The leaves of plants are green because of the chlorophyll contained in them - a pigment necessary for photosynthesis. But why is the pigment green? What factors influenced this? Let's figure it out.
50 years ago, Roger Penrose presented the world with an idea describing a way in which extraterrestrial civilizations could receive energy from black holes. Now the scientist's theory could be proved using the achievements of the Soviet nuclear physicist Yakov Zeldovich.
The laureates of the 2019 State Prize of the Russian Federation for outstanding achievements in the field of science and technology were scientists of the S.S.Kutateladze Institute of Thermophysics of the SB RAS, Academician Mikhail Predtechensky, Academician Dmitry Markovich and Professor Vladimir Meledin. The prize was awarded for creating the foundations of the global industry of single-walled carbon nanotubes and scientific substantiation of new methods of diagnostics of nonequilibrium systems and their management.
Putting a nuclear reactor into operation takes years. The nuclear power industry branches into hundreds of directions, where each: from the separation of uranium isotopes to the choice of a coolant is a reason to defend a PhD. Is it possible to talk about simplifying technologies and increasing production rates with the help of 3D printing in one of the most difficult areas of science? American scientists say: Why not? and they offer to wait with bated breath for the world's first reactor with a 3D-printed core.
Life exists at a depth of several kilometers, in the hot and oxygen–deprived bowels of the Earth, and thrives there, completely uninterested in anything happening at our top.
Scientists at the University of Illinois at Chicago have developed a working prototype of an innovative lithium-carbon dioxide battery.
The appetite comes during the meal and then only increases. It is estimated that if the consumption of mineral resources grows at the same rate as it has been increasing since the beginning of the Industrial Revolution - about 3.4% per year - then in half a thousand years humanity will not have enough of all the reserves of the Solar System. Already today, many of the available land deposits are almost exhausted, and mining companies are looking with increasing interest at the treasures of the seabed.
In March of this year, a group of scientists from MIT managed to turn graphene into a superconductor through which electricity is transmitted without resistance. The secret is to combine two layers of nanomaterial at a magical angle.
