A Ground-based Transit Observation of the Long-period Extremely Low-density Planet HIP 41378 f

open access: yesThe Astronomical Journal
We present a ground-based transit detection of HIP 41378 f, a long-period ( P = 542 days), extremely low-density (0.09 ± 0.02 g cm ^−3 ) giant exoplanet in a dynamically complex system.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d

open access: yesThe Astronomical Journal
LP 791-18 d is a temperate Earth-sized planet ( R _P = 1.03 R _⊕ , P = 2.76 days) orbiting a late M dwarf, with an interior super-Earth (LP 791-18 b, R _P = 1.2 R _⊕ , P = 0.95 days) and an exterior sub-Neptune (LP 791-18 c, R _P = 2.5 R _⊕ , P = 4.99 ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

A Planet Candidate Orbiting near the Hot Jupiter TOI-2818 b Inferred through Transit Timing

open access: yesThe Astrophysical Journal
TOI-2818 b is a hot Jupiter orbiting a slightly evolved G-type star on a 4.04 day orbit that shows transit timing variations (TTVs) suggestive of a decreasing orbital period. In the most recent year of TESS observations, transits were observed ∼8 minutes

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Investigation of Transit Timing and an Optical Transmission Spectrum of the Hot Jupiter WASP-11 b

open access: yesThe Astronomical Journal
WASP-11 b/HAT-P-10 b is an inflated hot Jupiter, which has a low density that makes it a good target for atmospheric studies using the transmission spectroscopy technique.

FORECASTING TRANSIT WALK ACCESSIBILITY: REGRESSION MODEL ALTERNATIVE TO BUFFER METHOD

open access: yes, 2003
A description is given of a methodology for estimating transit walk accessibility at the home end of transit trips and for forecasting transit walk accessibility at the home end for a future year, given forecast population and employment data, transit ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
