Artificial cells are tiny bacteria fighters

"Lego block" artificial cells that can kill bacteria have been created by researchers at the University of California, Davis Department of Biomedical Engineering. The work is reported Aug. 29 in the journal ACS Applied Materials ...

'Blink' and you won't miss amyloids

Tiny protein structures called amyloids are key to understanding certain devastating age-related diseases. Aggregates, or sticky clumped-up amyloids, form plaques in the brain, and are the main culprits in the progression ...

Measuring the tension of a cell with a molecule

The volume of cells can vary dramatically. Similarly to an inflating balloon, the volume increase of growing cells pushes on the plasma membrane—the lipid envelope that surrounds the cell. This "turgor" pressure increases ...

Carbohydrate capture

LMU chemists have designed and synthesized a helical molecule that specifically recognizes and binds to a disaccharide consisting of two five-carbon sugar units.

Gut bacteria provide key to making universal blood

In January, raging storms caused medical emergencies along the U.S. East Coast, prompting the Red Cross to issue an urgent call for blood donations. The nation's blood supply was especially in need of O-type blood that can ...

Maple leaf extract could nip skin wrinkles in the bud

Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep—and that's a good thing. Today, scientists report that an extract from the leaves ...
