For the urban (combat) gentleman. An exclusive line of bullet proof clothing. Unlike traditional body armour, this is actually pretty good looking stuff, and not likely to draw attention to whatever it is you’re doing in an inconspicuous bullet proof shirt. Manufacturer ANXO are your people when you need a new shirt then.
Quite frankly incoprehensable news from the world of science today. Apparantly the planet ane everything on it could be holograms. I’m not sure I really get it.
The holograms you find on credit cards and banknotes are etched on two-dimensional plastic films. When light bounces off them, it recreates the appearance of a 3D image. In the 1990s physicists Leonard Susskind and Nobel prizewinner Gerard ‘t Hooft suggested that the same principle might apply to the universe as a whole. Our everyday experience might itself be a holographic projection of physical processes that take place on a distant, 2D surface.
The 3D information about a precursor star can be completely encoded in the 2D horizon of the subsequent black hole – not unlike the 3D image of an object being encoded in a 2D hologram. Susskind and ‘t Hooft extended the insight to the universe as a whole on the basis that the cosmos has a horizon too – the boundary from beyond which light has not had time to reach us in the 13.7-billion-year lifespan of the universe.
Whuh? Yeah, no, I didn’t get it either. Read more, if you can get your head round it at New Scientist LINK
Although not quite as complex as ol’ Frankie up there,Scientists have created something that could be called life. Wait, what?
A test tube based system of chemicals that exhibit life-like qualities such as indefinite self-replication, mutation, and survival of the fittest, has been created by US scientists. The researchers say their perpetually replicating RNA enzymes take us a step closer to understanding the origins of life on Earth, as well as to how life may one day be synthesised in the lab.
This parallels what happens in biological systems, like natural selection or survival of the fittest,’ says Joyce. (The scientist behind the experiment) ‘It isn’t alive, however, because what it doesn’t have is the ability to invent novel functions out of whole cloth. If it could do that then most scientists would say that it crossed the line into life.’
