Can The Human Body Handle Rotating Artificial Gravity?

Posted by in categories: biotech/medical, engineering, space travel

Artificial gravity for spaceflight is a concept older than spaceflight itself, but we’ve only ever seen one small scale test ever flown in space. However decades of research have been performed to show that the human body can adapt to the conditions required for rotating artificial gravity. This shows that it’s an engineering problem that likely solvable for interested parties who want to spend the time, effort and money creating the classic rotating space stations from Science Fiction.

Here’s a couple of papers which were heavily referenced in researching this.

Virtual reality boosts brain rhythms crucial for neuroplasticity, learning and memory

Posted by in categories: biotech/medical, computing, engineering, neuroscience, virtual reality

This is interesting. 😃


A new discovery in rats shows that the brain responds differently in immersive virtual reality environments versus the real world. The finding could help scientists understand how the brain brings together sensory information from different sources to create a cohesive picture of the world around us. It could also pave the way for “virtual reality therapy” for learning and memory-related disorders ranging including ADHD, Autism, Alzheimer’s disease, epilepsy and depression.

Laser mining – the light at the end of the tunnel?

Posted by in categories: chemistry, engineering, government

Laser mining would allow for a no explosive option and not need huge machines increasing output as well. Also lasers could make more precise cuts rather than blades which would never get dull.


The application of the “Graduated Optical Colimator” (GOC) for the mining industry consists of a one-kilowatt optical power fiber laser to selectively spall igneous geological formations containing narrow veins of precious metals.

Scientist Says Astronauts Should Take Psychedelic Mushrooms in Space

Posted by in categories: engineering, environmental, space

Do you agree?


In the future, when space agencies start to send human crews deep into space to explore or terraform distant worlds, we may need to send them off with extra goodies to keep morale high.

When astronauts are feeling lonely, depressed, traumatized, or just generally bad, a little pick-me-up in the form of psychedelic mushrooms could help, mycologist Paul Stamets suggested to Scientific American. It’s an odd idea, but as the body of evidence continues to grow that psilocybin — the active ingredient in shrooms — may have myriad mental health benefits, it may be an odd idea worth considering.

Bio-Inspired, Blood-Repelling Tissue Glue Can Seal Wounds Quickly and Stop Bleeding

Posted by in categories: biotech/medical, engineering

When the resulting paste is applied to a wet surface such as blood-covered tissue, the oil repels the blood and other substances that may be present, allowing the adhesive microparticles to crosslink and form a tight seal over the wound. Within 15 to 30 seconds of applying the glue, with gentle pressure applied, the glue sets and bleeding stops, the researchers showed in tests in rats.


A new adhesive that mimics the sticky substance barnacles use to cling to rocks may offer a better way to treat traumatic injuries.

Inspired by the sticky substance that barnacles use to cling to rocks, MIT

With a single photo, SpaceX sent a not-so-subtle message to FAA regulators

Posted by in categories: engineering, finance, government, space travel

And ArsTechnica seems to be totally missing the point as “delaying” Starship for SOUND AND PRACTICAL SAFETY AND ENVIRONMENTAL QUESTIONS is not ‘delaying’ progress and one needs to simply ask why SpaceX “engineers” can’t up their game enough to actually answer or address those legitimate questions? The answer is rather simple, they probably CAN but the person “in charge” has no with to, incentive to, or will to do so because he sees anyone that questions him as ‘unreasonable opposition’ rather than legitimate concern. Starship could crash and burn on the orbital flight and it would not make a difference at all to the ‘world’ in general. We can and have recovered from worse numerous times while advancing technology and transportation. The FACT that Musk, (and his many rapid fans) somehow “assume” that he and only he can ‘advance’ space access are very much proof that this is not about engineering, ability or purpose but strictly about ego.


To the FAA, Musk seemed to be saying, federal regulators must do their part to ensure the future arrives on schedule. Just as the 20th-century skyscrapers marked the beginning of a new era and eventually launched America into a prosperous future of finance, communication, marketing, and more, the 21st century now beckons.

The skyscraper age will soon give way to the space age.

MIT Researchers Devised a Way To Program Memories Into Bacterial Cells

Posted by in categories: biotech/medical, chemistry, engineering

For several years, Lu’s lab has been working on ways to use DNA to store information such as memory of cellular events. In 2,014 he and Farzadfard developed a way to employ bacteria as a “genomic tape recorder,” engineering E. coli to store long-term memories of events such as a chemical exposure.


Technique for editing bacterial genomes can record interactions between cells, may offer a way to edit genes in the human microbiome.
