NASA astronauts could hibernate on deep space missions thanks to arctic squirrels

Posted by in categories: health, space

Researchers are studying hibernating Arctic ground squirrels with the goal of harnessing the benefits of this odd natural state to protect astronauts’ health on long-duration space missions.

Hibernation is not just sleep. In fact, it’s quite different from sleep. While we sleep, our brains fire up and become highly active; in hibernation, on the contrary, brain activity completely slows down. The body temperature of hibernating animals also drops, in some cases close to the freezing point, cells stop dividing and heart rate decreases to two beats per minute.

Scientists Successfully Sent A Particle Back in Time Using A Quantum Computer

Posted by in categories: computing, information science, particle physics, quantum physics, time travel

As fantastic as this may seem this is not an impossible occurrence.


Before Einstein, time travel was just a story, but his calculations led us into the quantum world and gave us a more complicated picture of time. Kurt Godel found that Einstein’s equations made it possible to go back in time. What’s up? None of the ideas about how to go back in time were ever physically possible.

Before sending a particle back in time, scientists from ETH Zurich, Argonne National Laboratory, and Moscow Institute of Physics and Technology asked, Why stick to physical grounds?

The Universe Is Too Smooth

Posted by in category: cosmology

Results from a complex new analysis support cosmologists’ suspicions that something is missing from our understanding of the universe.

For the most part, our standard theory of cosmology fits observations like a glove. With just a handful of ingredients, scientists can explain the patchy pattern of the cosmic microwave background (CMB) — the relic radiation from the universe’s primordial age — and how the nearly uniform soup it came from transformed into the Swiss cheese of galaxy clusters and cosmic voids we see today.

But some nagging problems remain. The most touted is the Hubble tension, a discrepancy between how fast the universe appears to be expanding today and how fast it “should” be expanding, based on what we see in the early universe. But there’s another, more subtle discrepancy: Today’s universe is too smooth.

Scientists claim Earth’s inner core has reversed its direction of spin

Posted by in category: space

The Earth’s core may have stopped spinning, or may even now be spinning backwards, according to a new study.

The core of our planet is made up of an outer layer of liquid metal, and an inner core of solid metal that is about 70 per cent the size of the Moon.

It is generally believed that the core rotates counter-clockwise when viewed from the North Pole, like the rest of planet Earth.
