The researchers liken the internet to a huge marketplace where journalists use headlines to compete for readers’ attention. Attention is a precious commodity in the digital age, as content can be produced more cheaply than ever before—resulting in an oversupply and fierce competition to engage readers’ interest.  

Headlines play a crucial role in drawing readers in. They need to grab attention and arouse curiosity. Unlike print headlines, the success of each individual online headline can be measured in terms of the number of clicks it receives. The researchers argue that this leads to online headlines being worded to generate as many clicks as possible, effectively becoming clickbait.   

“Our analysis shows that the language of online headlines has changed systematically over the years,” says lead author Pietro Nickl, a predoctoral fellow in the Center for Adaptive Rationality at the Max Planck Institute for Human Development. “Many of these changes indicate that they are being adapted to the new affordances and pressures of the digital environment.” 

Online news headlines have changed markedly in the last 20 years  

The analysis focused on linguistic and structural changes in headlines since 2000. These changes reflect not only changes in editorial practice, but also the growing importance of headlines as a key element in the digital competition for attention. Unlike in print journalism, where headlines primarily need to be clear and concise, online headlines are used strategically to generate clicks. Clickbait headlines are characterized by their length: They are written in a conversational tone and serve to arouse curiosity without revealing much information. In fact, the researchers found that the average length of headlines has increased continuously over time. They also observed an increased use of linguistic devices typically associated with clickbait. These include active verbs, the use of pronouns such as “I,” “you,” or “they,” and a higher frequency of question words (“how,” “what,” “why”). These elements arouse curiosity by creating an information gap that readers can only bridge by clicking to open the article. 

Another notable finding concerns sentence structure. While noun phrases such as “Earthquake in Myanmar” were common in the early 2000s, full sentences later became more popular. Full-sentence headlines are more dynamic and emotional, often narrative in structure, and appeal more strongly to the emotions. 

The shift in emotional tone was also striking. Sentiment analysis showed that headlines have become more negative on average, across both high-quality and tabloid journalism. Interestingly, right-wing media outlets used headlines with negative connotations significantly more often than left-wing or politically neutral ones. 

Developments reinforced by algorithms 

“The changes are not the result of individual editorial decisions, but reflect a process of cultural selection. Specific linguistic features prevail because they are more successful under the conditions of the digital attention economy. They are used more and more frequently—sometimes without the people who produce or consume them even being aware of what is happening,” says Pietro Nickl. This whole development is reinforced by social media recommendation algorithms.  

The study is based on data from four international news outlets—The New York TimesThe GuardianThe Times of India, and ABC News Australia—as well as the comprehensive News on the Web corpus (NOW), which contains some 30 million additional headlines from various countries. In addition, data from Upworthy (as a prime example of clickbait style) and from a corpus of scientific preprints (as a counterexample) were analyzed. Over time, the news headlines became increasingly similar to the clickbait titles on most variables considered. Data analysis was conducted using modern natural language processing methods such as sentiment analysis, syntactic analysis, and dictionary-based counting. 

Manipulative content is getting harder to detect  

The results also raise fundamental social questions. The increasing prevalence of clickbait style in traditional media could, in the long term, undermine trust in journalism and make it more difficult to distinguish between reputable and manipulative content. Many linguistic features that were previously red flags for clickbait or manipulative content—such as overly emotional language or heavy use of pronouns and question words—are now also common in quality media. “If the style of established media increasingly resembles that of problematic sources, the boundaries become blurred—which makes it more difficult to distinguish between serious and manipulative content,” warns co-author Philipp-Lorenz Spreen, research scientist in the Center for Adaptive Rationality at the Max Planck Institute for Human Development. 

Need for changes in platform design  

The researchers nevertheless see opportunities for action by shaping the digital information landscape. If metrics such as click-through rates or time on page have adverse effects on content, it is time to think about alternative metrics. The first platforms are already experimenting with new approaches—one emerging metric is “deeply read” content, which focuses on how thoroughly users engage with articles rather than just the number of clicks. In the long term, individually selectable criteria could also help to promote a more diverse and sustainable media landscape. 

In brief: 

  • Online news headlines have become longer and more negative.  
  • They tend to use clickbait style to attract attention. 
  • This development can be observed across news outlets, regardless of journalistic quality.
  • Potential reasons include the sinking production costs of online publications, a general change in style, or the more competitive online environment.

