Advanced Tech and Life Science on Station Today Promoting Health

Posted by in categories: 3D printing, bioprinting, biotech/medical, health, nanotechnology, science, space travel

Nanomaterials manufacturing, 3D bioprinting, and astronaut eye health were the main research topics aboard the International Space Station on Friday. The Expedition 71 crew members also continued servicing spacesuits and conducted an emergency drill.

The SpaceX Dragon cargo spacecraft recently delivered to the orbital outpost a biotechnology study to demonstrate the in-space production of nanomaterials that mimic DNA. NASA Flight Engineers Jeanette Epps and Mike Barratt worked on the second portion of that experiment on Thursday mixing then treating the research samples for analysis. Epps began her day mixing solutions in the Life Science Glovebox to create specialized nanomaterials. During the afternoon, Barratt applied sound and light treatments to the samples then stowed them aboard Dragon for analysis back on Earth. Results may lead to advanced therapies for space-caused and Earthbound health conditions.

The duo partnered back together at the end of the day for eye scans using standard medical imaging gear found in an optometrist’s on Earth. Barratt operated the hardware with guidance from doctors on the ground peering into Epp’s eyes and examining her retina and optic nerve for the B Complex eye health investigation.

New study finds potential targets at chromosome ends for degenerative disease prevention

Posted by in categories: biotech/medical, genetics, life extension

We depend on our cells being able to divide and multiply, whether it’s to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied in a complete way during cell division. Telomeres, which cap the ends of chromosomes, play a critical role in this cell-renewal process—with a direct bearing on health and disease.

Potential advancement in medicinal use of THC and reduction of risks in recreational use

Posted by in categories: biotech/medical, neuroscience

“This study is a first step in uncovering how we can mitigate risks of THC when used in medicine, and also is targeted at making cannabis safer for the general, non-therapeutic consumer,” said Dr. Tory Spindle.

Can cannabis be modified to decrease certain side effects, specifically anxiety, that is caused by tetrahydrocannabinol (THC)? This is what a recent study published in Drug and Alcohol Dependence hopes to address as a team of researchers led by the Johns Hopkins University School of Medicine investigated whether adding d-limonene, which is a known cannabis oil, to THC could help alleviate common feelings of anxiety or paranoia that cannabis users traditionally experience. This study holds the potential to help improve medicinal cannabis while decreasing risks to users of recreational cannabis, as well.

For the study, the researchers enlisted 20 healthy adult participants with an average age of 26 years old who completed 10 six-hour sessions involving them using vaporized THC alone (15 mg or 30 mg), vaporized d-limonene alone (1 mg or 5 mg), both together, and finally a placebo. The sessions were double-blinded, meaning both the researchers and participants were unaware who was vaporizing which sample.
