Researchers show that these corals first began declining in the 1950s and 1960s, earlier than previously thought. (1) Even the most primitive actions of people alter the planet. Even the…

But this goes even further than that. Not knowing something is the sole pre-requisite of handling it. Because if you knew it,…

In a UCI study, participants sat with their heads inside a high-resolution fMRI scanner while watching a TV show and then viewing still frames from the episode, one at a time. The researchers found that when subjects had more precise answers to questions about what time certain events occurred, they activated a brain network involving…

Time. Universe. Timeless…
According to a new interpretation of general relativity, the Big Bang wasn’t the start of ‘everything’. Based on a new model, some scientists showed that as we rewind time back to the beginning the universe does not diminish into a singularity, but at something the team call a Janus Point, named after the Roman god…
