Eating Ourselves into Shorter, Less Healthy Lives

We humans have not evolved for optimal function given a continually high calorie intake. We, and all other species, evolved in an environment characterized by periods of feast and famine: we desire food constantly,...

Neuronal cultures advance ‘brain-on-a-chip’ technology

Lawrence Livermore National Laboratory (LLNL) researchers have increased the complexity of neuronal cultures grown on microelectrode arrays, a key step toward more accurately reproducing the cellular composition of the human brain outside the body. As described...

High concentrations of toxic pollutants were detected in stranded whales, dolphins

A study led by researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales along the southeastern coast of the United...

Researchers investigate the survivability of E. coli bacteria based on fast or slow growth

Bacteria are survival artists: When they get nutrition, they multiply rapidly, albeit they can also survive periods of hunger. But, when they grow too quickly, their ability to survive is hampered, as studies by...

Single-cell analysis uncovers fibroblast heterogeneity and criteria for fibroblast and mural cell identification and...

Gene expression demarcates fibroblasts from mural cells Cells were collected from adult mouse heart, skeletal muscle, colon, and urinary bladder based on their expression of reporters and/or antibody-recognized epitopes for platelet-derived growth factor receptor-α (Pdgfra)...

An Age-Related Increase in CD47 Expression Impairs Vascular Function

Researchers here provide evidence to indicate that increased expression of CD47 in aged blood vessels impairs a range of functions, from maintenance of these tissues to the generation of new blood vessels. The latter...
