Exploring molecular boundaries in DNA
It's important to be well organized. And this is especially true for the genome—the entirety of an organism's genetic information, also known as DNA. The genomic DNA is several meters long but has to fit inside the cell's nucleus, which has a diame.....»»
Exploring the effect of ring closing on fluorescence of supramolecular polymers
In supramolecular chemistry, the self-assembly state of molecules plays a significant role in determining their tangible properties. Controlling the self-assembled state has garnered significant attention as it can be exploited to design materials wi.....»»
Chemists create an emission molecular thermometer
Future technologies rely on phenomena that were previously considered the exclusive domain of theoretical physics or chemistry. For example, the approach to devices with high-density information storage arose when chemists discovered single-molecule.....»»
Light duty: Distinct molecular pathways control growth, flowering in plants
It's well known that plants have a fine-tuned ability to sense changes in the season by how much daylight they're exposed to, yet scientists observed more than a century ago that plants sometimes grow during one season and flower in another. Most res.....»»
Here are the 20+ states exploring support for Apple’s digital IDs in Wallet feature
One of the most highly anticipated features announced at WWDC back in 2021 was support for storing IDs in the Apple Wallet application. Touted by Apple as the last step before you are “fully free of your physical wallet,” the feature is still onl.....»»
Pioneering technique reveals new layer of human gene regulation
A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows......»»
Scientists develop new molecular system made from abundant element manganese for photooxidation
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All.....»»
Assessment and strategies for sustainable food systems within planetary boundaries
Since the Green Revolution in the 1960s, intensive agricultural production practices have laid the foundation for food security. However, these measures are also accompanied by significant resource input and environmental impacts. Meeting the increas.....»»
