In Boston, they found a legal way to pump the brain by stimulating certain parts of it with electricity.

According to scientists, there is no risk at all - the operation is completely harmless. However, in return, both the long-term and short-term memory of the volunteers became several times stronger and better for a month.

In Texas, footprints of dinosaurs appeared at the bottom of a dry river.

In the Dinosaur Valley National Park in Texas, almost all water bodies dried up due to the heat, and new traces of ancient dinosaurs were found at the bottom of one of the rivers - no one had seen them before. They belong to the predatory Acrocanthosaurus and the herbivorous Sauroposeidon. Animals left footprints 113 million years ago. An adult Acrocanthosaurus weighed about 6.5 tons, was 4.5 meters tall and reached 11.5 meters in length. The predator lived in the Cretaceous period in what is now the United States. Sauroposeidon weighed about 44 tons and could raise its head to a height of 17-18 meters. The tracks are well preserved under the silt, but after heavy rains they will disappear under water again.

A site-constructor has appeared, where everyone can create the iPhone of their dreams.

In the web editor, you see a virtual smartphone in a "bare" form (without cutouts, ports and cameras). You can glue the Android logo, the long-missing Home button, and even a cup holder to it.

By the end of the century, it will become dangerous for people in some countries to go out because of the heat.

American scientists have calculated how the number of extremely hot days will increase over the course of a century. They built several models based on emission data and different combinations of temperature and humidity. If humanity manages to keep the level of global warming at around 2 ° C, by 2100 there will be 3-10 times more dangerously hot days in the USA, Western Europe, China and Japan. In the tropics, their number can double. In the worst case scenario, extremely dangerous heatwaves during which you cannot go outside could become the norm in India and sub-Saharan Africa. Now heat above 39.4 °C is considered dangerous, and above 51 °C is considered extremely dangerous. These are US National Weather Service estimates.

Lay's has released a "washing machine" for fingers.

A small gadget designed to clean the skin from oil residue and crumbs. "Washing Machine" was released in a limited edition, which will be drawn in a special lottery in Japan. The device will not go on sale.

In the US, naughty schoolchildren decided to beat with a shovel.

The Cassville School District in Missouri has decided to reinstate corporal punishment for students that was abolished in 2001. New disciplinary measures were proposed by the parents - they did not like the option of suspension from lessons. Flogging will be the last resort. Only the director can beat children in the presence of a witness who is not a student of the school. You can’t hit the face and head, only the buttocks. Junior students will receive 1-2 slaps, high school students - up to 3. Parents who want their children to be beaten must sign an agreement - the form will be drawn up by the school administration.

A foreign language is not forgotten over time.

Even 50 years after learning a foreign language, the level of proficiency in it remains the same. These conclusions were made by scientists from the University of York. They rounded up 500 Britons who had taken A-levels in French from 1970-2020 and gave them a second test. Volunteers from the older group did just as well as recent graduates. People remember words the same way they remember facts, dates, and names. Over time, they may begin to be forgotten, but grammar is learned once and for all - like riding a bicycle.

The James Webb telescope has sent new images of Jupiter.

The photographs show incredible quality and a high level of detail. Now you can see the smallest details: auroras, fogs and even a storm. They were made with a NIRCam camera in the infrared spectrum, which is indistinguishable to the human eye, so they were painted in post-processing.

Strangers who look alike have similar habits and DNA.

Spanish scientists have found that strangers with similar facial features have similar habits, behaviors and genotypes, while they differ in DNA methylation and microbiome. For research, scientists took pictures of Canadian photographer Francois Brunel - since 1999 he has been doing a project about twins. The scientists contacted pairs of doppelgangers, took DNA samples from them and asked them to fill out two questionnaires: biometric and lifestyle. According to the researchers, only one pair of twins out of 32 could have common ancestors. Some outwardly similar people even lived in opposite parts of the world. The results of the study can be useful for genetic diagnosis and forensic medicine - it will be possible to quickly and accurately recreate the face of a criminal from his DNA.

As part of Gamescom 2022, a new game based on the Dune universe was announced.

Dune Awakening is an open world MMO with survival elements. The game will take place on the planet Arrakis. There are still few details about the project, from the announcement it is clear that the project is being created based on the sci-fi series "Dune" by Frank Herbert. The title has already had a page on Steam.

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.
