Mars has an underground lake beneath the polar cap. And the Curiosity rover has discovered complex organic molecules on Mars. Organic molecules are considered the building blocks of life. Another sensational discovery on Mars is the methane gas that has been detected in the Martian atmosphere. The source of methane could be either geological or most excitingly, biological.

Can you imagine a paper made of stone instead of trees? Stone paper is made of stone particles and non-toxic resin. It produces zero waste and requires no water during its production, and has a much smaller carbon footprint compared to traditional tree-based papers. Stone paper was firstly launched to the market in 2008. Currently, stone paper accounts for 1% of all paper sales globally. When compared with regular pulp paper, stone paper is superior in several ways. For example, it is completely waterproof and has higher resistance to tearing.

Another essential feature of the stone paper is its higher resistance to tearing compared to regular pulp paper. This makes it ideal for packing, and for replacing the traditional pulp-based paper bags, which can’t carry much weight and can be reused very few times. These improved bags made of stone paper can be used at trade shows, supermarkets and department stores instead of tree-based paper or plastic bags.
