Chirality in real time

Distinguishing between left-handed and right-handed (chiral) molecules is crucial in chemistry and the life sciences, and is commonly achieved using a method called circular dichroism. However, during biochemical reactions, ...

Progress in super-resolution microscopy

Going deeper and deeper into cells with the microscope; imaging the nucleus and other structures more and more accurately; getting the most detailed views of cellular multi-protein complexes: All of these are goals pursued ...

Researchers find some cider makers add unneeded sugar

It's the holiday season and the time of year when there are plenty of libations at nearly every event and or celebration. However, you may not be aware of all the ingredients in your favorite libation, especially if that ...

Seeing small-molecule interactions inside cells

Like people in a large company, proteins in cells constantly interact with each other to perform various jobs. To develop new disease therapies, researchers are trying to control these interactions with small-molecule drugs ...

Researchers develop smartphone-based ovulation test

Investigators from Brigham and Women's Hospital are developing an automated, low-cost tool to predict a woman's ovulation and aid in family planning. Capitalizing on advancements in several areas, including microfluidics, ...

Capturing the surprising flexibility of crystal surfaces

Images taken using an atomic force microscope have allowed researchers to observe, for the first time, the flexible and dynamic changes that occur on the surfaces of 'porous coordination polymer' crystals when guest molecules ...

Physicists shed X-ray light on melting polymers

Physicists from the Moscow Institute of Physics and Technology (MIPT) and Lomonosov Moscow State University have combined thermal analysis and X-ray scattering—two techniques for studying crystal structure—in one experimental ...

Authenticating the geographic origin of hazelnuts

Hazelnuts, like olive oil, cheese and other agricultural products, differ in flavor depending on their geographic origin. Because consumers and processors are willing to pay more for better nuts—especially in fine chocolates ...

How a crystal is solvated in water

Researchers at Ruhr-Universität Bochum have observed how a molecule from a solid crystal structure is solvated in a liquid solvent at a molecular level for the first time. The process is too fast to decipher at room temperature. ...
