in Ivory Coast. Thus, they discovered that these 21 species had a concentration of 0.3% alcohol on average. To the extent that these animals consume about 4.5 kilos of fruit, the amount of ethanol consumed daily is more than the 14 grams that has a standard glass in the US. Of course, “by adjusting for body weight, which in chimpanzees is around 40 kilos in front of about 70 in humans, the exposure equals almost two glasses,” Explain in SINKSEY MARO, main author of the study. It is true, however, that as consumed throughout the day, researchers have not found signs of drunkenness in chimpanzees. So drink alcohol is something natural? This is a usual confusion when we put on the table lAs evolutionary explanationsbut evidently it is not prices. To start because there is nothing ‘natural’ per se. The Natural-artificial ‘distinction It is something that has very little scientific, philosophical or social basis. We have reached a point where everything is artificial. But, on the other hand, the world has changed a lot. Although the hypothesis can explain the origin of the taste for alcohol in all human societies, constant exposure to alcohol of great concentration such as the one we suffer today has nothing to do with that of our ancestors. Therefore, our taste for alcohol may have a certain evolutionary base; The abuse of ethanol and the health problems it causes are something else. Something much more dangerous.

The new obsession in gyms is also a clue about the future of the exercise

It is the New Fitness World Fever: competitions that carry exercises and, therefore, very specific training. By comparison, although these exercises settle their bases in traditional training, make crossfit or calisthenics They look outdated or rough. A mixture of unique elements (competition, aesthetics and that philosophy of overcoming and stoicism so fashionable in the latest generation gyms) has become Hyrox In a phenomenon. We analyze Some of your keys. What is it. It is a competition that combines 8 kilometers of career with 8 functional exercises of strength and resistance. The exercises are always the same and include: skiing machine, thrust and drag of sleds, Burpees With long jumps, rowing, weight transport, strides with sandbags and medicinal ball throw. That is, a devastating mixture (but with exercises available to anyone) that combines strength, resistance and general athletic capacity. Worldwide success. Born in 2017 in Germany, in recent years he has experienced a great impulse (globally, more than 650,000 athletes train for competitions, and in 2025 more than 80 global careers are held in more than 30 countries and 85 cities). It currently has a wide margin of future growth: for example, it has just reached areas such as Canada, Australia and the Middle East, and the World Championships of discipline. Spain wants Hyrox. Spain is one of its largest areas of growth. The last edition, in Bilbao, congregated More than 8,000 competitors. In Malaga 2025 11,000 athletes from 40 countries participated, while in Hyrox Barcelona 2025 13,000 athletes were registered and 10,000 finished. In the 2024-2025 season, the discipline exceeded the 40,000 athletes registered in Spainconsolidating the country as one of the European referents in this discipline. The number of participants has grown by 1,900% since the first major national event in 2021, when 2,000 athletes were recorded. The secret of his fame. Why do you like a competition so much that is essentially a traditional fitness vitamin version? His hybrid nature It has a lot to do: the demanding of the competitions forces athletes to prepare not only force, with lifting and movements of large weights, but also resistance, with those eight kilometers that must be traveled between evidence. That makes it a Very complete and varied trainingand where no discipline should not be put aside. And also, without great technical demands: everyone can push a sled. On the other hand, the competition allows group or couples categories, which makes it more affordable. Class pride. Hyrox is one Registered trademarklike so many others associated with fitness. From the very Crossfit itself, which is not a generic word but a brand associated with official competitions and training, the popular Zumba, which has unleashed a real plague of imitators (in the end, it is the old man Gym-Jazz eighties in steroids). All this going through competitions that were ahead of Hyrox, such as Spartan Race or Ironman, and training systems such as F45 Training or Orangetheory Fitness. What does all this mean? That to train and compete in Hyrox you have to pay the fee that Hyrox architects decide to pay. This leads to official gyms and competitions of considerable price (the minimum cost of a career is usually around 70 euros), and by the hand, to the transformation of training into a piece of exhibition of good economic health that distance to Hyrox of formats (not registered) such as calistenia, which can be trained outdoors. Hyrox not only allows to show off a healthy way of life but also a well oxygenated portfolio. Training as Lifestyle. Linked to this last aspect, we have sport as an exhibition mode of a way of life, also vent, to which Hyrox international competitions help, in countries like Berlin or Rome. A circumstance that allows “healthy tourism”: travel to compete, and without neglecting what affirms Álvaro Taracena, CEO of the brand in Spain: “Nobody here looks at you badly for lifting less weight (…) to do something more dynamic, in the end you make friends with whom take“ Hyrox for Influencers. At a time when absolutely everything has to be Instagrameable To succeed, Hyrox has the elements to do so: It is completely training gamified and aimed at a specific objective (compete and improve brands in competitions, no abstractions such as “health”).

