Overview of Five major techniques used in brain imaging, each with its unique purpose, strengths, and limitations:
1. X-Ray
Use: Primarily for imaging bones; not ideal for soft tissue like the brain.
Fact: X-rays pass through soft tissue but are absorbed by denser structures like bone, making them suitable for detecting skull fractures.
Limitation: Cannot show brain structures or abnormalities in detail.
---
2. CT (Computed Tomography) Scan
Use: Cross-sectional images of the brain using X-ray technology.
Fact: Good for detecting bleeding, tumors, and skull fractures.
Limitation: Less detail on soft tissues compared to MRI.
---
3. MRI (Magnetic Resonance Imaging)
Use: Provides detailed images of brain soft tissues using magnetic fields and radio waves.
Fact: Excellent for detecting tumors, brain injuries, developmental anomalies, and multiple sclerosis.
Limitation: More expensive and time-consuming than CT.
---
4. MRA (Magnetic Resonance Angiography)
Use: Visualizes blood vessels in the brain.
Fact: Often used to detect aneurysms, blockages, or vascular malformations.
Limitation: Requires specialized equipment and often a contrast agent.
---
5. PET Scan (Positron Emission Tomography)
Use: Assesses brain metabolism and activity.
Fact: Commonly used in Alzheimer's research, cancer detection, and epilepsy diagnosis.
Limitation: Involves radioactive tracers and is less spatially detailed than MRI.Overview of Five major techniques used in brain imaging, each with its unique purpose, strengths, and limitations: 1.

Looking for a delicious dessert to impress your guests?
Flan de Coco
Ingredients:
- 1 can (14 oz) coconut milk
- 1 can (12 oz) evaporated milk
- 1 can (sweetened) condensed milk
- 4 large eggs
- 1 cup sugar (for caramel)
- 1 tsp vanilla extract
- Pinch of salt
Preparation Steps:
1. Preheat your oven to 350°F (175°C).
2. In a saucepan, melt the sugar over medium heat until it turns golden brown; pour it into a flan mold to coat the bottom.
3. In a mixing bowl, whisk together coconut milk, evaporated milk, condensed milk, eggs, vanilla extract, and salt until well combined.
4. Pour the mixture into the caramel-coated mold.
5. Place the mold in a larger baking dish and fill the dish with water until it reaches halfway up the sides of the flan mold.
6. Bake in the preheated oven for about 60 minutes, or until set (a knife inserted should come out clean).
7. Remove from the oven and let it cool to room temperature; then refrigerate for a few hours.
8. To serve, run a knife around the edges and invert onto a plate.
Prep Time: 15 mins | Cooking Time: 60 mins | Total Time: 1 hr 15 mins
Calories: 220 kcal per serving | Servings: 8 servings

Apple's latest AI research challenges the hype around Artificial General Intelligence (AGI), revealing that today’s top models fail basic reasoning tasks once complexity increases. By designing new logic puzzles insulated from training data contamination, Apple evaluated models like Claude Thinking, DeepSeek-R1, and o3-mini. The findings were stark: model accuracy dropped to 0% on harder tasks, even when given clear step-by-step instructions. This suggests that current AI systems rely heavily on pattern matching and memorization, rather than actual understanding or reasoning.
The research outlines three performance phases—easy puzzles were solved decently, medium ones showed minimal improvement, and difficult problems led to complete failure. Neither more compute nor prompt engineering could close this gap. According to Apple, this means that the metrics used today may dangerously overstate AI’s capabilities, giving a false impression of progress toward AGI. In reality, we may still be far from machines that can truly think.
