hay variess scientific theories and speculations about how it could happen end of the world. Among the most widespread, there is the belief that the end of the world will come from the global warming and climate change. The continuous accumulation of greenhouse gases in the atmosphere could cause a drastic increase in global temperatures, changes in weather patterns, the melting of the polar caps and a rise in sea levels. These changes could have devastating effects on ecosystems and life on Earth. Along the same lines, there are those who bet on the hypothesis that the end of the…

Microplastics already flood all corners of the planet. These tiny fragments of debris, often imperceptible to the human eye, have been found from the top of Everest to the inside of the human body. There are already studies that confirm the presence of these plastics in the intestines, liver and human blood. But how do they get there and, above all, excellent are its effects? According to a study published this Tuesday in the journal 'Physics of Fluids', one of the main routes of entry of microplastics into the human body is the respiratory system. It is there where these…

We all know someone who never (or almost never) gets sick. Like those people who during the covid-19 pandemic were exposed to the virus over and over again and, even so, never got sick. This ability, which sometimes seems like a superpower, has intrigued the scientific community for years because, at least until now, it only uses a few clues to understand what could be behind this phenomenon. But what is the reason why some people get less sick than others? According to new research published this Tuesday in the journal 'Nature Communications', the answer could lie in an innate…

The Institute of Astrophysics of Andalusia (IAA-CSIC) participates in the development of a 3D global climate model of the exoplanet LP 890-9c, a way to study distant twins of venus and earth and know its evolution. Although more than 5,400 planets are known around distant starsone similar of the current challenges of science resides in detecting planets to Earth and studying their atmospheres. As the distance limits the observations, an international scientific team in which the IAA-CISC participates, based in Grenada, is developing a climate model for rocky exoplanets. this tool seeks to be able to differentiate between planets similar…
