New work achieves a pure quantum state without the need for cooling

Three nano-glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one another—only much smaller. The diameter of the nano cluster is ten times smaller than that of a human hair.

With the help of an optical device and , researchers at ETH Zurich have succeeded in keeping such objects almost completely motionless in levitation. This is significant when it comes to the future development of quantum sensors, which, together with quantum computers, constitute the most promising applications of quantum research.

The team’s work appears in Nature Physics.

Researchers discover universal rules of quantum entanglement across all dimensions

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online in Physical Review Letters.

“This study is the first example of applying thermal effective theory to quantum information. The results of this study demonstrate the usefulness of this approach, and we hope to further develop this approach to gain a deeper understanding of quantum structures,” said lead author and Kyushu University Institute for Advanced Study Associate Professor Yuya Kusuki.

In , two particles that are far apart behave independently. However, in , two particles can exhibit strong correlations regardless of the distance between them. This quantum correlation is known as quantum entanglement.

Scientists develop method to optimize delivery of mRNA to cells

Researchers have developed a simple yet highly effective method for delivering mRNA to target cells, opening up new possibilities for future non-vaccine mRNA medicines for a broad range of diseases.

The Monash University study, published in Nature Nanotechnology, is a significant development in how mRNA is precisely delivered to cells to maximize efficacy and minimize off-target effects—vital components for future mRNA medicines as they continue to evolve.

Led by the Monash Institute of Pharmaceutical Scientists (MIPS), the interdisciplinary team of researchers used advanced technologies coupled with preclinical studies to produce a highly versatile method that captures and attaches antibodies to the surface of mRNA-loaded while the antibodies are in their optimal orientation, thus enhancing the mRNA’s effectiveness and reducing side effects by making sure it only reaches its target destination.

Lysosomal membrane homeostasis and its importance in physiology and disease

Lysosomes degrade cellular components, and their membrane is an important signalling hub. Recent insights into the mechanisms that maintain lysosomal membrane homeostasis — including the interplay between membrane damage, repair, lysophagy and lysosome biogenesis — highlight their importance in physiology, in disease and during ageing.

NIA, NINDS: UNTANGLING THE VIRAL LINK TO NEURODEGENERATION

Scientists have long sought to understand the connection between viral infections and brain health. Can common viruses, which can reside unnoticed within our bodies, contribute to the development of neurodegenerative diseases such as Alzheimer’s and other forms of dementia? A study published in Science Advances led by researchers at the NIA tapped into data from thousands of human subjects offers compelling new insights into this enigmatic area of research.

The investigation examined the neurocognitive and plasma proteomic profiles of older adults in a community-based cohort from the Baltimore Longitudinal Study of Aging. Researchers focused on their antibody responses to four common coronaviruses and six herpesviruses with hopes of uncovering the molecular pathways linking the immune response to these viruses with brain aging and dementia risk.
