American scientists have perfected the fastest camera in the world in order to capture transparent objects and invisible processes such as shock waves or laser pulses. The description is given in the journal Science Advances. The Caltech scientific team has manufactured a camera that literally captures the invisible, at a billion frames per second

Scientists continue to push the limits of what cameras are capable of.

As a newly developed ultrafast photography device (pCUP), it is capable of capturing an impressive billion frames per second.

That’s amazing, but it’s not a record, because some of the same researchers developed a camera that can take 10 billion shots per second in 2018.

However, this new camera also has another party trick: it can capture transparent objects and other invisible phenomena with the naked eye, such as shock waves.

While this incredible technology will not be very useful for your holiday photos or Instagram selfies, it promises to have a variety of scientific uses in physics, biology and chemistry.

The camera works using the innovative technique used in the 2018 model, where measurements of light intensity are combined with a static image and some advanced mathematics to produce all those frames.

New this time is an additional ingredient, phase contrast microscopy: this is an older photographic technique in which changes in the relative positions of light waves as they pass through different densities become changes in the bright.

“What we have done is to adapt standard phase contrast microscopy to provide very fast images.”

“This allows us to obtain images of ultrafast phenomena in transparent materials,” says electrical engineer Lihong Wang of the California Institute of Technology (Caltech).

Phase contrast microscopy was invented by Dutch physicist Frits Zernike in the 1930s, and clings to the way light changes speed as it passes through the materials.

These changes in speed make materials such as glass much easier to detect with this technique.

As for the newest part of the technology, the Caltech team calls it ultrafast compressed lossless coding technology (LLE-CUP).

This marks the next generation of Streak cameras, devices that capture an entire event at once in a way that allows the time of light waves to be recorded.

Wang’s previous work added a new component, a load-coupled device, which reduced the times.

Now, he has combined an improved form of this configuration with microscopy that filters out the scattered light to map the changes that the human eye cannot see.

With increasingly sophisticated scientific cameras, they are leading to new discoveries about the world around us, whether to take snapshots of the human body or to record quantum entanglements.

Here, the researchers successfully captured the movement of a shock wave through water and a laser pulse through a crystalline material.

According to the researchers, their camera could be used for more purposes in the future, as it can be combined with several other existing optical imaging systems.

It could, for example, eventually allow scientists to capture the way flames expand in combustion chambers, or record the signals that travel through neurons on a microscopic scale.

“As the signals travel through the neurons, there is a tiny dilation of the nerve fibers that we hope to see,” says Wang.

“If we have a network of neurons, maybe we can see their communication in real time,” he concluded.

Cyberfarm 2077. YouTuber showed what a Russian cyber village could look like

On November 19, the day the Cyberpunk 2077 video game was supposed to be released, a five-minute video about a Russian cyber village appeared on YouTube. It combines the aesthetics of cyberpunk with the life of the Russian provinces.

Russian director and blogger Sergei Vasiliev made a short film that is an excerpt from the life of a fictional Russian village with the technologies of the future. The short film was shot in the style of a video blog. 

“They say that Russia is a technically backward country, there are no roads, no robotics, rockets do not fly, and mail takes too long. [This is not true],” the creators say.

The main character, a farmer called Nikolai, talks about his cyber farm, where three androids work, and invites new workers to his business. The robots milk the cows, walk them and go to fetch water. Instead of a cesspool, there is a black hole in the toilets, and mail is delivered by flying wagons of the Russian Post. New technologies have also solved the problem of Russian roads – cars now fly over it, but even there are holes in the air.

The authors of the short film said that a “creative association of enthusiasts” worked on the creative, and now they “plan to release further videos in the same universe.”

German scientists have found a drink that kills coronavirus in five minutes

German scientists have found a drink that kills coronavirus in five minutes 95

German scientists from the University of Ulm have discovered a natural product that kills up to 97% of the coronavirus in the body. The researchers published their work in the journal bioRxiv.  

During the study, experts mixed juices with viruses at room temperature and monitored the results. It turned out that black chokeberry juice most effectively suppresses the activity of the virus in the human body – it destroys up to 97% of COVID-19 pathogens in just five minutes.

In addition, pomegranate juice can kill up to 80% of the coronavirus pathogens. The rest of natural juices and green tea can also weaken the disease, since they have an acidic environment and plant polyphenols that negatively affect the virus.

In order to get rid of 80% of COVID-19 pathogens, scientists recommended that patients rinse the oropharynx with these solutions and rinse the nasopharynx. The study adds that plant polyphenols and acidic environments have a damaging effect on viral proteins.

During the study, scientists mixed drinks with viral particles and influenza A virus (IAV), adenovirus 5 (AdV5) and SARS-CoV-2. The observation was carried out under room temperature conditions. The experts also worked on swine flu with different juices and teas.

“Preventing the initial infection or reducing the viral load of an infection can relieve symptoms, prevent spread to the lower respiratory tract or transmission to another person,” the study said.

Netflix sci-fi show about life on other planets kicks off in December

Netflix sci-fi show about life on other planets kicks off in December 96

In early December, Netflix is ​​launching a new show, Alien Worlds, dedicated to alien planets and the life that might have developed on them.

The show’s creators relied on real facts and astrobiology to imagine creatures that could inhabit the exoplanets that support life in our modern sense.

Naturally, all this is nothing more than speculation. We do not have the opportunity to send missions to these worlds, and even if we build an apparatus for flying to neighboring systems, the journey will take hundreds of years. 

Therefore, scientists are counting on a new generation of telescopes and analysis systems to determine the composition of the atmosphere of exoplanets. Next year, the launch of the James Webb Telescope will take place, which will allow you to look deeper into space. 

Alien Worlds premieres on December 2.
