NASA Artemis mission cleared for takeoff.

According to the plan, it will take place on August 29. All checks have been completed and the rocket that will return humanity to the moon is ready for its first flight. Within its framework, all systems will be checked in combat mode. True, so far without people on board.

A material with a real three-hour memory has been discovered.

By materials with a "memory" function, they usually mean those that remember what shape they kept before exposure. But vanadium dioxide (VO2) has gone further - it can remember more than just one state. He remembers as many states as he wants for the past 3 hours. That is, it can be bent, heated, twisted, and it will remember not the last transformation, but the entire chain.

Scientists have created wind turbine blades that can be recycled into gummy bears.

American scientists have combined fiberglass with synthetic and vegetable polymers and obtained a composite resin for wind turbine blades, which can be processed into similar devices or gummy bears. Sweets can be made from purified potassium lactate - it remains after the resin is boiled down in an alkaline solution. In addition, the alkaline breakdown of the resin releases the acrylic material PMMA - organic glass, from which car headlights are also made. The new resin will help get rid of waste, since ordinary blades are simply thrown into the landfill - they are often not recyclable.

Chemists from South Korea have created an analogue of meat from sugar and proteins extracted from flour beetle larvae.

These insects are fed to small animals. The new meat substitute tastes and smells almost indistinguishable from the natural product - the sugar-treated and fried larvae enhanced the meat flavor. Scientists hope that their technology will make the production of meat and meat sauces more environmentally friendly and cheaper.

NASA has launched a service that allows you to hear how your voice would sound on Mars.

If you were standing and talking on Mars, you would hear a quieter and more subdued version of your voice, and you would have to wait a little longer to hear it. Just follow the link, turn on the microphone and record a welcome message. After a few seconds, the system will process and produce a version of your voice with a "Martian effect".

The first robotic health food restaurant.

From day to day, the first robotic healthy food restaurant will open in San Francisco, which works without any human intervention at all. What it looks like: A customer enters a restaurant and uses the touch screen to place an order. Then the robots take the order out of the freezer, put it on paper plates, heat it up and serve it to the client. Such a restaurant can process 75 orders per hour, and in total 65,000 different combinations of dishes are available in it - food can be assembled according to your requests.

Ford has created smart headlights that project useful information.

The new headlights can project directions, speed limits, or weather information onto the road so the driver can only focus on the road. Also, the new headlights will be able to synchronize with satellite navigation and security systems for the correct display of information. For example, headlights will be able to show a snowflake on the pavement, warning of an icy road. The new technology is currently being tested. Ford does not specify when exactly it will become serial.

Fujitsu will start selling the first commercial quantum computers in 2023.

So far, we are talking about medical institutions and research centers. But a couple more years, and quantum computers will be available to everyone.

Scientists have discovered new properties of the vision of flies.

They are confirmed to be able to easily dodge blows due to the special structure of their eyes. Unlike humans, the eyes of flies can distinguish not 60, but about 250 flashes of light per second. But the lion's share of evasiveness comes from the hairs - they are able to feel changes in air currents. Therefore, even turning off the light does not help and it is best to use traps.

Dubai mega project.

In Dubai, they propose to build a circular mega-structure around the tallest Burj Khalifa skyscraper to date. According to the visualizations provided with the description, the ring with a circumference of about 3 km will be supported by four towers 550 meters high. This mega-structure is planned to accommodate various types of offices and housing.

Japanese scientists have found that when meeting with the owner after a long separation, dogs cry with joy.

Veterinarians spoke about the study in the journal Current Biology. The volume of lacrimal fluid was measured before and after meeting with the owner. The conclusion turned out to be unequivocal - dogs really cry with joy.

China has created an artificial neuron of the human brain.

A neuron was created from a graphene sensor and carbon tubes, capable of both receiving and sending dopamine signals. We are one step closer to full-fledged simulations of brain activity.

British hospitals are testing smart glasses - they scan the patient and make an appointment with the doctor.

In two regions of the UK, nurses have begun testing thermal smart glasses. They scan the patient, assess the condition of his wounds and make an appointment with the doctor. Video consultations can be sent in real time to a highly specialized specialist. The glasses are able to execute voice commands, lay the best route to the patient's home and make mailing lists. The smart gadget should save the time of family doctors and make the work of nurses easier - they spend half a day solely on filling out documents and working at a computer.

Church of worshipers of hallucinogenic mushrooms sued the police for the confiscation of drugs.

Zide Door is a branch of the Ambrosia Church that advocates "safe access" to naturally occurring psychoactive substances for "direct communication with God". Zide Door has 60 thousand parishioners. They donate five dollars a month to the church and make contributions to its fund in exchange for the "sacrament" - the use of cannabis and mushrooms. In the police lawsuit, Zide Door cites the Religious Freedom Restoration Act of 1993. He allowed some US religious groups to use drugs for ritual purposes.

Singapore lifts ban on same-sex sex.

Prime Minister Lee Hsien Loong said decriminalizing homosexuality would help bring the country's regulations in line with modern social norms. The politician believes that the majority of the population will support the amendment. At the same time, he promised to defend the definition of marriage as “the union between a man and a woman”, since in many ways Singapore remains a traditional society.

Engineer James Brown has created a mini-computer out of Lego.

At first, Brown wanted to create a mechanical keyboard with screens instead of buttons. In the process, the enthusiast decided to build a computer out of Lego because he was interested in customizing tiny components in a small package. The device is powered by old 9-volt batteries and bricks with electrical contacts that Lego stopped making back in the 90s. This is enough to run the screen and the STM32 microcontroller with a 48 MHz Arm Cortex-M0 processor and 16 KB flash memory. Brown himself wrote the programs for this tiny computer, and also managed to display an image from Doom on it. The displays are hidden behind translucent Lego bricks. He spent $40 on the entire project.

Implant Keys

VivoKey has begun implanting property keys into the hands of those who wish for $400. One of the first was Brandon Dalali, who put the keys to the apartment in his left hand, and his Tesla in his right hand.

Enthusiasts took a 174-megapixel image of the moon.

Almost two years of work and finally presented the result of their hard work. The colors in the photo are real, but with increased saturation. The authors explained that red areas are rich in iron and feldspar, while blue areas indicate the presence of titanium.

In Britain, drivers will not be judged for crashes involving autopilot.

Regulators said that for this it is not even necessary to change the legislation. For all accidents at the moment when the car is on autopilot, the responsibility will be borne by the manufacturer, not the owner of the car.

A startup from Los Angeles has begun creating small houses from plastic waste.

They are cheaply processed, 3D printers are launched and with their help they create residential buildings, the price of which is several times lower than with traditional construction. For example, a small studio can be printed for $25,000.
