Proprioception drives tension wood formation for autotropic straightening and postural control in trees

open access: yesNew Phytologist, EarlyView.
Proprioception controls trunk straightness in trees through opposite tension wood formation. A spherical growth chamber (a), combined with a two‐dimensional rotating clinostat (b2), suppresses gravi‐ and phototropic sensing. The tree is first tilted horizontally (b1), triggering upward gravitropic bending, actuated by tension wood formation on the ...

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

open access: yesSedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

Feedback from the First Supernovae in Protogalaxies: The Fate of the Generated Metals

open access: yesThe Astrophysical Journal, 2003
We investigate the chemo-dynamical effects of multiple supernova explosions in the central region of primordial galaxies using three-dimensional hydrodynamical simulations of the inhomogenous interstellar medium down to parsec-scales. We find that the final protogalactic structure and metal distribution depend strongly on the number of SNe ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

General Relativistic Explosion Models of Core-Collapse Supernovae

open access: yes, 2011
We present results from the first generation of multi-dimensional general relativistic neutrino hydrodynamics simulations of core-collapse supernovae. A comparison with models computed using either the purely Newtonian approximation or the "effective gravitational potential" approach reveals appreciable quantitative differences in the heating ...

Triangulation pointing to core-collapse supernovae with next-generation neutrino detectors [PDF]

open access: yesPhysical Review D, 2019
A core-collapse supernova releases the vast majority of the gravitational binding energy of its compact remnant in the form of neutrinos over an interval of a few tens of seconds. In the event of a core-collapse supernova within our galaxy, multiple current and future neutrino detectors would see a large burst in activity.

On the Destruction and Humanitarianisation of the Health System in Gaza and the Need for a Biopolitical Bioethics

open access: yesBioethics, Volume 40, Issue 8, Page 793-807, October 2026.
ABSTRACT This paper examines Israel's destruction and ‘humanitarianisation’ of Palestinian health systems, arguing that this should be understood as an instance of ‘necropolitics,’ as conceived by Achille Mbembe. We review the extensive, long‐term destruction of health systems in Palestine before 7 October 2023 and the catastrophic acceleration of that

Generalized Chaplygin Gas Models Tested with Type Ia Supernovae

open access: yesThe Astrophysical Journal, 2005
The generalized Chaplygin gas (GCG), with the equation of state p = -A/ρα, was recently proposed as a candidate for dark energy in the universe. In this paper we confront the GCG with Type Ia supernova (SN Ia) data using available samples. Specifically, we have tested the GCG cosmology in three different classes of models with (1) Ωm = 0.3 and ΩCh = 0 ...

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.
