The Middle Pleistocene is a crucial time period for studying human evolution in Europe, because it marks the appearance of both fossil hominins ancestral to the later Neandertals and the Acheulean technology. Nevertheless, European sites containing well-dated human remains associated with an Acheulean toolkit remain scarce. The earliest European hominin crania associated with Acheulean handaxes are at the sites of Arago, Atapuerca Sima de los Huesos (SH), and Swanscombe, dating to 400–500 ka (Marine Isotope Stage 11–12). The Atapuerca (SH) fossils and the Swanscombe cranium belong to the Neandertal clade, whereas the Arago hominins have been attributed to an incipient stage of Neandertal evolution, toHomo heidelbergensis, or to a subspecies ofHomo erectus. A recently discovered cranium (Aroeira 3) from the Gruta da Aroeira (Almonda karst system, Portugal) dating to 390–436 ka provides important evidence on the earliest European Acheulean-bearing hominins. This cranium is represented by most of the right half of a calvarium (with the exception of the missing occipital bone) and a fragmentary right maxilla preserving part of the nasal floor and two fragmentary molars. The combination of traits in the Aroeira 3 cranium augments the previously documented diversity in the European Middle Pleistocene fossil record.

There is considerable variation in mid-late Pleistocene hominin paranasal sinuses, and in some taxa distinctive craniofacial shape has been linked to sinus size. Extreme frontal sinus size has been reported in mid-Pleistocene specimens often classified as Homo heidelbergensis, and Neanderthal sinuses are said to be distinctively large, explaining diagnostic Neanderthal facial shape. Here, the sinuses of fossil hominins attributed to several mid-late Pleistocene taxa were compared to those of recent H. sapiens. The sinuses were investigated to clarify differences in the extent of pneumatisation within this group and the relationship between sinus size and craniofacial variation in hominins from this time period. Frontal and maxillary sinus volumes were measured from CT data, and geometric morphometric methods were used to identify and analyse shape variables associated with sinus volume. Some mid-Pleistocene specimens were found to have extremely large frontal sinuses, supporting previous suggestions that this may be a diagnostic characteristic of this group. Contrary to traditional assertions, however, rather than mid-Pleistocene Homo or Neanderthals having large maxillary sinuses, this study shows that H. sapiens has distinctively small maxillary sinuses. While the causes of large sinuses in mid-Pleistocene Homo remain uncertain, small maxillary sinuses in H. sapiens most likely result from the derived craniofacial morphology that is diagnostic of our species. These conclusions build on previous studies to overturn long-standing but unfounded theories about the pneumatic influences on Neanderthal craniofacial form, whilst opening up questions about the ecological correlates of pneumatisation in hominins.

Abstract Background Platypnoea–orthodeoxia syndrome (POS) is an uncommon condition characterized by dyspnoea and arterial desaturation in the standing or sitting position that improves in the supine position. Case summary We report two cases of POS caused by an atrial septal defect (ASD) and a patent foramen ovale (PFO). Both cases reported a recent decrease in body weight of more than 10 kg in a short time period. Transoesophageal echocardiography (TOE) with agitated saline bubble study revealed and a large amount of contrast bubble through the ASD (Patient 1) or the PFO (Patient 2) from the right atrium to the left atrium in the sitting position. Both patients were diagnosed by the finding of positional dyspnoea and the results of TOE using agitated saline bubble contrast. Discussion Taken together, their presentations suggest that weight loss in a short time period could be a pathogenic factor for POS.

Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body size). Some analyses have observed that in at least a few anatomical regions modern humans today appear to have relatively low trabecular density, but little is known about how that density varies throughout the human skeleton and across species or how and when the present trabecular patterns emerged over the course of human evolution. Here, we test the hypotheses that (i) recent modern humans have low trabecular density throughout the upper and lower limbs compared with other primate taxa and (ii) the reduction in trabecular density first occurred in early Homo erectus, consistent with the shift toward a modern human locomotor anatomy, or more recently in concert with diaphyseal gracilization in Holocene humans. We used peripheral quantitative CT and microtomography to measure trabecular bone of limb epiphyses (long bone articular ends) in modern humans and chimpanzees and in fossil hominins attributed to Australopithecus africanus, Paranthropus robustus/early Homo from Swartkrans, Homo neanderthalensis, and early Homo sapiens. Results show that only recent modern humans have low trabecular density throughout the limb joints. Extinct hominins, including pre-Holocene Homo sapiens, retain the high levels seen in nonhuman primates. Thus, the low trabecular density of the recent modern human skeleton evolved late in our evolutionary history, potentially resulting from increased sedentism and reliance on technological and cultural innovations.

What makes a "religious" holiday? Does the combination of ritual, culture, and family custom all merge together to create "religion?" Does it even matter if the historical basis for religious stories are false? In this work of philosophical short story fiction, the spaceship computer AI wakes up a family in deep space hibernation to give them time to prepare for, and celebrate, Passover. There are many situations unique to being in space that must be overcome; determining the right time period when taking into consideration time dilation, not to mention missing ingredients for traditional foods. Also, they are short two people of the requisite ten and ask the computer AI to "convert" and serve the role of two additional Jewish people. Awkwardly, the computer reminds them that some of their traditional stories are not supported by archeological evidence. This all begs important questions about the complicated weaving of history, faith, culture, and family custom in religious ceremony.

In the paper we discussed and analyzed the issues that confront practicing orthopedists with the most mysterious and at the same time the most studied vertebral column lesion in children and adolescents - idiopathic scoliosis. Nowadays a great amount of information on its various aspects has been already accumulated, but a practical output in the form of a system of effective treatment has not been yet found and (we can’t even speak about) there is no speech at all about the prevention (prophylactic) of the disease (scoliosis). On the basis of the own many year’s experience with this category of patients and the results of a comprehensive multi-faceted survey, the authors acquired the right to form their own point of view on the etiology and pathogenesis of the three-plane deformation in orthograde human (homo erectus). In this paper, the authors present their reflections on the history of the study of scoliosis, the terminology, statistical indicators and the existing views on its origins. Concerning argumentation on the own findings (conclusions) and views on the disease the authors plan to tell in the following sections.
