Japanese plants produce compounds that exhibit potent anti-HIV activity
Structure of previously undescribed daphnene diterpenoids isolated from D. pseudomezereum.. Credit: Dr. Wei Li Researchers have discovered that Daphne Pseudomezereum (commonly known as Onishibari) contains substances that inhibit human immunodeficiency virus (HIV) replication. The plants were grown in the Medicinal Plant Gardens of the Faculty of Pharmaceutical Sciences at Tohhon University. This finding is expected to lead to the discovery…

Detroit’s reparations task force must produce a report by 2025, but moving through this difficult task slowly may help
The Conversation by Camry Hudgins, Erica Noelle Benson, Mara Ostfeld, and Vincent Hutchings Credit: Pixabay/CC0 Public Domain The task of formulating reparations at the local government level is intense. People in Detroit know. In November 2021, residents voted to create a reparations commission to make recommendations on housing and economic development programs to address historical discrimination against Black residents. Three…

Climate, migration and conflict combine to produce ‘deadly’ severe tropical cyclones like Chido
Credit: Pixabay/CC0 Public Domain Cyclone Chido was a “strong tropical cyclone” equivalent to a Category 4 hurricane in the Atlantic Ocean. It made landfall on Mayotte, a small island northwest of Madagascar, on December 14, producing wind gusts close to 155 mph (250 kph). It then struck Mozambique in East Africa with the same ferocity. The storm bypassed north of…

Eco-friendly reactor mimics lightning to produce ammonia from air and water
A plasma electrochemical reactor developed by Chris Li’s team can convert nitrogen in the air into ammonia without producing carbon dioxide emissions. Credit: Douglas Levere/University at Buffalo There’s a good chance you owe your existence to the Haber-Bosch process. This industrial chemical reaction between hydrogen and nitrogen produces ammonia, a key ingredient in the synthetic fertilizers that provide much of…

Researchers use multiphase composition and electrospinning to produce SiOC nanofibers
The introduction of Co and Ti significantly promoted the nanostructuring of the fibers and improved the dielectric loss of the fiber films. With a fiber loading of only 5 wt%, CTS-800 offers strong absorption (minimum return loss, RLmin: -66.0 dB), thin thickness (2.5 mm), and excellent effective absorption bandwidth (EAB) It exhibits excellent microwave absorption properties such as. :8.64GHz). Furthermore,…
