Scientists have found a treasure trove of new chemicals in the Euphorbia peplus plant. These chemicals, known as ent-abietane diterpenoid lactones, were separated into a group of eleven never-seen-before ones (1-11) and nine already known ones (12-20). Figuring out their structures and which way the
Imagine if we could create a better way to grow heart cells in a lab. That's exactly what researchers are trying to do with a new combination: graphene and SU-8. They've found that by using graphene, they can help heart cells, called cardiomyocytes, grow faster and communicate better. Graphene, a t
Last week, a weird smell and droplets were found on the International Space Station (ISS) after opening a Russian supply ship. NASA astronaut Don Pettit compared the smell to spray paint. The crew quickly closed the hatch and checked the air. Luckily, the air quality returned to normal the next day.
Scientists have found a clever way to boost the performance of an important enzyme called penicillin G acylase (PGA). They started by collecting tiny magnetic particles, Fe3O4, from nickel slag. Next, they coated these particles with a mix of two polymers: poly (butylene adipate-co-terephthalate) (P
Lately, people have been questioning scientific facts, especially when it comes to COVID, climate change, and conspiracy theories. This raises important questions: What is knowledge? How do we know what we believe? Social epistemology, which studies how we know and believe things, helps us understan
Kiwifruits, popular for their unique taste and nutritional goodness, need to ripen off the vine. The speed of ripening can greatly impact sales. Scientists delved into the molecular factors that control this process to assist farmers. They discovered two key models. One model suggests that when kiwi
Root-knot nematodes are tiny but mighty plant pests that wreak havoc on crops worldwide. Two of the most troublesome species are M. incognita and M. enterolobii, known for their aggressive behavior and ability to invade a wide variety of plants. These microscopic creatures live underground, making d
Have you ever wondered how grapes adapt to different environments? The grapevine, or Vitis species, is known for its adaptability. This adaptability is due to how it responds to its surroundings, a phenomenon called phenotypic plasticity. Scientists studied two grape varieties, Cabernet Sauvignon an
Making semiconductors often leaves tiny issues, like dangling bonds and charge traps, on channels and interfaces. Fixing these can be tough, especially with small structures and thin materials like MoS 2 . High-energy treatments might cause more harm than good. So, scientists turned to hydrogen io
Ever wondered how researchers in urban and demographic studies consume information? One way to find out is by looking at what they cite in their work. A recent study did just that, focusing on articles published in the journal "Estudios Demográficos y Urbanos" from 1998 to 2007. These articles were
