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.

China decided to create artificial rains to save crops from drought.

The Chinese authorities decided to spray the clouds with chemicals to cause artificial rains - because of the drought in the country, rice crops, which make up 75% of the annual crop, are dying. Plants will also be treated with humectants to limit water evaporation. If artificial rain does not save the Chinese crop, inflation in the US and Europe could rise.

An Israeli startup is going to create personal clones for people for a spare set of organs.

Renewal Bio has shared plans to create realistic synthetic embryos that will be grown in artificial wombs from stem cells (without the use of sperm and eggs). Scientists have already conducted studies on mice. They placed mouse embryos in a mechanical womb and managed to grow them to such an extent that the brain began to emerge and the heart began to beat. Analyzes show that the synthetic versions are about 95% similar to normal mouse embryos, based on the mix of cell types within each.

Scientists have figured out how and when the sun will die.

Experts from the European Space Agency have analyzed new data from the Gaia Optical Space Telescope. Thanks to them, scientists were able to determine how the Sun will develop in the future. According to calculations, our star is already 4.57 billion years old, and in general it is still stable. However, eventually the star will die - the process will begin when the core runs out of hydrogen. The merger process will begin, which will turn the Sun into a red giant star and lower the surface temperature by dozens of times. In this state, it will last another thousand billion years, until it turns into a dim white dwarf. But it is unlikely that a reasonable form of life on Earth will catch this - the brightness of the Sun increases by about 10% every billion years, which entails an increase in temperature. Such changes will make our planet uninhabitable long before the end of the solar system.

Drop has released a keyboard dedicated to Tolkien's Lord of the Rings.

Especially for fans of the writer's work, a keyboard appeared on sale in Sindarin - the Elvish language and Kirt - the Dwarf language. The cost of the keyboard is $170. The device is wired and mechanical, with backlight. It connects to a computer via a USB-C interface.
