Food science engineer and Cornell University professor Syed Rizvi was recently awarded a patent for the ‘instant ice cream’ machine he invented, which can create the delicious frozen treat from an ice cream mix in just three seconds. I can’t even imagine how much ice cream I’d be eating if I could make at home myself in mere seconds. I shiver at the thought. And not just because ice cream is so cold.
“In the traditional method of making ice cream, the dairy-based mix flows through a heat-exchanging barrel, where ice crystals form and get scraped by blades.
With this new method, highly pressurized carbon dioxide passes over a nozzle that, in turn, creates a vacuum to draw in the liquid ice cream. When carbon dioxide goes from a high pressure to a lower pressure, it cools the mixture to about -70°C, freezing the mixture into ice cream, which jets out of another nozzle into a bowl, ready to eat.”
Syed imagines his invention helping to reduce the need for the long distance “cold chain” transportation of ice cream (which requires ice cream be maintained at -20°C), and the massive amount of energy used during that process. And since the ice cream isn’t traveling far from its origin to my stomach, the addition of undesirable stabilizing and emulsifying ingredients could be eliminated as well. Win/win! So, how much for a personal size instant ice cream machine, and how quickly can you have it installed next to my bed?

The Key For Ending Extinction? 46,000 Years Frozen Animal Ressurrected In Siberia
Posted in: Today's ChiliScientists have achieved a remarkable feat by resurrecting an extinct animal that had been frozen for a staggering 46,000 years in Siberia. The subject of this extraordinary discovery is the tiny creature known as nematodes, found within the permafrost alongside Siberia’s northern Kolyma River.
The radiocarbon analysis of the nematodes revealed that they originated from a prehistoric era when Neanderthals and dire wolves roamed the Earth. These ancient nematodes belong to a previously unknown functionally extinct species called Panagrolaimus kolymaensis. Their existence presents a unique opportunity to delve into the mysteries of evolution and the secrets of the past.

A Journey through Time: Suspended Animation
The significance of the discovery lies in the nematodes’ ability to enter a state of suspended animation known as “cryobiosis.” In this state, their metabolic systems shut down, and they become desiccated husks capable of being revived when favorable conditions return. Astonishingly, these nematodes had spent an astounding 40,000 years in this suspended state, effectively pausing their evolution for millennia.
The Adaptive Wonders of Nematodes
Nematodes, also known as roundworms, are an incredibly adaptable group of creatures, with some species being microscopic, while a few can be seen with the naked eye. Their ability to survive freezing temperatures through cryobiosis offers invaluable insights into the resilience and adaptability of species in extreme conditions. Studying these ancient nematodes provides us with a glimpse into the past and a better understanding of how certain resilient species endure challenging circumstances.

Resurrection of Extinct Lineages
The revival of P. kolymaensis is not an isolated case; Scientists have previously managed to resurrect various organisms from the distant past, including bacterial species that existed over 25 million years ago. The discovery of these ancient nematodes in the Siberian permafrost has extended the timeline of revival several millennia further. Each revival provides researchers with new knowledge about the behavior and survival mechanisms of long-gone species.
The Enigmatic Evolutionary Processes
The nematodes’ resurrection opens up new avenues of research into evolutionary processes. These creatures offer insights into how generation times can span from mere days to millennia and how the long-term survival of individuals can lead to the revival of otherwise extinct lineages. Studying these unique cases allows scientists to piece together the puzzle of evolution and its complexities.

Implications for the Future
As habitats around the world become increasingly extreme due to global changes, understanding cryptobiosis becomes more crucial than ever. Research on suspended animation and species survival in extreme conditions can shed light on how various life forms may evolve and adapt in the face of environmental challenges. The knowledge gained from studying ancient nematodes could potentially inform strategies for preserving biodiversity and mitigating the effects of climate change.
The resurrection of 46,000-year-old nematodes from the Siberian permafrost is a testament to the resilience and adaptability of life on Earth. These ancient creatures provide invaluable insights into evolutionary processes, offering a window into the past and raising intriguing implications for the future of life on our planet.
As we strive to understand and protect our environment, the study of these tiny organisms can prove to be a significant piece of the puzzle in preserving life’s diversity for generations to come.
