Our capability to render virtual realities better and better makes it seem likely one day we could simulate our world flawlessly, and perhaps our minds too. If so, perhaps we will in the future… and perhaps we already did in the past.

Physicists are building neural networks out of vibrations, voltages and lasers, arguing that the future of computing lies in exploiting the universe’s complex physical behaviors.

In Episode 3 we look at the concept of warp drives, a theoretical type of spaceship propulsion that warps spacetime to allow faster than light travel. We discuss the basic concept and the scientific and technological hurdles to developing it, along with clearing up many of the myths about it.

Black Holes are amongst the most destructive things in the Universe, but it may be that properly utilized, they might be the best places in the galaxy to live around in the future, and possibly right here in our own solar system too.

The Fermi Paradox contemplates the weirdness of our galaxy seemingly being devoid of intelligent alien life, but Many Worlds Theory, Multiverses, Parallel Universe, and Alternate Realities may radically alter our thinking on Aliens & SETI.

Here’s an intriguing idea. What if you were informed that everything in your life was pre-planned? Even crazier, what if your history, present, and future are all taking place right now?

An incredible new theory established as the “block universe” theory asserts that time does not actually “flow like a river”; rather, everything is ever-present.

Dr. Bradford Skow, a philosophy professor at the Massachusetts Institute of Technology, proposes that if we “look down” on the cosmos as if it were a piece of paper, we would see time stretched out in all directions, just as we perceive space at any given time.

Finding and fixing bugs in code is a time-consuming, and often frustrating, part of everyday work for software developers. Can deep learning address this problem and help developers deliver better software, faster? In a new paper, Self-Supervised Bug Detection and Repair, presented at the 2021 Conference on Neural Information Processing Systems (NeurIPS 2021), we show a promising deep learning model, which we call BugLab can be taught to detect and fix bugs, without using labelled data, through a “hide and seek” game.

To find and fix bugs in code requires not only reasoning over the code’s structure but also understanding ambiguous natural language hints that software developers leave in code comments, variable names, and more. For example, the code snippet below fixes a bug in an open-source project in GitHub.

Near-invisible graphene tattoos deliver high-speed and long-term continuous monitoring of blood pressure with high accuracy.

Wrapping a cuff around a patient’s arm and inflating it to measure blood pressure is one of the most routinely performed medical tests. It provides a quick and reliable assessment of cardiovascular health, as blood pressure is an independent predictor of all-cause mortality. But such arm cuffs are bulky and uncomfortable, making them impractical for continuous monitoring outside of clinics.

For this reason, researchers are developing cuffless alternatives with the goal of unlocking new possibilities for patient diagnostics and management, as well as providing new understanding of physiology. However, none of these tools has become a mainstay yet.
