Not all zombies look like the walking dead, at least when it comes to plants. Normally, this Arabidopsis plant would sport a wealth of white flowers. But after being infected with bacteria, it makes only leaves and lives to do nothing but help its bacterial master.
Stripes may help keep pesky biting flies — which carry dangerous diseases — away from zebras, a new study concludes.
In dough, these yeast cells help bread rise. In the lab, scientists have found a way to make a new chromosome for the organism. It's a first step toward creating an entirely synthetic organism.
Scientists have discovered how some plant pathogens ensure their own survival by transforming flowering plants into strictly leaf-producing ones. These green ‘zombies’ attract insects that the parasites need to help them spread to other plants.
Synthetic biologists are scientists who create custom organisms in the lab. Their efforts have just taken a big step forward. They have created the first lab-made yeast chromosome. The advance could lead to entirely synthetic organisms customized to produce food, fuel or medicine.
A newly harvested plant, fruit or vegetable does not turn off — like a switch — and die, scientists report. Instead, an internal “clock” inside the fresh-picked plant continues to tick away. It responds to light and darkness, just as when it had been rooted in the soil.
Scientists have just pieced together evidence of a weird new dinosaur that sported sharp claws, feathers and a beak. And it just may have been one of the last dinos to roam Earth about 67 million years ago.
