A new study shows that almost none of the behaviors we associate with dog breeds—from lovable Labradors to pugnacious pit bulls—are hard-wired. Aside from a few ancient traits, environment seems to play a much larger role than pedigree.

Professor Ashani Weeraratna has been studying the cancer microenvironment in her lab for the past 17 years. Taking into account that the tissues in our bodies change as we age is important when researching cancer biology. She hopes that gaining a better understanding of how the growth of cancer cells is affected by their direct […]

Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be arranged. Simple rules of probability dictate that it’s much more likely […]

The thought of finding alien life has fascinated people since the time of the ancient Greeks—but developments in astrobiology could be about to turn this possibility into reality. How do you hunt for life beyond Earth—and might this be the decade when we find it?

Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass! The Higgs field and the Higgs mechanism were proposed long ago in order to give particles mass, but it was only in 2012 […]

Fermilab physicists really care about the mass of the W boson. They spent nearly a decade recording collisions in the Tevatron collider and another decade analysing the data. This culminated in the April 7 announcement that this obscure particle’s mass seems to be heavier than expected. So why do we care? Because understanding why this […]

Miguel usa todo su conocimiento e ingenio para contarnos a través de la teoría y haciendo foco en la realidad cómo viajar más rápido que la velocidad de la luz.

The future of humanity seems insecure. Rapid climate change, political division, our greed and failings make it hard to look at our species with a lot of optimism and so many people think our end is in sight. But humans always thought they lived in the end times. Every generation assumes they’re important enough to […]

When it comes to the question of whether AI is an existential threat to the human species, you have Elon Musk in one corner, Steven Pinker in another, and a host of incredible minds somewhere in between. In this video, a handful of those great minds—Elon Musk, Steven Pinker, Michio Kaku, Max Tegmark, Luis Perez-Breva, […]

Interview with Nick Bostrom at the Future of Humanity Institute Oxford University – http://www.simulation-argument.com/ – The simulation argument is continuing to attract a great deal of attention. I regret that I cannot usually respond to individual queries about the argument. http://www.simulation-argument.com/si… ABSTRACT. This paper argues that at least one of the following propositions is true: […]

This year’s season finale of StarTalk on National Geographic TV was Neil deGrasse Tyson’s interview with Stephen Hawking. In memory of his passing, and in celebration of his life, we offer that episode for you here. Also featuring astrophysicist Janna Levin, comedian Matt Kirshen, physicist Michio Kaku, and Bill Nye the Science Guy.
