Producing biodegradable plastic just got cheaper, greener
Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives. And yet, PLA is not yet considered a full alternative to traditional petroleum-based plastics, as it is costly to produce. Researchers now present a way to make the PLA production process more simple and waste-free.

Mechanism of biological multi-fuel engine
Researchers have constructed the atomic model structure of the protein complex that corresponds to the stator (stationary part of a motor that surrounds the rotating part of a motor) of the E. coli flagellar motor for the first time by molecular simulation based on previously published experimental data, and elucidated the mechanism by which ions, including hydrogen ions (protons), are transferred through the stator.

Learning from biology to accelerate discovery
A new review paper explores the strategies nature employs to achieve different functions and the mechanics at play within those functions. Surveying everything from sea cucumbers and Venus flytraps to human muscles and trees, the review paper broadly explores the strategies that biology employs to create different functions and the mechanics at play within those functions.

'Bee soup' could help understand declines, test remedies
It may sound counter-intuitive, but crushing up bees into a 'DNA soup' could help conservationists understand and even reverse their decline, according to scientists. New research shows that collecting wild bees, extracting their DNA, and directly reading the DNA of the resultant 'sop' could finally make large-scale bee monitoring programs feasible. This would allow conservationists to detect where and when bee species are being lost and whether conservation interventions are working.

Stopping Candida in its tracks
Scientists are one step closer to understanding how a normally harmless fungus changes to become a deadly infectious agent.

'Map Of Life' predicts ET. (So where is he?)
The author of a new study of evolutionary convergence argues that the development of life on Earth is predictable, meaning that similar organisms should therefore have appeared on other, Earth-like planets by now. So why do we appear to be all alone in the universe?

Infection with Wolbachia bacteria curbs fighting among fruit flies
Male fruit flies infected with the bacterium, Wolbachia, are less aggressive than those not infected, according to research. This is the first time bacteria have been shown to influence aggression.

Unexpected enzyme may resurrect roses' fading scents
Researchers working with roses have identified an enzyme which plays a key role in producing the flowers' sweet fragrances.

The sting in dengue's tail
Scientists have identified how small changes in dengue's viral genome can affect the virus' ability to manipulate human immune defenses and spread more efficiently.

Prion trials and tribulations: Finding the right tools and experimental models
Prions are fascinating, enigmatic, and might teach us not only about rare prion diseases like Creutzfeld-Jakob disease, mad cow disease, or scrapie, but also about other more common neurodgenerative diseases. Two studies report progress with novel tools and paradigms to study prion disease.
