Plasma Propulsion finally goes mainstream for space and jet travel

 Plasma jet engines are being tested for air transportation using electricity to ionize ambient air instead of burning fossil fuels....

see my new playlist for details! I discussed this in my 2012 book so I just searched for an update. Sure enough - it's not considered the best means of "clean" transportation and also "sustainable" for long-distance space travel. The propulsion fuel is extracted from the ether! 

Alcohol irritates and damages the bladder!

 

Yes, alcohol directly affects your bladder by increasing urine production, irritating the bladder lining, and disrupting normal muscle control. [1, 2, 3]
How Alcohol Affects the Bladder
  • More urine: Alcohol stops your body from making vasopressin. This is a hormone that tells your kidneys to save water. Without it, your kidneys make extra urine and your bladder fills up fast. [1, 2]
  • Bladder irritation: Alcohol can inflame and irritate the lining of your bladder. This irritation causes sudden or frequent urges to go to the bathroom. [1, 2]
  • Muscle disruption: Alcohol interferes with the nerves and muscles that help you control when you urinate. This can lead to overactivity, leaks, or trouble controlling your bladder. [1]
  • Dehydration: Drinking alcohol causes water loss. This makes your urine more concentrated, which further irritates the bladder lining. [1, 2]
  • Infection risk: Alcohol can weaken your immune system, making it harder for your body to fight off urinary tract infections (UTIs

Top British Ale in Minnesota: Old Crown by Sunken Ship craft brewery

 Just got back from a road trip! I listened to the author of "Beer Invented Civilization" - a professor and master brewer scientist. He says a British ale is the BEST BEER. So I searched - Minnesota doesn't sell a British Ale unless you go to Brit's Pub, downtown Minneapolis, for an import. So I found the "top beer of 2025" is a British Ale for Minnesota Craft Beers! I took my mom on a road trip! She admitted the beer tastes really good. It's a seriously very tasty beer and not very high in alcohol. One 25 ounce KING beer and I'm buzzed but not that buzzed. A nice relaxing buzz. thanks.

Dr. Charlie Bamforth, often nicknamed the "Pope of Foam," is a renowned brewing scientist and Distinguished Professor Emeritus of Malting and Brewing Sciences at the University of California, Davis. [1, 2, 3]
The "Pope of Foam" and Civilization
  • The Moniker: Dr. Bamforth earned the title "Pope of Foam" due to his extensive research into the science, creation, and stability of foam (the head) on top of a beer. [1]
  • Beer and Civilization: He is a prominent proponent of the theory that beer is the basis of modern static civilization. [1]
  • The Theory: He frequently explains in lectures and media appearances (such as NPR and his talk "Sip Happens: The Science and Story of Beer") that early nomadic hunter-gatherers stopped wandering and settled down to cultivate grains like barley specifically to brew beer, which led to permanent villages, towns, and eventually modern cities. [1, 2, 3]
Would you like to know more about Dr. Bamforth's research on beer foam physics or the "beer before bread" archaeological theory he discusses?

OfficeMax has Kafkaesque Rewards Program for recycling print cartridges

 If you return your print cartridges you HAVE to spend $10 to get the $2 per cartridge but you do not get the $2 per cartridge until 24 hours after you spend the $10. So if you return your print cartridges "early" it doesn't matter - you have to spend $10 minimum to then be able to use the rebate and the rebate is only good for two months. So you are FORCED to make two trips back to OfficeMax no matter what - no way around it. Once to qualify and once to use it. 

 up to a limit of 10 cartridges per calendar month

 Rewards certificates issued for recycling print cartridges at Office Depot / OfficeMax are valid for 60 days from the date they are issued

Office Depot and OfficeMax Rewards post recycling rewards to your account the next day after you recycle your cartridges and meet the $10 qualifying purchase requirement for that month. [1, 2]
Recycling Rewards Details
  • Payout Timing: Rewards appear the next day online once the $10 qualifying purchase is satisfied.
  • Monthly Limit: You can earn $2 back per recycled cartridge, up to 10 cartridges per month.
  • Qualifying Purchase: You must make a $10 minimum purchase in the same calendar month to unlock the credit. If you recycle first, the reward stays on hold until you complete the $10 purchase
  • Staples? Minimum Purchase: You must spend at least $30 on ink or toner at Staples within the previous 180 days to qualify for the $2 reward per cartridge. Easy Straightforward - no need to make two trips! 
  •  

    Can you turn around and use them right away? I had a customer last week recycle ink and within 60 seconds I checked his account and the rewards were there. One of the best parts of the new Easy Rewards system...: Staples Easy Rewards members earn 500 points per cartridge recycled in-store (roughly $2.50 in value), up to 6 cartridges per month.

Over a Billion People right now have Worms: Worms take your nutrition: Walter Jahn on Homo Evolution

https://www.youtube.com/watch?v=D4uGkjZ5O9w

Fire is what enabled us to digest meat better for better nutrition and also to kill off worms in meat...

 Homo Erectus is first real fire use and spread around the world ....

 a female orgasm is not the same as male ejaculation. Bonobo females dominate as female orgasm. It's not just "sex." Female orgasm stays in the parasympathetic relaxation nervous system. Male ejaculation for bonobos only happens for mating. The females are doing it all the time to resolve stress. Male ejaculation increases stress. So that's a key point if you want to talk about Bonobos. Study the San Bushmen - the males of our original human culture train in female orgasm as spiritual healing celibacy! It's called Tshoma. Watch the "radical anthropology" lectures series on Vimeo for details. The Harmless People book by Dr. Elizabeth Marshall Thomas was rejected by Male anthropologists because of their ejaculation bias. hahaha.

