The world of physics in 2024 through the eyes of ChatGPT
In 2024, something extraordinary has been discovered in physics. These include nuclear and medical physics, quantum computing, lasers, antimatter and many more. The world famous science portal has listed the top 10 from Physics World. I can also look at those physics lists at a glance.
Ways to make mouse skin transparent
Researchers at Stanford University in the US used a food grade yellow dye to make the skin of living mice transparent. This makes it easier to see the liver, intestines or blood flow under the skin. Scientists hope to use this method in human treatment in the future.
Cooling positronium with a laser
Researchers at the European Center for Nuclear Research CERN and the University of Tokyo have cooled an antimatter particle called positronium using lasers.
Scientists are considering this as a milestone in validating various theories of the Standard Model of antimatter and particles.
Simulation techniques in lung cancer
Researchers in the UK, Germany and the US have developed a computer model. This will help to apply radiotherapy more precisely to cancer patients. Researchers hope it will be effective in reducing damage to healthy cells.
Graphene is a new semiconductor
A group of scientists have developed a new type of semiconductor and logic switch using graphene. It can perform memory and logic functions simultaneously. It will help speed up data processing and reduce power consumption.
Direct observation of nuclear decay
A group of researchers from Yale University in the United States placed lead-212 nuclei in silica balls and observed the nuclear radiation decay process. The researchers believe that this method can be used for neutrino detection in the future.
A new model of the nucleus
Andrew Denniston of MIT in the United States and Thomas Jejo, a researcher at the University of Münster in Germany, combined two different theories of the nucleus for the first time. They unified both the quark-gluon model of the nucleus and the conventional proton-neutron model of nuclear physics. This will give a more detailed understanding of the structure of the nucleus and the strong nuclear force.
Low-cost titanium-sapphire lasers
Scientists at Stanford University in the US have developed a small and cost-effective titanium-sapphire laser. Researchers believe it will revolutionize the use of lasers in research and industry.
Error correction in quantum computing
Researchers at Google and Harvard University have developed advanced technology for error correction in quantum computers. They demonstrated quantum error correction using 48 logical qubits in an atomic processor. They also implemented quantum error correction below the 'surface code threshold' in a superconducting chip.
Noise produced by interactions with the environment is a major weakness of quantum computers. Solving this problem is considered a key challenge for quantum technology.
The research team, by working with a completely different quantum system, has taken important steps to overcome this challenge. Their success greatly increases the possibility that in the future quantum computers will become not just a research tool, but an effective tool for solving real-world problems. As a result, this research will make quantum computers more efficient and practical.
Enhanced imaging via entangled photons
Researchers in France and the UK have captured high-quality images using quantum photons. Using entangled photons has opened up new possibilities in imaging. Chloe Vernier and Hugo Defien of Sorbonne University in France made this team. Together they were able to encode an optical image using quantum entanglement.
The peculiarity of this method is that the image can only be seen when an observer uses a single-photon sensitive camera. Otherwise it remains invisible. This technique can be used to develop advanced imaging systems in biological tissue and long-distance optical communication.
At the same time, Vernier and Defien, along with Patrick Cameron of the University of Glasgow in the UK and others, developed adaptive optical imaging using entangled photons. Their research shows that this method can produce higher-resolution images than conventional bright-field microscopy. This adaptive optics approach could play an important role in the development of quantum microscopes.
Collecting samples from the dark side of the Moon
China's National Space Administration collected samples from the far side of the moon for the first time. Landing on this part of the moon is extremely difficult because it is on the opposite side of the Earth and has huge craters and uneven terrain.
Scientists are particularly interested in this part of the moon, because it is very different from the near side of the moon. Research on this part of the Moon is important to understand the reasons for this difference.
