A research team has developed a high-precision 3D analysis framework that reveals, for the first time, the quantitative rules underlying dormant pruning in pear trees.

When Sam Darnold threw his second interception Thursday night, there was no reason to believe the Seattle Seahawks could come back. The Los Angeles Rams had clearly been the better team. Darnold was ...

Comet 3I/ATLAS is a rare visitor passing briefly through our solar system. Here’s how to find it in the night sky—and what you’ll need to catch a glimpse. Interstellar comet 3I/ATLAS streaks across ...

3I/Atlas, a rare interstellar object that had some astronomers wondering whether it's a spacecraft, will soon reach its nearest point to the sun and Earth. The interstellar comet will come within ...

A stray comet from another star swings past Earth this week in one last hurrah before racing back toward interstellar space. Discovered over the summer, the comet known as 3I/Atlas will pass within ...

Newly discovered comet C/2025 V1 (Borisov), which has some minor similarities to 3I/ATLAS, will make its closest approach to Earth on Tuesday (Nov. 11). However, despite recent rumors, the two objects ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

Having made its closest approach to the sun on Wednesday October 29, comet 3I/ATLAS will soon be visible from Earth again—before it leaves our solar system. While the comet—first spotted in July—has ...
