Scientists develop method "tetraplex digital PCR assay" for detecting DNA of invasive snakes in Florida
Scientists at the University of Florida have developed a pioneering tool to bolster Florida's defenses against invasive species: a DNA-based environmental monitoring test that can pinpoint where they've been, aiding eradication efforts......»»
New technique points to unexpected uses for snoRNA across many cell types
Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence cellular processes, disease development, and overall organismal health. Small nucleolar RNAs (snoRNAs) are a common but overlooked.....»»
Discovery of van Hove singularities could lead to novel materials with desirable quantum properties
Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the van Hove singularity. These interactions give rise to unusual properties in quantum materials, such as superconductivity at hig.....»»
tRNAs help some mRNAs get lost in translation
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein can be made. They publis.....»»
"Genetic time machine" reveals complex chimpanzee cultures
In recent decades, scientists have clearly demonstrated that chimpanzees, like humans, pass on complex cultures such as tool use from generation to generation. But human culture has become vastly more sophisticated, from the Stone Age to the Space Ag.....»»
Study reveals RNA"s unknown role in DNA damage repair
A multi-institutional team of researchers, led by Georgia Tech's Francesca Storici, has discovered a previously unknown role for RNA. Their insights could lead to improved treatments for diseases like cancer and neurodegenerative disorders while chan.....»»
Video: Our sun is the star in a new simulation
NASA supercomputers are shedding light on what causes some of the sun's most complex behaviors. Using data from the suite of active sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar d.....»»
Origin of life research finds RNA can favor both left- and right-handed proteins
The mystery of why life uses molecules with specific orientations has deepened with a discovery that RNA—a key molecule thought to have potentially held the instructions for life before DNA emerged—can favor making the building blocks of proteins.....»»
Using gas bubbles to precisely deliver nanomedicines shows promise for lung cancer treatment
The delivery of nanomedicines using gas bubbles has shown itself to be a unique way of transporting cytotoxins to the lungs of cancer patients. The method enables precise and focused treatments, and the local action of the drugs also prevents a range.....»»
Transparent worms with glowing proteins may help fertility treatments
The development of maternal egg cells is pivotal for survival—but also precarious. During meiosis, the DNA-containing chromosomes can easily be broken or lost, causing infertility, miscarriage or genetic disorders like Down syndrome. Scientists hav.....»»
DNA-based methods found highly effective for identifying insect species
A team of researchers from Linnaeus University and Linköping University, extensively evaluated DNA barcoding and metabarcoding methods. A comprehensive study has demonstrated that DNA-based methods are remarkably reliable for identifying insect spec.....»»
New structure gives insight into mRNA export and cancers, and how viruses hijack the process to infect their host
The central dogma of biology defines the flow of genetic information: It describes how proteins are made from mRNA templates, which are in turn made from DNA. Exporting the mRNA from inside the nucleus to the site of protein translation in the cytopl.....»»
Spatial interactomics tool maps protein interactions to fight lung cancer
As Ahmet F. Coskun and his team of researchers continue their mission to create a 3D atlas of the human body, mapping cells and tissues, they're making discoveries that could lead to better treatments for the most common type of lung cancer......»»
Social media has complex effects on adolescent well-being, and policymakers must take note
In late 2024, more than 20 years after the birth of Facebook, the impact of social media on our lives cannot be overstated. Initially underestimated by many in business, social media eventually came to be recognized for its power to enable workers to.....»»
DNA repair by cooperation between proteins: A look inside the cell"s repair hub
New research from the Kind Group at the Hubrecht Institute sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells......»»
Low-cost phenotyping system unveils key insights into quantitative disease resistance in wild tomatoes
Quantitative disease resistance (QDR) is a complex but durable form of plant disease resistance that provides partial protection against a broad range of pathogens. Unlike qualitative resistance, driven by major resistance (R) genes, QDR is polygenic.....»»
Sugar-like nanoparticle covering could boost cancer drug delivery
A spoonful of sugar might actually help medicine go down, according to recent research from the University of Mississippi. And it could reduce the harmful side effects of cancer treatment. Instead of a literal spoonful of sugar, however, the research.....»»
Megapixel fluorescence microscopy through scattering layers made simple
A team from The Hebrew University of Jerusalem has introduced a new method for megapixel-scale fluorescence microscopy through complex scattering media. This approach resolves high-resolution images from several tens of widefield fluorescence-microsc.....»»
Study reveals how caregiving for loved ones shapes lives of Cleveland"s chronically homeless
Shortly after Jerome's mother died of cancer, he experienced what he described as a "mental breakdown" and, before too long, found himself without a home. Taking care of his mother had drained him—both emotionally and financially......»»
Nanofibers made of copper-binding peptides disrupt cancer cells
