Development-driven archaeology: bane or boon for bioarchaeology?
Summary. Through much of the world there is a move towards policies of in situ preservation of the buried archaeological heritage, typically supported by small-scale investigative excavations (often called 'evaluations'). In this review we attempt to judge the success of these policies in England and Wales, from the standpoint of bioarchaeology. We consider particularly the value of data for plant and insect macrofossils from trial excavations associated with development (a) in producing information which contributes towards research agendas, and (b) as a guide to the preservational condition of organic archaeological deposits

Bi-allelic TTI1 variants cause an autosomal-recessive neurodevelopmental disorder with microcephaly.
Telomere maintenance 2 (TELO2), Tel2 interacting protein 2 (TTI2), and Tel2 interacting protein 1 (TTI1) are the three components of the conserved Triple T (TTT) complex that modulates activity of phosphatidylinositol 3-kinase-related protein kinases (PIKKs), including mTOR, ATM, and ATR, by regulating the assembly of mTOR complex 1 (mTORC1). The TTT complex is essential for the expression, maturation, and stability of ATM and ATR in response to DNA damage. TELO2- and TTI2-related bi-allelic autosomal-recessive (AR) encephalopathies have been described in individuals with moderate to severe intellectual disability (ID), short stature, postnatal microcephaly, and a movement disorder (in the case of variants within TELO2). We present clinical, genomic, and functional data from 11 individuals in 9 unrelated families with bi-allelic variants in TTI1. All present with ID, and most with microcephaly, short stature, and a movement disorder. Functional studies performed in HEK293T cell lines and fibroblasts and lymphoblastoid cells derived from 4 unrelated individuals showed impairment of the TTT complex and of mTOR pathway activity which is improved by treatment with Rapamycin. Our data delineate a TTI1-related neurodevelopmental disorder and expand the group of disorders related to the TTT complex
