How a soil microbe could rev up artificial photosynthesis
When it comes to fixing carbon, plants have nothing on soil bacteria that can do it 20 times faster. The secret is an enzyme that 'juggles' reaction ingredients. Scientists hope to optimize this process for producing fuels, antibiotics and other products from CO2.

Anatomical study confirms: Harbor seals are good at learning calls
Harbor seals may sound different than expected from their body size. Is this ability related to their vocal talents or is it the result of an anatomical adaptation? An international team has now investigated the vocal tracts of harbor seals, which matched their body size. This means that harbor seals are capable of learning new sounds thanks to their brains rather than their anatomy.

Unlocked enzyme structure shows how strigolactone hormone controls plant growth
As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond to the environment and integrate the signals from outside with endogenous developmental programs. New research unravels the underlying mechanism of protein targeting and destruction in a specific plan
