Someone forgot a bag of cheetos in the largest cave chamber in the US. The problem is chaos to the ecosystem that comes after

That humans can generate The biggest chaos in ecosystems that surround us I think it is out of any doubt. However, already a difference from other animals, no matter how large the error is, We are able to repeat it In a short time. Therefore, what happened in one of the most fascinating areas in the United States is a good example. Even if it is A simple check of Cheetos. The importance of Carlsbad’s caverns. Located in the state of New Mexico, it is about A set of more than 119 underground cavesof great geological and ecological importance. Formed by the acid water action that dissolved the limestone over millions of years, these caverns stand out for their vast network of passages and cameras, including the famous “great room”, one of the largest underground cameras in the world. These unique geological formations include impressive stalactites, stalagmites and columns, hence it is of great scientific interest to study the processes of training of caves and the geological history of the southwest of the United States. However, this enclave named World Heritage by UNESCO has also become a must of mass tourism. A bag. As The National Parks Service explained in an article (NPS), what happened should make all future tourists think after a distracted visitor left a bag of Cheetos in the depths of the Carlsbad caverns. Apparently, the snack dropped into the historic great room, the largest cave chamber by volume in North America, the same one that can only be accessed by walking around an hour underground. A pump to the ecosystem. Once there, the bag can rot in the wells of the wet cave. In other words, those small “cheese” snacks stranded in the cave can make a small expansive wave through the local ecosystem. “The processed corn, softened by the moisture of the cave, formed the perfect environment to house microbial life and fungi. The crickets, mites, spiders and flies of the cave are soon organized in a temporary food network, dispersing the nutrients to the cave and the surrounding formations. The mold extends to the nearby surfaces, gives fruit, dies and smells bad. Count the NPS In a publication. A much bigger problem. In the same article it is denounced that “at the scale of the human perspective, a spilled snack bag may seem trivial, but for the life of the cave the world can change,” they emphasize. “Great or small, we all leave an impact wherever we go. Let’s all leave the world in a better place than we find,” adds the center. Apparently, the rangers had to perform an arduous follow -up task to carefully eliminate any rest of the garbage and mold from the surface of the cave, hoping to avoid any lasting impact on the cave. Garbage and natural environments. One of the great scourges of The National Parks of the United States It has to do with what visitors “bring” and leave when they leave. That garbage throws chilling numbers: more than 300 million people visit the national parks every year, generating almost 70 million tons of garbage. And of all enclaves, the caves take the worst part. The reason? They are more vulnerable because they are isolated from the outside world and house a rich variety of highly adapted, endemic and sensitive organisms. If a new seasoning is added to the equation, call cheetos or similar ones, the result can radically alter the balance of biodiversity. The example of the Lascaux cave. Possibly, it is the most famous case and the clearest example of how we are capable of alter an environment of this type. Discovered in France in 1940, they immediately became famous for their cave paintings dating from 17,000 years ago, one of the best samples of prehistoric art. However, after opening to the public in 1948, mass visits began to negatively affect the delicate microclimate of the cave. Apparently carbon dioxide exhaled by visitors, along with moisture and changes in temperature, began to cause visible damage to paintings, such as the appearance of fungi and algae on the walls. These changes put at risk the conservation of paintings, some of the most important in humanity. Closed forever. Faced with this deterioration, in 1963 the French authorities made the decision of Close the Lascaux cave to the public To protect the paintings. Since then, only a very limited number of scientists and conservation experts have had access to it. In fact, to allow the public to continue appreciating the art of Lascaux, a replica known as Lascaux II was created, which reproduces the main cameras and paintings of the original cave. This measure, protecting the historical value of the caves with steel doors and security cameras, has allowed to preserve the artistic heritage of Lascaux while maintaining its educational and cultural value. Maybe we should do the same with all caves with historical value. Although before it should be reviewed that no one has left a snack.

Transform smartphones sensors into an antimatter chamber

One of the reasons why Antimatter is so interesting Not only for particle physicists, but also for the people to whom we are passionate about science, is that the tools we have They still do not allow us to understand what role he played in The origin of the universe. However, the enigma does not end here; Nor do we know what laws govern the faint line that delimits the imbalance between matter and antimatter in the cosmos. Before moving forward, we are worth stopping for a time to briefly review what antimatter is and what makes it so peculiar. Actually, it is nothing more than a form of matter constituted by antiparticles, which are particles with the same mass and spin as the particles with which we are familiar, but with opposite electric charge. In this way the antiparticle of the electron is the positron or antielectron. And the proton antiparticle is the antiproton. The antimatter has a surprising property: when they come into direct contact with the matter, both are annihilated, releasing a large amount of energy in the form of high-energy photons, as well as other possible particle-antiparticle pairs. It is currently being studied in much of the research centers specialized in physics of most important particles in the world in the hope that knowing it better helps us understand some of the mysteries of the cosmos that remain out of our reach. The AEGIS experiment demonstrates how ingenious particles are physicists The sensors of the cameras of our mobile phones are very valuable when it comes to unraveling the mysteries of the antimatter. This a priori statement may seem strange, but it is reliable. And is that a team of researchers from the Technical University of Munich (Germany) who works side by side with scientists from the Cern (European Organization for Nuclear Research) has designed an experiment that, precisely, resorts to this strategy. It’s called aegis (Antimatter Experiment: Gravity, Interferometry, Spectroscopy or ‘Antimatter experiment: gravity, interferometry, spectroscopy’) and is extraordinarily ingenious. AEGIS uses modified sensors of mobile phone photo camera to identify the points where antimatter and matter are annihilated In the cover photography of this article we can see what the device they have built. Broadly the purpose of this experiment is to study the interaction between gravity and antihydrogen, which is a form of antimatter, to verify if the latter behaves before gravity in the same way as ordinary matter. As we can deduce from its name, it resorts to interferometry and spectroscopy techniques to carry out its objective, but the most surprising thing is that the detector uses modified sensors of camera photo cameras to identify in real time the points in which the antimatter and the subject are annihilated. “For AEGIS to work properly we need a detector with an incredibly high spatial resolution. And the smartphones camera sensors have pixels of less than 1 micrometer,” Francesco Guatieri explainedmain investigator of the experiment. “We have integrated 60 camera sensors in our detector, which allows you to reach a resolution of 3,840 megapixels, the largest amount of pixels of any image detector to date.” It is spectacular. Let us trust that Aegis fulfills its mission and these scientists manage to understand a little better how the interaction between antimatter and gravity is.

