[ad_1] Leonardo da Vinci is famous for his elaborate and nuanced works of art and advanced technological ideas. But new research has revealed another level of complexity to his designs: a hidden world of tiny life forms on his artwork. The findings, the researchers said, could help build a “catalog” …

[ad_1] Scientists have developed a new therapy that they believe can actually reverse aging at the genetic level. By breathing pure oxygen into a hyperbaric chamber five days a week for three months, the team were able to effectively reverse the age of chromosomal telomeres. More research is obviously needed …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 19, 2020 Scientists from Utah have discovered new functions of a key cellular machine that regulates the packaging of genes and is mutated in 20% of human cancers. The study was published today in print in the journal Molecular cell. Genes are segments of …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 19, 2020 Tel Aviv University (TAU) researchers have shown that the CRISPR / Cas9 system is highly effective in treating metastatic cancers, a significant step on the road to finding a cure for cancer. Researchers have developed a new lipid nanoparticle-based delivery system that …

[ad_1] If you’ve ever studied chemistry or biology, there’s a very good chance you’ve come across the common pictorial representation of what a chromosome should look like. As millions of high school and college students attest, it is a tall, narrow X shape, displaying the appearance of two chromatids joined …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 18, 2020 For a slow-growing microbe that multiplies infrequently, Mycobacterium tuberculosis, the pathogen that causes tuberculosis (TB) has long puzzled researchers as to how it develops resistance to antibiotics so quickly, within weeks or months. Now, TB researchers at San Diego State University have …

[ad_1] (Illustration by Wendolyn Hill) The era of functional genomics has allowed scientists to analyze huge amounts of data on cellular activity in disease and health. The more this data is shared between labs, the more power scientists have to find disease-related genes. This widespread sharing of functional genomics data, …

[ad_1] UW Medicine researchers at Seattle’s Brotman Baty Institute have created two cell atlases that track gene expression and chromatin accessibility during the development of human cell types and tissues. An atlas maps gene expression within single cells in 15 fetal tissues. The second atlas maps the chromatin accessibility of …
