Do nanomaterials affect pollinating insects?

There is concern that pollinating insects are at risk due to nanomaterial exposure. Pollinating insects like bees or bumblebees are potentially exposed to nanomaterials via aerosols, the pollen of contaminated plants and water droplets. Managed pollinators may be additionally exposed in the hives due to direct application of nanomaterials by beekeepers.

Engineering cellular function without living cells

Scientists have come up with a systematic method for studying and even predicting gene expression - without using cells. Using their innovative, quantitative approach, they measured important parameters governing gene regulation. This allowed them to design and construct a synthetic biological logic gate, which could one day be used to introduce new functions into cells.
