Where will the best real estate outside of Earth be? In this fascinating talk, The building of the most accurate space colony simulator examines the evidence that “we can do better than Mars.”

Joe Strout’s programming career began at a young age, writing articles for “Nibble” magazine in high school. Joe obtained a bachelors in psychology from the University of Miami and a masters in neuroscience from the University of California, San Diego, but couldn’t resist the call of code and became a full-time software developer after graduate school. He now runs a consulting business, crafting unique software solutions to a wide range of problems. Joe and his two sons have been working on High Frontier for almost a year, and ran a successful Kickstarter campaign in November 2015.

Computronium is defined by some as a substance which approaches the theoretical limit of computational power that we can achieve through engineering of the matter around us. It would mean that every atom of a piece of matter would be put to useful work doing computation. Such a system would reside at the ultimate limits of efficiency, and the smallest amount of energy possible would be wasted through the generation of heat. Computronium crops up in science fiction a lot, usually as something that advanced civilizations have created, occasionally causing conflicts due to intensive harvesting of matter from their galaxy to further their processing power. The idea is also also linked with advanced machine intelligence: A block of matter which does nothing other than compute could presumably would be incredibly sought after by any artificial intelligence looking to get the most compact and powerful brain for its money!

It sounds like a plot from a comic book or a sci-fi film, a theory that got a boost when one of the greatest discoveries in physics in the modern era, the discovery of the “God particle,” or the Higgs boson, the missing piece in the Standard Model of particle physics. In the preface to his book Starmus, Stephen Hawking warns that the Higgs Boson field could collapse, resulting in a chain reaction that would take in the whole universe with it.

Theoretical physicist Joseph Lykken says it would probably take billions of years before we reach that point. Lykken hails from the Fermi National Accelerator Laboratory in Batavia, Illinois. If it did happen though, you wouldn’t know it. One instant you are here, the next, you and everything else is swallowed up by an enormous vacuum bubble, traveling at light speed in every direction. Humanity would never see it coming.

As atoms in our bodies were made in stars millions of years ago, it’s been common to propose that we are, in fact, made of stars. Now comes news of another mind-blowing cosmic relationship as physicists conclude that human cells and neutron stars share structural similarities, which look like multi-story parking garages.

Neutron stars are quite strange space objects. They come to life as a result of supernova explosions of massive stars and are incredibly dense. While they are the smallest stars, they can pack as much mass as two Suns into a star with the radius of just 10 kilometers.

Biologists at Caltech have developed a new system for visualizing connections between individual cells in fly brains. The finding may ultimately lead to “wiring diagrams” of fly and other animal brains, which would help researchers understand how neurons are connected.

“To understand how the brain works we need to know how neurons are wired to each other,” says Carlos Lois, research professor in the Division of Biology and Biological Engineering at Caltech and principal investigator of the new research, which appears in the November issue of the journal Development. “This is similar to understanding how a computer works by looking at how transistors are connected.”

Animals are made up of different types of specialized cells. In order for an animal to function, the cells have to be able to communicate with each other. For example, neurons directly communicate with muscle cells so that an animal can move. In diseases such as cancer, this communication process can go awry: when tumors metastasize, they no longer “listen” to neighboring cells that tell them not to grow. Instead, the cancer cells grow uncontrollably and migrate to other parts of the body.

For wireless communication, we’re all stuck on the same traffic-clogged highway—it’s a section of the electromagnetic spectrum known as radio waves.

Advancements have made the highway more efficient, but bandwidth issues persist as wireless devices proliferate and the demand for data grows. The solution may be a nearby, mostly untapped area of the electromagnetic spectrum known as the terahertz band.

“For wireless communication, the terahertz band is like an express lane. But there’s a problem: there are no entrance ramps,” says Josep Jornet, PhD, assistant professor in the Department of Electrical Engineering at the University at Buffalo School of Engineering and Applied Sciences.

A new theory explains how fragile quantum states may be able to exist for hours or even days in our warm, wet brain. Experiments should soon test the idea.

AN ICONIC physics experiment may be hiding more than we ever realised about the nature of reality. The classic “double-slit” experiment reveals the strange duality of the quantum world, but it may behave more strangely than we thought – and could challenge one of the most closely held assumptions of quantum mechanics.

Revisiting it could help unify quantum mechanics with the other pillar of theoretical physics – Einstein’s general relativity – a challenge that has so far proven intractable.
