Women’s History: Making a Better Future

Women’s History: Making A Better Future

By Cate Rees-Hessel & Wes Hessel

 

History In The Making

As Women’s History Month heads toward it’s close, we look to the theme for 2026: “Leading the Change: Women Shaping a Sustainable Future,” highlighting women who work towards sustainable improvement in economics, environment, and society. Hand in hand is the International Women’s Day (March 8th, now celebrated for 115 years) theme for this year: “Give To Gain,” reminding us that sharing multiplies time, talents, and treasure for all.

Women In Front, Push Back

Mark Twain is quoted as saying, “Behind every successful man, there is a woman.”  Behind every successful woman is one or more women who succeeded before them, breaking ground and building up new progress. Right now arch-conservatives are trying to roll back women’s rights decades, if not centuries – we need to remind all that every human is here and worthy because of at least one woman, and likely countless more. And the advancements made by women are deeper and broader than one may think. For instance, most of us know of Madame Curie, and her ground-breaking radiation work. But what about Tabitha Babbitt, a Shaker who came up with the prototype for the circular saw? Or Nancy Johnson, who patented the original hand-cranked ice cream freezer?

Intrepid Inventors

Josephine Cochrane created the first dishwasher to achieve commercial success, with the first use of water pressure to scrub. Sarah Boone improved the portable ironing board to the familiar wedge shape of what we use today for our pressing engagements. Alice H. Parker created the first natural gas central furnace.

Men Don’t Have A Monopoly

Elizabeth Magie gave us “The Landlord’s Game,” the forerunner of what we now know as probably the most recognized board game ever, “Monopoly.” In its design she made social commentary on property owners of her time in their treatment of tenants and materialistic priorities, as well as the benefits of home ownership.

Science This!

The first female scientist hired by GE, Katharine Burr Blodgett, developed the first method to put one-molecule thick coatings onto glass or metal, making possible non-reflective glass, which is used for lenses on common items such as eyeglasses, cameras, microscopes, and other optics, as well as picture frames and the like. She also invented screens during World War II to protect troops from toxins in smoke.

Even More Data

In 1944, data processing pioneer Grace Hopper worked with Howard Aiken to create the Mark I computer at Harvard, then later came up with the computer slang “bug” and its companion, “debug”, after finding an errant moth had caused a system problem; she was also on the team that developed COBOL. Architect Eleanor Raymond collaborated with biophysicist Maria Telkes to build the first home heated by solar power in 1947.

She Didn’t Just Play A Spy…

Hedy Lamarr didn’t rest on her acting laurels – her work with George Anthiel in 1941 created a “Secret Communication System” that depended at least in part on frequency-hopping for security. Initially created to make torpedoes less vulnerable to jamming, these innovations and further work on her part gave us the beginnings of “spread-spectrum” technology, which became the basis for fax machines, cell phones, GPS, Wifi, and other related wireless communication advances.

Create Like It’s 1966

1966 was a bellwether year – in it Marie Van Brittan Brown came up with and patented the first closed-circuit TV security system, and also during it Stephanie Kwolek invented one of the most important synthetic fabric fibers there is – Kevlar. She created it in the process of working on strengthening material for auto tires, which it is used for, as well as brake shoe linings, boat hulls, flame-resistant clothing, and other composite materials. But its most well-known use is something countless law enforcement and military personnel are thankful for – the bulletproof vest.

Dr. Jackson, Dr. Jackson…

The first black woman to receive a M.I.T. PhD, Shirley Jackson, helped develop modern communication technologies such as touch tones, call waiting and caller ID, and fiber optic cables, in addition to solar cells. And she was the first woman to head one of the major technological institutions, in her case Rensselaer Polytechnic Institute.

