Apr. 24, 2015 — Stem cells naturally cling to feeder cells as they grow in petri dishes. Scientists have thought for years that this attachment occurs because feeder cells serve as a support system, providing stems ... read more

Apr. 24, 2015 — Researchers have discovered that the signalling route - a cascade activation of several molecules - triggered by the ATM protein regulates DNA repair during the production of spermatocytes by ... read more

Feb. 25, 2015 — A survey of rice, wheat, barley, fruit, and vegetable crops found that most mutants created by advanced genetic engineering techniques may be out of the scope of current genetically modified organism ... read more

Engineers Devise Genetic 'On' Switch Made Exclusively of RNA

Feb. 2, 2015 — Scientists have created a new 'on' switch to control gene expression -- a breakthrough that could revolutionize genetic engineering. The new genetic control mechanism is made exclusively of ... read more

Feb. 2, 2015 — Scientists have developed a molecular sensor to measure 'crowding' in cells, which reflects the concentration of macromolecules present. The sensor provides quantitative information on the ... read more

Feb. 4, 2015 — Plant biologists report that drought tolerance in plants can be improved by engineering them to activate water-conserving processes in response to an agrochemical already in use -- an approach that ... read more

Jan. 28, 2015 — A genetic blueprint for organelles that give simple cells new functions has been developed by scientists. A research team has refuted a long-held assumption in biology: The scientists have shown that ... read more

Jan. 21, 2015 — Scientists have genetically recoded a strain of E. coli to depend on a synthetic amino acid so the bacteria can't survive outside the lab. The E. coli were also made resistant to two ... read more

Jan. 21, 2015 — Scientists have devised a way to ensure genetically modified organisms can be safely confined in the environment, overcoming a major obstacle to widespread use of GMOs in agriculture, energy ... read more

New Device Allows for Manipulation of Differentiating Stem Cells

Jan. 13, 2015 — A new device creates nanopores in adherent cell membranes, allowing researchers to deliver molecules directly into the cells during differentiation. "The ability to deliver molecules into ... read more

GMOs With Health Benefits Have a Large Market Potential

Jan. 13, 2015 — Genetically modified crops with an increased vitamin and/or mineral content have large potential to improve public health, but their availability for consumers is still hampered, as a result of the ... read more

Can Returning Crops to Their Wild States Help Feed the World?

Dec. 16, 2014 — To feed the world's growing population -- expected to reach nine billion by the year 2050 -- we will have to find ways to produce more food on less farmland, without causing additional harm to ... read more

Dec. 15, 2014 — Squid, what is it good for? You can eat it and you can make ink or dye from it, and now a team of researchers is using it to make a thermoplastic that can be used in 3-D ... read more

Dec. 1, 2014 — Genome engineering with the RNA-guided CRISPR-Cas9 system in animals and plants is changing biology. It is easier to use and more efficient than other genetic engineering tools, thus it is already ... read more

Nov. 24, 2014 — Researchers have made great progress in recent years in the design and creation of biological circuits -- systems that, like electronic circuits, can take a number of different inputs and deliver a ... read more

Nov. 11, 2014 — Researchers have constructed the first gene network that can be controlled by our thoughts. Scientists have developed a novel gene regulation method that enables thought-specific brainwaves to ... read more

Nov. 6, 2014 — A team of scientists compared induced pluripotent stem cells and embryonic stem cells created using somatic cell nuclear transfer. They found that the cells derived from these two methods resulted in ... read more

Nov. 3, 2014 — Yeast geneticists report they have developed a novel tool -- dubbed 'the telomerator' -- that could redefine the limits of synthetic biology and advance how successfully living things can ... read more

Oct. 30, 2014 — Lab-grown tissues could one day provide new treatments for injuries and damage to the joints, including articular cartilage, tendons and ligaments. Cartilage, for example, is a hard material that ... read more

Oct. 29, 2014 — Scientists have created a new kind of ion channel based on short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, ... read more
