Over the past decade, the rapid expansion of large-scale data and advances in computational power have allowed machine learning (ML), especially deep learning, to reshape many areas of biological research. […]
SPHEREx is a NASA mission designed to perform an all-sky spectroscopic survey in the 0.75 – 5 μm wavelength range. Its primary science objectives are to investigate: (1) inflationary cosmology, […]
Understanding whether prebiotic molecules can endure and reform through the energetic stages of star formation is essential for tracing the continuity of interstellar chemistry toward life. Glycolamide, an isomer of […]
Recent findings demonstrate that concentrated sulfuric acid supports rich organic chemistry, including the stability of the canonical DNA bases adenine, thymine, guanine and cytosine.
Editor’s note: with recent speculation about the potential habitability of other worlds and understanding the processes whereby other biospheres arise and evolve, thought needs to be given to developing sensor […]
![- [TOP] [X/Fe] vs. [Fe/H] for n-capture elements in the SMC. Abundance patterns are shown for Eu (leftmost panel), Zr (second leftmost) and Ba (second rightmost) and La (rightmost). Solid lines are genuine chemical evolution tracks for the reference models adopting Rubele et al. (2018) SFH (blue) and Massana et al. (2022) SFH (green), whereas shaded cyan and light-green regions are associated model predictions account for observational uncertainties (’synthetic models’). Data are from Anoardo et al. (2025, Eu) and Mucciarelli et al. (2023a, Zr, Ba, La) for SMC field stars (orange dots) and Mucciarelli et al. (2023b) for SMC GCs (black dots). Orange contour lines represent density lines of the observed stellar distributions in SMC field stars. - [BOTTOM] [X/Fe] vs. [Fe/H] for n-capture elements for the model adopting Rubele et al. (2018) SFH with increased MNS r-process production at low-metallicity (see Eq. (4)). Blue solid lines and cyan shaded regions represent genuine chemical tracks and model predictions accounting for observational uncertainties (’synthetic model’), respectively.

Context. In the context of galactic archaeology, the study of the Small Magellanic Cloud (SMC) is of crucial importance, as it represents a unique opportunity to study a nearby massive […]
Two microscopic grains collide and produce a tiny spark. This phenomenon may have provided the energy to kick off life on Earth. But if these solid particles have the same […]

A new collaboration between EMBL’s European Bioinformatics Institute (EMBL-EBI), Google DeepMind, NVIDIA, and Seoul National University has made millions of AI-predicted protein complex structures openly available through the AlphaFold Database. […]
I present a spatially resolved analysis of the polycyclic aromatic hydrocarbon (PAH) population in the Pillars of Creation within the Eagle Nebula (M16) using the James Webb Space Telescope’s (JWST) […]
