Exoplanet detection limits from the neural network framework in the case of HARPS-N solar spectra. Left: Detection limit map in the period-amplitude domain. The red dots indicate the successful detection by the trained NN with a false alarm probability (FAP) > 0.1%. Middle: Amplitude comparison between the injected and recovered signals in the period-amplitude domain. The amplitude difference for most of the recovered signals are < 20%. The large difference at low amplitude (0.1 m/s) is likely due to noise in the data. Right: Phase comparison between the injected and recovered signals in the period-amplitude domain. The phase difference for most of the recovered planets is < 0.04. The large differences at long periods is likely due to a poorer sampling of the phase for long-period planetary signals.--astro-ph.EP

Machine Learning As A Transformative Tool for (Exo-)Planetary Science

by Keith CowingApril 13, 2026April 13, 2026

The exploration of planetary bodies in our Solar system and beyond relies on the processing and interpretation of large, spatio-temporally inconsistent, and heterogeneous datasets.

Energetics associated with the occupancy of the K1 site and the position of the M2 ion. (A) Free energy surface of the concerted motions of Prp11 Lys10 and M2, with the initial PDB conformation marked by a yellow star. (B–D) Representative structures of three metastable states from metadynamics simulations. State 1 (B) represents a PDB-like arrangement where Lys10 (slate blue sticks) remains at the K1 site, and M2 (yellow sphere) is properly positioned at the U6 snRNA triple-helix (yellow cartoon). State 2 (C): Lys10 leaves the K1 site, allowing a K+ ion to occupy it and stabilize M2 in place. State 3 (D): M2 directly coordinates G52, losing its catalytic position and partially occupying the K1 site. -- PNAS

This is an artist's impression of a unique type of exoplanet discovered with the Hubble Space Telescope. The planet is so close it to its star that it completes an orbit in 10.5 hours. The planet is only 750,000 miles from the star, or 1/130th the distance between Earth and the Sun. Credit: NASA, ESA, and A.

Simulating A Living Cell: First Simulation Of An Entire Cell Cycle

Template-based cleavage and condensation. (Top) cleavage. The catalyst contains an active site (shown as colored monomers, and highlighted by the ochre box) and a designated cleavage position (the vertical red line). A molecule is treated as a reactant when a segment within it is complementary to the catalyst’s active site; once this match is found, the molecule is split (the break is highlighted in the figure by a small “explosion”) at the cut position. (Bottom) condensation. The catalyst again features an active site and a suture position. A molecule qualifies as the first reactant if its ending segment complements the first portion of the active site, and another molecule serves as the second reactant if its starting segment complements the second portion of the active site. -- Entropy
