In the study, published in the journal Cell, researchers analysed the DNA of 89 ancient humans who lived in the central Andes between 500 and 9,000 years ago, and compared it with the genetic diversity of present day occupants, to shed light on the genetic changes over time.
As the COVID-19 pandemic enters its third month, businesses in the United States are marketing unlicensed and unproven stem-cell-based "therapies" and exosome products that claim to prevent or treat the disease. In Cell Stem Cell on May 5, bioethicist Leigh Turner describes how these companies are "seizing the pandemic as an opportunity to profit from hope and desperation."

Some types of gut bacteria are better than others at stimulating certain immune cells, specifically CD8+ T cells. And while these CD8+ T cells normally help protect the body against cancer, overstimulating them may promote inflammation and exhaust the T cells — which can actually increase susceptibility to cancer, according to new mouse model study published in Cell Reports.

Their work is reported in the November online issue of Cell Chemical Biology. This newly discovered behavior could turn the chemical into potent breast cancer drugs
Glioblastomas are the most aggressive form of brain cancer - they grow and spread rapidly through the brain and are virtually impossible to eradicate, typically leading to death within one or two years of diagnosis. Scientists are constantly seeking more powerful targeted therapies, but so far without success — in part because glioblastomas are challenging to study in a laboratory setting.
Lab-grown brain organoids developed from a patient’s own glioblastoma, the most aggressive and common form of brain cancer, may hold the answers on how to best treat it. A new study in Cell from researchers at Penn Medicine showed how glioblastoma organoids could serve as effective models to rapidly test personalized treatment strategies.
