Scary sounds in space
An Investigation into the Chilling Sounds of Other Universes It is common to portray space, which is considered to be the last frontier, as a nothingness that is quiet and where no one can hear you scream. On the other hand, this is not a completely correct statement. We now have access to some of the most horrifying and awe-inspiring noises that come from the depths of the cosmos, and this is all because to the progress that has been made in technology and the inventiveness of scientists working for NASA.

The Moon becomes a mine of gold... and other metals. AI-Generated.
Space exploration has long focused on reaching very distant destinations, but now there is a race to exploit new frontiers with the extraction of their minerals. Neil Armstrong's first walk on the Moon in 1969 was part of a strategy to beat the Soviets in the space race, a victory of imagination and innovation, not an attempt to mine precious metals. No one knew if there was water in that dusty celestial body. What a difference a generation makes... Mysterious and beautiful, the Moon has been a source of admiration and inspiration for humanity for millennia. It is now the center of a space race to extract minerals to power our future: smartphones, solar panels and possibly even a colony of earthlings. "We know there is water on the Moon, which changes the game for the Solar System. Water is rocket fuel. It is also fuel for life and agriculture. So exploring the Moon commercially is a first step to making it part of what that humanity sees as our world," says Bob Richards, CEO of Moon Express, one of 25 companies bidding to win the $30 million Google Lunar X prize. The Californian company is among the top three in the race. The others are Astrobiotic, from Pittsburgh, and Moon Team, from Barcelona. Google's first prize, of US$20 million, will be awarded to the first private company to put a robot on the Moon, successfully explore the surface by moving at least 500 meters and send high-definition video to Earth. The second prize, of US$5 million, goes to the second company to complete the same mission, with additional prizes for teams that travel more than 5 kilometers or find water. The deadline is 2015. But $30 million is a relatively small amount to fund a lunar mission. The competing companies have business models far beyond the Google prize, with the real prize being the potential treasure trove of valuable minerals. Does the Moon have an owner? "The most important thing about the Moon is probably what we haven't even discovered," Richards says. "But what we know is that there could be more platinum group metals on the surface of the Moon than in all the reserves on Earth." But can anyone own the Moon, and what happens if multiple companies and countries manage to get there? Under the 1967 outer space treaty, no nation can own the Moon, and most people believe that extends to individuals and companies. But would-be lunar miners may have something like property rights. And there is an advantage in arriving first and claiming rights. "The treaty does not allow appropriation, but open access exploitation is encouraged," notes space lawyer James Dunstan. "You can't own it, although you can use it, but how do we strike a balance?" China has plans to send a probe to the moon this year and astronauts in 2020. Because China's lunar plans are more ambitious than most, some fear it could gain too much control. Dunstan does not believe that China will flout international law to dominate space. "Trade sanctions would be very harsh if a country or corporation appropriated other people's assets." If Moon Express and others get it right, it is conceivable that in the future the lunar surface will host a colony of mining robots and astronauts who would use it as a base for further exploration of the solar system. Richards believes humans will discover ways to live permanently on the Moon. "We are becoming a multi-world species. The first traces of human beings on Mars will arrive in our era, in the next 10 to 20 years," he adds. "People will be transformed. They will merge with their technologies. And what we call human will be redefined as we seek to reprogram our bodies to live longer and find machines capable of working symbiotically with us to cure diseases." "So what we consider human today will continue to evolve." A space without pollution Moon Express, whose offices are at NASA's Ames Research Center, is financed by businessman Naveen Jain. Jain says the location is key, because it is in Silicon Valley, which he believes will become home to space pioneers. "We are those crazy people who think that every idea is crazy, until we make it concrete and then people say 'of course,'" he points out. So, if we will one day live on the Moon, shouldn't we be worried about contaminating it? Won't robot armies ruin our real estate future? Margarita Marinova, a planetary scientist at NASA, believes that we will not make the same mistakes in space as we did on Earth and that man cannot afford to explore space without taking advantage of local resources to survive. "For me it's hard, because I see these planets as beautiful and pristine as the Earth is no longer, so the idea of mining is a little difficult," she admits. The Moon's potential resources are vast. M. Darby Dyar, a professor of astronomy at Mount Holyoke College, Massachusetts, says ice reserves in the Moon's polar regions probably come from comets that collided with the Moon in the last 4 billion years, and that future miners Lunars could strike it rich with precious metals in ancient lunar rocks. But even if no company meets the 2015 deadline to win the Google award, Dyar says it has already borne fruit. "I lived through the excitement of the Apollo era, my father helped design thrusters on the lunar landing modules, and those remembered feelings of patriotism and wonder about the universe led me to lunar science in the first place." "When I give a girl a meteorite and tell her it's 4 billion years old, her entire frame of reference changes, and that's what science should do. Not everyone wants to be a scientist, but everyone is excited about learning to respect and understand their progress. "Competitions like this bring science to the public's eyes. Where better than on the Moon, which seems to be so close to us?"

