White-tailed jack rabbits living in the Greater Yellowstone Ecosystem have apparently hopped their way into oblivion, according to a new study by the Bronx Zoo-based Wildlife Conservation Society.
Q: I know it seems too soon to think about summer plants; however, I want to get an early start and buy some smaller plants now so they will grow bigger before summer. My problem is that my patio and garden receive plenty of sunshine, meaning it gets really hot. The trees are too small and I don't have a trellis for shade.
Last winter, the Jackson & Perkins rose company asked if I would like to grow roses during the summer of 2007; they would be released to the public in 2008. I jumped at the chance. I like roses and couldn't pass up free plants. If J&P was going to release them next year, I knew they had already done the research — I expected these to be good roses.
The eyes may be windows to the soul, but they provide a pretty good scientific view of the brain, too. Neurobiologist Christof Koch of the California Institute of Technology and colleagues report that the pupil — the circular opening at the center of the eye that contracts or dilates to regulate how much light enters — changes to correspond to the moment when the brain makes a simple decision.
As many longtime readers know, I like to test garden products before recommending them to you; I don't believe press releases any more than you do. Just before Christmas I discovered a product that could have been a good present, but I didn't have time to test it. Now I have used it long enough to let you know it will work as the advertising says it does.
Being fairly nomadic and almost constantly on the move for new forage, African elephants (Loxodontia africana) don't really keep house. But don't tell that to the Kenya dwarf gecko (Lygodactylus keniensis), which probably thinks the big, gray, lumbering pachyderms are wonderful homemakers.
Mother Nature regulates critical cellular activities in plants and animals by using enzymes, catalysts that bring about specific biochemical reactions. Looking to learn from nature, a team of Northwestern University chemists has received a $5 million grant from the Air Force Office of Scientific Research to study and develop bio-inspired supramolecular enzyme mimics for military and civilian applications.
In the aftermath of the Southern California wildfires in October this year that killed seven and destroyed over 2,000 homes, Governor Arnold Schwarzenegger instructed his Blue Ribbon Task Force to review their findings on the 2003 wildfires, which burned 3,600 homes in many of the same places.
Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.