Stroke is a leading cause of mortality and disability globally, with a particularly high prevalence in low- and middle-income countries. In China, the number of stroke survivors is rising due to an ageing population. Post-stroke depression (PSD) is a common neuropsychiatric condition that can severely impact recovery and overall well-being. A recent study published in General Psychiatry sheds light on the prevalence and impact of depression among older stroke survivors in China, aiming to explore the prevalence of PSD and its association with quality of life (QoL).

The study utilized data from the 2017–2018 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), a nationwide community-based project led by Peking University. Researchers analyzed data from 1,123 stroke survivors aged 65 and older. Depressive symptoms were assessed using the 10-item Centre for Epidemiological Studies Depression Scale (CESD), and QoL was measured with the World Health Organization Quality of Life-brief version (WHOQOL-BREF).

Depression is prevalent among older stroke survivors, with 34.3% experiencing depressive symptoms. The most central symptoms identified through network analysis were "feeling blue/depressed", "feeling nervous/fearful", and "loneliness". The study also examined the relationship between specific depressive symptoms and QoL. Symptoms such as "hopelessness", "sleep disturbances", and "everything was an effort" were found to have the strongest negative associations with QoL. Stroke survivors with these symptoms reported significantly lower QoL compared to those without depressive symptoms.

Prof. XIANG Xutao, the corresponding author, emphasized the importance of these findings: "Our study highlights the need for targeted interventions addressing central PSD symptoms to improve depressive symptoms and overall QoL among older stroke survivors."

Additionally, the findings suggest that improving activities of daily living (ADL), reducing anxiety, ensuring sufficient financial support, and promoting regular physical exercise are critical for reducing the risk of PSD.

In conclusion, this study provides valuable insights into the prevalence and impact of PSD among older stroke survivors in China. By identifying central symptoms and their associations with QoL, the research offers a foundation for developing targeted interventions to improve mental health and overall well-being in this vulnerable population.

Over the last decade, various emerging technologies and educational disruption, particularly during the previous global pandemic, have resulted in an increasing gap between emerging economies and the developed world, which represents the third of the “triple disruptions” that are shaping the macro-context of higher education. Under these circumstances, it seems necessary to examine the different types of South-South interactions in higher education in the context of the "triple disruptions", as well as their dynamics and challenges.

In a study published online on May 9, 2025, in ECNU Review of Education, researchers from Zhejiang University, doctoral candidate Jingji Zhang and her doctoral supervisor professor Hantian Wu, attempted to identify the rationale and strategies of different South-South higher education interaction models. Using the conceptual perspectives of Southern epistemologies and the typology of “inward- and outward-oriented” higher education internationalization, the researchers analyzed a range of selected documents, including academic literature, national strategies and legislation, and public reports issued by states, institutions, and other stakeholders that focused on South–South higher education interactions.

The findings suggest that South–South higher education interactions generally occur through a mix of approaches with a preference for inward-oriented expansion diffusion. Given the “triple disruptions,” regional cooperation based on advantages and characteristics remains the most promising form of South–South higher education interactions. Additionally, the notion of new types of colonialism serves as a wake-up call for Southern countries’ outward-oriented HE internationalization through relocation diffusion for soft power enhancement. “It is essential to develop a decolonial approach to digitalization to ensure that the South benefits without losing its autonomy,” argued Zhang and Prof. Wu.

This study contributes to the critical examination of the Western-centric theoretical monopoly on internationalization in higher education by clarifying the principles and positions of South–South higher education cooperation through epistemological exploration. It draws patterns from the complex practices of existing South–South cooperation in higher education based on the typology of “inward- and outward-oriented” higher education internationalization and attempts to provide theoretical contributions in the context of the “triple disruptions.” “A critical methodology is essential for research on higher education internationalization,” as Zhang and Prof. Wu cited the viewpoints of Jooste and Heleta. Theoretical contributions can also be instructive for the practice. Based on the research findings, Zhang and Prof. Wu argued that “countries in the Global South must prioritize identifying a distinct niche and sharpening their institutional profile by realigning existing resources and cooperation strategies.” “This approach can foster mutual benefits, compromise, and understanding, ultimately leading to the development of a more equitable and inclusive global HE system,” they concluded.

