Study of wild type mosquitoes in Burkina Faso discovers new signs of insecticide resistance
One of the main discoveries of a new study is the identification of new variants in genes associated with insecticide resistance in Anopheles mosquitoes, the primary vectors of malaria in West Africa, and potential novel resistance mechanisms, emphas.....»»
DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation
Tracy Rittenhouse, associate professor of natural resources and the environment in UConn's College of Agriculture, Health and Natural Resources (CAHNR), was doing an experiment to study ranavirus epidemics in wood frogs. When Meghan Parsley, then a P.....»»
Protein signaling pathway provides insights into cell migration and cancer metastasis
The innate immune response is the body's first line of defense against infection, and a successful immune defense takes a village: a combination of physical barriers, chemical attacks, and an army of specialized white blood cells. But maintaining and.....»»
Cryo-electron microscopy sheds light on endothelin signaling mechanisms
Endothelin is a peptide hormone known for its vasoconstrictive effects. Researchers at University of Tsukuba used cryo-electron microscopy to examine the complex structure of the endothelin receptor and G protein, which are crucial for signal transdu.....»»
The role of compromised cyber-physical devices in modern cyberattacks
Cyber-physical devices are increasingly getting compromised and leveraged by criminal groups and state-sponsored threat actors. Fyodor Yarochkin, Senior Threat Solution Architect with Trend Micro, believes that getting a better understanding of attac.....»»
DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»

First mRNA stabilizing substance could aid in development of innovative mRNA therapeutics
Messenger RNA–based therapeutics and vaccines are the new hope in the fight against incurable diseases. A commonly used strategy in the development of messenger RNA (mRNA) medicine is based on the destruction of disease-causing mRNA. Achieving the.....»»
New theoretical framework sets limits for the realization of quantum processes in spacetime
Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These are principles rooted in Einstein's theory of relati.....»»
Photocatalytic behavior at the air-solid interface offers new insights into environmental remediation
A study led by Dr. Marcelo I. Guzman and his team at the University of Kentucky has unveiled significant advancements in the field of photocatalysis. The research, published in the Journal of Physical Chemistry C, explores the photocatalytic behavior.....»»
Airborne DNA tech transforms endangered wildlife monitoring
University of Queensland researchers have created new tools that could change how conservation experts monitor and protect some of Australia's most endangered species......»»
Scientists discover "selfish DNA" crucial for early human development
A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found......»»
Canopy structure regulates autumn phenology by mediating microclimate in temperate forests, finds study
Autumn phenology serves as a sensitive indicator of temperate forests' response to climate change and is a key factor influencing forest carbon sequestration. Understanding the mechanisms driving the spatiotemporal variations in autumn phenology is c.....»»
Protein USP50 identified as key in DNA replication balance
A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study......»»
Expansion in situ genome sequencing innovation makes hidden DNA-protein interactions visible
Harvard scientists have unveiled a new technique called expansion in situ genome sequencing (ExIGS) that combines existing in situ genome sequencing (IGS) with expansion microscopy (ExM). The innovation allowed researchers to link nucleus abnormaliti.....»»
