Using a trapped-ion quantum computer, the research team witnessed the interference pattern of a single atom caused by a 'conical intersection'. Conical intersections are known throughout chemistry and are vital to rapid photo-chemical processes such as light harvesting in human vision or photosynthesis.

Researchers have developed and demonstrated a new method for high-throughput single-cell sorting that uses stimulated Raman spectroscopy rather than the traditional approach of fluorescence-activated cell sorting. The new approach could offer a label-free, nondestructive way to sort cells for a variety of applications, including microbiology, cancer detection and cell therapy.

The NSL (non-specific lethal) complex regulates thousands of genes in fruit flies and mammals. Silencing the NSL genes leads to the death of the organism, which gave the complex its curious name. Researchers have now discovered that the genes regulated by the NSL complex also include genes of the intraciliary transport system. This enables different cell types to form cilia on their surface, which are important for cell communication. The study shows that these genes are 'switched on' by the NSL complex, regardless of whether a particular cell has cilia or not. The researchers found that this class of cilia-associated genes is crucial for the function of podocytes. This is a highly specialized cell type of the kidney that, paradoxically, does not have cilia. These findings have important implications for ciliopathies and kidney disease.

A bitter taste in the mouth is often a symptom or side effect of illness, which may be the result of how the body reacts to pathogens. A new study sheds light on the mechanisms involved in the complex interplay between taste perception and immune function. Their work also highlights the potential of a sequencing tool for investigating epigenetic mechanisms that affect taste-cell gene expression.

Researchers have discovered a novel approach for engrafting engineered cells into injured lung tissue. These findings may lead to new ways for treating lung diseases, such as emphysema, pulmonary fibrosis and COVID-19. The two studies describe the methodologies for engineering lung stem cells and transplanting them into injured experimental lungs without immunosuppression.

The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.

A researcher made a discovery that could change our understanding of the universe. He reveals that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it.

Regulatory genes -- genes that control how other genes are used -- are responsible for 69% of the heritability of dairy cattle traits such as milk production and fertility, according to a new study. This contribution is 44% more than expected and much higher than previous studies of regulatory genes in humans. The findings, reported by a team of animal and human geneticists, could improve the efficiency of agricultural breeding programs. The study also helps solve the longstanding mystery of why mammalian genomes contain so much noncoding DNA.