How did plants evolve the ability to transport massive amounts of protein into seed vacuoles?



Tracing evolutionary steps through the gradual functional shift of a membrane trafficking protein

How VAMP72 evolved into VAMP727 through stepwise changes in plants 

image: 

This illustration shows how the membrane trafficking protein VAMP72 gradually changed during plant evolution to give rise to VAMP727, which functions in transporting storage proteins to vacuoles. The first step was the acquisition of a short insertion in its structure through alternative splicing. This insertion contained a non-canonical tyrosine-based motif, which enabled a partial shift in localization from the secretory to the vacuolar transport zone within the trans-Golgi network. Later, the insertion became more acidic and acquired a dileucine-like motif, enhancing its interaction with the AP-4 adaptor complex. These stepwise changes allowed VAMP72 to evolve into VAMP727, supporting the development of the efficient vacuolar transport system found in seed plants.

Seed plants, such as soybeans, store large amounts of protein in specialized organelles called protein storage vacuoles. These proteins not only sustain seedling growth but also serve as a major source of dietary protein for humans and livestock. This protein storage function is unique to plant vacuoles and does not occur in other organisms. During evolution, plants developed a dedicated mechanism to transport large quantities of proteins into vacuoles — but how did this transport pathway, which is absent in animals or fungi, come into existence?

In a recent study published in Current Biology, a research team led by Professor Takashi Ueda of the National Institute for Basic Biology and Associate Professor Masaru Fujimoto of the University of Tokyo has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the stepwise neofunctionalization of a membrane fusion protein called VAMP7.

The team discovered that the plant vacuolar transport system arose through a series of molecular innovations: the appearance of an amino acid insertion within the VAMP7 protein, its acidification over time, and the progressive acquisition and strengthening of binding capacity to the AP-4 adaptor protein complex, which is responsible for cargo selection. These modifications enabled the establishment of a vacuolar transport route unique to seed plants.

Plants contain two major types of VAMP7 proteins: VAMP71, which functions in vacuolar membrane fusion, and VAMP72, which is involved in trafficking to the plasma membrane — part of the secretory pathway.

Professor Ueda, who led the study, explains:
“In addition to these, we previously identified a unique VAMP72-like protein, called VAMP727, in seed plants such as Arabidopsis thaliana. Unlike typical VAMP72s, VAMP727 contains an acidic amino acid-rich insertion of about 20 residues in the N-terminal longin domain. This protein is known to function in vacuolar trafficking and is essential for transporting storage proteins into vacuoles during seed development. However, it was unclear when and how VAMP727 and its associated trafficking pathway emerged during evolution, or what molecular mechanisms underpinned this innovation.”

To address this, the team focused on the molecular evolution of VAMP7. By comparing the amino acid sequences and functions of VAMP72 proteins across a wide range of plant species, from green algae to seed plants, they reconstructed the evolutionary trajectory by which VAMP72, originally functioning in secretion, acquired a vacuolar trafficking role. Based on these insights, they investigated how specific changes in the VAMP72 sequence altered its localization, function, and protein-protein interactions within cells.

Associate Professor Fujimoto, first author of the study, explains:
“Our findings suggest that VAMP72 first gained a partially acidic insertion containing a tyrosine-based motif, enabling a partial functional shift. As this insertion became more acidic and formed an acidic dileucine motif, the protein's interaction with the AP-4 complex was strengthened, resulting in the emergence of VAMP727, a vacuole-targeted VAMP. We believe that this two-step functional transition led to the birth of a new vacuolar transport pathway in plants, allowing for the massive accumulation of storage proteins in seed protein storage vacuoles.”

A phylogenetic tree (left) illustrates the major green plant lineages, from chlorophyte algae to angiosperms. Aligned amino acid sequences (right) show the insertion regions in VAMP72 and VAMP727 homologs from representative species. The emergence of key sequence motifs—such as tyrosine-based and acidic dileucine motifs—occurred in a stepwise fashion during evolution, ultimately giving rise to VAMP727.

