Schrödinger's cat is heating up: A revolution in the concept of temperature in quantum physics

Scientists have succeeded in producing quantum superposition states even at high temperatures, breaking the myth that only cold allows quantum phenomena to exist.
If Carl Sagan were alive today, this is what he would say to US President Donald Trump, the temple of ignorance

"Carl Sagan's Prophecy: When Science Collapses Before Populism"

In his book "A World Haunted by Demons" he writes: "Immense technological power will be concentrated in so few hands that none of those who are supposed to represent the public interest will even be able to understand what things are meant to be." Isn't that

LIGO gravitational wave detectors are about to undergo an upgrade

Scientists have developed an innovative optical system designed to improve the sensitivity of the LIGO detector, the American gravitational wave detector that was a partner, along with the European Virgo, in the initial detection of gravitational waves and in many subsequent discoveries.

Murder of a physicist who destroyed an entire scientific field

Matvey Bronstein was one of the first scientists to study quantum theory. Being an expert in many fields of physics and knowing many languages ​​did not help him when he was executed in 1939 by the Soviet authorities.

The dark oxygen puzzle

Natural lumps of metal emit oxygen in the dark depths of the ocean, in the absence of photosynthesis, until now it was believed that there was no oxygen production in them at all
The competition for the preeminence in science between China and the USA, in preparation for the 2024 US presidential elections. The image was prepared using DALEE and is not a scientific image

Is the US about to lose its scientific preeminence?

A study published in Nature reveals that the US continues to lead in areas such as biomedical research, but China's continued investment in materials science, engineering and physical sciences poses a significant challenge to US dominance.

The lost atmosphere of Mars has been discovered hidden in its clay

Mars was not always the cold, desolate desert we see today. There is more and more evidence that water once flowed across the surface of the Red Planet, necessitating the existence of a thick atmosphere, but suddenly

Eil Waldman in the Science Committee of the Knesset I would like to investigate in depth whether there was improper interference that led to the cancellation of the Israel Awards

"The truth is that my candidacy was not liked by the Honorable Minister and those close to the Prime Minister and perhaps even the Prime Minister himself because I am known to be an opponent of him and the political revolution he tried to bring about," said Waldman

Declining public trust in scientists and the contribution of science to humanity in the US

This is according to a comprehensive survey published by the PEW Research Institute. The worst situation is among the voters of the Republican Party, but also among the Democrats, the majority who still show confidence in science is shrinking
This map depicts the global temperature anomalies for the meteorological summer in 2023 (June, July and August). It shows how much warmer or cooler different regions of the Earth were compared to the baseline average from 1951 to 1980: NASA Earth Observatory/Lauren Dauphin

The climate crisis delivered a strong blow: the summer of 2023 was the hottest ever

This raw data is analyzed using methods that take into account the variable distance between temperature stations around the world and the effects of urban heat islands that may distort the calculations.
