NASA spacecraft was able to withstand an explosion on the Sun

19.09.2023

NASA's Parker space probe made a historic discovery, becoming the first vehicle to overcome a coronal mass ejection on the Sun and confirm the existence of interactions between solar particles and interplanetary dust.

The Parker solar probe passed through one of the most powerful coronal mass ejections recorded in the history of space exploration. The device's equipment for the first time recorded the interaction between charged particles ejected by the Sun and tiny dust particles inhabiting interplanetary space.

Using the large-format WISPR camera, Parker tracked the interaction of coronal mass ejection particles and dust, analyzing changes in brightness in the images. Because dust particles scatter and reflect light, areas with high concentrations of dust particles glow more brightly. The scientists calculated the average brightness in WISPR images during orbital motion and demonstrated changes in luminosity within the coronal ejection.

Although the Parker probe completed four orbits around the Sun, changes in observations were only noted during the September 5, 2022 event. This leads scientists to believe that only powerful emissions have a significant impact on the distribution of interplanetary dust. The physical mechanism of this process is still poorly understood, but understanding it is critical for predicting space weather.

Interplanetary dust is made up of tiny particles originating from asteroids, comets and even planets, and is distributed throughout the solar system. The dim light seen on Earth some days before dawn or after sunset is the result of our planet colliding with a cloud of interplanetary dust.

Already in 2003, scientists suggested that charged solar plasma particles in coronal mass ejections interact with interplanetary dust and may even push it away from the Sun. Until now, this hypothesis has remained unconfirmed, since visible manifestations of this interaction are observed only near the Sun.

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 ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Barrier Key 30.05.2015

The nanoparticle was able to open the barrier between the circulatory system and the brain.

The blood-brain barrier does not let potentially dangerous blood components into the brain: microorganisms, toxins, immune system factors. Unfortunately, he does not miss many medicines. Physicists from the University of Montreal, led by Ani-Sophie Carret, managed to find the key to the lock that closes the barrier. They turned out to be magnetic nanoparticles. So far, experiments have been carried out on moray eels, but there is hope in the near future to move on to experiments with people.

In one of the preliminary studies, scientists found that magnetic particles can be brought to the right place using a magnetic resonance imaging device. In the new experiments, nanoparticles were brought to a barrier separating the brain and blood, and then microwave radiation was directed at them. The particles warmed up and heated everything around them, which increased the permeability of the barrier. So it became possible to drag nanoparticles with medicine through it.

The authors of the work hope that in the future it will be possible to fine-tune the technique and bring these particles that have gone beyond the barrier to the desired part of the brain. So far, this requires surgery.
