Edible Food Packaging Made From Milk Proteins
Most foods at the grocery store come wrapped in plastic packaging. Not only does this create a lot of non-recyclable, non-biodegradable waste, but thin plastic films are not great at preventing spoila...
Fentanyl’s Death Toll Is Rising
The ability of fentanyl, an opioid, to freeze chest muscles within minutes may be to blame for some overdoses, a new autopsy study shows.
Protein structure
Protein structure is the biomolecular structure of a protein molecule. Proteins are polymers – specifically polypeptides -sequences formed from various L-α-amino acids. Each unit of a protein is calle...
