Biological How unique are today’s temperatures?
A Reconstruction of Regional and Global Temperature for the Past 11,300 Years.  Marcott et al.
 
Today’s fossil fuel use drives a global climate experiment: how much will global temperatures rise as a result of carbon emissions? To answer this question, scientists need to understand processes that cause global temperatures to vary in the absence of emissions...

Biological Stop! Codon time!
Stop codon reassignments in the wild.  Ivanova et al.  
 
A central idea in genetics is that all microbes follow the same genetic code when producing proteins.  What happens when organisms start to use this universal vocabulary in a different way?  The authors of this paper...

Physical Twist and Shout
Artificial Muscles from Fishing Line and Sewing Thread. Haines et al.
 
Artificial muscles have many potential applications, such as muscle transplantation and use in humanoid robots, but are currently expensive and inefficient. Haines et al. found a way to decrease the cost of artificial muscle synthesis by designing them out of common, inexpensive...

Biological Shape Shifters of the Plant World
Leaf Shape Evolution Through Duplication, Regulatory Diversification, and Loss of a Homeobox Gene.  Vlad et al.
 
Why do different species look different?  The full answer generally involves complicated interactions of many genes, but some particular differences can be traced to a single gene or a single region of the...

Biological The original GPS: how we remember what happened where
Neural Activity in Human Hippocampal Formation Reveals the Spatial Context of Retrieved Memories.  Miller et al
 
Think about your childhood best friend. Do you remember when you first met? You might remember that you sat next to each other in class or in the lunchroom, or that you shared an interest in the same hobby, like riding bikes. If you went to the...

Biological Take more naps, become more attractive!
A Critical Period of Sleep for Development of Courtship Circuitry and Behavior in Drosophila.  Kayser et al.
 
In most animals, babies sleep more than adults. This is true in humans, mice, and even all the way down to fruit flies (Drosophila). The authors of this paper discovered that the reason newborn flies sleep more than adults is because they...

Biological Overcrowding in neuronal synapses
Composition of isolated synaptic boutons reveals the amounts of vesicle trafficking proteins. Wilhelm et al.
 
Sometimes we think of the brain as a large biocomputer, taking in information from our senses and sending commands to our body in return. But how does information get from one part of the brain to the other? Neurons pass electrical signals...

Biological How did dogs become our best friend?
Complete Mitochondrial Genomes of Ancient Canids Suggest a European Origin of Domestic Dogs.  Thalmann et al.
 
At some point in our lives, we have all had a friendship with a dog.  So did the generations before us, as well as the generation before them.  When, exactly, did the friendship between dogs and humans take shape?  Research in this paper...
