Epigenetic changes play important roles in cancer, metabolic and aging-related diseases, but also during loss of resilience as they cause the genetic material to be incorrectly interpreted in affected cells. A major study now provides important new insights into how complex epigenetic modification signatures regulate the genome. This study will pave the way for new treatments of diseases caused by faulty epigenetic machineries.

Researchers developed protocols for growing organoids that mimic a turtle liver, the first organoids developed for a turtle and only the second for any reptile. The discovery will aid deeper study of turtle genetics, including the cause of traits with potential medical applications for humans such as the ability to survive weeks without oxygen.

Researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity can be as high as 97.5% in GaAs quantum dots. This work may be useful to achieve fast and high-fidelity quantum computing.

A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.

Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.

Scientists have pioneered a new methodology of fabricating carbon-based quantum materials at the atomic scale by integrating scanning probe microscopy techniques and deep neural networks. This breakthrough highlights the potential of implementing artificial intelligence at the sub-angstrom scale for enhanced control over atomic manufacturing, benefiting both fundamental research and future applications.

As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.
