A drop of water on an asteroid? Japanese probe finds footprints in asteroid dust – Observer



A drop of water on an asteroid?  Japanese probe finds footprints in asteroid dust - Observer

The story began 8 years ago. Japan sent a probe into space in 2014 Hayabusa-2. Target? Examine the asteroid Ryugu. The plan was fulfilled, the sampling was carried out, and two years ago the space probe again entered the Earth’s orbit. At that moment, a capsule was launched with samples collected in Ryugu and which had been the object of analysis and study for many years.

Now the latest study, published in the journal Science, reveals a surprising fact: 5.4 grams of rocks and dust collected from the asteroid contained a drop of water.

“That drop of water has a lot of meaning.” During the press conference, leading scientist Tomoki Nakamura made no secret of his delight at the discovery. According to a University of Tokyo researcher, this drop of water could change our view of the origin of life. “Many scientists believe that water was brought from space, but we first detected water on Ryugu, a near-Earth asteroid.”

The drop, Nakamura explained, “was carbonated water containing salt and organics.” This is an argument in favor of those who defend the hypothesis that during collisions asteroids could bring water to Earth, with salt and organics, added the scientist, who leads a team of 150 people of different nationalities.


“We found evidence that this could be directly related, for example, to the origin of the oceans or organic matter on Earth,” Nakamura concluded.

According to Nikkei Asia, a drop of water was found in a ferrous sulfate crystal carving and is estimated to be 4.6 billion years old. Ryugu patterns will continue to be studied.

Gigantosaurus: Dino Kart, a very special kart race



Gigantosaurus: Dino Kart, a very special kart race

Outright Games recently revealed that Gigantosaurus: Dino Kart, which is in development for PC and consoles, already has a release date.

Come and find out a little more about the game and when it will be released.

British studio Outright Games, in partnership with French studio Cyber ​​Group Studios, recently revealed that Gigantosaurus: Dino Kart will release next year, 2023.

Operating Systems Cyber ​​Group Studios is the team best known for creating and developing familiar animated series such as the one that gave the game its name.

Gigantosaurus: Dino Kart is based on the hit TV series Gigantosaurus currently streaming worldwide on Disney+ and Netflix, and airing on major international channels such as Disney Junior (worldwide), France Télévisions, POP (UK) , Super RTL (Germany), RAI yoyo. (Italy), RTVE - Clan (Spain), CCTV (China), TV Azteca (Mexico) and NHK (Japan).

This series currently consists of 3 seasons of 52 episodes (about 11 minutes each) and is based on the book by Johnny Duddle published by Bonnier Books UK Ltd which has sold over 600,000 copies worldwide. The series follows the adventures of four young dinosaurs - Rocky, Bill, Tiny and Mazu - as they go on a mission to explore their world, face their fears, work together to solve problems, learn more about the mysterious Giganotosaurus along the way and, of course, get pleasure.

Along with the announcement of the game's release date, the platforms it will be available on were also revealed: Nintendo Switch, Playstation 4, Playstation 5, Xbox One, Xbox Series X, PC, and Google Stadia.

As the name suggests, Gigantosaurus: Dino Kart is a kart racing game, but it takes place in a very calm and accessible universe, making the game geared towards kids and families (just like the series released by their studios).

Dino Kart racing takes place in Cretacia in a fast paced and fun karting championship that is almost as big as the appetite of the Gigantosaurus!

Players of all ages can (and should) compete against their friends and family on original maps. Up to four players can play together in split-screen multiplayer, making the game a real family adventure.

Players can choose from eight different characters, including the famous Bill, Mazu, Rocky, and Tiny, who will speed through about fifteen tracks in various Cretan environments full of obstacles and challenges, in which the opponents themselves will also be part of the challenge.

In each race, players will be able to acquire special abilities for different purposes, and this will give them (or not) the necessary stock to win the race. For example, they can speed up the creation of short cuts during a race, or temporarily gain additional jet thrust... while staying away from the Giganotosaurus, the largest and most ferocious dinosaur on earth.

Terry Malham, CEO of Outright Games, noted that "We're so excited to be working with Cyber ​​Group Studios again on a new Gigantosaurus game - this time the iconic dinosaur vehicles are in the spotlight! We look forward to seeing players of all ages play as their favorite characters in the world of Giganotosaurus in their first kart game. We can't wait to share it with everyone next year!"

In turn, Thierry Braille, VP of Interactive and Videogame Division and Dominique Bourse, COO of Cyber ​​Group Studios, said:We're thrilled to be teaming up with our friends at Outright Games for our second game featuring Gigantosaurus and all of the series' favorite characters. We're upping the ante with this new video game that turns into a thrilling kart race!"

Gigantosaurus: Dino Kart will be released in 2023 on Nintendo Switch, Playstation 4, Playstation 5, Xbox One, Xbox Series X, PC and Google Stadia.

Earth’s twin planets in other star systems may be very rare.



Earth's twin planets in other star systems may be very rare.

It is quite possible that Earth’s twin exoplanets with proportions of land and oceans similar to our planet are extremely rare. The conclusion comes from a new study led by Tilman Spon and Dennis Hoening of the Space Science Institute and the Planetary Research Institute. They showed that worlds very similar to Earth – about 30% of their surface is covered mass continental open – may represent only 1% of the rocky exoplanets that are in the habitable zone of their stars.

The pair used the models to understand the relationship between water in the planets’ mantles and the “recycling” of continental mass as a result of plate tectonics. In general, the results showed that the observed proportion on Earth from land to sea is quite balanced, but this can easily change towards more water or more land mass if the interior of the world in question reaches a temperature similar to that of the Earth. . ground mantle1410 ºC.

Models suggest that ocean-dominated planets with less than 10% land mass will be warm and humid with tropical climates. In the case of planets dominated by land, and less than 30% of the surface is covered by oceans, the climate would be colder and drier, and great deserts and glaciers. “While all the simulated planets can be considered habitable, their fauna and flora can be quite different,” Spon added.

He explains that because we’re used to the balance between land and oceans here on Earth, it’s easy to deduce that an terrestrial planet in another star system would be very similar to ours. “But the results of our models show that this is probably not the case,” he said.

EU adopts single charger law for mobile devices – DW – 04.10.2022



EU adopts single charger law for mobile devices – DW – 04.10.2022

The European Parliament approved on Tuesday (April 10) a law that would oblige tech companies to ensure that all smartphones, tablets and cameras have the same charger in bloc countries.

The rule, which was approved in June by 27 member countries and will go into effect in 2024, is expected to have a greater impact on the Apple brand, which will be forced to replace connectors with the more common USB-C format.

For years, the American giant has fought the transition, arguing that it will lead to mountains of e-waste. However, analysts believe that this change tends to increase sales of new Apple products due to consumers being more interested in buying components with USB-C connectivity.

Electronic readers, headphones, and other devices that require recharging will also be affected. Therefore, large companies such as Samsung, Huawei and Amazon will have to adapt to the new rules.

The proposal has been discussed for years in the European Union (EU) after consumers complained about the wide variety of chargers. The European Commission estimates that a single charger will save Europeans about 250 million euros (247.3 million US dollars).

In 2019, a commission study found that about half of phones sold in the EU have a micro-B USB connector. Another 29% relied on USB-C and 21% on Apple Lightning.

Brussels believes that a standardized cable model for all devices can reduce e-waste on the continent.