They Figure In

Since this is about women in history, we cannot bypass the great figures of the ages. Explorer Sacagawea, original First Lady Dolley Madison, abolitionist Sojourner Truth, women’s suffrage advocate Susan B. Anthony, famed authors Louisa May Alcott and Harriet Beecher Stowe, Red Cross founder Clara Barton and fellow super-nurse Florence Nightingale, aviatrix Bessie Coleman and Amelia Earhart, poet and author Julia Ward Howe, civil rights activists Rosa Parks and Coretta Scott King, just to name but a very few…

Wells, Wells, Wells…

Women typically have to be multi-taskers – many took this to levels of great feats. Ida B. Wells was a women’s rights and civil rights activist (one of the founders of the NAACP), while also wearing the hats of teacher and investigative reporter, particularly focused on the horrors of lynchings. She, working with Frederick Douglass and other African-American leaders, orchestrated a boycott of the 1893 Columbian Exposition, since Blacks were not permitted to enter the exhibit areas. Ms. Wells also advocated for school integration, and helped found many African-American clubs, particularly for women of color.

Working It In

Contemporary to Ida B. was housing reformer, women’s suffragette, social work pioneer, and political administrator Jane Addams. Harriet Tubman made a career out of multiple jobs – in addition to her famous slavery freedom trips, she was a spy for the Union, an abolitionist, and a political advocate.

Multi-mavens

Multiple talents aren’t just a precedent of years gone by – what about actress, director, and producer Penny Marshall? Or dancer, choreographer, singer, and reality talent judge Paula Abdul? Queen Latifah handles music (including songwriting), acting, and producing equally well.  You don’t have to be too swift to know the name Taylor (Swift or Dayne). While we’re on the subject of entertainment, we can’t forget Cher and Madonna. Then there’s the lifestyle mavens such as Martha Stewart, Rachel Ray, and Ree Drummond. And, of course, there’s one lady we only need one word for: Oprah.

Sporting It

Great women of sports also abound. Mildred Ella “Babe” Didrikson Zaharias excelled in baseball, golf, track and field, and basketball. In the 1932 Summer Olympics, she received two gold medals for track and field events, then became a golf professional, and went on to win ten LPGA major championships. In 1951 she was inducted into the World Golf Hall of Fame, and she was married until her death in 1956 to George Zaharias. Babe is seen as a lady ahead of her time.

They Have the Drive

Ms. Zaharias has been followed by other outstanding female athletes, such as Swedish professional lady golfer, Annika Sörenstam. She has received numerous awards, including H.M. The King’s Medal, AP Female Athlete of the Year 2003-2004, Bob Jones Award, and the Presidential Medal of Freedom. And who could forget Nancy Lopez’ precedent setting career.

Tennis Anyone?

The tennis dynasty of the Williams’ sisters is one of near domination of a particular sport. And before them was the legendary Billie Jean King, who even beat out Bobby Riggs in the much watched “Battle of the Sexes,” in 1973.

Do Something…

We can continue to commemorate women’s history in various ways:

  1. Involve yourself with female supporting groups that empower girls and women
  2. Create a brand-new book or movie club on-line, or join an existing one
  3. Treat a special lady that you receive inspiration and friendship from to a mocha latte, lunch, or bouquet of flowers
  4. Invite female entertainers, speakers, writers, and other professionals to online events
  5. Utilize all social media outlets to encourage women
  6. Utilize intersectionality to understand women of all walks of life
  7. Take an online class that enlightens women’s history
  8. Help involve children and teens in art, writing, performing, and reading women’s history related material
  9. Support STEM/STEAM initiatives targeted at encouraging young women in science and creative pursuits
  • Write a play, article, song, book, or poem about women, or read one

Color Purple And White

Let’s all wear purple, the international color which symbolizes women, and white, which represents women’s suffrage, to highlight those ladies who have contributed and continue to do so. We will keep using our voices for the advancement of female equality.

Opinion: Ditch Empathy…Ditch Democracy

OPINION: Ditch Empathy–Ditch Democracy

OPINION: Ditch Empathy–Ditch Dem0cracy

By Vajra Ma

 

Waggy is Adorable

Have you seen the ads for the new toy that looks and acts “just like a real puppy”​? Waggy is a curly haired AI puppy who tilts its adorable head just like a real dog. Waggy responds to your child’s voice just like a real dog. Sit! It sits. Come! It comes. It cuddles with your child just like a real dog. But it’s not real and according to the ad that’s the selling point. No expensive vet bills, no food to purchase, no long dog walks. No bothersome biological needs whatsoever. No care required.

