As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I may have missed it, but how much black pepper provides benefits?❞
So, for any new subscribers joining us today, this is about two recent main features:
As for a daily dosage of black pepper, it varies depending on the benefit you’re looking for, but:
- 5–20mg of piperine is the dosage range used in most scientific studies we looked at
- 10mg is a very common dosage found in many popular supplements
- That’s the mass of piperine though, so if taking it as actual black pepper rather than as an extract, ½ teaspoon is considered sufficient to enjoy benefits.
❝I loved the health benefits of pepper. I do not like pepper. Where can I get it as a supplement?❞
You can simply buy whole black peppercorns and take a few with water as though they were tablets. Your stomach acid will do the rest. Black pepper is also good for digestion, so taking it with a meal is best.
You can buy piperine (black pepper extract) by itself as a supplement in powder form, but if you don’t like black pepper, you will probably not like this powder either. We couldn’t find it readily in capsule form.
You can buy piperine (black pepper extract) as an adjunct to other supplements, with perhaps the most common/popular being turmeric capsules that also contain 10mg (or more) piperine per capsule. Shop around if you like, but here’s one that has 15mg piperine* per capsule, for example.
*They call it “Bioperine®” but that is literally just piperine. Same go

Meningitis Outbreak

Don’t Let Your Guard Down
In the US, meningitis is currently enjoying a 10-year high, with its highest levels of infection since 2014.
This is a big deal, given the 10–15% fatality rate of meningitis, even with appropriate medical treatment.
But of course, not everyone gets appropriate medical treatment, especially because symptoms can become life-threatening in a matter of hours.
Most recent stats gave an 18% fatality rate for the cases with known outcomes in the last year:
CDC Emergency | Increase in Invasive Serogroup Y Meningococcal Disease in the United States
The quick facts:
❝Meningococcal disease most often presents as meningitis, with symptoms that may include fever, headache, stiff neck, nausea, vomiting, photophobia, or altered mental status.
[It can also present] as meningococcal bloodstream infection, with symptoms that may include fever and chills, fatigue, vomiting, cold hands and feet, severe aches and pains, rapid breathing, diarrhea, or, in later stages, a dark purple rash.
While initial symptoms of meningococcal disease can at first be non-specific, they worsen rapidly, and the disease can become life-threatening within hours. Immediate antibiotic treatment for meningococcal disease is critical.
Survivors may experience long-term effects such as deafness or amputations of the extremities.❞
~ Ibid.
The good news (but still don’t let your guard down)
Meningococcal bacteria are, happily, not spread as easily as cold and flu viruses.
The greatest risks come from:
- Close and enduring proximity (e.g. living together)
- Oral, or close-to-oral, contact (e.g. kissing, or coughing nearby)

Is there a vaccine?
There is, but it’s usually only offered to those most at risk, which is usually:
- Children
- Immunocompromised people, especially if HIV+
- People taking certain medications (e.g. Solaris or Ultomiris)

CDC | Meningococcal Vaccine Recommendations
Will taking immune-boosting supplements help?
Honestly, probably not, but they won’t harm either. The most important thing is: don’t rely on them—too many people pop a vitamin C supplement and then assume they are immune to everything, and it doesn’t work like that.
On a tangential note, for more general immune health, you might also want to check out:
Beyond Supplements: The Real Immune-Boosters!
The short version:
If you or someone you know experiences the above-mentioned symptoms, even if it does not seem too bad, get thee/them to a doctor, and quickly, because the (very short) clock may be ticking already.
Better safe than sorry.

Jackfruit vs Durian – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing jackfruit to durian, we picked the durian.
Why?
Durian may look and smell like it has come directly from Hell, but there’s a lot of goodness in there!
First, let’s talk macros: jackfruit and durian are both unusually high in protein, for fruits. That said, jackfruit does have slightly more protein—but durian has more than 2x the fiber, for only slightly more carbs, so we call this section a win for durian.
Like most fruits, these two are an abundance source of vitamins; jackfruit has more of vitamins A and E, while durian has more of vitamins B1, B2, B3, B9, and C. Another win for durian.
When it comes to minerals, jackfruit has more calcium, while durian has more copper, iron, manganese, phosphorus, and zinc. We don’t usually measure this one as there’s not much in most foods (unless added in artificially), but durian is also high in sulfur, specifically in “volatile sulfur compounds”, which account for some of its smell, and are—notwithstanding the alarming name—harmless. In any case, mineral content is another win for durian.
