New tool helps decipher gene behavior
Scientists have extensively researched the structure and sequence of genetic material and its interactions with proteins in the hope of understanding how our genetics and environment interact in diseases. This research has partly focused on 'epigenetic marks', which are chemical modifications to DNA, RNA, and the associated proteins (known as histones).
The 'switch' that keeps the immune system from attacking the body
Scientists uncover the mechanism by which cells mark the protein cGAS for degradation, which is critical in preventing the immune system from mistakenly attacking the body's own tissues.
Double trouble at chromosome ends
New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
New disease testing component facilitates lower-cost diagnostics
Biomedical researchers have developed a new, less expensive way to detect nuclease digestion -- one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.
Sniffing our way to better health
Imagine if we could inhale scents that delay the onset of cancer, inflammation, or neurodegenerative disease. Researchers are poised to bring this futuristic technology closer to reality.
Addressing societal concerns of genetic determinism of human behavior by linking environmental influences and genetic research
In a new perspective article, researchers underscore the importance of integrating environmental effects into genetic research. The authors discuss how failure to do so can perpetuate deterministic thinking in genetics, as historically observed in the justification of eugenics movements and, more recently, in cases of racially motivated violence.
First DNA study of ancient Eastern Arabians reveals malaria adaptation
People living in ancient Eastern Arabia appear to have developed resistance to malaria following the appearance of agriculture in the region around five thousand years ago.
