Interesting developments on the Science front – courtesy of Facebook pages, ‘Science Sphere’, ‘Hidden Power’, ‘’, ‘Human Scope’, ‘Astrophilesz’, etc… Although trials, experiments and studies show promise, I guess it will be some time yet before they are a reality.
Capsule endoscopy allows doctors to examine parts of the digestive tract, especially the small intestine, using a pill-sized camera. After being swallowed, the capsule travels naturally through the digestive system while capturing thousands of images.
Those images are transmitted to a recorder worn by the patient and later reviewed by a healthcare professional. Capsule endoscopy can help investigate problems such as unexplained gastrointestinal bleeding, inflammation, and certain small-intestinal abnormalities.
No traditional endoscope traveling through the entire small intestine — the camera makes the journey itself.
Modern medicine packed into something barely larger than a pill. – A Facebook post by ‘HumanScope’
Antiretroviral therapy, or ART, works by blocking different stages of HIV’s replication cycle. When taken consistently, treatment can suppress the amount of virus in the blood until standard tests can no longer detect it. This is called having an undetectable viral load.
The impact goes beyond protecting the person receiving treatment. Extensive evidence has established U=U: Undetectable = Untransmittable. A person with HIV who maintains an undetectable viral load has effectively zero risk of sexually transmitting HIV to their partner.
Treatment also protects the immune system by allowing CD4 cells to recover. Starting ART early and maintaining viral suppression means many people with HIV can now have a life expectancy approaching that of people without HIV, although outcomes still depend on factors such as access to care, other health conditions and how early treatment begins.
But “undetectable” does not mean cured. HIV can remain hidden in long-lived cellular reservoirs, so stopping treatment generally allows the virus to rebound. This is one reason researchers are still pursuing vaccines and treatments capable of eliminating or permanently controlling these reservoirs.
The transformation is remarkable: an HIV diagnosis once carried a very different prognosis. Today, with early diagnosis and effective treatment, many people can live long, healthy lives and cannot sexually transmit the virus while they remain durably undetectable. – A Facebook post by ‘Astrophilesz’
Brain-imaging studies show that inner speech recruits many of the same networks involved in speaking and hearing language. Areas involved in speech planning, motor control and auditory processing can become active even though no sound leaves your mouth.
Scientists have even recorded signals from the motor cortex and decoded words people were only imagining saying. Interestingly, imagined speech produced neural patterns similar to attempted spoken speech, although the signals were generally weaker.
Self-talk also appears to be deeply connected with how we regulate ourselves. Inner speech can help organize thoughts, rehearse information, solve problems, evaluate our own behavior and guide future actions. It is essentially one of the tools the brain uses to think about itself.
The form of that inner conversation matters too. Imagining an internal dialogue recruits a broader brain network than a simple internal monologue, including regions involved in understanding other people’s perspectives and mental states.
This doesn’t mean every thought magically rewires individual brain cells, but it does mean the words you repeatedly generate internally are real biological events occurring across neural networks. Your inner voice may be silent to everyone else, but your brain is listening. – A Facebook post by ‘Astrophilesz’
The idea uses Clostridium sporogenes, a soil bacterium that grows only where there is no oxygen.
That matters because the cores of many solid tumors are oxygen-starved, full of nutrients, and difficult for standard treatments to reach.
Researchers engineered this bacterium with a genetic “quorum sensing” circuit — a system that lets bacteria respond only when enough of them have gathered together.
In theory, this could help bacteria switch on survival or treatment-related genes inside tumors, while staying controlled elsewhere in the body. But this is still early synthetic biology.
The new study tested the genetic circuit using a fluorescent reporter, not cancer killing in patients.
The next challenge is to combine this control system with tumor-targeting bacteria and test it in preclinical cancer models. – A Facebook post by ‘Science Sphere’
Research has found that the brain emits significantly more biophotons than other tissues, and that emissions increase during neural activity. There is also emerging evidence linking biophoton output to oxidative stress, which is documented in depression, anxiety, and other mental health conditions. This is an active and still-developing field of science, but the foundation is solid: you are a body of light in a literal, measurable, biological sense. – A Facebook post by ‘Hidden Power’
