Cool Science thread

[SkiBall]

Good discussion about that^^ from one of the Curiosity SAM team members: https://phys.org/news/2018-06-geobio...mons-mars.html

TL;DR summary: Not evidence of life at this time, but the discovery strongly validates future plans to bring samples back to Earth for more sophisticated analysis.

What was that recent movie when they opened the pod landing at the end but shouldn't have? I can't help but think of that. Damn movies.

Looked it up:
Life

"No science-fiction movie that takes place at the International Space Station has been quite as terrifying as "Life," a new space thriller that comes out in theaters today (March 24).

In the film, a Mars sample-return mission delivers the first proof of alien life to a group of astronauts at the International Space Station (ISS). What is at first a harmless, single-celled organism sealed inside a box in the lab grows bigger, stronger, smarter and bloodthirsty. When it breaks out of its container and comes after the astronauts, all hell breaks loose. "



Yeah, so that.

Does it first rip the clothes off of the smokin' hot blonde Russion cosmonaut and ass-fuck her before killing everyone? Otherwise, I think I'll pass.

DTM, that TB vaccine (live attenuated BCG bactreia) has also been used to treat bladder cancer for the last ~30+yrs.

and more bugs as drugs, highlighting the intersection between diet, microbiome composition, and immune function: http://stm.sciencemag.org/content/10/446/eaau0471.full

The ketogenic diet (KD) is a high-fat, low-carbohydrate diet that originally found prominence as a treatment for pediatric epilepsy and is now also being used as part of therapy for cancer, Alzheimer’s disease, metabolic syndrome, and autism spectrum disorders. However, the underlying mechanisms of the KD on neurological function are still not entirely clear. Olson et al. used a mouse model of refractory epilepsy to investigate the antiepileptic mechanisms of the KD. The authors first showed that the KD rapidly (within 4 days) altered the gut microbiota, specifically by increasing Akkermansia muciniphila and Parabecteroides. The KD increased seizure threshold to electrical stimulation; however, when KD-fed mice were treated with antibiotics to reduce intestinal bacteria, the seizure threshold returned to control levels. Similarly, in germ-free mice without a gut microbiota, KD did not modulate seizure threshold. Antibiotic-treated mice could have seizure protection restored by feeding with A. muciniphila and Parabecteroides, but not with either bacteria alone or with other bacteria. Administering A. muciniphila and Parabecteroides to mice fed with a normal diet provided a degree of protection against seizures, suggesting that the gut microbiota changes were responsible for the therapeutic effects produced by the KD, rather than the restriction of carbohydrates or the production of ketones. The authors then replicated these findings in a genetic mouse model of temporal lobe epilepsy, demonstrating a significant effect of the gut microbiota on seizure susceptibility in epilepsy of multiple etiologies. Metabolomic analysis showed that both KD and A. muciniphila–and Parabacteroides-fed mice had an increased ratio of γ-aminobutyric acid (an inhibitory neurotransmitter) to glutamate (an excitatory neurotransmitter associated with seizure activity when in excess), specifically in the hippocampus, a brain region strongly associated with the propagation of seizures.

Look at Mofro, all smart and shit. I'm confused about what this sentence means:

Antibiotic-treated mice could have seizure protection restored by feeding with A. muciniphila and Parabecteroides, but not with either bacteria alone or with other bacteria.

The mice were "germ-free and without a microbiota" so does that mean that this only works (or, perhaps, seems to work) if those are the only two bacteria present? Just wondering.

That's Doctor Mofro to us cretins.

The Antibiotics kill all of the bacteria in the interstinal flora, which then makes the mice have seizures, but if the mice are fed a combo of the 2 bacteria, they are protected from the seizure phenotype again. The researchers were able to accomplish this 2 ways- 1) just by feeding the mice a keto diet, they naturally increase the % of both types of beneficial bacteria- in the context of a natural bacterial flora; and 2) then by transplanting in the bacteria into "germ free" mice to show that it is actually the bacteria themselves (not directly the diet) that reduce the seizures. More specifically, either bacterial species alone did not provide the effect, but the combo of these 2 specific bacteria did.

NASA’s Parker Solar Probe is on its way for a rendezvous with the Sun. A United Launch Alliance Delta IV Heavy rocket, carrying the spacecraft, lifted off at 3:31 a.m. EDT, from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida, its engines blazing golden in the clear night sky during ascent.
