Early evolutionary history of the seed
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Candidate Main-belt Asteroids for Surface Heterogeneity
Large terrestrial bodies in our solar system like the Earth, Mars, Mercury, and the Moon exhibit geologically complex surfaces with compositional heterogeneity.

Assessment of Flyby Methods as Applied to Close Encounters among Asteroids
Orbital flybys have been extensively studied for spacecraft missions, resulting in effective mathematical and physical models. However, these models’ applicability to natural encounters involving asteroids has not been explored.

Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia
Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

Photoluminescence and Cathodoluminescence of the Solid Cometary Substance
We have proposed that solar ultraviolet and corpuscular radiations may excite photoluminescence and cathodoluminescence of the solid cometary substance including mineral halos of comets.

Finding the aten asteroids posing potential danger for Earth
We made the research of orbit evolutions of 321 aten asteroids on the 400 years time interval (1800–2200). We found five asteroids which come close to the Earth at a distance less than 150000 km.
