A photosynthetic organism's 'Water World'
Following the path of radicals and being able to identify many damaged residues because of incredibly accurate, expeditious and sensitive mass spectrometry, three scientists studied the great granddaddy of all photosynthetic organisms -- a strain of cyanobacteria -- to develop the first experimental map of that organism's water world.

Unlocking the secrets of Ebola
Scientists have identified a set of biomarkers that indicate which patients infected with the Ebola virus are most at risk of dying from the disease. The results come from one of the most in-depth studies ever of blood samples from patients with Ebola. Researchers found 11 biomarkers that distinguish fatal infections from non-fatal ones and two that, when screened for early upon symptom onset, accurately predict which patients are likely to die.

How Snapdragons keep their color: Signposting trick reveals evolutionary mechanism
A study of the colour patterns among wild flowers in a mountain valley has yielded a clue about how nature controls fundamental evolutionary change in all species.

Passenger pigeon genome shows effects of natural selection in a huge population
The passenger pigeon is famous for the enormity of its historical population and for its rapid extinction in the face of mass slaughter by humans. Yet it remains a mystery why the species wasn't able to survive in a few small populations. One theory, consistent with the findings of a new study, suggests that passenger pigeons were well adapted to living in huge flocks, but poorly adapted to living in smaller groups.

Paraplegic rats walk and regain feeling after stem cell treatment
Paralyzed rats implanted with engineered tissue containing human stem cells were able to walk independently and regained sensory perception in their hind legs and tail. The implanted rats also show some degree of healing in their spinal cords. The research demonstrates the great potential of stem cells to treat spinal cord injury.

Bacterium in a beetle makes it a leaf-eater
A leaf-eating beetle has evolved a symbiotic relationship that allows the insect to break down pectin. The findings on the novel function of the bacterium, which has a surprisingly tiny genome -- much smaller than previous reports on the minimum size required for an organism not subsisting within a host cell.

How the songbird changes its tune
Researchers have shown how the Bengalese finch, a domesticated songbird, can learn to tweak its song in specific ways depending on context, which could shed light on how the human brain learns to apply different rules depending on the situation, and have implications for understanding human language and movement disorders.
