Chemists use modified DNA nucleotides to create new materials
DNA evolved to store genetic information, but in principle this special, chain-like molecule can also be adapted to make new materials. Chemists at The Scripps Research Institute (TSRI) have now published an important demonstration ...

Researchers improve method to identify aquatic species using environmental DNA
Determining which fish are living in various bodies of water can be a daunting task for scientists studying those populations. Identifying invasive or endangered species, for example, has often relied on the ability to catch ...

Ultrasensitive DNA quantification by light scattering
Traces of biomolecules such as DNA can be detected with a new "dynamic" technique based on the observation of association and dissociation events of gold nanoparticles. If the desired DNA sequence is present, it can reversibly ...

Refined DNA tool tracks native and invasive fish
Rather than conduct an aquatic roll call with nets to know which fish reside in a particular body of water, scientists can now use DNA fragments suspended in water to catalog invasive or native species.

Simplified DNA barcoding technique enables food authentication with the naked eye
Is the food on the shelf really that what is written on the label? Its DNA would give it away, but the DNA barcoding technology, which can be used for this purpose, is labor-intensive. Now, in the journal Angewandte Chemie, ...

Sequencing method precise enough to reveal mechanisms by which bacteria resist antibiotics
A new technology can read the order (sequence) of the "letters" making up DNA code with enough accuracy to reveal how bacteria use high-speed evolution to defeat antibiotics. That is the finding of a study led by researchers ...