Super-resolution confocal live imaging microscopy (SCLIM) reveals the subcellular localization of VAMP727 in wild-type and ap4m mutant Arabidopsis root epidermal cells. In wild-type cells (A and B), VAMP727 predominantly localizes to late endosomes, the trans-Golgi network (TGN), and the interface between these compartments. In ap4m mutants lacking a functional AP-4 complex, VAMP727 exhibits a broadened distribution across the TGN and diminished presence in late endosomes (B). These observations indicate that the AP-4 complex plays a critical role in partitioning VAMP727 within the TGN to facilitate its selective incorporation into the vacuolar transport pathway.

A new metal-free catalytic method for upcycling polyethylene terephthalate (PET) waste into valuable products has been developed. By utilizing ionic liquids (ILs), researchers have achieved an impressive 99% yield of dimethyl terephthalate (DMT) and 91% yield of ethylene carbonate (EC) within 2.5 hours under mild conditions. This innovative process relies on the formation of hydrogen bonds to activate the reactants, enabling the complete conversion of PET. The method offers a sustainable, efficient alternative to traditional recycling techniques, with significant environmental and economic benefits and potential for large-scale industrial implementation.

The global plastic waste crisis, fueled by the ubiquity of polyethylene terephthalate (PET), has driven the search for more effective recycling solutions. Traditional mechanical recycling methods are often inefficient and degrade material quality over time. Chemical recycling via methanolysis has shown promise, but challenges such as incomplete depolymerization and reliance on metal-based catalysts have limited its potential. Ionic liquid-based catalysis has emerged as a promising alternative, providing a metal-free, efficient way to recycle PET. However, achieving complete depolymerization remains a hurdle. Given these challenges, further research into advanced catalytic systems is essential to unlock the full potential of PET upcycling.


In an exciting new study (DOI: 10.1016/j.eehl.2025.100139), researchers from Zhejiang University have introduced a metal-free catalytic approach for upcycling PET waste. Published in Eco-Environment & Health, the research highlights the use of ionic liquids, specifically [EMIm][OAc], to efficiently catalyze the methanolysis of PET. This novel method enables the complete conversion of PET into valuable chemicals, including dimethyl terephthalate (DMT) and ethylene carbonate (EC) within 2.5 hours. The study addresses significant environmental and economic challenges, marking a major step forward in sustainable recycling technologies.

The study presents an innovative metal-free catalytic system designed to upcycle PET waste into high-value products, such as dimethyl terephthalate (DMT) and ethylene carbonate (EC). The key to the method's success lies in the use of ionic liquids (ILs), particularly [EMIm][OAc], which facilitate the complete depolymerization of PET. Under mild conditions, the process achieves an impressive 99% yield of DMT and 91% of EC. The formation of hydrogen bonds between the ionic liquid and the reactants plays a crucial role in activating both the carbonyl groups of PET and the hydroxyl groups of methanol and ethylene glycol.. These interactions enhance the reaction’s efficiency, leading to the full conversion of PET into valuable chemicals.What sets this method apart is its versatility; it can be applied to various polyesters and polycarbonates, extending its potential beyond just PET. Unlike traditional recycling methods that often require metal catalysts, this approach eliminates the risk of metal contamination, offering a cleaner, more sustainable solution. The method’s ability to achieve high yields while reducing energy consumption and avoiding metal residues positions it as a promising solution in the quest for effective plastic recycling on an industrial scale.

Dr. Qingqing Mei, the lead researcher on the study, expressed, "Our research introduces a transformative solution to the plastic waste dilemma, particularly for PET, one of the most challenging plastics to recycle. By employing a metal-free ionic liquid catalyst, we not only improve the efficiency of PET upcycling but also create a sustainable pathway for managing plastic waste. This method holds immense potential for revolutionizing recycling technologies, contributing to a circular economy by turning plastic waste into valuable raw materials that can be reused in manufacturing."

The implications of this research are profound for the recycling industry. This new metal-free method for upcycling PET into high-value chemicals like DMT and EC represents a significant leap forward in sustainable recycling practices. By offering a cleaner, more efficient alternative to traditional methods, it could dramatically reduce the environmental footprint of PET waste, a major contributor to global pollution. Additionally, the method's applicability to various polyesters and polycarbonates broadens its impact, positioning it as a key player in the push for industrial-scale recycling. This development offers a promising route towards a more circular economy, where plastic waste is continuously recycled into valuable materials.
