Tardigrades: The Micro World Meets the Macro World

Tardigrades are some of the most resilient creates on our planet. They are able to survive extreme situations by going into a sort of hibernation. These beings offer hope for finding life on other (more desolate) worlds in our solar system.


First Genetic Results From Scott Kelly's Year In Space Reveal DNA Mysteries

After recent events, we’re all ready to hop aboard the next flight to Mars. But before us Earthlings embark on a seven-month journey to the Red Planet, we need to understand how the harsh conditions of space can affect our bodies.


First human-pig 'chimera' created in milestone study | Science

Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants.



It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera – named after the cross-species beast of Greek mythology – has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch.


This new 3D printer makes life-sized ear, muscle, and bone tissues from living cells - ScienceAlert

For the first time, scientists have used a 3D printer to produce life-sized body parts and tissues using living cells as the 'ink'. Not only are these structures large and sturdy enough to be a viable replacement for the real thing - something that previous bioprinters have failed to do - they're personalised and functional, not a 'one size fits all' cosmetic add-on.

Why do we get scared at a haunted house?- Evolution answers! – Skit Hub

Why Nature Preferred DNA over RNA? | Science Samhita

It is a well-known fact that DNA acts as a genetic material in most of the organisms on this planet earth. However, it is also clear that RNA also acts a genetic material, but only in some viruses (for example, Tobacco Mosaic Viruses, QB Bacteriophage, etc.). Now, the question that arises here is that, “Why Nature preferred DNA over RNA?”

Frozen Tardigrade Brought Back to Life After 30 Years

Researchers at the National Institute of Polar Research in Tokyo defrosted and revived two of the tiny animals, which are also known as water bears, from a batch collected in the Antarctic in 1983, The Asahi Shimbun newspaper reports. While one tardigrade died after 20 days, the other began reproducing. It laid 19 eggs, of which 14 hatched successfully.
