A new simulation created using a NASA supercomputer has shown how things get messy for merging neutron stars even before they slam together; their magnetospheres, the most powerful magnetic fields in the known universe, entwine and generate chaos. Neutron stars are the most extreme stellar objects in the universe, created when massive stars die in
TSS selection The selection of relevant TSSs was done as previously described60. In brief, we selected GENCODE-defined TSSs62, with the additional requirement that they are active in at least one cell type or tissue according to the FANTOM5 database63. This process resulted in a curated set of 30,607 TSSs. Genome-wide MPRA dataset The initial PARM
For more than a century, the Green River’s course through the Uinta Mountains in Utah’s northeast has been a geological mystery, seemingly defying physics. Rivers carve their paths by flowing downhill across many years, which means they usually follow the slopes and furrows of any mountain ranges they encounter. And yet the Green River, which
OpenScholar OpenScholar (detailed in Extended Data Fig. 1) is a new retrieval-augmented LM designed to ensure reliable, high-quality responses to a range of information-seeking queries about scientific literature. Task formulation and challenges Given a scientific query x, the task is to identify relevant papers, synthesize their findings and generate a response y that effectively addresses the

On February evenings, look straight up after dark to find Capella, the bright golden star at the heart of Auriga, the Charioteer. It forms a rough pentagon with
Why is one single whale singing at the wrong frequency? That’s a question experts have been discussing since 1989 when US Navy hydrophones detected a strange whale call. Even in the 1980s, hearing whale song on underwater recordings wasn’t unusual – but there was something odd about this sound. It sounded like a whale but
WASHINGTON — NASA officials defended their preparations for the Artemis 2 mission after a fueling test experienced the same type of hydrogen leaks that bedeviled Artemis 1 more than three years ago. NASA wrapped up the wet dress rehearsal, or WDR, for Artemis 2 in the early morning hours Feb. 3 after a hydrogen leak
Each time we’ve looked at the Universe in a fundamentally new way, we didn’t just see more of what we already knew was out there. In addition, those novel capabilities allowed the Universe to surprise us, breaking records, revolutionizing our view of what was out there, and teaching us information that we never could have
A possible rocky exoplanet referred to as a ‘cold Earth’ that could orbit on the outer edge of the habitable zone has been found around a star 146 light-years away. Known as HD 137010b, the exoplanet is considered at this stage to be a candidate world, meaning that its existence has yet to be confirmed.
Space exploration continues to quite literally hit new highs, and this footage shows a spacecraft zooming back down to Earth. After completing a mission, the craft returned to Earth and the views are unlike anything you’ve ever seen before. As well as hitting speeds of Mach 25, the journey ticked off a bunch of firsts
