Scientists descend for the first time into the Well of Hell | Digital Trends Spanish

The Well of Hell is one of the most fascinating natural formations on the planet. It is located in the eastern Al-Mahra province of Yemen and is about 30 meters wide and 112 meters deep. Its most “official” name is Pozo de Barhout, and for centuries it has been feared by the locals, since various legends and stories about paranormal events are told about it. In June, the Yemeni authorities assured that they did not know what could be in the grave and recognized that it could be millions of years old. Now, a team of cavers from the Oman Cave Exploration Team (OCET) carried out what is considered the first descent to the bottom of the enigmatic shaft. AFP.Inside, the exploration team found snakes, dead animals and also cave pearls. "There were snakes, but they don't bother you unless you...

3D-printed eco-friendly alternative to Wagyu meat | Digital Trends Spanish

A team of scientists from the University of Osaka in Japan has managed to 3D print a lab-grown steak that they say looks a lot like Wagyu beef. According to the researchers, it would be a sustainable and ecological alternative to imitate this traditional meat, known throughout the world. The team in charge harvested two types of stem cells from Wagyu cows, incubated them, and then turned them into muscle, fat and blood vessel cells. Thus, the end product is a three-dimensional, five-by-ten-millimeter stack of a high-fat fillet that has a structure similar to that of Wagyu meat. "Using the histological structure of Wagyu meat as a model, we have developed a 3D printing method that can produce complex custom structures such as muscle fibers, fat and blood vessels," lead author Dong- Hee K...

They discover more than 7 thousand chemical formulas in beer | Digital Trends Spanish

Although beer is one of the most consumed and popular beverages in the world, scientists are still discovering chemical compounds that contribute to the flavor and aroma that characterize its different versions. Now, a group of German scientists has analyzed more than 400 commercial beers from 40 countries, discovering at least 7,700 different chemical formulas and tens of thousands of unique molecules. How they did it? To find this large number of chemical formulas, the researchers used a new method that allows a sample to be analyzed in just ten minutes. "Beer is an example of enormous chemical complexity," says co-author Philippe Schmitt-Kopplin of the Technical University of Munich and the Helmholtz Center in Munich. “And thanks to recent improvements in analytical chemistry, potent...

They beat the record for decimals to calculate the number pi | Digital Trends Spanish

A team of researchers from the University of Applied Sciences of Graubünden (FHGR), in Switzerland, managed to break the world record for decimals of the number pi, which is traditionally known as 3.1416. Now, the college claims it broke the record by calculating 62.8 trillion digits of pi. In this way, they leave behind the previous brand that belonged to Timothy Mullican, who was able to calculate up to 50 billion digits and who was recognized last year for his work. The Swiss university noted that it took 108 days and 9 hours to perform the new calculation, a time that is 3.5 times faster than Mullican. It is also twice as fast as the record Google set in 2019 on its cloud. "We wanted to achieve several goals with the record attempt," said Professor Heiko Rölke of the University of...

Scientists discover why Stonehenge is so tough | Digital Trends Spanish

Stonehenge has always aroused the fascination of scientists and researchers around the world. It is one of the most iconic monuments on the planet and now professionals have discovered what has made it so resistant. A study conducted by the University of Brighton and published in the Plos One magazine, points out that the key to Stonehenge's strength lies in the geochemical composition of its rocks. According to the work, they are composed of 99.7 percent quartz crystals, a material that is very durable, as well as being resistant to erosion and weathering. It is practically indestructible. The sample for analysis was taken from stone 58, one of many stones that have been tumbled. It was subjected to conservation work in the 1950s after the discovery of a crack running through the st...

Scientists create fabric similar to Batman’s cape | Digital Trends Spanish

A group of scientists from Singapore's Nanyang Technological University (NTU) and the California Institute of Technology (Caltech) have developed a fabric that is flexible in its natural state, but can be transformed into a hard material, similarly to Batman's cape. This “chainmail” fabric has the ability to stiffen, being 25 times stiffer and resisting 50 times more than its own weight. That is why it has a certain resemblance to the fictional cape that appears in the film Batman Begins 2005. In the movie, this one can become stiffer to be used as a glider. The scientists showed how the fabric changes by holding it in the hand in its light and flexible state. But when the fabric was placed inside a plastic envelope and vacuum packed, it increased its structural stress and hardened to...

Scientists warn: Earth is getting worse at a worrying rate | Digital Trends Spanish

About 2,800 scientists have recently joined a climate emergency declaration that was originally signed by more than 11,000 specialists from 153 countries. It warns of the rapid deterioration of the health of our planet, and of an international policy that has not taken responsibility for this problem. According to experts, since 2019 there has been an unprecedented increase in weather-related disasters, including several devastating floods in South America and Southeast Asia; hurricanes in the Atlantic, cyclones in South Asia and Africa, heat waves and wildfires in the United States and Australia. "There is growing evidence that we are approaching or have already crossed tipping points associated with critical parts of the Earth system, including the West Antarctic and Greenland ice sh...

Climate Scientists Concerned About Space Tourism | Digital Trends Spanish

While the recent space trips of millionaires Richard Branson and Jeff Bezos have been highlighted, climate scientists are concerned about this situation. They are concerned about the growing increase in space tourism and about the stage that both entrepreneurs have just inaugurated, particularly about the effects that this trend could have on the health of the planet. Professionals fear that the increasing number of rocket flights and the increase in space tourism could damage Earth's atmosphere and contribute to climate change. According to Dallas Kasaboski, an analyst at space consultancy Northern Sky Research, a single Virgin Galactic suborbital flight lasting an hour and a half can generate as much pollution as a 10-hour transatlantic flight. This is concerning to researchers, espec...

Chilean scientists propose a new state of matter | Digital Trends Spanish

A team of researchers from the FCFM Department of Physics of the University of Chile and the Millennium Institute of Optics MIRO has managed to generate the conditions to create an exotic state of matter. It should be remembered that this state had already been observed in extreme conditions of temperature and pressure. An example of this would be superconductivity and superfluidity. Scientists have been happy about the finding and expectant about the possibilities it may mean in the future. "We are at the beginning of something that could be completely different from what we have seen," explains Marcel Clerc, professor at the University of Chile and leader of the research. "What we demonstrated was that topological transitions, that is, certain deformations that transform one thi...

Mysterious radio signal traced inside our galaxy | Digital Trends Spanish

An international team of scientists managed to track down mysterious and intense bursts of radio energy that could come from inside the Milky Way. These Fast Radio Bursts (fast radio pulses or FRB), usually last only a fraction of a second, but can be a hundred million times more powerful than the Sun, according to the researchers. They used telescopes and technology from different countries, including Canada, the United States, and China to carry out their observations. They recently reported the detection of an FRB originating 30,000 light-years away in the northern Milky Way. This would be the first FRB detected within our own galaxy. According to astronomers, it would originate from a highly magnetized object, known as a magnetar (stars with a very powerful magnetic field). "W...
