Study shows Black households pay higher heating costs, seek cold-related medical care more often
Ticking up the thermostat a degree or two is going to cost anyone more money, but a new study from UConn researchers suggests Black households pay more to keep their homes comfortable, in part due to increased cold sensitivity......»»
A close look at changes to the skin biome after ear piercing
A team of microbiologists at McGill University's Redpath Museum, working with a colleague at Tattoo Lounge MTL, has investigated changes to the skin microbiome when a person has an ear pierced and a metal object inserted into the puncture. In their s.....»»
Nanodiamonds can block tumor metastasis in mice, study shows
Nanodiamonds are 2–8 nm carbon nanoparticles, which can be easily functionalized with various chemical groups like carboxylic groups or drugs. Previous research has shown that actively dividing cells are more likely to absorb nanodiamonds and that.....»»
