Genetics denote feral cat source
Feral cats arrived on Dirk Hartog Island in two separate waves, but are now reproductively isolated, according to genetic analysis.
Where no lab has gone before: Single-Molecule Electrokinetic Traps
Rare byproduct of marine bacteria kills cancer cells by snipping their DNA
(Phys.org) —Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
The final nail in the Jurassic Park coffin: Next generation sequencing reveals absence of DNA in sub-fossilized insects
It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the ...
DNA catalysts do the work of protein enzymes
(Phys.org) —Illinois chemists have used DNA to do a protein's job, creating opportunities for DNA to find work in more areas of biology, chemistry and medicine than ever before.
Researchers develop new sensor for methylated DNA
Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation—the addition of a methyl group of molecules to a DNA strand—is ...
Everything flows in rapid diagnostic tests
(Phys.org) -- Our ability to detect pathogens has become quite good, but it usually requires complex laboratory techniques. Sometimes we need a quick result, or there is no laboratory nearby. Portable and ...
New method for sequencing genome in a single cell
NEC plans DNA analyzer for nearly-instant results
Scientists tease DNA from eggshell of extinct birds
(PhysOrg.com) -- In a world first, scientists in Australia announced on Wednesday they had extracted DNA from the fossilised eggshells of extinct birds, including iconic giants such as the moa and elephant ...
Excessive alcohol consumption may lead to increased cancer risk
Researchers have detected a link between alcohol consumption, cancer and aging that starts at the cellular level with telomere shortening.
A roundabout route to protein production
Proteins are typically encoded by linear strands of messenger RNA (mRNA). These mRNA molecules are translated into polypeptide chains by ribosomes, with each ribosomal read-through of the mRNA generating ...
New DNA test identifies ingredients in foods
Scientists at Mainz University develop a novel screening procedure for accurately determining the amount of animal, plant, and microbial substances in foods
Improving DNA amplification from problematic plants
The polymerase chain reaction (PCR) is a common technique used to amplify, or copy, pieces of DNA. Amplified DNA is then used in genetic analyses for everything from medicine to forensics. In plant research, PCR is a vital ...
