Scientists have found a way to make single-celled bacteria behave like stem cells, differentiating into genetically unique individuals as they ... read more

Genetic Control for Major Agricultural Weeds?

Waterhemp and Palmer amaranth, two aggressive weeds that threaten the food supply in North America, are increasingly hard to kill with commercially available herbicides. A novel approach known as ... read more

'Semi-Synthetic' Bacteria Churn out Unnatural Proteins

Synthetic biologists seek to create new life with forms and functions not seen in nature. Although scientists are a long way from making a completely artificial life form, they have made ... read more

Microrobots to Change the Way We Work With Cellular Material

Scientists have developed a system in which moving patterns of light are used to control the activity of microrobots, which are programmed to 'scoop up' mammalian cells so that they can be isolated ... read more

Non-GM Produce Earns 'Halo Effect' Under New Labeling Laws

Consumers were more willing to buy unlabeled produce after being shown food tagged as ''genetically modified'' in a new study that comes two months before a new federal law, ... read more

New Method to Purify Cell Types to High Purity

Current biology research relies on the ability to purify cell types using antibodies or transgenic constructs. However, antibody availability is often limited, and genetic manipulation is labor ... read more

How Time Affects the Fate of Stem Cells

Scientists have discovered how temporal fluctuations in the levels of two transcription factors can push embryonic stems cells into becoming different cell ... read more

Researchers have engineered a plasmid to remove an antibiotic resistance gene from the Enterococcus faecalis bacterium, an accomplishment that could lead to new methods for combating antibiotic ... read more

Synthetic Biologists Extend Functional Life of Cancer Fighting Circuitry in Microbes

Bioengineers have developed a method to significantly extend the life of gene circuits used to instruct microbes to do things like produce and deliver drugs, break down chemicals and sense the ... read more

Revolutionizing the CRISPR Method

Researchers have refined the famous CRISPR-Cas method. Now, for the very first time, it is possible to modify dozens, if not hundreds, of genes in a cell ... read more

Research Team Redefines the Footprint of Viral Vector Gene Therapy

Building on a track record of developing adeno-associated viral (AAV) vectors as a groundbreaking clinical tool for gene therapy and gene editing, researchers report a more sensitive method for ... read more

Transformed Tobacco Fields Could Cuts Costs for Medical Proteins

A new study describes the first successful rearing of engineered tobacco plants in order to produce medical and industrial proteins outdoors in the field, a necessity for economic viability, so they ... read more

World First: Homing Instinct Applied to Stem Cells Show Cells 'Home' to Cardiac Tissue

In a world first, scientists have found a new way to direct stem cells to heart tissue. The findings could radically improve the treatment for cardiovascular disease, which causes more than a quarter ... read more

Scissors Get Stuck: Another Way Bacteria Use CRISPR/Cas9

Before humans repurposed it as a gene editing tool, CRISPR/Cas9 was a sort of internal immune system bacteria use to defend themselves against phages. Scientists have found that the ... read more

Take Two E. Coli and Call Me in the Morning

What if the bacteria in your daily probiotic were also able to detect diseases in the gut and indicate when something is awry? New research has created an effective, non-invasive way to quickly ... read more

Robot Arm Tastes With Engineered Bacteria

A robotic gripping arm that uses engineered bacteria to 'taste' for a specific chemical has been developed by engineers. The gripper is a proof-of-concept for biologically-based soft ... read more

New Study on Gene Editing in Wildlife Finds People Are Wary

The applications of CRISPR based genetic engineering tools range from changing colors in butterfly wings to developing gene therapies that might one day cure or prevent human diseases. Some ... read more

Scientists Chart Course Toward a New World of Synthetic Biology

A team has compiled a roadmap for the future of synthetic or engineering biology, based on the input of 80 leaders in the field from more than 30 institutions. The report provides a strong case that ... read more

New Gene Editor Harnesses Jumping Genes for Precise DNA Integration

Scientists have developed a gene-editing tool -- using jumping genes -- that inserts any DNA sequence into the genome without cutting, fixing a major shortcoming of existing CRISPR ... read more

Would You Eat Genetically Modified Food If You Understood the Science Behind It?

While genetically modified organisms (GMOs) are considered safe by an overwhelming majority of scientists, only about one third of consumers share that view. A team of psychologists and biologists ... read more

Major Stem Cell Discovery to Boost Research Into Development and Regenerative Medicine

A new approach has enabled researchers to create Expanded Potential Stem Cells (EPSCs) of both pig and human cells. The research has incredible potential for studying human development and ... read more

Edible Insects? Lab-Grown Meat? The Real Future Food Is Lab-Grown Insect Meat

Livestock farming is destroying our planet. It is a major cause of land and water degradation, biodiversity loss, acid rain, coral reef degeneration, deforestation -- and of course, climate change. ... read more

New Genetic Engineering Strategy Makes Human-Made DNA Invisible

Scientists have developed a new technique to genetically engineer bacteria by making human-made DNA invisible to a bacterium's defenses. In theory, the method can be applied to almost any type ... read more
