The Roman Space Telescope, NASA's new space telescope, crushes the famous Hubble

The Roman Space Telescope, NASA's new space telescope, crushes the famous HubbleIn 4 years, a new space telescope will appear in space, which will allow humanity to learn the secrets of the abyss of the Universe. The Hubble Space Telescope has no chance against it.

According to NASA's plan, Nancy Grace Roman Space Telescope (WFIRST) will be the successor of not only the famous and meritorious Hubble, but also Spitzer. The agency wants to show us the Universe as we have not seen it before. The devices are to be ready for flight into space around 2025. The agency has published new videos, where we can see it in all its glory and learn about its scientific goals.

For you to understand how powerful this device will be, just mention one of the most iconic images taken by the Hubble Space Telescope. It is the Hubble Ultra Deep Field, which has exposed countless galaxies in the universe, dating back several hundred million years after the Big Bang. Hubble stared at a single patch of seemingly empty sky for hundreds of hours, beginning in TECH BOY 2003. Astronomers first unveiled this tapestry of galaxies in 2004.

The Nancy Grace Roman Space Telescope will be able to capture an area of ​​the sky at least 100 times larger field of view than the Hubble telescope. Of course, with the same sharpness and at the same time. The telescope is to be 2.4 meters in diameter and will allow scientists to learn more about the mystery of dark matter. It will explore vast areas of the infrared sky, seeking answers to fundamental questions about the structure and evolution of the universe, and give us a greater understanding of the exoplanets that life may exist on.

The agency plans to launch it into space in the mid-1920s. This will be one of the Agency's most important missions following the launch of the James Webb Space Telescope this year. Building WFIRST and placing it at the L2 libation point, 1.5 million kilometers from Earth, will cost a total of approximately $ 3.2 billion.

Interestingly, another powerful telescope that will tremendously expand our knowledge of the universe will use one of the two mirrors obtained from the National Reconnaissance Bureau, operating within the framework of the American Intelligence Agency (CIA). Previously, they were to be used by the Agency in spying on strategic military installations in various countries around the world, but the program was eventually closed, and extremely precise installations were handed over to NASA.

If a few years ago the CIA decided that such mirrors for espionage observation systems are already very outdated for it, we can only imagine what futuristic technologies the American army currently has at its disposal. It is a pity that they cannot be used to build new telescopes, which, with the help of space research, are only used for espionage purposes.

The agency is currently considering how to help launch WFIRST into space. Here, two options are considered, SpaceX and the Falcon Heavy rocket or United Launch Alliance and the Delta IV Heavy rocket. Although NASA will not make the final decision in a few years, but now, looking at SpaceX's recent amazing achievements in the field of drastically reducing the cost of space missions by recycling rockets, it is likely Elon Musk's company will do this risky task.

A small chip instead of a bariatric surgery? So now we will fight obesity

A small chip instead of a bariatric surgery? So now we will fight obesityIt looks like people struggling with obesity will soon have an alternative to major surgery… much safer and easier to recover.

For some people, gastric reduction surgery has so far been the only chance to reduce weight and recover, which is why many people underwent it, although convalescence is not easy and pleasant. Patients are forced to introduce new products to their diet very slowly and carefully (which takes place in five stages), as well as be careful about the amount of food consumed, because initially one meal cannot contain more than 1/4 of a cup with a volume of WEBTOOLS news 150 ml! Moreover, the operation itself is a very serious procedure that carries many risk factors, so scientists are working on an experimental alternative that can produce similar effects in an easier way.

What? The Texas A team

When the external transmitter emits a radio frequency signal, the implant receives the radio waves causing the LED to glow. Light stimulates the nerve endings, sending information about the feeling of fullness to the brain, so the patient does not feel hungry and therefore eats less. And although modern centers already use other implants that help on the same principle, they most often resemble pacemakers, i.e. they require cables connected to a power source. This means that they are much larger than the device just presented, which does not require an external power supply. The technology has so far been successfully tested in mice, so clinical trials are only a matter of time.

The Pfizer vaccine will deal with new mutations in the SARS-CoV-2 coronavirus

The Pfizer vaccine will deal with new mutations in the SARS-CoV-2 coronavirusMost of the SARS-CoV-2 coronavirus mutations we have seen so far have had little effect on its characteristics, and what's more, we had a vaccine on the way.

Everything changed a while ago when we heard about the British strain of the coronavirus, which is likely to be more contagious. And since it appeared after the vaccination process had started, questions arose as to whether the vaccine was prepared for it. Scientists, of course, immediately began to carry out the relevant research, and as the conclusions have just published, there is no reason to worry, because the vaccine from Pfizer and BioNTech is effective in the fight against 16 different mutations of the coronavirus, including the "British". According to Reuters, the vaccine does not need to be modified Web News order to counteract a virus that appears to be more contagious than others, according to a study by researchers at Pfizer and the University of Texas.