We have a new clue about depression and we have found it in an unsuspected place: body temperature

Depression is something that goes beyond our brains. Like many other diseases, this psychological ailment is manifested in other aspects of our physiognomy. For example, in our body temperature. Temperature and depression. A study has identified A relationship between body temperature and depression. The team responsible for the analysis observed a positive relationship between the variables, that is, that the appearance of depressive symptoms was linked to a higher body temperature among the participants. The relationship was proportional. The severity of the symptoms, the greater the body temperatures were also. They also observed an apparent relationship between the variability of temperatures and depressive symptoms, but this did not show being statistically significant, so conclusions cannot be extracted in that aspect. Beyond the statistical incidence is little What is known of this relationship. For example, the equipment indicated that it is still an enigma if this increase in body temperature could be due to a loss of control capacity, an increase in temperature generation through metabolic processes, or if it was a combination of factors. More than 20,000 participants. To carry out the study, the team compiled information from 20,880 participants from 106 countries. During the study, which lasted for seven months in 2020, the participants carried a thermometer device to measure their body temperature and daily reported temperature and symptoms of depression. “Let us know, this is the biggest study to examine the association between body temperature (measured both self -assess and through portable sensors) and depressive symptoms in a geographically wide sample,” explained in a press release Psychiatrist Ashley Mason, co -author of work. The study It was published in the magazine Scientific Reports. An old suspicion. Although it is probably the most massive, this is not the first analysis that indicates this relationship. A study published in 2003 He pointed to the existence of this relationship and its possible link with the 5-HTT protein, the “serotonin transporter”. Another important indication has to do with the drugs usually used in the treatment of depression, selective serotonin reuptake inhibitors (SSRI) and serotonin and norepinephrine reuptake inhibitors (SNRI). In recent years, various studies have proven that these compounds reduce thermal tolerance of those who consume them. The main studies in this regard were analyzed In a literature review published in 2022. Correlation and cause. The present study finds a link between temperature and depression but does not indicate the possible form of the causal direction, if there were. It is impossible to determine, through known data if depression causes an increase in body temperature or if a high body temperature can increase our risk of appearing depression. Nor is it possible to rule out that there is an underlying cause of both that the analysis does not see: inflammatory stress or processes could independently cause both depressive symptomatology and an increase in body temperature. Cold or heat as therapy? Understanding what is happening can help us better understand depression and, therefore, bring us closer to the tools we are looking for to fight it. Until now the heat had been used to improve the patient status. These types of therapies could make sense through a “rebound effect”, helping the body to recover its capacity for thermal self -regulation, Add the equipment.

We had been trying to know what neurostrogens served why they served. We have just discovered a clue: they regulate the appetite

