Plants are very good at producing oxygen that we all need in order to breath, but what about clearing the air of harmful chemicals? Past research has revealed that plants do a bit of housekeeping when it comes to cleaning the air of certain compounds but researchers wondered if they could help boost that function with a genetic tweak.

In new research published in Environmental Science & Technology, researchers explain how they were able to give a common house plant more power to clean the air around it, and it’s all thanks to DNA from a mammal.

Ten people who mattered in science in 2018. Picks include a rogue gene-editor, a wunderkind physicist and a DNA detective who helped catch a serial killer.

Cervical cancer is the fourth most common cancer for women yet the leading cause of cancer-related death in developing countries, an unfortunate statistic that highlights the importance of access to screening. Through a comprehensive trial involving thousands of subjects, a newly designed test has been found to greatly outperform current screening methods in terms of both cost and accuracy, while also shedding new light on the mechanics at play.

For decades after the discovery of DNA, researchers mostly thought of genetics in terms of genes, the pieces or sequences of DNA that encode instructions for building proteins in cells. Then scientists discovered that genes make up just 2 percent of our DNA and that most genetic complexity stems from the vast non-gene code, which influences when genes are turned on or off. Further, half of that non-gene code was found to come from insertions of viral DNA. Consequently, say the authors, genetic variation, and the potential for disease-causing mistakes, occurs in transposons as well as in genes.

New laboratory techniques can identify which of our genes are influenced by DNA snippets that are left behind in our genetic code by viruses, a new study finds.
