1. Scientists reveal the best exercise for knee arthritis pain relief

   A major review of 217 trials shows that aerobic exercise is the most effective option for managing knee osteoarthritis. Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement. While alternatives like strength training and mind-body exercises help, they are best used alongside aerobic workouts. The findings also confirm that exercise is a safe and essential part of treatment.

2. Earth is splitting open beneath the Pacific Northwest, scientists say

   For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor. Using advanced seismic imaging, they found the Juan de Fuca plate splitting into fragments as it sinks beneath North America. Rather than collapsing all at once, the plate is tearing piece by piece, like a train slowly derailing. The finding helps explain ancient plate fragments and could refine how scientists understand earthquake behavior.

3. Scientists restore memory by blocking a single Alzheimer’s protein

   Researchers have identified a new potential weapon against Alzheimer’s: blocking a protein called PTP1B. In mice, this approach boosted memory and helped brain immune cells clear harmful plaque buildup. Since PTP1B is also linked to diabetes and obesity—both risk factors for Alzheimer’s—it could offer a broader treatment strategy.

4. This AI knew the answers but didn’t understand the questions

   For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention. A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks. But new research is challenging that bold claim, suggesting the model isn’t truly “thinking” at all—it’s just memorizing patterns.

5. A photon was teleported across 270 meters in stunning quantum breakthrough

   Scientists have pulled off a first: teleporting a photon’s state between two separate quantum dots. This was done over a 270-meter open-air link, proving quantum information can travel between independent devices. The achievement marks a key step toward building quantum networks for ultra-secure communication. It also sets the stage for more advanced systems like quantum relays.
