obligatory for pregnancy, whether in males or females. Aftermating, the fertilised eggs differentiate into embryos, which attach to the inner surface of the pouch walls. While these embryos largely rely on their yolk sacs for nourishment, it is becoming...

How to Fail Well
the student found it matched a sequence found within the human histone acetyltransferase (HAT), an enzyme complex that attaches acetyl groups to proteins to control gene expression. He decided to test the hypothesis that the bacterial protein had a...

Breaking down barriers
about exactly what triggers their formation and how to prevent them forming in the first place. Most microorganisms can attach to and grow upon surfaces (1). After attachment (2), the production of extracellular polymers helps solidify the attachment...

Hunting for 'holes of hope'
mixed with a culture of the target pathogen and incubated overnight at 37 °C. Any suitable phages found in the sample will attach to their host and kill it, producing more phages. Again, the bacteria is removed and the now enriched phage mixture is...

How to...explore rock pools
seaweeds are the base of coastal food chains and provide not only food but a home for many animals, as well as an attachment point for other algae where bare rock is at a premium. Grouped arbitrarily into greens, browns and red seaweeds, depending on...

Built to last
artemisiifolia (ragweed) pollen surfaces possess hooks and Helianthus annuus (sunflower) pollen grains are highly spiked to attach to insects (and subsequently a plant’s stigmatic surface). In contrast, wind-pollinated plants such as grasses produce...
