Off the coast of Brittany, France, a team of divers stumbled upon something extraordinary. They found a massive wall, hidden underwater for thousands of years. This wall is not just old; it's ancient, dating back to around 5, 800 to 5, 300 BC. That's right, we're talking about a time when people wer
Office Depot and OfficeMax, two big names in office supplies, are shutting down almost 100 more stores. This is not just a recent thing. It has been going on for a while. The company that owns them, ODP Corporation, has been struggling. This is because people are buying things online more often. The
Offshore oil platforms release a lot of water back into the sea. This water can contain chemicals that don't break down easily. These persistent chemicals can harm the environment for a long time. Scientists needed a better way to find out what's in this water and how dangerous it is. They came up
Concrete structures can be a source of environmental trouble, especially when they come into contact with harmful chemicals like PFAS. These chemicals, often found in firefighting foams, can stick around in concrete and pose risks to the environment. To tackle this issue, researchers explored the us
Concrete is a big deal in construction, especially when it's reinforced with steel. But there's a sneaky problem: corrosion. This is a big issue, especially near the sea. It can lead to massive repair bills. So, how do we spot corrosion before it becomes a major headache? One way is by using a techn
Concrete is a big deal in construction. It is super strong and lasts a long time. But it has a weakness: it isn't great at handling pressure. This limits how it can be used in buildings. To fix this, scientists have been adding tiny particles called carbon nanoparticles to concrete. These particles
Off the coast of Taiwan, a jet trainer, the AT-5 Brave Eagle, took a nosedive on February 15. The plane had just taken off from Chihhang Air Base in southern Taitung when both of its engines gave up the ghost. The pilot, Major-in-Training Lin Wei, had to bail out in a hurry. Lin had over 1, 000 hour
Officer Harmon's journey in "On Call" takes a surprising turn when Lieutenant Bishop denies her transfer request. Harmon, known for her strong moral compass, uses questionable methods to catch a killer. This leads to Bishop's decision, which blocks Harmon's progress but aims to protect the departmen
Offshore oil fields face a big problem when the weather turns bad—microwave signals become unstable and noisy. To fix this, scientists used a method called Lagrange multiplier symplectic singular value mode decomposition to clean up the signal's noise. This was done in five steps: rebuilding the sig
Offline reinforcement learning (RL) faces a big problem: errors can pile up when deep Q functions try to work outside the data they were trained on. This hurts how well the policy can perform on new stuff. Existing methods are too cautious, which isn't great for generalization. But here's an interes
