A new mechanism for shaping animal tissues
A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams from the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden, Germany, the Exce.....»»
The molecular shield: How tea plants combat drought through protein phosphorylation
Drought stress poses a significant challenge to agriculture, causing substantial yield losses in many crops. Tea plants, known for their rich flavonoid content which enhances both quality and health benefits, are particularly affected. Under drought.....»»
Study reveals how intermittent fasting regulates aging through autophagy
Recent research at the Institute of Molecular Biology and Biotechnology (IMBB) of the Foundation for Research and Technology-Hellas (FORTH), at the Paris Cité University, and at the University of Graz, published today in Nature Cell Biology, sheds l.....»»
Chemists develop new sustainable reaction for creating unique molecular building blocks
Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers ha.....»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
High nitrogen input promotes the redistribution of new organic carbon to deeper soil layers
Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems. Most current research on soil organic carbon (SOC) dynamics in relation to nitrogen input has focused predominantly on the surface soil layers. How.....»»
Heat stress survival: Unraveling the HsfA2-ACTIN dynamics in lily varieties
A research team has identified that the heat stress transcription factor HsfA2 and actin-interacting protein (AIP) LACTIN interact at the protein level in Lilium longiflorum "White Heaven," mediating gene expression and protecting cells from heat str.....»»
Breakthrough in molecular control: New bioinspired double helix with switchable chirality
The deoxyribonucleic acid or DNA, the molecular system that carries the genetic information of living organisms, can transcribe and amplify information using its two helical strands. Creating such artificial molecular systems that match or surpass DN.....»»
New computer vision-based system monitors seasonal dynamics of tropical water
Understanding how water moves and changes around the world is more important than ever due to climate change, but monitoring inland water in the tropics is not easy. Most satellites are optical and simply take photos of surfaces. They cannot see thro.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Disparity dynamics: Geographic impact of social transfer programs on income inequality
Social transfer programs have significant geographic differences in spending that help to reduce income gaps between rich and poor regions of the United States, according to new University of Michigan research......»»
Invasive insect herbivore alters ecosystem services delivered by cycads
A study published in the June 2024 issue of the journal Pedosphere looks at how a non-native armored scale insect alters the leaf litter decomposition dynamics of the novel host cycad species on newly invaded islands. The scale insect, known as cycad.....»»
Nanoscale imaging provides insights into 2D and phase-change materials
Researchers from the University of California, Berkeley have developed cutting-edge nanoscale optical imaging techniques to provide unprecedented insights into the ultrafast carrier dynamics in advanced materials......»»
Scientists identify the predictability limit of oceanic mesoscale eddy tracks in the South China Sea
Oceanic mesoscale eddies (OMEs) are swirling water structures that play a crucial role in ocean dynamics. These eddies transport heat, salt, nutrients, and other materials across the ocean, significantly influencing marine ecosystems and global clima.....»»
Boeing says Starliner hot fire test on ISS went well with return date decision coming up
As Boeing's Starliner nears two months in space, teams performed a hot fire test of thruster performance and helium leaks on the spacecraft over the weekend to help inform the decision of when the spacecraft will come home and if its two NASA astrona.....»»
New research offers insight on modeling belief dynamics
Researchers who study belief dynamics often use analogies to understand and model the complex cognitive–social systems that underlie why we believe the things we do and how those beliefs can change over time. Ideas can be transmitted like a virus,.....»»
