This illustration shows a red dwarf star orbited by a hypothetical exoplanet. Red dwarfs tend to be magnetically active, displaying gigantic arcing prominences and a wealth of dark sunspots. Red

Graphical Abstract — Genes (Basel) Sequences of tRNAs are highly patterned in easily identifiable RNA repeats and RNA inverted repeats (stem-loop-stems). Because of patterning, the multi-step evolution of tRNA can

A team of researchers at The University of New Mexico has uncovered how a peculiar, prehistoric plant might unlock new ways to reconstruct Earth’s ancient climate. Led by UNM Earth

Cross-correlation function significance plotted as a function of planet velocity amplitude and systemic radial velocity. The significance is the number of standard deviations above the mean for those parameters, peaking

The lifespan of the biosphere is necessarily constrained between the onset of Earth’s habitability (the “habitability window,” constrained between ~4.5 and ~3.9 Ga) (147) and its end (the extinction of

Graphical abstract — Computational simulation/modeling A study led by researchers from the University of Sydney and the University of Adelaide has revealed how the breakup of an ancient supercontinent 1.5

The Teledyne Marine-Rutgers University Sentinel Redwing autonomous underwater vehicle is embarking on an underwater journey that could be a world first: circumnavigating the globe. — Teledyne Marine Editor’s note: When

An artist’s concept of the exoplanet WASP-18b. Credits: NASA/GSFC Astronomers have generated the first three-dimensional map of a planet orbiting another star, revealing an atmosphere with distinct temperature zones—one so
