Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the narratives and artworks of Indigenous cultures, these cosmic spectacles are now known as core-collapse ...
Antarctic sea ice plays a critical role in regulating Earth's climate. It reflects sunlight back into space, insulates the ocean from the atmosphere, and supports unique polar ecosystems.
One September day, it started to snow inside MIT's Pierce Laboratory. Researchers depressurized a tank of liquid carbon dioxide (CO2), instantly freezing it and releasing solid flakes. These were blended into cement paste ...
GaN-based vertical-cavity surface-emitting lasers (VCSELs) are promising for displays, sensing and optical communication, but improving efficiency remains challenging. Researchers have now shown that "cavity tuning," which ...
In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will ...
Over the past several decades, light sources have gradually transitioned to light-emitting diodes, or LEDs, and inorganic LEDs are now used across a wide range of applications. In parallel, organic LEDs, or OLEDs, have become ...
Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside cells that had previously ...
Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and wave-like behaviors, ...
Modern fluorescence microscopy can generate images of living cells as stunning to look at as they are informative to study. For techniques like fluorescence lifetime imaging microscopy (FLIM), those images provide a window ...
Conventional cancer treatments, such as chemotherapy, often lack specificity and can damage both cancerous and healthy cells, leading to severe side effects. With this in mind, researchers at Indian Institute of Technology ...
