All wound up: A reversible molecular whirligig
Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, which is important when u.....»»
Newly discovered bacterial defense system functions as self-destruct button
Wageningen researchers have discovered a molecular self-destruct mechanism in a bacterium living on seaweed. With this mechanism the bacteria sacrifice themselves when they are infected, thus protecting their brothers and sisters from infections. By.....»»
Important molecular pathway for control of aging discovered
One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) in Brazil found that when t.....»»
Case study: The evolution of a series of participant-centered workshops
Ludmila Tyler, senior lecturer in the biochemistry and molecular biology (BMB) department, is co-first author of a paper in the journal Biochemistry and Molecular Biology Education that reflects on the lessons learned from the first full year of Incl.....»»
Microscopy method overcomes the traditional resolution limit for the fast co-tracking of molecules
Researchers at Ludwig Maximilian University (LMU) have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale......»»
Chemists create an emission molecular thermometer
Future technologies rely on phenomena that were previously considered the exclusive domain of theoretical physics or chemistry. For example, the approach to devices with high-density information storage arose when chemists discovered single-molecule.....»»
Light duty: Distinct molecular pathways control growth, flowering in plants
It's well known that plants have a fine-tuned ability to sense changes in the season by how much daylight they're exposed to, yet scientists observed more than a century ago that plants sometimes grow during one season and flower in another. Most res.....»»
Pioneering technique reveals new layer of human gene regulation
A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows......»»
Scientists develop new molecular system made from abundant element manganese for photooxidation
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All.....»»
Examining how molecular orbitals determine stability
Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combinat.....»»
How molecular systems at the origin of life may have evolved: Rise of the nanomachines
By attaching molecules together, scientists at Université de Montréal think they've found how molecular systems at the origin of life evolved to create complex self-regulating functions......»»
Research team identifies new approach to tackling bacterial infections
Researchers at the Icahn School of Medicine at Mount Sinai have identified a new approach to controlling bacterial infections. The findings are described in Nature Structural & Molecular Biology......»»
Researchers discover key to molecular mystery of how plants respond to changing conditions
A team of researchers from the University of Massachusetts Amherst recently published a pioneering study that answers a central question in biology: How do organisms rally a wide range of cellular processes when they encounter a change—either inter.....»»
Decoding the molecular networks of early human development
New international research shines a light on the role of transcription factors during early embryonic development. Transcription factors are proteins that are critical for gene regulation. The study unveiled more than 1,000 protein–protein interact.....»»
Improving accuracy of molecular quantification in high throughput sequencing
A team at NDORMS has developed a new approach to significantly improve the accuracy of RNA sequencing. They have pinpointed the primary source of inaccurate quantification in both short and long-read RNA sequencing, and have introduced the concept of.....»»
Team discovers mechanism that protects tissue after faulty gene expression
A study at the University of Cologne's CECAD Cluster of Excellence in Aging Research has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead.....»»
A type of plastic that can be shape-shifted using tempering
A team of molecular engineers have developed a type of plastic that can be shape-shifted using tempering. In their paper published in the journal Science the team, from the University of Chicago, with a colleagues from the US DEVCOM Army Research Lab.....»»
ALMA spots the shadow of a molecular outflow from a quasar when the universe was less than 1 billion years old
Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the universe was less than a billion years old......»»
Unveiling and decoding the regulatory mechanisms of secondary cell wall formation
Wood quality is primarily determined by the properties of its secondary cell wall (SCW). Gaining insight into the molecular processes governing SCW development is crucial for the genetic enhancement of wood quality. Although it's established that a m.....»»
Researchers discover molecular mechanism that influences the symmetrical shape of the style
Humans are attracted to symmetry: in our buildings, our gardens, in our potential partners. For plants, the symmetrical shapes of organs are a matter of survival because the form directly impacts the function......»»
Molecular simulation AI tool reveals unresolved structure of transporter protein
In a groundbreaking study, researchers have unveiled a previously unknown conformational state of a crucial transporter protein, OxlT, which plays a vital role in preventing kidney stone formation. This discovery, achieved through advanced computatio.....»»
