Historical rice farming in China linked to contemporary polygenic score differences

Chen Zhu, Thomas Talhelm, Yingxiang Li, Gang Chen, Jiong Zhu & Jun Wang
Following domestication in the lower Yangtze River valley 9,400 years ago, rice farming spread throughout China and changed lifestyle patterns among Neolithic populations. Here we report evidence that the advent of rice domestication and cultivation may have shaped humans not only culturally but also genetically. Leveraging recent findings from molecular genetics, we construct a number of polygenic scores of behavioural traits and examine their associations with rice cultivation based on a sample of 4,101 individuals...

Moisture and mold-proof characteristics of surface modified wood for musical instrument soundboards

Caiping Xu, Zhenbo Liu, Wanli Li & Xingyun Li
Wood is the major material for musical instrument soundboards fabrication on account of practical and cultural reasons. However, as a natural material, wood is easy to be degraded due to moisture or fungi corrosion. The traditional wood protection methods are normally meant for the structural materials, which might not suitable for the soundboard materials. Therefore, in this work, a novel nanomaterial-based modification method was applied to effectively protect wood from moisture and fungi, without causing...

Comparative analysis of a geometric and an adhesive righting strategy against toppling in inclined hexapedal locomotion

Toni Wöhrl, Adrian Richter, Shihui Guo, Lars Reinhardt, Manuela Nowotny & Reinhard Blickhan
Animals are known to exhibit different walking behaviors in hilly habitats. For instance, cats, rats, squirrels, tree frogs, desert iguana, stick insects and desert ants were observed to lower their body height in traversing slopes, whereas mound-dwelling iguanas and wood ants tend to maintain constant walking kinematics regardless of the slope. This paper aims to understand and classify these distinct behaviors into two different strategies against toppling for climbing animals by looking into two factors,...

We predicted a network of regulatory targets and protein interaction partners of PPP1CB, and identified a PPI network consisting of 39 node genes....

Advanced Cambrian hydroid fossils (Cnidaria: Hydrozoa) extend the medusozoan evolutionary history

Xikun Song, Bernhard Ruthensteiner, Mingxin Lyu, Xi Liu, Jian Wang & Jian Han
Primitive cnidarians are crucial for elucidating the early evolution of metazoan body plans and life histories in the late Neoproterozoic and Palaeozoic. The highest complexity of both evolutionary aspects within cnidarians is found in extant hydrozoans. Many colonial hydrozoans coated with chitinous exoskeletons have the potential to form fossils; however, only a few fossils possibly representing hydroids have been reported, which still require scrutiny. Here, we present an exceptionally well-preserved hydroid found in the Upper...
