Here’s Why Hibernation in Space May Not Be Possible For Humans After All

Posted by in categories: cosmology, space travel

Sending humans virtually anywhere in space beyond the Moon pushes logistics of health, food, and psychology to limits we’re only just beginning to grasp.

A staple solution to these problems in science fiction is to simply put the void-travelers to bed for a while. In a sleep-like state akin to hibernation or torpor, metabolism drops, and the mind is spared the boredom of waiting out endless empty hours.

Unlike faster-than-light travel and wormholes, the premise of putting astronauts into a form of hibernation feels like it’s within grasp. Enough so that even the European Space Agency is seriously looking into the science behind it.

Jeff Bezos Loses $13 Billion in Hours as Amazon Shares Slump

Posted by in category: energy

Amazon slid 14%, pulling Nasdaq 100 to lowest since March 2021.


Jeff Bezos saw $20.5 billion of his fortune melt away after Amazon.com Inc.’s results left investors disappointed, helping fuel the worst month for technology stocks in years.

Shares of the e-commerce company were down 14% on Friday after it reported a quarterly loss and the slowest sales growth since 2001. Bezos’s net worth fell to $148.4 billion, according to the Bloomberg Billionaires Index, from a peak this year of more than $210 billion.

NASA’s Webb In Full Focus, Ready for Instrument Commissioning

Posted by in category: space

Alignment of NASA’s James Webb Space Telescope is now complete. After full review, the observatory has been confirmed to be capable of capturing crisp, well-focused images with each of its four powerful onboard science instruments. Upon completing the seventh and final stage of telescope alignment, the team held a set of key decision meetings and unanimously agreed that Webb is ready to move forward into its next and final series of preparations, known as science instrument commissioning. This process will take about two months before scientific operations begin in the summer.

The alignment of the telescope across all of Webb’s instruments can be seen in a series of images that captures the observatory’s full field of view.

Elon Musk’s SpaceX Shuts Down Russian Jamming Attack!

When it comes to responding to emerging threats, the Pentagon’s director for electromagnetic warfare suggested today that the US military’s electronic warfare organization should borrow a leaf from SpaceX.

SpaceX founder Elon Musk said that Russia had jammed Starlink terminals in Ukraine for hours at a time after SpaceX shipped Starlink terminals to Ukraine in February in an apparent effort to help Ukraine preserve its internet connection amid the war with Russia. Starlink was back up and running after a software upgrade, according to Musk, who added on March 25 that the constellation had “resisted all hacking & jamming attempts” in Ukraine.

How An “Ocean” in Your Brain Helps Transmit Information

Posted by in categories: biological, computing, neuroscience

For years, the brain has been thought of as a biological computer that processes information through traditional circuits, whereby data zips straight from one cell to another. While that model is still accurate, a new study led by Salk Professor Thomas Albright and Staff Scientist Sergei Gepshtein shows that there’s also a second, very different way that the brain parses information: through the interactions of waves of neural activity. The findings, published in Science Advances on April 22, 2022, help researchers better understand how the brain processes information.

“We now have a new understanding of how the computational machinery of the brain is working,” says Albright, the Conrad T. Prebys Chair in Vision Research and director of Salk’s Vision Center Laboratory. “The model helps explain how the brain’s underlying state can change, affecting people’s attention, focus, or ability to process information.”

Researchers have long known that waves of electrical activity exist in the brain, both during sleep and wakefulness. But the underlying theories as to how the brain processes information—particularly sensory information, like the sight of a light or the sound of a bell—have revolved around information being detected by specialized brain cells and then shuttled from one neuron to the next like a relay.
