Early evolutionary history of the seed

Biological Reviews, EarlyView.
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 ...

New Paradigms For Asteroid Formation

, 2015
Asteroids and meteorites provide key evidence on the formation of planetesimals in the Solar System. Asteroids are traditionally thought to form in a bottom-up process by coagulation within a population of initially km-scale planetesimals.

Plaque Morphology‐Dependent Regression of Tandem Coronary Plaques Under Intensive Lipid‐Lowering Therapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report a 54‐year‐old woman with stable angina who exhibited heterogeneous responses of tandem left anterior descending artery (LAD) plaques to intensive lipid‐lowering therapy. Coronary CT angiography performed at another hospital suggested diffuse disease, and she presented to our clinic for a second opinion.

The Distribution of Highly Red-sloped Asteroids in the Middle and Outer Main Belt

The Planetary Science Journal
Red ( S > 10%/0.1 μ m) spectral slopes are common among Centaurs and trans-Neptunian objects (TNOs) in the outer solar system. Interior to and co-orbital with Jupiter, the red ( S ∼ 10%/0.1 μ m) slopes of D-type main-belt and Jupiter Trojan asteroids are

SDSS photometry of Asteroids in Cometary Orbits

, 2012
Aiming at exploring the relationship between asteroids in cometary orbits and other minor body populations from the observational point of view, I explore the large photometric database of the Sloan Digital Sky Survey - Moving Objects Catalog.

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

Deep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.

Scattering V-type asteroids during the giant planets instability: A step for Jupiter, a leap for basalt

, 2017
V-type asteroids are a taxonomic class whose surface is associated to a basaltic composition. The only known source of V-type asteroids in the Main Asteroid Belt is (4) Vesta, that is located in the inner part of the belt.

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Dynamic 3D Simulation of Surface Charging on Rotating Asteroids

The Astrophysical Journal
The surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood.
