US Concerns about Biosecurity Could Hamper Collaborations in Viral Research

U.S. Federal health agencies have started to tighten security surrounding the research on deadly pathogens. The move is to enhance public safety, but some fear that this might hamper research.

Moratorium into Research of Modified Contagious H5N1 Avian Flu Strains

h5n1-big-virus

Researchers have agreed to pause their work into the H5N1 avian influenza virus for the next 60 days. The research involved creating extra-contagious versions of the virus and seeing how it propagates among lab animals to enable the establishment of a propagation model.

Paracompact Spaces

I

It’s strange that I was actually researching paracompact topological spaces on Sunday and that we are seeing those types of spaces in my complex analysis class. We just started the Berenstein & Gay Complex Variables¹ book and things are pretty interesting. I actually deduced that we were heading there because of some of the concepts that we are seeing.

A paracompact space is a topological space in which every open cover admits an open locally finite refinement.

Rainy Mathematical Days

The rain has finally abated. I love the rain in Canada, but I hate it here. Why? You just get wet all the time. You get wet when you get on the scooter, when you drive around, and when you get off. Rain gear does wonders, but it’s annoying to have to carry it around and wait for it to dry. Also, driving in the rain is a lot more dangerous. I tend to be really careful.

Temperatures have cooled down significantly. It’s no longer 30C, but only 24C³. It’s getting a bit chilly when riding on the scooter. I’ll need to take a scarf.

Monoceros Ring

The Monoceros Ring is a proposed ring of stars around the Milky Way which consists of a stellar stream torn from the Canis Major Dwarf Galaxy as it merges with the Milky Way over the course of billions of years. It is a complex ringlike structure which wraps around our galaxy three times, formed from the long filament of stars pulled from the Canis Major Dwarf Galaxy by tidal forces as it orbits the Milky Way. The ring has a mass of 100 million solar masses and is 200,000 light years long.

It’s come up a few times in the last few weeks.

Andromeda Milky Way Collision

The Andromeda-Milky Way collision is a predicted galaxy collision that is due to take place in approximately 3 billion years’ time between the two largest galaxies in the Local Group – the Milky Way and the Andromeda Galaxy.

*

Central to Alastair Reynolds’ science fiction books in the Revelation Space universe, the Andromeda-Milky Way collision is set to occur in about 3 billion years. A machine race named the Inhibitors, that stems from organic quadrupeds, have designated themselves the shepherds of the galaxy and are culling any spacefaring civilisation in order to minimize the effect of the collision. They are moving star systems around, but they are also suffering from enthropy. The Dawn War happened millions of years ago and the Inhibitors have decided on a form of post-intelligence as non-sapients, meaning that they aren’t aware, and wholly machine.

They possess advanced technology with is partly based on femtotechnology or structured space-time and are Von Neumann machines, capable of self-replication. By confining intelligent life to just a few systems, the Inhibitors make moving solar systems around a far easier and more centralized task.

It is likely that the two galaxies will merge and the resulting galaxy will be called Milkomeda. Andromeda is believed to have collided with another galaxy in the past. Such events are quite common on the galactic scale.

Computronium

In futures studies, computronium refers to a hypothetical material engineered to maximize its use as a computing substrate. While futurists usually use it to refer to hypothetical materials engineered on the molecular, atomic, or subatomic level by some advanced form of nanotechnology, the term can also be applied both to contemporary computing materials, and to constructs of theoretical physics that are unlikely to ever be practical to build.

Many futurists speculate about futures where demand for computing power grows to the point where very large amounts of computronium are desired. Examples of applications include Jupiter brains, planet-sized constructs made of computronium, and matrioshka brains, concentric Dyson spheres designed to extract all possible energy from the host star for use towards computation.

*

Computronium is used quite a lot in science-fiction. Just in Alastair Reynolds’ Revelation Space books, there are multiple applications of this. I remember that in the Iain M. Banks book Matter, the book takes place on a shellword, a sort of Dyson sphere with multiple layers.