These three things add up to one big win for durian.
There is one thing to watch out for, though: durian inhibits aldehyde dehydrogenase, which the body uses to metabolize alcohol. So, we recommend you don’t drink-and-durian, as it can increase the risk of alcohol poisoning, and even if alcohol consumption is moderate, it’ll simply stay in your system for longer, doing more damage while it’s there. Of course, it is best to simply avoid drinking alcohol regardless, durian or no durian, but the above is good to know for those who do imbibe.
A final word on durians: if you haven’t had it before, or had it and it was terrible, then know: much like a banana or an avocado, durian has a rather brief “ideal ripeness” phase for eating. It should be of moderate firmness; neither tough nor squishy. It should not have discolored spikes, nor should it have little holes in, nor be leaking fluid, and it should not smell of sweat and vinegar, although it should smell like sulfurous eggs, onions, and cheese. Basically, if it smells like a cheese-and-onion omelette made in Hell, it’s probably good. If it smells like something that died and then was kept warm in someone’s armpit for a day, it’s probably not. The best way to have a good first experience with a durian is to enjoy one with someone who knows and enjoys durians, as they will be able to pick one that’s right, and will know if it’s not (durian-sellers may not necessarily have your best interests at heart, and may seek to palm off over-ripe durians on people who don’t know better).
Enjoy!

What to Know About Stillbirths
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Series: Stillbirths:When Babies Die Before Taking Their First Breath
The U.S. has not prioritized stillbirth prevention, and American parents are losing babies even as other countries make larger strides to reduce deaths late in pregnancy.
Every year, more than 20,000 pregnancies in the U.S. end in a stillbirth, the death of an expected child at 20 weeks or more of pregnancy. Research shows as many as 1 in 4 stillbirths may be preventable. We interviewed dozens of parents of stillborn children who said their health care providers did not tell them about risk factors or explain what to watch for while pregnant. They said they felt blindsided by what followed. They did not have the information needed to make critical decisions about what happened with their baby’s body, about what additional testing could have been done to help determine what caused the stillbirth, or about how to navigate the process of requesting important stillbirth documents.
This guide is meant to help fill the void of information on stillbirths. It’s based on more than 150 conversations with parents, health care providers, researchers and other medical experts.
Whether you’re trying to better prepare for a pregnancy or grieving a loss, we hope this will help you and your family. This guide does not provide medical advice. We encourage you to seek out other reliable resources and consult with providers you trust.
We welcome your thoughts and questions at mailto:stillbirth@propublica.org. You can share your experience with stillbirth with us. If you are a health care provider interested in distributing this guide, let us know if we can help.
Table of contents:
- What Is Stillbirth?
- Are Stillbirths Preventable?
- What to Expect After a Stillbirth.
- Grieving After a Stillbirth.
- What You Might Say and Do After a Loved One Experiences a Stillbirth.
What Is Stillbirth?
Many people told us that the first time they heard the term stillbirth was after they delivered their stillborn baby. In many cases, the lack of information and awareness beforehand contributed to their heartache and guilt afterward.
Stillbirth is defined in the U.S. as the death of a baby in the womb at 20 weeks or more of pregnancy. Depending on when it happens, stillbirth is considered:
- Early: 20-27 weeks of pregnancy.
- Late: 28-36 weeks of pregnancy.
- Term: 37 or more weeks of pregnancy.
About half of all stillbirths in the U.S. occur at 28 weeks or later.
What is the difference between a stillbirth and a miscarriage?
Both terms describe pregnancy loss. The distinction is when the loss occurs. A miscarriage is typically defined as a loss before the 20th week of pregnancy, while stillbirth is after that point.
How common is stillbirth?
Each year, about 1 in 175 deliveries in the U.S. are stillbirths — that’s about 60 stillborn babies every day — making it one of the most common adverse pregnancy outcomes, but it is rarely discussed.
If you are surprised by that fact, you are not alone. Many people we spoke to did not know how common stillbirths are. Leandria Lee of Texas said she spent her 2021 pregnancy unaware that her daughter, Zuri Armoni, could die in the last phase of her pregnancy.
“If I was prepared to know that something could happen, I don’t think it would have been as bad. But to not know and then it happens, it affects you,” she said of her stillbirth at 35 weeks.
