One of the big ideas of modern science is that small things can sometimes have huge, irreversible consequences. These so-called tipping points crop up in all walks of life, from economics and finance to human health and the environment. Indeed, they are a fundamental feature of what scientists call complex systems.In an effort to better understand tipping points, scientists have invested much time and effort into simulating complex systems like the climate and the economy, and then gathering dat ...read more
We don’t know how language first began. The first writing didn’t occur until around 3200 B.C.E., and we know that spoken language came before that. Some experts contend that it started with hand gestures along with sounds and signals that, in short order, gave humans a leg up when it came to survival.Fast forward a few thousand years, and the ancients were steeped in it. The Ancient Greeks, for example, were known for their linguistic achievement. By this time, an abundance of languages woul ...read more
Zombies strike fear into our hearts – and if they’re persistent, eventually, they get inside our heads. Animals taken over by zombies no longer control their own bodies or behaviors. Instead, they serve the interests of a master, whether it’s a virus, fungus or some other harmful agent.The term “zombi” comes from Vodou, a religion that evolved in the Caribbean nation of Haiti. But the idea of armies of undead, brain-eating human zombies comes from movies, such as “Night of the Living ...read more
Bottlenose dolphins in Sarasota Bay in Florida and Barataria Bay in Louisiana are exhaling microplastic fibers, according to our new research published in the journal PLOS One.Tiny plastic pieces have spread all over the planet – on land, in the air, and even in clouds. An estimated 170 trillion bits of microplastic are estimated to be in the oceans alone. Across the globe, research has found people and wildlife are exposed to microplastics mainly through eating and drinking but also through b ...read more
Fusion energy has the potential to be an effective clean energy source, as its reactions generate incredibly large amounts of energy. Fusion reactors aim to reproduce on Earth what happens in the core of the Sun, where very light elements merge and release energy in the process. Engineers can harness this energy to heat water and generate electricity through a steam turbine, but the path to fusion isn’t completely straightforward.Controlled nuclear fusion has several advantages over other powe ...read more
