Formation of pores in mitochondrial membrane elucidated
Mitochondria are considered to be the power plants of cells and are essential for human metabolism. Dysfunction in 40% of mitochondrial proteins are associated with human diseases, which is why mitochondria also play an important role in medical rese.....»»
Scientists discover nonstomatal control of water loss in critical crops
Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism—tiny pores known as stomata......»»
Scientists discover how TGF-Beta sends its message even while tethered to the cell membrane
For years, scientists have thought that TGF-Beta, a signaling protein that holds sway over an astonishing array of cellular processes from embryonic development to cancer, could only do its work once it escaped a lasso-like "straitjacket.".....»»
Study shows microbial diversity differences in volcanic cones and craters
Volcanic activity alters the Earth's surface and promotes the development of new ecosystems, providing valuable models for studying soil formation processes such as microbial composition and vegetation succession. Increasing evidence suggests that so.....»»
Flowers use adjustable "paint by numbers" petal designs to attract pollinators, researchers discover
Flowers like hibiscus use an invisible blueprint established very early in petal formation that dictates the size of their bullseyes—a crucial pre-pattern that can significantly impact their ability to attract pollinating bees......»»
James Webb trains its sights on the Extreme Outer Galaxy
A gorgeous new image from the James Webb Space Telescope shows a bustling region of star formation at the distant edge of the Milky Way......»»
Discovery about ice layer formation in ice sheets can improve sea level rise predictions
A newly discovered mechanism for the flow and freezing of ice sheet meltwater could improve estimates of sea level rise around the globe......»»
Catalyzing environmental cleanup: A highly active and selective molecular catalyst and electrified membrane
Some chemicals create environmental problems; others, fortunately, can help clean them up. Chemists from Yale University and their colleagues have developed an electrochemical catalyst and membrane that offers an efficient and sustainable way to trea.....»»
Elucidating the mechanism underlying de novo membrane formation during gametogenesis
Researchers at University of Tsukuba have meticulously examined the gametogenesis of budding yeast, a process involving meiosis and spore formation, using live imaging techniques. Their findings reveal that during sporulation, the endoplasmic reticul.....»»
Formation of super-Earths proven limited near metal-poor stars
In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars......»»
Researchers examine protein arrangement in cell membrane that triggers programmed cell death
How can molecular structures be analyzed when the resolution of the techniques available is not sufficient? Researchers from the fields of physics, chemistry and medicine at Heinrich Heine University Düsseldorf (HHU) have combined and further develo.....»»
Uncovering the unique roles of Exportin-5 in RNA export within Drosophila cells
Eukaryotic cells are complex biological units, each with multiple membrane-bound compartments. These cells use specialized mechanisms to export biomolecules from their synthesis site to where they function......»»
Decoding the language of cells with the power of proteomics
Hundreds of millions of years ago, single cells joined forces to become multicellular organisms. At the foundation of this multicellular world is the cell surface: the plasma membrane surrounding each cell, where individual units meet and communicate.....»»
A space oddity—small exoplanet challenges existing theories on planet formation
A research team led by Lund University in Sweden has discovered a small planet that displays peculiar orbital motion. The shimmying planet, located 455 light-years from Earth, shows that planetary systems can be considerably more complex than researc.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
A chloroplast-mimicking nanoreactor for enhanced CO₂ electrocatalysis
Chloroplast, which is a double-membrane-bounded organelle, is the main site for CO2 fixation via photosynthesis in green plants. The double-membrane configuration can regulate the transport of substances into and out of the chloroplasts with the aid.....»»
Hubble traces star formation in nearby nebula NGC 261
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA's Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way's closest galactic com.....»»
Research unravels dual role of membrane protein in rice ethylene signal transduction
A research team, led by Professor Zhang Jinsong from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences, revealed insights into the mechanism by which the membrane protein MHZ3 collaborates with the ethylene.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»