Some doctors have told us they don’t introduce the possibility of a stillbirth because they don’t want to create additional anxiety for patients.
Other doctors say withholding information leaves patients unprepared.
“We have this idea that we can’t scare the patient, which to me is very paternalistic,” said Dr. Heather Florescue, an OB-GYN near Rochester, New York, who works to inform doctors and patients about stillbirth prevention.
What causes stillbirths?
There is a lot we don’t know about stillbirths because there hasn’t been enough research. The cause of the stillbirth is unknown in about 1 in 3 cases.
What we do know is that a number of factors may cause or increase the risk of a stillbirth, including:
- The baby not growing as expected.
- Placental abnormalities or problems with the umbilical cord.
- Genetic or structural disorders that cause developmental issues.
- High blood pressure before pregnancy or preeclampsia, a potentially fatal complication that usually appears late in pregnancy and causes high blood pressure.
- Diabetes before or during pregnancy.
- An infection in the fetus, the placenta or the pregnant person.
- Smoking.
- Being 35 or older.
- Obesity.
- Being pregnant with more than one baby.
But not all doctors, hospitals or health departments perform tests to identify the potential cause of a stillbirth or determine if it could have been prevented. Even when a cause is identified, fetal death records are rarely updated. This means data is sometimes inaccurate. Researchers strongly encourage doctors to perform a stillbirth evaluation, which includes an examination of the placenta and umbilical cord, a fetal autopsy and genetic testing.
If your hospital or doctor does not proactively offer one or more of these exams, you can ask them to conduct the tests. Research shows that placental exams may help establish a cause of death or exclude a suspected one in about 65% of stillbirths, while autopsies were similarly useful in more than 40% of cases.
Are Stillbirths Preventable?
Not all stillbirths are preventable, but some are. For pregnancies that last 37 weeks or more, one study found that nearly half of stillbirths are potentially preventable.
Dr. Joanne Stone, who last year was president of the Society of Maternal-Fetal Medicine, leads the country’s first Rainbow Clinic at Mount Sinai Hospital in New York. The clinic is modeled on similar facilities in the United Kingdom that care for people who want to conceive again after a stillbirth. She said many doctors used to think there was nothing they could do to prevent stillbirth.
“People just looked at it like, ‘Oh, it was an accident, couldn’t have been prevented,’” said Stone, who also is the system chair of the obstetrics, gynecology and reproductive science department at the Icahn School of Medicine. “But we know now there are things that we can do to try to prevent that from happening.”
She said doctors can:
- More closely monitor patients with certain risk factors, like high blood pressure, diabetes or obesity.
- Ask about prior infant loss or other obstetrical trauma.
- Carefully assess whether a baby’s growth is normal.
- Work to diagnose genetic anomalies.
- Teach patients how to track their baby’s movements and encourage them to speak up if they notice activity has slowed or stopped.
- Deliver at or before 39 weeks if there are concerns.
What are the risks of stillbirth over the course of a pregnancy?
The risk of a stillbirth increases significantly toward the end of pregnancy, especially after 39 weeks. The risk is higher for people who get pregnant at 35 or older. The risk begins to climb even earlier, around 36 weeks, for people pregnant with twins.
What you and your doctor can do to reduce the risk of stillbirth.
While federal agencies in the U.S. have yet to come up with a checklist that may help reduce the risk of stillbirth, the Stillbirth Centre of Research Excellence in Australia has adopted a Safer Baby Bundle that lists five recommendations:
- Stop smoking.
- Regularly monitor growth to reduce the risk of fetal growth restriction, when the fetus is not growing as expected.
- Understand the importance of acting quickly if fetal movement decreases.
- Sleep on your side after 28 weeks.
- Talk to your doctor about when to deliver. Depending on your situation, it may be before your due date.
The American College of Obstetricians and Gynecologists has compiled a list of tests and techniques doctors can use to try to reduce the risk of a stillbirth. They include:
- A risk assessment to identify prenatal needs.
- A nonstresstest, which checks the fetus’s heart rate and how it changes as the fetus moves.
- A biophysical profile, which is done with an ultrasound to measure body movement, muscle tone and breathing, along with amniotic fluid volume.
The group stressed that there is no test that can guarantee a stillbirth won’t happen and that individual circumstances should determine what tests are run.
Are some people at higher risk for stillbirth?
