Pros and Cons of Mandatory GMO Labeling

Apr. 1, 2016 — Researchers have concluded that mandatory labeling of genetically modified foods is justified, based on an extensive review of international scientific and legal frameworks related to genetically ... read more

Mar. 24, 2016 — Two new gene modification methods have been developed: lsODN (long single-stranded oligodeoxynucleotide) and 2H2OP (two-hit two-oligo with plasmid). These methods use CRISPR (Clustered Regularly ... read more

Feb. 25, 2016 — Bioengineers have tweaked Escherichia coli genes so that they pump out thebaine, a morphine precursor that can be modified to make painkillers. The genetically modified E. coli produces 300 times ... read more

Punchy Proteins Could Help Advance Drug Delivery

Feb. 17, 2016 — Earth's critters have developed countless ways to survive. Some bacteria that live inside paramecia, which are tiny aquatic organisms, use a coiled protein ribbon that unfurls like a Chinese ... read more

Feb. 17, 2016 — Synthetic biologists are learning to turn microbes and unicellular organisms into highly productive factories by re-engineering their metabolism to produce valued commodities such as fine chemicals, ... read more

Virologists Investigating Novel Applications for Viruses

Jan. 26, 2016 — Viruses can be classified in a completely new way based on viral structures, new research suggests. A better understanding of how viruses work can help open up new applications for viruses in the ... read more

Exact Pol(e) Position -- Precisely Where the Polymerase Is Changed

Jan. 21, 2016 — A method for the thorough analysis of protein modifications has been developed by researchers who have mapped the phosphorylation sites of the RNA polymerase II enzyme, which is responsible for ... read more

Traveling Salesman Uncorks Synthetic Biology Bottleneck

Jan. 5, 2016 — A computer program has been created that will open a challenging field in synthetic biology to the entire world -- repetitive polypeptides. The freely available computer program based on the ... read more

Jan. 5, 2016 — A new study demonstrates the role of nanostructured biphasic morphology of segmental polyurethanes as a matrix signal for organization of endothelial cells into network ... read more

Bacterium Carrying a Cloned Bt-Gene Could Help Millions Infected With Roundworms

Dec. 18, 2015 — Intestinal nematodes and roundworms infect more than one billion people worldwide, leading to malnutrition and developmental problems. Now a team of researchers has successfully inserted the gene for ... read more

Bacteria Engineered With Synthetic Circadian Clocks

Dec. 10, 2015 — Many of the body's processes follow a natural daily rhythm or so-called circadian clock, so there are certain times of the day when a person is most alert, when the heart is most efficient, and ... read more

Dec. 2, 2015 — Adult stem cells in the gut are continually bombarded with signals - from diet, the microbiome, and from invading bacteria and other stressors. Do the cells regenerate or remain poised for future ... read more

DNA Sequences in GMOs: Largest Database Now Publicly Available

Nov. 26, 2015 — The JRC has published a new database, JRC GMO-Amplicons, which contains more than 240 000 DNA sequences appearing in genetically modified organisms (GMOs). It will help to verify the presence of ... read more

Gene Drive Reversibility Introduces New Layer of Biosafety

Nov. 16, 2015 — A research team demonstrates effective safeguarding mechanisms for working with gene drives and unveils a first-of-its-kind method for reversing the changes they ... read more

Nov. 9, 2015 — Using a high-tech imaging method, biomedical engineers were able to see early-developing cancer cells deeper in tissue than ever before with the help of a novel protein from a ... read more

Engineers Design Magnetic Cell Sensors

Nov. 2, 2015 — Engineers have designed magnetic protein nanoparticles that can be used to track cells or to monitor interactions within cells. The new "hypermagnetic" protein nanoparticles can be produced ... read more
