Researchers are first to see DNA 'blink'
Feb 17, 2017
Many of the secrets of cancer and other diseases lie in the cell's nucleus. But getting way down to that level—to see and investigate the important genetic material housed there—requires creative thinking and extremely ...
Father's diet impacts on son's ability to reproduce, study finds
Feb 17, 2017
New research involving Monash University biologists has debunked the view that males just pass on genetic material and not much else to their offspring. Instead, it found a father's diet can affect their son's ability ...
Nanoparticle screen could speed up drug development
Feb 08, 2017
Many scientists are pursuing ways to treat disease by delivering DNA or RNA that can turn a gene on or off. However, a major obstacle to progress in this field has been finding ways to safely deliver that genetic material ...

A Czech-German team of researchers around Dr. Václav Mahelka from the Institute of Botany of the Czech Academy of Sciences and Dr. Frank Blattner from the Leibniz-Institute of Plant Genetics and Crop Plant Research (IPK) ...
A new path to fixing genes in living organisms
Jan 30, 2017
A unique gene-editing method that efficiently inserts DNA into genes located in dividing and non-dividing cells of living rats has been developed by a team of international researchers, including scientists from KAUST.
Rock samples suggest oxygen levels during 'Lomagundi Event' were high enough to support life development progress
Jan 17, 2017 report
(Phys.org)—A small team of researchers in the U.S. has found evidence in rock samples that suggests that oxygen levels during the Lomagundi Event were high enough to support the advancement of life on Earth. In their paper ...
A compact chip realizing highly precise simultaneous single-cell analysis of 100 cells
Dec 16, 2016
Hitachi announced the development of a compact 1-mm square chip that can efficiently analyze small amounts of various genetic material, specifically mRNA, expressed from DNA with high precision. The chip is able to precisely ...

Bacteria able to shed their cell wall assume new, mostly spherical shapes. ETH researchers have shown that these cells, known as L-forms, are not only viable but that their reproductive mechanisms may even correspond to those ...
Experiences leave behind epigenetic traces in our genetic material
Dec 07, 2016
An ideological dispute is taking place in biology. And it's about a big topic that's central to everything: heredity. In his epoch-making book On the Origin of Species of 1859, Darwin wrote of the reigning ignorance about ...
Bacteria produce aphrodisiac that sets off protozoan mating swarm
Dec 06, 2016
Researchers seeking the evolutionary roots of the animal kingdom have discovered a bacterium, Vibrio fischeri, that acts as an aphrodisiac by releasing an enzyme that sends the choanoflagellate, Salpinogoeca rosetta, one ...
