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.

The Sleep Solution – by Dr. Chris Winter
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.
This book’s blurb contains a bold claim:
❝If you want to fix your sleep problems, Internet tips and tricks aren’t going to do it for you. You need to really understand what’s going on with your sleep—both what your problems are and how to solve them.❞
So, how well does it deliver, on the strength of being a whole book rather than an Internet article?
Well, for sure we wouldn’t have the room to include all the information that Dr. Winter does, in one of our main feature articles here (we’d need to spread it out over several weeks, at least).
He examines very thoroughly what is going on with sleep, sleep disturbance, and sleep deprivation. What’s going on with the different phases of sleep (far more than your phone’s sleep app will), and how imbalances in these can cause problems.
While the usual sleep hygiene tips do get a mention, he broadly assumes we know that part already. Instead, he focuses on aligning as many components as possible of our rich and interesting circadian rhythm. Yes, even if that means clawing our way out of insomnia and/or a bad sleep schedule (or lack of coherent sleep schedule) first. He gives plenty of practical advice on how to do that.
Bottom line: if you’d like to more deeply understand sleep, what is or isn’t wrong with yours, and how you can fix it, this book is a great resource.

Death by Food Pyramid – by Denise Minger

This one is less about “here’s the perfect way of eating” or even “these specific foods are ontologically evil”, but more about teaching science literacy.
The author explores various health trends from the 70s until time of writing (the book was published in 2014), what rationales originally prompted them, and what social phenomena either helped them to persist, or caused them to get dropped quite quickly.
Of course, even in the case of fads that are societally dropped quite quickly, on an individual level there will always be someone just learning about it for the first time, reading some older material, and thinking “that sounds like just the miracle life-changer I need!”
What she teaches the reader to do is largely what we do a lot of here at 10almonds—examine the claims, go to the actual source material (studies! Not just books about studies!), and see whether the study conclusions actually support the claim, to start with, and then further examine to see if there’s some way (or sometimes, a plurality of ways) in which the study itself is methodologically flawed.
Which does happen sometimes, do actually watch out for that!
The style is quite personal and entertaining for the most part, and yet even moving sometimes (the title is not hyperbole; deaths will be discussed). As one might expect of a book teaching science literacy, it’s very easy to read, with copious footnotes (well, actually they are at the back of the book doubling up as a bibliography, but they are linked-to throughout) for those who wish to delve deeper—something the author, of course, encourages.
Bottom line: if you’d like to be able to sort the real science from the hype yourself, then this book can set you on the right track!

Mosquitoes can spread the flesh-eating Buruli ulcer. Here’s how you can protect yourself
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.
Each year, more and more Victorians become sick with a flesh-eating bacteria known as Buruli ulcer. Last year, 363 people presented with the infection, the highest number since 2004.
But it has been unclear exactly how it spreads, until now. New research shows mosquitoes are infected from biting possums that carry the bacteria. Mozzies spread it to humans through their bite.
What is Buruli ulcer?
Buruli ulcer, also known as Bairnsdale ulcer, is a skin infection caused by the bacterium Mycobacterium ulcerans.
It starts off like a small mosquito bite and over many months, slowly develops into an ulcer, with extensive destruction of the underlying tissue.
While often painless initially, the infection can become very serious. If left untreated, the ulcer can continue to enlarge. This is where it gets its “flesh-eating” name.
Thankfully, it’s treatable. A six to eight week course of specific antibiotics is an effective treatment, sometimes supported with surgery to remove the infected tissue.
Where can you catch it?
The World Health Organization considers Buruli ulcer a neglected tropical skin disease. Cases have been reported across 33 countries, primarily in west and central Africa.
However, since the early 2000s, Buruli ulcer has also been increasingly recorded in coastal Victoria, including suburbs around Melbourne and Geelong.
Scientists have long known Australian native possums were partly responsible for its spread, and suspected mosquitoes also played a role in the increase in cases. New research confirms this.
Our efforts to ‘beat Buruli’
Confirming the role of insects in outbreaks of an infectious disease is achieved by building up corroborating, independent evidence.
In this new research, published in Nature Microbiology, the team (including co-authors Tim Stinear, Stacey Lynch and Peter Mee) conducted extensive surveys across a 350 km² area of Victoria.
We collected mosquitoes and analysed the specimens to determine whether they were carrying the pathogen, and links to infected possums and people. It was like contact tracing for mosquitoes.
Aedes notoscriptus was the mosquito identified as carrying the bacteria that caused Buruli ulcer.
Cameron Webb (NSW Health Pathology)Molecular testing of the mosquito specimens showed that of the two most abundant mosquito species, only Aedes notoscriptus (a widespread species commonly known as the Australian backyard mosquito) was positive for Mycobacterium ulcerans.
We then used genomic tests to show the bacteria found on these mosquitoes matched the bacteria in possum poo and humans with Buruli ulcer.
We further analysed mosquito specimens that contained blood to show Aedes notoscriptus was feeding on both possums and humans.
To then link everything together, geospatial analysis revealed the areas where human Buruli ulcer cases occur overlap with areas where both mosquitoes and possums that harbour Mycobacterium ulcerans are active.
Stop its spread by stopping mozzies breeding
The mosquito in this study primarily responsible for the bacteria’s spread is Aedes notoscriptus, a mosquito that lays its eggs around water in containers in backyard habitats.
Controlling “backyard” mosquitoes is a critical part of reducing the risk of many global mosquito-borne disease, especially dengue and now Buruli ulcer.
You can reduce places where water collects after rainfall, such as potted plant saucers, blocked gutters and drains, unscreened rainwater tanks, and a wide range of plastic buckets and other containers. These should all be either emptied at least weekly or, better yet, thrown away or placed under cover.
Mosquitoes can lay eggs in a wide range of water-filled items in the backyard.
Cameron Webb (NSW Health Pathology)There is a role for insecticides too. While residual insecticides applied to surfaces around the house and garden will reduce mosquito populations, they can also impact other, beneficial, insects. Judicious use of such sprays is recommended. But there are ecological safe insecticides that can be applied to water-filled containers (such as ornamental ponds, fountains, stormwater pits and so on).
Recent research also indicates new mosquito-control approaches that use mosquitoes themselves to spread insecticides may soon be available.
How to protect yourself from bites
The first line of defence will remain personal protection measures against mosquito bites.
Covering up with loose fitted long sleeved shirts, long pants, and covered shoes will provide physical protection from mosquitoes.
Applying topical insect repellent to all exposed areas of skin has been proven to provide safe and effective protection from mosquito bites. Repellents should include diethytolumide (DEET), picaridin or oil of lemon eucalyptus.
While the rise in Buruli ulcer is a significant health concern, so too are many other mosquito-borne diseases. The steps to avoid mosquito bites and exposure to Mycobacteriam ulcerans will also protect against viruses such as Ross River, Barmah Forest, Japanese encephalitis, and Murray Valley encephalitis.

