Mars had a salt lake several billion years ago

Published

on

New research focuses on the existence of water in the past of Mars. According to a new study created by researchers at the Faculty of Earth Sciences at Texas A & M University, the red planet was able to rely on a number of salt lakes that were very similar to what was once found on Earth. A new study was published in Nature Geoscience.

Researchers used the analysis conducted in the Gale Crater, a rocky basin more than 150 km wide, thanks to the geological survey conducted by NASA’s exploration curiosity. Researchers concluded that the basin was once filled with salt water at least 3 billion years ago. Drying took place in connection with the same global drying process that took place on Mars, which became the desolate dry planet we see today.

This watershed should have been formed 3.6 billion years ago after the meteor hit the red planet. The crater is then filled with liquid water. However, for hundreds of millions of years, there have been many rainy and dry seasons, and many salty ponds have been formed, as confirmed by Marion Nation, one of the researchers involved.

In any case, this large crater seems to have been filled with water for a very long period, perhaps thousands of years. When the magnetic field was lost, Mars was essentially “dry” and as a result, the atmosphere was unrecoverably exposed to solar radiation. The same atmosphere fades and then disappears almost completely. This is a state in which the liquid water on the surface has almost completely evaporated.

Mars’ salty ponds had to be very similar to those found on Earth, especially in the dry highland Altiplano region located between Peru and Bolivia. In this region, the river does not reach the sea and is in a closed basin. This is similar to what probably happened to the Mars crater gale.

This type of lake is very sensitive to climate, especially humidity levels. During the driest period, the Altiplano lakes also become shallow due to evaporation and some of them dry out.

Scientists study genes regulating dog coat colours

Published

on

Studying a breed of Irish setter, a study team at UC Davis School of Veterinary Medicine discovered a new genetic element that underlies the regulation of coat color in dogs. Specifically, the researchers studied the Nova Scotia Duck Tolling Retriever, a medium-sized hunting dog, often referred to as a toller.

According to the researchers, the particular color of the coat of these dogs derives from two particular pigments, yellow (pheomelanin) and black (eumelanin). These two pigments, in turn, are regulated by the MC1R genes (melanocortin receptor 1) and the agouti signaling protein (ASIP). Depending on the mutation of MC1R, the coat of these dogs may produce more or less pheomelanin and appear more or less yellow or red.

Specifically, dogs with a larger number of copies of the DNA region on chromosome 15 have more intense coat colors while animals with a smaller number of copies have a lighter coat.

The study, which appeared in Genes, shows how much there is still to know about the different coat colours of dogs, even of other breeds. The study was carried out by senior author Danika Bannasch and graduate student Kalie Weich.

According to a famous designer, future architects will be useless due to artificial intelligence

Published

on

According to New York designer Sebastian Errazuriz, architects are among the many occupations and activities that could be literally replaced by advances in technology related to artificial intelligence. Architect and designer Elaziriz later made these statements into a series of films published on his Instagram account and later covered them in a statement.

According to ErraZuriz, it is almost impossible for an architect to compete with an artificial intelligence algorithm, and this will become a reality in the near future, so the architect himself said that “90% of the work is at risk. It is important to warn of this as soon as possible.”

In this regard, in one of the Instagram posts, the designer released an animation developed by new software that can generate building plans in a fully automated way. And this is what can happen today. Imagine this kind of technology 1000 times more powerful now.

Machine learning is becoming more and more proficient, and software can literally store large amounts of data and knowledge related to building technology in seconds. In the future, Ella Zuriz predicts that by setting various features such as budget, size, etc., getting a project in seconds will give customers more details about the type of building they want.

The same customer can “visit” the building through augmented reality technology, even before the foundation is built.

According to Elaziriz, the only architect who will survive are architects practicing architecture as an art, but that is a small elite, and at best only 1% of all architects. Everything else is doomed.

Arctic permafrost: imminent thawing more serious than previously thought

Published

on

Scientists have repeatedly mentioned the dangers associated with melting Arctic permafrost. This type of soil is a risk that stems from the fact that it is a truly massive carbon deposit that increases dramatically when released into the environment and has unpredictable effects. The amount of carbon dioxide in the air further accelerates the ongoing global warming process.

A new warning has been issued, published today at Nature Climate Change. This is a study with a decisive tone, saying that permafrost is melting more and more in the northern part of the planet, and is probably releasing much more carbon than previously calculated. The same researchers predict that CO2 emissions in the environment will increase by 17% “in moderate mitigation scenarios” until 2100.

Permafrost carbon network researchers analyzed more than 100 sites in the Arctic and estimated that permafrost released an average of 1662 teragrams of carbon in the winter of 2003-2017. This is far more than previous studies had estimated.

And due to the lack of sites considered in view of the vastness of areas where permafrost is expanding, it is still a limited study. For example, if you consider the entire Arctic, the results can be even more alarming.