No Empathy Required

What does such a realistic-seeming virtual puppy teach your child? It teaches them the puppy has no needs, no desires, no life of its own. It exists only to serve the needs and desires of your child.  The only thing that matters is the child, what he feels, what he needs, what he wants. No care or empathy required.

Biological Reality

Waggy weans your child away from biological reality. When biology is canceled, the opportunity to develop empathy for another living being is canceled.  We place our child in a subtle training ground for three things: 1) dissociation from the body 2) the atrophy 0f empathy 3) the development of narcissism. The interaction between the child and the AI dog is narcissistic. It is devoid of any feeling or even thought of the needs of another. Interaction with a virtual being is preferable to interaction with a real being.

Conditioning 

Is this what you want for your child? Is your convenience as a parent worth this programming of your child? Is this the conditioning you want for the next generation?

Toys Matter

Am I being hyperbolic? overstating the situation? I think not. Not when viewed in the context of three things: rapidly progressing AI, the transhumanist agenda and fascism. (Now she’s really getting hyperbolic!) Bear with me… There are plenty of dots to connect between these three things that could easily fill a whole book, but in the scope of this article I can only point briefly to them. Hopefully this will indicate how subtle and insidious the Waggy programming is, why a little toy like this matters.

Ditch Empathy

Elon Musk has stated “The fundamental weakness of Western civilization is empathy.” Remember him prancing about on the stage with his chainsaw? He wielded the perfect tool to represent the lack of empathy it took to slash through people’s livelihoods in his DOGE purge. Musk justifies such actions as protecting us from “civilizational suicidal empathy.” Should we prefer homicidal empathy?

Peter Thiel

In alignment with Musk, his former PayPal co-founder and kingpin of transhumanism, Peter Thiel, rejects “abstract universalism that treats all individuals as fundamentally equal.” Ditch equality, ditch democracy. Enter fascism. This brings us to the new catch phrase of the Christian Nationalist agenda…

“Toxic Empathy”

Christian author Allie Beth Stuckey, titled her book with this now popular term she coined, Toxic Empathy. In a video interview she tells us how much she likes Steven Miller and his deportations. When the interviewer pushes back about sending deportees to El Salvador (and it’s notoriously brutal CECOT prison) she deflects: (the liberals are) highlighting these stories of supposed cruelty from ICE” and admonishes people to ask “but is this true?” True? Has she seen any of the numerous videos documenting the blatant cruelty?  or does she only watch Fox News which deceives largely through omission? (emphasis added) https://www.tiktok.com/@nytopinion/video/7529126187717692703

Transhumanism

Transhumanism, at best, aims to cybor biology, at worst, to eradicate it all together in favor of uploading one’s consciousness into a computer. Either way, AI Waggy aligns and enables this.

Is that what we want for our children? or will we let ourselves see the connections between the dots?

Do we see how subtle conditioning via a cute AI toy disassociates us from biological reality? How it desensitizes us to the living needs of others? How it eradicates empathy? How it paves the way to dehumanizing others? Hitler had the Jews. We have the immigrants.

Waggy, Inside

If that’s what we want for our children, our country and the future of humanity, by all means bring (supposedly) harmless Waggy into the house. Let virtual interaction groom our children for the non-empathic narcissism and de-humanization that fascism requires. Waggy, in his adorable little robot way, helps us get there.

Shredding Documents

Does It Really Matter?

Does It Really Matter? 

D. S. Mitchell

 

I was sitting in the doctor’s office reading an old Reader’s Digest article that offered advice on when and what to shred.  According to the 6 year old article our greatest danger is through ‘mass hackings’ of our credit information. No matter how cautious we are our greatest danger is as victims of other people’s carelessness, or bad intent.  Despite that, supposedly we should still take every precaution when dealing with the disposal of sensitive documents in an effort to keep our private information private.

