"Hairy" cellulose could reduce side effects of chemotherapy

A new Nanomaterial can "stray" chemotherapeutic molecules intercept before they can damage healthy tissue. Therefore, there is hope that the side effects of chemotherapy both during and after treatment. The main component of the nanomaterial are "hairy" nanocrystals made of cellulose. The developers claim that 1 gram of such crystals is more than 6 grams of commonly used chemotherapy drug doxorubicin (DOX) can capture. This makes it 320 times more potent than previous DNA-based alternatives.

The taking of cancermedication brings with it a whole range of side effects, such as B. hair loss, the development of anemia and jaundice. Scientists are trying to minimize these effects by looking for ways to increase the concentration of the Blut circulating chemotherapy drugs. Among the proposed solutions are the use of catheters with special resins or the introduction of with DNA coated magnetic nanoparticles into the body.

Artificial intelligence will examine the eyes and calculate the risk of a heart attack

At the University of Leeds a system with artificial intelligence (AI) that analyzes eye scans taken during routine visits to the optometrist or optometrist and identifies those who are at high risk of heart attack. The system analyzes changes in the miniature blood vessels of the retina, which we know to be on a broader cardiovascular problem . indicate

The Leeds specialists used deep learning techniques to train the AI ​​to automatically read the scans and identify the people most likely to have a heart attack within the next year.

The system that Nature Machine Intelligence is characterized by an accuracy of 70-80 percent and, according to the developers, could be used to diagnose Cardiovascular diseases be used.

Webb has reached its destination and entered its intended orbit

After a month's journey, this is it James Webb Space Telescope (JWST) straight into orbit around the Lagrange point L2 occurred. Over the next five months, Webb will be prepared for operations, with scientific research due to begin in June

The mirrors and scientific instruments of Webb have not yet reached the required stable operating temperature. You still need to cool down a bit. And they started to cool down, and very quickly, as soon as the telescope saw the heat shield unrolled. However, this process is not left to nature alone. It is tightly controlled by placing electrically heated strips at strategic points on the telescope. Thanks to this it was possible both the uniform shrinkage throughout telescopic structure both to control and to ensure that the moisture absorbed by the earth evaporates and does not freeze to the optics or sensors, which could hamper scientific research.

Killing bacteria with lasers. Light copes with antibiotic-resistant pathogens

The world is facing a growing crisis Antibiotic resistance faced. The excessive use of Antibiotics in medicine, the food industry and in cosmetics leads to the occurrence of antibiotic-resistant bacteria. The penetration of antibiotics into the environment, with concentrations in some rivers exceeding safe levels by 300 times, forces the pathogens to continuously develop antibiotic resistance. Hundreds of bacterial antibiotic resistance genes have even been discovered in the intestines of children. Without new antibiotics or other solutions, the scenario of people dying again from common infections or currently harmless diseases becomes real.

A strategy outside of the chemical repertoire is use physical methods such as ultraviolet light, gamma radiation, or heat. While these methods are effective in inactivating pathogens, they cause severe tissue damage and therefore cannot be used in clinical practice.

It is for this reason that some scientists are interested in this visible light. At low intensity it is gentle on the tissue and at the same time has the ability to inactivate bacteria, viruses and other pathogens. Specialists studying this problem are especially interested in Femtosecond laserthat emit ultrashort light pulses, the duration of which is specified in femtoseconds (1 femtosecond is 1/1 000 000 000 000 000 second).

Bizarre and mysterious patents owned by the US military. Mad, genius or patent troll

The US Navy has a technology to "improve the structure of reality", a compact fusion reactor, an engine that works on the principle of "Inertia mass reduction" works, and many other strange sounding things are patented. The US patent law in the USA allows the application of these so-called "UFO Patents". However, it is claimed that there must have been some prototypes.

