The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fiberglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study conducted on glass nanofibers. The pathogenic potential of inhaling the inert fibrous nanomaterials used in …

Phosphorus is essential for undisturbed plant growth and development. However, in many soils, phosphorus is only poorly available. One mechanism used by plants to increase phosphorus availability is the release of malate, an organic acid, which can form complexes with iron or aluminium in the soil, thereby liberating sorbed phosphate. However, this response can also …

Rapid-acting antidepressants, including ketamine, scopolamine and psilocybin, have been found to have immediate and lasting positive effects on mood in patients with major depressive disorder but how these effects arise is unknown. New research has explored their neuropsychological effects and found that all three of these drugs can modulate affective biases associated with learning and …
Scientists have produced an organoid model of the human conjunctiva. These organoids mimic the function of the actual human conjunctiva, a tissue involved in tear production. Using their new model, the researchers discovered a new cell type in this tissue: tuft cells. The tuft cells become more abundant under allergy-like conditions and are therefore likely …

Increases in symptoms of depression are associated with a subsequent increase in bodyweight when measured one month later, new research has found. The study found that the increase was greatest among people with overweight or obesity, but found no link between generally having greater symptoms of depression and higher bodyweight. Increases in symptoms of depression …