Does any of this really make a difference? I don’t know. I feel like my entire life has already been reduced to 0’s and 1’s; especially since DOGE scoured the federal computers for every snippet of my life story. I think I’m like a lot of Americans. Not only am I feeling vulnerable, but I feel totally betrayed by Elon Musk, Donald Trump, the Supreme Court, in other words, by own government. Will the results of such personal intrusions just mean my spam increases or will it be more serious, leading to fraudulent bank loans and other nefarious activities.

With those opposing thoughts in mind here are the suggestions from the Reader’s Digest article:

Receipts: If you aren’t saving the receipt for taxes or other purposes and you made your purchase with a credit or debit card shred it. The receipt shows the last 4 digits of the card number and possibly your signature. Those clever crooks can use receipts for fraudulent returns and benefit from your store credit.

Prescription Labels: Sometimes they are stapled to the prescription bag or on the bottle. Labels frequently list your name, date of dispensing, name and strength of the drug and dispensing pharmacy.  Crooks can use the information to refill prescriptions or steal your identity.

Pet Medical Documents: Keep records of major events for the pets health history, but shred the rest.  The paperwork will show your name, address, phone and the pet’s name, which according to many studies to be the most common computer password choices.

Airline Boarding Passes: Shred after landing. The boarding pass will show your name, your itinerary, and a bar code that in some cases will show your frequent flier number, which would allow thieves to “log in to airline accounts to view upcoming travel plans, check in to flights, and even cancel trips.”

Return Labels: Shred free return labels that come in the mail and any envelopes showing your name and address. When writing a return address on an envelope omit your name. Identity thieves will use that information to collect more information from social media and piece together your identity.

Liberals & Conservatives ARE Wired Different

The brains of conservatives and liberals are different

Liberals & Conservatives ARE Wired Different

By  Karen Tate

Observed Experience

Who hasn’t confided to their most trusted friends their amazement at how different some people are in terms of what seems to be clearly black and white issues:  Truth vs Misinformation, Democracy vs. Authoritarianism, Science vs Lack of Knowledge, Domination vs Partnership, Equality vs Inequality, Patriarchy vs Egalitarianism, Cruelty vs Compassion, Critical Thinking and NOT.  Well, it turns out there is some science behind our general differences, but we have to realize there are exceptions to the ideas compiled in this writing about liberal and conservative brain construction and thinking styles.  What’s being presented is group differences, not individual differences so this isn’t absolute, but I think you’ll find this concurs with much of what you’ve probably observed and experienced.

Meaningful and Non-Threatening

And I’ll jump to one important final conclusion before we dive in:  Each side is going to have to recognize that not everyone thinks like them, processes information like them or values the same types of things because of their brain structure and thinking style.  This is important as we move forward and attempt to find common ground because we want to be able to share information so that it comes across in a meaningful and non-threatening way. We have to be able to listen and hear each other.

Does Size Matter?

So, it turns out there are physical differences in the brains of liberals and conservatives.  Studies have shown liberals have more gray matter in their anterior cingulated cortex (ACC) and they have a smaller amygdala. Conservatives have a larger amygdala.  Why is this important?  It means the two groups process facts and ideas differently. For instance, during a study of risk-taking behavior, it was found that Democrats showed significantly greater activity in the left insula, while Republicans showed significantly greater activity in the right amygdala. Similarly, it was found that greater liberalism was associated with increased gray matter volume in the anterior cingulate cortex, whereas greater conservatism was associated with increased volume of the right amygdala.

Processing Facts

Translated into non-brain structure talk:  The psychological studies document differences in how liberals and conservatives process facts, interpret situations, feel fear and disgust, and even how well they sleep. Conservatives are less likely than liberals to be able to distinguish between facts and falsehoods, while also apportioning a similar amount of legitimacy to scientific and non-scientific viewpoints. Liberals show greater cognitive flexibility than conservatives, think more analytically, and use more effortful and deliberate reasoning, meaning they can more easily adapt to a changing situation and are more tolerant of ambiguity. Conservatives are more risk-averse than liberals and are more likely to respond to, and remember, negative stimuli.

Joe Did, Trump Did . .

