Tiny worm, giant leap: Discovery of highly specific fatty acid attachment to proteins
In a world where the intricacies of molecular biology often seem as vast and mysterious as the cosmos, a new study delves into the microscopic universe of proteins, unveiling a fascinating aspect of their existence. This revelation could hold profoun.....»»
Scientists spin naturalistic silk from artificial spider gland
Researchers have succeeded in creating a device that spins artificial spider silk that closely matches what spiders naturally produce. The artificial silk gland was able to re-create the complex molecular structure of silk by mimicking the various ch.....»»
Clutch-stack-driven molecular gears in crystals could propel material innovation
Gears are an essential component of everyday machines. The ability to shift gears, like in a car, allows for control of the degree or direction of motion generated, making machines more versatile......»»
Unraveling the health benefits of tomatoes: A molecular dive
Scientists at U.S. the Department of Agriculture's Agricultural Research Service (ARS) and The Ohio State University (OSU) have been working to investigate how tomatoes may be imparting health benefits in a recently published study......»»
Researchers observe how the flexibility of a protein hinge is crucial to the transfer of cell proteins
Ubiquitination—the addition of the protein ubiquitin—is a key stage in many cell processes, such as protein degradation, DNA repairs, and signal transduction. Using high-speed atomic force microscopy (HS-AFM) and molecular modeling, researchers l.....»»
Molecular sensor enables water bear hardiness by triggering dormancy, study finds
Tardigrades—hardy, microscopic animals commonly known as "water bears"—use a molecular sensor that detects harmful conditions in their environment, telling them when to go dormant and when to resume normal life. A team led by Derrick R. J. Kollin.....»»
Unraveling the role of supersulfides in regulating mitochondrial function and longevity
Supersulfides are gaining prominence for their occurrence as low-molecular-weight thiols or persulfidated cysteine residues, observed more frequently in both prokaryotic and eukaryotic cells. These compounds, which are characterized by sulfur–sulfu.....»»
ALMA observations show how double, triple, quadruple and quintuple star systems form simultaneously in a molecular cloud
For humans, the chance of giving birth to multiples is less than 2%. The situation is different with stars, especially with particularly heavy stars. Astronomers observe stars that are many times heavier than the sun in more than 80% of cases in doub.....»»
Research team develops anti-icing film that only requires sunlight
A KAIST research team has developed an anti-icing and de-icing film coating technology that can apply the photothermal effect of gold nanoparticles to industrial sites without the need for heating wires, periodic spray or oil coating of anti-freeze s.....»»
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.....»»
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.....»»
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.....»»
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).....»»
