New biologically derived metal-organic framework mimics DNA

10-Apr-2019

The field of materials science has become abuzz with "metal-organic frameworks" (MOFs), versatile compounds made up of metal ions connected to organic ligands, thus forming one-, two-, or three-dimensional structures. There is now an ever-growing list of applications for MOF, including separating ...

Intuition and failure as valuable ingredients in chemical research

Methodology to collect lessons learned from partially failed trials and incorrect hypotheses

07-Feb-2019

Researchers from the lab of NCCR MARVEL's deputy director Berend Smit and colleagues have developed a methodology for collecting the lessons learned from partially failed trials and incorrect hypotheses -- the experiments that didn't work. The researchers used machine learning to capture chemical ...

Chirality in 'real-time'

Circular dichroism in the deep ultraviolet

11-Jan-2019

In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like our hands. This property is known as "chirality" and molecules with different chirality are called enantiomers. Enantiomers can exhibit entirely ...

Tumors backfire on chemotherapy

03-Jan-2019

Some patients with breast cancer receive chemotherapy before the tumor is removed with surgery. This approach, called 'neoadjuvant' therapy, helps to reduce the size of the tumor to facilitate breast-conserving surgery, and can even eradicate the tumor, leaving few or no cancerous cells for the ...

Anti-aging molecule NAD+ gets a boost from blocking an enzyme

25-Oct-2018

Nicotinamide adenine dinucleotide (NAD+) is a major player in nutrition today. Studies have shown that NAD+ concentrations decrease during aging and that recovering the body's levels of NAD+ can prolong both health span and even life span, making it the focus of much research in nutritional ...
