Viewed face-on, grand spiral galaxy NGC 5643 has a festive appearance in this colorful cosmic portrait. Some 55 million light-years distant, the galaxy extends for over 100,000 light-years, seen within the boundaries of the southern constellation Lupus. Its inner 40,000 light-years are shown in sharp detail in this composite of Hubble Space Telescope image data. The galaxy’s magnificent spiral arms wind from a yellowish central region dominated by light from old stars, while the spiral arms themselves are traced by dust lanes, young blue stars and reddish star forming regions. The bright compact core of NGC 5643 is also known as a strong emitter of radio waves and X-rays. In fact, NGC 5643 is one of the closest examples of the Seyfert class of active galaxies, where vast amounts of dust and gas are thought to be falling into a central massive black hole.

Why is a science blog named after a motor neuron? Fair question. If you landed here expecting car parts or motor repairs, I'm sorry...and also, stay. You might find something more interesting. Fusimotor neurons are a type of nerve cell in your body right now, quietly doing one of the most elegant jobs in neuroscience. They don't move your muscles directly. Instead, they adjust the sensitivity of your muscle spindles — the tiny stretch receptors embedded in your muscle fibers. In plain terms: they set the dial on how aware your nervous system is of its own body. They are the hidden calibrators of human movement, and almost nobody knows they exist. That's exactly why I named this blog after them. The best science isn't always the most famous science. Some of the most fascinating things happening inside the human body — inside your body — are invisible, unnamed, and completely overlooked. This blog exists to change that. I am a collection of water, calcium and organic molecules, but not a single one of the cells that compose me knows who I am, or cares...So why should you? Maybe because the story of what we are is more interesting than the story of who we are. That's what this blog is about. New posts go up every Tuesday and Friday. No newsletters, no algorithms — just good science writing, when you come looking for it. If you're curious about a topic, feel free to reach out. Some of my best posts have started with a reader's question. Welcome to myfusimotors. The hidden calibrators sent me. Corina.

It seems strange that God made the universe so big but only put life on earth. This question baffles me

The universe appears to operate under consistent laws, with no verifiable proof of divine influence.

Can science ever fully explain the origins and workings of the universe?

While science may never provide a complete and final explanation of the universe’s origins and workings, it remains humanity’s most powerful tool for unraveling the mysteries of existence.

This lack of verifiable proof does not necessarily negate the possibility of divine influence.
