Skip to main content Tens of thousands of years ago, small bands of foraging humans left few long-lasting impacts on their environment. Today, we carve huge and indelible marks on the landscape, including megacities, large-scale agriculture, and widespread deforestation. Humans have even changed the chemistry of Earth’s sediments with industrial pollution, radioactive fallout from nuclear tests, and rising levels of nitrogen from fertilizers.

Skip to main content SignificanceDo humans cooperate when facing extremely low survival chances? Are preexisting social ties increasing one’s chances of survival in life-and-death situations? Testimonies of surviving prisoners of deadly internment camps imply a critical role of the ability to form small mutual-support groups, but survivor testimonies are fundamentally selective.

Tom Kinoshita’s calculations made quantum electrodynamics (QED) the most precise theory in the history of human thought. That theory began as a way to conceive the interaction between light and matter, but efforts to make precise predictions quickly ran into serious complications. Enter Kinoshita.

SignificanceDo we only hear sounds? Or can we also hear silence? These questions are the subject of a centuries-old philosophical debate between two camps: the perceptual view (we literally hear silence), and the cognitive view (we only judge or infer silence). Here, we take an empirical approach to resolve this theoretical controversy. We show that silences can “substitute” for sounds in event-based auditory illusions.
