Stanford Scientists Discover New Biological Entities in Human Microbiome
Stanford scientists have discovered a new class of biological entities within the human microbiome called ‘Obelisks,’ which are a unique cross between viruses and viroids. With almost 30,000 different types found in microbiome samples from over 400 individuals, Obelisks are a widespread and completely new entity in the realm of microbiology. Their potential effects on human health and their role within the body are still unknown, sparking significant interest and further research in the field of microbiology.
Remarkable Fossilized Frog Unearthed in China, Shedding Light on Ancient Reproductive Behavior
A remarkable fossilized frog, Gansubatrachus qilianensis, dating back 100 million years has been unearthed in northwest China, shedding light on its reproductive behavior during the Cretaceous period. This discovery challenges previous assumptions about the reproductive capabilities of ancient frogs and toads, offering a unique glimpse into their evolutionary history. Lead author Baoxia Du emphasized the significance of understanding the reproductive strategies employed by early frogs, highlighting its importance in unraveling their complete reproductive history.

Scientists Develop World’s First 3D-Printed Brain Tissue with Potential to Revolutionize Neuroscience and Brain Disorder Treatments
Scientists in Wisconsin, USA, have achieved a groundbreaking feat in the field of neuroscience by developing the world’s first 3D-printed brain tissue that mimics the functionality of natural brain tissue. This development is a significant stride towards the advancement of treatments for neurological and neurodevelopmental disorders such as Alzheimer’s and Parkinson’s disease. The innovative approach employed by the scientists involved the use of a 3D printer that departed from the conventional method of stacking layers vertically. Instead, they utilized a horizontal layering technique and placed brain cells, specifically neurons derived from induced pluripotent stem cells, in a softer ‘bio-ink’ gel compared to previous attempts. According to Su-Chun Zhang, a professor of neuroscience and neurology at UW–Madison’s Waisman Center, the 3D-printed brain tissue provides a powerful model for understanding human brain cell communication. This breakthrough has the potential to revolutionize stem cell biology, neuroscience, and the understanding of various neurological and psychiatric disorders.
