The positions of these water molecules are often important for understanding protein flexibility and the ability of drug-like molecules to influence protein structure and function. In this study, different unique waters appeared at the surface of the protein under different experimental perturbations such as high temperature (red), high pressure (green), or default conditions (blue), offering … Read more

A soft summer evening in the Paleoproterozoic, as envisioned by DALL-E. Credit: DALL-E / Harrison Tasoff The sun has just set on a quiet mudflat in Australia’s Northern Territory; it’ll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning light. No leaves rustle … Read more

Toxic algae blooms on the water surface. Credit: FAU Harbor Branch Oceanographic Institute Florida’s 156-mile-long Indian River Lagoon (IRL) borders five different counties and has five inlets that connect the lagoon with the Atlantic Ocean. This estuary has recently experienced numerous phytoplankton bloom events due to increased seasonal temperatures and environmental impacts. Algal blooms produce … Read more

The research draws on survey results that were conducted following a public awareness campaign run … Read more

By adjusting the occupancy of the 4f orbitals, it is possible to induce the HAT mechanism for the activation of C-H bonds. Credit: Science China Press As the “holy grail” in the field of chemistry, the catalytic activation of methane has been a topic of great interest in the field of heterogeneous catalysis. Gas-phase experiments … Read more

Physicist Gregor Hlawacek, head of the EU project FIT4NANO, is responsible for a state-of-the-art facility at the HZDR where he can produce and analyze nanostructures using a particularly finely focused ion beam.

Credit: Pixabay/CC0 Public Domain For the first time, researchers have analyzed the impact of antibiotic use on the rise of treatment-resistant bacteria over the last 20 years in the UK and Norway. They show that while the increase in drug use has amplified the spread of superbugs, it is not the only driver. Researchers from … Read more

Credit: Frontiers of Environmental Science & Engineering (2023). DOI: 10.1007/s11783-024-1786-5 Free nitrous acid (FNA) is known for its capacity to inhibit various microorganisms in wastewater systems, significantly benefiting treatment process management. Initially deemed problematic due to its potential adverse effects on treatment, FNA is now employed to enhance wastewater management by mitigating odors, emissions, and … Read more
