Astrooceanography
Astrooceanography is the study of oceans outside planet Earth. Unlike other planetary sciences like astrobiology, astrochemistry and planetary geology, it only began after the discovery of underground oceans in Saturn's Titan and Jupiter's Ganymede. This field remains speculative until further missions reach the oceans beneath the rock or ice layer of the moons. There are many theories about oceans or even ocean worlds of celestial bodies in the Solar System, from oceans made of diamond in Neptune to a gigantic ocean of liquid hydrogen that may exist underneath Jupiter's surface. Early in their geologic histories, Mars and Venus are theorized to have had large water oceans. The Mars ocean hypothesis suggests that nearly a third of the surface of Mars was once covered by water, and a runaway greenhouse effect may have boiled away the global ocean of Venus. Compounds such as salts and ammonia dissolved in water lower its freezing point so that water might exist in large quantities in extraterrestrial environments as brine or convecting ice. Unconfirmed oceans are speculated beneath the surface of many dwarf planets and natural satellites; notably, the ocean of the moon Europa is estimated to have over twice the water volume of Earth. The Solar System's giant planets are also thought to have liquid atmospheric layers of yet to be confirmed compositions. Oceans may also exist on exoplanets and exomoons, including surface oceans of liquid water within a circumstellar habitable zone. Ocean planets are a hypothetical type of planet with a surface completely covered with liquid. Astrooceanography is closely related to Astrobiology, as oceans are expected to have higher chances to house simple forms of life.

CRISPR, Livestock, Sustainable Food Production
The growing demand for animal source foods to feed people has been pushing the livestock industry to increase productivity, a tendency that will continue throughout this century. The challenge for the coming years is to increase the food supply to ensure equity in access to high quality food, while maintaining global sustainability including combating climate change, avoiding deforestation, and conserving biodiversity, as well as ensuring animal health and welfare. The question is, how do we produce more with less? Classical methods to enhance livestock productivity based on the improvement of animal health, nutrition, genetics, reproductive technologies and management have made important contributions; however, this is not going to be enough and thus disruptive approaches are required. Genome editing with CRISPR may be a powerful contributor to global livestock transformation.

Neuroarchaeology
Neuroarchaeology refers to a field of study that records neuroscientific history through archaeological methods of investigation. The term was first suggested and thus coined by Colin Renfrew and Lambros Malafouris first individually in 2004 and then collaboratively in 2008.It is a combination of the words "neuro-" from 'neuroscience' indicating its connection with the brain sciences and "archaeology" meaning study of human history and prehistory through excavations and other tools. Significant leaps in brain and cognitive sciences in the 21st century have opened up new areas of partnership between archaeology and neuroscience. This collaboration can help an archaeologist figure out biological and neural substrates of human cognitive abilities present in the archaeological objects. The knowledge of neuroscience can also be applied to critically review and challenge existing theories and assumptions about the inception of modern human cognition. The term implies a new area of research that could investigate issues relating to the collaboration between the brain and culture over the long term development of humans. So far, the goals of neuroscience and archaeology are the same- to understand human nature. But their disciplinary approaches diverge significantly. Neuroarchaeology aims at building the analytical bridge between brain and culture ""by putting material culture, embodiment, time and long-term change at centre stage in mind".

Bivalve Shells’ Waste Valorization
Bivalve shells are mainly formed by CaCO3, giving them the potential to become a promising secondary raw material for several applications, from a circular economy perspective. All the examples reported aimed to map the principal opportunities of mollusk shells waste recovery, in order to implement a circular blue-economy model and provide more sustainable and responsible production systems.

Global Plastic Waste is Increasing
Global plastic waste is increasing rapidly. In general, densely populated regions generate tons of plastic waste daily, which is sometimes disposed of on land or diverged to sea. Most of the plastics created in the form of waste have complex degradation behavior and are non-biodegradable by nature. These remain intact in the environment for a long time span and potentially originate complications within terrestrial and marine life ecosystems. The strategic management of plastic waste and recycling can preserve environmental species and associated costs.

Bioaccumulation of Fluoride and Its Microbially Assisted Remediation
Fluoride is widely found in soil–water systems due to anthropogenic and geogenic activities that affect millions worldwide. Fluoride ingestion results in chronic and acute toxicity, including skeletal and dental fluorosis, neurological damage, and bone softening in humans.

Driving Cycles for Estimating Vehicle Emission Levels
Standard driving cycles (DCs) and real driving emissions (RDE) legislation developed by the European Commission contains significant gaps with regard to quantifying local area vehicle emission levels and fuel consumption (FC). The aim of this paper was to review local DCs for estimating emission levels and FC under laboratory and real-world conditions. This review article has three sections.

Brown Lake (Stradbroke Island)
Brown Lake (Bummeria) is a perched lake on North Stradbroke Island, in South-East Queensland, Australia. The ecosystem is an example of a coastal non-floodplain sand lake and is characterised by acidic water, nutrient-poor and sandy soil, shrub-like vegetation and wet heathland. Brown Lake is of geographical significance, possessing ecological value. The geomorphology of the ecosystem is representative of the unique parabolic dune ridge systems that formed during the Pleistocene epoch. As a perched lake, the hydrological operations of Brown Lake are highly diverse and complex. The lake is also of cultural significance to the Aboriginal population of North Stradbroke Island, the Quandamooka people, as they possess a spiritual and physical relationship with the ecosystem. The indigenous population care for and protect the landscape, sharing traditional environmental management knowledge. Brown Lake’s cultural heritage and ecological value, along with the environmental damage associated with tourism, has led to increased conservation. The Queensland Government and the Quandamooka Yoolooburrabee Aboriginal Corporation (QYAC) have proposed an improved environmental management plan, combining traditional and contemporary management practices.

Shellac and Its Potential in the Packaging Application
Shellac, an insect-derived material, has received the least attention due to its scarcity in south Asia. Currently, Shellac is used in various applications, such as furniture polish, glazing agent for candies and pharmaceutical pills, coating on fruits to increase shelf life, primers, smart sensor, 3D printing, and green electronic. However, the limitations of Shellac such as: brittleness with time, self-esterification, low transparency, solubility in alkaline medium and in most organic solvents have limited its usage in the packaging application. Many of these problems can be improved by physical blending or chemical reaction with other materials to make Shellac more durable, impede self-esterification, and facilitate the film-forming ability, which suggests the potential usage of Shellac in packaging applications.
