Summary: A new study explores how the human brain constructs emotions, regardless of sensory input.
By analyzing brain activity in individuals with and without sensory deprivations while they experienced the film 101 Dalmatians, researchers discovered that emotions are represented in the brain through an abstract coding system that transcends sensory modalities. This system involves a distributed network, including the ventromedial prefrontal cortex, which stores abstract representations of emotions.
The findings challenge traditional views on emotion and perception, suggesting that our emotional experiences are not solely dictated by our immediate sensory input but are instead constructed by the brain in a more abstract manner.
A research team has successfully synthesized a metal nanocluster and determined its crystal structure. Their study provides experimental evidence for understanding and designing nanoclusters with specific properties at the atomic level. Metal nanoclusters have wide-ranging applications in the biomedical field.
Their work is published in the journal Polyoxometalates.
Scientists have shown interest in ligand-protected atomically precise metal nanoclusters because they have definite atomic structures and exceptional physical and chemical properties. These properties include attributes such as luminescence, chirality, electrochemistry, and catalysis.
Retrotransposons can insert new genes into a “safe harbor” in the genome, complementing CRISPR gene editing.
The recent greenlighting of a CRISPR-Cas9 treatment for sickle cell disease underscores the efficacy of gene editing technologies in deactivating genes to heal inherited illnesses. However, the capability to integrate entire genes into the human genome as replacements for faulty or harmful ones remains unachievable.
A new technique that employs a retrotransposon from birds to insert genes into the genome holds more promise for gene therapy, since it inserts genes into a “safe harbor” in the human genome where the insertion won’t disrupt essential genes or lead to cancer.

As a developmental neurobiologist at Harvard University, Paola Arlotta spends most of her time thinking about how the brain develops, how it functions, and what goes wrong in the context of neurological disease. Using human brain organoids as a model for brain development and disease research has been a game changer, providing Arlotta a novel view into brain pathologies that form in utero.
Symmetries aren’t just about folding or rotating a piece of paper, but have a profound array of applications when it comes to physics.
“That let us faithfully model peripheral vision the same way it is being done in human vision research,” says Harrington.
The researchers used this modified technique to generate a huge dataset of transformed images that appear more textural in certain areas, to represent the loss of detail that occurs when a human looks further into the periphery.
Paraconsistent logic is a method of reasoning about inconsistencies without falling into absurdity.
