Mining the botulinum genome

(Norwich BioScience Institutes) Scientists at the Institute of Food Research have been mining the genome of C. botulinum to uncover new information about the toxin genes that produce the potent toxin behind botulism.

Bioinformatician presents the first map of the microverse

What defines the habitat—the ecological niche—of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is ...

Parasitic plants use stolen genes to make them better parasites

Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host's nutrients. A new study led by researchers at Penn State and Virginia Tech reveals that ...

Fungus senses gravity using gene borrowed from bacteria

The pin mold fungus Phycomyces blakesleeanus forms a dense forest of vertically growing fruiting bodies, but how does it know which way is "up"? New research publishing 24 April in the open access journal PLOS Biology, from ...

Researchers engineer bacteria that can detect tumor DNA

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of ...

Exploring the existence of life at 50°C

There are an estimated 8.7 million eukaryotic species on the planet. These are organisms whose cells contain a nucleus and other membrane-bound organelles. Although eukaryotes include the familiar animals and plants, these ...

Determining the timing of methanogen evolution

Early forms of life very likely had metabolisms that transformed the primordial Earth, such as initiating the carbon cycle and producing most of the planet's oxygen through photosynthesis. About 3.5 billion years ago, the ...
