A team of researchers from Johns Hopkins Medical Campus, working with medical research company 10x Genomics has used a spatial gene expression technology to further define the six-layered human dorsolateral prefrontal cortex. In their paper published in the journal Nature Neuroscience, the group describes their use of the new technology and what it allowed them to see in their study of the dorsolateral prefrontal cortex.
An international team led by researchers at the Centre for Palaeogenetics in Stockholm has sequenced DNA recovered from mammoth remains that are up to 1.2 million years old. The analyses show that the Columbian mammoth that inhabited North America during the last ice age was a hybrid between the woolly mammoth and a previously unknown genetic lineage of mammoth. In addition, the study provides new insights into when and how fast mammoths became adapted to cold climate. These findings are published today (February 172021) in Nature.
Around one million years ago there were no woolly or Columbian mammoths, as they had not yet evolved. This was the time of their predecessor, the ancient steppe mammoth. Researchers have now managed to analyze the genomes from three ancient mammoths, using DNA recovered from mammoth teeth that had been buried for 0.7−1.2 million years in the Siberian permafrost.

A baby has been born following a uterus transplant for the first time ever in France, the hospital treating mother and infant said Wednesday. Such births are extremely rare but not unprecedented, and come after a cutting-edge procedure to transplant a healthy uterus into a woman whose own is damaged or missing. The baby, a girl weighing 1.845 kilogrammes (4.059 pounds), was born on Friday, according to the team at the Foch hospital outside Paris.

Imperial College expert warns new coronavirus wave could kill tens of thousands of Britons by late summer if lockdown is completely lifted too early.
Professor Azra Ghani revealed how a new model made at Imperial College London forecasts a wave of deaths by summer 2021 if restrictions are eased in July — even despite a successful vaccine rollout.

Regular and frequent blood glucose monitoring is vital in managing diabetes treatment plans and preventing severe complications. Because current invasive techniques impede patient compliance and are not infection-free, many noninvasive methods have been proposed. Among them, optical methods have drawn much attention for their rich optical contrast, but their resolution is degraded in deep tissue. Here, we present an ultrasound-modulated optical sensing (UOS) technique to noninvasively monitor glucose that uses an infrared laser (1645 nm) and a single-element focused ultrasound transducer. Focused ultrasound waves can acoustically localize diffused photons in scattering media, and thus optical contrast can be represented with much enhanced spatial resolution.
Non-invasive, early detection of invasive cancers — dr. patrizia paterlini-brechot, founder, rarecells diagnostics, ISET technology.
Dr. Patrizia Paterlini-Bréchot is a tenured Professor of Cell and Molecular Biology and Oncology at Paris Descartes University and head of a research team at the French National Institute of Health and Medical Research (INSERM).
Dr. Paterlini-Bréchot studied medicine at the University of Modena and Reggio Emilia, where she specialized in hematology and oncology. In 1988 she turned her focus on research in cell and molecular biology and published over 80 research articles and reviews in national and international scientific journals.
