Successful storage of digital information in the DNA of a living organism

Hard drives and other data storage systems store huge amounts of information today. However, like magnetic tapes or floppy disks in the past, these devices can become out of date over time and we will lose access to the data we collect on them. That is why scientists have developed a method to convert data into the DNA to record a living organism. This kind of "mass storage"will probably not become obsolete in the foreseeable future.

Seth Shipman of the University of California at San Francisco, who was not involved in the work, praised the performance of his colleagues from Columbia University, but points out that it will be a long time before such systems find practical application.

"In the meantime, Worf has found out how J'Dan transferred the secret information to the Romulans. J'Dan has to be treated with hypodermic syringes for his Balthasar syndrome. When he examined the syringe, however, he found that it was an optical one Contains a chip reader that has been specially designed to
to read the isolinear chips of Starfleet. Digital information is extracted and then encoded in the form of amino acid sequences. "

Star Trek Today: Transparent aluminum (aluminum oxynitride) - from Star Trek to reality

Since the fourth Star TrekFilm came out in 1986, materials scientists have wondered if transparent aluminum could really be made. Research over the past few years suggests that we may not have to wait until the 23rd century to accomplish a similar feat.

In the more than 50 years since the first episode aired in 1966, Star Trek fans always excited to see technologies that once only existed on television have become a reality - from automatic doors to tablet computers. And although some of the most anticipated technologies, such as B. Holodecks, are not (yet) fully available, there is a technology that has emerged in recent years and that is potentially even more exciting for materials scientists.

In the Star Trek universe, the term "transparent aluminum"on a transparent metal made from elemental aluminum.

"In the meantime, McCoy and Scotty have appeared at Plexicorp. Scotty pretends to be a professor from Edinburgh and in return for a few materials that he needs for the Waltank offers the Plexicorp boss a formula for a completely new material (transparent aluminum ) l, which Plexicorp could develop and market. Dr. Nichols, the head of Plexicorp, goes into that. "

The new frontier of the universe. The most distant and oldest known galaxy has been discovered

Astronomers have found evidence of a galaxy whose light took 13,4 billion years to reach us. This is a new record that sets the current limit of the universe we know.

Philosophers and scholars have always puzzled over the beginning of time and tried to find out when everything began. It was only in the age of modern astronomy that we came close to the answer to this question. According to the most popular cosmological models, the universe began with the Big Bang, which happened about 13,8 billion years ago. But astronomers are still unsure of what the early universe looked like and call the first billion years of its existence the "dark ages". That is why they are constantly improving their scientific instruments to see even the most distant galaxies. Thanks to new research by an international team of scientists, the oldest galaxy observed to date has been identified in our universe. It is called GN-z11 bezeichnet.

They attacked a robotic vacuum cleaner and overheard what was going on in the room where it was working

Scientists from the United States and Singapore used a robotic vacuum cleaner to eavesdrop on the sound in the rooms and identify TV programs playing in the room where the vacuum cleaner was located. The performance is even more impressive as the Standalone vacuum cleaner are not equipped with a microphone. This work shows that any device with lidar technology can likely be used for eavesdropping.

We use these types of devices at home without thinking about it much. We have shown that although such devices do not have a microphone, we can rewrite their navigation system to eavesdrop on conversations and reveal confidential information, says Professor Nirupam Roy of the University of Maryland.

This in autonomous robots used Lidar system examines the environment with the help of lasers. Their light is reflected from the surroundings of the vacuum cleaner and fed into the sensors of the vacuum cleaner to create a room map. Experts have been speculating for some time that the maps created by autonomous vacuum cleaners, which are often stored in the cloud, can be used for advertising.

Space and influence on computers. The effects? e.g. wrong election result ...

On average, your computer makes a mistake every few days for no apparent reason. It is not a hacker attack, but the effect of invisible radiation that can alter the outcome of an election or lead to a plane crash.

In the Belgian federal elections in 2003, citizens voted electronically - with magnetic cards that each voter received. In the city of Schaerbeek, the unpopular candidate Maria Vindevoghel won. It would not have been exceptional if she hadn't won far more votes than there are eligible voters in her constituency. All used Magnetic cards were collected and the votes counted again. The support that the candidates received has not changed, with the exception of Mrs Vindevoghel, who this time received exactly 4096 fewer votes. A further investigation determined the cause of the error, which was referred to in the official documents as "spontaneous setting of the bit in the thirteenth position in the computer memory". To understand this mysterious explanation, one has to know how the computer stores information in its memory.

A scientist from Cracow University of Technology developed a new type of chess game - diagonal chess

Zbigniew Kokosiński, PhD, professor at the Cracow University of Technology, has developed a new way of playing the game of chess - that Diagonal chess. As read on the university website, the new game method is more interesting than traditional chess and also enables beginners to play with more experienced partners. As is so often the case, Professor Kokosiński made his discovery by accident.
 
The author of the solution checked the website The Chess Variant Pages to see that no one had come up with such an idea yet. That's how it went Diagonal chess the scientist registered it as the latest version of the game. Dr. Kokosiński works in the Automation and Information Technology Department. He learned to play chess at the age of 8. The specialist did not intend to make a revolution in the royal game. When the university introduced the obligation to work remotely due to a pandemic, it occurred to him on April 8th that chess could be played in a completely different way.
