Why did humans take over the world while our closest relatives, the Neanderthals, became extinct? It's possible we were just smarter, but there's surprisingly little evidence that's true.
In a typical cell, genes encoded in DNA are used to make messenger RNA (mRNA), which is used to make proteins, and this process of gene expression keeps the cell running. Gene expression is regulated in each cell such that ...
Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene—one ...
The Northern Hemisphere summer brought catastrophic fires and floods to many countries. Down south, the winter was the hottest ever recorded in Australia, fueled by record ocean temperatures.
Corina Godoy has an admittedly unorthodox dream.
Nearly every cell in our body contains pairs of each of our chromosomes, and these pairs are identical in all but one case: that of our sex chromosomes. Males typically have one X and one Y sex chromosome, while females typically ...
Most species are transitory. They go extinct, branch into new species or change over time due to random mutations and environmental shifts. A typical mammalian species can be expected to exist for a million years. Modern ...
DNA-based information is a new interdisciplinary field linking information technology and biotechnology. The field hopes to meet the enormous need for long-term data storage by using DNA as an information storage medium. ...
Commercially viable biofuel crops are vital to reducing greenhouse gas emissions, and a new tool developed by the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) should accelerate their development—as well ...
Researchers from Tokyo Metropolitan University have identified unifying features in the early evolution of X and Y chromosomes. Newly evolved sex chromosomes in three fruit fly species showed the same genetic compensation ...
