Chaperones are molecular machines that help proteins in the cell fold into their proper shape. Among them, UNC45 plays a critical role in muscle health by ensuring the proper function of myosin, a key protein essential for muscle movement. UNC45 manages this by directing damaged myosin to degradation pathways while guiding correctly folded myosin toward assembly. Researchers from Tim Clausen’s lab at the IMP have uncovered the mechanisms behind this process, providing new insights into how disruptions in myosin quality control can lead to serious muscle disorders. Their findings have been published in Nature Communications.

Muscle movement relies on the interaction between two key proteins: actin and myosin. These proteins slide past each other to generate the force needed for movement. For this process to work efficiently, actin and myosin must be precisely organized within the sarcomere, the basic structural and functional unit of muscle cells. This arrangement is crucial for maintaining muscle health, particularly during exercise, periods of stress, and as the body ages.

To ensure proteins achieve their correct shape, cells use specialized molecular assistants called chaperones. These chaperones act as caretakers, helping proteins fold and assemble correctly. For myosin, which makes up about 16% of the total protein in muscle cells, proper structure is especially important. One critical chaperone for this task is UNC45, found in all eukaryotic organisms. Identified through genetic studies, UNC45 plays a vital role in shaping myosin and preserving the integrity of the sarcomere. The importance of UNC45 is evident in severe muscle disorders, known as myopathies, which can result from mutations in the UNC45 gene.

The ICI Meeting 2024 is an acclaimed forum which aims to explore fuel, spark and be involved in the innovations that will shape the future of our cardiovascular systems.

As we explore space outside our solar system, genetic engineering offers hope for overcoming challenges like radiation exposure and the effects of microgravity. By understanding and modifying our genes, we could make astronauts more resilient and improve their health in space. However, these advancements raise important ethical questions about safety, fairness, and long-term impacts, which must be carefully considered as we develop new space travel technologies.

We are on the edge of exploring space outside our solar system. This is not just a major advancement in technology, but a transformation for all of mankind. As we aim for the stars, we also try to understand more about ourselves. Our exploration into space will determine the future of our history. However, this thrilling adventure comes with many challenges. We need to build faster spacecraft, develop ways to live sustainably in space and deal with the physical and mental difficulties of long space missions. Genetics may help us solve some of these problems. As we travel further into space, it will be important to understand how genetics affects our ability to adapt to the space environment. This knowledge will be crucial for the success of space missions and the well-being of astronauts.

Genetics offers a hopeful path to overcoming many challenges in space exploration. As we venture further into space, it becomes essential to understand how our genes affect the way we adapt to the space environment. Genetics affects many aspects of an astronaut’s ability to survive and do well in space. It influences how the body handles exposure to radiation, deals with microgravity, and copes with isolation. Some genetic differences, like changes in the Methylene-TetraHydrofolate-Reductase (MTHR) gene, can make certain people more vulnerable to the harmful effects of radiation in space. With tools like genetic testing and personalized medicine, space agencies can now choose the best-suited astronauts and develop health strategies to improve their safety and performance in harsh space conditions.

A team of engineers and environmental scientists from Mälardalen University, in Sweden, Southwest Jiaotong University, in China and Guizhou University, also in China, has developed a balloon system for producing and delivering electricity to the ground below. Their work is published in the journal Energy.

Researchers at FutureNeuro, the SFI Research Centre for Translational Brain Science, and RCSI University of Medicine and Health Sciences, in collaboration with international partners, have developed a revolutionary technique to profile gene activity in the living human brain.

This innovative approach, published in JCI Insight, opens new avenues for understanding and treating neurological conditions like epilepsy.

Studying gene activity in the brain without requiring invasive tissue samples from surgery or post-mortem donation has been a long-standing challenge in neuroscience. By analyzing molecular traces – specifically RNA and DNA – collected from electrodes implanted in the brains of patients with epilepsy and linking these with electrical recordings from the brain, the researchers were able to take a ‘snapshot’ of gene activity in the living brain.

The Space Coast set a new launch record in 2023 with 72 orbital missions from either Kennedy Space Center and Cape Canaveral Space Force Station. The pace of launches could ramp up by the end of 2024 to a near twice-weekly rate with as many as 111 missions possible.
