Welcome to our “Science Tank” section. In this area of the website, we deal with relevant discoveries from the world of science (physics, mathematics, computer science, medicine and many more) in an interdisciplinary manner. We publish important achievements from around the world with a special focus on the scientific environment in Göttingen. Have fun and stay curious.
After the publication of our article (Medicine 4.0 on the advance), we received many inquiries on the above topic. PD Dr. Friedrich provided us with a video that we would like to present. In this pitch video, the managing director of Silent Ht Solutions GmbH the technology and the entire concept behind it. For more information, visit the company here (http://silent-ht-solutions.com/) Have fun with it!
Scientists from the International Center for Radio Astronomy Research (ICRAR) and from the University of Western Australia (UWA) have worked with specialists in the French National Center for Space Research (CNES) and the Systèmes de Référence Temps-Espace laboratory at the Paris observatory set a world record for the most stable transmission of laser light through the atmosphere.
They used innovative Australian solutions to Phase stabilization in combination with advanced optical terminals. This sent laser lightthat is not disturbed by the presence of the atmosphere. "We are able to correct turbulence in 3D, that is left-right, up-down and above all along the beam path.

The most massive are observed in the centers of large galaxies. They reach masses tens of billions of the mass of our sun. But a new study suggests that much larger black holes could exist, and in the new study, researchers at Queen Mary University London wanted to better understand black holes and limit how big they could be. In the work that appeared in the journal Monthly Notices of the Royal Astronomical Society, scientists proposed a new class of black holes - stupendously large black holes (SLABs).
SLAB
The researchers initially indicated that there was no evidence for the existence of black holes more massive than those we observe in the centers of the most massive galaxies. - We already know that black holes exist over a wide range of masses, with a supermassive black hole of four million solar masses in the center of our galaxy, "explains astronomer Bernard Carr of Queen Mary University London - although there is currently none With evidence for the existence of SLABs, it is conceivable that they could exist and be outside of galaxies, in intergalactic space, which has interesting implications for observation, he added.

For the first time it has been possible to industrially manufacture batteries that can be fully charged in just five minutes. The new one Lithium-ion battery was developed by the Israeli company StoreDot and manufactured by Eve Energy in China on standard production lines.
Replaced in the battery StoreDot the material moisture meter shows you the Graphite through solid-state nanoparticlesl, into which the ions penetrate faster and more easily. The structure of these nanoparticles is based on germanium, which is water-soluble and easy to process. Ultimately, StoreDot plans to use silicon, which is much cheaper. The company expects to prototype it later this year and claims the cost will be the same as existing ones Li-ion batteries will be.

The first clinical study to compare AI-accelerated knee MRI scans with conventional scans shows that the AI scans are not only diagnostically interchangeable with the conventional ones, but also provide higher quality images. The results of this interchangeability study are a key milestone in a joint initiative launched in 2018 by NYU Langone Health of New York City and the Facebook Artificial Intelligence Research (FAIR) group to accelerate the MRI scanning process.
The research was published in the American Journal of Roentgenology.
Spinal cord injuries usually lead to permanent disabilities such as B. Paraplegia. Research at the Ruhr University Bochum gives hope to change this. Researchers there managed to get paralyzed mice back on their feet. This turned out to be the key in applied therapy Protein hyper-interleukin-6that stimulates the nerve cells to regenerate. The way in which it was given to the animals was also important. The paralysis caused by the damage to the spinal cord is irreversible. At least that's how it has been so far, but thanks to a new therapeutic approach, scientists at the Ruhr University in Bochum, under the direction of Professor Dietmar Fischer, have succeeded in getting paralyzed mice running again.
A description of the research appeared in the journal Nature Communications

"Meanwhile, Dr. Russel reports that she invented a genetronic generator that can be used to replicate entire organs. In simulations, her success rate was quite high. Dr. Crusher does not want to allow Russel an Worf to try this technique for the first time on a real patient because the chances of success seem far too low to her."

Researchers at the University of Sussex have created animated 3D holograms that can not only be viewed from any angle, but also touched. The technology developed by the British differs from previously used holographic solutions in that it is used instead of lasers Ultrasonic used and the objects Miniature polystyrene balls be shaped.
Mars is the second planet after Earth on which the Chandler vibration was found and measured. This was done by a team from the Jet Propulsion Laboratory, the California Institute of Technology and the Belgian Royal Observatory Chandler free oscillation is the deviation of the earth's axis of rotation relative to the rigid earth's crust. In the case of the earth, the period of the Chandler oscillation is about 433 days, during which the earth's axis of rotation at the north pole moves in an irregular circle with a diameter of about 8-10 meters. The existence of such an effect was confirmed as early as 1765 by Euler predicted, and its existence was confirmed by the astronomer Seth Carlo Chandler in the late 19th century. The free oscillation after Chandler is an example of a movement that a freely rotating body that is not a sphere experiences.

Theoretical physicists at the Lawrence Berkeley National Laboratory (LBNL) believe there is evidence for the existence of Axions having found the theoretical particles that make up the dark matter consists. In your opinion it could 
Axions are the source of the high-energy X-rays that surround a specific group of neutron stars.
The existence of axions has been postulated since the 1970s. According to the hypothesis, they are supposed to arise inside stars and transform into photons under the influence of a magnetic field. They are also said to produce the dark matter, which makes up 85% of the mass of the universe and whose existence has not yet been directly proven. We can only see its gravitational influence on ordinary matter.

Researchers from China and Sweden have found that a pinch of capsaicin, a chemical compound that adds flavor to chili peppers, can be used to make more stable and efficient perovskite solar cells.
The researchers confirmed that the addition of capsaicin too Perovskite methylammonium lead triiodide (MAPbI3) led to an increase in the number of conductive electrons on the surface of the semiconductor during the manufacturing process. In other words, capsaicin made the most efficient polycrystalline solar cells at transporting electrical charge.
The research was published on January 13th in the journal Joule published.

Scientists in Japan have for the first time observed how living cells appear Magnetic fields react. Your research could prove crucial to understanding how animals, from birds to butterflies, use the Earth's magnetic field to navigate. It may also be possible to find out whether weak electromagnetic fields can affect our health.
Many animal species have the ability to Magnetoreception, so to perceive the earth's magnetic field. They use them to navigate the planet, especially long-distance hikes. However, the mechanisms behind the magnetic "sixth sense" are poorly understood. Japanese scientists from the University of Tokyo have taken a step towards a better understanding of magnetic reception. In their laboratory, they observed how living, non-genetically modified cells react to magnetic fields. The results were in the journal Proceedings of the National Academy of Sciences released. The researchers' work can help us understand how animals use magnetic fields for navigation and whether such fields can affect human health.