Joe Did, Trump Did…

Joe Biden vs Donald Trump

 

 

Joe Did, Trump Did . . .

 

By Cate Rees-Hessel

 

Although I have made my position known on President Biden remarking, “Welcome home”, to Donald Trump, I don’t like it at all that Joe said that during Trump’s travesty of an inauguration. I feel strongly that you never say, “Welcome home”, to a traitor. I still have the utmost respect for Joe, and will always love him. “Welcome home” is a term of endearment and the comment I do feel was inappropriate to say the least, but despite the faux pas Biden will go down in history as one of our greatest presidents.

I can agree to disagree with those I care about on most subjects but “The Donald” is a bone of contention with me, not to mention the majority of his followers can not be reasoned with. Having made my position clear, please allow me to point out the extreme differences between President Biden and “The Donald”. As my husband would say, the difference between the two is like day and nightmare…

  1.  President Biden makes me smile. Trump makes we cry, shake my head in wonder, and at times laugh at his stupidity, because Dumpty has made America the laughing stock of the world.
  2. Joe Biden’s administration gave seniors insulin for $35; Trump took it away immediately after taking office.
  3. President Biden gave confidence to a young boy that stutters, showing compassion, and giving the youth his private phone number. Trump maliciously made fun of a disabled journalist and suggested his own disabled nephew “should be left to die.”
  4. Joe gave us our first female VP; Trump grabs them “by the p____”.
  5. Biden is responsible for the Violence Against Women Act; Trump has used violence against women.
  6. President Joe pardoned his son; “The Donald” pardoned those that participated in his insurrection.
  7. Joe prayed during his inauguration; Trump held a Bible upside down outside of a church he does not attend, then scribbled on God’s Word, selling made in China versions of the Good Book for $60, claiming every household should have a Bible. I agree that everyone needs access to God’s Word but if you can’t afford sixty bucks, you still deserve a Bible. Take note that the orange haired monster never said everyone should read the Bible – he admits he does not read books.
  8. Biden has not had any marital scandals; “The Donald” has committed adultery on many occasions and brags about it.
  9. Joe brought us beautiful Dr. Biden, an educated and beautiful First Lady of dignity and class; Trump brought us the only first “lady” with a staple in her navel and a history of naked pictures in cheap slut magazines.
  10. Joe built bridges with a much needed infrastructure plan; Donald continues to tout his unfinished racist wall.
  11. Joe Biden gave President Carter’s eulogy; Trump refused to allow flags at half-mast for Jimmy.
  12. Biden brought two adorable dogs and a cat to the White House; Champ and Major. Trump promoted trophy hunting and poked fun at pet owners.
  13. Joe Biden honored MLK, the man synonymous with peace; Trump is an avowed racist and violence supporter.
  14. President Biden wanted a path to citizenship for dreamers; Trump began mass deportation the first day back in office.
  15. Joe created jobs and unemployment was down in record numbers; the orange haired monster has already caused migrant workers to not show up for work.
  16. President Biden ended the pandemic, got us vaccines, reopened the economy, and gave the largest amount of stimulus. He rehired Dr. Fauci and now COVID is much less frightening and treatable. Trump refused to acknowledge or utilize the pandemic National Security Counsel Directorate for Global Health and Security and bio defense plan that the dishonest Mitch McConnell is trying to deny the existence of that the Obama administration put in place. Because of Trump millions died from COVID, not to mention many people have long term effects from the virus, and our economy is still suffering the effects of the pandemic.
  17. Biden works to end war and negotiates the safe return of hostages; the orange haired devil thrives on violence in any and every form.
  18. Joe and the Obama administration brought about much needed healthcare reform, providing insurance to millions; “The Donald” wants to end Medicaid, Medicare, and Social Security- the life line for the middle and working classes. Medicaid pays for nearly all nursing home care for seniors AND on the other end of the scale and half of the births in the United States.
  19. President Biden is a champion for safe gun laws; Trump has the NRA in his pocket (or maybe vice versa…).
  20. Joe Biden signed into law the Social Security Fairness Act, protecting the money that teachers and first responders paid into the SSA. This legislation was originally proposed all the way back in September of 2022 – Biden got it done. Trump wants to rob seniors and the disabled of their funds. Joe Biden shows respect for the LGBTQ community; Trump on day one of his second term attacked trans individuals’ rights. amongst others.
  21. President Biden is a law abiding attorney; “The Donald” is convicted felon that belongs nowhere near the Oval Office. He should not be allowed to take so much as a White House tour – Trump belongs behind bars.
  22. Biden was never impeached; Trumpty Dumpty has the unique distinction of being impeached twice…so far.
  23. Joe fights racism and anti-Semitism, and has been doing so for decades; Trump is completely anti-Semetic and a racist to everyone that is not a rich white arch-conservative male.
  24. President Biden went into action immediately to control the recent wildfires that have wrecked havoc in southern California. Trump thinks windmills cause cancer and that global warming is a hoax. Science saves lives, let’s not forget it.

