When a massive star collapses or two neutron stars collide billions of light-years away, the explosion can unleash a brief, blinding flash of gamma rays. Catching that flash and pinpointing its origin ...

Gamma-ray bursts (GRBs) rank among the most powerful explosions in the Universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first ...

[Left] Semiconductor layers are stacked using concentric metalenses as alignment marks. [Right] Light shines through these marks to project a hologram. The alignment or misalignment of the lenses ...

Movie alignment software uses a 3D spline model to capture beam-induced motion in cryo-electron microscopy movie frames, correct local sample distortions, and improve two-dimensional template matching ...

Digital 3D scanners are revolutionary tools for measuring changes in orthodontics, periodontics, and tooth wear. While most studies focus on the accuracy of the 3D scanning process, obtaining the ...

Three new articles present major advances in understanding the evolution of birds and mammals, made possible by new methods for comparing the genomes of hundreds of species. Researchers developed a ...
