How RNA machinery navigates our genomic obstacle course
Once upon a time, scientists thought RNA polymerase—the molecule that kicks off protein synthesis by transcribing DNA into RNA—worked like a wind-up toy: Set it down at a start site in our DNA and it ...
Nanotech-enabled moisturizer speeds healing of diabetic skin wounds
A new high-tech but simple ointment applied to the skin may one day help diabetic patients heal stubborn and painful ulcers on their feet, Northwestern University researchers report.
Twins experiment reveals genetic link with mosquito bites
The likelihood of being bitten by mosquitoes could be down to our genes, according to a study carried out on twins.
Viral proteins may regulate human embryonic development
A fertilized human egg may seem like the ultimate blank slate. But within days of fertilization, the growing mass of cells activates not only human genes but also viral DNA lingering in the human genome from ...
Seeing the (UV) light: Previously undetected difference in human mutation rate unique to Europeans
DNA 'spool' modification affects aging and longevity
Research on a modified protein around which DNA is wrapped sheds light on how gene regulation is linked to aging and longevity in nematodes, fruit flies and possibly humans.
Sex offending may be in the genes but knowing that won't prevent it
A high-profile piece of research recently suggested that the sons and brothers of convicted sex offenders are more likely to be convicted of sex crimes than others. The implication is that the potential for ...
How to make trees grow bigger and quicker
Scientists at The University of Manchester have discovered a way to make trees grow bigger and faster, which could increase supplies of renewable resources and help trees cope with the effects of climate change.
First steps in basic biological process that could be harnessed to make therapeutic cells
Understanding the molecular signals that guide early cells in the embryo to develop into different types of organs provides insight into how tissues regenerate and repair themselves. By knowing the principles ...
Pulling the strings of our genetic puppetmasters: Engineers gain control of gene activity
Duke researchers have developed a new method to precisely control when genes are turned on and active.
DNA can't explain all inherited biological traits, research shows
Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows.
High fidelity: Researcher finds keys to genome integrity
Maintaining the stability and the correct sequence of our genetic information is vital to the accurate transmission of our genetic code. However, in the course of replicating, our DNA frequently runs into ...
Toward an expression atlas for an entire brain
Researchers who study how genes are expressed across a given tissue can now examine thousands of genes at once at cellular resolution, thanks to new methods developed at EMBL and published in Nature Biotechnology. The ne ...
Scientists uncover gene 'architects' responsible for body's blueprint
Researchers have identified two key proteins that act as genetic 'architects', creating the blueprint needed by embryos during the earliest stages of their development.
