Update and ADMET Profile of the Latin American Natural Product Database: LANaPDB

Molecular Informatics, Volume 44, Issue 11-12, November‐December 2025.
LANaPDB was updated with 1,164 nonduplicate new compounds coming from Argentina and Panama. Moreover, 41 ADMET (absorption, distribution, metabolism, excretion, and toxicity)‐related parameters were determined, and the results were compared with the Universal Natural Products Database and the approved small‐molecule drugs.

Cutoff and Emergence of Dart Leaders in an Unbranched Positive Leader Simulation

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Channel cutoff is the process by which an active lightning channel cools down, goes dark, and loses its ability to effectively conduct electricity. Current cutoff precedes several lightning phenomena, notably dart leaders and return strokes, but the process by which a hot, highly‐conducting leader channel can undergo current cutoff is poorly ...

Measuring the intergalactic medium correlation length at 5 < z < 6.1: A fast change at the end of reionization

Astronomy & Astrophysics
Context. The Lyman-α forest of high-redshift quasars is a powerful probe of the late stages of the epoch of reionization (EoR), in particular thanks to the presence of Gunn-Peterson troughs.

Cosmic Reionization On Computers: Reionization Histories of Present-day Galaxies [PDF]

The Astrophysical Journal, 2019
Abstract We examine the reionization history of present-day galaxies by explicitly tracing the building blocks of halos from the Cosmic Reionization On Computers project. We track dark matter particles that belong to z = 0 halos and extract the neutral fractions at corresponding positions during rapid global reionization.

Therapeutic Implications of Biomolecular Corona on Lipid Nanoparticle‐Based Gene Delivery Systems

Small Science, Volume 5, Issue 9, September 2025.
This image illustrates the role of the biomolecular corona in lipid nanoparticles (LNPs), highlighting its impact on the stability, immune response, biodistribution, and targeted delivery. Formed after injection, the corona influences how LNPs circulate, interact with the cells, and modulate the immune response.

Establishing a relationship between the cosmological 21 cm power spectrum and interferometric closure phases

Astronomy & Astrophysics
Context. Measurements of the cosmic 21 cm background need to achieve a high dynamic range to isolate it from bright foreground emissions. Instrumental calibration inaccuracies can compromise the spectral fidelity of the smooth foreground continuum ...

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Asking Fast Radio Bursts for More than Reionization History

The Astrophysical Journal
We propose different estimators to probe the intergalactic medium (IGM) during the epoch of reionization (EoR) using the dispersion measure (DM) of the fast radio bursts. We consider three different reionization histories, which we can distinguish with a

The 21cm–galaxy cross-correlation: Realistic forecast for 21cm signal detection and reionisation constraints

Astronomy & Astrophysics
Context. The 21cm–galaxy cross-correlations are expected to play a key role in the confirmation of the cosmological 21cm signal. Aims. We investigate which survey configurations detect the 21cm–Lyman-α emitter (LAE) cross-correlation signal and assess ...

Secondary CMB anisotropies in a universe reionized in patches

, 1998
In a universe reionized in patches, the Doppler effect from Thomson scattering off free electrons generates secondary cosmic microwave background (CMB) anisotropies.