What does it mean to be transgender?
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.
Transgender media coverage has surged in recent years for a wide range of reasons. While there are more transgender television characters than ever before, hundreds of bills are targeting transgender people’s access to medical care, sports teams, gender-specific public spaces, and other institutions.
Despite the increase in conversation about the transgender community, public confusion around transgender identity remains.
Read on to learn more about what it means to be transgender and understand challenges transgender people may face.
What does it mean to be transgender?
Transgender—or “trans”—is an umbrella term for people whose gender identity or gender expression does not conform to their sex assigned at birth. People can discover they are trans at any age.
Gender identity refers to a person’s inner sense of being a woman, a man, neither, both, or something else entirely. Trans people who don’t feel like women or men might describe themselves as nonbinary, agender, genderqueer, or two-spirit, among other terms.
Gender expression describes the way a person communicates their gender through their appearance—such as their clothing or hairstyle—and behavior.
A person whose gender expression doesn’t conform to the expectations of their assigned sex may not identify as trans. The only way to know for sure if someone is trans is if they tell you.
Cisgender—or “cis”—describes people whose gender identities match the sex they were assigned at birth.
How long have transgender people existed?
Being trans isn’t new. Although the word “transgender” only dates back to the 1960s, people whose identities defy traditional gender expectations have existed across cultures throughout recorded history.
How many people are transgender?
A 2022 Williams Institute study estimates that 1.6 million people over the age of 13 identify as transgender in the United States.
Is being transgender a mental health condition?
No. Conveying and communicating about your gender in a way that feels authentic to you is a normal and necessary part of self-expression.
Social and legal stigma, bullying, discrimination, harassment, negative media messages, and barriers to gender-affirming medical care can cause psychological distress for trans people. This is especially true for trans people of color, who face significantly higher rates of violence, poverty, housing instability, and incarceration—but trans identity itself is not a mental health condition.
What is gender dysphoria?
Gender dysphoria describes a feeling of unease that some trans people experience when their perceived gender doesn’t match their gender identity, or their internal sense of gender. A 2021 study of trans adults pursuing gender-affirming medical care found that most participants started experiencing gender dysphoria by the time they were 7.
When trans people don’t receive the support they need to manage gender dysphoria, they may experience depression, anxiety, social isolation, suicidal ideation, substance use disorder, eating disorders, and self-injury.
How do trans people manage gender dysphoria?
Every trans person’s experience with gender dysphoria is unique. Some trans people may alleviate dysphoria by wearing gender-affirming clothing or by asking others to refer to them by a new name and use pronouns that accurately reflect their gender identity. The 2022 U.S. Trans Survey found that nearly all trans participants who lived as a different gender than the sex they were assigned at birth reported that they were more satisfied with their lives.
Some trans people may also manage dysphoria by pursuing medical transition, which may involve taking hormones and getting gender-affirming surgery.
Access to gender-affirming medical care has been shown to reduce the risk of depression and suicide among trans youth and adults.
To learn more about the trans community, visit resources from the National Center for Transgender Equality, the Trevor Project, PFLAG, and Planned Parenthood.
If you or anyone you know is considering suicide or self-harm or is anxious, depressed, upset, or needs to talk, call the Suicide & Crisis Lifeline at 988 or text the Crisis Text Line at 741-741. For international resources, here is a good place to begin.

