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...

Why do trees die in the Amazon? | Digital Trends Spanish

A study carried out by the universities of Leeds and Birmingham tried to determine the causes of death of trees in the Amazon. The results were published in Nature Communications and show that species-level growth rates are a key risk factor for tree mortality. In this regard, they realized that the fastest growing trees die at a younger age. This discovery is of great importance for understanding the future of forests, as climate change tends to "select" those species with the fastest growth. If these forests selected for climate change are more likely to die younger, they will also store less carbon. This study consists of the first large-scale analysis of the causes of death of trees in the Amazon and uses long-term records collected by the international network RAINFOR. "Under...

Brewery Gets Clean Energy By Burning Iron Powder | Digital Trends Spanish

Many industries require the burning of fossil fuels to function. Although it is an effective way, it is not very ecological. The problem is, this practice has been around for years. Fortunately, a greener way of running industries has emerged today, with much less impact on the environment. The Swinkels brewery in the Netherlands sources cheap and very fine iron powder fuel, which can burn at high temperatures, releasing energy as it oxidizes. This process does not emit carbon and produces an iron oxide, which can be collected very easily. The company has become the first in the world to use this procedure on an industrial scale. The system they have installed in conjunction with the Technical University of Eindhoven provides them with all the heat necessary for some 15 million g...

World’s First Commercial Flight Powered by Hydrogen | Digital Trends Spanish

Aircraft manufacturing company ZeroAvia successfully conducted the world's first commercial hydrogen-powered flight. It is a Piper M class six-seater aircraft, which took off from Bedfordshire in England. According to an article published in Sky News, the only thing it emits is water vapor. The British firm aims to make hydrogen planes commercially available in three years, which would mean great news for caring for the environment and a true "green" revolution in the aeronautical industry. Sky News “What we are doing is replacing fossil fuel engines with hydrogen electric motors. We also have an established fuel infrastructure that ensures the production of zero emissions of hydrogen itself, ”ZeroAvia founder and CEO Val Miftakhov told Sky News. The company also repo...

Climate study confirms worst-case scenario | Digital Trends Spanish

Global warming has caused the worst-case scenario predicted by the Intergovernmental Panel on Climate Change (IPCC), according to a study published in the journal Nature Climate Change. Led by Tom Slater of the Center for Polar Observation and Modeling at the University of Leeds, the work determined that the sea has risen 1.8 centimeters since the 90's as a result of the melting of Antarctica and Greenland. "If these rates continue, the ice sheets are expected to raise sea levels by an additional 17 cm and expose 16 million people to annual coastal flooding by the end of the century," the study house said in a press release. Supported by satellite images, the investigations revealed that the thawing of Antarctica has raised the global sea level by 7.2 millimeters, while Greenland h...
