Events in HBO’s Game of Thrones TV series have got people talking about what it means to return from the dead. But while resurrection appears to be a very real possibility for some of the religions of mythical Westeros – not least Jon Snow’s resurrector, the “red priestess”, Melisandre – what can the Bible add to the discussion?

Smell in mammals turns out to be more complex than we thought. Rather than one receptor family exclusively dedicated to detecting odors, a study in mice reports that a group of neurons surrounding the olfactory bulb use an alternative mechanism for catching scents. These "necklace" neurons, as they're called, use this newly discovered olfactory detection system to respond to odors that elicit instinctive responses, such as pheromones and the smell of seeds and nuts. Harvard researchers report the finding May 26 in Cell.

Earlier this month, the U.S. Energy Information released a report projecting that by 2040, world energy consumption will have grown by 48% from 2012 levels.  

That sounds like a terrific advancement for developing nations.  We worry about water in other countries, we worry about food, we worry about education and culture. Every single one of those is resolved with affordable energy. Energy is the great equalizer and America's second most important strategic resource after, obviously, food. 

Through new experiments involving the famous Schrödinger cat state paradox, researchers have shown that a "quantum cat" can be both alive and dead, and in two places at once.

The results, which involve inducing a large number of photons to have matching states (or to become entangled), show the ability to manipulate complex quantum states, with applications for computation and long-distance communication. They also represent perhaps the first time scientists have been able to achieve such quantum coherence at a macroscopic scale. 

Meerkats live in groups of up to 50 individuals, yet a single dominant pair will almost completely monopolise reproduction, while subordinates help to raise offspring through feeding and babysitting. Since only a small minority of individuals ever get to be dominants, competition for the breeding role is intense in both sexes and females are unusually aggressive to each other.

Within groups, subordinate females are ranked in a hierarchy based on age and weight, forming a "reproductive queue". When dominant females die, they are usually replaced by their oldest and heaviest daughter, though younger sisters sometimes outgrow their older sisters and can replace them in breeding queues.

In an article published online ahead of print on May 25, 2016 in Nature, investigators at the Medical University of South Carolina (MUSC) report that, during sensory stimulation, increases in blood flow are not precisely "tuned" to local neural activity, challenging the long-held view that vascular and local neural responses are tightly coupled.

Many brain-imaging techniques that rely on changes in the flow and oxygenation of blood--including functional magnetic resonance imaging (fMRI)--assume that vascular changes reflect a proportional change in local neural activity.

COLUMBIA, Mo. (May 25, 2016) - Approximately half of patients hospitalized with traumatic brain injuries are anemic, according to recent studies, but anemia's effects on the recovery of these patients is not clear. Now, researchers from the University of Missouri School of Medicine have found evidence that anemia can negatively influence the outcomes of patients with traumatic brain injuries.

Montreal, May 25, 2016 -- Humans aren't much different from other animals. Just like Pavlov's dogs, we can become conditioned to associate environmental cues with rewards. Innocent enough when the sight of your sneakers makes you want to go for a run, but not necessarily so when the sight of the liquor store prompts you to want a drink.

Indeed, Pavlovian cues that predict alcohol can lead us toward addiction. And sometimes those cues can become desirable in and of themselves, as shown in a new study published in Frontiers in Behavioral Neuroscience by researchers from Concordia University in Montreal.
