Larsen & Toubro has finished the construction of 3,800-tonne ITER cryostat — the world’s largest steel vacuum chamber and a critical part of the ITER machine — for world’s first fusion reactor as a source of endless clean energy. The company says that the final components are ready to ship to the project site in France and here is what it means for the future of humanity.
Researchers from the Peter the Great St. Petersburg Polytechnic University (SPbPU) have discovered and theoretically explained a new physical effect: amplitude of mechanical vibrations can grow without external influence. The scientific group offered their explanation on how to eliminate the Fermi-Pasta-Ulam-Tsingou paradox.
The scientists of SPbPU explained it using a simple example: to rock a swing, you have to keep pushing it. It is generally believed that it is impossible to achieve oscillatory resonance without constant external influence.
However, the scientific group of the Higher School of Theoretical Mechanics, Institute of Applied Mathematics and Mechanics SPbPU discovered a new physical phenomenon of ‘ballistic resonance,” where mechanical oscillations can be excited only due to internal thermal resources of the system.

Magnetotactic bacteria have magnetosomes with which they can sense magnetic field lines. This allows magnetotactic bacteria to swim towards North or South to find the perfect location in the deep and dark water.
What Was the Biggest Insect That Ever Lived? The largest known insect of all time was a predator resembling a dragonfly but was only distantly related to them. Its name is Meganeura.
Advanced herbicides and treatments for infection may result from the unraveling of a 50-year-old mystery by University of Queensland researchers.
The research team, led by UQ’s Professor Luke Guddat, revealed the complete three-dimensional structure of an enzyme, providing the first step in the biosynthesis of three essential amino acids —leucine, valine and isoleucine.
“This is a major scientific advance, which has been pursued globally by chemists for half a century,” Professor Guddat said.
