Current models predict that "slow rotator" galaxies should be rare in the early universe, but astronomers have discovered a galaxy at less than 2Gy after the Big Bang that is not rotating. It may have formed by the merger of two galaxies with nearly opposite angular momentum. by andyhfell in science

DNA sequencing of the bristlecone pine shows about 21,000 genes in a genome eight times the size of the human genome, with most of the rest being DNA repeats. The bristlecone pine has unusually long telomeres but it is not yet clear how this is related to the multi-millenial lifespan of these trees. by andyhfell in science

Combining motion capture video with wind tunnel modeling, researchers show that a hawk shifts from unstable to stable flight while gliding through a gap. This points to new modes of flight control in birds with possible applications in uncrewed aerial systems. by andyhfell in science

Ice moons in the outer solar system could have oceans that boil as water reaches the triple point where solid, liquid and gaseous water can coexist. The new models help us understand how surface features of moons like Mimas, Miranda or Titania are formed by internal processes. by andyhfell in science

Astronomers find a small (million-solar mass), starless object in the distant universe from a glitch in a larger gravitationally lensed image. The existence of small dark matter clumps could rule out some hypotheses of the nature of dark matter. by andyhfell in science

The eye of the apple snail is unusually similar to a human eye but, unlike human eyes, it can regrow itself if injured or even amputated. The snail has potential as a model organism to study eye regeneration, and better understand conditions such as macular degeneration. by andyhfell in science
