Approximately 74 thousand years ago (ka), the Toba caldera erupted in Sumatra. Since the magnitude of this eruption was first established, its effects on climate, environment and humans have been debated. Here we describe the...
Computing the motor torque of Escherichia coli.
The rotary motor of bacteria is a natural nano-technological marvel that enables cell locomotion by powering the rotation of semi-rigid helical flagellar filaments in fluid environments. It is well known that the motor operates...

Adaptive immune responses are initiated by triggering of the T cell receptor. Single-molecule imaging based on total internal reflection fluorescence microscopy at coverslip/basal cell interfaces is commonly used to study this...
Beyond Bones: Applying Bioactive Glasses to Long-Term Drug Delivery
Ever since bioactive glasses were discovered in 1969, they have traditionally been used for bone repair and regeneration. However, they carry other useful purposes as well, and have shown they have potential in long-term drug...

Electroosmotic flow reversal outside glass nanopores.
We report observations of a striking reversal in the direction of electroosmotic flow (EOF) outside a conical glass nanopore as a function of salt concentration. At high ionic strengths (>100 mM), we observe EOF in the expected...
Pattern formation in drying blood drops.
Patterns in dried droplets are commonly observed as rings left after spills of dirty water or coffee have evaporated. Patterns are also seen in dried blood droplets and the patterns have been shown to differ from patients...

Impact of glass shape on time taken to drink a soft drink
BACKGROUND: Glassware design may affect drinking behaviour for alcoholic beverages, with glass shape and size influencing drinking speed and amount consumed. Uncertainty remains both about the extent to which these effects are...
Predicting Crystallization of Amorphous Drugs with Terahertz Spectroscopy.
Glass-Transition Temperature of the β-Relaxation as the Major Predictive Parameter for Recrystallization of Neat Amorphous Drugs.

Recrystallization of amorphous drugs is currently limiting the simple approach to improve solubility and bioavailability of poorly water-soluble drugs by amorphization of a crystalline form of the drug. In view of this...
Linking particle properties to dense suspension extrusion flow characteristics using discrete element simulations
Extrusion is a widely used process for forming suspensions and pastes into designed shapes, and is central to the manufacture of many products. In this article, the extrusion through a square-entry die of non-Brownian spheres...
Image Encoding Using Multi-Level DNA Barcodes with Nanopore Readout.
Deoxyribonucleic acid (DNA) nanostructure-based data encoding is an emerging information storage mode, offering rewritable, editable, and secure data storage. Herein, a DNA nanostructure-based storage method established on a...
Evaluating Stiffness of Fibreglass and Thermoplastic Splint Materials and Inter-fragmentary Motion in a Canine Tibial Fracture Model.
