How macrophages regulate regenerative healing in spiny mice      (via sciencedaily.com)     Original source 

A team of researchers is delving deeper into the science behind how spiny mice can regenerate lost tissue and using what they learn to trigger regeneration in other types of mice -- advances which one day may be translated into humans. Whereas adult laboratory mice heal injuries with scar tissue, spiny mice have the unique ability to regrow lost skin and regenerate musculoskeletal tissues in their body.

Researchers pinpoint most likely source of HIV rebound infection      (via sciencedaily.com)     Original source 

Antiretroviral therapy (ART) does an excellent job at suppressing HIV to undetectable levels in the blood. However, small amounts of latent virus hide throughout the body, and when treatment is stopped, it opens the door for the virus to rebound. Researchers identified which tissues SIV, the nonhuman primate version of HIV, reemerges from first, just seven days after ART is stopped.

World's first successful embryo transfer in rhinos paves the way for saving the northern white rhinos from extinction      (via sciencedaily.com)     Original source 

Scientists have succeeded in achieving the world's first pregnancy of a rhinoceros after an embryo transfer. The southern white rhino embryo was produced in vitro from collected egg cells and sperm and transferred into a southern white rhino surrogate mother at the Ol Pejeta Conservancy in Kenya on September 24, 2023. The BioRescue team confirmed a pregnancy of 70 days with a well-developed 6.4 cm long male embryo. The successful embryo transfer and pregnancy are a proof of concept and allow to now safely move to the transfer of northern white rhino embryos -- a cornerstone in the mission to save the northern white rhino from extinction.

Towards the quantum of sound      (via sciencedaily.com)     Original source 

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in wave-guides. Unwanted noise generated by the acoustic waves at room temperature can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of sound and is relevant to quantum communication systems and future quantum technologies.

Higher measurement accuracy opens new window to the quantum world      (via sciencedaily.com)     Original source 

A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).
