Can someone smarter than I tell me if this has any implications regarding the Covid vaccine?
Genes contain instructions for making proteins, and a central dogma of biology is that this information flows from DNA to RNA to proteins. But only two percent of the human genome actually encodes proteins; the function of the remaining 98% remains largely unknown.
In an incredible feat that redefines biological boundaries, scientists have successfully engineered animal cells capable of photosynthesis.
This breakthrough, led by Professor Sachihiro Matsunaga at the University of Tokyo, could transform medical research and aid in advancing lab-grown meat production.
Photosynthesis, traditionally exclusive to plants, algae, and certain bacteria, is a process that uses sunlight, water, and carbon dioxide to produce oxygen and sugars – essentially “feeding” the organism.

Posted in biotech/medical, life extension | Leave a Comment on Scientists Determine Why Some Patients Don’t Respond Well to Wet Macular Degeneration Treatment, Show How New Experimental Drug Can Bridge Gap
A new study from researchers at Wilmer Eye Institute, Johns Hopkins Medicine explains not only why some patients with wet age-related macular degeneration (or “wet” AMD) fail to have vision improvement with treatment, but also how an experimental drug could be used with existing wet AMD treatments…
Wilmer Eye Institute researchers have found that ‘wet’ macular degeneration patients who don’t respond well to treatment have an increased protein in their eyes and that an experimental drug can help improve vision gains. ›
A new study describes a novel anti-cancer vaccine based on antigen-producing bacteria that can tackle solid and metastatic cancers [1].
Invading an invader
Years ago, scientists discovered that bacteria can colonize tumors [2]. Some bacteria are drawn to the tumor microenvironment due to factors such as necrotic tissue, hypoxia, and nutrient availability. For example, Clostridium species prefer anaerobic conditions and have been explored in tumor-targeting therapies. Salmonella and E. coli strains have also shown an affinity for tumors [3].
A study presents battery-free, polymer-based wearable devices that wrap around neurons, allowing for real-time monitoring and modulation of cellular activity. This innovation aims to restore neuronal function in conditions like multiple sclerosis.
More than paying lip service, the cells may offer new opportunities to research and treat various lip conditions.
This development comes from…
Researchers have designed a high-speed 3D bioprinter to accurately print human tissues.
Interestingly, this advanced bioprinter is capable of fabricating a diverse array of tissues, including both soft brain tissue and harder materials such as cartilage and bone.
MIT researchers have developed a battery-free, subcellular-sized device made of polymer designed to measure and modulate a neuron’s electrical and metabolic activity. When the device is activated by light, it can gently wrap around the neuron cell’s axons and dendrites without damaging the cells.
Scientists want to inject thousands of these tiny wireless devices into a patient’s central nervous system and then actuate them noninvasively using light. The light would penetrate the tissue and allow precise control of the devices, and thereby restore function in cases of neuronal degradation like multiple sclerosis (MS).
The MIT researchers developed these thin-film devices from a azobenzene, a soft polymer that readily reacts to light. Thin sheets of azobenzene roll into a cylinder when exposed to light, which enables them to wrap around cells. Researchers can control the direction and diameter of the rolling by changing the intensity and polarization of the light, producing a microtube with a diameter smaller than one micrometer.
