Researchers at Oregon State University have for the first time traced the actions of a known carcinogen in cooked meat to its complex biological effects on microRNA and cancer stem cells.The findings are part of a growing awareness of the role of epigenetics in cancer, or the ways in which gene expression and cell behavior can be changed even though DNA sequence information is unaltered. The scien

When it comes to understanding climate change, it's all about the dirt. A new study by researchers at BYU, Duke and the USDA finds that soil plays an important role in controlling the planet's atmospheric future. The researchers set out to find how intact ecosystems are responding to increased levels of carbon dioxide in the atmosphere. Earth's current atmospheric carbon dioxide is 390 parts per m

During heavy rain, the lid of Nepenthes gracilis pitchers acts like a springboard, catapulting insects that seek shelter on its underside directly into the fluid-filled pitcher, new research has found. The findings were published June 13, in the journal PLoS ONE.Pitcher plants (Nepenthes) rely on insects as a source of nutrients, enabling them to colonise nutrient-poor habitats where other plants

From research labs all across the country and the world, there is growing evidence that blueberries could be powerful little disease fighters. Here is what we have learned so far… Antioxidants – Researchers at the USDA Human Nutrition Center (HNRCA) have found that blueberries rank #1 in antioxidant activity when compared to 40 other fresh fruits and vegetables. Antioxidants help neutralize harmful

THEY can "smell" chemicals and respond to light, but can plants hear sounds? It seems chilli seeds can sense neighbouring plants even if those neighbours are sealed in a box, suggesting plants have a hitherto-unrecognised sense. Plants are known to have many of the senses we do: they can sense changes in light level, "smell" chemicals in the air and "taste" them in the soil (New Scientist, 26 Sept
