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 ... >>

Worms that eat plastic
24.03.2020
Every day we use plastic bags and throw away a lot of plastic products. This pollutes the environment so much that plastic waste has been used by animals as building materials and even eaten by them. Ecologists from all over the world are trying to come up with an effective way to clean up nature from plastic waste and from time to time offer very interesting and unusual options. For example, Canadian scientists believe that the larvae of the so-called large wax moth can effectively destroy plastic waste. It turned out that they, together with their intestinal bacteria, with great appetite eat and digest polyethylene, which has accumulated a lot on our planet.
Large wax moth larvae, also known as waxworms, are actually a problem for beekeepers. They actively feed on wax combs and destroy some of the honey collected by bees, so people try to fight them. However, in 2017, researchers found that they can be of great environmental benefit by eating polyethylene and producing the dihydric alcohol ethylene glycol as a by-product.
In the course of scientific work, Canadian scientists deliberately put the larvae on a diet consisting entirely of polyethylene. As it turned out, the worms eat plastic waste with great appetite, because within a week, 60 individuals ate a plastic fragment of a bag with an area of more than 30 square centimeters. Moreover, in the course of further work, it turned out that the larvae can also eat other materials that pollute our planet, but the researchers have not yet specified what exactly they are talking about.
Intestinal bacteria are of great help in the digestion of polyethylene by the larvae. Scientists learned about this when they compared the composition of intestinal bacteria sitting on a "plastic" diet of larvae and individuals that ate the usual beeswax. It turned out that the concentration of intestinal bacteria inside plastic waste lovers was much higher than the rest. This means that the intestinal bacteria are simply necessary for the larvae to digest polyethylene.
Even more about the importance of intestinal bacteria, scientists were convinced in the course of another experiment. They selected a few larvae and completely stripped them of their gut bacteria with antibiotics. This group ate plastic waste for a year and digestion was difficult for them. It turns out that there is synergy between the larvae and intestinal bacteria, that is, mutual assistance.
