Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, Volume 600, Issue 5, Page 591-611, March 2026.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

A Comet Active Beyond the Crystallization Zone

, 2017
We present observations showing in-bound long-period comet C/2017 K2 (PANSTARRS) to be active at record heliocentric distance. Nucleus temperatures are too low (60 K to 70 K) either for water ice to sublimate or for amorphous ice to crystallize ...

Prediction of the In-Situ Dust Measurements of the Stardust Mission to Comet 81P/Wild 2 [PDF]

, 1999
We predict the amount of cometary, interplanetary, and interstellar cosmic dust that is to be measured by the Cometary and Interstellar Dust Analyzer (CIDA) and the aerogel collector on-board the Stardust spacecraft during its fly-by of comet P/Wild 2 ...

Rotating dust particles in the coma of comet 67P/Churyumov-Gerasimenko [PDF]

Astronomy & Astrophysics, 2015
During September and October 2014, the OSIRIS cameras onboard the ESA Rosetta mission detected millions of single particles. Many of these dust particlesappear as long tracks (due to both the dust proper motion and the spacecraft motion during the exposure time) with a clear brightness periodicity.

Endogenous Repair in Vanishing White Matter

Annals of Neurology, Volume 99, Issue 3, Page 737-747, March 2026.
[Color figure can be viewed at www.annalsofneurology.org] Objective Vanishing white matter is a leukodystrophy with remarkable regional variation in disease severity. The cerebral and cerebellar white matter chronically degenerates, while stress‐induced episodes of rapid neurological deterioration coincide with the appearance of acute focal lesions in ...

WISE/NEOWISE Observations of Comet 103P/Hartley 2 [PDF]

, 2011
We report results based on mid-infrared photometry of comet 103P/Hartley 2 taken during 2010 May 4-13 (when the comet was at a heliocentric distance of 2.3 AU, and an observer distance of 2.0 AU) by the Wide-field Infrared Survey Explorer.

Modeling the effects of a faint dust coma on asteroid spectra [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractIn this work we use a simple model to study the influence of a faint dust coma on asteroid spectra, in an effort to reproduce the unusual spectral behavior seen on the asteroid (5201) Ferraz-Mello and other objects.
