Geoffrey Hinton and John Hopfield, two of the main researchers in the field of artificial intelligence, won the Nobel Prize in Physics in 2024. The image was prepared using DALEE and is not a scientific image

Artificial intelligence plays a major role in two categories of the 2024 Nobel Prizes. This is a sign of things to come

It is likely that we will see more Nobel medals awarded to researchers who used AI tools. As this happens, we may find that the scientific methods honored by those Nobel Prize committees will move away from the simple categories of "physics," "chemistry," and "physiology."

Who will win the Nobel Prize in Physics this year? All predictions

The Nobel Prizes are announced at the beginning of October every year, and about a month before that rumors, predictions and speculations are spread about the identity of the candidates and the chances of winning. In recent years, using innovative data analysis tools, forecasting experts

Scientists have developed a new method of controlling quantum states using magnetic qubits

Spin-polarized currents can also be used to control the quantum states of individual electronic spins. The results of the research, published in the scientific journal Science, may be used in various technologies in the future, for example in the control of my condition

An algorithm developed by the institute's scientists heralds a leap forward in the field of humanizing antibodies and may enable the rapid, efficient and cheaper development of new drugs. The key: stability
The process of turning carbon dioxide into carbon nano fibers. From the scientific article

Two birds with one stone - turning carbon dioxide into carbon nanofibers

The idea of ​​capturing carbon dioxide or converting it to other substances in order to combat climate change is not new. However, simply storing carbon dioxide in a certain compound may lead to its leakage into the environment

Saturn's surprise: NASA discovered an energy source and a basic molecule for life on Enceladus

In the new study, evidence for additional sources of chemical energy, much stronger and more diverse than methane production, was discovered: a group of organic compounds was found that were oxidized, and this indicates many chemical pathways for the existence of potential life in the ocean

Researchers synthesized a stable C16 carbon ring, although theoretically it should have broken down immediately

Before the successful synthesis, it was not clear if it was even possible to create such a molecule and keep it stable long enough to study its structure and its electronic properties.

Using artificial intelligence to reveal magnetism

A simulation that explains the electricity production process: Acceleration secretes recycling molecules (transfers an electron) to a stainless steel electrode (the anode). From there the electrons continue to the platinum electrode (cathode) and on to the sea water molecules. Following an electrochemical reaction with the platinum, the sea water breaks down and forms hydrogen. The passage of electrons from the anode to the cathode creates an electric current, and the hydrogen emitted in the process can be stored and used later to produce additional energy in hydrogen fuel cells. Thanks to the action of photosynthesis, this process is accelerated by exposure to the sun, but it also continues in the absence of light.

Electricity from the sea

Researchers at the Technion have developed a new method for producing electricity from algae in an efficient and environmentally friendly process. The idea, born in the mind of doctoral student Yaniv Schlossberg while swimming in the sea, was developed into a prototype by researchers from three faculties