This one was called B117 and although it appeared in Great Britain, it is now also found elsewhere in the world, such as the United States, among people who have not traveled to the UK, so its prevalence is only a matter of time. It is worth remembering, however, that there is currently no evidence that it is more dangerous than previous strains, and we have confirmation that the vaccine is just as effective against it: - We tested 16 different mutations and none of them have a significant impact on the virus. This is good news. Of course, this does not mean that 5pm will not have either, explains one of Pfizer's scientists, Phil Dormitzer.

Is this last indication just a theorizing, or is it pointing to another mutation that has gotten loud recently, namely the one in South Africa? It's hard to say, especially since local scientists have suggested that this may be more problematic, but we'll only see everything in a few weeks: 'It's just a theoretical concern, but it is justified that the South African variant may be more resilient,' Professor Shabir Madhi said at the time in a speech for BBC. At the same time, however, he pointed out that theoretically we are dealing with a different virus than the one in Great Britain, but at the same time, both have the same N501Y mutation, which is most likely responsible for the increased transmission rate, so the vaccine may be able to handle this strain without any modifications. Time will tell.

He criticized the government and disappeared. Where is the Chinese billionaire and founder of Alibaba?

He criticized the government and disappeared. Where is the Chinese billionaire and founder of Alibaba?Jack Ma disappeared from public life a while ago, and as we are just learning, he has been hard to see anywhere for over two months. Is the founder of Alibaba missing? Or is he hiding on purpose?

It all started when Jack Ma missed the November talent show he had funded himself - he was replaced by another representative of Alibaba, and a photo of the company's founder disappeared from the show. According to David Faber from CNBC, we are not dealing here with a disappearance, but only with deliberate avoidance, which is to result from the tense relations between the Chinese authorities and a WEB Engineering online news billionaire concern. Local legislators initiated proceedings in connection with Alibaba's alleged practices violating antitrust law, and moreover introduced provisions blocking the Ant Group's IPO, i.e. Jacek Ma's empire, which amounted to approx. USD 37 million (in the backstage, it is said that including the Chinese president himself).

And why this lack of sympathy? The open criticism of Ma's Chinese financial regulators at the October conference in Shanghai is certainly not without significance. The billionaire then called them a club of old people, unfit to oversee China's technological innovations that block their development. And while the billionaire may have chosen to remain hidden of his own free will, his situation reminds us of the case of another Chinese businessman who disappeared after criticizing the aforementioned regulators.

This was Ren Zhiqiang, a retired real estate mogul who disappeared in March shortly after he accused the party of failing to deal with the coronavirus pandemic and was then sentenced to 18 years behind bars. In fact, Chinese authorities have also arrested other critics of their response to the pandemic, such as law professor Xu Zhangrun and human rights lawyer Zhang Xuezhong. Xiao Jianhua, in turn, was hijacked from a Hong Kong hotel in January 2017, and authorities then detained part of his company, Tomorrow Group. Reason? Authorities have accused Xiao and other tycoons of discouraging investors from investing in the Chinese stock market. Little? Also disappeared, former Interpol boss Meng Hongwei, who dissolved into thin air on a trip from France to China in 2018 and was subsequently sentenced to 13.5 years in prison for bribery. As his wife assures, the man was innocent and anti-monopoly laws in China have long ceased to serve their original purpose and have become a tool to silence those who are unfavorable to the government. Will this be the case with Jacek Ma? Time will tell.

Astronauts ate radishes grown by themselves in a space house

Astronauts ate radishes grown by themselves in a space houseWe recently informed you that astronauts grew radishes on board the International Space Station and they will soon be used for research on Earth. In the meantime, they ate a few to see what they taste like.

Let us remind you that on board the International Space Station there is an orbital garden in which astronauts have been experimenting with the cultivation of various vegetables and fruits for several years. This is not an easy task, because the conditions of microgravity prevail there, so the physical and chemical processes are slightly different there than on the surface of our planet.

The cosmic garden is called Plant Habitat-02. The American astronaut Kate Rubins, who has been staying in a space home since October last year, is involved in overseeing it. On a daily basis, she deals with other experiments there, including DNA sequencing, the development of mRNA vaccines and genetic modifications.

