Global warming was set in motion around 1600 AD, it seems. 

Because carbon dioxide emissions persist for a long time, even a sudden halt today means the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to a numerical model which suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.

Awe-inspiring moments, like the sight of the Grand Canyon or the Aurora Borealis, might increase our tendency to believe in God and the supernatural, according to a new paper in Psychological Science which suggests that awe-inspiring sights increase our motivation to make sense of the world around us. Learning geology may be too hard to it's easier to default to aliens or religion. 

Zombies are really popular - "...and zombies" attached to the end of well-established works of fiction have become a common trope and once they began to swarm over the literary canon, it was only a matter of time before English Lit academics began to overthink the phenomenon.

An international collaboration has discovered a novel receptor, which allows the immune system of modern humans to recognize dangerous invaders, and subsequently elicits an immune response. The blueprint for this advantageous structure was also identified in the genome of Neanderthals, hinting at its origin.

The receptor provided these early humans with immunity against local diseases. The presence of this receptor in Europeans but its absence in early men suggests that it was inherited from Neanderthals.

The government enjoyed tremendous success steering the goals of science in World War II and that continued during the NASA era. Since that time, government has exercised greater control of science through larger and larger pools of funding that have gradually supplanted corporate basic research.

But government control of funding has its downside; fashions in research funding (solar power now, before that), reward structures in universities that focus on government grants and streamlining of scientific agendas undermine traditional scientific norms and may even result in science bubbles.

This week, Americans officially start focusing on Christmas holiday celebrations and that means a lot of high-calorie food.
