Carbon Dots Emerge as a Powerful Weapon Against Superbugs and Biofilms
10+ hour, 38+ min ago (75+ words) A new comprehensive review published in the Journal of Nanoparticle Research surveys one of the most quietly promising corners of nanomedicine: carbon dots, nanoscale specks of carbon that are showing remarkable ability to kill bacteria and dismantle the sticky biofilms…...
Green Solvents and Microwaves Unlock Antioxidant Treasures Hidden in
15+ hour, 50+ min ago (55+ words) Chemists in Pakistan have shown that the secret to extracting powerful antioxidant compounds from the leaves of the lemon-scented eucalyptus tree lies in matching the polarity of the solvent to the chemistry of the target molecules. In a study published…...
Freshwater shrimp kept for twenty hours at a caffeine concentration detected in highly polluted rivers spent less time in the dark than shrimp kept at ordinary background levels, and that shift was about the same size as the one caused by a parasite that manipulates them into being eaten by water birds
1+ day, 13+ hour ago (524+ words) The high tanks held 10,000 nanograms of caffeine per litre and the low tanks held 100, two levels chosen because both occur in real rivers. There was no caffeine-free group at all, so what the experiment measures is the distance between those…...

4+ day, 6+ hour ago (50+ words) Our Science and Technology Earth and Atmospheric Science HPC, Simulation and Data Science Lasers & Optical Science and Technology Nuclear, Chemical & Isotopic Science and Technology Learn How We Make Science and Technology Happen Learn More About Our Science and Technology Applying…...
Molecular Architecture Control Yields Strong and Flexible Degradable Food Packaging Materials
3+ day, 8+ hour ago (456+ words) Virginia Tech researchers have put that idea to the test, creating degradable polymers with a new molecular architecture that combines properties that are often difficult to achieve in one material: strength, toughness, flexibility, and the ability to block oxygen. The…...
Is Life Itself a State of Matter?
3+ day, 9+ hour ago (764+ words) Consider self-assembly, a common phenomenon within both the physical and biological worlds. Physical stuff routinely assembles into lifeless forms, such as crystals or amorphous rocks. But in unique circumstances, it can also self-assemble into living forms, such as bacteria, birds,…...
DNA Mystery Unraveled as Strands Zip Together
4+ day, 8+ hour ago (228+ words) Researchers have captured the moment two DNA molecules zip together, overcoming their identical negative charges to pair up, solving a mechanism that has puzzled scientists for more than 20 years. Using high-powered atomic force microscopy, scientists at the University of Sheffield…...
A protein that makes jellyfish glow was repurposed by researchers in Sweden as the light-harvesting material in a tiny solar cell — when exposed to UV light, it generated an electrical current
4+ day, 8+ hour ago (27+ words) Shine ultraviolet light on a droplet of glowing jellyfish protein and, for a moment, it stops behaving like biology and starts behaving like a solar cell. An...
Better active ingredients thanks to tiny rings
4+ day, 15+ hour ago (796+ words) The authors of the study Konstantin Günther, Nuno Maulide, and Gwyndaf Oliver (f.l.t.r.) Connect these carbon triangles to an amine, a functional group with a nitrogen at its center, and you get aminocyclopropanes. They are of particular interest…...
PhD student Anjana Adhikari turns environmental research into public health action
4+ day, 23+ hour ago (783+ words) For Anjana Adhikari, pursuing a PhD in Environmental Health Sciences at the University of Wisconsin–Milwaukee has meant taking science beyond the laboratory — into Great Lakes waters, communities affected by harmful algal blooms and research sites around the world. Adhikari…...
