Why read it?
If you think freshwater sponges are cool
If you think MALDI Mass Spec is cool
If you think bacteria are cool
If you think specialized metabolism is cool
If you're bored

I'd like to get a question out of the way first… “Why is the 'sample size' so small (2 sponges)?”

Answer: this was a highly exploratory project
We recovered 851 bacterial isolates from just these two samples and had no idea if these experiments would work.

Do humans really mark the PINNACLE OF EVOLUTION, or do VIRUSES?
While we’ve evolved along a pathway of ever-increasing complexity, VIRUSES HAVE STREAMLINED, SUCCESSFULLY JETTISONING ALL BUT A HANDFUL OF ESSENTIAL GENES, research...suggests.>
Because viruses are usually so basic many biologists DIDN’T THINK they could even be classified as a
LIFE FORM. But just over a decade ago,
OUR VIEW OF VIRUSES BEGAN TO SHIFT.
French scientists who were examining a MYSTERY MICROBE that looked like a bacterium, but was>
genetically quite different to bacteria realized they’d discovered a giant virus. They named this bacteria look-alike the “MIMICKING MICROBE,” or “MIMIVIRUS”.
And the mimivirus wasn’t only PHYSICALLY LARGE...it CARRIED MORE THAN 1,000 GENES – a huge genome for a virus, just a>

If you’re considering studying blockage of GPCRs in #LongCovid or related conditions, please start w/ the understanding that humans are not sterile...and that common human organisms/pathogens express proteins/metabolites that block/dysregulate GPCR signaling
2/ Herpesvirus re-activation is common in #COVID-19, and may impact some LongCovid cases. The herpesviruses alone (EBV, CMV etc) create a wide range of proteins that block GPCR signaling: ncbi.nlm.nih.gov/pmc/articles/P… Indeed, viral hijacking of GPCRs is a big topic in cancer research
3/ Beyond that, many commensal #bacteria derived from the human #microbiome appear capable of expressing metabolites that are GPCR mimics, that directly impact GPCR signaling. That means even changing microbiome dynamics could impact GPCR-related issues: ncbi.nlm.nih.gov/pmc/articles/P…

And so Day 3 of my story of God at work in my life as part of #OfGodAndMe #ThisNunsStory series. Yesterday mention of the book, The Silver Sword seems to have struck a chord with many so perhaps its not out of place to mention that today 7th April is #Worldhealthday 1/20
Ian Serraillier ended his talks by showing this photo with the words, ‘No child should ever again have that expression on his face’. My hope this the UK as host of the upcoming #G7 summit will prioritise Universal health care for all. #UCH 2/20
So back to my story. Living at home again and my dream of religious life gone out the window I applied and got a place for September at Brighton College of Education to do a cert ed in biological science & primary education 3/20

1/ A: Celebrate the mild #flu season & take what we have learned this year to inform future behavior. Harmful germs are not going away. 🦠 Illness from bacteria & viruses that make us sick do not “strengthen” the #immune system & contribute to significant complications & death. Image
2/ The lack of infectious illnesses will not #weaken your #immunesystem. Public health measures to combat #COVID19 including social distancing, masks, & extra hand washing greatly reduced the incidence of some bad microbes that cause common infectious illnesses such as the flu.
3/ More than 15,000 US deaths attributed to the #flu were averted this year. Other common viruses, like rhinoviruses, did not decrease as consistently. #Bacteria & #viruses that cause illness will continue to exist. go.nature.com/2OxkiUv

Today is the start of #SHW2020! Each day this week, I'll be tweeting about Britain's long, tempestuous and ever-so-slightly bonkers love–hate relationship with its #sexualhealth.

Darlings, brace yourselves. 💋 #SHW20 Image
We begin with the Victorians, who, contrary to popular belief, were obsessed with sex. In the C19, the only known #STIs were syphilis and gonorrhoea. Diagnosis depended on observable symptoms (no blood tests/smears). Effective treatments were non-existent. Image: @ExploreWellcome Image
In 1864 the British government introduced the Contagious Diseases Acts, intended to protect the armed forces through 'regulation' of 'common prostitutes'. The Acts gave police almost-unlimited discretionary powers to arrest any woman they thought might be soliciting. Image: HCPP Image

Check out this interview I did w/ @resiapretorius 👉 Resia + team have published dozens of papers detailing how inflammatory products created by #bacteria/#viruses in human blood can drive clotting, red blood cell deformability, vasculature problems etc: microbeminded.com/2020/08/06/int… Image
2/ Conditions studied by Resia and team include #Alzheimer’s + #Parkinson’s. For example they identified toxic gingipain proteins created by oral #pathogen p. gingivalis in the blood of Parkinson’s patients, and showed how the gingipains can increase hypercoagulation ImageImage
3/ I am truly excited about the fact that we are working to send her team #ME/CFS and #PTLDS (chronic #lyme disease) blood samples that they will analyze for many of the same issues 🙌

El #calamar hawaiano (Euprymna scolopes) ha atraído una gran atención en los últimos años, y no solo por su adorable apariencia, sino por su relación simbiótica con una pequeña #bacteria muy particular que hace que se encienda como una bombilla. 🦑💡 Image
Los calamares hawaianos tienen un órgano especializado fascinante en su saco de tinta que produce luz todas las noches (tanto para que los calamares puedan evitar a los depredadores como para ayudarlos en la caza de sus propias presas). Image
Y, ¿a quién agradecer esta capacidad de iluminación nocturna? Pues, a un pequeño #microorganismo bacteriano, conocido como Vibrio fischeri.
