Astrophysicist Avi Loeb contrasts the ancient awe that Moses felt when witnessing the burning bush with modern humanity's overconfidence since Nietzsche's declaration that "God is dead." He argues that the rise of science and technology...

In the past decade, astronomers have discovered interstellar objects, including a 2014 meteor that collided with Earth and 'Oumuamua in 2017. These objects, moving too fast to be bound by the Sun's gravity, have sparked questions about...

Astrophysicist Avi Loeb believes we are likely not alone in the universe. He criticizes the approach of simply waiting for contact through radio signals, suggesting instead that we should actively search for evidence of other life. He...

Global food production - from meat to grains - accounts for a third of all greenhouse gas emissions, says sustainability scientist Jonathan Foley. He presents a portfolio of data-backed solutions to build a better food system world-wide,...

Meet MethaneSAT: the satellite circling Earth right now to track global emissions from methane: a highly potent, short-term greenhouse gas. Environmental advocate Millie Chu Baird details the heat-trapping side effects of a planet full...

Quantum computers obtain superpowers by tapping into parallel universes, says Hartmut Neven, the founder and lead of Google Quantum AI. He explains how this emerging tech can far surpass traditional computers by relying on quantum...

Could math help make American democracy more responsive to the people? From detecting gerrymandered districts to predicting the impact of alternative election methods like ranked-choice voting, neuroscientist Sam Wang outlines how...

Drawing on her research into the science of play, evolutionary biologist Carole K. Hooven delves into how testosterone impacts the body and brain, interacting with culture to create differences in human behavior — starting with why boys...

Malaria is a disease as old as humankind, yet we may be closer than ever to eliminating it, says medical entomologist Abdoulaye Diabaté. He explains the potential of "gene drive" technology — which aims to disrupt mosquito reproduction...

In 2022, physicist Tammy Ma and the team at Lawrence Livermore National Laboratory achieved a scientific breakthrough decades in the making: fusion ignition, or the combining of two atoms to generate more energy out of a reaction than...
