| Researchers identify key regulator of blood stem cell development Posted: 28 Jan 2022 12:35 PM PST A protein that masterminds the way DNA is wrapped within chromosomes has a major role in the healthy functioning of blood stem cells, which produce all blood cells in the body, according to a new study. |
| Leafy greens first dished up 3,500 years ago Posted: 28 Jan 2022 11:13 AM PST Leafy vegetables accompany many West African dishes, such as pounded yam in the south of the region. Researchers have now successfully shown that the origins of such dishes date back 3,500 years. |
| Human disturbance is the most crucial factor for lynx in habitat selection Posted: 28 Jan 2022 11:13 AM PST Habitat selection in wildlife is a process that occurs at different scales: Balancing advantages, such as high abundance of food, with disadvantages, such as human disturbance. Large predators, with their large spatial requirements, are particularly sensitive to these disturbances. |
| Blocking sphingolipids counteracts muscular dystrophy Posted: 28 Jan 2022 11:12 AM PST Scientists have made a link between muscular dystrophy and a group of bioactive fats, the sphingolipids, which are involved in numerous cell functions and other diseases. |
| Artificial muscles made of proteins Posted: 28 Jan 2022 11:12 AM PST A research team has developed a material made of natural proteins that contracts autonomously. |
| Posted: 28 Jan 2022 07:07 AM PST A new study has determined the post-mortem interval of human skeletal remains using real samples, which has been made possible by the combination of two non-destructive analytical tools: Raman spectroscopy and chemometrics. This opens up new avenues for dating in the field of forensic medicine and anthropology. |
| Txikispora philomaios, a parasite that will help to explain the origin of animal multicellularity Posted: 28 Jan 2022 07:07 AM PST Researchers have discovered a parasite present in seawater and which belongs to a primitive lineage; they have named it Txikispora philomaios. This organism will help to explain how multicellularity developed in animals. |
| Crowding, climate change, and the case for distancing among trees Posted: 27 Jan 2022 02:26 PM PST In the age of large-scale fires, forest-wide beetle invasions, and frequent drought, maintaining 'ideal' historical conditions is becoming increasingly unrealistic. Novel conditions require different strategies; lower crowding for trees can increase chances of survival after fire. Results from two long-term studies show that chances for long-term tree survival increased when trees had more space, by reducing competition and helping trees recover from fire more quickly. |
| Gene regulation: How long do proteins bind? Posted: 27 Jan 2022 11:15 AM PST Researchers show how a DNA-binding protein can search the entire genome for its target sequence without getting held up on the way. The result contradicts our current understanding of gene regulation - the genetic code affects how often the proteins bind, but not for how long. |
