The world is colorful

'Brushing' the walls of blood vessels

US scientists have successfully built the world's smallest type of 'garbage broom' consisting of nanotubes made of carbon atoms.

Brushes with a diameter of only one-tenth of the diameter of a hair shaft, are used to 'sweep' the tiny blood vessels that are clogged, sweeping dust for ultra-precision machine parts or painting for small measuring machines. eye level is often not visible.

Nano brushes have been ordered by many medical companies for the first production.

The sense of smell is not inferior to that of dogs

American scientists found that the sense of smell is not inferior to the sense of smell of dogs.

Because people perceive the smell not only through their nose but through their entire body thanks to a special neurological center that specializes in determining the origin of external agents.

According to scientists, whole body emotion is the unique ability of humans that no animal in nature can.

Crows are the smartest among birds

According to scientists, crows are the smartest birds in birds. On the streets of Japan, crows often park on the sides of the road waiting for the time of a red light signal, then swoop down and release nuts with hard kernels on the road surface.

When the car passes over and rolls over the hard-shelled grain, waiting for the next red light signal, the crow swoopes down to pick up the kernel and has been shelled by car drivers.

Robot has personality like human

Scientists at Korea's Intelligent Robot Research Center successfully research electronic computer programs that can make robots have a 'personality' like fun, sadness, anger, hunger, thirst, fear. , happy.

This achievement poses a new challenge for people to continue to "smart" robots or not, because someday, robots will "rebel" and claim their citizens' rights. 'like humans?

Magical toothpaste

Japanese scientists successfully fabricated toothpaste can make dentists . unemployed! Thanks to this toothpaste, cavities and cracks in teeth due to tooth decay and dental diseases can be easily recovered, painless and without complicated dental solutions.

The composition of toothpaste is very similar to tooth enamel, which can be taken directly into cracks and holes. After 3 minutes, the toothpaste is crystallized and attached to the structure of the tooth.

This toothpaste does not affect health. Only the difference between artificial enamel and natural enamel can be distinguished from a microscope.

Pin from . urine

Singapore scientists successfully built a battery from human urine, used as a small source of electricity for cheap analytical tests, single use, in the medical industry, to diagnose a lot. Different diseases, first of all diabetes.

Dr. Ki Bang Lee said that in the near future, people can easily control their own health in the context of family thanks to test kits that do not need to provide complicated energy from outside.

Nano food

A type of nano-soft drink made by Manuel Marquez-Sanchez engineer of Kraft Foods Food Company is quite unique. Customers only need to buy a certain beverage, then add nanoparticles to turn them into any kind of beverage with color, flavor and aroma as you like.

At present, the nano food market has reached 3 billion USD. By 2010, this market will reach $ 20 billion in revenue. In the not too distant future, there will be a beverage or food that can treat cardiovascular diseases in the market.

Mice are capable of singing like birds

Biological experts found that some species of rats have the ability to sing or no less than birds, but with ultrasound frequencies that human ears cannot distinguish.

To listen to rats, use a voice recorder to record their songs, then change and reduce the frequency to the extent that it can be heard with the ear like a normal sound. 'Music sheet' by 'composed' mice has very different messages.

They often sing during the mating period and say the 'personality' of their partners. In addition, combined with the song, the mouse radiates to the surroundings of all kinds of feromon to attract each other.
