New materials can convert sulfur dioxide from toxic gases to useful products

Published

on

Researchers have shown that thanks to new materials composed of specific polymers, harmful sulfur dioxide can be “trapped” and turned into useful compounds. This system can reduce sulfur dioxide emissions by selectively trapping contaminant molecules in a specially designed “cage.”

This trapped gas must not be stored, but can be used for various industrial processes and various types of products after conversion. The material is made up of porous molecules, also known as organic molecular structures (MOFs), inside which are spaces that function as cages. Researchers have found that they can be very efficiently separated from gas mixtures at high temperatures, including the presence of water, by exposing them to lab-simulated vehicle exhaust.

According to the same researchers, this new method is much more efficient than other methods to capture sulfur dioxide. In fact, other methods disperse many solid and liquid wastes, removing up to 95% of harmful gases. Furthermore, as Gemma Smith, the lead author of this study pointed out, “The regeneration pass is very efficient in terms of energy compared to what has been reported in other studies. Sulfur is released at room temperature to convert it into a useful product, while the organometallic structure can be reused for more separation cycles.”

Sulfur dioxide pollution is caused by human activities, particularly those related to power plants, industrial activities, trains, ships and heavy machinery. This research was published in Nature Materials.

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.
