The role of Newtic1 protein in limb regeneration in adult newts

Year 2022 This new protein Newtic1 holds promise to fully understanding limb regeneration in humans. Still though genetic engineering will be needed to fully integrate the ability for limb and body part regeneration.

The animal kingdom exhibits a plethora of unique and surprising phenomena or abilities that include, for some animals, the ability to regenerate body parts irrespective of age. Now, researchers from Japan have discovered that the mechanisms behind this peculiar ability in newts have a few surprises of their own.

Hydras can regrow their heads. Scientists want to know how they do it

Year 2021 😗

Hydra belong to a larger group of invertebrates called cnidarians, which also includes sea anemones, corals, and jellyfish. Their simple bodies have a tubelike shape with the mouthpart and tentacles at one end, and a “foot” that attaches to the surrounding rock or other solid surface at the other.

Some animals such as lizards and salamanders can regrow lost limbs. But hydra, along with some worms and other animals, take regeneration to the extreme. Near their mouthparts, hydra have a cluster of 50 to 300 cells called the head organizer; as its name implies, it directs the development of the head. If a hydra is beheaded, a new organizer can form and prompt the animal to regrow its head. Meanwhile, the head that was lopped off will sometimes regrow the lower portion of its body.

Scientists have also successfully grafted hydra heads onto the decapitated bodies of other hydra. And if a hydra is torn into small clumps of cells, those clumps that include head organizer cells will regrow a full body, Macias-Muñoz says.

Transcriptomic landscape of the blastema niche in regenerating adult axolotl limbs at single-cell resolution Communications

face_with_colon_three Year 2018 This detailed information about axoxtl limb regeneration is giving scientists a better understanding of how this remarkable can regenerate and eventually it will help humans regenerate lost limbs too.

Limb regeneration requires a blastema with progenitor cells, immune cells, and an overlying wound epidermis, but molecular identities of these populations are unclear. Here, the authors use single-cell RNA-sequencing to identify transcriptionally distinct cell populations in adult axolotl limb blastemas.

New nanoparticle source generates high-frequency light

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

So violet can show you smaller details than , for example, because it has a shorter . But to see really, really small things—down to the scale of billionths of a meter, thousands of times less than the width of a human hair—to see those things, you need extreme ultraviolet light (and a good microscope).

Extreme ultraviolet light, with wavelengths between 10 and 120 nanometers, has many applications in , studying biological objects, and deciphering the fine details of computer chips during their manufacture. However, producing small and affordable sources of this light has been very challenging.

New DNA Research Changes Origin of Human Species

New model for human evolution suggests Homo sapiens arose from multiple closely related populations.

A new study in Nature challenges prevailing theories, suggesting that Homo sapiens evolved from multiple diverse populations across Africa, with the earliest detectable split occurring 120,000–135,000 years ago, after prolonged periods of genetic intermixing.

In testing the genetic material of current populations in Africa and comparing it against existing fossil evidence of early Homo sapiens populations there, researchers have uncovered a new model of human evolution — overturning previous beliefs that a single African population gave rise to all humans. The new research was published on May 17, in the journal Nature.

Save the date: Rejuvenation Startup Summit 2024: May 10–11 in Berlin

The Forever Healthy Foundation is pleased to announce the second edition of the Rejuvenation Startup Summit, following the inaugural Rejuvenation Startup Summit in 2022 with more than 400 participants from over 30 countries. It will take place on 10–11 May 2024 in Berlin. The Rejuvenation Startup Summit is the world’s largest in-person gathering of longevity startups. It brings together startups, members of the longevity venture capital / investor ecosystem, and researchers interested in starting or joining a startup – all with the goal of accelerating the development of the rejuvenation biotech industry.

Will My Son’s Blood Make Me Younger?

At Blueprint we’ve explored and evaluated hundreds of anti-aging therapies.

Recently, we had a daring idea: what if my father, son and I completed the world’s first ever multi-generational plasma exchange?

Plasma is the yellowish, liquid part of your blood. There is emerging evidence that plasma exchanges may offer various health benefits.

Nervous but excited, we travelled to a transfusion centre in Dallas Texas to make it happen.


I’ve invested millions of dollars building the world’s leading anti-aging protocol, becoming the most measured human in history. Blueprint is an algorithm, built by science, that takes better care of me than I can myself.

And it’s available to you for free. Check out the Blueprint website for recipes, exercise, and other protocols. Become the next evolution of human.

Will AI Produce Useless Humans?

The other day a friend proudly told me she wrote a heartwarming graduation card to her teenage son. “Okay,” she confessed. “I

How long was your card? I asked her.

Not only that, but many also couldn’t even generate a topic on their own. They lacked creativity to dream up their own ideas, much less the critical thinking skills to put themselves in the shoes of their audience, imagining what would land. But they all had 4.0 GPAs or higher and came from private schools in Orange County and LA, reflecting our watered-down educational system.

And now we’re being told ChatGPT is a boon for our students?

Despite these concerns, our best days are ahead of us. As a positive futurist, I see the AI surge as a wakeup call. Especially in corporate America. For too long, we’ve outsourced too much. As just one example, the COVID-19 pandemic exposed how reliant we are on countries like China for manufacturing, including our critical medical supply chain.
