Homework Help: Science for Kids Science is the study of the world around us. Scientists learn about their subject by observing, describing, and experimenting. There are many subjects and branches of science. Some study outer space like astronomy. Other sciences study life (biology) or the earth (geology) or even matter and energy (physics). Much of the science we know today was discovered using the Scientific Method. Be sure to check out our new dedicated sections on biology, chemistry, physics, and Earth science.

The Science Spot ScienceGeek.net Homepage A Plant Cells comparison to a Factory by Karan Mann on Prezi Bioluminescence in the Gippsland Lakes | Phil Hart These pictures of bioluminescence in the Gippsland Lakes in my gallery have proven quite popular, so it seems time to provide a story to accompany them. But this is not a short story, rather a convoluted one of fires and floods, of microscopic algae and the inspiring, remarkable and surprising beauty of nature. The story begins with alpine bushfires in Victoria, which started on 1st December 2006 when over 70 fires were started by a band of thunderstorms and lightning strikes which moved across the state.

In the end, it was not any ordinary rainfall event that arrived that winter.

The Secret Language of Plants Up in the northern Sierra Nevada, the ecologist Richard Karban is trying to learn an alien language. The sagebrush plants that dot these slopes speak to one another, using words no human knows. Karban, who teaches at the University of California, Davis, is listening in, and he’s beginning to understand what they say. The evidence for plant communication is only a few decades old, but in that short time it has leapfrogged from electrifying discovery to decisive debunking to resurrection. Richard Karban Richard Karban, an ecologist at the University of California, Davis, studies how sagebrush communicate. The first few “talking tree” papers quickly were shot down as statistically flawed or too artificial, irrelevant to the real-world war between plants and bugs. Plant communication may still be a tiny field, but the people who study it are no longer seen as a lunatic fringe. Scientists are also exploring how the messages from these signals might spread.

Move over elephants: Mimosas have memories too Not long after publishing a paper in a prestigious journal about plants being able to 'talk' using sound, Monica Gagliano is back with her new findings showing that they can 'learn'. While this may sound stranger than fiction, Dr Gagliano, an Australian Research Council research fellow at The University of Western Australia's Centre for Evolutionary Biology, has solid evidence to support her theories, the latest of which is published in Oecologia. Her work is becoming famous, with a recent mention by Michael Pollan in the New Yorker. Her new article - written with Associate Professor Michael Renton and Dr Martial Depczynski from UWA's School of Plant Biology and Oceans Institute respectively, and Professor Stefano Mancuso at the University of Florence in Italy - is titled "Experience teaches plants to learn faster and forget slower in environments where it matters".