In early December, Rubins boasted about the fruits, and in fact vegetables, of her hard work. The astronaut grew as many as 20 radishes. We now hear that the astronauts consumed some of them during the holidays. It turns out that radishes are just as tasty as those grown on Earth. This is great news from the point of view of the colonization of the Moon or Mars and the feeding of astronauts.

The remaining radishes, which were not eaten by the crew, were packed and frozen in Its science mobile refrigerators. In April of next year, they will return with Rubins to Earth and go to NASA laboratories, where they will be subjected to further testing. Scientists will check their taste, smell and nutritional value more closely, and compare them with a control group that was bred on Earth. Then we should find out if there are any significant differences between them that the astronauts did not notice when consuming them.

Demanding ray tracing running in the game on hardware from 30 years ago

Demanding ray tracing running in the game on hardware from 30 years agoA game enthusiast has decided to get the amazing light ray tracing effect that is new to the latest consoles and PCs, in a game that looks like Minecraft.

This technique is new in the world of games and animation. It allows us to trace light rays and the way light travels through space, reflecting off various surfaces. Thanks to this technology, we can obtain more realistic shadows, reflections and lighting in the created virtual world.

It turns out that with advanced ray tracing, you can enrich virtually any game, from all eras. This is evidenced by the Ben Carter project of Shironeko Labs. He decided to use the Super FX chip from the SNES in his processor, which he called SuperRT. He placed the Cyclone V FPGA board on the DE10-Nano FPGA board in the console.

Experiments have shown that reflexes and directional light are generated at a resolution of 200 x 160 pixels and 30 frames per second. This is unthinkable in modern games, but we're talking about hardware and a game from 30 years ago. This is a great achievement that made us think about enjoying such technologies several decades ago.

Scientists have written a unique video into the DNA of living bacteria and then recreated it

Scientists have written a unique video into the DNA of living bacteria and then recreated itScientists have proven several times in the past that one of the best and most permanent ways to save and store valuable information for mankind for thousands of years can be DNA.

Harvard University biotechnologists led by Seth Shipman have just managed to record a sequence of 5 images in the genome of a living E. coli bacterium, i.e. coliform bacteria. And not just any pictures, because they make up the famous movie called Sallie Gardner at a Gallop.

It was strictly scientific footage. It was established in 1878 and prepared fo Eadweard Muybridge only to finally settle the old dispute over whether a galloping horse has a moment when it does not touch the ground with any of its feet.

He constructed a system of 24 cameras, the shutters of which, thanks to a system of wires, were released by a running horse. This way, it was discovered that at some point the horse is not really touching the ground and appears to be levitating.

This fragment was saved in the genome of bacteria and then restored using a state-of-the-art gene editing method called CRISPR-Cas9. The team transformed every pixel of the old movie into a DNA code determined by a particular configuration of nucleotides, namely adenine, guanine, thymine and cytosine.

The scientists then used the CRISPR method to embed this sequence of information into the genome of E. coli. The works were suspended for a week and the processes taking place in the bacteria were observed. For seven days, they divided and multiplied, passing the saved frames of the film to the next generations. Ultimately, geneticists sequenced the DNA extracted from the bacteria and recreated the film. Amazingly, a whopping 90 percent of the recorded information remained intact.

This remarkable experiment shows that the genome can become an ideal carrier of valuable information that can be passed on for generations to come and become indestructible.

Scientists also want to use their method to record data such as changes in the expression of genes that affect the development of neurons and other types of cells. In this way, they could track disease development in real time and predict the occurrence of threats to human health.

We know when Virgin Orbit will launch a rocket from the plane. NASA missions will be on board

We know when Virgin Orbit will launch a rocket from the plane. NASA missions will be on boardThe company, owned by Richard Branson, the head of the Virgin group, after two years of testing, is finally looking to successfully inaugurate a new era in the space industry. Payloads will be launched into space from the Jumbo Jet.

The first presentation took place in May 2020 at Edwards Air Force Base in California. Virgin Orbit has announced that the take-off, flight and landing of the Boeing 747 Cosmic Girl and the launch of the rocket suspended from the plane were successful. Unfortunately, her flight was unsuccessful. The explosion occurred shortly after separation and starting the engine. It was a partial success for the company and its employees. The team had to work on their technology a little more.

The company has already announced another test, which is to take place on January 10. The launch windows will appear on January 17, 24 and 31. The plan assumes that during the next flight of the rocket, CubeSat microsatellites with experiments belonging to the American Space Agency will be on board. It is only a matter of time before the space industry will acquire a new and cheap form of carrying charges into the Earth's orbit.

