The ability to uptake cellular debris and process the engulfed antigens for MHC class I presentation is mainly performed by a minority subset of dendritic cells . Immunologists identified them as “conventional-type 1 dendritic cells”, and characterized them identifying the presence of surface coexpression of CD11c, XCR1, and DNGR-1 molecules . In mice, two subsets […]
For decades, Type Ia supernovae have played a pivotal role in the discovery and study of dark energy—the mysterious force responsible for the accelerating expansion of the Universe. To do so, cosmologists compare two quantities: the redshift, i.e., the photon’s wavelength stretch caused by the geometrical expansion of the Universe ; and the Supernovae brightness […]
Cement is a fundamental material in modern construction, used in everything from buildings to bridges. One of its key components, tricalcium aluminate (C₃A), plays a crucial role in determining cement’s setting time and durability. A recent study has provided new insights into how C₃A behaves under heat, combining computer simulations with experimental data to deepen […]
A new study presents a methodology to test the assumption of cosmic homogeneity and isotropy, known as the Cosmological Principle, by leveraging weak gravitational lensing—a light distortion effect described by general relativity—in astronomical images collected by new observatories such as the Euclid Space Telescope. Finding evidence of anomalies in the Cosmological Principle could have profound […]
A new study reveals that implementing enhanced weathering (EW), the practice of adding crushed basalt to soils, with U.S. agriculture could remove between 160 and 300 million metric tons of carbon dioxide (CO2) from the atmosphere annually by 2050, rising to 250 to 490 million tons of CO2 removal by 2070. The authors demonstrate that […]
Author: Roberto Rey Agudo, Research Assistant Professor of Spanish and Portuguese, Dartmouth College The idea of a humanlike artificial intelligence assistant that you can speak with has been alive in many people’s imaginations since the release of “Her,” Spike Jonze’s 2013 film about a man who falls in love with a Siri-like AI named Samantha […]
In a recent study, a team of researchers explores the intriguing electronic behaviours that emerge when two distinct forms of carbon-based materials—nanoporous graphene (NPG) and graphene—are layered together with a twist between them. Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, renowned for its exceptional electrical conductivity, mechanical strength […]
Scientists have long puzzled over how pterosaurs became the first vertebrates to master flight. Some pterosaur species, such as the Quetzalcoatlus were the largest known animals to ever take to the skies, with wingspans of over ten meters (on par with military aircraft like the Spitfire). My team’s new study may help solve the evolutionary […]
Proteins, the pillars of cellular function, often assemble into “complexes” to fulfil their functions. A new study reveals why this assembly often begins during the very process of protein synthesis or “birth.” These early interactions involve proteins whose stability depends on their association. They can be compared to a couple in which each partner supports […]
Two-dimensional (2D) materials have become a centrepiece of modern materials science, captivating researchers with their electronic, mechanical, and optical properties. Since Geim and Novoselov discovered the exfoliation technique in 2004, thousands of 2D materials have been discovered, synthesised, or predicted. In particular, anisotropic 2D materials display direction-dependent characteristics, promising cutting-edge applications in flexible electronics and […]
