Chemists develop chiral DNA catalysts for asymmetric catalysis
Chemists from the National University of Singapore (NUS) have developed a way to make diverse chiral deoxyribonucleic acid (DNA) catalysts by merging DNA repair with biorthogonal chemistry, paving the way for more efficient and versatile approaches t.....»»
Time is running out for a treaty to end plastic pollution—here"s why it matters
On March 2, 2022, delegates to the UN environment assembly adopted an ambitious resolution to develop the text of a new treaty by the end of 2024 to end plastic pollution. With 24 days of formal negotiation between almost 200 countries completed, spr.....»»
Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they.....»»
"e-Drive": New gene drive reverses insecticide resistance in pests... then disappears
Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ineffective......»»
Researchers develop miRNA-tunable living interface for neurovascular remodeling
A research team led by Dr. Du Xuemin from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has reported a living interface with unique functionalities of durable secretion of bioactive exosomes with tunable con.....»»
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.....»»
Scientists develop novel high-fidelity quantum computing gate
Researchers from the RIKEN Center for Quantum Computing and Toshiba have succeeded in building a quantum computer gate based on a double-transmon coupler (DTC), which had been proposed theoretically as a device that could significantly enhance the fi.....»»
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.....»»
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.....»»
Establishing a general theory of metal-support interaction: AI-driven advances in catalysis
How can artificial intelligence (AI) help accelerate scientific discovery based on vast amounts of experimental data? A new study by Prof. Li Weixue's team from the University of Science and Technology of China (USTC) of the Chinese Academy of Scienc.....»»
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.....»»
Chemists create world"s thinnest spaghetti
The world's thinnest spaghetti, about 200 times thinner than a human hair, has been created by a UCL-led research team. The spaghetti is not intended to be a new food but was created because of the wide-ranging uses that extremely thin strands of mat.....»»
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......»»
Scientists develop culture system to unlock secrets of the skin microbiome
The human skin is home to a wide variety of bacteria. The composition of the community of bacteria—called the "skin microbiota"—has serious implications for skin health. A healthy balance between different species of bacteria on the skin often tr.....»»
Turning carbon emissions into methane fuel: New method offers potential for abundant energy savings
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources......»»
Researchers develop pioneering monitoring technique to help build mangrove resilience
Mangroves are remarkable ecosystems home to amazing biodiversity, dense vegetation, and conditions that capture large quantities of carbon. Since they occur in warm, tropical, and subtropical coastal regions, they also take the brunt of the impact fr.....»»
From Houston to the moon: Johnson"s thermal vacuum chamber tests lunar solar technology
