Researchers from the Institute of Deep-sea Science and Engineering (IDSSE) of the Chinese Academy of Sciences, in collaboration with the University of Pisa, Italy, and the National Institute of Water and Atmosphere Research, New Zealand, have now documented the world’s deepest and largest known aggregation of whale fossils and active whale-fall ecosystems. This deep-sea site, referred to as a “whale necropolis” due to its vast size, is located in the Diamantina Zone of the southeastern Indian Ocean and contains evidence of cetacean falls for at least 5.3 million years.
Conventional cancer treatments, such as chemotherapy, often lack specificity and can damage both cancerous and healthy cells, leading to severe side effects. With this in mind, researchers at Indian Institute of Technology Gandhinagar (IITGN) have developed DNA nanostructures called tetrahedrons and modified them by attaching a Vitamin E-derived molecule called alpha-tocopherol succinate (αT), which can disrupt vital functions inside cancer cells while acting protectively in healthy cells. By incorporating αT into the DNA tetrahedrons, the researchers significantly enhanced cellular uptake and improved anticancer efficacy, resulting in more selective and effective elimination of cancer cells.
• Published in Nature, the team led by Dr. Toni Gabaldón used the MareNostrum supercomputer to reconstruct the genetic origin of the last common ancestor of all eukaryotes—the cellular lineage to which animals, plants, fungi, and protists belong. • The study challenges the idea that cellular complexity emerged from a single evolutionary encounter, pointing instead to a gradual process of interactions among different microorganisms that lasted for millions of years. • The findings identify contributions from several bacteria, in addition to the one that gave rise to the mitochondria, and suggest that giant viruses may have acted as vehicles for genetic transfer.
The deep sea is a unique ‘evolutionary engine’ with one of the richest and most unexplored sources of genetic diversity on Earth, according to a major new study that has assessed its potential to transform biotechnology and DNA sequencing technologies.
