A nanorobot that walks by itself

Previously, such molecules could only walk in a given direction in a straight line or in a plane. The new "walker" is able to walk 36 steps on a non-uniform surface, independently deciding where to move the "foot".

Brain-computer interface accelerated 5 times

The SSVEP system allows a person, looking at a virtual keyboard, to "write" at a speed of 50-60 characters per minute, which corresponds to an information exchange rate of 4.5-5.5 bits per second.

I want to become a bioinformatician. Where to start?

1. Read and think a lot! 2. Go to schools/conferences and talk (conferences should be good). 3. Develop thinking (see point 1) 4. Choose an interesting direction 5. Look for and come up with good puzzles.

Microbes communicate like neurons

Microbiologists have found that bacteria in biofilms can coordinate their actions by transmitting electrical potentials through ion channels, similar to nerve cells in the brain.

The success of biologists will save cells from death

If we understand what happens when cells are deprived of oxygen and nutrients, it will be possible to develop a treatment strategy that reduces the destructive effect of stroke.

Antibacterial dental implants

When bacteria get on the implant, the positive charge of quaternary ammonium salts destroys the negatively charged membrane of the bacteria and they die.

30,000 neurons in a computer

According to the head of the Blue Brain Project, this is not yet a confirmation that scientists are actually able to reconstruct the human brain, consisting of 85 billion or more neurons, but the first step.

Not all video games are equally useful

Analysis of the results of observations of the brain of gamers showed that the best way to develop our nervous system is not puzzles and games for ingenuity, but shooting games and arcades.

How neurons recover

The expression "nerve cells do not regenerate" is one of the leaders among the commonly used statements about the human brain, although its falsity has been proven for 20 years.

DNA is alive and glowing

Chemists from Switzerland have developed a revolutionary dye that allows you to "highlight" DNA molecules in living cells without disturbing their vital functions, which will allow scientists to uncover many secrets of life.

When viruses were big…

American biologists have shown that viruses are not lifeless random fragments of DNA that have become "alive" by chance, but the product of the evolution of ancient cell-like structures that have adapted to intracellular parasitism.