Black women are more than twice as likely to have a stillbirth as white women. There are a number of possible explanations for that disparity, including institutional bias and structural racism, and a patient’s pre-pregnancy health, socioeconomic status and access to health care. In addition, research shows that Black women are more likely than white women to experience multiple stressful life events while pregnant and have their concerns ignored by their health care provider. Similar racial disparities drive the country’s high rate of maternal mortality.
How to find a provider you trust.
Finding a doctor to care for you during your pregnancy can be a daunting process. Medical experts and parents suggest interviewing prospective providers before you decide on the right one.
Here is a short list of questions you might want to ask a potential OB-GYN:
- What is the best way to contact you if I have questions or concerns?
- How do you manage inquiries after hours and on weekends? Do you see walk-ins?
- How do you manage prenatal risk assessments?
- What should I know about the risks of a miscarriage or stillbirth?
- How do you decide when a patient should be induced?
If a provider doesn’t answer your questions to your satisfaction, don’t be reluctant to move on. Dr. Ashanda Saint Jean, chair of the obstetrics and gynecology department at HealthAlliance Hospitals of the Hudson Valley in New York, said she encourages her patients to find the provider that meets their needs.
“Seek out someone that is like-minded,” said Saint Jean “It doesn’t have to be that they’re the same ethnicity or the same race, but like-minded in terms of the goals of what that patient desires for their own health and prosperity.”
What to know in the last trimester.
The last trimester can be an uncomfortable and challenging time as the fetus grows and you get increasingly tired. During this critical time, your provider should talk to you about the following topics:
- Whether you need a nonstress test to determine if the fetus is getting enough oxygen.
- The best way to track fetal movements.
- What to do if your baby stops moving.
- Whether you are at risk for preeclampsia or gestational diabetes.
Rachel Foran’s child, Eoin Francis, was stillborn at 41 weeks and two days. Foran, who lives in New York, said she believes that if her doctor had tracked her placenta, and if she had understood the importance of fetal movement, she and her husband might have decided to deliver sooner.
She remembers that her son was “very active” until the day before he was stillborn.
“I would have gone in earlier if someone had told me, ‘You’re doing this because the baby could die,’” she said of tracking fetal movement. “That would have been really helpful to know.”
Researchers are looking at the best way to measure the health, blood flow and size of the placenta, but studies are still in their early stages.
“If someone had been doing that with my son’s,” Foran said, “my son would be alive.”
A placental exam and an autopsy showed that a small placenta contributed to Foran’s stillbirth.
How often should you feel movement?
Every baby and each pregnancy are different, so it is important to get to know what levels of activity are normal for you. You might feel movement around 20 weeks. You’re more likely to feel movement when you’re sitting or lying down. Paying attention to movement during the third trimester is particularly important because research shows that changes, including decreased movement or bursts of excessive activity, are associated with an increased risk of stillbirth. Most of the time, it’s nothing. But sometimes it can be a sign that your baby is in distress. If you’re worried, don’t rely on a home fetal doppler to reassure you. Reach out to your doctor.
Saint Jean offers a tip to track movement: “I still tell patients each day to lay on their left side after dinner and record how many times their baby moves, because then that will give you an idea of what’s normal for your baby,” she said.
Other groups recommend using the Count the Kicks app as a way of tracking fetal movements and establishing what is normal for that pregnancy. Although there is no scientific consensus that counting kicks can prevent stillbirths, the American College of Obstetricians and Gynecologists and other groups recommend that patients be aware of fetal movement patterns.
Dr. Karen Gibbins is a maternal-fetal medicine specialist at Oregon Health & Science University who in 2018 had stillborn son named Sebastian. She said the idea that babies don’t move as much at the end of pregnancy is a dangerous myth.
“You might hear that babies slow down at the end,” she said. “They don’t slow down. They just have a little less space. So their movements are a little different, but they should be as strong and as frequent.”
What to Expect After a Stillbirth
What might happen at the hospital?
Parents are often asked to make several important decisions while they are still reeling from the shock and devastation of their loss. It’s completely understandable if you need to take some time to consider them.
Some other things you can ask for (if medical personnel don’t offer them) are:
- Blood work, a placental exam, an autopsy and genetic testing.
- A social worker or counselor, bereavement resources and religious or chaplain support.
- The option to be isolated from the labor rooms.
- Someone to take photos of you and your baby, typically either a nurse or an outside group.