I plan on writing more about Trump’s atrocious mishandling of everything he touches and more about President Biden’s years of public service. I have just begun to resist…

Paying For Purchases With Your Phone

Paying For Purchases With Your Phone

Paying by mobile app is becoming increasingly popular.

Paying For Purchases With Your Phone 

 

By D.S. Mitchell

 

Fumbling About

I was holding up the grocery store check out line while I anxiously dug around the bottom of my purse for my debit card. I was getting worried. Could I have lost the damn thing? While I tried to remember when I last used the card, I looked up and realized the guy directly behind me was rhythmically tapping his foot on the vinyl flooring. I gave him a weak smile and a whispered, “I’m sorry,” just as my fingers touched the cold plastic of the card. After paying for my purchases, I corralled everything and headed to the exit. As I passed the last row of cashiers I saw a young lady hold her cell phone in front of the payment terminal and wave it a couple time. I decided, right then and there, that when I got home I would go on the internet and find out about payment apps for my phone.

What I Found Out

As I suspected there is a lot of information on contactless payment systems, such as ‘digital wallet’. Mobile payment apps are growing increasingly popular. Apparently nearly 85% of Americans own smartphones and the benefits provided by such payment systems are more and more evident. Here are a few of the benefits I learned about.

  1. Convenience: No more digging around your purse for your debit card or cash. Just take out your phone and open the digital wallet app and wave or tap your phone near the payment terminal. Easy peasy.
  2. Security: A mobile payment app has security advantages unavailable with other payment methods. First, and most obviously, you don’t need to carry cash or credit cards, which are always at risk of being lost or stolen. Second, the mobile payment apps have layers of extra security to protect user data, like encrypting personal information, plus there is a layer of biometric authentication such as fingerprint and facial recognition. Lastly, each transaction involves a one time code or token. The token is used to complete the transaction in place of the buyer’s actual personal information. The code is for a one time only use. That token cannot be reused and is effectively useless if hacked.
  3. Speed: It’s super fast, just a one-two-three tap to pay. Plus there’s a budget and expense tracking feature. If you happen to have a money management app it can be easily integrated with the digital wallet app. Every transaction is instantly recorded for future reference and review.
  4. Safety: Since COVID-19 hit everyone is a bit more concerned about germs on surfaces and in the air. Mobile apps enable the consumer to complete their purchases without handling germ infected cash or touching germ infected credit card terminals.

Setting It Up

Here’s how to set up your contactless payment system.

  1. Get your phone and find the pre-installed payment app on the screen. It will be Apple Wallet for iphones or GPay for Android devices.
  2. Tap on the icon, Apple Pay or the $ icon, then enter credit or debit card information into the fields. You can add multiple cards and select a default for the card used most frequently.
  3. When you want to make a purchase, launch the app (select card preference if you did not select default), hold your smart phone or smartwatch close to the merchant’s card terminal.
  4. You will be asked to confirm the purchase. If you are using a debit card for payment, you may be asked your pin number.

I did it, it’s all set up. Now, my next challenge is remembering to use the damn thing.

Happy 2024.