At least that is what the website "The War Zone" claims, which is a journalistic investigation of this enigmatic Patent has performed. It has been proven that Dr. Salvatore Cezar Pais is behind it. Although his picture is known, journalists write that it is uncertain whether this person really exists. According to Pais, he worked for many different departments in the Navy, including the Naval Warfare Center Aviation Division (NAVAIR / NAWCAD) and the Strategic Systems Programs (SSP). SSP's mission is to provide reliable and affordable strategic solutions for the military. ”Among other things, she is responsible for developing the technology for nuclear submarine missiles of the Trident class.

Convolution theory or knot theory in math is not an easy problem? DeepMind does its job quite well

DeepMind based on artificial intelligence and has already helped solve even the most difficult puzzles several times. This time it was about knots mathematicians have been grappling with for many years

The subject of the research was something called a guess, which is an unconfirmed sentence that appears to be correct. Algorithms of the machine learning  have been used before in mathematics to develop such theoretical ideas, but they were not as complex as in this case. The authors of this breakthrough have their success in Nature described.

The biggest launch in history and the most important in 30 years, the James Webb Space Telescope launches today

An Ariane 5 rocket is due to launch between 13.20:13.52 and XNUMX:XNUMX p.m. German time today James Webb Space Telescope (JWST) take off. This will be the largest scientific instrument ever put into space by humans and the most important in the 31 years since the Hubble telescope was launched. Contrary to popular belief, the Webb telescope is not intended to be a replacement for Hubble, but rather a supplement. Scientists from all over the world have great expectations of the observatory, its structure and the NASA the European Space Agency and the Canadian Space Agency are also involved.

The launch of the extraordinary telescope can be seen live on the YouTube channel of NASA be followed.

Star Trek Today: Alcubierre Warp Metric: Scientists succeed in creating a "warp bubble"

A team of scientists doing research for DARPA accidentally got one "Warp" effect creates a very small object with properties similar to those of the Mexican scientist Miguel Alcubierre in his theoretical work from the 1990s. The "thing" is the result of an experiment with a different purpose carried out by scientists at the Limitless Space Institute.

"When performing analyzes as part of a DARPA-funded project to evaluate the possible structure of energy density in empty Casimir space as predicted by the dynamic model of vacuum," says an im European Physical Journal published article, "a structure was discovered on the micro / nano scale that is negative Energy density distribution signals that comes very close to the requirements of the Alcubierre metric ".

Spread of brain tumors explained using principles of fluid physics

Josef Käs from the University of Leipzig and Ingolf Sack from the Charité-Universitätsmedizin Berlin have shown that the spread of Brain tumor cells depends on both their physical and biomechanical properties. According to the researchers, a small change in the elasticity of glioma cells - the most dangerous brain tumor - significantly changes its ability to metastasize.

Sack is a chemist and Käs is a physicist. Both specialize in cancer research, but from different perspectives. Sack studies the mechanical properties of fabrics and has the technology of Magnetic resonance elastography developed a combination of low frequency vibrations and Magnetic resonance. It is used to track the progress of diseases. Käs, on the other hand, works with one optical trap, in which soft miniature objects such as cells can be deformed with the help of lasers to create their elasticity and to investigate deformability.

An optical oscilloscope was developed. Will it make the internet 10 times faster?

At the University of Central Florida became the first optical oscilloscope the world developed. The device could do the Communication technologies revolutionize, from smartphones to the internet. The device developed at UCF measures the electric field of light by converting light oscillations into an electrical signal.

So far, the measurement of the electric field of light due to its enormous Vibration speed a big problem. The most advanced measurement techniques used in electronic and telecommunications equipment allow the measurement of frequencies on the order of gigahertz. This includes the radio and microwave spectrum of the electromagnetic radiation. However, light vibrates at a much higher frequency. So it is possible to put in a lot more information than we do today. However, we do not have the appropriate tools. Current oscilloscopes perform averaged measurements within a light pulse. You cannot distinguish between individual valleys and wave crests. If we could measure individual valleys and mountains, we could encode information into them.
