  What If Neurons Could Regenerate? Imagine a world where your brain could heal and renew itself like your skin or liver. How would that change your life? Would you still be the same person, or would you evolve into someone entirely different? Let’s dive into this mind-bending idea together. The top image shows fluorescently labeled cells in the spinal cord of a zebrafish recovering one week after an injury, and the bottom image shows recovery four weeks after an injury. Researchers at Washington University School of Medicine in St. Louis describe the dramatic changes within nerve cells that make regeneration possible. Such findings could inspire the development of new therapies for spinal cord injuries in people.

Learning could become faster and more efficient, making knowledge ret...

SYDNEY – An Australian man lived for 105 days with a titanium heart that uses magnetic levitation technology before receiving a donated human heart, the longest period for a patient with the device implanted, an Australian research group has said. The device was invented by Dr Daniel Timms, founder and chief technology officer of US-Australian medical company BiVacor. It uses a magnetically levitated rotor to pump blood to the body and lungs, employing technology used in maglev trains such as Japan’s Linear Chuo Shinkansen line under construction to link Tokyo and Nagoya. BiVacor worked with international experts, including Professor Toru Masuzawa of Ibaraki University in Japan and an expert in magnetic levitation technology, during the early stages of development, according to the company. The Australian patient in his 40s with severe heart failure underwent a six-hour procedure to implant the artificial heart at St Vincent’s Hospital Sydney on Nov 22, 2024, according to the researc...

The Invisible Coordinate: Exploring the Fourth Dimension in Time and Space  - Arya Bandyopadhyay We experience the world in three dimensions—height, width, and depth. Yet, there exists another fundamental coordinate shaping our reality: time. Traditionally, time is considered the fourth dimension, but another perspective suggests the presence of a mirror universe —a hidden realm that we cannot perceive but that may still influence us. This blog explores both possibilities, examining how science and logic shape our understanding of the unseen dimensions of reality. Photo by Lucas Sandor on Unsplash Aspect 1: Time as the Fourth Dimension Einstein’s theory of relativity reshaped our understanding of time, demonstrating that it is not an independent entity but rather intertwined with space, forming the space-time continuum. Unlike the straightforward flow we perceive, time behaves in complex ways depending on speed, gravity, and quantum mechanics. Time Dilation & Relativ...

Holi Colors to Hair Woes: Why Does Hair Fall After the Festival? Holi brings joy, laughter, and vibrant colors—but for many, it also brings an unexpected problem: hair fall. If you’ve noticed more strands on your pillow or in the shower after Holi, you’re not alone. But why does this happen, and how can you prevent it? Let’s find out. 1. The Harsh Effects of Colors Most Holi colors contain chemicals, heavy metals, and artificial dyes that weaken hair strands. These toxins strip away the hair’s natural moisture, making it dry, brittle, and prone to breakage. What you can do: ✔️ Choose organic or herbal colors to avoid chemical damage. ✔️ Apply coconut or olive oil to your hair before playing to create a protective shield. 2. Excessive Shampooing and Dryness After Holi, most people wash their hair multiple times to remove stubborn colors. But over-washing strips away essential oils, leaving the scalp dry and leading to increased hair fall. How to fix it: ✔️ Use a sulfate-free, mild shamp...

Engineers developed a planning tool that can help independent entities decide when they should invest in joint projects. Date: February 27, 2025 Source: Massachusetts Institute of Technology Summary: A framework helps rail system operators or other planners identify the best joint infrastructure projects to collaborate on with other firms. Their tool can tell an operator how much to invest, the proper time to collaborate, and how the shared profits should be distributed. One large metropolis might have several different train systems, from local intercity lines to commuter trains to longer regional lines. When designing a system of train tracks, stations, and schedules in this network, should rail operators assume each entity operates independently, seeking only to maximize its own revenue? Or that they fully cooperate all the time with a joint plan, putting their own interest aside? In the real world, neither assumption is very realistic. Researchers from MIT and ETH Zurich have devel...

 🌏 The Hidden Side of Retiring Abroad: Social Loneliness Among Expats 💭 Retirement is often seen as the golden period of life—a time to explore new places, embrace different cultures, and finally live free of professional obligations.

TOPIC: The Silent Battle: Body-Brain Communication Diseases That Are Often Misdiagnosed Introduction Have you ever experienced persistent physical symptoms, visited multiple doctors, undergone countless tests—only to be told, “Everything looks normal”? If so, you’re not alone. Many conditions affecting millions worldwide are not just body diseases or mental illnesses , but a complex interplay between the brain and body . The human body operates as an integrated system, with the brain acting as a control center for vital functions, pain perception, immune response, and even digestion. When this delicate communication system is disrupted, it can manifest as physical symptoms that are frequently misdiagnosed or oversimplified as bodily issues . These conditions, often dismissed or misunderstood, require a more holistic perspective for proper recognition and treatment. Let’s explore some of the most misunderstood body-brain communication diseases and uncover the true nature of these co...
