Temperature responsive polymer is an interesting material that shows reversible hydration/dehydration behavior in water at 32C, termed as the lower critical solution temperature (LCST). In this video, temperature responsive block copolymers are focus....

Aquaporin channels allow water to rapidly cross cell membranes in all living organisms. AQP1 confers red cells and proximal renal tubules with high water permeability. Present in renal collecting duct, AQP2 is regulated by vasopressin, and human muta....

An interesting look at how the direction of water flow affects shell growth in barnacles.

Dr. Kroto talks about his favorite synthesis reaction in chemistry

The epidemiology of Helicobacter pylori continues to be an area of discovery and controversy in the 21st century. The transmission of this bacterium from mother to child allows Helicobacter DNA to mimic the evolution of maternal mitochondria DNA. B....

Biological research and medicine were transformed by the invention and improvement of the optical microscope. Since the early 1990s, there has been another revolution in optical imaging, and manipulation of individual biological molecules and bio-mo....

Aquaporin (AQP) water channel proteins enable high water permeability in certain biological membranes. Discovered in human red cells but expressed in multiple tissues, AQP1 has been thoroughly characterized and its atomic structure is known. Expres....

Biological membranes define and compartmentalize the cells of higher organisms. Consisting of membrane proteins and lipids, they are basically impermeable for ions and polar substances, so that electric voltages (_membrane potentialsî) and substanc....

The association of DNA with water is known since the deciphering of its double helical structure by X-Ray diffraction in 1953 (Watson, Crick, Wilkins and Franklin). However the power of DNA for organizing water seems to go far beyond the direct fill....

As scientists, our livelihoods are supported by teaching and research, but we also have the opportunity to make observations beyond our usual confines and share these with non-scientific citizens. Growing up in my native state of Minnesota, I have al....
