TL;DR: Much research in emulsions can be applied to foam systems, however evidence would suggest foam systems are under a number of additional constraints, and the stability 'window' for particles is smaller, in terms of size and contact angle ranges.

TL;DR: In this review, the current understanding of food science is discussed, by considering established SCM methods as well as emerging techniques and theoretical approaches.
Abstract: Foods make up some of the most complex examples of soft condensed matter (SCM) with which we interact daily. Their complexity arises from several factors: the intricacy of components, the different aggregation states in which foods are encountered, and the multitude of relevant characteristic time and length scales. Because foodstuffs are governed by the rules of SCM physics but with all the complications related to real systems, the experimental and theoretical approaches of SCM physics have deepened our comprehension of their nature and behaviour, but many questions remain. In this review we discuss the current understanding of food science, by considering established SCM methods as well as emerging techniques and theoretical approaches. With their complexity, heterogeneity and multitude of states, foods provide SCM physics with a challenge of remarkable importance.

TL;DR: A new type of rigidity transition implicates the physical properties of the cells and resembles that of active particles jamming at a critical density—but the tissue density stays constant.
Abstract: Cells moving in a tissue undergo a rigidity transition resembling that of active particles jamming at a critical density—but the tissue density stays constant. A new type of rigidity transition implicates the physical properties of the cells.

TL;DR: In this article, the authors summarized what we know and what we need to learn about the science underlying these issues so that we are better prepared to tackle the next outbreak of COVID-19 or a similar disease.
Abstract: Flow physics plays a key role in nearly every facet of the COVID-19 pandemic. This includes the generation and aerosolization of virus-laden respiratory droplets from a host, its airborne dispersion and deposition on surfaces, as well as the subsequent inhalation of these bioaerosols by unsuspecting recipients. Fluid dynamics is also key to preventative measures such as the use of face masks, hand washing, ventilation of indoor environments and even social distancing. This article summarizes what we know and, more importantly, what we need to learn about the science underlying these issues so that we are better prepared to tackle the next outbreak of COVID-19 or a similar disease.

TL;DR: The mechanisms and theories suggested in the literature to explain the impact of oil on foam stability in the bulk and porous media are reviewed and various ideas on an improvement of foam stability and longevity in the presence of oil are presented.
