Spacecraft With Interstellar Medium Momentum Exchange Reactions: The potential and limitations of propellantless interstellar travel
All known interstellar transportation methods encounter monumental technological or engineering roadblocks, or even rely on speculative unknown science. In particular light of the recent public…
Measurement of bitumen viscosity in a room-temperature drop experiment: student education, public outreach and modern science in one
The slow flow of a viscous liquid is a thought-provoking experiment that challenges students, academics and the public to think about some fundamental questions in modern science. In the Queensland…
The Packing Landscapes of Quasi-One Dimensional Hard Sphere Systems
Packing Landscapes of Constrained Hard Sphere Fluids By Mahdi Zaeifi Yamchi When a liquid is cooled below its equilibrium freezing temperature, it becomes supercooled and the molecular motions slow…
Viscosity: From air to hot nuclei
After a brief review of the history of viscosity from classical to quantal fluids, a discussion of how the shear viscosity η of a finite hot nucleus is calculated directly from the width and energy…
Glassy Dynamics: From Millihertz to Terahertz
- Materials Science
In this article, we review broadband dielectric spectroscopy in supercooled liquids, in many cases covering more than 15 decades in frequency and a wide range of temperatures from the low-viscosity…
Fossil Time: oil, art and the body in the cosmopolitics of the Anthropocene
Fossil Time: oil, art and the body in the cosmopolitics of the Anthropocene – An artistic and theoretical investigation on fossil fuels, industrial agencies in nature and their reflections on social…
The chaotic dynamics of drilling
In the study of drilling dynamics, many investigations are limited to laboratory systems and simple mathematical models. Using field measurement data and a new dynamical model in a rotary steerable…

Mechanics of blast-induced traumatic brain injury in porcine brain tissue
A chronology of key events and quotes from the 12-month investigation into the deaths of six British servicemen and women at the hands of Islamist extremists in Iraq and Syria is revealed.
Using 20-million-year-old amber to test the super-Arrhenius behaviour of glass-forming systems.
- Physics, MedicineNature communications
Results from calorimetric and stress relaxation experiments using a 20-million-year-old Dominican amber deviate dramatically from the expectation of classical theory and are consistent with some modern ideas, in which the diverging timescale signature of complex fluids disappears below the glass transition temperature.
