Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria. Dramatic progress has been made over the last decad...
Protein's strength lies in h-bond cooperation
CAMBRIDGE, Mass. Researchers in Civil and Environmental Engineering at MIT reveal that the strength of a biological material like spider silk lies
in the specific geometric configuration of structural proteins, which have small clusters of weak hydrogen bonds that work cooperatively to resist for...
The origin of the brain lies in a worm
The rise of the central nervous system (CNS) in animal evolution has puzzled scientists for centuries. Vertebrates, insects and worms evolved from the same ancestor, but their CNSs are different and were thought to have evolved only after their lineages had split during evolution. Researchers from ...
Key to acute lung injury lies in Ang2 protein
Acute lung injury caused by cell death, high and potentially toxic concentrations of oxygen (hyperoxia), and the resulting excess fluid in the lungs (pulmonary edema), may be controlled by modulating levels of the angiopoietin2 (Ang2) protein, researchers at Yale School of Medicine report in the No...
