A New Era of Debris Flow Experiments in the Oregon Woods

Studying the physics of landslide initiation and the dynamics of debris flows is challenging, as these phenomena occur spontaneously, commonly in remote locations, and usually during inclement weather. Those who do this work trudge into the muck not only because the unpredictable natures of natural slope failures and landslide runouts are scientifically interesting […]

Experiments with bifluoride ions show evidence of hybrid bonds

Hydrogen bonds. (A) Types of hydrogen bonds depending on donor-acceptor distance. Potentials of proton motion are shown along with the first three quantum levels and the associated lowest-energy transitions. (B) Principal coordinates of any H-bond demonstrated with HF2−(aq): donor-acceptor distance (dFF), proton asymmetry (Δ), and linearity (δ). Credit: Science (2021). DOI: 10.1126/science.abe1951 A team of […]

In lab experiments, pralatrexate outperforms remdesivir against SARS-CoV-2 — ScienceDaily

A novel computational drug screening strategy combined with lab experiments suggest that pralatrexate, a chemotherapy medication originally developed to treat lymphoma, could potentially be repurposed to treat Covid-19. Haiping Zhang of the Shenzhen Institutes of Advanced Technology in Shenzhen, China, and colleagues present these findings in the open-access journal PLOS Computational Biology. With the Covid-19 […]

In rodent experiments modeled to mimic real-life circumstances, scientists revealed brain mechanisms that could lead to targeted treatments. — ScienceDaily

Through intricate experiments designed to account for sex-specific differences, scientists at Scripps Research have collaborated to zero in on certain changes in the brain that may be responsible for driving alcohol abuse among people with post-traumatic stress disorder, or PTSD. In studies with rodents, researchers found that males and females exhibit their own distinct symptoms […]
