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.
New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking ...
Genetically speaking, mammals are more like their fathers
You might resemble or act more like your mother, but a novel research study from UNC School of Medicine researchers reveals that mammals are genetically more like their dads. Specifically, the research shows ...
Evolving a bigger brain with human DNA
The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger ...
Genetic evidence shows loss of three basic tastes in penguins
A University of Michigan-led study of penguin genetics has concluded that the flightless aquatic birds lost three of the five basic vertebrate tastes—sweet, bitter and the savory, meaty taste known as umami—more ...
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.
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 ...
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.
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.
The two faces of cellular forgetfulness
Ludwig Maximilian University researchers have monitored how epigenetic information is transmitted to daughter cells during cell division and determined when the cell's developmental memory is re-established.
New mechanisms of 'social networking' in bacteria
Bacteria have traditionally been viewed as solitary organisms that "hang out on their own," says molecular biologist Kevin Griffith of the University of Massachusetts Amherst. However, scientists now realize ...
