China to send monkeys into space to study reproduction

Chinese scientists plan to send monkeys to Tiangong space station for the purpose of conducting a reproductive experiment using animals. The proposal is to analyze whether they can reproduce outside the earth’s environment. This was reported by the portal South China Morning Post.

According to Zhang Lu, a researcher at the Chinese Academy of Sciences in Beijing and one of the leaders of the study, the experiment will be conducted in Wentian, the largest module on the space station, used primarily for life science experiments. The Chinese laboratory has already analyzed smaller living things such as algae, fish and snails.

“There will be some research done on mice and monkeys to see how they grow or even reproduce in space. These experiments will help improve our understanding of the body’s adaptation to microgravity and other space environments,” Zhang said.

Kehkui Kee, a professor at the Tsinghua University School of Medicine, led the orbital stem cell experiment conducted by Chinese astronauts. The complexity of a life science experiment in space increases exponentially with the size of the animals used, he says.

“The astronauts will need to feed them and deal with the waste they generate,” Key said.

negative answers

Larger animals, especially great apes, have much in common with humans, and the possibility human reproduction in space This is a question that has been questioned for decades.

Although the monkeys that will be sent into space were lab-bred and live in cages, prolonged confinement in a small space can cause some negative reactions, such as reduced activity, hair pulling, or refusal to eat. In addition, flying a rocket to a space station can also scare animals.

“On the floor, you can calm a frightened monkey with toys, song or just let them mingle with other monkeys. How to take care of them, make them happy and comfortable, will be a new challenge for astronauts,” said the expert, whose name was not disclosed.

Mice had sex in space

During the Cold War, scientists in the former Soviet Union managed to get some mice to overcome physical difficulties and have sex during an 18-day space flight. Some of the females showed signs of pregnancy, but none of them gave birth after returning to Earth.

The researchers suspected that prolonged exposure to cosmic rays, which are hundreds of times stronger in orbit than on Earth, could degrade the quality of sperm and eggs.

Some ground-based experiments have also shown that the absence of gravity can damage the testicles and some other reproductive organs, leading to a significant decrease in sex hormone levels in the animals analyzed.

couple in space

space shuttle Try, United States, took a pair of Ian Davis and Mark Lee to international space station (ISS) in 1992. But NASA says no astronaut is known to have had sex in space.

“Firstly, it is difficult to just be in close contact with each other in zero gravity. In addition, there is the problem of lack of privacy on shuttles and spacecraft, since there are no rooms in which two people can be indefinitely. alone,” said Adam Watkins, assistant professor of reproductive and developmental physiology at the University of Nottingham, UK, in a 2020 letter to Physiology News Magazine.

In any case, long-term health monitoring data collected on the ISS showed that testosterone levels dropped closer to launch or reentry, but the readings remained normal for most of the time the astronauts were in orbit.

Another NASA experiment on the ISS showed that changes in gravity and radiation had little effect on human sperm.

A black hole has swallowed a star and is spewing a jet at us

A black hole has swallowed a star and is spewing a jet at us

One Black hole it swallowed a star and fired relativistic jets at some corner of the universe far from our galaxy — enough to be the most distant black hole food astronomers have ever observed. The discovery became possible only because the jets were directed in our direction.

When a star gets too close to a black hole, a powerful gravitational force begins to tear it apart. stretching your matter like spaghetti🇧🇷 This is a one-way process. Although it has not yet passed through the event horizon (a point from which not even light can escape), the star is broken.

This event, dubbed AT2022cmc, was discovered in February this year by ZTF, an autonomous system that tracks and extracts information about unusual phenomena in the universe in visible light. Therefore, scientists sent several telescopes around the world to observe the source of radiation at other wavelengths.

Many wavelengths have been detected in the radiation released from this event, from gamma rays to radio waves, in addition to visible light itself. This was possible because the plane was directed in our direction (although without any threat), which is very rare.

The advantage of having the jet pointing towards the Earth is that in this way its brightness becomes much more intense, which allows it to be observed at different wavelengths and better calculate the distance to it. This led the team to calculate that the black hole was feeding when the universe was only a third of its current age, about 4 billion years old.

To get this result, the team needed to collect data from 21 different telescopes and compare the information to theoretical models of several types of known extreme events, such as stellar collapses and kilonova explosions.

The only scenario that explained the findings was a phenomenon called “tidal disruption,” where a black hole devours a star, stretching it like chewing gum. Other events from tidal disturbances have been observed beforebut this happened much closer to us and without jets directed in our direction.

Astronomers are constantly looking for these extreme events to better understand how these jets form, how they get so much energy, and why so little tidal disruption forms them. This is the first time an event of this type has been detected using visible light, so astronomers should invest even more in instruments like the ZTF.

This study was published in the journal Nature.

Google Chromecast atualizações software

Since the introduction of the Chromecast in 2013, it has proven its worth. It is capable of turning any TV into an internet-connected smart device with access to the content the user wants to present.

How to access new software

Updating devices is extremely simple. It usually downloads updates automatically. To manually download the latest update, follow these steps:

  • Accessing the Chromecast Home Screen with Google TV
  • Select Settings, then System, then About, then System Update.

It's great to see that Google is updating the Chromecast all the way back to the first version of the device. It won't bring much news, but it will certainly improve this offer and make it more stable and hassle-free for users.

Imagem de: CD Projekt Red quer mais lançamentos como Cyberpunk Edgerunners

after one extremely difficult startCD Projekt Red looks ok now satisfied with the results Cyberpunk 2077, especially after the release of the anime based on the series, released by Netflix. So much so that the producer intends to repeat the feat with more transmedia releases in future. Information taken from Video Games Chronicle.

This intention of the Polish company was disclosed this Monday (28) during the last meeting regarding its financial report. During the conversation it was commented how the success of Netflix animation helped boost game sales.

Launched in September Cyberpunk Edgerunners (Cyberpunk: The Expendables in Brazil) is considered the story intertwines with the game Cyberpunk 2077, which was a huge success for both the streaming platform and the Polish developer. Furthermore, animated series revived public interest in the gamewhich no longer suffered from the myriad problems revealed in its release.

Throughout the meeting, CD Projekt Red management was asked about the possibility of a second season of the popular anime🇧🇷 “We are not confirming any concrete plans for the second season of the series. Edgerunners and nothing special,” explained Michal Nowakowski, senior vice president of business development at the production company, before moving on to the interesting part of the comment.

We want to do more in the transmedia spacewhether it’s linear visual animation or live actors, and those plans haven’t changed,” Nowakowski added. “When we’re ready, you expect to see more announcements from us in this regard“, he concluded.

Taking into account not only Edgerunnerswhich revived interest in Cyberpunk 2077 e led the company to record revenue for the periodbut also games and cartoons Witcher (also on Netflix), it’s to be expected that CD Projekt Red really intends to continue with this strategy.
