Elements heavier than zinc are synthesized through the rapid (r) and slow (s) neutron-capture processes. The main site of production of the r-process elements (such as europium) has been debated for nearly 60 years. Initial studies of trends in chemical abundances in old Milky Way halo stars suggested that these elements are produced continually, in sites such as core-collapse supernovae. But evidence from the...

A patent complaint that Segway filed with the US International Trade Commission in 2014 has resulted in a wide-ranging order banning "personal transporters" that infringe some of its patents.
On Wednesday, the ITC issued a general exclusion order banning several types of the self-balancing devices often called "hoverboards." The case could affect the whole market, since...
Report: Apple spending up to $600M on Google Cloud Platform, moving away from Amazon Web Services
Apple is stuck between two major competitors when it comes to obtaining cloud space. Historically, the iPhone maker has used Amazon Web Services and Microsoft Azure to store data and, while analysts have predicted it would turn away from AWS soon, heading over to Google didn’t quite...
Nuclear DNA sequences from the Middle Pleistocene Sima de los Huesos hominins
A unique assemblage of 28 hominin individuals, found in Sima de los Huesos in the Sierra de Atapuerca in Spain, has recently been dated to approximately 430,000 years ago. An interesting question is how these Middle Pleistocene hominins were related to those who lived in the Late Pleistocene epoch, in particular to Neanderthals in western Eurasia and to Denisovans, a sister group of Neanderthals...
Co-ordinated ocular development from human iPS cells and recovery of corneal function
The eye is a complex organ with highly specialized constituent tissues derived from different primordial cell lineages. The retina, for example, develops from neuroectoderm via the optic vesicle, the corneal epithelium is descended from surface ectoderm, while the iris and collagen-rich stroma of the cornea have a neural crest origin. Recent work with pluripotent stem cells in culture has revealed a previously under-appreciated level...
