☆ Atlas of cells offers a milestone leap in understanding of the human body

New research based on the findings, published in several papers Wednesday in Nature and its sister journals, represents a “leap in understanding of the human body,” according to the Human Cell Atlas consortium. Regev compared scientific knowledge of cell biology before the Human Cell Atlas initiative with a “15th century map.”“Now, years later, the resolution of the map is a lot higher,” she said. The cell atlas aims to fill in a missing link between genes, diseases and treatment therapies. During the Covid-19 pandemic, the Human Cell Atlas community used the available data to reveal that the nose, eyes and mouth were most vulnerable to infection. “It was only clear through the Human Cell Atlas data that those cells were … entry points before the virus continued into the internal organs.

☆ Did syphilis originate in the Americas? Ancient DNA offers some insight

In France, it was named the “Neapolitan disease” after the French army got infected during its invasion of Naples, Italy, in the first documented syphilis epidemic. A complex disease caused by a complex bacteriumWithout treatment, syphilis can cause physical disfigurement, blindness and mental impairment. Others believe T. pallidum bacteria always had a global distribution but perhaps grew in virulence after initially manifesting as a mild disease. Some bones had marks characteristic of infection with T. pallidum — the bacteria effectively eat away at bones, leaving concave lesions. “The modern tools available for extracting DNA from ancient samples, for enriching the treponemal DNA, and obtaining deep sequencing from samples has rapidly increased our understanding of the Treponema.”

☆ British scientists plan to expand genomic sequencing from COVID to flu

NEXU Science Communication/via REUTERSLONDON, Jan 10 (Reuters) - Genomic sequencing allowed the world to track new coronavirus variants throughout the pandemic. Now British researchers plan to use it to better understand a host of other respiratory pathogens, from influenza to respiratory syncytial virus (RSV). The work will begin later this year by using leftover material from swabs taken for COVID-19 diagnostic purposes, sequencing SARS-CoV-2, influenza, RSV and other common respiratory viruses in a combined process. While some of the viruses targeted typically cause mild, cold-like symptoms, others can cause serious illness, particularly in vulnerable populations. The five-year initiative aims to begin work from spring this year and is funded by Wellcome.

☆ Studiu: Noua tulpină de coronavirus depistată în Marea Britanie afectează mai mult tinerii sub 20 de ani

Aproape 27 de țări au raportat începând cu 30 decembrie cazuri de infecții cu noua variantă a coronavirusului, cea mai recentă fiind China, care a identificat o femeie în vârstă de 23 de ani, o studentă care s-a întors din Marea Britanie şi care a fost depistată pozitiv la Shanghai, la 14 decembrie. „Există un consens între toate analizele că VOC (noua variantă a COVID) are un avantaj substanțial de transmitere”, au constatat cercetătorii studiului. „Aceste analize au informat planificarea guvernului britanic în ultimele săptămâni și arată că noua variantă de COVID, B.1.1.7, are o transmisibilitate substanțial mai mare decât virusurile anterioare SARS-CoV-2 care circulă în Marea Britanie”, a spus profesorul Neil Ferguson de la Imperial College London. Cu toate astea, studiul relevă că deși persoanele cu vârsta sub 20 de ani reprezintă o proporție mai mare de cazuri din noua variantă a virusului, este prea devreme pentru a determina motivul. Deoarece noua variantă este mai ușor transmisibilă, va fi mai dificil de controlat, potrivit lui Ferguson, care a subliniat că utilizarea vaccinurilor trebuie să se facă cât mai repede posibil, scrie libertatea.ro.
