Scientists use DNA origami to alter gene expression in plants

April 4, 2019

DNA origami could change the way we alter plants

new research reported from the lab of Markita Landry, a professor of chemical and biomolecular engineering at UC Berkeley, a team of scientists has taken an original approach of using DNA origami nanotechnology to slip through plant cell walls and graft small interfering RNA (siRNA) directly onto plant cells. Their research shows it is possible to directly silence genes in plants without damaging plant tissues, and without making any alterations to the plant’s genome.

Testing the water harvester

The International Union of Pure and Applied Chemistry (IUPAC) has released the results of its first search for the Top Ten Emerging Technologies in Chemistry. Initiated as a special activity in honor of IUPAC’s 100th anniversary this year, the results have been published in the 2019 April-June 2019 issue of Chemistry International. Research from the lab of Omar Yaghi on water harvesting from desert air technology has been featured as one of the top 10.

Scientists discover hydration is key to improving catalyst performance for industrial use

NanoEP experiment

Scientists have used neutron scattering to identify the secret to a metal-organic framework's (MOF) ability to efficiently convert chemicals, through a process called catalysis, into new substances. By probing a material known as MOF-808-SO4, the team discovered molecular behavior that causes the catalyst to become less acidic, which could slow down the catalytic process vital in making products such as plastics, fragrances, cosmetics, flame retardants and solvents.
