To understand the human brain, an international consortium of scientists has created the most complete atlas of this organ to date. The map reveals the anatomy, the architecture of the tissues, how or where each cell is, their function, gene expression and regulation. On Oct. 12, 2023, Science and Science Advances published a group of 21 studies that unveiled the map of the human brain, as well as the brains of nonhuman primates and mice, cell by cell, for an adult model and for the different stages of development.
The vast variety of tumors makes each cancer a world. For researchers, understanding the commonalities and divergences in their molecular underpinnings could help find successful treatments. Scientists from the Clinical Proteomic Tumor Analysis Consortium (CPTAC) have addressed these similarities and differences in 10 different types of cancer with two proteogenomic studies to unravel the genes that lead to cancer and the galaxy of interactions that regulate them.

Body mass index (BMI), which is calculated from height and weight, and its relationship to health is a hotly debated area of health. On the one hand, “it’s cheap, it’s intuitive, it’s noninvasive and easy to calculate,” Noa Rappaport told BioWorld. “But it misses a lot.” In the March 20, 2023, online issue of Nature Medicine, Rappaport’s group describes an alternative measure, which they have termed the biological BMI, that “better reflects metabolic health than traditional BMI,” said Rappaport, who is a senior research scientist at the Institute for Systems Biology and the paper’s corresponding author.
A study by researchers in Spain suggests that current metagenomic analyses of the microbiome can yield erroneous results, largely due to the incomplete databases that are used to identify microbial DNA sequences. A team led by Clemente Fernández Arias and Federica Bertocchini at the Centro de Investigaciones Biológicas Margarita Salas, Madrid, evaluated current microbiome analysis techniques on computer simulations of microbial communities in a report published on Feb. 8 in PLOS ONE.
A metabolite derived from the airway microbiome, indole-3-acetic acid (IAA), could become a potential therapeutic candidate for chronic obstructive pulmonary disease (COPD). Researchers at South China Normal University (SCNU) have shown how IAA prevents lung function decline by reducing inflammation, apoptosis and emphysema through IL-22 in the interaction between macrophages and alveolar epithelial cells.
Prognomiq Inc. nearly doubled its fundraising to date with a new $46 million financing to further develop its multiomics platform to detect cancer and other complex diseases earlier in their development. The financing led by Bruker Corp. along with new investor Catalio Capital Management brought total funds raised $101 million since the company’s founding in 2020.
Freenome Holdings Inc. has landed $290 million from Basel, Switzerland-based Roche Holding AG to advance its multiomics platform for early cancer detection. The multimillion financing deal brings San Francisco-based Freenome’s total funding to more than $1.1 billion, securing its status as a unicorn company. It comes on the heels of a series D raise in December 2021, which netted Freenome $300 million from investors including Perceptive Advisors and RA Capital Management.
Rebus Biosystems Inc. introduced the first commercially available spatial omics platform at the Advances in Genome Biology and Technology virtual meeting on March 1. The Rebus Esper builds on the company’s Synthetic Aperture Optics (SAO) technology that enables rapid quantitative analysis of tens of millions of cellular features across hundreds of thousands of cells in their native tissue contexts.
Bluestar Genomics Inc. and the University of Chicago revealed the publication of a genome-wide 5-hydroxymethylcytosine (5hmC) map across multiple human tissue types. In the report, published Dec. 2, 2020, in Nature Communications, the researchers detailed the development of the map by characterizing the genomic distributions of 5hmC in 19 human tissues derived from 10 organ systems.
