Researchers have developed novel atomic force microscopy probes that can quickly and simultaneously measure biomolecule or material properties including adhesion, stiffness, elasticity and viscosity, in addition to the standard AFM topography scan.
New Technique Yields More Detailed Picture Of Chromatin Structure

Researchers have developed a new technique for imaging cells under an electron microscope that yields a sharper image of the structure of chromatin, the tightly wound bundle of genetic material and proteins that makes up the chromosomes.
Slowly-developing Primates Definitely Not Dim-witted

Some primates have evolved big brains because their extra brainpower helps them live and reproduce longer, an advantage that outweighs the demands of extra years of growth and development they spend reaching adulthood, anthropologists have concluded in a new study.
Road Kill Losses Add Up, Taxing Amphibians And Other Animals

When frogs hit the road, many croak. Researchers found more than 65 animal species killed along a short stretch of roads and nearly 95 percent of the total dead were frogs and other amphibians, suggesting that road-related death, or road-kill, possibly contributes to their worldwide decline.
Fishing Throws Targeted Species Off Balance, Study Shows

Fishing activities can provoke volatile fluctuations in the populations they target, but it's not often clear why. Fishing can alter the "age pyramid" by lopping off the few large, older fish that make up the top of the pyramid, leaving a broad base of faster-growing small younglings. Biologists found that this rapidly growing and transitory base is dynamically unstable -- a finding having profound implications for the ecosystem and the fishing industries built upon it.
New Model Predicts Where Corals Can Thrive

Scientists have developed a new model that accurately maps where coral reefs are in the most trouble, and identifies regions where reefs can be protected best. The model is being applied in areas throughout the Indian Ocean.

Quotes:
Habit is necessary; it is the habit of having habits, of turning a trail into a rut, that must be incessantly fought against if one is to remain alive.
Love is a canvas furnished by Nature and embroidered by imagination.
Photographers do this for a living, every single day -- they point their lenses toward every single corner of our world and somehow make the mundane mesmerizing through their artistic eye. It's all a matter of being aware of your surroundings and realizin