Transplant Patients Get New Hope

New Hope For Transplant Patients

In a history making surgery and an amazing 61 days a pig kidney works normally inside a donated cadaver, raising hope for animal to human transplants

Pig Kidney Offers Hope For Dying Patients

A brain dead patient receives a pig’s kidney 

By D. S. Mitchell 

 

OHSU Transplant

As a young RN I worked at University Hospital, in Portland, Oregon. My first assignment was on the Transplant floor. Although it was many years ago, now, it was a great experience, helping those who would die without a donated organ. At that time we did kidney, liver, pancreas, and hearts. It is an amazing program extending life for 1,000’s of patients over the years. One of the hardest things for patient is the seemingly interminable wait if they don’t have a genetic match with a potential family donor. At least a 100,000  people are on the national waiting list, the majority need a kidney, and sadly thousands will die waiting for a donor.

New Hope On The Way

A history making experiment has been underway for the last two months in a New York hospital that offers promise to those waiting for a kidney donation. Xenotransplantation has for decades been nothing more than a dream. The problem is the human immune system, which immediately goes to work to kill the foreign animal tissue. With a new approach scientists are working with genetically modified pigs, so the pigs organs are more humanlike. Some research teams insist on pigs that have up to 10 genetic changes.  The transplant team led by Dr. Robert Montgomery, a heart transplant recipient himself, used in this study, is a pig kidney with only one genetic modification. Importantly, the single gene modification is the removal of a gene that triggers an immediate immune attack.

Maurice “Mo” Miller 

The human recipient, Maurice “Mo” Miller, had collapsed and was declared brain-dead, his family was unable to donate his organs because of cancer. His sister after much consideration chose to donate the the man’s body to the pig experiment. Dr. Montgomery gambled that he could keep Miller’s body on a ventilator for two months to test the transplanted pig kidney. On July 14, 2023, surgeons replaced Miller’s two kidneys with one pig kidney and the pig’s thymus. The thymus is a gland that “trains” immune cells. Two months later at the termination of the experiment, Miller was taken off the ventilator and prepared for cremation. The kidney was still performing perfectly.

The Future

The information gained from this study will be provided to the FDA in the hopes that xenotransplantation may soon be attempted on living humans. Experiments on the dead cannot be predictors of organ transplant success with living subjects. I see years of testing, but this amazing case gives us all hope that someday we will be able to transplant modified animal organs into living humans, saving lives, that would have ended too soon.

VACCINE BASICS

The strength of the anti-vaxxer movement in the U.S. is dangerous to the public health.

Vaccine Basics: The Truth About Vaccines

The Chinese were using inoculation over a 1,000 years ago in an attempt to protect people from the scourge of small pox. Those early physicians would make a scratch on a person’s arm or leg and then rub fluid from the pox pustules into the broken skin. Another method involved blowing infected dust from scabs into the nostrils of a healthy individual. The first record of an injection of a weakened form of small pox was by a British physician, Edward Jenner, in the 18th century.

An Army

Any regular reader of this website knows that I am a retired RN. And as such, health and wellness issues are an important part of the information I share on this site. The COVID-19 pandemic brought out an army of anti-vaxxers, led by a-holes like RFK, Jr. There’s a guy despised by his family and recognized world wide as a “nut cake,” but even someone as despised and discredited as Kennedy has followers. Just because his dad was famous and cool does not mean he passed any of that charisma, intellect, or personality on to his children, particularly junior, in this case.

A Veritable Quandary

I don’t understand it. During my life time vaccines have nearly caused us to forget the severe outbreaks of “childhood diseases” including polio, tetanus, hepatitis A and B, rubella, mumps, whooping cough, rotavirus, smallpox, measles, and more. Vaccines save money. If you don’t care about the human cost, there is the financial cost of infectious diseases on our country. The CDC estimates that inoculation against measles has saved the United States $295 billion in hospital costs and $1.4 trillion in societal costs over a 15 year span, according to an article in the August 2020  Prevention magazine, by Jennifer Wolff

Whatever

Fear, misinformation, and superstition are all drivers of the anti-vax movement. Because of all the screaming and hollering and the threats against Dr. Fauci, I thought now might be as good a time as any to provide a short refresher course on what vaccines are and what they are not.

