Pedo‐Climatic Controls on Soil Health Recovery Across Cultivation Chronosequences: Hydraulic Conductivity as a Potential Link Between Soil Structure, Microbial Biomass, and Nutrient Availability

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

open access: yesThe Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.

The TESS-Keck Survey. VII. A Superdense Sub-Neptune Orbiting TOI-1824

open access: yesThe Astronomical Journal
We confirm a massive sub-Neptune-sized planet on a P = 22.8 days orbit around the star TOI-1824 ( T _eff = 5200 K, V = 9.7 mag). TESS first identified TOI-1824 b (formerly TOI-1824.01) as an object of interest in 2020 April after two transits in Sector ...

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

open access: yesThe FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Confirming the Warm and Dense Sub-Saturn TIC 139270665 b with the Automated Planet Finder and Unistellar Citizen Science Network

open access: yesThe Astronomical Journal
We report the discovery and confirmation of the Transiting Exoplanet Survey Satellite (TESS) single-transit, warm and dense sub-Saturn, TIC 139270665 b. This planet is unusually dense for its size: with a bulk density of 2.13 g cm ^−3 (0.645 R _J , 0.463

Long‐read sequencing‐based atlas of tissue‐specific expression of DNM1L transcript variants

open access: yesThe FEBS Journal, EarlyView.
Targeted long‐read sequencing resolves full‐length DNM1L (Drp1) isoforms and reveals conserved, tissue‐specific expression patterns across human and mouse tissues. Functional assays show that Drp1 isoforms differ in their ability to drive mitochondrial fission, independent of abundance, with specific exons modulating activity.

TOI-2015 b: A Warm Neptune with Transit Timing Variations Orbiting an Active Mid-type M Dwarf

open access: yesThe Astronomical Journal
We report the discovery of a close-in ( P _orb = 3.349 days) warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ( d = 47.3 pc) active M4 star, TOI-2015.

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

open access: yesThe FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

HST/FGS Photometry of Planetary Transits of HD 209458 [PDF]

open access: yesAIP Conference Proceedings, 2004
We present the data, and modeling and analysis results from the photometric monitoring of five planetary transits of HD 209458 using the Fine Guidance Sensors (FGS) onboard the Hubble Space Telescope (HST). We have now included the output from all four FGS photometers in our data reduction and analysis increasing our S/N over our previous results.
