Scientists Uncover Genetic Secrets of Jonathan the Giant Tortoise's Extreme Longevity

Scientists Uncover Genetic Secrets of Jonathan the Giant Tortoise's Extreme Longevity

Scientists have analyzed the DNA of Jonathan, an Aldabra giant tortoise estimated to be 194 years old, making him the world's oldest known land animal. The research, published in the journal Science Advances, identified 287 unique gene variants in Jonathan that contribute to his extended lifespan by reducing the typical effects of aging. These genes are involved in crucial bodily processes such as inflammation reduction, insulin regulation, DNA damage repair, and cancer suppression. The study also compared Jonathan's epigenome, which controls gene activation, with that of younger Aldabra giant tortoises. Researchers found that the genetic switches regulating Jonathan's DNA repair and metabolism genes remained remarkably similar to those in younger tortoises, a key factor in his longevity. This marks the first time a giant tortoise's epigenome has been investigated, building upon previous genome analysis of Lonesome George, another long-lived tortoise.

European Commission Funds GENCODE with €19 Million, Bolstering Critical Biodata Infrastructure

European Commission Funds GENCODE with €19 Million, Bolstering Critical Biodata Infrastructure

The European Commission has announced a €19 million funding initiative for GENCODE, a globally recognized biodata resource that serves as the reference map for human and mouse genes. This financial commitment underscores the Commission's view of GENCODE as critical infrastructure for the European Union's economic security. GENCODE, which has been primarily funded by the U.S. National Institutes of Health since 2003, is one of 52 officially recognized global core biodata resources and the only one hosted in Spain, sharing responsibility with the UK and the United States. The funding, allocated for five years, aims to ensure the long-term sustainability, technical maintenance, and service continuity of this vital resource. The project is currently managed by EMBL’s European Bioinformatics Institute (EMBL-EBI) in Cambridge, UK, in collaboration with the Centre for Genomic Regulation (CRG) in Barcelona, and involves an international consortium including research groups from MIT, Yale, Stanford, the University ...

Tennessee Oncology Physician Contributes to Landmark Longevity Research on Giant Tortoise

Tennessee Oncology Physician Contributes to Landmark Longevity Research on Giant Tortoise

Dr. Yanjun Ma, a medical oncologist and researcher at Tennessee Oncology, has contributed to groundbreaking research published in Science Advances. The study examines the genetic and epigenetic characteristics of Jonathan, a 194-year-old giant tortoise, believed to be the world's oldest known living land animal. Researchers identified 287 unique genetic variants linked to biological processes that may explain Jonathan's extraordinary longevity and resistance to age-related diseases, including cancer. Dr. Ma specifically analyzed Jonathan's epigenome, which involves chemical modifications regulating gene expression without altering the underlying DNA sequence. This investigation aims to understand how giant tortoises maintain cellular health and suppress cancer over nearly two centuries, providing insights into extreme longevity.

U.S. Government and Tech Giants Invest $1.8 Billion in AI for Biological Research

U.S. Government and Tech Giants Invest $1.8 Billion in AI for Biological Research

The U.S. government, in collaboration with technology companies Meta Platforms and Alphabet, is partnering with the nonprofit Biohub to create extensive open datasets for training advanced AI models in biological research. This initiative has garnered a total investment of $1.8 billion. Meta Platforms, Google DeepMind, and drug discovery startup Isomorphic Labs are contributing $300 million. Concurrently, the Department of Energy is committing over $500 million across five years for laboratory measurement, modeling, and computation. The National Institutes of Health will coordinate existing repositories and open datasets, established with over $500 million in previous federal grants, which Biohub will standardize for AI model training. These new pledges build upon a prior $500 million investment made by Biohub in April. The project, known as the Virtual Biology Initiative, aims to observe and measure cellular responses to environmental changes across a vast range of conditions, far exceeding previous studi...

U.S. Scientists Rejuvenate Human Cells Using Chemical Compounds Without DNA Rewriting

U.S. Scientists Rejuvenate Human Cells Using Chemical Compounds Without DNA Rewriting

Scientists in the United States, led by David Sinclair's team, have successfully used chemical compounds to restore some molecular characteristics of younger cells in aging human cell cultures. The experiment, conducted in a laboratory setting, involved testing 80 combinations of compounds, ultimately narrowing down to six chemical cocktails. These compounds were found to alter gene-expression patterns in a way that reversed age-related changes, specifically improving nucleocytoplasmic compartmentalization, a process that deteriorates with age. The research focused on partial reprogramming, aiming to return cells to a younger state while preserving their original specialization, rather than completely reprogramming them into induced pluripotent stem cells. This approach avoids the risks associated with full reprogramming, such as loss of cellular identity and uncontrolled growth. The most significant finding was that some combinations reduced the estimated chronological age of cells by more than three year...
