Did you feel it? On Nov. 8, an asteroid brushed right by our little blue sphere in space, giving some of us a genuine scare. I’m not talking some dinky, burns-up-in-our-atmosphere asteroid we scoff at several times a day. We almost got hit by a 400-metre-wide clump of coal and space evil. Although we weren't directly threatened, this time, this incident reminds us just how fragile our planet is, and how Earth has little to no defence plans in the event that an asteroid decides not to take the scenic route.
What will the wars of the future look like? That’s the question posed by a recent issue of the journal Synesis, centred on the theme of “Neurotechnology in National Security.” The issue assembles seven articles discussing the use of emerging brain-related technology for military purposes, detailing practical and ethical issues, and making recommendations for American policy.
A University of Saskatchewan scientist has helped map the genetic blueprint of marijuana, potentially leading to improved research and expanded use of the Cannabis sativa plant. Scientist's believe their findings, made available to researchers worldwide on Oct. 20, can act as a foundation in developing new strains of medical marijuana, as well as strengthen certain traits in hemp.
Groundbreaking new research from the University of Alberta has led to the discovery of a new part of the cells that make up complex life. Four years ago, work began on a project centered on “harmless soil amoeba,” when scientists came across a protein that he had seen before in human cells. The protein is an adaptin that brings things into the cell or expels things. It is the fifth of its kind.
A new Danish study, published in the British Journal of Medicine, shows conclusively that there is no link between cellphone usage and brain cancer. And it won’t change anything. The problem is that once you take on a belief like cellphones causing cancer, scientific evidence won’t easily sway you. The same goes for people who think vaccines cause autism or that climate change is a huge scam perpetrated by greedy governments and windmill makers.
A new software program that minimizes the environmental impact of mining uranium is underway, with almost $1.5 million being invested by the federal and provincial governments. The goal of this software is to reduce the impact to surface and ground water caused by mining — that is, to decrease the amounts of selenium, cobalt, nickel and other elements released into the environment.
Just as the prominence of the World Wide Web has changed drastically, so too has its "raison d’être" — it has gone from a database to a hub of real-time communication and social networks. It spreads ideas, news coverage and multimedia across geographical boundaries instantly, and researchers are constantly trying to make it even more streamlined and efficient.
Gears of War 3 is the best of the series and one of the best games on the Xbox 360. Epic Games have crafted the pinnacle of intense gameplay with tight controls and large set pieces,while giving everything in the gameworld considerable weight. The graphical engine Epic implemented does some amazing things before your eyes.

Some time around midnight eastern time on Sept. 23, a decommissioned NASA satellite fell out of the sky — but nobody knows where. The Upper Atmosphere Research Satellite, or UARS, was launched in 1991. According to NASA, it was “the first multi-instrumented satellite to observe numerous chemical components of the atmosphere for better understanding of photochemistry.”
