Nitrogen is a big player in how atmospheric organic aerosols (OAs) absorb sunlight. These tiny particles in the air affect Earth's climate. But, the way they change and absorb light is still a mystery. Scientists have found that brown nitrogen (BrN), a nitrogen-rich part of OAs, is the main absorb
COVID-19 has left many people with lingering health issues, even after the virus is gone. One big problem is that the blood vessels in some people don't work as well as they should. This can make simple tasks, like walking up stairs, feel much harder. But here's where it gets interesting: exercise m
Rolls-Royce, a big name in making jet engines and power systems for ships and submarines, just had a fantastic year. They made a whopping £2. 46 billion in operating profit for 2024. That's a huge jump of 57% from the year before. This big success allowed them to set even higher go
Imagine this: a city buried under ash, people frozen in time, and a brain turned into glass. This isn't a sci-fi movie, but a real event that happened in 79 AD when Mount Vesuvius erupted. The eruption was so powerful that it released energy equal to 100, 000 Hiroshima bombs. The cities of Pompeii a
The clock is ticking down to the end of the first six-week pause in fighting between Israel and Gaza. People on both sides are feeling the stress. This pause was meant to give time for talks to move forward. But so far, there hasn't been much progress. This leaves both Israelis and Palestinians
Sumatran orangutans, those amazing tree-dwelling primates from Indonesia, have a secret problem. They are carrying bacteria that can cause serious infections in humans. One of these bacteria is called Klebsiella pneumoniae, a common germ found in many mammals, including orangutans. This bac
Dibrugarh, a city in the northeastern part of India, has been under the microscope for its air quality. Scientists have been keeping an eye on tiny particles called aerosols that float around in the air. These aerosols can mess with the environment in both the short and long term. Understanding how
Imagine this: a tense border crossing, bodies being handed over, and prisoners set to walk free. This isn't a scene from a movie, but a real-life situation. It all started with Hamas giving four bodies to the Red Cross. These bodies are believed to be Israeli hostages. This wasn't a random act. It w
Imagine this: humans thriving in lush rainforests way back when. The conventional wisdom was that humans started living in rainforests around 70, 000 years ago. But hold onto your hats, folks, because new findings suggest that humans were living in rainforests as early as 150, 000 years ago. This re
The soybean industry faces a significant threat from Phytophthora root and stem rot, causing massive financial losses globally. Researchers have developed a clever solution using a machine learning model. This model, based on a heterogeneous interaction graph attention network, was trained and teste
