Bolide Light Curve Systematics from 75 Recovered Meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Pinus‐derived membrane vesicles disrupt pathogenic metabolism in fungi

Plant Biology, EarlyView.
Needle‐derived vesicles from pine trees impair fungal metabolism and growth, offering a sustainable strategy to control pine pitch canker disease. Abstract Much of what we know about the biological impacts of vesicles (MVs) is derived from Arabidopsis thaliana.

Understanding turbulence suppression in JET D–T plasma with highly energetic fast ions via global gyrokinetic GENE simulations

Nuclear Fusion
This study focuses on understanding how turbulence is suppressed in particularly heated JET plasma discharges showing enhanced confinement, namely $99896$ , which uses a nearly 50–50 deuterium–tritium mixture, showing signs of enhanced plasma confinement.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Beta-dependent Properties of Solar Wind Current Sheets at 1 au

The Astrophysical Journal Letters
We utilize plasma turbulence in interplanetary coronal mass ejections as a natural laboratory to analyze more than 4600 current sheets observed over a broad range of electron and proton beta values, 10 ^−2  ≲  β _e  ≲  10 and 10 ^−3  ≲  β _p  ≲  10.

An acute crossover trial of passive movement training with and without blood flow restriction to determine the impact on postprandial glycaemia

Experimental Physiology, EarlyView.
Abstract During glucose uptake into muscle, GLUT‐4 can translocate with stimulus from insulin or muscle contraction via exercise, but some exercise‐intolerant populations are unable to benefit from improved glycaemic control. We investigated how passive movement training (PMT) and passive movement training with blood flow restriction (PMT+BFR) could be

Maximal exercise at high altitude does not exacerbate inflammation in the human brain

The Journal of Physiology, EarlyView.
Abstract figure legend This study investigated arterial–internal jugular venous (IJV) exchange of cytokines in response to low‐intensity and maximal cycling exercise at sea level and following 6–8 days at 3800 m a.s.l. There was a shift towards net release of interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), monocyte chemoattractant protein‐1 (MCP‐1) and ...

Magnetic geometry effects on turbulent density fluctuations in Wendelstein 7-X

Nuclear Fusion
Line-integrated density fluctuation measurements from the core of the optimised stellarator Wendelstein 7-X (W7-X) are studied in the context of magnetic field geometry changes.
