Naked mole-rat – Heterocephalus glaber

Naked mole-rat – Heterocephalus glaber – Is practically blind and has no pain. This rodent lives in East Africa. It is digging underground corridors in search of tubers and roots. For this he uses the incisors that are in front of the lips, so that the soil does not get into the mouth.
Mole-rats spend almost their entire lives underground without going to the surface. They are unusual for many reasons. Not only are they the only cold-blooded mammals, they are also resistant to cancer, aging, hypoxia and pain.
Their almost completely hairless, thick and wrinkled skin. It is insensitive to abrasions or scratches. Because Mole-rats do not have the key neurotransmitter for pain conduction (substance P).

Naked mole-rats are the longest-living rodents (they live to 30 years)

And their risk of death doesn’t increase with age. These animals have very active mechanisms repair DNA.
They also tolerate extreme hypoxia, which often occurs in narrow and stuffy underground tunnels. When there is a lack of air, mole-rats reduce life activity. They change the energy supply process (break down fructose instead of glucose). In this way they avoid brain damage.
The equally interesting is structure Social. Which resembles swarms of bees or ant colonies. Flocks of these rodents count from several dozen to 300 individuals. At the same time, only the queen and prolific male breeds. The rest are sterile and conscientiously work for the herd.

Fuel cell vehicle – Mode of action and possibilities

Fuel cell vehicle – Mode of action and possibilities of Hyundai Nexo. – So that the car can be fueled with the most ecological of fuels, hydrogen (from the exhaust pipe is extracted only steam). It must be provided with a compressed gas tank. For example, Hyundai Nexo, available on many European markets, has 156 liters of hydrogen. Which gives him a range of about 660 kilometers on one refueling.
The gas is supplied by cable to fuel cells . Where it is mixed with oxygen from the air. As a result of the reaction that followed. Electricity is produced and – as a by-product – steam. The resulting current drives the motor. Which in the case of the Nexo model generates up to 120 kW and allows a speed of 179 km / h.

Plant nutrition speed – Plants also hunters

Plant nutrition speed – And it’s not just about insectivorous representatives of the world of flora. Their victims are quanta of light, necessary for photosynthesis (the biological process of obtaining energy). The photon flux reaches the leaf at an unbelievable rate of about 300,000 km / s – and thus at the speed of light in a vacuum. To deprive him of the energy necessary for the development of the plant, he most often uses chlorophyll: the so-called chlorophyll antenna catches quanta, whose energy in a maximum of about one picosecond (10-12 seconds) is temporarily stored during the first photosynthesis reaction. At this time, the photon ceases to exist.

Ross-128b – 11 light years away from Earth

Ross-128b – The planetary system around the red dwarf Ross 128 for about 70,000 years will become our closest star neighbor.

ESI: 0,86
Size: 1,2 Earth
Mass: 1,3 Earth
Equivalent temperature: 7°C

Even closer than the GJ 273b is the Ross-128b exoplanet. It is away from us, just like a star. Which is a very quiet red dwarf, less than 11 light-years away and gradually approaching us. Based on the obtained data, astronomers have discovered that planet Ross 128b circulates around its star twenty times closer than Earth circulates the Sun. Despite such a short distance, the planet gets only 1.38 times more energy than our planet. Thanks to the cool and stable star, whose surface temperature in comparison with the sun is halved, the equivalent temperature on its surface is estimated to be from -60°C to 20°C.

Interior heating – Heat from battery or pump

Interior heating – The car’s engine can be started remotely not only in the BMW 7 Series, where the key allows you to control the car on the touch screen. But also in Swedish Volvo produced for a cool climate. Pre-heating the cabin and cooling the windows will be easier in electric cars. At Nissan Leaf, or the latest Mercedes-Benz EQC, you do not need to run the engine for this purpose. Mercedes does not take energy to ventilate directly from the battery. The Germans have used a modern heat pump to reduce energy consumption.
