The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

The glaciers of the Arctic are filled with life 04.06.2023

A new study has proven that the Arctic ice is not at all as lifeless as it might seem at first glance.

It may seem that the glaciers of the Arctic are completely devoid of life, but scientists assure that this is not at all the case. In fact, the ice and snow carpets in Greenland and Iceland are literally filled with microscopic life forms.

Moreover, like seasonal zombies, many of these organisms hibernate and wake up from a frosty sleep with the onset of summer and the melting of glaciers. According to a microbiologist at the University of Aarhus in Sweden, Alexander Anesio, even in a small pool of glacier meltwater, almost 4 different species can easily be awake.

The researchers note that for the most part, these microscopic organisms thrive on bacteria, algae, viruses, and microscopic fungi. In fact, they are a whole ecosystem, the existence of which the researchers knew nothing about for a long time.

That all changed when scientists studied ice and snow on two glaciers in mid-to-late summer, one in Iceland and the other in Greenland. Most of the bacteria discovered by scientists were active, others did not move or were dead. But what was interesting was that the scientists found that a day after being thawed, some of these “dormant microbes” revived and regained the ability to read genes and produce the building blocks of amino acids. The results of the study indicate that after three days of thawing in the laboratory, the samples contained 35% more active microbes.

The data obtained by the researchers suggest that the microbial communities in snow and ice can indeed quickly respond to melting. Adapting to climate change is generally considered very beneficial, Anesio said, but it also means that a sudden change in one organism can destabilize an entire ecosystem.
