Scientists warn invasive Asian mantises are threatening Europe's wildlife
Scientists warn invasive Asian mantises are threatening Europe's wildlife
Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast-breeding predators are expand
Cast away: Tracing the voyage of a plastic bottle cap and its hitchhiking marine species
Researchers have traced the journey of a plastic bottle cap recovered near the waters of southern Japan by combining data from the label, chemical clues in tiny shells and ocean current simulations. They found 307 organisms, including a polychaete worm not found in Japanese water
Wildlife conservation work to get £1m boost
Endangered rodents, birds and butterflies will be among the species benefitting from the investment. O recorte ajuda a contextualizar a pauta dentro de Agro.
When species are forced to move: Prediction models underestimate climate-related extinctio
When species are forced to move: Prediction models underestimate climate-related extinctio
Climate change threatens many plant and animal species not only when their habitats disappear as climatic conditions change, but also when those habitats shift. In a new study, a team of University of Potsdam researchers found that whether a species' habitat disappears or shifts
Scientists finally solved the mystery of Earth's greatest mass extinction
Scientists finally solved the mystery of Earth's greatest mass extinction
Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms
Columbia scientists discover surprising link between serotonin and heart valve disease
Columbia scientists discover surprising link between serotonin and heart valve disease
Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests that patients with degenerative mitral regurgitation who take SSRI antidepressants
Scientists discover how the brain rewires itself to truly multitask
Scientists discover how the brain rewires itself to truly multitask
Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better
First came the dead fish, then invasive plants. A year later and Lake Suchitlán’s pollutio
First came the dead fish, then invasive plants. A year later and Lake Suchitlán’s pollutio
Fishers on El Salvador’s largest lake are still looking for answers after the die-off, with no explanation provided by the governmentFrom the village of Copapayo, Noel Avalos recalls the morning they ran to the shore of Lake Suchitlán, El Salvador’s main hydroelectric reservoir,
Invasive aoudad pose deadly risk to native bighorn sheep
Invasive aoudad pose deadly risk to native bighorn sheep
An invasive species found across West Texas may pose a greater threat to native bighorn sheep than previously understood.
Twisted ultrathin magnet retains magnetization after field changes, study finds
Twisted ultrathin magnet retains magnetization after field changes, study finds
The properties of ultrathin magnets can be specifically altered by a slight twist between two atomic monolayers. This is the conclusion reached by an international research team led by TU Darmstadt in a study published in Nature Communications. The findings open new prospects for
For time-critical events: NINJA prepares for first on-sky observations
For time-critical events: NINJA prepares for first on-sky observations
This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic events, such as the electromagnetic counterparts of gr
Hidden muscle machinery reveals 50 new gene subfamilies across vertebrates
Hidden muscle machinery reveals 50 new gene subfamilies across vertebrates
Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a muscle contraction. This function, discovered in mammals a century ago, has been presumed by scientists to operate the same way among birds, reptiles, amph
