Human-on-a-chip model tests cancer drug efficacy and toxicity for therapeutic index
A reconfigurable "body-on-a-chip" model could transform drug development by simultaneously measuring compound efficacy and toxicity, for both target cells and other organs, such as the heart and liver. These findings, published in Science Translational Medicine, demonstrate the ability of a body-on-a-chip model to truly revolutionize biomedical research and personalized medicine through more accurate and efficient preclinical testing without the use of animal studies.

Finding 'Nemo's' family tree of anemones
Thanks in part to the popular film Finding Nemo, clownfishes are well known to the public and well represented in scientific literature. But the same can't be said for the equally colorful sea anemones—venomous, tentacled animals—that protect clownfishes and that the fish nourish and protect in return. A new study published online this month in the journal Molecular Phylogenetics and Evolution takes a step to change that, presenting a new tree of life for clownfish-hosting sea anemones along with some surprises about their taxonomy and origins.

Your nose knows when it comes to stronger memories
Memories are stronger when the original experiences are accompanied by unpleasant odors, a team of researchers has found. The study broadens our understanding of what can drive Pavlovian responses and points to how negative experiences influence our ability to recall past events.

Narcissists and psychopaths: how some societies ensure these dangerous people never wield power
Throughout history, people who have gained positions of power tend to be precisely the kind of people who should not be entrusted with it. A desire for power often correlates with negative personality traits: selfishness, greed and a lack of empathy. And the people who have the strongest desire for power tend to be the most ruthless and lacking in compassion.

Spintronic memory cells for neural networks
In recent years, researchers have proposed a wide variety of hardware implementations for feed-forward artificial neural networks. These implementations include three key components: a dot-product engine that can compute convolution and fully-connected layer operations, memory elements to store intermediate inter and intra-layer results, and other components that can compute non-linear activation functions.
