An obscure swatch of human DNA once thought to be nothing more than biological trash may actually offer a treasure trove of insight into complex genetic-related diseases such as cancer and diabetes, thanks to a novel sequencing technique developed by biologists at Texas A&M University. The game-changing discovery was part of a study led by Texas A&M biology doctoral candidate…
A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making “epigenetics” a hot topic. Epigenetic modifications do not affect the DNA sequence of genes, but change how the DNA is packaged and how genes are expressed. Now, a study by scientists at UC Santa Cruz shows…
War—what is it good for? “Absolutely nothing” according to the refrain of a 1970 hit song. Many humans would agree with this sentiment. But a major new study of warfare in chimpanzees finds that lethal aggression can be evolutionarily beneficial in that species, rewarding the winners with food, mates, and the opportunity to pass along their genes. The findings run…
The age of the Anthropocene–the scientific name given to our current geologic age–is dominated by human impacts on our environment. A warming climate. Increased resistance of pathogens and pests. A swelling population. Coping with these modern global challenges requires application of what one might call a more-ancient principle: evolution. That’s the recommendation of a diverse group of researchers, in a…
By comparing the genomes of malaria parasites that affect chimpanzees and those that affect humans, researchers discovered that it is the difference in the parasites’ surface proteins that determine which host it will infect. Out of a genome of approximately 5,500 genes, researchers found that most genes have directly equivalent counterparts between the human and primate parasites. However, portions of…