"Our team conducted its pre-take-off and flight operations with incredible skill," said Dan Hart, CEO of Virgin Orbit. “Test flights are for obtaining data, and now we have a treasure trove of data. We have achieved many goals that we set for ourselves, although not as much as we would like. Nevertheless, we made a big step today. Our engineers are already reviewing the data. Our next rocket is waiting. We will review, adjust and start preparing for the next test which is coming soon. "

The LauncherOne rocket is powered by two engines, a single NewtonThree on the first stage and a single NewtonFour on the second stage. Both engines run on liquid oxygen and kerosene (RP-1). Modern rockets will be able to carry small payloads of up to 225 kilograms into space, but this is enough to orbit, for example, a constellation of small satellites.

Virgin Orbit plans its first commercial missions in the first quarter of this year. The company foresees great interest in this way of carrying cargo into space. There may be up to 12 launches by the end of the year, and as many as 24 in 2022. The acceleration of Richard Branson's engineering team should come as no surprise, as competition is growing in the world of the private sector of the space industry.

The Stratolaunch company, which is working on the project of the world's largest plane with the same name, has similar plans. The machine is built from two modified Boeing 747 fuselages and its task will be to carry and launch rockets with loads into Earth's orbit. The company also plans to build a hypersonic vehicle called the Talon-A. With its help, it will be able to carry out projects related to the transport of goods between global metropolises.

We haven't seen such a well-preserved Ice Age wolf yet

We haven't seen such a well-preserved Ice Age wolf yetThe found mummy of a wolf puppy lay in the permafrost for some 57,000 years to finally reveal some secrets about his life and death.

The mummified little she-wolf - in perfect condition - was discovered by people involved in gold mining in Canada in 2016, but only now have we learned the secrets it holds. “He's the most complete Ice Age wolf we've ever found. All her soft tissues, her hair, her skin, and even her tiny nose are there. It's just complete. And that's very rare, explains study author Julie Meachen of Des Moines University. The specimen underwent a number of highly detailed analyzes, including radiocarbon dating, DNA sampling, and measurements of oxygen isotope levels. Thanks to this, we know exactly when the puppy died, and we know its age at the time of death, which was only 7 weeks.

In addition to being the most complete gray wolf of the Ice Age, the puppy is also surprising where it was found in North America. Such species are much more common, for example, in Siberia, so most of the research is carried out on them, although at the same time much more difficult to extract them there, and this time we have the opportunity to get to know the ancestors of American wolves better. The researchers found that the mitochondrial genome carried in the maternal line is similar to the wolves of both Russian and Beringia, i.e. the vegetated belt of land that exists during the ice age and connects today's Siberia with northern Canada and Alaska.

Such a well-preserved specimen also allowed researchers to better understand the diet of the wolves of that time, although interestingly, ultimately it was the bones, not the 57,000-year-old intestines, that revealed these secrets. In its short life, a puppy has mostly eaten food that lives in the water, such as Chinook salmon, which is also found in modern wolves, who are able to change their diet seasonally to fish during their stay in Alaska. However, scientists assumed rather that the Yukon wolves fed mainly on buffalo and Arctic musk oxen during the Ice Age. It cannot be denied that researchers were very interested in another fact - why the puppy is so well preserved and why he was alone at the time of death. One theory is that the cavity must have collapsed, so the body immediately had ideal conditions for mummification - cold, dry, and out of air. So why wasn't the rest of the herd there when a puppy of that age was certainly not left without siblings or mothers? Perhaps they have left the lair, but unfortunately it will not be possible to establish this. However, we can count on the fact that as global warming progresses, it will find more such relics of the past.

The new hypercars accelerate to 530 km / h. Braking looks like a volcanic eruption

The new hypercars accelerate to 530 km / h. Braking looks like a volcanic eruptionNot so long ago, hypercars barely exceeded 400 km / h, and today they can easily reach 530 km / h. Braking from such enormous speeds puts a heavy strain on the braking system.

Bugatti recently announced that it has created the world's first solid piece of titanium brake caliper using a 3D printer. Now we can see how the disc and caliper heat up when braking from just 380 km / h. We are just writing because the 1750 hp SSC Tuatara braking system must withstand speeds of over 500 km / h.

During the latest experiments, the disc was accelerated on the bench to a speed of 380 km / h and the brakes were applied several times. The effect is spectacular and vividly shows how incredible loads the braking system of the hypercar experiences during high-speed driving.

Already during the third braking, the temperature of the discs and the caliper weighing 3 kilograms exceeded 1000 degrees Celsius, and during the race on the track, acceleration above 300 km / h and braking to 100-150 km / h takes place tens or hundreds of times. Despite this fact, the titanium calipers from the 3D printer perform excellently, so we can expect to see such a brake system in the company's new models.
