Bees can recognize numbers

In Australia, scientists have found that honey bees can distinguish between even and odd numbers. As part of the study, the experts divided the bees into several groups. One group was taught to associate even numbers with sweet water with sugar, and odd numbers with water with quinine, which made the liquid bitter. At the same time, another group was taught the opposite associations with water. Subsequently, the scientists showed the bees cards with even and odd numbers. In 80 percent of the cases, the insects correctly determined the number. When they were shown cards they had not previously used, their accuracy rates dropped but remained at 70 percent.

The most common copper telephone wires are familiar to everyone who made the era of the early Internet. It was very slow, and until fiber came along, good internet speeds weren't available to the masses. However, scientists from Cambridge decided to test the capabilities of old copper cables. And they came to a funny conclusion - with a cheap revision, they can transfer data at gigabit speeds. And the funny thing is that, according to scientists, no one simply checked the potential of old cables - everyone simply switched to fiber optics and lost interest in improving existing lines.

Climate change and pandemics

A relationship has been found between climate change and the emergence of new pandemics that spread from animals to humans. As the Earth's climate continues to get warmer, experts believe that wildlife will be forced to move to regions with more people, drastically increasing the risk of a viral surge and could lead to the next pandemic.

Cloud seeding.

Saudi Arabia has launched a cloud seeding project over three areas to boost rainfall. The country has begun the first phase of a cloud seeding operation using chemicals. To do this, small particles of silver iodide are injected into existing clouds, around which drops of water then collect. Colliding with each other, the drops increase in size - and this, in turn, increases the likelihood of rain. With its help, the country expects to increase the amount of annual precipitation by 10-20%.

New in the treatment of Parkinson's disease

A man has been cured of Parkinson's for the first time with a brain implant. Englishman Tony Howells was able to get rid of movement disorders caused by Parkinson's disease with the help of an implanted neuroimplant. This development deeply stimulates the affected areas of the brain through electrical impulses. Previously, the patient was able to walk no more than 200 meters, but a year after the operation, he can move up to four kilometers, play golf and quickly perform daily tasks. At the moment, the device needs to maintain performance with a fairly large battery, which is located in the chest area and is connected by wires under the skin to an implant in the brain.
