Mice with fewer insulin-signaling receptors don't live longer

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even ...

New method for studying gene activity developed

(PhysOrg.com) -- Researchers from UQ's Institute for Molecular Bioscience (IMB), Harvard University and RocheNimblegen Inc. have developed a new method for examining genetic information that reveals clues to understanding ...

Biologists uncover a novel cellular proofreading mechanism

(PhysOrg.com) -- To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are ...

Fish flu: genetics approach may lead to treatment

(PhysOrg.com) -- A research team at the National Institute of Standards and Technology (NIST) has provided the first look at a genetic structure that may play a critical role in the reproduction of the infectious salmon anemia ...

Process important to brain development studied in detail

Knowledge about the development of the nervous system is of the greatest importance for us to understand the function of the brain and brain disorders. Researchers at Uppsala University have examined the key step when genes ...

Researchers suspend, image single DNA molecules

(PhysOrg.com) -- Studying chemical modifications in the chromosomes of cells is akin to searching for changes in coiled spaghetti. Scientists at Cornell have figured out how to stretch out tangled strands of DNA from chromosomes, ...

Different paths to drug resistance in Leishmania

Two remarkable discoveries were today revealed by researchers into genome analysis of Leishmania parasites. These results uncovered a surprising level of variation at the genome structure level.
