Why AI language models choke on too much text
Compute costs scale with the square of the input size. That's not great. Large language models represent text using tokens, each of which is a few characters. Short words are repr.....»»
Latest gravitational wave observations conflict with expectations from stellar models
Almost 300 binary mergers have been detected so far, indicated by their passing gravitational waves. These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging objects such as black hol.....»»
Chang"e-6 farside basalts reveal a reinforced lunar dynamo
The evolution of the lunar dynamo is crucial for understanding the moon's deep interior structure, thermal history, and surface environment. A study by Chinese scientists conducted paleomagnetic analyses on basalts returned by the Chang'e-6 mission a.....»»
Compact on-chip polarimeter measures light polarization with high accuracy
Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made of bulky components, which makes them difficult to.....»»
Active particles reorganize 3D gels into denser porous structures, study shows
Colloidal gels are complex systems made up of microscopic particles dispersed in a liquid, ultimately producing a semi-solid network. These materials have unique and advantageous properties that can be tuned using external forces, which have been the.....»»
