We may not yet discover the healing waters of the Fountain of Youth, but one of the accomplishments in this week’s newsletter is unraveling what we know about life and death.
Cutting-edge research in pigs shows that cell death is not instantaneous.
In fact, it’s a complex biological process – a bit like a series of dominoes – that can be stopped.
The results stunned the researchers involved in the project. Check out pig cells, shown at right in the side-by-side comparison above, that have been revived by the OrganEx system, a new technology they developed.
However, the goal is not to magically bring the animals back to life – but rather to expand the window for much-needed human organ transplants.
The power of nature
The massive eruption of an undersea volcano near Tonga in January has defied easy explanation, constantly surprising scientists. his study.
We now know, thanks to discoveries from a NASA satellite, that the volcano released so much water vapor into the atmosphere that it likely temporarily warmed the Earth’s surface.
The NASA’s Artemis mission isn’t just about getting back to the moon — it’s part of the preparations for a more daring plan to go to Mars.
It is uncertain how long the astronauts will make the journey to the Red Planet. One idea is to induce space travelers to hibernate, and a tiny rat-like creature living in the jungle of Patagonia might have a key to unlocking this approach.
Once the weather turns cold, Monito del Monte He builds a mossy nest in the hollow of a tree. There, the small marsupial enters a physiological state called hibernation, and The heart rate drops from 200 beats per minute to two or three beats per minute. During this inactive period, the animal conserves energy, taking a breath once every three minutes.
around the universe
NASA scientists have discovered that walking on a near-Earth asteroid Bennu would be like wading into a ball pit.
Images and data from the agency’s OSIRIS-REx mission revealed that the asteroid’s outer surface is made of loosely bound particles that are not securely bound together.
The OSIRIS-REx spacecraft, which successfully collected a sample of the asteroid in 2020, encountered little resistance when it landed — about the same amount as someone might feel pushing the piston on a French coffee machine.
Coins and priceless gems that once belonged to the Knights of the Seas are among the treasures recently discovered on a Spanish shipwreck.
The Nuestra Senora de las Maravillas (or Our Lady of Wonders) sank in 1656 after colliding with another boat from her fleet and crashing into a reef off the Bahamas.
The 891-ton ship carried huge tonnage, some of which was reserved as royal tax for King Philip IV, from Cuba to Seville, Spain.
