Have a great week and see you back here next weekend!

Ancient Hungarian Crypt Offers Clues to Tuberculosis Origins

As one of the leading infectious disease killers, Tuberculosis, a bacterial infection, holds interest for scientists who disagree over the origins of the human disease. However, a new study in Nature Communications uses a cutting-edge approach called metagenomics to analyze corpses that were naturally mummified in a Hungarian crypt. Of 14 genomes found in eight of the corpses, researchers discovered that multiple strains were circulating in Hungary in the 18th century when these people died.

The Toronto Star—“‘All the historic genomes belonged to lineages that we see today,” said senior author Dr. Mark Pallen, a professor of microbial genomics at the University of Warwick. “So TB hasn’t changed much in 200 years … (and) it turns out that the most common ancestor of the Euro-American lineage that all our (tuberculosis) genomes belonged to dates back to late Roman times.’”

Polio, Cancer—One Nemesis May Counter the Other

Tomorrow, April 12, is the 60th anniversary of when Dr. Jonas Salk’s polio vaccine was declared to be effective. Today, as the world inches closer to full polio eradication, interesting news highlighted on “60 Minutes” looks at the polio virus’ ability to kill another lethal illness—Cancer. A genetically engineered strain of polio virus appears to thwart lethal brain cancer tumors.

The Huffington Post—“The modified polio virus seems to deactivate the cancer tumor’s ability to defeat immune capacities. Freed up, the immune system works at defeating the tumor. Miraculously, the immunotherapy workings spare healthy tissues, while killing cancer cells.”