The Truth Behind The Hydrogen Hype

Is hydrogen really a zero carbon fuel that we dream of?

The Truth Behind The Hydrogen Hype

Hydrogen is being touted as the fuel of the future, but new information suggests hydrogen could have serious implications for the climate. 

By D.S. Mitchell

Maybe Not The Golden Ticket

As the hydrogen hype machine revs up to a roar, investigators are discovering potential, undisclosed  hazards to the climate. Scientists are warning that hydrogen is not the golden ticket to stabilize the earth’s climate that supporters claim. One big problem is that hydrogen leaks and those leaks are harmful to the environment.

EDF’s Solutions Magazine Vol.54 No.2/Spring 2023

Hydrogen’s promise as a climate solution has fascinated Hollywood screenwriters, entrepreneurs, scientists, and governments, including China, India, the U.S. and EU for decades. According to McKinsey  & Co. investment in hydrogen manufacture is coming fast and furious as governments and individuals embrace hydrogen. Over the next decade 680  large scale hydrogen projects will be commenced worldwide at a projected cost of $240 billion.

Zero Carbon? Yes and No.

When hydrogen is burned or used in a fuel cell it produces zero carbon emissions. Wha-hoo, that fact is why hydrogen has become the holy grail of climate friendly energy. But as with all things, not so fast. Pure hydrogen is rarely found in nature. Because of that, hydrogen must be EXTRACTED from another source. Today nearly all hydrogen is extracted from coal and natural gas and that process releases carbon dioxide into the environment. Damn, that doesn’t sound good and it isn’t good. Investigators claim if “hydrogen production were a country it would rank as the world’s fourth largest source of carbon dioxide.” Staggering numbers when the small amount of hydrogen being produced is taken into consideration.

Green Hydrogen

Green hydrogen can be produced from water, using renewable energy. Unfortunately, less than 1% of hydrogen production is green. But, even green hydrogen isn’t harmless. When burned hydrogen creates nitrous oxides. Those pollutants can cause asthma, bronchitis, and heart disease. Furthermore,  hydrogen is leak prone with a potent climate warming effect that is not talked about, but needs to be addressed. As  EDF scientist, Ilissa Ocko said, “If hydrogen is going to deliver what its backers promise, we need to keep it from escaping (leaking) into the atmosphere.”

A Fully Hydrogen Powered World is Unlikely

Currently, hydrogen is used primarily in oil refining and the chemical industry. Otherwise, hydrogen use is on a very small scale in buses, cars, trucks, trains, and homes.  Ocko believes a fully hydrogen powered world is “unlikely and unnecessary.” In most cases renewable electricity is a more efficient choice. If hydrogen isn’t going to be universal where does its production make the most sense? The experts say it makes the most sense in heat-intensive industries, such as cement production, or in ships where electrification is difficult.

Keep ‘Em Close

Scientists are recommending the manufacture of hydrogen be close to where it will be used. It is important to minimize leaks during transportation. Experts agree that a hydrogen system that’s as leaky as the current natural gas system could lead to major problems for the environment and the climate. Locating, measuring, and sealing hydrogen leaks is a critical issue that will need to be solved.

How Dangerous Are Hydrogen Leaks

Hydrogen leaks are a safety hazard because hydrogen gas molecules are tiny and flammable.  Because hydrogen is an indirect greenhouse gas when it leaks it creates a chain of chemical reactions that raise levels of greenhouse gases in our atmosphere. Small hydrogen leaks are serious because they exacerbate global warming. Finding those small leaks, until recently was impossible. Today however a new sensor is showing success. By detecting tens of parts per billion of hydrogen within seconds, the sensor represents a technological breakthrough in hydrogen emissions detection. Tianyl Sun, an EDF scientist says, “right now we know very, very little about how much hydrogen leaks. Filling that gap in our understanding is critically important for the climate.”

The Future of Hydrogen

The future of hydrogen is up in the air. Hydrogen can be a key tool to cut climate pollution, but its dangers may outweigh its positives. As with most things, time will tell.
