Plants can see, smell, feel and remember but can they think?


Are plants aware?

Are plants aware?  In the new book, ‘What a Plant Knows,” Daniel Chamovitz argues that a plant can see, smell and feel.  It can mount a defense when under siege, and warn its neighbors of trouble on the way. A plant can even be said to have a memory. But does this mean that plants think — or that one can speak of a “neuroscience” of the flower? Chamovitz answered questions from Mind Matters editor Gareth Cook.

How molecules move energy after light absorption

Molecule 111222152010-large

MSU chemist Jim McCusker and postdoctoral researcher Dong Guo proved an 84-year-old theory.

The same principle that causes figure skaters to spin faster as they draw their arms into their bodies has now been used by Michigan State University researchers to understand how molecules move energy around following the absorption of light.

Conservation of angular momentum is a fundamental property of nature, one that astronomers use to detect the presence of satellites circling distant planets. In 1927, it was proposed that this principle should apply to chemical reactions, but a clear demonstration has never been achieved…

DNA could be the next frontier for hackers and biological warfare


Synthetic biology will lead to new forms of bioterrorism.

Computer-designed viruses that cure disease, new bacteria capable of synthesizing an unlimited fuel supply, new organisms that wipe out entire populations and bio-toxins that target world leaders may sound like devices restricted to feature-film script writers, but it is possible to create all of these today, using the latest advances in synthetic biology.

City dwellers suffer more stress and anxiety than their rural counterparts


Different parts of the brain are used depending on where you live.

People born and bred in cities were more likely to suffer anxiety or mood disorders than their rural counterparts.  People living in the countryside are less likely to suffer stress and anxiety than city dwellers because their brains are wired differently, a study has found.
