Actual Symmetry of Symmetric Adducts
This review discusses molecular adducts, whose composition allows a symmetric structure. Such adducts are popular model systems, as they are useful for analyzing the effect of structure on the property selected for study since they allow one to reduce the number of parameters. The main objectives of this discussion are to evaluate the influence of the surroundings on the symmetry of these adducts, steric hindrances within the adducts, competition between different noncovalent interactions responsible for stabilizing the adducts, and experimental methods that can be used to study the symmetry at different time scales. This review considers the following central binding units: hydrogen (proton), halogen (anion), metal (cation), water (hydrogen peroxide).

Marine Plastic Litter Reduction in Manila
Without coordinated intervention, the annual flow of plastics into the ocean is expected to nearly triple by 2040, from 11 million tons today to 29 million metric tons, globally. Manila Bay, situated in Manila, is where the challenges related to plastic pollution are of great importance nationally and, thus, make headlines globally, as plastic waste that is not properly managed has increased the economic and environmental effects of marine plastics. At the global governance forum on 2 March 2022, at the UN Environment Assembly in Nairobi, 175 countries endorsed a historic resolution to end plastic pollution and forge an international, legally binding agreement by the end of 2024. With this global and binding agreement, cities like Manila could properly enforce measures to end this plastic pollution—which needs the political will of the administrators and the participation of the relevant constituents.

Character Amnesia
Character amnesia is a phenomenon whereby experienced speakers of some East Asian languages forget how to write Chinese characters previously well known to them. The phenomenon is specifically tied to prolonged and extensive use of input methods, such as those that use romanizations of characters, and is documented to be a significant issue in China and Japan. Modern technology, such as mobile phones and computers, allows users to enter Chinese characters using their phonetic transcription without knowing how to write them by hand. Whether or not the phenomenon is as widespread or troubling as some have claimed is the subject of debate.

Vitamins in Treatment of Parkinson’s Disease
Parkinson’s disease (PD) is the second most common progressive neurodegenerative disorder after Alzheimer’s disease. Pathophysiologically, it is characterized by intracytoplasmic aggregates of α-synuclein protein in the Lewy body and loss of dopaminergic neurons from substantia nigra pars compacta and striatum regions of the brain. Although the exact mechanism of neurodegeneration is not fully elucidated, it has been reported that environmental toxins such as MPTP, rotenone, paraquat, and MPP+ induce oxidative stress, which is one of the causative factors for it. There is no complete cure. However, the indispensable role of oxidative stress in mediating PD indicates that antioxidant therapy could be a possible therapeutic strategy against the disease. The deficiency of vitamins has been extensively co-related to PD. Dietary supplementation of vitamins with antioxidant, anti-inflammatory, anti-apoptotic, and free radical scavenging properties could be the potential neuroprotective therapeutic strategy.

Ion-Imprinted Polymeric Materials
The introduction of selective recognition sites toward certain heavy metal ions (HMIs) is a great challenge, which has a major role when the separation of species with similar physicochemical features is considered. In this context, ion-imprinted polymers (IIPs) developed based on the principle of molecular imprinting methodology, have emerged as an innovative solution. Advances in IIPs have shown that they exhibit higher selectivity coefficients than non-imprinted ones, which could support a large range of environmental applications starting from extraction and monitoring of HMIs to their detection and quantification.

Agrivoltaics and Aquavoltaics
Agrivoltaics and aquavoltaics combine renewable energy production with agriculture and aquaculture. Agrivoltaics involves placing solar panels on farmland, while aquavoltaics integrates photovoltaic systems with water bodies and aquaculture. Benefits include dual land use, which allows farmers to produce clean energy while maintaining agricultural practices. They diversify renewable energy sources and reduce dependence on fossil fuels and greenhouse gas emissions. Solar panels in agrivoltaics provide shade, protect crops, reduce water needs, and increase yields. Challenges include high initial costs and limited accessibility, especially for small farmers. Integration with existing systems requires careful planning, considering irrigation, soil moisture, and crop or fish production. Maintenance and cleaning present additional challenges due to dust, debris, and algae. Policy and regulatory frameworks must support implementation, including incentives, grid integration, land use regulations, and conservation.

In Vitro Embryogenesis and Gastrulation Using Stem Cells
During early mammalian embryonic development, fertilized one-cell embryos develop into pre-implantation blastocysts and subsequently establish three germ layers through gastrulation during post-implantation development. Stem cells have emerged as a powerful tool to study embryogenesis and gastrulation without the need for eggs, allowing for the generation of embryo-like structures known as synthetic embryos or embryoids. These in vitro models closely resemble early embryos in terms of morphology and gene expression and provide a faithful recapitulation of early pre- and post-implantation embryonic development. Synthetic embryos can be generated through a combinatorial culture of three blastocyst-derived stem cell types, such as embryonic stem cells, trophoblast stem cells, and extraembryonic endoderm cells, or totipotent-like stem cells alone.

Reducing Phosphorus Pollution of Freshwater Fish Farms
Water soluble phosphorus, uneaten feed, feces, and metabolic waste from farmed fish increase phosphorus concentrations in adjacent waters. In open freshwater fish farms, in particular, the effects can be more immediate, as excess phosphorus is introduced directly into ecosystems. Several intestinal enzymes, transporters, and regulating factors have been implicated in farmed fish dietary phosphorus retention. To reduce phosphorus pollution from open flow fish farms, a thorough understanding of the processes that affect nutrient retention and absorption, as well as the impact of dietary factors, anti-nutritional substances, and intestinal morphology, is required.

Phage Therapy for Crops
Phage therapy consists of applying bacteriophages, whose natural function is to kill specific bacteria. Bacteriophages are safe, evolve together with their host, and are environmentally friendly. The indiscriminate use of antibiotics and salt minerals (Zn2+ or Cu2+) has caused the emergence of resistant strains that infect crops, causing difficulties and loss of food production. Phage therapy is an alternative that has shown positive results and can improve the treatments available for agriculture.

Cr-free High-Temperature Water-Gas Shift Catalysts
Replacement of toxic Cr in the industrial Fe-oxide based High-Temperature Water-Gas Shift (HT-WGS) catalysts has been the focus of intense research in the past decades. In the current manuscript, we examine the promotion effect of Ca, Ni, Co and Ge as possible Cr substituents, and Ca and Ni are found to improve catalysts performance relative to Cr promotion. The current study, besides finding two promising Cr substitutes (Ca and Ni) for the HT-WGS reaction catalyst, also emphasizes on the qualities a promoter must possess to become a suitable substitution of Cr. The remarkable performance of Ca and Ni promoters are related to their ability to stabilize the surface area of the respective catalysts by making partial or complete solid solution with the bulk Fe-oxide phase and by promoting highly redox Cu0-FeOx interfacial sites on the catalyst surface. The poorer performance exhibited by Co and Ge promoters is related to the lack of their ability to promote the highly active Cu0-FeOx interfacial sites along with inability of Co to stabilize the surface area. All the promoters follow a redox type mechanism for the HT-WGS reaction.
