Chandrayaan-3's measurements of sulfur in soils are the first to occur on the Moon. The exact amount of sulfur cannot be determined until the data calibration is completed. The uncalibrated data collected by the LIBS instrument on Pragyan suggests that ... The Hubble Space Telescope has observed the smallest planet outside our solar system to contain water vapor in its atmosphere, a "landmark discovery" that brings astronomy a step closer to characterizing Earth-like worlds. At around twice Earth's diameter, planet GJ 9827d orbits a red dwarf star 97 light-years away in the constellation Pisces ...Furthermore, AI has distinct advantages over humans, such as better speed and memory capacity, fewer physical constraints, and the potential for more rationality and recursive self-improvement.

In 2017, scientists studying bundles of lab-grown cells resembling tiny brains found evidence that disorganized brain cells dividing hurriedly and differentiating too early may give rise to schizophrenia. And in 2021, researchers pinpointed specific genes in the placenta that are active during complicated pregnancies and associated with …What's more, smelling through two nostrils together created two distinct bursts of activity. Though the time delay between them was very short, it was there, and the researchers suggest that this again points to the nostrils not always being in unison. Two nostrils were better than one when it came to identifying odors and identifying them more ...For decades, scientists have debated just how apocalyptic it was when Toba, a supervolcano located in Sumatra, Indonesia, erupted some 74,000 years ago. Some …At a distance of 4.25 light-years (40 trillion km; 25 trillion mi) from the Solar System, even Proxima Centauri is unfathomably far away. To put it in perspective, the record for the farthest distance ever traveled by a spacecraft goes to the Voyager 1 space probe, which is currently more than 24 billion km (15 billion miles) from Earth.
