Goodbye Wi-Fi, hello Li-Fi.

The IEEE has adopted a new standard for wireless data transmission. Instead of radio waves, visible light waves will act as a transmission medium, and an ordinary LED light bulb can serve as a transmitter. Most importantly, the speed of such a network is 100 times faster than regular Wi-Fi. But there is one significant disadvantage: the light cannot go around walls and other opaque obstacles.

China has successfully launched a methane rocket for the first time in history.

The private company Landspace launched ZhuQue 2, and it became the world's first methane carrier to reach orbit. Thus, the Chinese are ahead of NASA, Roskosmos, and SpaceX.

The James Webb telescope has recorded the brightest explosion in space.

Such flashes are called "kilon" - these are the most powerful cosmic explosions that occur when two neutron stars collide. During such a flash, as much light is released as 1 billion stars the size of the Sun could produce in the same time.

A rare natural phenomenon.

Residents of the Indian city of Haridwar observed an unusual and impressive natural phenomenon - a shelf cloud.

A place called Club-Q has opened in Tokyo where men pay to be beaten by girls. The institution is fully compliant with the law. For 45 minutes of strange "pleasures" they ask for $ 200.

Scientists have proposed protecting Tibetan glaciers with a reflective film.

The Dagu glacier, where the experiments took place, has lost 70% of its mass over the past 50 years. At the same time, it provides drinking water and electricity to the inhabitants of the Tibetan Plateau. The researchers hope that a film made of cellulose acetate, a natural fiber from plants, will help slow the warming. In hard-to-reach places, the substance can also be sprayed using drones. The experiment will last from three to five years. During this time, scientists will collect water samples to study the impact of the coating on the environment.

In the US, they came up with a fire-resistant bioplastic from algae.

Researchers from the University of Washington powdered spirulina and got a pure miracle material that does not burn and decomposes in a compost pit faster than a banana peel.

The scientist lost a box of wine to the philosopher after a 25-year dispute.

In 1998, neuroscientist Christoph Koch and philosopher David Chalmers argued that within the next 25 years, science would find signs of consciousness in human neurons. After a quarter of a century of research, the neuroscientist conceded defeat and presented David with a bottle of 1978 Madeira on stage.

Little surfer seal.

San Diego has a new attraction - a little surfer seal named Sammy. A baby seal jumps on the boards and rides the waves with a buzz. Sammy not only "lies" on the board, but also imitates the movements of athletes.

OpenAI is forming a team to keep "superintelligent" AIs in check.

OpenAI is forming a team to keep "superintelligent" AIs in check. The company believes that AI with superior intelligence could emerge within a decade. The Superalignment team will seek to solve the main technical problems associated with the management of superintelligent artificial intelligence - for this, it plans to develop and train special AI, the purpose of which will be to assess the security of other AI systems.

Drones pick apples in Israel.

The drone is able to determine the degree of ripeness of apples, the level of sugar content, whether they have any diseases or worms. The farm also has machines that pollinate apple blossoms instead of insects and determine the best time to do so.

In San Francisco, a confrontation between people and unmanned vehicles began.

The main tool of struggle is an ordinary traffic cone. They put him on the hood and run away, breaking the logic of the autopilot.

Soil improvement could save the planet from catastrophic warming.

A new study has found that small improvements to agricultural soils around the world will help fight climate change and keep global warming below 1.5°C. Farming practices that increase fertility and yields in the long run can store carbon in the soil, but they are often ignored with large amounts of artificial fertilizers. Green farming practices could reduce carbon emissions by 31 gigatonnes per year, according to new calculations. This value is enough to avoid catastrophic warming in the coming years.

Even a turned off phone on the table interferes with work.

Smartphones make it difficult to concentrate on work, even if they are turned off, but are within sight. These conclusions were made by scientists from the University of Paderborn during a study involving 42 people aged 20-34 years. The effect can be explained by the fact that even during work, people involuntarily glance at the phone. Because of this, the brain has to suppress the desire to turn on the gadget in order, for example, to read messages. This process takes away cognitive resources. Specifically, working memory.

Scientists have determined the maximum temperature suitable for human life.

British biologists have followed the changes in metabolism in humans at high temperature and humidity. It turned out that constant heat at 40 ° C leads to a sharp acceleration of metabolism.

In Japan, gardeners brought out the "lemon melon".

It took the horticultural company Suntory Flowers in Hokkaido five long years to grow the unique fruit. Those who have tried lemon-flavored melon say that it is very refreshing and is “the perfect fruit for summer.”
