Candidate Bioinks for Extrusion 3D Bioprinting—A Systematic Review of the Literature

PurposeOur aim was to identify biomaterials that have been found to be suitable for extrusion 3D bioprinting, outline their biomechanical properties and biocompatibility towards their application for bioprinting specific tissue types. This systematic review provides an in depth overview of current biomaterials suitable for extrusion to aid bioink selection for specific research purposes and facilitate design of novel tailored bioinks

New archaeological discoveries in north-central Timor-Leste indicate sociocultural adaptations to landscape change during the Holocene

During the Holocene, Wallacea saw dramatic sociocultural changes during the Pre-ceramic, Neolithic, Metal-age, and Colonial periods, as well as climatic and associated environmental changes that affected the landscapes and ecologies of islands. These environmental and cultural processes appear to have influenced human socioeconomic adaptations throughout the archipelago. Here, we present new anthropological and archaeological data demonstrating the effects of these processes. Excavations at the cave site of Hatu Saur on the north coast of Timor-Leste have revealed a deep archaeological sequence that dates from ca. 10,500 years until the present. The site contains extensive assemblages of faunal remains, as well as stone artifacts, revealing settlement patterns that were influenced by sea level change and estuarine infilling after 7 ka. The sequence encompasses the beginning of the Neolithic in Timor-Leste, some 3500 years ago, and the period from ca. 700 years ago when outside influences, including Chinese and Makassar traders and Dutch and Portuguese colonization, greatly affected the indigenous culture and economy on the island of Timor, reflected in the material culture remains from Hatu Saur. The archaeological findings complement related anthropological research in the region that highlights unique local mythologies of settlement origins and their contested histories

Primordial black holes with an accurate QCD equation of state

Making use of definitive new lattice computations of the Standard Model thermodynamics during the quantum chromodynamic (QCD) phase transition, we calculate the enhancement in the mass distribution of primordial black holes (PBHs) due to the softening of the equation of state. We find that the enhancement peaks at approximately 0.7 M-circle dot, with the formation rate increasing by at least two orders of magnitude due to the softening of the equation of state at this time, with a range of approximately 0.3 M-circle dot <M <1.4 M-circle dot at full width half-maximum. PBH formation is increased by a smaller amount for PBHs with masses spanning a large range, 10(-3) M-circle dot <M-PBH <10(3) M-circle dot, which includes the masses of the BHs that LIGO detected. The most significant source of uncertainty in the number of PBHs formed is now due to unknowns in the formation process, rather than from the phase transition. A near scale-invariant density power spectrum tuned to generate a population with mass and merger rate consistent with that detected by LIGO should also produce a much larger energy density of PBHs with solar mass. The existence of BHs below the Chandresekhar mass limit would be a smoking gun for a primordial origin and they could arguably constitute a significant fraction of the cold dark matter density. They also pose a challenge to infiationary model building which seek to produce the LIGO BHs without overproducing lighter PBHs.Peer reviewe
