Researchers from the Universidad de Santiago de Chile and the University of Notre Dame, working with machine learning, have devised a method to identify organic compounds based on the refractive index at a single optical ...
A large international team of space scientists has discovered that the detection of an exoplanet orbiting the star 40 Eridani was made in error. The group has published a paper on the arXiv pre-print server describing their ...
In places across the U.S., tree cover is shrinking—forests are burned by wildfires on the West Coast and drowned by rising sea levels along the East. From the ground, it's hard to assess the scale of the losses and the ...
