A team of bioengineers and biomedical scientists from the University of Sydney and the Children's Medical Research Institute (CMRI) at Westmead have used 3D photolithographic printing to create a complex environment for assembling tissue that mimics.....»»
The link between the impact of radiation on DNA and the time in which the damaged molecule breaks irreversibly revealed
We are exposed to ionizing radiation more often than we think: when we bathe in the sun, which emits UV rays, or when we get X-rayed. Even when we are traveling on an intercontinental flight, which reaches 10,000 meters above sea level. This type of.....»»
Small-molecule autocatalysis may have paved the way for the emergence of evolution by natural selection
The discipline of systems chemistry deals with the analysis and synthesis of various autocatalytic systems and is therefore closely related to the study of the origin of life, since it investigates systems that can be considered as a transition betwe.....»»
Quantum material exhibits "non-local" behavior that mimics brain function
We often believe computers are more efficient than humans. After all, computers can complete a complex math equation in a moment and can also recall the name of that one actor we keep forgetting. However, human brains can process complicated layers o.....»»
Researchers discover antifungal molecule
Fungal infections are killing thousands of Americans each year, some with a morbidity rate of nearly 80%. To make matters worse, only a handful of antifungal treatments are available, and even those are becoming less effective as fungi become more re.....»»
Researchers use quantum circuit to identify single nucleotides
DNA sequencing technology, i.e., determining the order of nucleotide bases in a DNA molecule, is central to personalized medicine and disease diagnostics, yet even the fastest technologies require hours, or days, to read a complete sequence. Now, a m.....»»

Drawing inspiration from natural sensory systems, an MIT-led team has designed a novel sensor that could detect the same molecules that naturally occurring cell receptors can identify......»»
Shrinking light: Waveguiding scheme enables highly confined subnanometer optical fields
Imagine shrinking light down to the size of a tiny water molecule, unlocking a world of quantum possibilities. This has been a long-held dream in the realms of light science and technology. Recent advancements have brought us closer to achieving this.....»»
Recent advances in vacuum ultraviolet photochemistry of astrochemically important small molecules
The photodissociation of an isolated molecule from a well-defined initial quantum state provides a lens through which one can investigate how and why chemical reactions occur, and provides numerous opportunities for fruitful, synergistic collaboratio.....»»
Scientists enrich nitric oxide-reducing microbes in bioreactor
Nitric oxide (NO) is a fascinating and versatile molecule, important for all living things as well as the environment. It is highly reactive and toxic, organisms use it as a signaling molecule, it depletes the ozone layer in our planet's atmosphere,.....»»
Scientists synthesize isotopic atropisomers based on carbon isotope discrimination
In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that ar.....»»
