When many of us think about how drugs work in the body, we may first think about how a drug gets into the body, such as a pill versus an injection. In the Gellman Group at the UW–Madison Department of Chemistry, researchers ...

Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 Nobel Prize in chemistry ...

Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led ...

Ice formation can damage biological samples, tissues and materials during freezing and thawing. In nature, specialized molecules known as ice-binding proteins prevent ice crystals from growing too large, helping organisms ...

Researchers from the Biosciences Department at Durham University have discovered a previously unknown mechanism that helps plants control the formation of wood, a finding that could open new directions for research into plant ...

In 1938 and 1944, two major hurricanes struck Long Island, and after the initial winds subsided, the surges came back unexpectedly hours later, leading observers to wonder whether this was a tsunami. In a study appearing ...

A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection. B cells can produce different classes of antibodies tailored for specific infections through controlled ...

When and where the next large earthquake will strike remains one of the most difficult questions in geoscience. Researchers from the GFZ Helmholtz Center for Geosciences led by Dr. Sadegh Karimpouli and Prof. Dr. Patricia ...

Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the performance of quantum computers and demonstrated ways to overcome their impact.

How does your body produce millions of antibodies from one genome? New research reveals how two closely related proteins help immune cells fold DNA, connecting distant genetic pieces to create diverse antibodies that help ...

Bumblebees are only an inch long, but they help power the global food system. Roughly one-third of the food we grow depends on pollinators like bees—and those bees are regularly decimated by pesticides.

At first glance, bat sea stars, the nubbly, orange, many-footed creatures often found on the seafloor, seem about as far from humans as one can get. Appearances can be deceiving, however. Scientists have found evidence showing ...
