Engineered microbe may be key to producing plastic from plants

With a few genetic tweaks, a type of soil bacteria with an appetite for hydrocarbons shows promise as a biological factory for converting a renewable—but frustratingly untapped—bounty into a replacement for ubiquitous ...

Sustainable 'plastics' are on the horizon

A new Tel Aviv University study describes a process to make bioplastic polymers that don't require land or fresh water—resources that are scarce in much of the world. The polymer is derived from microorganisms that feed ...

Heavy oils and petroleum coke raising vanadium emissions

Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen ...

Appendages help microbes survive harsh conditions

The most ancient kinds of microbes on Earth often have a special filament lining their surfaces. Scientists are discovering that these structures can play a variety of roles in helping microorganisms survive the most hostile ...

How will climate policy affect energy access goals?

Stringent climate policies would increase the cost of fossil fuels, including those used for the cleaner burning stoves (such as kerosene, liquefied petroleum gas, electricity, and piped gas) that are slowly replacing traditional ...
