Fossorial adaptations in African mole-rats (Bathyergidae) and the unique appendicular phenotype of naked mole-rats

The main ecological and morphological characteristics of African mole-rats studied here are presented in Table 1. Table 1 Digging mode, social system, family size (mean/max.), body mass (mean), and sample size (n) of African mole-rats (Bathyergidae) analyzed in this study. Comparative anatomy Humerus Both scratch-diggers and chisel-tooth diggers (except H. glaber) exhibit a similar humeral phenotype… Continue reading Fossorial adaptations in African mole-rats (Bathyergidae) and the unique appendicular phenotype of naked mole-rats

Effect of sample density in prompt γ-ray analysis

Effect of hydrogen content on sensitivity First, to confirm that the sensitivity of PGA changes with the hydrogen content instead of the effect of apparent neutron flux, the sensitivity was evaluated by simulation for different hydrogen contents using samples of the same density and different sizes. In simulation, Monte Carlo simulation code PHITS16 was used,… Continue reading Effect of sample density in prompt γ-ray analysis

Effects of sex, age, choice of surgical orthodontic treatment, and skeletal pattern on the psychological assessments of orthodontic patients

Participants Study participants included consecutively selected patients who received diagnoses on the basis of panoramic and cephalometric radiographs, dental casts, and psychological tests before edgewise treatment at the Department of Orthodontics at Kagoshima University Hospital, Kagoshima, Japan, from 2013 to 2021. Among these consecutive patients, those who met the inclusion and exclusion criteria were analyzed… Continue reading Effects of sex, age, choice of surgical orthodontic treatment, and skeletal pattern on the psychological assessments of orthodontic patients

Cell-free prototyping enables implementation of optimized reverse β-oxidation pathways in heterotrophic and autotrophic bacteria

r-BOX—a model system for optimization in vitro, in E.coli and in C. autoethanogenum The modular and cyclic nature of r-BOX provides access to hundreds of possible molecules, but tuning product selectivity remains a key challenge. To address this issue, we developed and used high-throughput cell-free prototyping via iPROBE to tailor product selectivity and enable in… Continue reading Cell-free prototyping enables implementation of optimized reverse β-oxidation pathways in heterotrophic and autotrophic bacteria

Jamming a terahertz wireless link

Single-tone jamming We first consider the consequences for Bob if Mallory attempts to jam his signal using a single-tone frequency, which may coincide with the center frequency of Alice’s spectrum or may be at a different frequency. In our experimental configuration (see Fig. 1), Alice transmits noncoherent 1.12 Gbps on–off keying (OOK)-modulated data at a carrier frequency… Continue reading Jamming a terahertz wireless link

how a special immune system protects our grey matter

The brain is the body’s sovereign, and receives protection in keeping with its high status. Its cells are long-lived and shelter inside a fearsome fortification called the blood–brain barrier. For a long time, scientists thought that the brain was completely cut off from the chaos of the rest of the body — especially its eager… Continue reading how a special immune system protects our grey matter

Robust derivation of transplantable dopamine neurons from human pluripotent stem cells by timed retinoic acid delivery

A 48-hour RA-pulse promotes rapid conversion of hPSCs into NSCs with midbrain-like identity To explore the activities of RA on hESCs directed to adopt a neural fate in response to dSMADi10, we treated cultures of the GMP-compliant hESC line HS980 grown under dSMADi-conditions with 200 nM all-trans RA for the first 1, 2, 3, or 4… Continue reading Robust derivation of transplantable dopamine neurons from human pluripotent stem cells by timed retinoic acid delivery
