In the Name of Allah---the Most Beneficent, the Most Merciful. Abstract The term  “methane bomb”  refers to the hypothesized sudden and massive release of methane (CH₄) from Arctic permafrost and oceanic methane hydrates due to rising global temperatures. Methane is a potent greenhouse gas, with a global warming potential more than 80 times that of CO₂ over a 20-year period. This paper reviews the    scientific  basis, current evidence, and potential consequences of a large-scale methane release, along with the implications for climate feedback loops and global mitigation efforts. 1. Introduction Methane (CH₄) is the second most significant anthropogenic greenhouse gas after carbon dioxide (CO₂). While it has a relatively short atmospheric lifetime of about 12 years, its radiative forcing capacity makes it a key driver of near-term climate change. A particularly alarming hypothesis is the “methane bomb”: a scenario in which massive stores of methane, currently l...

In the Name of Allah---the Most Beneficent, the Most Merciful. Abstract The  zinc spark  is a brief, coordinated exocytotic release of zinc ions from the mammalian oocyte at the moment of egg activation (fertilization or parthenogenetic activation). First described in 2011, zinc sparks are now recognized as a conserved feature of mammalian fertilization, linking sperm-triggered calcium signaling to downstream biochemical and physicochemical events required for the egg-to-embryo transition. Zinc sparks reduce intracellular zinc, alter the zona pellucida, and correlate with embryo developmental potential—making them both mechanistically important and clinically promising as non-invasive biomarkers in assisted reproduction. ( PMC ) Introduction In modern embryology, the  zinc spark  is increasingly described as a  biochemical signature of the beginning of life . At the precise moment when a sperm successfully activates the egg, a burst of zinc ions is released in a...
