The roadmap to promote neural repair after spinal cord injury remains elusive. Here, longitudinal single-cell sequencing in adult zebrafish identifies intersecting modes of neuronal plasticity and neurogenesis during innate neural repair.

Personal identity seems so strong. We have the same sense of ourselves throughout our lives, even though everything about our physical bodies and brains is changing constantly. What then causes the continuity of personal identity? Where does transhumanism fit in? Some say personal identity is an illusion, but that seems like cheating. Others credit a nonphysical soul. That seems as though it’s cheating too.

A new theory suggests time travel might be possible without creating paradoxes.
TL;DR:
A physics student from the University of Queensland, Germain Tobar, has developed a groundbreaking theory that could make time travel possible without creating paradoxes. Tobar’s calculations suggest that space-time can adjust itself to avoid inconsistencies, meaning that even if a time traveler were to change the past, the universe would correct itself to prevent any disruptions to the timeline. This theory offers a new perspective on time loops and free will, aligning with Einstein’s predictions. While the math is sound, actual time travel remains a distant possibility.
Scientists have sequenced the largest known animal genome — and it’s 30 times bigger than the human genome.
The genome belongs to the South American lungfish (Lepidosiren paradoxa), a primeval, air-breathing fish that “hops” onto land from the water using weird, limb-like fins. The fish’s DNA code expanded dramatically over the past 100 million years of evolutionary history, racking up the equivalent of one human genome every 10 million years, researchers found.
To make quantum computing succeed, we need to step back from the unseemly rush towards hype and stock-price boosts that has characterized other new markets.
During the Cold War Era of the 1960s, Russian researchers were looking for ways to support the immune system in conditions running the gamut from cancer to bio-warfare agents. Eastern Europeans, with a cultural love of fermented milk products, logically looked to probiotics, or lactobacillus, for immune support because it was safe, cheap and effective.
A Bulgarian researcher and medical doctor, Dr. Ivan Bogdanov, researched lactobacillus bacteria in the 1960s. Bogdanov believed that specific strains of probiotics could have anti-tumor properties.
The doctor’s research team injected mice with a sarcoma cancer, then administered a crude mixture of cell fragments from a strain of Lactobacillus delbrukii. Bogdanov observed that the cancer disappeared within a few days. Subsequently, researchers attempted to re-grow cancer in the same mice, but without success — the mice seemed immune to the cancer cells.
A single jar of honey can reveal more about our environment than we ever imagined, finds Graham Lawton.
The specimens provide insight into how tardigrades evolved cryptobiosis, a temporary and almost complete shutdown of bodily processes.
People whose eyes dilated more performed better on tests of working memory.
