Scientists decode key mutation in many cancers, pointing to expanded role of RNA in human gene expression
Posted by Genevieve Klien in categories: biotech/medical, genetics, health
Inside every cell, inside every nucleus, your continued existence depends on an incredibly complicated dance. Proteins are constantly wrapping and unwrapping DNA, and even minor missteps can lead to cancer. A new study from the University of Chicago reveals a previously unknown part of this dance—one with significant implications for human health.
In the study, published Oct. 2 in Nature, a team of scientists led by UChicago Prof. Chuan He, in collaboration with University of Texas Health Science Center at San Antonio Prof. Mingjiang Xu, found that RNA plays a significant role in how DNA is packaged and stored in your cells, via a gene known as TET2. The paper is titled “RNA m5C oxidation by TET2 regulates chromatin state and leukaemogenesis.”
This pathway also appears to explain a long-standing puzzle about why so many cancers and other disorders involve TET2-related mutations—and suggests a set of new targets for treatments.

139,000 Neurons of Adult Fruit Fly Brain Mapped For The First Time
Posted by Gemechu Taye in categories: biotech/medical, genetics, neuroscience
Unlocking the complexities of the fruit fly brain is a crucial step toward understanding the human brain. Fruit flies share many genetic similarities with humans, making them a valuable model organism for studying brain functions as well as diseases.
“An estimated 75% of human genes related to diseases have homologs in the fly genome,” Sebastian Seung, co-leader of the research team, told Interesting Engineering (IE).

Heavy-ion collisions could generate strongest electric fields ever
Posted by Gemechu Taye in category: energy
A theoretical analysis from researchers at Japan’s largest scientific research agency, RIKEN, suggests that intermediate energy heavy-ion collisions can give birth to the strongest electromagnetic fields ever observed.
Heavy ion collisions involve colliding large atomic nuclei at high velocities. Such collisions generate strong electric fields for a brief period, enabling scientists to study behaviors and phenomena that are otherwise remain hidden.