- A small cooling cot that allows parents to spend more time with their babies after a stillbirth. If one is not available, you can ask for ice packs to put in the swaddle or the bassinet.
- A mold of your baby’s hands and feet.
- Information about burial or cremation services.
- Guidance on what to do if your milk comes in.
Getting an autopsy after a stillbirth.
Whether to have an autopsy is a personal decision. It may not reveal a cause of death, but it might provide important information about your stillbirth and contribute to broader stillbirth research. Autopsies can be useful if you are considering another pregnancy in the future. Families also told us that an autopsy can help parents feel they did everything they could to try to understand why their baby died.
But several families told us their health care providers didn’t provide them with the right information to help with that decision. Some aren’t trained in the advantages of conducting an autopsy after a stillbirth, or in when and how to sensitively communicate with parents about it. Some, for example, don’t explain that patients can still have an open-casket funeral or other service after an autopsy because the incisions can easily be covered by clothing. Others may not encourage an autopsy because they think they already know what caused the stillbirth or don’t believe anything could have been done to prevent it. In addition, not all hospitals have the capacity to do an autopsy, but there may be private autopsy providers that can perform one at an additional cost.
You can read more about autopsies in our reporting.
Paying for an autopsy after a stillbirth.
If you decide you want an autopsy, you may wonder whether you need to pay out-of-pocket for it. Several families told us their providers gave them incomplete or incorrect information. Many larger or academic hospitals offer autopsies at no cost to patients. Some insurance companies also cover the cost of an autopsy after a stillbirth.
When hospitals don’t provide an autopsy, they may give you names of private providers. That was the case for Rachel Foran. The hospital gave her and her husband a list of numbers to call if they wanted to pay for an autopsy themselves. The process, she said, shocked her.
“I had just delivered and we had to figure out what to do with his body,” Foran said. “It felt totally insane that that was what we had to do and that we had to figure it out on our own.”
An independent autopsy, records show, cost them $5,000.
What is a certificate of stillbirth and how do I get one?
A fetal death certificate is the official legal document that records the death. This is the document used to gather data on and track the number of stillbirths in the country. Many states also issue a certificate of stillbirth or a certificate of birth resulting in stillbirth, which acknowledge the baby’s birth. Families told us they appreciated having that document, since typical birth certificates are not issued for stillbirths. You can usually request a certificate from the vital records office.
Grieving After a Stillbirth
What are the effects of stillbirths on parents and families?
Over and over, families told us the effects of losing a baby can reverberate for a lifetime.
Bereavement support groups may help provide a space to share experiences and resources. Hospitals and birth centers may suggest a local grief group.
We talked with Anna Calix, a maternal health expert who became active in perinatal loss prevention after her son Liam was stillborn on his due date in 2016. Calix leads grief support groups for people of color in English and Spanish.
She suggested rededicating the time you would have spent taking care of a new baby to the grief process.
“You can do that by addressing your own thoughts and feelings and really experiencing those feelings,” Calix said. “We like to push those feelings away or try to do something to distract and avoid, but no matter what we do, the feelings are there.”
It’s important, she said, to give yourself permission to grow your connection with your child and work through thoughts of guilt or blame.
What You Might Say and Do After a Loved One Experiences a Stillbirth
Finding the right words can be difficult. The following are a few suggestions from parents who went through a stillbirth.
Helpful:
- Acknowledge the loss and offer condolences.
- Ask if the baby was named and use the name.
- Allow space for the family to talk about their baby.
Unhelpful:
- Avoid talking about the baby.
- Minimize the loss or compare experiences.
- Start statements with “at least.”
Suggested phrases to avoid:
- “You’re young. You can have more kids.”
- “At least you have other children.”
- “These things just happen.”
- “Your baby is in a better place now.”

Our blood-brain barrier stops bugs and toxins getting to our brain. Here’s how it works
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our brain is an extremely complex and delicate organ. Our body fiercely protects it by holding onto things that help it and keeping harmful things out, such as bugs that can cause infection and toxins.
It does that though a protective layer called the blood-brain barrier. Here’s how it works, and what it means for drug design.
First, let’s look at the circulatory system
Adults have roughly 30 trillion cells in their body. Every cell needs a variety of nutrients and oxygen, and they produce waste, which needs to be taken away.
Our circulatory system provides this service, delivering nutrients and removing waste.
Where the circulatory system meets your cells, it branches down to tiny tubes called capillaries. These tiny tubes, about one-tenth the width of a human hair, are also made of cells.