Walter Jahn lectures series on Genetics! 

Wow - he's got really great lectures!

 

Fungi-produced Erythritol Is More Effective Than Xylitol and Sorbitol in Managing Oral Health Endpoints

 https://pmc.ncbi.nlm.nih.gov/articles/PMC5011233/

OK based on that study I just ordered eight pounds of organic Erythritol!!

I am finishing off my Xylitol - it has done wonders for my teeth - keeps them squeaky clean!

I'll be curious to see what the Erythritol does!

OH dang - that study is 10 years old!?

https://www.tandfonline.com/doi/pdf/10.1080/20002297.2025.2526069 

Here's a new one. 

 In the erythritol group, the lactate concentration significantly decreased com-
pared to that of the control group, whereas the pH did not significantly change. In addition, when nitrate was added in combination with xylitol or sorbitol, neither the pH nor lactate concentration significantly changed compared to those of the control group
(Figure 6a,b)....The present study suggests that the combined addition of nitrate and erythritol significantly increased the relative abundance of H. parainfluenzae and
N. subflava, which are nitrate-reducing bacteria...Notably, the combined addition of nitrate
and either xylitol or sorbitol had no significant effect on the relative abundances of H. parainfluenzae, N. subflava, and S. oralis, nor the diversity of the microbial community.... These results suggest that the combined addition of nitrate and erythritol may
promote an oral cavity environment that is less conducive to the development of dental caries.
Organic erythritol is produced through the controlled microbial fermentation of organic plant-derived glucose using natural yeasts or fungi

 

  • Sourcing Organic Feedstock: Production starts with an organic, non-GMO plant starch source—most commonly organic corn or wheat. [1, 2]
  • Enzymatic Hydrolysis: The raw organic starch is treated with water and hydrolytic enzymes to break complex carbohydrates down into simple sugars (glucose or dextrose). [1, 2]
  • Fermentation: The glucose solution acts as food for natural, non-GMO yeasts or fungi (such as Moniliella pollinis or Trichosporonoides megachiliensis). As the microorganisms digest the glucose, they naturally synthesize and release erythritol into the liquid broth
  • https://link.springer.com/content/pdf/10.1186/s12939-024-02279-0.pdf 

     Upon ingestion, erythritol is rapidly absorbed in
    the small intestine, with most excreted unchanged in the urine and a small
    portion metabolized to erythronate.4 The absorption rate is dose-
    dependent, as demonstrated in a recent trial where higher doses (50 g) re-
    sulted in slower absorption compared with lower doses (10 g, 25 g),
    suggesting a saturable process.

     While consumption
    of erythritol has no impact on plasma glucose and insulin levels, xylitol leads
    to a small increase.

     More recent studies have repeatedly demonstrated that acute erythritol
    and xylitol consumption—despite their lack in calories—trigger gastro-
    intestinal satiation hormones (incretins) release (namely cholecystokinin,
    glucagon-like peptide-1, and peptide tyrosine tyrosine), and erythritol
    has also been shown to lower concentrations of the hunger hormone
    ghrelin.

     

     

     Mendelian randomisation analyses did not find evidence for a causal
    association between circulating erythritol and coronary artery disease, dia-
    betes, fasting glucose, eGFR, or chronic kidney disease, nor was any evi-
    dence found that the evaluated cardiometabolic and anthropometric
    traits significantly influenced erythritol concentration. Rather, Mendelian
    randomisation indicated erythritol may decrease BMI

     While a significant proportion of xylitol enters the colon, erythritol is
    mostly absorbed in the small intestine.4 Moreover, erythritol, which is
    only minimally available to the colon, appears non-fermentable, as shown
    in studies with fresh human faecal microbiota.56 Overall, xylitol appears
    to have prebiotic effects, whereas erythritol likely has no impact on the
    gut microbiota.
    This study found that erythritol consumption acutely im-
    proves small vessel endothelial function (fingertip peripheral arterial tono-
    metry), and chronic treatment reduced central aortic stiffness (decreased
    central pulse pressure).59

     In humans with or without obesity, both acute erythritol and xylitol ingestion also delays gastric emptying

     The consumption of erythritol and xylitol stimulates the release of
    gastrointestinal satiation hormones while the impact on blood glucose
    and insulin concentrations remains minimal. These effects are desirable
    in the context of metabolic and CV health.

    Wireless Brain-computer Implant successfully transforms thoughts into speech

     The Connexus brain implant is a fully wireless brain-computer interface (BCI) developed by Paradromics that records brain signals from individual neurons and translates them into real-time speech or computer commands

    https://www.michiganmedicine.org/news-release/university-michigan-implants-first-human-paradromics-wireless-brain-computer-interface-designed 

    the potential of this wireless BCI to restore communication for people who have lost the ability to speak due to neurological disease or injury,” said Willsey, a Site Principal Investigator for the study who led the implant surgery.

    “This has the potential to be a major step forward as we work toward our goal of helping treat people with paralysis who otherwise lack efficient and effective therapies for preserving communication.”

     allowing the user to control a device with their thoughts.

    The Paradromics device contains 421 microelectrodes that capture brain signals from individual neurons. Those signals travel to a small transceiver in the user’s chest that sends information to an external receiver.
