A Chink in Bacteria’s Armor

• Scientists untangle the structure of a recently discovered bacterial wall-building protein, found in nearly all bacteria • The discovery unveils potential weak spots in the protein’s molecular make-up • Findings can pave the way to next-generation broad-spectrum drugs that disrupt the protein’s function and disarm harmful bacteria

Berkeley Lab Scientists Print All-Liquid 3-D Structures

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to print 3-D structures composed entirely of liquids. Using a modified 3-D printer, they injected threads of water into silicone oil — sculpting tubes made of one liquid within another liquid.

It’s a Trap!

ItsATrap-molecules900x600.jpg

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have published a new study that identifies the process by which holes get trapped in nanoparticles made of zinc oxide, a material of potential interest for solar applications because it absorbs ultraviolet light.

The Clouds of Spaghetti That Keep DNA Data Safe

Cells can avoid “data breaches” when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert Einstein College of Medicine have shown. Their study appears in the March 23 issue of the Journal of Biological Chemistry.

Q&A: Bruce Gates on the Molecules That Can Drive Chemical Reactions

Bruce_Gates_portrait-5.jpg

There’s a class of materials responsible for the chemistry we rely on to make fertilizer for crops, create prescription drugs and refine oil into gasoline. They’re called catalysts, and they speed up chemical reactions and steer the direction of the changes that happen during the transformation from one chemical compound to another. Despite the fact that many catalysts are commonly found in biology (these catalysts are called enzymes), the chemistries of most catalysts are still not fully understood because of their complexity.