But in most capillaries, there are some special features (known as fenestrations) that allow relatively free exchange of nutrients and waste between the blood and the cells of your tissues.
It’s kind of like pizza delivery
One way to think about the way the circulation works is like a pizza delivery person in a big city. On the really big roads (vessels) there are walls and you can’t walk up to the door of the house and pass someone the pizza.
But once you get down to the little suburban streets (capillaries), the design of the streets means you can stop, get off your scooter and walk up to the door to deliver the pizza (nutrients).
We often think of the brain as a spongy mass without much blood in it. In reality, the average brain has about 600 kilometres of blood vessels.
The difference between the capillaries in most of the brain and those elsewhere is that these capillaries are made of specialised cells that are very tightly joined together and limit the free exchange of anything dissolved in your blood. These are sometimes called continuous capillaries.
This is the blood brain barrier. It’s not so much a bag around your brain stopping things from getting in and out but more like walls on all the streets, even the very small ones.
The only way pizza can get in is through special slots and these are just the right shape for the pizza box.
The blood brain barrier is set up so there are specialised transporters (like pizza box slots) for all the required nutrients. So mostly, the only things that can get in are things that there are transporters for or things that look very similar (on a molecular scale).
The analogy does fall down a little bit because the pizza box slot applies to nutrients that dissolve in water. Things that are highly soluble in fat can often bypass the slots in the wall.
Why do we have a blood-brain barrier?
The blood brain barrier is thought to exist for a few reasons.
First, it protects the brain from toxins you might eat (think chemicals that plants make) and viruses that often can infect the rest of your body but usually don’t make it to your brain.
It also provides protection by tightly regulating the movement of nutrients and waste in and out, providing a more stable environment than in the rest of the body.
Lastly, it serves to regulate passage of immune cells, preventing unnecessary inflammation which could damage cells in the brain.
What it means for medicines
One consequence of this tight regulation across the blood brain barrier is that if you want a medicine that gets to the brain, you need to consider how it will get in.
There are a few approaches. Highly fat-soluble molecules can often pass into the brain, so you might design your drug so it is a bit greasy.
Another option is to link your medicine to another molecule that is normally taken up into the brain so it can hitch a ride, or a “pro-drug”, which looks like a molecule that is normally transported.
Using it to our advantage
You can also take advantage of the blood brain barrier.
Opioids used for pain relief often cause constipation. They do this because their target (opioid receptors) are also present in the nervous system of the intestines, where they act to slow movement of the intestinal contents.
Imodium (Loperamide), which is used to treat diarrhoea, is actually an opioid, but it has been specifically designed so it can’t cross the blood brain barrier.
This design means it can act on opioid receptors in the gastrointestinal tract, slowing down the movement of contents, but does not act on brain opioid receptors.
In contrast to Imodium, Ozempic and Victoza (originally designed for type 2 diabetes, but now popular for weight-loss) both have a long fat attached, to improve the length of time they stay in the body.
A consequence of having this long fat attached is that they can cross the blood-brain barrier, where they act to suppress appetite. This is part of the reason they are so effective as weight-loss drugs.
So while the blood brain barrier is important for protecting the brain it presents both a challenge and an opportunity for development of new medicines.

Winning The Biological Arms Race
The human immune system (and indeed, other immune systems, but we are all humans here, after all) is in a constant state of war with pathogens, and that war is a constant biological arms race:
- We improve our defenses and destroy the attackers; the 1% of pathogens that survived now “know” how to counter that trick.
- The pathogens wreak havoc in our systems; the n% of us that survive now have immune systems that “know” how to counter that trick.
Vaccines are a mighty tool in our favor here, because they’re the technology that stops our n% from also being a very low number.
With vaccines, we can effectively pass on established defenses onto the population at large, as this cute video explains very well and very simply in 57 seconds:
Click Here If The Embedded Video Doesn’t Load Automatically!
The problem with vaccines
The problem is that this accelerates the arms race. It’s like a chess game where we are able to respond to every move quickly (which is good for us), and/but this means passing the move over to our opponent sooner.
That problem’s hard to avoid, because the alternative has always been “let people die in much larger numbers”.
