In February 2024, a research article titled "Pumpkin CmoDREB2A enhances salt tolerance of grafted cucumber through interaction with CmoNAC1 to regulate H2O2 and ABA signaling and K+/Na+ homeostasis" was published by Professor Zhilong Bie's team from.....»»
Mechanism of grafting Prunus sp. to control crown gall disease by regulating the rhizosphere environment
Grafting is a traditional and significant strategy to suppress soil-borne diseases, such as the crown gall disease caused by tumorigenic Agrobacterium and Rhizobium. Root exudates and the rhizosphere microbiome play critical roles in controlling crow.....»»
Researchers discover mechanism regulating bud dormancy release in tree peony
In perennial woody plants, bud endodormancy is crucial for survival under adverse environmental conditions in winter, such as low temperature (LT) and dehydration stress. To break bud dormancy is essential for the resumption of bud growth and floweri.....»»
Supercomputer simulation reveals new mechanism for membrane fusion
An intricate simulation performed by UT Southwestern Medical Center researchers using one of the world's most powerful supercomputers sheds new light on how proteins called SNAREs cause biological membranes to fuse......»»
"Forgotten city:" the identification of Dura-Europos" neglected sister site in Syria
The Dura-Europos site in modern-day Syria is famous for its exceptional state of preservation. Like Pompeii, this ancient city has yielded many great discoveries, and serves as a window into the world of the ancient Hellenistic, Parthian, and Roman p.....»»
Key protein regulates immune response to viruses in mammal cells
Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and.....»»
Studying spaceflight atrophy with machine learning
Even intense exercise by astronauts cannot compensate for muscle atrophy caused by microgravity. Atrophy occurs, in part, by way of an underlying mechanism that regulates calcium uptake. Recent research has shown exposure to spaceflight alters the up.....»»
Researchers uncover human DNA repair by nuclear metamorphosis
Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging......»»
New time-resolved ultraviolet photodissociation mass spectrometry strategy for target protein stability analysis
How mutations impact protein stability and structure dynamics is crucial for understanding the molecular mechanism of the disease and the targeted drug design. However, probing the molecular details of mutation-induced subtle structure dynamics is st.....»»
Ocean currents threaten to collapse Antarctic ice shelves, study finds
A new study published in Nature Communications has revealed that the interplay between meandering ocean currents and the ocean floor induces upwelling velocity, transporting warm water to shallower depths. This mechanism contributes substantially to.....»»
New NASA strategy envisions sustainable future for space operations
To address a rapidly changing space operating environment and ensure its preservation for generations to come, NASA released the first part of its integrated Space Sustainability Strategy, on Tuesday advancing the agency's role as a global leader on.....»»
Researchers develop mechanism of electrical 180° switching of Néel vector in spin-splitting antiferromagnet
A research team led by The Hong Kong University of Science and Technology (HKUST) and Tsinghua University has theoretically proposed a new mechanism of electrical 180° switching of Néel vector and experimentally realized it in antiferromagnetic mat.....»»
Scientists discover new phage resistance mechanism in phage-bacterial arms race
One of the most abundant and deadliest organisms on Earth is a virus called a bacteriophage (phage). These predators have lethal precision against their targets—not humans, but bacteria. Different phages have evolved to target different bacteria an.....»»
Researchers map structure of mitochondria at different life stages
Mitochondria, organelles with an inner and outer membrane, are responsible for creating the energy that cells use to survive, and their morphology is key to accomplishing this task. The inner mitochondrial membrane contains folds, called cristae, tha.....»»
Chinese scientists reveal the spinning mechanism of the silkworm