In recent years we have seen progress in the study of the hormones responsible for regulating our appetite and the feeling of satiety, hormones such as those that transmit from the stomach to the brain the information that we have already consumed our ration of food and we can stop. However, now we just found one of these hormones in an unexpected place, in hormones that until now we associated mainly with reproduction. From the stomach to the brain. A Japanese researchers team He has found A relationship between neurostrogens and appetite regulation. Neurostrogen. The Estrogens They are hormones that we usually associate mainly with female reproduction. In this context, aspects such as the development and maintenance of female sexual characteristics regulate. But this “family” of hormones has a diversity of members that cover other contexts. For example we can find the phytostrogen produced by plants or neurostrogens. The latter are produced by the brain, as their name suggests and until now they represented a mystery in our biochemistry since we do not know which or what their exact functions are. Looking for an answer. The team I investigated precisely The role of these brain hormones. For this they turned to mice in a laboratory. They compared several groups of mice, including some without the capacity to produce estrogen; and others to whom the production of neurostrogens had been inhibited. The latter was eliminated by aromatase, an enzyme used by the brain to synthesize these hormones. They thus verified that the group of mice that lacked ovaries and those without aromatase showed a greater body mass and greater food consumption compared to the mice of the control group. The team Then he reactivated The gene linked to aromatase, returning the enzyme to its brains. They saw that the mice went on to consume less food. MC4R. The team found that these mice to whom the ability to synthesize aromatase had been returned and with it neurostrogens showed a “marked increase” in the expression of the melanonortine 4 (MC4R) receptor, a receptor known for its role in the regulation of food consumption. This led the team to conclude that the neurostrogens produced through aromatase were involved in the expression of the receiver and that it was through it that were able to “suppress” the feeling of hunger. The role of leptin. The study, explains the responsible team, also indicated that neurostrogens could also increase the ability of the brain to leptin, one of the hormones whose function we already knew related to the regulation of appetite. “We observe that mice with restored neurostrogens responded more effectively to leptin treatment,” explained in a press release Takanori Hayashi, co -author of the study. “This may be due to the fact that neurostrogen increases the natural response of the body to the mechanisms that suppress appetite.” The details of the study were published In an article In the magazine The Febs Journal. The eye put into treatments. The team responsible for the study Mention the possibility that this discovery opens new therapeutic paths focused on development detracts for weight loss. They also point out that understanding the physiological function of neurostrogen could also help us find ways to regulate estrogen more precisely in our bodies, for example in contexts such as menopause or postpartum.

Genetics offers some clue to answer the eternal question: What the hell goes through my cat’s head?

Who has lived with a cat has probably intrigued more than once by the sometimes incomprehensible Gatuna Psychology. Now, a project seeks to respond to some of the mysteries that surround the behavior of these felines in the hope that their psychology is not, after all, completely impossible to understand. Cats are sought. And the first step to achieve this is in Create a database with information about numerous cats of various races and contexts. It is precisely what the Darwin cat initiative team is doing, or Darwin’s Cats. Plans. He objective of this project It is to collect 100,000 cats enrolled in June 2026, although they have not yet reached the 10,000 mark. The team seeks to gather information on the behavior of felines through a questionnaire and information about the genetics of each individual. For the latter, participants will have to send a hair sample from the animal next to the questionnaire. Combining these data, the team hopes to obtain the highest database of its kind to investigate not only in the behavior of these domesticated animals, but also expand our knowledge about their health. Who wants to register your pet, yes, you must pay a donation of about $ 150, in order to finance the investigation. In Xataka Communicating with our cats has always been a complex task. A study has discovered the key: flashing Darwin’s ark. This project is not the first in its style for the team that undertakes it. The initiative is part of the work of the Darwin Ark Association (Darwin’s Ark), which a few years ago made Similar work With dogs. Behind the project There is a team of researchers linked to the Chan School of Medicine of the University of Massachusetts and Broad Institute. Inquiring in feline psychology. Perhaps because of the contrast between dogs and cats or perhaps because their behavior really is strange to us, the psychology of cats has intrigued many throughout the long history of coexistence between felines and humans. So strange is sometimes the behavior of these animals that we have come to apply evidence aimed at detecting psychopathy trends in these animals. In recent years, this field of study has put some emphasis In the genetics of cats when confirming some ideas about the existence of hereditary features in the personality of these animals. A quite widespread notion but that we are still understanding. {“Videid”: “x95dxwi”, “Autoplay”: fals, “Title”: “The strongest animal measures 1mm so are the most fearsome animals”, “Tag”: “Webedia-prod”, “Duration”: “343”} Health issue Understanding the genetics of these mammals goes beyond finding patterns in their behavior. It can also help us when detecting genetic components of some of the diseases that affect cats and thus be able to find ways to improve veterinary attention to these animals. Perhaps they can even help us prevent or cure some of the diseases and disorders that affect very present animals in our environment.
