In a new Nature Physics study, researchers have provided evidence of universal conformal invariance in living biological cells. They show that a universal feature in the collective behavior emerges in groups of living cells.
The researchers studied four cellular systems to find evidence of universal conformal invariance. Despite being separated by billions of years of evolution, the researchers found that all four systems generated vortex-like flow patterns with identical statistical properties.
Phys.org spoke to one of the study’s co-authors, Dr. Amin Doostmohammadi, an Associate Professor at the University of Copenhagen.
During the past two decades, gut microbiome studies have established the significant impact of the gut microbiota and its metabolites on host health. However, the molecular mechanisms governing the production of microbial metabolites in the gut environment remain insufficiently investigated and thus are poorly understood. Here, we propose that an enhanced understanding of gut microbial gene regulation, which is responsive to dietary components and gut environmental conditions, is needed in the research field and essential for our ability to effectively promote host health and prevent diseases through interventions targeting the gut microbiome.
Neurobehavioural disturbances such as loss of motivation have profound effects on the lives of many people living with Parkinson’s disease (PD), as well as other brain disorders. The field of decision-making neuroscience, underpinned by a plethora of work across species, provides an important framework within which to investigate apathy in clinical populations. Here we review how changes in a number of different processes underlying value-based decision making may lead to the common phenotype of apathy in PD. The application of computational models to probe both behaviour and neurophysiology show promise in elucidating these cognitive processes crucial for motivated behaviour. However, observations from the clinical management of PD demand an expanded view of this relationship, which we aim to delineate. Ultimately, effective treatment of apathy may depend on identifying the pattern in which decision making and related mechanisms have been disrupted in individuals living with PD.
Even by the standards of today’s AI market, $2 billion of funding for a startup less than a year old with no product is a gargantuan sum and would rank as one of the largest seed rounds in history.
Physicists have replicated the famous Schrödinger’s cat experiment at hotter temperatures than ever before. The breakthrough is a small but significant step toward quantum computers that can work at normal temperatures.
This study identifies MYO1F as a pivotal regulator of the immunosuppressive capabilities and expansion of tumor-associated neutrophils during cancer progre

Explore the world of scientific models and their effectiveness in explaining reality, from Einstein’s Theory of Relativity to Darwin’s Theory of Evolution. Discover why some argue that these models are true explanations, while others view them as superfluous to the theories of science.
Join us this episode as we explore how a cutting-edge, high-throughput screening platform can identify lifespan-extending compounds in diverse model organisms, with Dr Kevin Perez, co-founder of Epiterna and Junior Group Leader at Charité Universitätsmedizin Berlin, and host Prof Brian Kennedy, Director of the Centre for Healthy Longevity at #NUSMedicine.
