In 1927, Albert Einstein and Neils Bohr debated the nature of what’s known as complementarity—the idea that a photon’s dual wave-like and particle natures can’t be measured at the same time. Now, two ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

A new database tells the stories of victims of forced medical research during the Nazi era. What role do the specimens and findings from that time play in modern medicine and research? Forced medical ...

These simple, DIY science experiments for kids will help combat "summer slide" — and your kids will be having so much fun, they won't even notice that their brains are getting a workout. The best part ...

In 1971, Stanford University psychologist Philip Zimbardo conducted a notorious experiment in which he randomly divided college students into two groups, guards and prisoners, and set them loose in a ...

Cats may seem solid, but they’re actually somewhat liquid — at least according to one 2017 theoretical physics paper inspired by videos of cats squeezing under doors, into tight vases and down narrow ...

Last year, in July, Reine Protacio’s experiments suddenly stopped working. Every scientist encounters baffling results from time to time; you chalk it up to error, repeat the experiment, and hope for ...

The brain is a mere piece of furniture in the vastness of the cosmos, subject to the same physical laws as asteroids, electrons or photons. On the surface, its three pounds of neural tissue seem to ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

Metaphysics is the branch of philosophy that deals in the deep scaffolding of the world: the nature of space, time, causation and existence, the foundations of reality itself. It’s generally ...

Could we be trapped inside a simulated reality, rather than the physical universe we usually assume? It’s a tantalizing theory, long theorized by philosophers and popularized by the 1999 blockbuster ...

The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, ...
