Artificial intelligence shows that we may not even know half of the structures in our body cells

Many of the diseases that affect us are related to cell malfunction. It might be possible to treat them more effectively, but first scientists need to understand exactly how cells are built and function. By combining artificial intelligence Using microscopic and biochemical techniques, scientists at the University of California, San Diego Medical School (UCSD) have made an important step in understanding the cells of the human body.


With Microscopes we can see cell structures as small as a single micrometer. In contrast, biochemical techniques that use individual proteins make it possible to study structures the size of nanometers, i.e. 1 / 1000th of a micrometer. However, a major problem in the life sciences is completing the knowledge of what is inside the cell between the micro and nanoscale. It has been found to help with this artificial intelligence is possible.

One who rules them all. Physicists simplified the architecture of a photonic quantum computer

Modern quantum computers are very complex devices that are difficult to build, difficult to scale and require extremely low temperatures to operate. For this reason, scientists have long been interested in optical quantum computers. Photons can easily transmit information, and a photonic quantum computer could work at room temperature. The problem, however, is that while you know how to handle individual Quantum logic gates for photons, but creating a large number of gates and connecting them in such a way that complex calculations can be made is a major challenge.

However, an optical quantum computer could have a simpler architecture, argue researchers at Stanford University in Optics. They suggest a single atom with the help of a lasers to manipulate, which in turn - with the help of the phenomenon of quantum teleportation - changes the state of a photon. Such an atom can be reset and in several Quantum gates can be used so that there is no need to build different physical gates, which in turn will greatly simplify the architecture of a quantum computer.

Deformed nuclei are doubly magical. Scientists have found the missing mass of zirconium-80

Scientist of the National Superconducting Cyclotron Laboratory (NSCL) and the Facility for Rare Isotope Beams (FRIB) at Michigan State University have solved the mystery of the missing mass of zirconium-80, a puzzle they have come across themselves. The experiments carried out at the NSCL have shown that the core of Zirconium-80containing 40 protons and 40 neutrons is much lighter than it should be. The theorists at FRIB have now carried out calculations that provide answers to the question of what happens to the missing mass.

The relationship between theorists and experimental physicists is like a coordinated dance, says lead author of the paper published in Nature Physics, Alec Hamaker. Sometimes it is the theorists who lead the way and show something before experimental discovery, and sometimes it is the experimenters discover something that the theorists did not expect, adds Ryan Ringle.

Graphs in a flexible and transparent display from Poland

A team of scientists from the University of Lodz has a prototype of one OLED displays developed with a graphene electrode. The solution makes use of the plasticity and transparency of the material to create flexible, flexible screens and manufacture other types of displays.

Dr. Paweł Kowalczyk from the University of Łódź emphasizes: "It is not a theoretical model, but an actually functioning device. We have succeeded in creating a transparent structure that is compatible with OLED diodes cooperates and makes it possible to apply all solutions of flexible electronics in practice ". That used in the structure graphs was modified with rhenium oxide, which leads to better parameters of the so-called output operation, ie without unnecessary flashing of the diode.

Parker Solar Probe is closer to the sun than ever before

The probe that flies to the sun - the Parker Solar Probe (PSP) - recently broke two records. It is once again the fastest moving human-made object and the closest object to the sun. The probe is currently in the middle of its 10th close encounter with our star.

According to NASA, on November 21, the probe came at a speed of 586.864 km / h up to 8,5 million kilometers to our star. In the following rounds, PSP will continue to accelerate and get closer. The probe is gradually moving away from the Sun and between December 23rd and January 9th will send back to Earth the data it collects during its encounter with the Sun.

Electronic plasters for monitoring bones

A team of researchers from the University of Arizona developed a super-thin wireless device that works permanently with the Bone surface merges. A new electronic circuit solution of this kind, the so-called Osseo-Surface electronics, is in an in Nature Communications. published article.


The outer layers of the bone are renewed in the same way as the outer layers of the skin. So if a traditional glue was used to attach something to the bone, it would fall off after a few months. That is why the co-author of the study, John Szivek from the BIO5 Institute, developed an adhesive that Calcium molecules contains, the atomic structure of which is similar to that of bone cells. The chip is very thin - as thick as a piece of paper - so it doesn't irritate the muscle tissue that comes into contact with the bones.

Webb Space Telescope launch postponed due to an unforeseen incident

The start of the James Webb Space Telescope has delayed launch preparations by several days after an incident. The new planned start date is December 22 of this year.

The incident occurred while preparing to mount the telescope on a special adapter that connects it to a Ariane 5 missile connects. The sudden, unplanned release of the latch securing Webb to the adapter caused vibrations to pass through the telescope, reported the NASA. A press release said it happened during the works, for which the French company Arianespace is wholly responsible. The company has been tasked with launching the telescope, which will launch from French Guiana.

NASA wants a nuclear power plant on the moon

The NASA and the Idaho National Laboratory (INL) have announced that they are looking for ideas on how to access the Nuclear energy on the moon Looking for. Establishing a stable energy supply system on the moon is a key element for manned space exploration. That is a goal that we can achieve, "says Sebastian Corbisiero, who is responsible for leading the project.

NASA used the moon as a stage for a manned journey to the Mars believes that a nuclear power plant that is independent of sunlight will provide sufficient energy regardless of the environmental conditions on the moon or Mars. The US Department of Energy and NASA have been talking about the concept of "fission surface powerr "by fission. This is a nuclear reactor with an output calculated in kilowatts. By fissioning uranium nuclei, it would produce an output of at least 10 kilowatts.

Collisions of neutron stars enrich the universe more than the merging of black holes with stars

Scientist of the MIT from LIGO and the University of New Hampshire calculated the amount of heavy elements produced when black holes merge with neutron stars and compared their data with the amount of heavy elements produced when neutron stars merge. Hsin-Yu Chen, Salvatore Vitale and Francois Foucart used advanced simulation systems and data from the Gravitational wave observatories LIGO-Virgo.

Currently, astrophysicists do not fully understand how elements heavier than iron form in the universe. They are believed to arise in two ways. About half of these elements are formed during the process s in stars of low mass (0,5-10 solar masses) in the final stages of their life. They are then red giants. There takes place Nucleosynthesis instead of when fast Neutrons be captured by nuclides with low neutron density and medium temperatures.
