A study on the metallicity gradients in the galactic disk using open clusters

Frontiers in Astronomy and Space Sciences
We study the metallicity distribution and evolution in the galactic disk based on the largest sample of open star clusters in the galaxy. From the catalog of 1,879 open clusters in the range of galactocentric distance (RGC) from 4 to 20 kpc, we ...

Improved taxonomic and gene sampling advance the knowledge of deep relationships within Macrodasyida (Gastrotricha)

Cladistics, EarlyView.
Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.

Questions Should Have Answers

European Journal of Philosophy, EarlyView.
ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...

Winter‐active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta‐solenoid fold

The FEBS Journal, EarlyView.
Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.
