Sugar signaling is one of the most important regulatory signals for plant growth and development, and its metabolic network contains many regulatory factors. Sugar signaling molecules regulate cellular activities and organismal development by interacting with other intrinsic regulators and environmental cues. HXK, SnRK1 and TOR are three proteins that play key roles in the plant sugar metabolism network.

Capacitors are crucial components in electronic devices such as smartphones and computers. They are made of dielectric materials that polarize on the application of the voltage. Currently, barium titanate (BaTiO3) is the most widely used material for capacitors.

The loss of your job can be as devastating emotionally as a divorce. It's true that a divorce can actually enhance your marriage skills for the next time around, since the skills needed remain virtually unchanged, but the same cannot be said for job-loss situations.

Thermal barrier coatings (TBCs) are widely used in gas turbine engines to obtain elevated working temperatures and improve engine efficiency. The phase transition of the ceramic layer is accompanied by a large volume difference, causing the concentration of thermal stress, eventually leading the TBCs to fall off and fail. Therefore, it is necessary to quantitatively evaluate the magnitude and distribution of thermal stress induced by phase transition in the ceramic layer.

In a paper published in Science Bulletin, a Chinese team of scientists predicts a novel electride K(NH3)2, with interstitial electrons distributed at cages formed by six ammonia molecules and forming a quasi-2D triangular lattice. They have revealed that this material undergoes a spin-Peierls phase transition under moderate pressures.

The antimicrobial potential of CRISPR-Cas systems is promising, yet how to best design or implement CRISPR nucleases remains poorly understood. An international team led by the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg has now addressed this knowledge gap.

Finding a convincing explanation of a complex issue is no easy task. The decision about what qualifies as the "best" solution is inevitably subject to biases and approximations. Coupling statistics with historical methods, however, makes the decision process more rigorous and less error-prone.

People who speak a regional dialect or who have an accent may be at a disadvantage in personnel selection processes. This is the result of a new meta-analysis carried out by researchers at Freie Universität Berlin, the Neu-Ulm University of Applied Sciences, and Ulm University.

Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be missing in terrestrial carbon cycle simulations.

In the ongoing quest to track the progression of climate change, scientists frequently examine the state of our planet's vegetation—forests, grasslands, agricultural lands, and beyond.

It's been five years since Canada stepped into the forefront of cannabis legalization, setting a significant precedent in the realm of drug policy. With Canada and 24 US states now embracing recreational cannabis, the battle against the illegal market remains a key concern, one highlighted in the federal government's final report on the Cannabis Act.

New University of Minnesota research suggests "leaf glow" provides vital information on vegetation dynamics in Arctic and boreal ecosystems like Minnesota's forests and wetlands, which are among the fastest warming in the world. Using remote sensing to monitor the natural glow may help scientists better track climate change and its impact on our natural resources.

Language skills are one of the key factors to explain residential segregation and play an important role in understanding immigrant residential environments, new research from the University of Aberdeen has found.

Several years ago, a team of scientists from MIT and the University of Massachusetts at Lowell designed and deployed a first-of-its-kind web programming course for incarcerated individuals across multiple correctional facilities. The program, Brave Behind Bars, uses virtual classroom technology to deliver web design training to students behind prison walls.

Educational damage from the COVID-19 pandemic will have an impact on school pupils well into the 2030s, according to a study involving the University of Strathclyde.

Just as water moves through a river, rivers themselves move across the landscape. They carve valleys and canyons, create floodplains and deltas, and transport sediment from the uplands to the ocean.

Following the 2017 siege of Marawi, the Philippines' counter-terrorism efforts have faced an increasingly complex and unpredictable landscape. While authorities have claimed victory, one which garnered global media attention during the peak of ISIS reign in Syria and Iraq, the aftermath of Marawi highlights the urgent need for a comprehensive reassessment of the country's counter-terrorism strategy.

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 the National Key Laboratory for Germplasm Innovation & Utilization of Horticultural Crops/College of Horticulture and Forestry Sciences at Huazhong Agricultural University and the Hubei Hongshan Laboratory, in Horticulture Research.

In recent years, the scientific community has increasingly turned its attention to sustainable agriculture, aiming to maximize crop yield while minimizing environmental impact. A crucial aspect of this research involves understanding the fundamental processes of plant photosynthesis and how they can be monitored at scale.

Champagne corks popped on December 3, 1989 as Soviet leader Mikhail Gorbachev and US president George H.W. Bush met on the cruise ship, Maxim Gorky, off the coast of Malta to declare the end of the cold war.

In a new Journal of Dairy Science study, researchers have increased the quantity and quality of the available data on genetic traits related to feed efficiency and methane emissions

The financial crisis of 2008 showed just how much the world depends on banks being well run. Since then, regulators have been given new powers to keep some of the biggest institutions on a much shorter leash to stamp out risk, greed and corruption.

Understanding why some people trust some scientists more than others is a key factor in solving social problems with science. But little was known about the trust levels across the diverse range of scientific fields and perspectives.

A study published April 25, in the journal Science provides the strongest evidence to date that not only is nature conservation successful, but that scaling conservation interventions up would be transformational for halting and reversing biodiversity loss—a crisis that can lead to ecosystem collapses and a planet less able to support life—and reducing the effects of climate change.

Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study published in Science. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century.
