Small Helpers, Big Impact: Making Ammonia from Nitrate

January 29, 2025

Imagine tiny, tiny particles, smaller than a speck of dust, doing a big job! Scientists have found that these tiny Co nanoparticles, covered in a special shell, can turn nitrate into ammonia. This shell is made of N-doped carbon and Co hydroxide, which helps the particles spread out evenly and expos

Lebanon's Post-War Cleanup: A Daunting Task

January 28, 2025

Ahmad Mehdi, 20, has been living in a partially destroyed home since October. An Israeli airstrike in his Beirut neighborhood flattened the building next door, reducing it to a pile of rocks, dirt, and steel. His own home, on the fifth floor, lost its kitchen and living room. He and his family are e

Fatty Acids in Dolphins and Porpoises: A Warning Signal

January 28, 2025

In the busy waters of the northern South China Sea, scientists have been studying something unusual happening to dolphins and porpoises. They found high levels of something called organohalogen contaminants (OHCs) in these marine mammals. These OHCs can mess with the body's fatty acid (FAs) levels,

The Trouble with Eco-Friendly Plastics: How PLA Affects Male Mice Fertility

January 28, 2025

You might think polylactic acid (PLA) is a safe bet for the environment. After all, it's biodegradable and often touted as an "eco-friendly" alternative to traditional plastics. But hold on! Recent studies have found that PLA microplastics (PLA-MPs) could be causing trouble for male mice. Imagine i

Nano Films for On-Chip Energy Storage

January 27, 2025

Did you know that tiny molecular layers can be grown and used as teeny-tiny energy storage devices on a chip? Scientists have found a way to create these using benzimidazole compounds. They laid these layers on a special surface withelectrochemical methods, creating films as thin as 10 nanometers. I

“Formulating Farnesol with Cyclodextrins: A Safer Approach for Combat Antibacteria”

January 27, 2025

Imagine farnesol, a sticky compound that loves water about as much as a cat loves baths. Scientists figured out how to mix it with other molecules (like β-cyclodextrin and hydroxypropyl-β-cyclodextrin) to make it more friendly with water. They chose a cool method called freeze-drying to make these m

Boosting Cancer Therapy with Bacteria and Metal

January 27, 2025

Radiotherapy, a common cancer treatment, often struggles to effectively kill tumor cells. Researchers have discovered a unique way to enhance this therapy using a clever combination of bacteria and a metal called selenium. They've created tiny particles, called BL@SeNPs, which are made by coating th
