Astronomers conducted molecular gas observations of two enigmatic interstellar objects, which harbor abundant ices of water and organic molecules. The observations with the ALMA telescope have revealed the physical and chemical properties of these objects, but their characteristics do not match those of any previously known interstellar objects where ices have been detected. They may represent a new class of interstellar icy objects that provide an environment conducive to the formation of ices and organic molecules.

Trees compete for space as they grow. A tree with branches close to a wall will develop differently from one growing on open ground.

Now everyone from urban planners and environmental scientists to homeowners may access a new algorithm for tree reconstruction developed at Purdue University to see how the trees will shade an area or learn what a tree will look like in 20 years. Purdue computer scientists and digital foresters used artificial intelligence to generate this first-ever database, which contains three-dimensional models of more than 600,000 real trees.

 A new collaboration among Arizona State University (ASU) , Michigan State University (MSU) and Lawrence Livermore National Laboratory (LLNL) will seek to answer how planets form with the help of a powerful telescope and high-performance computers.
