The sticky science of underwater adhesives

Mussels stick to rocks on the seafloor, to aquatic plants, and—to the consternation of boaters—they can hitch rides fastened to seafaring vessels no matter their composition: metals, rubber, glass, wood and more.

New method to create ultrafast 3-D images of nanostructures

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. ...

To protect stem cells, plants have diverse genetic backup plans

Despite evolution driving a wide variety of differences, many plants function the same way. Now a new study has revealed the different genetic strategies various flowering plant species use to achieve the same status quo.

Novel approach promises ready access to hard-to-study proteins

DNA and the genome, we know, provide the blueprint for life. But it is the proteins made according to the genome's instructions that are the nuts and bolts of living organisms, providing the molecular building blocks for ...

Turning silenced cancer genes back into fighters

Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the ...

Can we cure cancer by finding out how two proteins interact?

In a paper published in the Journal of Biological Chemistry, Dr. Özdemir has studied two protein families named Rho GTPases and IQGAPs, which are known to play an important role in cancer metastasis. These two "suspicious" ...

The arrestin-GPCR connection

G-protein coupled receptors (GPCRs) are the "inbox" of environmental messages in mammalian cells. Because of their central role in signaling pathways, mutations resulting in abnormal GPCR functions cause a wide variety of ...
