    1. In the present study, we describe the clinical course and provide a molecular analysis of another 25 mainland Chinese patients with IOPD, and we identified c.2662G > T (p.Glu888X) as the most common mutation in northern Chinese patients. These data collectively lay a foundation for understanding the clinical and genetic features of mainland Chinese patients with IOPD.

      GroupGenotypingMethod: genomic DNA extracted from peripheral blood leukocytes from patients and their parents. Exonic and flanking intronic regions of the MUT gene were amplified through PCR. PCR products were sequenced directly using forward and reverse primers on ABI 3700 sequencer. Mutation analysis using MUT reference NM_000255.3. Nucleotide numbering reflects cDNA numbering (initiation codon= codon1). All detected mutations were confirmed in the patients' parents. Novel variants were screened in 100 alleles from 50 control children. Novel variants were considered pathogenic when predicted to be deleterious by two algorithms.

    1. All nine affected individuals presented with various skeletal dysplasias. In four families (A and C–E), X-rays revealed severe platyspondyly leading to disproportionate stature (Figure 1). Lumbar gibbus and kyphoscoliosis were observed in families C and D, respectively. Three individuals (from families D and E) had cervical malformations and a hypoplastic odontoid peg with cervical instability. Short stature was also present in families A and B but appeared to be the result of limb shortening. Metaphyseal abnormalities of the long bones were found in families A and E, whereas families B–D showed epiphyseal abnormalities (Figure 1). Brachydactyly was observed in affected individuals from families A, B, and D. In addition to showing skeletal abnormalities, all affected individuals in families B and C had intellectual disability (ID). This could not be assessed for individuals A:II-1, E:II-1, and E:II-2 because of their early death at 7 weeks, 6 months, and 10 months of age, respectively. Both siblings of family B were severely disabled and unable to speak and are currently wheelchair bound. Dysmorphic facial features were non-discriminatingly mild but included coarse facial features, a prominent nose, and full cheeks in almost all affected individuals (Figure S1). A single palmar crease was also observed in six of nine affected individuals. A striking phenotype present in three of the five families was T-cell-negative SCID. Affected individuals from families A and B showed a lack of T cells, whereas B cell numbers were normal (Figure 4). Family E showed idiopathic CD4+ lymphopenia and an absolute lack of naive T cells (both CD4+CD45RA+ and CD8+CD45RA+ T cells were missing). In families B and E, a typical skin rash prompted further evaluation of the blood cells. Maternal T cells were excluded, and the oligoclonal T cell reaction found in the presence of eosinophilia was compatible with an Omenn-like presentation of SCID.1,2 Worth mentioning are also the liver cysts seen in affected individuals from families A and E. Although the phenotypes were widely variable and partly contrasting (e.g., severe versus no ID, severe versus mild platyspondyly, and epiphyseal versus metaphyseal changes), all major malformations and features occurred in three organ systems only: the immune system, the skeleton, and the neurological system. All together, we classify these five families as having phenotypic variability of an EXTL3-related neuro-immuno-skeletal dysplasia phenotype. The affected individuals from families A and E died in early infancy, whereas the others are currently between 2 and 38 years of age. Individual III-1 from family D died at 30 years of age from a unknown cause. Table 1 gives an overview of the most affected organ systems in all affected individuals. Detailed case reports and clinical data for each affected individual can be found in the Supplemental Note.

      Case 1: Family A: AII-1, female

      Born at 37 weeks, consanguineous family, APGAR = 9, tachypnea developed shortly after birth. At 20 weeks, skeletal abnormalities and kidney and liver cysts were detected. Died at 7 weeks from renal insufficiency.

    1. The company reportedly has about 18 million verified users thus far, but many of them are people in developing nations who signed up because of the promise of Worldcoin, a cryptocurrency that has seemingly fallen out of World’s plans.

      This statement raises questions about the demographics of the users and the sustainability of the verification process, especially in relation to the promised cryptocurrency.

They are also more likely to distrust the government, media, science, and medicine. That pattern is reversed with regard to trust in Fox News and Donald Trump.

    1. Consider, as well, the extent to which the tools of abstraction are themselves tied up in the history of the trans-Atlantic slave trade. As the historian Jennifer L. Morgan notes in “Reckoning With Slavery: Gender, Kinship, and Capitalism in the Early Black Atlantic,” the fathers of modern demography, the 17th-century English writers and mathematicians William Petty and John Graunt, were “thinking through problems of population and mobility at precisely the moment when England had solidified its commitment to the slave trade.”Their questions were ones of statecraft: How could England increase its wealth? How could it handle its surplus population? And what would it do with “excessive populations that did not consume” in the formal market? Petty was concerned with Ireland — Britain’s first colony, of sorts — and the Irish. He thought that if they could be forcibly transferred to England, then they could, in Morgan’s words, become “something valuable because of their ability to augment the population and labor power of the English.”This conceptual breakthrough, Morgan told me in an interview, cannot be disentangled from the slave trade. The English, she said, “are learning to think about people as ‘abstractable.’

      This deserves to be delved into more deeply. This sounds like a bizarre stop on the creation of institutional racism.

      How do these sorts of abstraction hurt the move towards equality?

    1. Author Ted Mitchell is the President of the American Council on Education. The article outlines solid numbers of Higher Education demographics and the changes that have occurred over the years and what that means for the future of students, especially those who have lived their entire lives in a digital era. The article is a great approach to reflecting on the future of technology and questions we can answer in this area and is not so much a focus on certain technologies.

    1. It is crucial to address bias in predictive models, ensure the statistical significance of predictions beyond race, ethnicity, and socioeconomic status, and forbid the use of algorithms that produce discriminatory results.

      We should not look at predictors that will not help us to make accurate interventions. Statistics should not be used to support bias.

    1. Israel, the Jewish State, is predicated on a decisive and stable Jewish majority of at least 70 percent. Any lower than that and Israel will have to decide between being a Jewish state and a democratic state. If it chooses democracy, then Israel as a Jewish state will cease to exist. If it remains officially Jewish, then the state will face an unprecedented level of international isolation, including sanctions, that might prove fatal.
