The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday.
An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperilling marine life, on which billions of people depend for their nutrition and livelihood.
“If science is the constellation of facts, theories, and methods collected in current texts, then scientists are the men who, successfully or not, have striven to contribute one or another element to that particular constellation. Scientific development becomes the piecemeal process by which these items have been added singly and in combination, to the ever growing stockpile that constitutes scientific technique and knowledge. And history of science becomes the discipline that chronicles both these successive increments and the obstacles that have inhibited their accumulation. Concerned with scientific development, the historian then appears to have two main tasks. On the one hand, he must determine by what man and at what point in time each contemporary scientific fact, law, and theory was discovered or invented. On the other, he must describe and explain the congeries of error, myth, and superstition that have inhibited the more rapid accumulation of the constituents of the modern science text.”—

Global warming is expected to have far-reaching, long-lasting and, in many cases, devastating consequences for planet Earth. For some years, global warming — the gradual heating of Earth’s surface, oceans and atmosphere — was a topic of heated debate in the scientific community.
But the overwhelming consensus of researchers today is that global warming is real and is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere.
Additionally, global warming is having a measurable effect on the planet right now. [ Increase in average temperatures, extreme weather events, shift in climate patterns, snow and ice, rising sea levels, ocean acidification, plant and animal impacts, social impacts] …
So how does this work? The nanoparticles are given either a positive or negative charge via their coating. When the solutions are mixed, the positive and negative charges attract to each other to form a network. Once injected into the skin, this network holds the nanoparticles together so that they don’t disperse throughout the body. The nano-network is created to be porous, allowing blood and blood sugar to reach the nanoparticle cores.
The injectable nanoparticles are mixed with insulin, modified dextran and glucose oxidase enzymes. Under high glucose levels, these enzymes convert glucose to gluconic acid, breaking down the modified dextran and releases insulin. The remaining gluconic acid and dextran dissolve in the body.
