Acoustic Tweezers Manipulate Protein Crystals for X-ray Crystallography

A device for precisely positioning small objects using acoustic waves has now been used to position fragile protein crystals a few micrometers or less in size in the path of a crystallography X-ray beam. This technique will make it possible to collect data on previously intractable samples and will expand the scope of what is now possible with X-ray crystallography.

New Method to Monitor Properties of Microscopic Particles During a Chemical Reaction

A team of NYU physicists has developed a method to monitor the properties of microscopic particles as they grow within a chemical reaction vessel, creating new opportunities to improve the quality and consistency of a wide range of industrial and consumer products. Their work, which appears as a cover story in the journal Soft Matter, offers benefits for commodities ranging from food and pharmaceuticals to perfumes and cosmetics.

Negatively Charged Molecules Control the Where, When, and How of Calcium Carbonate Formation

Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic scaffolds in which such crystals form guide crystallization by soaking up the calcium like an "ion sponge," according to new work in Nature Materials. Understanding the process better may help researchers develop advanced materials for energy and environmental uses, such as for removing carbon dioxide from the atmosphere.

MIT Researchers Develop Novel Approach for Nanoscale Resolution Microscopy of Large Biological Samples

Researchers from MIT have successfully discovered a technique to physically magnify tissue samples by implanting them in a polymer, which swells on addition with water to enable high-resolution images. Since the late 1500s when the first microscope was invented, scientists have been devising ways to study preserved tissues and cells in a better manner.

Scientists Discover Molecular Mechanisms Responsible for Adherens Junction Formation at the Nanoscale Level

Scientists at the Mechanobiology Institute (MBI) at the National University of Singapore (NUS) have discovered the molecular mechanisms responsible for the formation of the adherens junction at the nanoscale level. This research is published in Developmental Cell (Wu et al., Actin-delimited adhesion-independent clustering of E-cadherin forms the nanoscale building blocks of adherens junctions, Developmental Cell, 16 Jan 2015, doi.org/10.1016/j.devcel.2014.12.003).
