May 10, 2016 — Bioengineers have converted a protein pathway found in freshwater photosynthetic bacteria into the first engineered transcriptional regulatory tool that is activated exclusively by UV-violet light. ... read more

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

Unlocking the Secrets of Squid Sucker Ring Teeth

Feb. 29, 2016 — A squid has more in common with a spider than you may think. The razor-sharp 'teeth' that ring the suckers found on some squid tentacles are made up entirely of proteins remarkably similar ... 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

Feb. 24, 2016 — Just like other crops, trees can also be genetically modified in order to introduce new, useful characteristics. Although such trees offer many socio-economic and environmental benefits, complex and ... read more

Feb. 22, 2016 — Scientists have known for years that bacteria have the ability to fight off invading viruses but considered their immune systems to be relatively primitive. However, a new discovery in recent years ... read more

Feb. 19, 2016 — A new microfluidic device may help scientists quickly home in on the electric field 'sweet spot' -- the range of electric potentials that will harmlessly and temporarily open up membrane ... read more

Genetically Modified Technology a Safe Tool to Help Meet Food Supply Demands, Plant Scientists Say

Feb. 18, 2016 — More than 1,000 scientists from nonprofit, corporate, academic, and private institutions say that public doubts about genetically modified food crops are hindering the next Green ... read more

Feb. 18, 2016 — Researchers have spent decades trying to replace the insulin-producing pancreatic cells, called beta cells, that are lost in diabetes. Now researchers have discovered that tissue from the lower ... 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

Feb. 15, 2016 — Light can be used to control the transport of proteins from the cell nucleus with the aid of a light-sensitive, genetically modified plant protein. Biologists working in the field of optogenetics ... read more

Breaking Cell Barriers With Retractable Protein Nanoneedles

Feb. 11, 2016 — Researchers have adapted a retractable protein polymer -- found naturally in certain bacteria -- to mechanically rupture cell membranes, which could lead to new drug delivery methods and other ... read more

Feb. 4, 2016 — New research identifies two new enzymes in bacteria that help fight off infection at a later stage, after an invading virus has already begun to replicate. The enzymes are part of the CRISPR-Cas ... 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

Cells from Cow Knee Joints Used to Grow New Cartilage Tissue in Laboratory

Jan. 21, 2016 — In an effort to develop a method for cartilage tissue engineering, researchers have successfully used cartilage cells from cow knee joints. By creating a successful method with conditions conducive ... read more

Fatty Acids from Genetically Modified Oilseed Crops Could Replace Fish Oil

Jan. 20, 2016 — Oil from genetically modified (GM) oil seed crops could replace fish oil as a primary source of the beneficial omega 3 fatty acid EPA, according to new research. Researchers studied the effect in ... read more

Gene Editing Technique Improves Vision in Rats With Inherited Blindness

Jan. 8, 2016 — A new technique that has the potential to treat inherited diseases by removing genetic defects has been shown for the first time to hinder retinal degeneration in rats with a type of inherited ... read more
