We may not yet have discovered the healing waters of the fountain of youth, but one of the breakthroughs in this week’s newsletter is shaking up what we know about life and death.
Cutting-edge research in pigs shows that death in cells is not instantaneous.
In fact, it’s a complex biological process – a bit like a cascade of dominoes – that can potentially be stopped.
The results surprised the researchers involved in the project. Check out the pig cells, pictured on the right in the side-by-side comparison above, being revived by the OrganEx system, a new technology they developed.
The goal, however, is not to magically bring animals back to life, but to widen the window for much-needed human organ transplants.
Force of nature
The massive eruption of an undersea volcano near Tonga in January defied easy explanation, constantly surprising scientists who continue to study it.
We now know that thanks to detections from a NASA satellite, the volcano has spewed such a massive amount of water vapor into the atmosphere that it is likely to temporarily heat the Earth’s surface.
The NASA’s Artemis mission isn’t just about returning to the Moon — it’s part of the preparations for a bolder plan to go to Mars.
How the astronauts will make the years-long journey to the Red Planet is uncertain. One idea is to induce hibernation in space travelers, and a tiny mouse-like creature that lives in the Patagonian forest might hold a key to unlocking this approach.
Once the weather turns cold, the monito del goes up to bug eyes builds a mossy nest in a tree hollow. There, the tiny marsupial enters a physiological state called torpor, and his heart rate drops from 200 beats per minute to two or three beats per minute. During this period of inactivity, the animal conserves its energy by breathing once every three minutes.

Walking on Bennu, a near-Earth asteroid, would be a bit like wading through a bullet pit, NASA scientists have found.
Images and data from the agency’s OSIRIS-REx mission revealed that the asteroid’s exterior is made up of loose particles that are not bound tightly.
The OSIRIS-REx spacecraft, which in 2020 successfully collected a sample from the asteroid, encountered little resistance upon landing – about the same amount someone might feel when pressing down on the piston. a French press coffee maker.

Priceless coins and jewelry that once belonged to sea knights are among the treasures recently discovered on a Spanish shipwreck.
The Nuestra Señora de las Maravillas (or Our Lady of Wonders) sank in 1656 after colliding with another ship in her fleet and crashing into a coral reef off the Bahamas.
The 891-ton ship was carrying a huge treasure, part of which was reserved as royal tax for King Philip IV, from Cuba to Seville, Spain.
