A new study using single-cell technology sheds light on the significance of genetic risk factors for the development of coronary artery disease, as well as the diversity of cells involved. The researchers examined human atherosclerotic lesions to map the accessibility of chromatin in over 7,000 c.....
A critical protein involved in the communication and coordination of astrocytes as they build synapses in the brain has been discovered by researchers. In the absence of this molecule, known as hepaCAM, astrocytes aren’t as sticky as they should be, preferring to stick to themselves rather .....
In a new paper published in Molecular Ecology, researchers from Flinders University investigate the relationship between the spread of Homalictus fijiensis, a common bee in Fiji’s lowlands, and land clearance, as well as the introduction of new plants and weeds into the environment. “.....
The proliferation of chromaffin cells, also known as pheochromocytes, in the rat adrenal medulla rapidly decreases after birth. In animals, these neuroendocrine cells are usually found in the medulla of the adrenal glands. These cells perform a range of activities, including stress response, moni.....
Mesolithic hunter-gatherers living in northern Siberia performed great dances during which clan members shook their clothes with cool teeth and made three-dimensional rhythmic sounds that helped the whole community enter a kind of peace. According to the author of a new study, dancers removed the.....
A catecholamine (/ˌkætəˈkoʊləmiːn/; abbreviated CA) is a naturally occurring amine that acts as a neurotransmitter and a hormone in the body. Catechol can exist as a free molecule or as a substitute for a 1,2-dihydroxybenzene group in a bigger molecule. Catecholamines have a catechol group.....
Norepinephrine (NE), also known as noradrenaline (NA) or noradrenalin, is a catecholamine hormone found in the sympathetic nervous system that acts as a neurotransmitter. It is a chemical that is released mostly from the terminals of sympathetic nerve fibers and acts to raise skeletal muscle cont.....
The gut microbiota varies greatly between individuals, but within-individual variation is relatively stable over time. A functional core microbiome supported by abundant bacterial taxa appears to be shared by all human hosts, regardless of gender, geographic location, or age. According to new res.....
DNA makes up an organism’s genome, or genetic material (bacteria, virus, potato, human). Each organism has its own DNA sequence, which is made up of bases (A, T, C, and G). You have identified an organism’s unique DNA fingerprint, or pattern, if you know the sequence of its bases. Seq.....
Bacterial cells outnumber human cells by at least a factor of ten. This community, known as the microbiome, may play a role in regulating one’s risk of obesity, asthma, and allergies. Some scientists are now wondering if the microbiome plays a role in an even more important process: mate se.....
Scientists have created polypeptide-based materials that can be used as vectors to deliver gene therapies. The platform is the first of its kind, allowing vectors to be tailored to the specific gene therapy cargo. The study, led by RCSI University of Medicine and Health Sciences researchers and f.....
Researchers have created a set of compounds that prevent the malaria parasite from bursting out of red blood cells and replicating. During their research, the scientists created a set of compounds that prevent the parasite from bursting out of red blood cells, a process critical to its replicatio.....