US House approves immigration detention law that could be the first that Trump enacts

The US House of Representatives on Wednesday gave final approval to a bill that requires the detention of migrants who are in the country without permission and who have been accused of theft and violent crimes, the first measure that President Donald Trump can enact it, after Congress—with some bipartisan support—moved quickly in line with the president’s plans to toughen measures against illegal immigration. The passage of the Laken Riley Act, named after a Georgia nursing student who was murdered last year by a Venezuelan, shows how dramatically the political debate over immigration has shifted to the right following Trump’s election victory. . Immigration policy has often been one of the most entrenched issues in Congress, but a crucial group of 46 politically vulnerable Democrats joined Republicans to pass the strict proposal by a vote count of 263 in favor and 156 against. . “For decades, it has been nearly impossible for our government to agree on solutions to problems at our border and within our country,” said Republican Senator Katie Britt. He noted that it is likely to be the “most significant immigration bill” that Congress has passed in nearly three decades. However, the bill will require a massive increase in the capabilities of Immigration and Customs Enforcement (ICE), but does not include any new funding. Meanwhile, the new president has issued a series of executive orders aimed at sealing the border with Mexico to immigration and ultimately deporting millions of migrants who lack permanent legal status in the United States. On Wednesday, Trump also canceled refugee resettlement and his administration has said it intends to prosecute local law enforcement officials who do not comply with his new immigration policies. Republican congressional leaders have made clear that they intend to follow the same path, although their biggest challenge will be finding a way to approve funding to actually implement Trump’s strict plans. “What he’s doing is starting what will ultimately be our legislative agenda,” said House Speaker Mike Johnson. House Republicans initially passed the legislation last year with the support of 37 Democrats in a move intended as a political rebuke to then-President Joe Biden’s handling of the southern border. He then languished in the Democratic-controlled Senate. This year, Republicans, now in control of both houses of Congress, have made this their top priority. When it came before the Senate, 12 Democrats voted in favor of the measure, and when the House voted on a version of the bill earlier this month, 48 Democrats supported it. A majority of adults in the United States favor deporting immigrants convicted of violent crimes, according to a recent poll by the NORC Center for Public Affairs Research and The Associated Press. However, only about 37% of U.S. adults favor deporting migrants in the country illegally who have not been convicted of a crime. “While the bill is not perfect, it sends a clear message that we think criminals should be deported,” said Rep. Tom Suozzi, a New York Democrat who has urged his party to support stricter enforcement of the law. immigration law. Under the bill, federal authorities would be required to detain any migrant arrested or charged with crimes such as shoplifting. The scope of the proposal was expanded in the Senate to also include those accused of assaulting a police officer or crimes that injure or cause the death of someone. The bill also gives state attorneys general standing to sue the federal government for damages caused by federal immigration decisions. This gives states new power in immigration policy when they have already been trying to counter presidential decisions under the Trump and Biden administrations. Democrats unsuccessfully tried to have that provision removed from the bill in the Senate, saying it would inject even more uncertainty and partisanship into immigration policy. Ultimately, even the Trump administration will likely struggle to implement the new requirements unless Congress follows up later this year with funding. Republicans are currently planning how to push their priorities through Congress through a party-line process known as budget reconciliation. They have estimated the cost of funding Trump’s border and deportation priorities at approximately $100 billion. Trump has “established the largest domestic logistics undertaking of our lifetimes, which is the deportation of the majority of aliens who are in the United States illegally,” said Ken Cuccinelli, who led U.S. Citizenship and Immigration Services during the Trump’s first term, to a Senate panel recently. Cuccinelli noted that it would require an increase in immigration judges, prosecutors and other staff, but Trump has also paved the way for using military assets, bases and other resources to carry out mass deportations. The Department of Homeland Security has estimated that the Laken Riley Act would cost $26.9 billion in the first year to implement, including an increase of 110,000 ICE detention beds. Most Democrats criticized the lack of funding in the bill as evidence that it is a piecemeal approach that would do little to fix problems in the immigration system but would burden federal authorities with new requirements. “The authors of the bill stated that it would result in the arrest and detention of dangerous criminals, but it will not because it is a completely unfunded mandate,” said Democratic Senator Chris Murphy. Others expressed concerns that the bill would deprive migrants, including minors or beneficiaries of the Deferred Action for Childhood Arrivals (DACA) program, of due process rights. Senator Alex Padilla said federal authorities would now be forced to prioritize detaining migrants arrested for minor crimes such as shoplifting, rather than those who commit serious crimes. Overall, there is no evidence that migrants are more likely to commit violent crimes. Several studies have found that immigrants commit crimes at lower rates than those born in the United States. Groups that advocate for restrictive immigration policies dispute or dismiss those findings. But Republicans pointed to the bill’s namesake, Laken Riley, and how she was murdered by a Venezuelan migrant who had previously been arrested by local authorities but released while his … Read more
