Best of Press: Science and Technology News # 12

Every month, we scan the French and international press to offer you a selection of the most necessary, fun, amazing or simply very useful scientific and technical information!

Here you will find a summary of our scientific and technical news that turned upside down or turned upside down this May. And as usual in our “Best of Press”, you will find bonus information at the bottom of this article!

Climate rediscovery?

Thirteen final research teams for the European Innovation Award 2022 have been announced since Tuesday, May 17th. Through Sciences at Avenue, AFP tells us that eight of the finalists are women and seven of the thirteen projects are related to energy and climate change. According to the European Patent Office EPO, an international jury will award the four teams on June 21, awarding them “their contribution to technology, sustainability and economic growth as well as improvement in daily life”.
French aeronautical engineer Frederick Pasternak is running an interferometer, a satellite meteorological instrument that will significantly improve the accuracy of weather forecasts and scientific predictions on climate change. It lists the gases in the atmosphere (CO2, CH4 and other chemical compounds), determines their quantity and identifies them very precisely.
Also in France, chemist Claude Grisson has developed a method for contaminating contaminated soil by absorbing metals through plants, for example in the vicinity of mining sites. After their harvest, they can be used as “eco-catalysts” (filters) to create new molecules for the chemical, pharmaceutical and cosmetic industries.
Check out the June 21 EPO website to learn about the other eleven finalists and the results!

What makes the moon shine?

Sunday 15th May to Monday 16th May night, Moon, Earth and Sun. Absolutely Aligned. This one led Full lunar eclipse. Earth, casting its shadow over the moon, loses its white hue and takes on a tan color.
The phenomenon of the sky was visible from parts of the European, American and African continents between the moonrise and the crescent. The photos, sometimes spectacular, spread on the web on the morning of May 16 ৷ Is the event Show again Thanks to NASA. With a little patience, the next listing can be enjoyed live in November 2022!

Immersion in an underground world

On May 6, Chen Lexin, his expedition team, and Guhara explored a huge new karst sinkhole in Lei County, southern China. It’s the 30th date “Tiankeng”, a Mandarin word that can be translated as “heavenly hole” Of this region. Their formation results in the dissolution of rocks by rainwater. They flow through the cracks, gradually widening them. This results in huge chasms.
To explore this valley, the expedition descends to a depth of 192 meters. It is 306 meters long and 150 meters wide for an area of ​​more than 5 million cubic meters. Zhang Yuanhai, a senior engineer at the China Institute of Karst Geology, described the depth of the sinkhole as “another world.” It opens the entrances to three caves, and has a forest with trees 40 meters high, as described by Chen Lixin. Dense undergrowth that lines the soil “as high as a person’s shoulder”. He added: “I would not be surprised to learn that species have been found in these caves that have not yet been reported or described by science.” Here is something to inspire our dreams as readers of the former Jules Verne.

There is water in the ice

An American scientific team has discovered a huge reservoir of liquid water hidden under an ice cap in Antarctica. The study was published in the May 5 issue of the journal Science. This could change the evolutionary forecast for this region of the world.
The expedition took the team to West Antarctica, 700 kilometers from the South Pole, in the Huilans Ice River, as it infiltrates with liquid freshwater.
This discovery calls into question the knowledge of the organization of the layers of Antarctica. According to him, at the top was fresh water in the form of ice. It rests on a layer of silt, which rests on a deep rock foundation. The water flowing between the upper and lower layers has not yet been studied.
The team employs magnetoteluric imaging techniques, explained Chloe Gustafson, a post-doctoral fellow in oceanography at the Scripps Institute at the University of California, San Diego (UCSD): “It analyzes the electromagnetic fields generated by the sun, but also by the earth. Ice, sediment, bedrock, freshwater or saltwater all have different signatures. It’s a lot like an MRI of the earth.”
The data collected revealed the amount of groundwater in sedimentary basins more than one kilometer thick. The salinity samples suggest a deep exchange between the fossil seawater and the current molten water above. More results to follow …

regoliths joy

A study has been published Nature Communication Biology This May 12 tells us that for the first time, scientists have succeeded in growing plants on the moon. NASA chief Bill Nelson explained That “this study is critical to NASA’s long-term human exploration goals.” He added: “We need to use the resources on the moon and Mars to develop deep space food sources for future astronauts.”
This test does not follow a new trip from Earth to the Moon. Researchers at the University of Florida have made several experiments for this experiment Samples were recovered during Apollo 11, 12 and 17 missions. These 12 grams were collected from different places on the moon. They are made up of regoliths, rocks that they cover the surface.
Two days later, Arabidopsis gives Thaliana seed sprouts. This plant was chosen for easy cultivation especially in adverse environment.
Astronomer Anna-Lisa Paul runs the lab Space Plants Lab, Who send planters to the International Space Station to control their growth. He is the lead author of the study, and reports that twenty days later, scientists collected them specifically for their DNA study. Lunar plants react similarly to adverse environments, such as if the soil contains too much salt or heavy metals. They will work to understand how to make this environment more hospitable.

Bonus: Listen to a black hole

NASA took advantage of its Black Hole Week from May 2 to 6, 2022, to publish a video translating the word black hole from the star Perseus. Located more than 200 million light-years from Earth, the constellation discovered in 2003 is made up of thousands of galaxies covered in hot gas. The interior of Perseus emits pressure waves, which propagate through all the surrounding hot gases. This allows the sound waves to translate from the black hole to its surroundings. This note is inaudible to the human ear because it is about 57 octaves below the middle C. Lunar X-ray space observatory has the frequency of this wave Billions of times. Here are the results. The image in the video is also a capture of the moon.
And we said silent place!
