How Sericin and Hydroxychloroquine Team Up to Fight Lung Cancer in Mice

December 14, 2024

There's an interesting team-up happening in the world of science. Researchers found that sericin and hydroxychloroquine (HQ) can work together to reduce lung damage and even prevent early stages of lung cancer in mice. This duo targets a specific pathway in the body called PI3K/Akt/Nrf2/NF-κB. By ta

Revamping Pb(II) Catalysts for Green Energy Production

December 12, 2024

Did you know that researchers are cooking up new ways to make clean energy? Instead of relying on traditional methods, they’re now exploring how to use lead compounds, specifically Pb(II) carboxylate catalysts, to generate both oxygen and hydrogen. This is a big deal because these gases are crucial

Progressive Prosecutors: What Went Wrong?

December 12, 2024

You might have heard that some cities have been seeing more crime lately. Some people blame progressive prosecutors for this. These prosecutors often don't require cash bail, lower charges, and give shorter sentences. They also might not prosecute two out of three people arrested. But some people sa

Unveiling Hidden Power: Antibiotics from Microbes

December 12, 2024

Deep in the microscopic world, a tiny organism named KAREP3, a gram-positive microbe, has been discovered to hold a big secret. This microbe, found living inside plants, can break down tough epoxy resin materials. When scientists studied it, they found that it produces special molecules called seco

The Power of Biomaterials in Neural Regeneration

December 2, 2024

Did you know that our bodies produce tiny molecules called reactive oxygen species (ROS) during normal oxygen metabolism? These molecules can act as messengers, influencing various processes in the body. However, when there are too many ROS, they can cause big problems, especially in the brain and n

Speeding Up Hydrogen Power: The Titanium Touch

December 1, 2024

You know how hydrogen power needs a quick oxygen reaction? That's where the oxygen evolution reaction (OER) comes in, and it's usually not fast enough. Scientists have come up with a clever trick: they mixed titanium into ruthenium oxide (RuO2). This combination creates "bridged oxygen" sites that a
