Microbes for biofuel: a cleaner way to unlock their energy

Algae and photosynthetic bacteria hold a hidden treasure – fat molecules known as lipids – which can be converted to renewable biofuels. Such microorganisms offer an attractive alternative to the unsustainable use of petroleum-based fossil fuels, as well as biofuel sources requiring arable cropland.

Billions at Risk of ‘Water Insecurity’

Who owns the rights to the melting Arctic?

Still, the hope for a Northwest Passage lingers and has become central to a key international debate heating up over the Arctic north. If climate change and global warming are real -- and there's currently little doubt over that-then it stands to reason that the ice covering Arctic waterways will decrease in coming decades, presenting fewer navigational problems for shipping. If the ice recedes -- and few experts expect it will do so year-round-cargo shipping times and distances could, the thinking goes, be cut: A 12,400-mile voyage from Japan to England by way of the Panama Canal could be shortened to less than 8,700 miles using the Northwest Passage, saving 14 days and costs.
