Green Tea Leaves Make Antibacterial Coatings

by Karin Heineman, Inside Science TV

The second most popular beverage in the world, after water, is believed to be tea.

There are different kinds of tea, but green tea carries with it a slew of promised health benefits. And now, scientists have made a new discovery within a simple cup of green tea.

Killer Eyes: Naturally Antibiotic Protein Stops Infections

by Marsha Lewis, Inside Science TV

They are known as the window to the soul, each a different color, size and shape. But could your eyes also fight infections?

For years optometrists have been trying to figure out why the human eye is resistant to infection.

“What we know is people virtually never get corneal infections unless they’re a contact lens wearer or unless they have very severe injury to the cornea,” said Suzanne Fleiszig, an optometrist at the University of California, Berkeley.

Poetic Justice: Filter Takes Machinery from Antibiotic-Resistant Bacteria to Remove Antibiotics From Water


by Michael Keller

The world is awash in antibiotics. We take them to fight off the bacteria that mean to colonize us. We feed them to animals to prevent the outbreak of disease in densely packed factory-farming operations. Even many of our cleaning and body care products, controversially, now contain them.

But many antibiotics don’t get fully metabolized within humans or animals and, through excretion, find their way into waste and surface waters. It’s a major environmental concern whose full ecological implications still aren’t clear.

And the problem creates a vicious cycle. Evolution gives our microbial adversaries the strategic advantage—the ability to adapt to our weapons and render them harmless. So we engage in a microscopic arms race, battering increasing numbers of antibiotic-resistant bugs with more and more drug compounds to keep them at bay.

So you could call it a small case of poetic justice when researchers figure out how to use the cellular machinery that renders some bacteria drug-resistant to reclaim antibiotics from contaminated water.
