Scientists discovered a dinosaur fossil with feathers so well-preserved that they were able to see the feathers' microscopic color-bearing structures. By comparing the shapes of those feather structures with the structures in modern bird feathers, they're able to infer that the new dino, Caihong juji ('rainbow with the big crest') had iridescent rainbow feathers like a hummingbird.

Unexpected environmental source of methane discovered

Added: 15.01.2018 12:05 | 1 views | 0 comments

#zrodlo

Roughly 10 percent of nitrogen-fixing microorganisms contain the genetic code for manufacturing a back-up enzyme, called iron iron-only nitrogenase, to do their job. New research reveals that this enzyme allows these microorganisms to convert nitrogen gas to ammonia and carbon dioxide into methane at the same time. This enzymatic pathway is a previously unknown route for the natural biological production of methane.

#zrodlo

How biological membranes -- e.g. the plasma membrane of animal cells or the inner membrane of bacteria -- fluctuate over time is not easy to understand. Researchers propose a new theory elucidating the dynamics of such membranes when they are embedded in polymer networks. In a new study they demonstrate that the dynamics of membrane undulations inside such a structured medium are governed by distinctive, anomalous power laws.