Traditional vs mRNA vaccines
A quick refresher before we continue to the big news of the day:
- Traditional vaccines use a disabled version of a pathogen to trigger an immune response that will teach the body to recognize the pathogen ready for when the full version shows up
- mRNA vaccines use a custom-made bit of genetic information to tell the body to make its own harmless fake pathogen and then respond to the harmless fake pathogen it made.
Note: this happens independently of the host’s DNA, so no, it does not change your DNA
See also: The Truth About Vaccines
Here’s a more detailed explainer (with a helpful diagram) using the COVID mRNA vaccine as an example:
Genome.gov | How does an mRNA vaccine work?
However, this still leaves us “chasing strains”, because as the pathogen (in this case, a virus) adapts, the vaccine has to be updated too, hence all the boosters.
This is a lot like a security update for your computer’s antivirus software. They’re annoying, but they do an important job.
No more “chasing strains”
The press conference soundbite on this sums it up well:
❝Scientists at UC Riverside have demonstrated a new, RNA-based vaccine strategy that is effective against any strain of a virus and can be used safely even by babies or the immunocompromised.❞
Read in full: Vaccine breakthrough means no more chasing strains
You may be wondering: what makes this one effective against any strain?
❝What I want to emphasize about this vaccine strategy is that it is broad.
It is broadly applicable to any number of viruses, broadly effective against any variant of a virus, and safe for a broad spectrum of people. This could be the universal vaccine that we have been looking for.
Viruses may mutate in regions not targeted by traditional vaccines. However, we are targeting their whole genome with thousands of small RNAs. They cannot escape this.❞
Importantly, this means it can be applied not just to one disease, let alone just one strain of COVID. Rather, it can be used for a wide variety of viruses that have similar viral functions—COVID / SARS in general, including influenza, and even viruses such as dengue.
How it does this: the above article explains in more detail, but in few words: it targets tiny strings of the genome that are present in all strains of the virus.
Illustrative example: if you wanted to block 10almonds (please don’t), you could block our email address.
But if we were malicious (we’re not) we could be sneaky and change it, so you’d have to block the new one, and the cycle repeats.
But if you were block all emails containing the tiny string of characters “10almonds”, changing our email address would no longer penetrate your defenses.
Now imagine also blocking strings such as “One-Minute Book Review” and “Today’s almonds have been activated by” and other strings we use in every email.
Now multiply this by thousands of strings (because genomes are much larger than our little newsletter), and you see its effectiveness!
Great! How can I get this?
It’s still in the testing stages for now; this is “breaking news” science, after all.
The study itself
…is paywalled for now, sadly, but if you happen to have institutional access, here it is:
Take care!

Maca Root: What It Does And Doesn’t Do
Maca root, or Lepidium meyenii, gets thought of as a root vegetable, though it’s in fact a cruciferous vegetable and more closely related to cabbage—notwithstanding that it also gets called “Peruvian ginseng”.
- Nutritionally, it’s full of all manner of nutrients (vitamins, minerals, fiber, and a wide array of phytochemicals)
- Medicinally, it’s long enjoyed traditional use against a wide variety of illnesses, including respiratory infections and inflammatory diseases.
It’s also traditionally an aphrodisiac.
Is it really anti-inflammatory?
Probably not… Unless fermented. This hasn’t been studied deeply, but a 2023 study found that non-fermented and fermented maca root extracts had opposite effects in this regard:
However, this was an in vitro study, so we can’t say for sure that the results will carry over to humans.
Is it really an aphrodisiac?
Actually yes, it seems so. Here’s a study in which 45 women with antidepressant-induced sexual dysfunction found it significantly improved both libido and sexual function:
❝In summary, maca root may alleviate antidepressant-induced sexual dysfunction as women age, particularly in the domain of orgasm❞
~ Dr. Christina Dording et al.

As for men, well these mice (not technically men) found it beneficial too:

(pardon the censorship; we’re trying to avoid people’s spam filters)
It did also improve fertility (and, actually in real men this time):
Does Lepidium meyenii (Maca) improve seminal quality?
Oh, to be in the mood
Here’s an interesting study in which 3g/day yielded significant mood improvement in these 175 (human) subjects:
And yes, it was found to be “well-tolerated” which is scientist-speak for “this appears to be completely safe, but we don’t want to commit ourselves to an absolutist statement and we can’t prove a negative”.
Oh, to have the energy
As it turns out, maca root does also offer benefits in this regard too:
(that’s not an added ingredient; it’s just a relevant chemical that the root naturally contains)
