Online brand advocacy and Gen Z consumer behavior

Understanding the dynamics of online brand advocacy is increasingly important in today's digital landscape, particularly for businesses targeting Generation Z (Gen Z) consumers. A study in the International Journal of Internet Marketing and Advertising surveyed 221 students intending to explore the factors influencing online brand advocacy behavior and its impact on purchase intentions and also...

How to build your own robot friend: Making AI education more accessible

From smart virtual assistants and self-driving cars to digital health and fraud prevention systems, AI technology is transforming almost every aspect of our daily lives—and education is no different. For all its promise, the rise of AI, like any new technology, raises some pressing ethical and equity questions.

Generative AI can accelerate study time, research shows

Time plays a crucial role in higher education learning and influences learning progress and the achievement of academic goals. Shortening learning time through AI-supported, personalized approaches can help to reduce drop-out rates and increase enrollment rates.

Assessing soil carbon stocks accurately

Researchers from Teagasc have published an article in Geoderma Regional highlighting the consequences of not measuring soil organic carbon (SOC) stocks in Irish grassland soils precisely. Quantifying changes in SOC, either carbon sequestration or losses into the atmosphere, requires accurate determination of soil bulk density, which is only achieved by accounting for soil stone content (rock...

Solar physics: Why study it? What can it teach us about finding life beyond Earth?

Universe Today has investigated the importance of studying impact craters, planetary surfaces, exoplanets, and astrobiology, and what these disciplines can teach both researchers and the public about finding life beyond Earth. Here, we will discuss the fascinating field of solar physics (also called heliophysics), including why scientists study it, the benefits and challenges of studying it, what...

Big lemming populations are important for far more than just predators

The number of lemmings (Lemmus lemmus) in the mountains can fluctuate sharply from one year to the next. Years when populations explode are called lemming years. These population explosions are important for many other species. More predators and birds of prey, for example, do better and often have more offspring than usual when there are plenty of lemmings around.

Research provides insight into constructing gene regulatory networks

Gene regulatory networks (GRNs) depict the regulatory mechanisms of genes within cellular systems as a network, offering vital insights for understanding cell processes and molecular interactions that determine cellular phenotypes. Transcriptional regulation, a prevalent type for regulating gene expression, involves the control of target genes (TGs) by transcription factors (TFs).

Disentangling nature's contributions to international trade

Researchers have developed a multistep process to quantify the dependency of international trade and nature's contributions to people. With their new approach, which has been published in People and Nature, the researchers hope to improve knowledge about the complex relationship between nature and international trade.

Altering the circadian clock adapts barley to short growing seasons

To ensure that plants flower at the right time of year, they possess an internal clock that enables them to measure the amount of daylight during a day. In a study published in the journal Plant Physiology, biologists from Heinrich Heine University Düsseldorf (HHU) describe that the mutation of a specific gene makes the flowering time of barley almost entirely independent of day length. This...

Biomolecular condensates: Regulatory hubs for plant iron supply

Iron is a micronutrient for plants. Biologists from the Institute of Botany at Heinrich Heine University Düsseldorf (HHU) describe in a study, which has now been published in the Journal of Cell Biology, that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light—an important signal for plant growth. They found that the...

Using light to control the catalytic process

Nature is amazing. It has developed in living organisms the ability to regulate complex biochemical processes with remarkable efficiency. Enzymes, natural catalysts, play a pivotal role in this regulation, ensuring the fulfillment of various physiological needs throughout a cell's lifespan.

Super strong magnetic fields leave imprint on nuclear matter

A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe's most powerful magnetic fields on "deconfined" nuclear matter. The evidence comes from measuring the way differently charged particles...

How people get sucked into misinformation rabbit holes, and how to get them out

As misinformation and radicalization rise, it's tempting to look for something to blame: the internet, social media personalities, sensationalized political campaigns, religion, or conspiracy theories. And once we've settled on a cause, solutions usually follow: do more fact-checking, regulate advertising, ban YouTubers deemed to have "gone too far."

Strategic grazing could boost conservation of 'near-threatened' sage-grouse

A multi-agency study, spearheaded by researchers from the University of Nevada, Reno's College of Agriculture, Biotechnology & Natural Resources and the U.S. Department of Agriculture, underscores the impacts of strategic cattle grazing, particularly on restoring the declining population of the greater sage-grouse bird, a keystone species in the Great Basin region.
