A team of bioengineers and biomedical scientists from the University of Sydney and the Children’s Medical Research Institute (CMRI) at Westmead have used 3D photolithographic printing to create a complex environment for assembling tissue that mimics the architecture of an organ.
The teams were led by Professor Hala Zreiqat and Dr. Peter Newman at the University of Sydney’s School of Biomedical Engineering and developmental biologist Professor Patrick Tam who leads the CMRI’s Embryology Research Unit. Their paper was published in Advanced Science.

A team of scientists led by Masaya Hagiwara of RIKEN national science institute in Japan has developed an ingenious device, using layers of hydrogels in a cube-like structure, that allows researchers to construct complex 3D organoids without using elaborate techniques. The group also recently demonstrated the ability to use the device to build organoids that faithfully reproduce the asymmetric genetic expression that characterizes the actual development of organisms. The device has the potential to revolutionize the way we test drugs, and could also provide insights into how tissues develop and lead to better techniques for growing artificial organs.
Scientists have long struggled to create organoids—organ-like tissues grown in the laboratory—to replicate actual biological development. Creating organoids that function similarly to real tissues is vital for developing medicines since it is necessary to understand how drugs move through various tissues. Organoids also help us gain insights into the process of development itself and are a stepping stone on the way to growing whole organs that can help patients.
Teeth don’t grow back once we become adults: any wear and tear is permanent – as those of us with fillings will know – which is why it’s important to keep them as clean and healthy as we can.
However, this is something scientists are now looking to change.
It’s been announced that clinical trials for a potential tooth regrowth treatment are set to begin in July 2024, building on decades of research in the field. If those trials are successful, therapeutic drugs could be available by 2030.
MaxCyte, Inc., a leading, cell-engineering focused company providing enabling platform technologies to advance the discovery, development and commercialization of next-generation cell-based therapeutics and to support innovative, cell-based research, today announced the signing of a strategic partnership with Prime Medicine, Inc., a biotechnology company committed to delivering a new class of differentiated one-time curative genetic therapies.
Black hair? Green eyes? More than 160 genes determine your coloration, and their interactions are incredibly complicated.
Multiple sclerosis (MS) can cause a huge range of symptoms in different patients, and the severity can vary dramatically. It is an inflammatory condition in which the body attacks myelin sheaths, a protective insulation surrounding nerve cells. This can cause fatigue, pain, paralysis, and symptoms that gradually get worse. MS can be very difficult to diagnose because the symptoms can be so different in different patients, and the presence of brain lesions is the clearest indication of the disease. MRIs that can reveal those brain lesions are only useful once the disease have progressed to the point of brain damage, however.
The innate immune system presents a potential option for monitoring the progression of MS. The disease causes inflammation, so researchers tracked immune cells in the brain called macrophages, and assessed brain inflammation in a mouse model of MS. The findings have been reported in Science Translational Medicine.
Often seen negatively cannabis seen truthfully is a miracle plant even derivatives like cbd have cured some of the hardest mental disorders to cure like dementia alleviating symptoms to bring a person closer to health than before. Also now with this study veterans often seen incurable due to the unknown factors of ptsd and unknown factors of the human brain now are seeing relief through cannabis usage in a therapeutic setting 😀 Even the plant itself is some sorta miracle plant alleviating some thought incurable diseases.
Milekic’s morning could be an advertisement for the potential of AI to transform health care. Mount Sinai is among a group of elite hospitals pouring hundreds of millions of dollars into AI software and education, turning their institutions into laboratories for this technology. They’re buoyed by a growing body of scientific literature, such as a recent study finding AI readings of mammograms detected 20 percent more cases of breast cancer than radiologists — along with the conviction that AI is the future of medicine.
Researchers are also working to translate generative AI, which backs tools that can create words, sounds and text, into a hospital setting. Mount Sinai has deployed a group of… More.
Mount Sinai and other elite hospitals are pouring millions of dollars into chatbots and AI tools, as doctors and nurses worry the technology will upend their jobs.
Summary: Probiotics might play a vital role in preventing cognitive decline associated with aging. By providing participants suffering from mild cognitive impairment with the probiotic Lactobacillus rhamnosus GG for three months, researchers observed enhanced cognitive performance and gut microbiome modifications.
The study suggests that altering gut microbiome might be a strategic approach to enhancing cognitive function in individuals with mild cognitive impairment. If replicated, these findings could revolutionize preventive strategies in cognitive health using gut microbiome-focused approaches.
