Phys.org / Nanoparticles sneak antibodies into cells to inhibit cancer and inflammation
A delivery system that uses lipid nanoparticles to sneak proteins into cells can accomplish the same feat by smuggling therapeutic antibodies, new research has found.
Phys.org / Self-driving chemistry lab discovers catalysts that can switch products on demand
Researchers have developed a self-driving chemistry lab that can autonomously search through hundreds of catalyst recipes and reaction conditions to identify faster, more selective and more programmable ways to make important ...
Phys.org / New energy-boosting quantum mechanism discovered in photosynthetic bacteria
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 ...
Phys.org / Hidden dark force may slow cosmic structure growth, not speed it up
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
Phys.org / Espresso 'pucks' stop behaving predictably above certain pressures
When a physics student asked baristas at the Warsaw Coffee Conference what their biggest question for scientists was, the baristas said they wanted to know how to stop channeling during brewing.
Phys.org / Discovery of how cells maintain their DNA could shield key healthy cells from chemotherapy side effects
A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. ...
Phys.org / How continental shelf seiches triggered flooding following New York and New Jersey hurricanes
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 ...
Phys.org / Looking at AI startups to predict which jobs AI will affect
A study of funded AI startups provides a glimpse of which jobs may be most affected by AI. As AI tools are embraced by industry after industry, the impacts of these tools on jobs remain unclear. Previous analyses have focused ...
Phys.org / Controlling ice crystal growth using polymer nanoparticles
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 ...
Phys.org / Drug peptides defy shape rules, activating receptors without full spiral form
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 ...
Phys.org / Unique instruments automate sample preparation, quality control for cryo-electron microscopy
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 ...
Phys.org / Next-generation pesticide disrupts bumblebee reproduction
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.
