Why are some Interfaces in Materials Stronger than others?

Grain boundaries (GBs) are often the preferred sites for void nucleation in ductile metals. However, it has been observed that all boundaries do not contribute equally to this process. We present a mechanistic rationale for the role of GBs in damage nucleation in copper, along with a quantitative map for predicting preferred void nucleation at GBs based on molecular dynamics simulations in copp...

Human feelings: why are some more aware than others?

A recent article reports that human perception of heartbeat timing is mediated by right (non-dominant) anterior insular cortex, and that the activity and the size of this region is directly correlated with individuals' subjective awareness of inner body feelings and emotionality. These results support the somatic-marker hypothesis of consciousness (a modern successor to the James-Lange theory o...

Why some bird brains are larger than others

How does brain size and design influence the survival chances of a species? A large brain may contribute to an individual’s success irrespective of its detailed composition. I have studied the size and shape of cerebella in birds and looked for links between the bird’s cerebellar design, brain size and behavior. My results indicate that the cerebellum in large-brained birds does not scale unifo...

Widgets: why are some interventions better than others?

the broader context of service provision, it is important that this does not race ahead of clear prescribing policies, underpinned by pharmocoeconomic considerations. We agree with the respondents that since buprenorphine is more expensive than methadone, the pharmocoeconomic aspects of prescribing need rigorous investigation. Whilst the studies they cite provide preliminary evidence of equipoi...

Why are some STEM fields more gender balanced than others?

Women obtain more than half of U.S. undergraduate degrees in biology, chemistry, and mathematics, yet they earn less than 20% of computer science, engineering, and physics undergraduate degrees (National Science Foundation, 2014a). Gender differences in interest in computer science, engineering, and physics appear even before college. Why are women represented in some science, technology, engin...
