Exploring molecular boundaries in DNA
It's important to be well organized. And this is especially true for the genome—the entirety of an organism's genetic information, also known as DNA. The genomic DNA is several meters long but has to fit inside the cell's nucleus, which has a diame.....»»
Cryo-microscopy reveals nano-sized copy machine implicated in origin of life
How the intricate molecular machinery of life arose from simple beginnings has been a long-standing question. Several lines of evidence point towards a primordial "RNA world," where an "RNA copy machine" (a so-called replicase) started making copies.....»»
Exploring the integration of crops and livestock in different historical contexts from ancient times to the present
Crop–livestock integration, the practice of combining crop planting and livestock breeding, is recognized as a fundamental approach to fostering a circular and green economy in agriculture......»»
How to use the Command Prompt in Windows 10 and 11
The Windows Command Prompt might be old, but it's still a useful tool for tweaking, diagnosing, and exploring your Windows 10 or 11 PC. Here's how to use it......»»
Researchers develop technique to synthesize water-soluble alloy nanoclusters
In recent years, ultrasmall metal nanoclusters have unlocked advances in fields ranging from bioimaging and biosensing to biotherapy, thanks to their unique molecular-like properties......»»
Efficient antibody production "wobbles," new study finds
Molecular biology's central dogma posits a simple recipe for the construction of the human body: a DNA blueprint is transcribed into an RNA message, and the RNA message is translated into the proteins that make you. Translating the mRNA message is a.....»»
Exploring common types of feline mange
Mange is a skin disease that can compromise a pet's well-being, leading to discomfort and potential health complications. Though it is a more common condition for dogs, cats can also be at risk, which is why owners should familiarize themselves with.....»»
Methane activation by [LnO]+: The 4f orbital matters
As the "holy grail" in the field of chemistry, the catalytic activation of methane has been a topic of great interest in the field of heterogeneous catalysis. Gas-phase experiments provide an ideal platform for exploring catalytic reaction mechanisms.....»»
A new type of plant metalloreductase maintains root growth under low phosphorus
The release of low-molecular weight carboxylates, such as malate, is used by many plant species to mine poorly available phosphorus (P) from the soil. Malate can increase the availability of phosphate, the P form taken up by plants, by chelating triv.....»»
A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular me.....»»
Research team reports observing vibrational spectra of a single protein with infrared nanospectroscopy
An interdisciplinary research team, led by Assistant Prof. Jun Nishida and Associate Prof. Takashi Kumagai at the Institute for Molecular Science, has successfully observed vibrational spectra of single proteins, consisting of approximately 500 amino.....»»
Top LLM vulnerabilities and how to mitigate the associated risk
As large language models (LLMs) become more prevalent, a comprehensive understanding of the LLM threat landscape remains elusive. But this uncertainty doesn’t mean progress should grind to a halt: Exploring AI is essential to staying competitive, m.....»»
Study reveals key molecular mechanisms involved in development of tomato plant
In an article published in the journal Development, researchers at the University of São Paulo's Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil describe mechanisms relating to the development of the tomato plant (Solanum lycopersicum).....»»
Exploring developments and challenges in electrochemical nitrate reduction for ammonia synthesis
Ammonia is a necessary feedstock to produce nitrogen-based fertilizers, chemicals, pharmaceuticals, and polymers. To date, about 80% of global ammonia is used to produce nitrogen-based fertilizers which relates to 50% of global food production......»»
Quantum energy exchange: Exploring light fields and a quantum emitter
A new study in Physical Review Letters illuminates the intricacies of energy exchanges within bipartite quantum systems, offering profound insights into quantum coherence, pure dephasing effects, and the potential impact on future quantum technologie.....»»
Researchers discover molecular "barcode" used by bacteria to secrete toxins
Researchers at McMaster University have discovered a molecular "barcode" system used by disease-causing bacteria to distinguish between beneficial and toxic molecules......»»
Protein structures signal fresh targets for anticancer drugs
Cell replication in our bodies is triggered by a cascade of molecular signals transmitted between proteins. Compounds that block these signals when they run amok show potential as cancer drugs......»»
Exploring dimensions of justice in climate science
How can climate policy be made more just and fair? IIASA researchers have synthesized different dimensions of justice into a framework that can be used by climate scientists and policymakers, explaining how previous research has neglected many potent.....»»
Exploring how antibiotic-resistant bacteria become aggressive
Some strains of antibiotic-resistant bacteria that have recently acquired disease-enhancing genes may not behave as aggressively as expected, according to a Northwestern Medicine study recently published in Nature Communications......»»
Even far below freezing, ice"s surface begins melting as temperatures rise
Physics is filled with mysteries. To find a few worth exploring, look no further than an ice cube. At room temperature, of course, the cube will melt before your eyes. But even far below freezing, ice can shift in barely perceptible ways that scienti.....»»
Pathogenic bacteria use molecular "shuttle services" to fill their injection apparatus with the right product
