A Nobel prize for understanding how genes are turned on and offThe early-morning call from Sweden came on Monday to American molecular biologist Gary Ruvkun for his work in discovering microRNAs, which are essential for regulating genetic activity in plants and animals. Ruvkun says that research based on this work helps us understand basic biology, but has also provided significant insight into disease and might even help us understand whether there is life on other planets. Biologists discover a new microbial world in your bathroomResearchers have found a new biodiversity hotspot. Environmental microbiologist Erica Hartmann and her team sampled showerheads and toothbrushes in ordinary bathrooms, and found a host of bacteria and hundreds of previously unknown viruses. But don’t panic: much of this new life are bacteriophages — viruses that infect bacteria — which are harmless to humans and could be potential weapons against the bacteria that can cause human disease. The study was published in the journal
