Are bacteria making you hungry? | e! Science News

Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals.
sferrebenedicto's insight:

"Bacteria both recognize and synthesize neuroendocrine hormones," Norris et al. write.

New insights into how plants grow in response to light, water and gravity

New insights into how plants grow in response to light, water and gravity | The state of the sciences | Scoop.it
Elementary school students often learn that plants grow toward the light. This seems straightforward, but in reality, the genes and pathways that allow plants to grow and move in response to their environment are not fully understood.

Futurity.org – Protein engineers unlock catalyst’s options | The state of the sciences | Scoop.it
Research news from leading universities
sferrebenedicto's insight:

Quote: "

Protein engineers have tapped into a hidden talent of one of nature’s most versatile catalysts. The enzyme cytochrome P450 is nature’s premier oxidation catalyst—a protein that typically promotes reactions that adds oxygen atoms to other chemicals.

Now, researchers have engineered new versions of the enzyme, unlocking its ability to drive a completely different and synthetically useful reaction that does not take place in nature."

Plant Cell: The Moss miR156-miR390-tasiRNA Network

Plant Cell: The Moss miR156-miR390-tasiRNA Network | The state of the sciences | Scoop.it

"A gene regulatory network controlled by miR156, miR390, and their targets controls developmental change in P. patens. The broad outlines and regulatory logic of this network are conserved in flowering plants, albeit with some modifications. Partially conserved small RNA networks thus influence developmental timing in plants with radically different body plans."


Via Mary Williams
sferrebenedicto's insight:

A microRNA that affects developmental timing in flowering plants, and its network seems universally conserved in land plant. Awesome!

Redrawing the Tree of Life – Phenomena: The Loom

Redrawing the Tree of Life – Phenomena: The Loom | The state of the sciences | Scoop.it
sferrebenedicto's insight:

Quote: "Our ancestry runs through the ancestry of archaea. And by looking at archaea, we may be able to discern some key steps on the path to our eukaryote cells. Our cells have skeletons, for example: molecular scaffolding that give them structure and which they can reassemble to travel from one place to another. Recently, scientists have discovered archaea with two components of our skeleton:actin and tubulin. And in the new journal eLife, Corey Nislow and his colleagues report the discovery of the same coiled-up chromatin in archaea."
