Atriplex Portulacoides as Functional Food
The halophyte Atriplex portulacoides (syn. Halimione portulacoides) occurs in habitats that are exposed to seawater inundations, and shows biochemical adaptations to saline and oxidative stresses. Its composition includes long chain lipids, sterols, phenolic compounds, glutathione, carotenoids,and micronutrients such as Fe, Zn, Co and Cu. The productivity of A. portulacoides in natural environments, and its adaptability to non-saline soils, make it a potential crop of high economic interest. This plant is suitable to be exploited as a functional food that is potentially able to reduce oxidative stress and inflammatory processes in humans and animals. This plant offers a valuable example of valorisation of the biodiversity for promoting the sustainability and diversification in agriculture.

Agro-Waste Management
It is urgent that we increase global food production to support population growth. Food production requires significant resources, amongst them water and energy. Therefore, any losses of food or other agricultural products also means a waste of water and energy resources. A significant amount of these losses occurs during the postharvest stage, primarily during processing and storage. This is considered avoidable food waste. The water-energy-waste nexus (WEW), and its relationship to food production, needs to be investigated from a circular bioeconomy lens. Furthermore, alternative uses of the wastes should be investigated.

Tomato Fruit Set and Parthenocarpy
Fruit set is the earliest phase of fruit growth and represents the onset of ovary growth after successful fertilization. Environmental conditions can negatively affect fruit set and final productivity. In parthenocarpy, fruit formation is less affected by environmental factors because it occurs in the absence of pollination and fertilization, making parthenocarpy a highly desired agronomic trait. Elucidating the genetic program controlling parthenocarpy, and more generally fruit set, may have important implications in agriculture, considering the need for crops to be adaptable to climate changes. Several phytohormones play an important role in the transition from flower to fruit. Further complexity emerges from functional analysis of floral homeotic genes. Some homeotic MADS-box genes are implicated in fruit growth and development, displaying an expression pattern commonly observed for ovary growth repressors.

Application of Plant Viruses
Plant-based nanotechnology programs using virus-like particles (VLPs) and virus nanoparticles (VNPs) are emerging platforms that are increasingly used for a variety of applications in biotechnology and medicine. Tobacco mosaic virus (TMV) and potato virus X (PVX), by virtue of having high aspect ratios, make ideal platforms for drug delivery. TMV and PVX both possess rod-shaped structures and single-stranded RNA genomes encapsidated by their respective capsid proteins and have shown great promise as drug delivery systems. Cowpea mosaic virus (CPMV) has an icosahedral structure, and thus brings unique benefits as a nanoparticle.

Sparrow
Sparrows are a family of small passerine birds. They are also known as true sparrows, or Old World sparrows, names also used for a particular genus of the family, Passer. They are distinct from both the American sparrows, in the family Passerellidae, and from a few other birds sharing their name, such as the Java sparrow of the family Estrildidae. Many species nest on buildings and the house and Eurasian tree sparrows, in particular, inhabit cities in large numbers, so sparrows are among the most familiar of all wild birds. They are primarily seed-eaters, though they also consume small insects. Some species scavenge for food around cities and, like gulls or rock doves will happily eat virtually anything in small quantities.

Cat Body-type Mutation
Cats, like all living organisms, occasionally have mutations that affect their body type. Sometimes, these cat body-type mutations are striking enough that humans select for and perpetuate them. This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form. This article gives a selection of cat body type mutant alleles and the associated mutations with a brief description.

AMPs Nisin and Food Preservation
This study reports the application of antimicrobial peptides (AMPs) in food preservation because of their ability to inactivate spores and spore-forming bacteria. The review focused more on nisin, which is one of the sufficiently characterised AMPs for use in the food industry. The mechanisms of spore-forming bacteria inactivation, the effectiveness of using nisin AMP alone and the synergistic effect of combining AMPs with other non-thermal emerging technologies were explored.

Recursion Predicts Covid-19 Trajectories
Modulated recurrence model predicts Covid-19 trajectory in multiple countries.  Wave action at 14-week intervals correlates with case numbers, while predicting future growth rate surges. Graphs of total Covid-19 case numbers in many countries now show long-period wave action.  Simulations using a sine modulated time-delay recurrence equation not only correlate with case data but also proves a π-commensurate wave period of 26 weeks.  When the slope of geometric growth exceeds arithmetic growth, a periodic wave launches in the population with all the dynamics of a damped oscillation.  Recursive simulation generates trajectories that predict future wave peak times and amplitudes.  Data from USA, Canada, UK, Germany, India and Australia are studied in this research.  In all cases, Covid-19 trajectories around the world show the common feature of periodic oscillations as case numbers increase.  Discovery of repeatable Covid-19 growth dynamics suggests a common invariant mechanism of virus propagation, irrespective of country.

Microbial Communities
Although ice-free areas cover only about 0.1% of Antarctica and are characterized by harsh environmental conditions, these regions provide quite diverse conditions for the soil-forming process, having various physical and geochemical properties, and also assuring different conditions for living organisms. This study is aimed to determine existing soil microbial communities, their relationship with soil parameters and the influence of anthropogenic activity in Larsemann Hills, Eastern Antarctica. The soil microbiome was investigated at different locations using 16S rRNA gene pyrosequencing. The taxonomic analysis of the soil microbiomes revealed 12 predominant bacterial and archaeal phyla—Proteobacteria, Actinobacteria, Acidobacteria, Chloroflexi, Gemmatimonadetes, Verrucomicrobia, Planctomycetes, Bacteroidetes, Armatimonadetes, Firmicutes, Cyanobacteria, Thaumarchaeota. Some specific phyla have been also found in sub-surface horizons of soils investigated, thus providing additional evidence of the crucial role of gravel pavement in saving the favorable conditions for both soil and microbiome development. Moreover, our study also revealed that some bacterial species might be introduced into Antarctic soils by human activities. We also assessed the effect of different soil parameters on microbial community in the harsh environmental conditions of Eastern Antarctica. pH, carbon and nitrogen, as well as fine earth content, were revealed as the most accurate predictors of soil bacterial community composition.

Misregulation of Wnt Signaling Pathways
Wnt signaling pathways constitute a group of signal transduction pathways that direct many physiological processes, such as development, growth, and differentiation. Dysregulation of these pathways is thus associated with many pathological processes, including neurodegenerative diseases, metabolic disorders, and cancer. At the same time, alterations are observed in plasma membrane compositions, lipid organizations, and ordered membrane domains in brain and metabolic diseases that are associated with Wnt signaling pathway activation.
