DNA barcoding is now being used to identify the plant matter in human feces, revealing what a person has eaten. A reliable genetic marker for plant-based foods can be retrieved from poop, showing not ...

James Chappell, associate professor of biosciences and bioengineering at Rice University. In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, ...

Being able to distinguish between different types of scuttle flies (Phoridae) requires expertise that very few people possess. But DNA analysis is of great help. The Earth is an almost unimaginably ...

Using DNA barcodes to track cancer cells through time, scientists have shown that cells within a cancer have diverse abilities to escape immune system defenses. Some cancer cells can deploy parallel ...

The Earth is an almost unimaginably diverse planet in terms of species. Researchers have identified between two and three million species, but there are many more that we know nothing about. The ...

Discover why zoology is referred to as the 'Scribe of Species.' Discover the various job pathways available to zoologists in ...

Nucleic acid-based therapeutics, including antisense oligonucleotides (ASO), small interfering RNA (siRNA), messenger RNA (mRNA), immunomodulatory DNA/RNA, and gene-editing guide RNA (gRNA), hold ...

Advances in sequencing technologies have accelerated the discovery of the genetic causation of diseases and new cell types. This revolution has also given rise to a new technique known as genetic ...
