Using 3.4 μm Variability toward White Dwarfs as a Signpost of Remnant Planetary Systems

The Astrophysical Journal
Roughly 2% of white dwarfs harbor planetary debris disks detectable via infrared excesses, but only a few percent of these disks show a gaseous component, distinguished by their double-peaked emission at the near-infrared calcium triplet.

Combined Effects of Depression, Fatigue and Cardiovascular Dysfunction on Functional Dependence Over Seven Years in Early Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is associated with both motor and non‐motor symptoms, which collectively impact activities of daily living (ADLs) and contribute to the loss of functional independence. There is a lack of understanding of how non‐motor symptoms drive this loss in independence.

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

General Relativity Can Prevent a Runaway Greenhouse on Potentially Habitable Planets Orbiting White Dwarfs

The Astrophysical Journal
Planets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...

“It's just us”: Families' experiences with temporary tube feeding

Nutrition in Clinical Practice, EarlyView.
Abstract Background Children with temporary feeding tubes are discharged home with increasing frequency, yet little is known about how families adapt and manage in their home environment. Whereas the physical side effects of temporary feeding tubes are well documented, the psychosocial impact on families remains underresearched. Understanding families'

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

The Impact of Breathing Pulses during Core Helium Burning on the Core Chemical Structure and Pulsations of Hydrogen-rich Atmosphere White Dwarfs

The Astrophysical Journal
Breathing pulses are mixing episodes that could develop during the core helium-burning phase of low- and intermediate-mass stars. The occurrence of breathing pulses is expected to bear consequences on the formation and evolution of white dwarfs ...
