Climate change and atmospheric dynamics unveil future weather extremes
From late June to mid-July of 2021, the Pacific Northwest was scorched under an unprecedented heat dome, shattering temperature records and igniting a wave of concern over climate extremes. As cities like Portland and Seattle, known for their mild su.....»»
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.....»»
Unveiling sodium channel dynamics: New insights into cell biology using high-speed atomic force microscopy
The transport of ions to and from a cell is controlled by pore-forming proteins embedded in the cell membrane. In particular, voltage-gated sodium channels (VGSCs) govern the transfer of sodium (Na+) ions, and play an important role in the regulation.....»»
Helium is essential for research, medical equipment, but it"s nonrenewable and difficult to recycle
The next time you pick up balloons for your big party, remember the helium gas in those balloons is destined for the stars. Helium is so light that it easily escapes Earth's gravity, and all helium will eventually make its way into space. Like fossil.....»»
New tomographic reconstruction algorithm sets world record
Advanced synchrotron tomography is a critical research tool, allowing scientists to explore the intricate structures of objects in extremely high resolution. Because this technique enables researchers to capture dynamics in real-time, it can capture.....»»
Illuminating plant water dynamics: The role of light in leaf hydraulic regulation
A recent study led by Prof. Menachem Moshelion from The Robert H. Smith Faculty of Agriculture, Food and Environment at The Hebrew University, along with Dr. Yael Grunwald and Dr. Adi Yaara from the same institute, has unveiled the intricate relation.....»»
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.....»»
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.....»»