What is the origin of oil (and no, it does not come from dinosaurs) . AI-Generated.
Known as “black gold”, it is a mixture of hydrocarbons, compounds that contain in their molecular structure mainly carbon and hydrogen. It is a motor of today’s society, a motive for wars, and one of the main drivers of climate change.Every day more than 80 million barrels of oil are produced in the world, whose name comes from the Latin and means “stone oil”. This viscous liquid known as “black gold” is a mixture of hydrocarbons, compounds that contain in their molecular structure mainly carbon and hydrogen. Oil is the product of a process of processing over millions of years. But where does it come from?Most scientists are in favour of a theory and assure that the origin of oil “is well understood”. But that didn't stop some false beliefs from circulating... The myth of dinosaurs It is estimated that about 70% of the current crude deposits were formed in the Mesozoic or Mezozoic Era, which extended between 252 and 66 million years ago. The Mesozoic, which is divided into the Triasic, Jurassic and Cretaceous periods, is also known as the reptile era and in it dinosaurs had their apogee. This could explain why misinformation has circulated. “For some strange reason, the idea that oil comes from dinosaurs has remained in many people. But oil comes from trillions of tiny algae and plankton,” said Reider Müller, a geology professor at the University of Oslo. No one knows for sure how this myth was born, but it also circulated in Latin America.BBC Mundo asked two Mexican experts if they were aware of that belief. “Yes, it’s a misconception, but very common,” said Darío Solano and Iza Canales, professors at the Faculty of Engineering at the National Autonomous University of Mexico, UNAM, in the Division of Earth Sciences. “At least within our community, we can identify that many of the rocks that generate hydrocarbons are found in layers of the Jurassic, which is a geological time period that is usually associated with dinosaurs, and that is the relationship that has helped reinforce the idea that this is their origin,” Solano explained. “It is important that these myths are dismissed, firstly to help society as a whole eliminate ignorance of a substance of common and widespread use, in short, only by general culture. Secondly, by advancing in understanding the origin of this resource, it will be possible to advance in the development of new technologies or uses,” added Canales. How oil is formed The protagonists in the history of the origin of oil are not the big reptiles but tiny beings.The most accepted theory about the origin of oil is the organic term, according to which the resource originated from the decomposition of the remains of animals and microscopic algae accumulated on the bottom of seas and lagoons. This theory indicates that fine sediments and organic residue, mainly terrestrial or marine vegetables, are deposited in a basin. After certain processes the kerogen is formed, which is a mixture of these organic materials, and after a long time the pressure and temperature are increased, eventually forming hydrocarbon chains, the scientists of UNAM explained. The accumulation of other geological layers on the deposits of organic matter generates pressure and temperature conditions that facilitate the action of anaerobic bacteria to slowly transform organic material into hydrocarbons with small amounts of other elements. “In a simplified way, we can think of cooking our mixture of materials in an express pot (i.e. with certain pressure and temperature conditions) for a long time, until the original material is broken down into carbon and hydrogen chains. Something similar is happening in the basement. Then the material needs to migrate from the rocks where it was cooked to the rock that will store it,” explained Mexican experts.This theory is one of the most accepted, since all the oil deposits are found in sedimentary land and, in addition, there have been found fossil remains of animals and plants. Where does the energy in oil come from Oil can also come from the processing of organic material from ancient forests. Within organic theory it is understood that any type of organic material can be present. In fact, the kind of hydrocarbon that is obtained from kerogens rich in terrestrial plant matter is associated with gas deposits, Mexican scientists added. And here's another myth to clarify. Is the energy in oil the solar energy captured in photosynthesis by the phytoplankton (plant organisms) and transferred to the zooplancton (animal organisms)? “No, this is a misconception,” said Canales, adding: “The energy we obtain today from oil is obtained by the oxidation (combustion) of hydrogen and carbon (hydrocarbons) chains.” “It’s true that energy and matter are interchangeable, but to say so sounds like phytoplankton and zooplancton are solar batteries. It can rather be thought of as an analogue to how humans can eat many things and the body transforms food by breaking it down in our digestive system through another process of oxidation (digestion) and our body takes advantage of those simpler components at the cellular level,” Solano added. IMAGES Alternative theories Some scientists held in the past that oil has an inorganic origin and is formed in the depths of the Earth without the need for remains of living organisms. Several of these theories were proposed as early as the 19th century, for example by Dmitry Mendeleev, the Russian chemist who published the first periodic table of elements. Inorganic theories argue that inside the Earth's mantle, coal may exist as hydrocarbon molecules, mainly methane, and a large amount of hydro-carbons found in oil may be generated by processes that do not regulate organic fossils. Inorganic theories argue that inside the Earth's mantle, coal may exist as hydrocarbon molecules, mainly methane, and a large amount of hydro-carbons found in oil may be generated by processes that do not regulate organic fossils. The Asteroid That Ended the Dinosaurs Also Generated a Monstrous Earthquake These hydrocarbons can migrate out of the mantle to the terrestrial crust to escape to the surface or remain in waterproof layers, forming oil deposits. One version of these theories is that of the Austrian astrophysicist Thomas Gold (1920-2004), who was a professor of astronomy at Cornell University. Gold published a study in 1992 in PNAS, the journal of the American Academy of Sciences, which he later expanded into a book with the same title, Deep Hot Biosphere. For him, hydrocarbons on Earth are not the by-product of biological waste (“fossil fuels”), but were a common constituent of the materials from which the Earth was formed about 4.5 billion years ago. Gold acknowledged that the same hypothesis had already been supported in the 1950s by Soviet scientists. The theory of the inorganic origin of oil is not accepted by most scientists “We dare to speak on behalf of our fellow academics and scientists to say that the theories of inorganic origin have not been successfully tested and that in this way it has not been possible to generate hydrocarbon in a laboratory,” said UNAM experts. One last doubt? Given that the organic theory of the origin of oil is the most accepted, some readers might ask themselves this question. If dinosaurs lived at the same time as the formation of oil in the Mesozoic, it could have happened that their remains, organic matter of some dinosaur, fell to the bottom of the sea or lagoons and underwent a process of compression and transformation turning into oil.“In fact, we could say that any organic matter could be present in oil generation,” said UNAM experts. “ it is important to mention that oil generation is a very delicate process, and it requires very large volumes of matter, which were possible to reach only by the large volume of plankton in the sea, so volumes from other sources are not so significant,” they concluded.

