3-D printing with plants

For centuries, cellulose has formed the basis of the world’s most abundantly printed-on material: paper. Now, thanks to new research at MIT, it may also become an abundant material to print with — potentially providing a renewable, biodegradable alternative to the polymers currently used in 3-D printing materials. “Cellulose is …

Accurately manipulate gene expression by light illumination

A Hokkaido University researcher has successfully developed a method to accurately manipulate gene expression by light illumination and demonstrated its usability by creating double-headed zebrafish. It has been difficult to freely manipulate the timing and duration of gene expression using existing gene manipulation technologies, which depend on organism’s gene regulating …

Synthetic nanoparticles achieve the complexity of bio molecules 

Chemists at Carnegie Mellon University have demonstrated that synthetic nanoparticles can achieve the same level of structural complexity, hierarchy and accuracy as their natural counterparts — biomolecules. The study, published in Science, also reveals the atomic-level mechanisms behind nanoparticle self-assembly. The findings from the lab of Chemistry Professor Rongchao Jin …

Insecticides mimic melatonin, creating higher risk for diabetes

Synthetic chemicals commonly found in insecticides and garden products bind to the receptors that govern our biological clocks, University at Buffalo researchers have found. The research suggests that exposure to these insecticides adversely affects melatonin receptor signaling, creating a higher risk for metabolic diseases such as diabetes. Published online on …
