Solving a natural riddle of water filtration

For many engineers and scientists, nature is the world s greatest muse. They seek to better understand natural processes that have evolved over millions of years, mimic them in ways that can benefit society and sometimes even improve on them.
An international, interdisciplinary team of researchers that includes engineers from The University of Austin has found a way to replicate a natural process that moves water between cells, with a goal of improving how we filter out salt and other elements and molecules to create clean water while consuming less energy. ....

New method of producing drug candidates may lead to better medicines in the future


New method of producing drug candidates may lead to better medicines in the future
A lot of our medicines and other bioactive drugs are based on chemical structures called enantiomers molecules that are mirror images of each other and are non-superimposable. Notable among them are chiral N,N-acetals contained in diuretic drugs like bendroflumethiazide and thiabutazide, used to treat high blood pressure and edema.
Because an enantiomer and its mirror image version often have different biological activities, with only one of them having pharmacological utility, an enantioselective or asymmetric synthesis yielding the desired enantiomer in greater amounts is highly desirable. ....
