When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions.
There are several processes that plants and animals or their parts can be preserved.
A student in Sweden made the stunning discovery while examining seemingly innocuous fossilised microbes dating from 1.6 billion years ago taken from rocks in Chitrakoot, central India.
“What I could see was the fossils were really, really big compared to the bacterial fossils surrounding them.
Pyrolysis bio-oil is produced by rapidly heating the forest residues in an oxygen-free environment and then rapidly cooling the ...
A third of oil reserves, half of gas reserves and over 80% of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target ...
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.
The heat generated by burning a fossil fuel is surpassed within a few months by the warming caused by the release of its carbon dioxide into the atmosphere, a new study says. Weaning cars and trucks off of gasoline and diesel made from fossil fuels is a difficult task.
