| Monitoring the 'journey' of microplastics through the intestine of a living organism Posted: 23 May 2022 07:22 AM PDT A UAB research team has managed to track the behaviour of microplastics during their 'journey' through the intestinal tract of a living organism and illustrate what happens along the way. The study, carried out on Drosophila melanogaster using electron microscopy equipment developed by the researchers themselves, represents a significant step towards a more precise analysis of the health risks of being exposed to these pollutants. |
| New measurements from Northern Sweden show less methane emissions than feared Posted: 23 May 2022 07:22 AM PDT It is widely understood that thawing permafrost can lead to significant amounts of methane being released. However, new research shows that in some areas, this release of methane could be a tenth of the amount predicted from a thaw. A crucial, yet an open question is how much precipitation the future will bring. |
| Men with obesity can double their sperm count Posted: 23 May 2022 07:22 AM PDT Men with obesity can double their sperm count if they lose weight and maintain the weight loss. |
| Neurons: How RNA granules grow and shrink Posted: 23 May 2022 07:22 AM PDT Scientists have shown that small aggregates function as temporary RNA repositories, which are regulated by neural activity. |
| What happens when plants have stress reactions to touch Posted: 23 May 2022 07:22 AM PDT A 30-year-old genetic mystery has been solved. It has previously been established that touch can trigger stress reactions in plants. However, the molecular models for explaining this process have been quite spartan so far. Now researchers have found genetic keys that explain how plants respond so strongly to mechanical stimuli. Cracking this code could help lead to higher yields and improved stress resistance in crops in the future. |
| A subtle genetic change gives new clues about epilepsy Posted: 23 May 2022 07:22 AM PDT Sometimes, even the alteration of a single nucleotide in a gene can cause serious disease. In a young boy with epilepsy, this kind of mutation has not just affected the functioning of the protein in question -- it could also curb the functioning of several closely related proteins. |
