Hidden rules of genetics for how life on Earth began

All living things use the genetic code to “translate” DNA-based genetic information into proteins, which are the main working molecules in cells. Precisely how the complex process of translation arose in the earliest stages of life on Earth more than four billion years ago has long been mysterious, but two theoretical biologists have now made a significant advance in resolving this mystery.

Food allergy is triggered by perfect storm of genetics and skin exposure to infant wipes, dust and food

Infant and childhood food allergy has now been linked to a mix of environmental and genetic factors that must coexist to trigger the allergy, reports a new study. Those factors include genetics that alter skin absorbency, use of infant cleansing wipes that leave soap on the skin, skin exposure to allergens in dust and skin exposure to food from those providing infant care. The good news is factors leading to food allergy can be modified in the home environment.

Environmental exposures more determinant of respiratory health than inherited genetics

Researchers have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry. The study analyzed more than 1.6 million data points from biological specimens, health questionnaires and environmental datasets, making this study one of the largest ever to examine the relationship between gene expression and environmental stimuli.

Landscape genetics branches out to help conserve riverside forests

Scientists have examined gene flow in the endangered maple, Acer miyabei, using landscape genetics, a powerful and increasingly popular tool in conservation projects. It involves the integration of population genetics and landscape ecology, in order to examine how recent landscape changes, for example, habitat fragmentation, have affected the genetic diversity of species.
