The extent and nature of symbolic behavior among Neandertals are obscure. Although evidence for Neandertal body ornamentation has been proposed, all cave painting has been attributed to modern humans. Here we present dating results for three sites in Spain that show that cave art emerged in Iberia substantially earlier than previously thought. Uranium-thorium (U-Th) dates on carbonate crusts overlying paintings provide minimum ages for a red linear motif in La Pasiega (Cantabria), a hand stencil in Maltravieso (Extremadura), and red-painted speleothems in Ardales (Andalucía). Collectively, these results show that cave art in Iberia is older than 64.8 thousand years (ka). This cave art is the earliest dated so far and predates, by at least 20 ka, the arrival of modern humans in Europe, which implies Neandertal authorship.

Unlabelled: Nature has inspired and provided humans with ideas, concepts, and thoughts on design, art, and performance for millennia. From early societies when humankind often took shelter in caves, until today, many materials and colorants to express feelings or communicate with one another were derived from plants, animals, or microbes. In this manuscript, an overview of these natural products used in the creation of art is given, from paintings on rocks to fashionable dresses made from bacterial cellulose.

The sign language uses a combination of complex finger and wrist configurations. The frequency of use of a particular sign is highly dependent on its physiological difficulty. However, no method allows to quantify accurately this difficulty.

Objectives: We report the discovery and description of three human teeth from the Middle Paleolithic archaeological levels of Arbreda Cave (Serinyà, Catalonia, NE Iberian Peninsula).
Materials And Methods: The teeth, two molars (one right dm and one right M) from Level N (older than 120 kyr) and one P from Level J (dated between 71 and 44 kyr), were morphologically described based on microCT images and compared with Neanderthal and Homo sapiens specimens.
Results: The teeth belong to a minimum of three individuals: one adult and one infant from Level N and one juvenile from Level J.

Tumor recurrence, the Gordian knot of liver transplantation for malignancies, may be attributed to many parameters. The technique of the "classical" recipient hepatectomy is believed to be one of the potential reasons to cause tumor evasion because of the possible increase of circulating tumor cells, thus leading to an increased recurrent rate. On this background, the no-touch oncological recipient hepatectomy technique has been developed.

Chelicerae, the mouthparts of chelicerates, are essential for food processing. Particularly within harvestmen (Opiliones), some species have greatly elongated their tripartite chelicerae and utilize them for mating behavior, defense, and primarily for predation. We investigated two European species, Ischyropsalis muellneri and Ischyropsalis hellwigii, which occupy different niches (caves, forests), exhibit different feeding ecologies (opportunist, specialist), and first and foremost possess different chelicerae morphologies (long and thin, short and robust).
