The human body is an intricate ensemble of prokaryotic and eukaryotic cells, and this coexistence relies on the interplay of many biotic and abiotic factors. The inhabiting microbial population has to maintain its physiological homeostasis under highly dynamic and often hostile host environments. While bacterial colonization primarily relies on the metabolic suitability for the niche, there are reports of active remodeling of niche microenvironments to create favorable habitats, especially in the context of pathogenic settlement.

Peroxisomal biogenesis disorders (PBD) are autosomal recessive disorders caused by loss-of-function mutations of one of the genes responsible for peroxisomal formation. Impaired peroxisome assembly causes severe multisystemic failure with patient phenotypes ranging from epilepsy, liver disease, feeding issues, biochemical abnormalities, and neurodegeneration. Variants in the same gene can produce wide differences in severity, ranging from individuals with death in the first year of life to adults with milder complications.

Background: Autonomic function assessment provides valuable information regarding the status of the autonomic nervous system. The time lag between the onset of orthostasis and the peak/nadir of heart rate response is a surrogate of the integrity of underlying autonomic neural pathways. Autonomic response latency (ARL) is a relatively novel yet underreported parameter in this context.

Article Synopsis
  • X-linked adrenoleukodystrophy (X-ALD) is a genetic neurodegenerative disorder marked by a mutation in a gene that causes the buildup of very long-chain fatty acids (VLCFAs) and leads to a range of symptoms, from early childhood neuroinflammatory disorders in some males to chronic issues in adult males and female carriers.
  • Nearly all male patients show signs of adrenal gland failure, with the age of onset varying and sometimes being the first sign of the disease.
  • Studies in fruit flies reveal that knocking down the fly version of the affected gene leads to VLCFA accumulation and other defects, while overexpressing the human version of the gene may inhibit the creation of peroxisomes, suggesting a

Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems is uncertain, but most theories involve accretion disks around supermassive black holes (SMBHs) undergoing instabilities or interacting with a stellar object in a close orbit. It has been suggested that this disk could be created when the SMBH disrupts a passing star, implying that many QPEs should be preceded by observable tidal disruption events (TDEs).

Adam's Bridge is a submerged ridge connecting India and Sri Lanka, generally regarded as a chain of shoals extending for ~ 29 km from Dhanushkodi on the Indian side to Talaimannar Island of Sri Lanka. A high-resolution digital bathymetric elevation model generated using the seafloor returned photons of ICESat-2 was used to understand the intricate details of Adam's Bridge structure. Photons emanating from ICESat-2's green laser have the potential to detect the seafloor up to a depth of ~ 40 m; taking a cue from this potentiality, in our research, we have accrued ~ 0.

Collective spin-wave excitations, magnons, are promising quasi-particles for next-generation spintronics devices, including platforms for information transfer. In a quantum Hall ferromagnets, detection of these charge-neutral excitations relies on the conversion of magnons into electrical signals in the form of excess electrons and holes, but if the excess electron and holes are equal, detecting an electrical signal is challenging. In this work, we overcome this shortcoming by measuring the electrical noise generated by magnons.

Dust associated with various stellar sources in galaxies at all cosmic epochs remains a controversial topic, particularly whether supernovae play an important role in dust production. We report evidence of dust formation in the cold, dense shell behind the ejecta-circumstellar medium (CSM) interaction in the Type Ia-CSM supernova (SN) 2018evt three years after the explosion, characterized by a rise in mid-infrared emission accompanied by an accelerated decline in the optical radiation of the SN. Such a dust-formation picture is also corroborated by the concurrent evolution of the profiles of the Hα emission line.

This Letter presents a nonlocal study on the electric-field-tunable edge transport in h-BN-encapsulated dual-gated Bernal-stacked (ABA) trilayer graphene across various displacement fields (D) and temperatures (T). Our measurements revealed that the nonlocal resistance (R_{NL}) surpassed the expected classical Ohmic contribution by a factor of at least 2 orders of magnitude. Through scaling analysis, we found that the nonlocal resistance scales linearly with the local resistance (R_{L}) only when the D exceeds a critical value of ∼0.
