Scientists have found a better way to spot harmful chemicals in the body. These chemicals come from diesel exhaust. They are called amino-polycyclic aromatic hydrocarbons, or amino-PAHs for short. These are bits left behind in the body after it breaks down other harmful chemicals called nitro-PAHs.
In the late afternoon of a Saturday, around 12:15, a tornado swept through Tangipahoa Parish. It began its destructive path east of Kentwood. The National Weather Service has confirmed the tornado's presence. This is not the end of the story, though. The twister did not stop at the parish line.
First, let's dive into the world of a unique molecule: 6-oxo-5-sulfanyl-1H-pyridine-3-carboxylic acid. Scientists used a method called DFT to explore how this molecule behaves in different environments, like gas and various solvents. This method helps us understand the molecule's structure and how i
Ever wondered how viruses like Nipah manage to invade our cells? It all comes down to their proteins, particularly the fusion protein, NiV-F. This protein is crucial for the virus to fuse with our cell membranes, allowing it to enter and replicate. Nipah virus, like other paramyxoviruses, uses two
You might think of petroleum as just something that fuels our cars. But in the Khuzestan province of Iran, it's also used to fight off the desert. Farmers cover their soil with petroleum to stop wind erosion, a process called mulching. This study found that while this method works, it also comes wit
Pulmonary arterial hypertension (PAH) is a serious condition that makes it hard for the heart and lungs to work together. Patients often feel tired and have a low survival rate. While current treatments can improve their quality of life, the long-term effects aren't great. In a recent study, resear
Hypoxia-induced pulmonary artery hypertension (HPH) is a problem that arises from chronic lung diseases where the body doesn't get enough oxygen. It's the third most common type of pulmonary artery hypertension (PAH). Scientists have found that epigenetic factors, which are processes that affect how
Have you ever thought about what's in the smoke you see during a wildfire? Besides being scary and bad for the environment, it also contains chemicals called polycyclic aromatic hydrocarbons (PAHs). These are created when things like wood burn. Usually, we encounter tiny amounts from car fumes and i
