Scientists have been working hard to improve targeted drug delivery by using the acidic environment in tumors. They focus on changing the active sites of drugs, like hydroxyl groups, to enhance stability, lower toxicity, and boost how well the drug hits its target. But the problem lies in making the
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
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
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
Deep in the microscopic world, a tiny organism named KARE_P3, 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
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
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
In 1903, American mountaineer Annie Smith Peck led an expedition to Bolivia's Mount Sorata (Illampu), aiming for the peak's 6, 367 meters (20, 892 feet). This journey is notable for being one of the first to employ supplemental oxygen on a great mountain. Instead of using heavy oxygen cylinders or r
Did you know that vaping can quickly affect your blood vessels and oxygen levels? Even if there’s no nicotine involved, the chemicals in e-cigarettes can still cause harm. A recent study found that vaping, with or without nicotine, can reduce blood flow velocity in the femoral artery. This artery is
You might think that making batteries is just about throwing some chemicals together. But scientists are getting really clever about it! They’re mixing carbon nanotubes and graphene to make special composites. These composites have nitrogen (N) and sulfur (S) added in just the right way to make zinc
