ENG: Researchers at the University of Texas at Dallas have developed a new method that could make same-day, 3D-printed zirconia dental restorations possible. Zirconia is widely used for permanent crowns, bridges, and veneers because of its strength and durability, but traditional 3D-printing methods require a lengthy debinding process that can take 20 to 100 hours. The UT Dallas team reduced this step to less than 30 minutes by combining improved heat transfer, porous graphite felt, and a vacuum system that safely removes gases released from the printed material.
A Rare Glimpse Into the Birth of a Supernova
ENG: Astronomers captured an exceptionally rare view of a star exploding almost from the moment the event began. On March 21, 2026, the Einstein Probe detected a brief pulse of soft X-rays from a galaxy about 500 million light-years away. The signal, known as EP260321a, was identified as a “shock breakout,” the first flash produced when the shock wave from a collapsing star reaches its surface and releases radiation into space. Less than an hour later, telescopes on Earth observed the supernova, named SN 2026gzf, rapidly becoming brighter.