A Surprisingly Powerful Tool: Eye Movement Desensitization & Reprocessing
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.
Eye Movement Desensitization & Reprocessing (EMDR)
What skeletons are in your closet? As life goes on, most of accumulate bad experiences as well as good ones, to a greater or lesser degree. From clear cases of classic PTSD, to the widely underexamined many-headed beast that is C-PTSD*, our past does affect our present. Is there, then, any chance for our future being different?
*PTSD is typically associated with military veterans, for example, or sexual assault survivors. There was a clear, indisputable, Bad Thing™ that was experienced, and it left a psychological scar. When something happens to remind us of that—say, there are fireworks, or somebody touches us a certain way—it’ll trigger an immediate strong response of some kind.
These days the word “triggered” has been popularly misappropriated to mean any adverse emotional reaction, often to something trivial.
But, not all trauma is so clear. If PTSD refers to the result of that one time you were smashed with a sledgehammer, C-PTSD (Complex PTSD) refers to the result of having been hit with a rolled-up newspaper every few days for fifteen years, say.
This might have been…
- childhood emotional neglect
- a parent with a hair-trigger temper
- bullying at school
- extended financial hardship as a young adult
- “just” being told or shown all too often that your best was never good enough
- the persistent threat (real or imagined) of doom of some kind
- the often-reinforced idea that you might lose everything at any moment
If you’re reading this list and thinking “that’s just life though”, you might be in the estimated 1 in 5 people with (often undiagnosed) C-PTSD.
For more on C-PTSD, see our previous main feature:
So, what does eye movement have to do with this?
Eye Movement Desensitization & Reprocessing (EMDR) is a therapeutic technique whereby a traumatic experience (however small or large; it could be the memory of that one time you said something very regrettable, or it could be some horror we couldn’t describe here) is recalled, and then “detoothed” by doing a bit of neurological jiggery-pokery.
How the neurological jiggery-pokery works:
By engaging the brain in what’s called bilateral stimulation (which can be achieved in various ways, but a common one is moving the eyes rapidly from side to side, hence the name), the event can be re-processed, in much the same way that we do when dreaming, and relegated safely to the past.
This doesn’t mean you’ll forget the event; you’d need to do different exercises for that.
See also our previous main feature:
The Dark Side Of Memory (And How To Make Your Life Better)
That’s not the only aspect of EMDR, though…
EMDR is not just about recalling traumatic events while moving your eyes from side-to-side. What an easy fix that would be! There’s a little more to it.
The process also involves (ideally with the help of a trained professional) examining what other memories, thoughts, feelings, come to mind while doing that. Sometimes, a response we have today associated with, for example, a feeling of helplessness, or rage in conflict, or shame, or anything really, can be connected to previous instances of feeling the same thing. And, each of those events will reinforce—and be reinforced by—the others.
An example of this could be an adult who struggles with substance abuse (perhaps alcohol, say), using it as a crutch to avoid feelings of [insert static here; we don’t know what the feelings are because they’re being avoided], that were first created by, and gradually snowballed from, some adverse reaction to something they did long ago as a child, then reinforced at various times later in life, until finally this adult doesn’t know what to do, but they do know they must hide it at all costs, or suffer the adverse reaction again. Which obviously isn’t a way to actually overcome anything.
EMDR, therefore, seeks to not just “detooth” a singular traumatic memory, but rather, render harmless the whole thread of memories.
Needless to say, this kind of therapy can be quite an emotionally taxing experience, so again, we recommend trying it only under the guidance of a professional.
Is this an evidence-based approach?
Yes! It’s not without its controversy, but that’s how it is in the dog-eat-dog world of academia in general and perhaps psychotherapy in particular. To give a note to some of why it has some controversy, here’s a great freely-available paper that presents “both sides” (it’s more than two sides, really); the premises and claims, the criticisms, and explanations for why the criticisms aren’t necessarily actually problems—all by a wide variety of independent research teams:
Research on Eye Movement Desensitization & Reprocessing (EMDR) as a Treatment for PTSD
To give an idea of the breadth of applications for EMDR, and the evidence of the effectiveness of same, here are a few additional studies/reviews (there are many):
- An Eye Movement Desensitization and Reprocessing (EMDR) Group Intervention for Syrian Refugees With Post-traumatic Stress Symptoms: Results of a Randomized Controlled Trial
- Cognitive Behavioral Therapy vs. Eye Movement Desensitization and Reprocessing for Treating Panic Disorder: A Randomized Controlled Trial
- Eye movement desensitization and reprocessing (EMDR) therapy in the treatment of depression: a matched pairs study in an inpatient setting
- Emergency room intervention to prevent post concussion-like symptoms and post-traumatic stress disorder. A pilot randomized controlled study of a brief eye movement desensitization and reprocessing intervention versus reassurance or usual care
As for what the American Psychiatric Association says about it:
❝After assessing the 120 outcome studies pertaining to the focus areas, we conclude that for two of the areas (i.e., PTSD in children and adolescents and EMDR early interventions research) the strength of the evidence is rated at the highest level, whereas the other areas obtain the second highest level.❞
