Rolling with the punches: How mantis shrimp defend against high-speed strikes      (via sciencedaily.com)     Original source 

Mantis shrimp are small creatures known for their superlatives. Their eyes have 12 to 16 different color receptors, versus our own three, and can detect the polarization of light. Their punches are famously fast, accelerating on par with a 22-caliber bullet. They use these strikes on prey, predators and competitors alike.

New Rhizobia-diatom symbiosis solves long-standing marine mystery      (via sciencedaily.com)     Original source 

Scientists have discovered a new partnership between a marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. The newly-discovered bacterial symbiont is closely related to the nitrogen-fixing Rhizobia which live in partnership with many crop plants and may open up new avenues to engineer nitrogen-fixing plants.

Astrophysicists discover a novel method for hunting the first stars      (via sciencedaily.com)     Original source 

A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.

An epigenome editing toolkit to dissect the mechanisms of gene regulation      (via sciencedaily.com)     Original source 

A recent study led to the development of a powerful epigenetic editing technology. The system unlocks the ability to precisely program chromatin modifications at any specific position in the genome, to understand their causal role in transcription regulation. This innovative approach will help to investigate the role of chromatin modifications in many biological processes, and to program desired gene activity responses, which may prove useful in disease settings.

An adjuvant made in yeast could lower vaccine cost and boost availability      (via sciencedaily.com)     Original source 

Adjuvants make vaccines more effective, though one of the best is an expensive extract from the soap bark tree. To lower the cost and avoid the laborious extraction process from bark, synthetic biologists introduced 38 separate genes into yeast to recreate the synthesis of the active molecule, a complex chemical, QS-21, that has a terpene core and numerous sugars. This may be the longest biosynthetic pathway ever inserted into yeast.
