   EXPANSION OF THE SAGITTAL SUTURE INDUCES PROLIFERATION OF SKELETAL STEM CELLS
   AND SUSTAINS ENDOGENOUS CALVARIAL BONE REGENERATION
   
   SignificanceThis work describes the discovery that an “activation” of a
   calvarial suture, in the form of a controlled mechanical expansion, can
   increase the number of calvarial skeletal stem cells (cSSCs) present in the
   suture and can, consequently, ...In newborn humans, and up to approximately 2
   y of age, calvarial bone defects can naturally regenerate. This remarkable
   regeneration potential is also found in newborn mice and is absent in adult
   mice. Since previous studies showed that the mouse ...

   BLOCKADE OF TRANS PD-L1 INTERACTION WITH CD80 AUGMENTS ANTITUMOR IMMUNITY
   
   PD-L1 interaction with CD80 can be in cis or in trans, but how PD-L1
   interacts with CD80 in vivo remains controversial. Specific blockade of cis
   PD-L1/CD80 interactions on APCs reduces tumor immunity, but the impact of
   general blockade of PD-...PD-L1 has two receptors: PD-1 and CD80. Previous
   reports assumed that PD-L1 and CD80 interacted in trans, but recent reports
   showed that only cis PD-L1/CD80 interactions existed, and prevention of cis
   PD-L1/CD80 interactions on antigen-presenting cells (...

   ORIGINS OF NARCISSISM IN CHILDREN
   
   Narcissistic individuals feel superior to others, fantasize about personal
   successes, and believe they deserve special treatment. When they feel
   humiliated, they often lash out aggressively or even violently.
   Unfortunately, little is known ...Narcissism levels have been increasing
   among Western youth, and contribute to societal problems such as aggression
   and violence. The origins of narcissism, however, are not well understood.
   Here, we report, to our knowledge, the first prospective ...

   BACTERIAL ORIGIN OF A KEY INNOVATION IN THE EVOLUTION OF THE VERTEBRATE EYE
   
   Since the time of Charles Darwin, explaining the stepwise evolution of the
   eye has been a challenge. Here, we describe the essential contribution of
   bacteria to the evolution of the vertebrate eye, via interdomain horizontal
   gene transfer (...The vertebrate eye was described by Charles Darwin as one
   of the greatest potential challenges to a theory of natural selection by
   stepwise evolutionary processes. While numerous evolutionary transitions that
   led to the vertebrate eye have been explained, ...
