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 ... >>

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Bees have emotions and mood swings
15.10.2016
Bees may experience something like happiness after receiving a treat that makes them feel more optimistic.
We usually think of emotions as internal awareness of a feeling, but there's a lot more to this subject, says Clint Perry of Queen Mary University in London. Physical changes and shifts in behavior accompany feelings of happiness and sadness.
To see if bees had similar patterns, Perry and colleagues trained 24 bees to associate certain locations and colors in the lab with cylinders of sugar or plain water. The scientists then closed the cylinders and gave half of the bees high-sugar water - the bee equivalent of chocolate - and measured the time it took for the insects to climb into the container with the hole. It was located between two closed cylinders and was painted in a medium color so that the bees would not know if there was sugar water in it or not.
The bees that received the sugar dose were quicker to get into the obscure medium feeder, as if they were more optimistic about the possibility that there was food there. And they didn't just act more actively because of the surge of energy. Both the bees that received a dose of sugar and the rest, with equal activity, climbed into the container, where there was definitely food, and with the same reluctance into the cylinder with plain water.
To see if a sugar cube could remove a negative experience, the researchers simulated a predator attack by carefully placing 35 insects in a trap that looked like a web of crab spiders. These spiders often prey on bees, but they can escape from them. Then the insects were released from the trap.
The bees given sugar flew to the feeder four times faster than those given nothing. It can be assumed that sweet food enhances positive emotions and helps to recover from negative ones - just like in humans.
After the bees were given a drug that blocks dopamine, which is responsible for the reward system in humans, all the effects of sugar virtually disappeared. This suggests that the bees behave according to their mood, Perry says.
