In situ extraction and detection of DNA using nanopores

Being able to detect DNA from a single cell is important for the detection of diseases and genetic disorders. Measuring single DNA molecules has been possible for some time; however, directly detecting samples at the point ...

New insights into early embryonic development

The majority of pregnancies that fail do so at a very early developmental stage, before the pregnancy is even detectable by tests. This critical stage, occurring about a week after fertilization, is when an embryo implants ...

The holy grail of nanowire production

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter ...

Fish found to communicate with one another using urine

(Phys.org)—A trio of researchers with the University of Bern in Switzerland has found that at least one species of fish communicates with others of its kind using chemicals in its urine. In their paper published in the ...

Why did NASA scientists name a geologic feature on Mars "Aztec"?

Last week, NASA mission controllers for the Mars rover Curiosity spied a piece of rock outcropping with tiny holes, veins and fractures in the rocks. It's common practice for the science team to assign names to these targets ...
