(PhysOrg.com) -- To study the behavior of large protein complexes and long DNA chains in solution, researchers use so-called molecular traps. However, earlier traps have proven ineffective when working with small molecules ...
Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. ...

(Phys.org)—Biopharmaceutical macromolecules are often functionalized with polyethylene glycol (PEG), an inert chain of -(CH2CH2O)- repeating units. PEG can help make a biomolecule more soluble in water, or increase its ...
(Phys.org)—Diseases like mad cow disease or Alzheimer's are a result of protein mis-folding. Proteins are comprised of an amino acid chain that folds into a three-dimensional structure. According to the Anfinsen Principle, ...
(Phys.org) —New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources ...
