TALENs technology allows site-specific gene mutation and editing in living organisms
(Phys.org)—Iowa State University researchers are helping to advance new techniques that allow scientists to site-specifically mutate and edit the genes of living organisms.
Scientists uncover mechanism by which plants inherit epigenetic modifications
During embryonic development in humans and other mammals, sperm and egg cells are essentially wiped clean of chemical modifications to DNA called epigenetic marks. They are then held in reserve to await fertilization.
From vitro to vivo: Fully automated design of synthetic RNA circuits in living cells
Imaging metals within cells: Identifying the proteins that bind
(Phys.org)—Metals such as copper, zinc, and iron are important nutrients to all life. The special properties of these elements that make them so useful in technologies including batteries and catalysts ...
'Promiscuous' enzymes still prevalent in metabolism
Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from ...
Lessons from herbicide tolerance
(Phys.org)—Polyamines are widespread and important organic compounds involved in multiple cellular processes in living organisms. Their levels are highly regulated through a combination of processes including ...
Controlling cellular function on nano surfaces
EU-funded researchers applied nano-engineering to the creation and control of biological interfaces with natural and novel synthetic functionalities. The ultimate goal is the steering of cell function for ...
Cadherin-catenin-actin structure exerts force inside and between cells in living tissues, study shows
If you place certain types of living cells on a microscope slide, the cells will inch across the glass, find their neighbors, and assemble themselves into a simple, if primitive tissue. A new study at Stanford ...
Scientists say NASA's 'new arsenic form of life' was untrue
Two new scientific papers have disproved a controversial claim made by NASA-funded scientists in 2010 that a new form of bacterial life had been discovered that could thrive on arsenic.
Turning DNA into a hard drive
Silicon-based computers are fine for typing term papers and surfing the Web, but scientists want to make devices that can work on a far smaller scale, recording data within individual cells. One way to do that is to create ...
New technology speeds up DNA 'rewriting' and measures the effects of the changes in living cells
Our ability to "read" DNA has made tremendous progress in the past few decades, but the ability to understand and alter the genetic code, that is, to "rewrite" the DNA-encoded instructions, has lagged behind. A new Weizmann ...
Real-time monitoring of RNA splicing in living cells moves step closer with novel fluorescent probe
Numerous biological processes depend on molecules called lariat RNAs (LaRNAs). These lasso-shaped structures form in the cell during RNA splicing. During this process, transcribed RNA strands convert to messenger ...
Scientists find 'man's remotest relative' in lake sludge
After two decades of examining a microscopic algae-eater that lives in a lake in Norway, scientists on Thursday declared it to be one of the world's oldest living organisms and man's remotest relative.
Research finds bright future for alternative energy with greener solar cells
(Phys.org) -- Even alternative energy technologies can sometimes be a little greener, according to a Kansas State University graduate student's research.
