The loss of large-bodied grazers worldwide drastically altered fire regimes, increasing grassy ecosystem fire activity. This finding highlights the need to incorporate herbivore controls into fire models to better understand and predict global fire activity.
A study equipped seabirds with tracking technology to track their movements and feeding grounds. The research found that fishing vessels can help identify areas where seabirds go to feed, which is vital for protecting endangered species like the northern fulmar.
Scientists discover a promising approach to creating solid materials for photon upconversion, which can transform wasted long-wavelength light into more useful shorter wavelength light. The new van der Waals crystal solution exhibits outstanding performance and efficiency, enabling the development of novel photonic technologies.
A new study found that 60% of countries involved in SDG partnerships are high- or upper-middle-income, while lower-income countries have limited participation. The unequal distribution of partnerships may hinder sustainable development worldwide.
A new study found that Morpho butterflies adapted to understory habitats have powerful wing-flapping phases for fast flight, while canopy-dwelling species evolved efficient gliding abilities through unique aerodynamic mechanisms. The findings suggest multiple pathways of adaptive evolution for colonizing the forest's canopy.
A new study at the University of Chicago has found that individuals of European and African genetic ancestry respond differently to influenza infection, with a stronger type I interferon pathway activation in those of European ancestry. This variation in immune response may contribute to disparities in influenza outcomes between differ...
Researchers have discovered a specific type of gut bacteria in bees that can improve memory, with bumblebees showing enhanced memory when fed this bacteria. The study suggests a causal link between the gut microbiome and cognitive abilities, opening up possibilities for similar effects in humans.
Research reveals that urban tree leaves bud earlier in US cities compared to rural areas, influenced by warmer temperatures and artificial light, which can accelerate this effect. Artificial light's impact on trees is often overlooked when developing lighting strategies for city streets.
A new study reveals the oldest known punctate ivory pendant found in Eurasia, dating back 41,500 years. The pendant provides direct evidence of Homo sapiens' use of decorative motifs in Poland.
The Life-Saving Lullabies project, funded by UK Arts and Humanities Research Council, investigated the potential of song as a novel public health education intervention to reduce maternal and neonatal mortality. The project's successes demonstrate a model of best practice in community-led maternal and infant health interventions.
The human brain contains trillions of contact points, requiring massive computational resources. Researchers outline the need for exascale computing power to tackle brain complexity.
Researchers have identified a novel mechanism that coordinates the assembly of components inside cells that control gene expression, revealing a widespread role for disordered protein interactions. The findings suggest that disrupting these interactions can lead to impaired gene expression, providing potential new targets for treatment.
CNIO researchers have identified a new biomarker for early melanoma metastasis, proposing the use of NGFR to predict disease prognosis and define risk groups. Blocking NGFR drastically reduces metastasis in mice, paving the way for a potential first treatment to tackle metastasis in its earliest stages.
A systematic literature review found HIV seroprevalence in five key populations: men who have sex with men (MSM), people who inject drugs (PWID), prisoners, sex workers, and transgender people. The review identified significant gaps in data, particularly for transgender individuals.
A study using GDPR-compliant mobile phone data found significant decreases in household mixing during the first two lockdowns, but increases during the third, coinciding with the vaccine rollout.
The study found that 43% of adults aged 50 or older experienced moderate or high levels of depressive symptoms at the beginning of the pandemic, which increased over time. Loneliness was the most significant predictor of worsening depressive symptoms.
Researchers from UC Riverside developed a revolutionary imaging technology that compresses light into a nanometer-sized spot, allowing for unprecedented 6-nanometer color imaging of nanomaterials. This advance improves the study of unique properties and potential applications in electronics and other fields.
A recent study estimates that COVID-19 vaccination prevented almost 470,000 deaths among people aged 60 years and older across Europe. The authors found that early implementation of vaccination was associated with the largest reduction in expected deaths.
Researchers used TRAPPIST-1's harmonious orbits to determine the impact history of its seven Earth-sized planets. The study found that these planets could have withstood only limited late bombardment, implying a relatively small amount of water arrived on time for potential life.
By 2050, renewable electricity is expected to become the cheapest form of energy globally, accounting for up to three-quarters of all demand. This shift can be achieved through accelerated electrification of industries, such as steel production and transportation, which can reduce energy consumption and lower carbon intensity.
A team of scientists has proposed a three-step framework to implement global biodiversity goals at the national level. The first step involves translating global targets into national action plans, engaging various sectors in co-design. The second step requires implementing actions across sectors using behavioral intervention tools and...
A team of researchers solved the case of zirconium-80's missing mass by combining experimental and theoretical approaches. They used NSCL's Penning trap mass spectrometer to measure the nucleus's mass with unprecedented precision, revealing new insights into its structure and properties.
A new study found that genetic ancestry shapes the immune response to the influenza virus, with increased European ancestry associated with a stronger type I IFN response. This finding has potential clinical implications for understanding COVID-19 susceptibility and disease progression.
A new study found that the loss of ancient grassland grazers led to an increase in fire activity globally. Fire extent increased after megagrazer extinctions, with continents that lost more grazers experiencing larger increases.
A new field study in six developing countries finds that community policing did not improve trust between citizens and the police, nor did it reduce crime. The findings suggest that law enforcement agencies need to implement structural changes before incremental reforms can succeed.
A team at the University of Cambridge created a jelly-like material that can withstand compression forces equivalent to an elephant, while maintaining its original shape. The material's properties are seemingly contradictory, but can be controlled through changing the chemical structure of guest molecules.