Why Cars Are Evil
Owning a car can make for a nice luxury. It’s private and more freeing than the alternatives, and to live in some cities, it’s all but a necessity that you have one to get around in. This article is not meant to criticize individuals for owning cars. It’s often the best decision for them. However, if one could design a city to be car-centric versus having well-developed public transportation, there’s no question that the latter is a much better aim than the former. By every conceivable metric, cars extract an unnecessary cost when compared to the alternative.

The last tree
The village of Verde lay nestled in a valley that once boasted lush forests and flowing rivers. But those days were long gone. Deforestation and climate change had turned the land into a dry, barren place, with only one tree remaining—a towering oak that stood as a lone sentinel against the relentless march of time and environmental decay. Twelve-year-old asha had grown up hearing stories from her grandmother about the forest that used to thrive around Verde. The oak tree, known as the Guardian, was the last of its kind, a relic from a bygone era when nature and humanity coexisted in harmony. Every day after school, Asha would visit the Guardian. She felt a deep connection to the tree, often sitting beneath its sprawling branches to read or simply to think. It was her sanctuary, a place where she could escape the harsh reality of a world plagued by environmental degradation. One particularly dry summer, Asha noticed the Guardian's leaves were turning yellow and brittle. Panic gripped her heart. She rushed home to her grandmother, the village's unofficial historian and storyteller. "Grandma, the Guardian is dying," Asha said, her voice trembling. Her grandmother's face grew somber. She had feared this day would come. "The land is thirsty, child. The climate is changing, and the rains are not coming as they used to. The Guardian is struggling to survive." Asha refused to accept this fate. "There must be something we can do," she insisted. Her grandmother thought for a moment, then nodded. "There might be a way. The tree needs water, and not just any water, but the purest we can find. We must create a system to bring water from the distant mountains where streams still flow." Asha's eyes sparkled with determination. "I'll do it, Grandma. I'll save the Guardian." With the help of her grandmother and some villagers who still remembered the old ways, Asha began constructing a simple irrigation system. They used bamboo and clay pipes to channel water from the mountains to the village. It was hard work, and the scorching sun made the task even more challenging, but Asha's determination never wavered. The village was initially skeptical. "It's just a tree," some said. "What difference can one tree make?" But as they saw Asha's unwavering dedication, more villagers joined the effort, bringing their skills and labor to the project. Finally, after weeks of relentless work, the system was complete. Water trickled down from the mountains, flowing through the pipes and into a makeshift reservoir near the Guardian. Asha carefully watered the tree, her heart filled with hope. The change was not immediate, but slowly, the Guardian began to show signs of recovery. New leaves sprouted, green and vibrant. The tree seemed to stand taller, its branches spreading wide as if embracing the sky. The villagers, inspired by the tree's resilience and Asha's determination, started planting new trees around the Guardian, using the irrigation system to nurture them. As the years passed, the once-barren valley began to transform. New trees took root and flourished, and the air grew cooler and cleaner. Wildlife returned, drawn by the renewed habitat. The Guardian stood at the center of it all, a symbol of hope and a testament to what could be achieved through collective effort and a deep respect for nature. Asha, now a young woman, often sat beneath the Guardian with her own children, telling them the story of how the last tree had almost died and how the village had saved it. The tree had given them more than just shade and fruit; it had given them a reason to believe in the future. In the end, the Guardian was not just the last tree—it was the first of many in a reborn forest, a living reminder of the power of hope, community, and the enduring bond between humanity and the environment.ha
