Credit: POSTECH Newly developed photoacoustic microscopy uses vibrations generated when light is absorbed and captures images of cells or blood vessels. This development has increased the possibility of peering inside the body without contrast agents. However, obtaining...
by Leslie Tate, Tulane University Host nutrient metabolism is altered in response to viruses. a, Viruses such as HCV and SARS-CoV-2 interact with entry/metabolic factors to increase fatty acid synthesis, triglycerides and lipid droplets essential for replication and trafficking of viruses to the cell membrane. b, Interactions between HIV and its entry/metabolic factors trigger PI3K–mTOR–HIF-1α...
CHINESE ACADEMY OF SCIENCES HEADQUARTERS The hypothalamus, one of the most complex brain regions in the mammalian nervous system, contains an astonishing heterogeneity of neurons that regulate endocrine, autonomic and behavioral functions. It not only regulates food consumption, water intake, body temperature, circadian rhythm and sleep to maintain the survival of individual organisms, but also...
