Latest Recession Strategy: Grow Your Own Vegetables

Last year, record numbers of Americans experimented with growing vegetables to offset rising food prices. So not surprisingly, "vegetable gardening is expected to surge again in 2009 as many Americans opt to grow their own produce to save money during the recession," according to a recent news release as well as the Baltimore Sun.


Garden purveyor W. Atlee Burpee & Co has confirmed through a cost-analysis study that growing your own produce really does save money — a 1 to 25 cost-savings ratio for those who grow their own as opposed to purchasing them at the supermarket! That means, if you invest $50 in your vegetable garden—on seeds and fertilizer—you will be able to harvest at least $1,250 worth of vegetables." And that's not mention the health benefits.

  • The field of plant neurobiology studies the complex behavior of plants.
  • Plants were found to have 15-20 senses, including many like humans.
  • Some argue that plants may have awareness and intelligence, while detractors persist.

  • A new study used an MRI machine to examine how vaping e-cigarettes affects users' cardiovascular systems immediately after inhalation.
  • The results showed that vaping causes impaired circulation, stiffer arteries and less oxygen in their blood.
  • The new study adds to a growing body of research showing that e-cigarettes – while likely safer than traditional cigarettes – are far from harmless.

Space is dead: A challenge to the standard model of quantum mechanics

Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.

  • Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
  • In nature, properties of Particle B may be depend on what we choose to measure or manipulate with Particle A, even at great distances.
  • In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
