google's search suggestion feature helps us to articulate a question that we've all been wondering about but have never been able to put into words: "Can bacteria make smarter?"
scientists of tumblr, what is a concept that no matter how may times you study it, you'll forget it within 24 hours?
In a new study, scientists with the University of Florida have found that a combination of silver nanoparticles and antibiotics is effective against antibiotic-resistant bacteria.
The researchers hope to turn this discovery into viable treatment for some types of antibiotic-resistant infections. Antibiotic-resistant infections kill more than a million people globally each year.
For centuries, silver has been known to have antimicrobial properties. However, silver nanoparticles—microscopic spheres of silver small enough to operate at the cellular level—represent a new frontier in using the precious metal to fight bacteria.
In this study, the research team tested whether commercially available silver nanoparticles boost the power of antibiotics and enable these drugs to counter the very bacteria that have evolved to withstand them.

i found another specimen of a super rare organism yesterday!
this is a rare and remarkable ciliate, a single-celled organism called Metopus verrucosus.
a few neat facts about it:
it’s an anaerobic organism! this means it prefers to live without oxygen
it lives deep in the mud of sulfur- & methane-rich bodies of saltwater. this one was found in the salt marsh estuary on the side of the garden state pkwy in south New Jersey!
it couldn’t survive in these noxious conditions by itself, though! the fuzzyness covering it’s cell is actually a type of bacteria that symbiotically lives on M. verrucosus.
this bacteria has the ability to metabolize sulfur and/or methane, processing these volatile stinky chemicals and turning it into energy, that it then shares with M. verrucosus!
i’m the only known person with this kind of footage of M. verrucosus! the paper The Santa Barbara Basin is an Oasis of Symbiosis has the only other photo i’ve seen of this organism, and it’s actually an HVEM (electron microscope) photo of a cross-section of the cell showing it’s endosymbiotic bacteria.
here are some more photos i took of other specimens:
Reminder that the "fittest" in "survival of the fittest" does not mean "strongest/most violent".
It refers to an animal that is best fitted to thriving in a given ecological niche. A fit animal is one that is successful at the tasks of finding food food and water, avoiding predators, and reproducing, by whatever means work best for their situation.
Mitochondria are primarily known as the powerhouse of the cell. However, these cellular organelles are required not only for providing energy: Professor Konstanze Winklhofer and her group at the Faculty of Medicine at Ruhr University Bochum, Germany, recently discovered that mitochondria play an important role in signal transduction in innate immune pathways.
They regulate a signaling pathway that helps to eliminate pathogens, but can cause damage through inflammation upon overactivation. The research team published their findings in the EMBO Journal.

Remember, folks, never pay to access a scientific article. Use a site like Sci-Hub, or failing that, e-mail the authors and request the data you need. Elsevier and their ilk are hoarders and thieves of knowledge, and they don’t deserve one cent more. Poach and pirate away; it is entirely justified.

Using a slime mold, an electrically conductive single-cell organism, researchers created a smartwatch that only works when the organism is healthy, which requires the user to give it food and care.
Devices such as cellphones, laptops, and smartwatches are constant companions for most people, spending days and nights in their pocket, on their wrist, or otherwise close at hand.
But when these technologies break down or a newer model hits stores, many people are quick to toss out or replace their device without a second thought. This disposability leads to rising levels of electronic waste—the fastest-growing category of waste, with 40 million tons generated each year.
Scientists wondered if they could change that fickle relationship by bringing devices to life—literally.
After creating the slime mold watch, they tested how the living device affected its wearer’s attitude toward technology.

The public paid for "Moderna's" vaccine, and now we're going to pay again (and again and again)
Moderna is quadrupling the cost of covid vaccines, from $26/dose to $110–130. Moderna CEO Stephane Bancel calls the price hike “consistent with the value” of the mRNA vaccines. Moderna’s manufacturing costs are $2.85/dose, for a 4,460% markup on every dose:

Your body deserves to feel safe. Your soul deserves to feel safe. I hope you find environments and invest in healing steps to accomplish this, because you and your body are good and deserving.
just learned that humans might have evolved smaller pupils and irises/more whites of our eyes so that it's easier for other humans to tell where we're looking as a way of communicating sudden threats. and now i'm thinking of every time i have been frantically giving my friend a Look to get out of an uncomfortable situation (or been on the receiving end). still using it to communicate sudden threats only this time his name is kyle
