Fossils uncovered in Spain could lead to new clues about how dinosaurs evolved, according to a study published on Sunday in the science journal Papers in Paleontology. Fidel Torcida Fernandez-Baldor from the Dinosaur Museum of Salas de los Infantes in northern Spain discovered the fossils, which together represent at least five individual dinosaurs. The musuem
OpenScholar is an LLM that performs scientific literature reviews using a database of 45 million open-access articles.Credit: dpa via Alamy Researchers have published the recipe for an artificial-intelligence model that reviews the scientific literature better than some major large language models (LLMs) are able to, and gets the citations correct as often as human experts

In 2023, a subatomic particle smashed into the Mediterranean Sea with enough energy to rattle the foundations of physics. The particle was a neutrino, a fundamental subatomic particle that usually slips through the Earth unnoticed. Approximately 100 trillion neutrinos pass through your body every single second.
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
