Bioengineer finds 400-year-old yeast and recreates Latin America's oldest beer.

A barrel with a sample of yeast was kept in the city of Quito in the monastery of St. Francis, built in the 16th-17th centuries. The bioengineer found the formula for the drink in a trade magazine. Carvajal managed to brew beer only ten years after the start of the project - it was necessary to cultivate yeast and fill in the gaps in the recipe. Carvajal called his work beer and microbial archeology. He wants to make money on the old beer, but has not yet decided on the start date for the sale of the drink and its price.

Self-healing paint for cars appeared.

Scientists from South Korea have created a polymer coating that can quickly and repeatedly self-repair under the influence of infrared radiation. It is suitable for painting cars - scratches will disappear in half an hour in the sun. The new coating is more practical and better than analogues. It can be applied over regular paint. It is also suitable for smartphones and other constantly damaged devices.

Climate change exacerbates the impact of pathogens on humans.

Natural disasters exacerbate approximately 58% of human pathogenic diseases. That is, because of the climate crisis, the risk of epidemics caused by viruses, bacteria, animals, fungi is growing. American scientists came to such conclusions during the analysis of an interactive scheme demonstrating the relationship between natural disasters and 375 diseases. It turned out that 277 of them are spreading more actively due to heat, forest fires and floods. In total, scientists have found 3213 examples in history when disease outbreaks were associated with climate disasters.

The American company Embark has taught an unmanned truck to present documents to the police.

The truck detects that a car with a flashing light is following it - with a high probability this means that the police want to stop it. The drone sends a signal to a remote operator: he watches the broadcast from the cameras and decides whether to stop. After parking, the police officer can request the documents of the car, which are stored in the safe. To do this, you need to call the operator at the number written on the back of the truck and request a code. After checking the documents, the policeman can clarify the details with the operator and put the papers back in the safe. After that, the truck will return to autonomous mode and continue driving.

An unusual app for VR.

David Glowacki, a molecular physicist, has created a VR app that simulates drinking medium doses of LSD. It was tested by independent experts and confirmed that the experience acts on the human brain in the same way as a portion of hallucinogenic mushrooms or LSD.

The hologram was teleported to other countries for the first time.

For the first time, scientists have been able to conduct two-way cross-border holographic teleportation. They sent holograms of American students to the UK and Canada "without airfare." Researchers have developed Hololens mixed reality glasses, a device that resembles a VR helmet. Through lenses, a person can see not only objects in his environment, but also "virtual" objects and people. When glasses are used by several people, each of them can interact with objects that surround the other. The new technology can be applied in distance learning, space research and medicine.

The robot surgeon MIRA will work on the ISS.

The robot has been in development for almost two decades. This is the brainchild of Virtual Incision from Nebraska. The MIRA device will be tested on the ISS in 2024 to see if it is a viable medical instrument for long-duration crewed deep space missions. During testing aboard the orbital outpost, MIRA will operate in a microwave-sized experiment chamber and perform procedures that mimic those used in surgery.

A new dangerous virus in China - "Langya".

Most likely of animal origin, more than 30 people have already been infected with it. Symptoms of "Langyi" include fever, fatigue, coughing, nausea, and vomiting. Scientists have not yet found out whether it is transmitted from person to person. But they are frightened by the fact that "Langya" is similar to Nipah - one of the most dangerous viruses in the world, against which there is no cure.

Australian designer Sean Simon has created an interactive exhibition that takes you "inside the paintings".

With Unreal Engine 5, Sean created space for the gallery and installed 40 viewpoints on it, and on each of them he provided a 360 ° view. And panoramic images of the location were created using VQGAN and CLIP neural networks: they generated images for various queries, for example, “tropical palace” or “nightmare hellish view”. As a result, this is such a cool modern gallery.

My dream job.

A New York-based mattress company has opened a recruitment team that simply requires them to sleep on their products and then report back. It also requires a unique ability to sleep and the desire to sleep as much as possible. In addition to the salary, free food is also relied upon.

Would you like to invest?

Somali pirates owned an investment company for some time. You could invest in the activities of the Somali pirates and even get a share of their booty if the raid was successful.

History of Listerine

Listerine was invented as a surgical antiseptic, then as a floor cleaner, used to treat gonorrhea, and finally as a mouthwash.

The James Webb telescope captured the first ever star WR140 with incredible resolution.

The rings in the photo are streams of matter that a collapsing star in a pre-supernova state throws out during processes similar to inhalation-exhalation.

Chemists figured out how to make a liquid crystal display out of fish scales.

Japanese chemists have learned how to synthesize carbon nanoonions (CNO) from fish scales. The stable optical properties of scale nanoonions will make it possible to produce large-area flexible radiating films and LED devices. This work opens up new possibilities for the development of next-generation displays.

The drone opened the cupboard and turned the valve.

Swiss engineers taught the drone how to manipulate objects, such as opening cabinets and turning valves. It has 12 propellers that can be rotated so the drone can hover in any position. The complex manipulator was replaced with a simple stick with a hook at the end. Before starting work, the drone builds a trajectory so that the door or other object comes from the current position to the specified one. To do this, engineers hung on objects (and the drone itself) spherical infrared markers - cameras around the perimeter of the room track their position with an accuracy of tenths of a millimeter. Hypothetically, a drone can be trained to handle almost any object that can be pulled or pushed. At the same time, while it is only able to work indoors, which is equipped with a tracking system, and, for example, is not adapted to the street.

In China, they introduced a computer case with an aquarium for fish.

MetalFish has released the Y2 Fish Tank Chassis - and its name speaks for itself. The capacity of the built-in aquarium was 13 liters - this is about half the volume of the body. The kit comes with a filter, a pump and an oxygenator for aeration, which is powered by a USB connector. The manufacturer claims that you can install a Micro-ATX or Mini-ITX board, a video card up to 220 mm in size and a small power supply into the case.

A new species of giant jellyfish has been found off the coast of Papua New Guinea.

Diver Dorian Borcherds photographed a giant translucent jellyfish. Marine biologist Lisa-Anne Gershwin carefully examined the recording and came to the conclusion that it contained a previously unknown species. The discovered jellyfish was described as teardrop-shaped with a pattern on the sides. She is the size of a soccer ball. The new species is similar to the jellyfish Chirodectes maculatus, which was seen in 1997 off the Great Barrier Reef off the coast of Australia. Researchers then captured and studied the animal.

AI discovered alternative physics without human intervention.

A team from Columbia University showed the trained artificial intelligence a set of frames representing typical physical actions - burning, rotating, etc. And then, the algorithm was asked to describe this case with formulas. The AI has successfully completed the task - its formulas are working. But these are generally other formulas that are in no way connected with current physics. There is no breakthrough knowledge for our physics.

In China, a national relic, the Pingnan Wan'an Bridge in the city of Ningde, burned down.

The bridge has over 900 years of history. After a fire, it cannot be restored.

Scientists have discovered episodic memory in dolphins

They conducted an experiment and offered eight dolphins a game - people stood along the edges of the round pool, but only one of them had the ball in their hands. The animals had to swim up to the right person on the first attempt and ask him for a toy. The experiment was carried out for two days. All eight dolphins successfully answered the question "where?", and only one of them did not cope with the question "who?". So the animals demonstrated that they not only remember the event, but also the context accompanying it.
