Genes. Not important.
One of the great puzzles of evolutional biology is what induced certain living creatures to abandon solitary existence in favor of living in collaborative societies, as seen in the case of ants and other social, colony-forming insects. A major characteristic of so-called eusocial species is the division of labor between queens that lay eggs and […]

Cognitive ability. Longevity.
Investigators at The Feinstein Institute for Medical Research discovered dozens of new genetic variations associated with a person’s general cognitive ability. The findings, which were published online today in Cell Reports, have the potential to help researchers develop more targeted treatment for cognitive and memory disorders. “For the first time, we were able to use […]

Health. Disease. Blurry lines…
Our genome is made up of 20,000 genes, all of which may cause disease. At present, 4,141 genes have been identified as being responsible for genetic abnormalities, leaving around 16,000 genes with unknown implication in disease. Researchers from the University of Geneva (UNIGE), Switzerland, — working in collaboration with scientists from Pakistan and the USA […]

Mapping the genome. The illusion of “dimensions”…
Cells face a daunting task. They have to neatly pack a several meter-long thread of genetic material into a nucleus that measures only five micrometers across. This origami creates spatial interactions between genes and their switches, which can affect human health and disease. Now, an international team of scientists has devised a powerful new technique […]

Knowing. Bacteria’s memory (x 100). Humans…
Researchers have identified a mutation that prompts bacterial cells to acquire genetic memories 100 times more frequently than they do naturally. This discovery provides a powerful research tool and could bring scientists one step closer to developing DNA-based data storage devices. (1) We insist on making the cosmos a big computer. We want to make […]
