Researchers from Umeå University have discovered that ice can dissolve iron minerals more effectively than liquid water—a finding that challenges long-standing assumptions about frozen environments. The study, published in PNAS, shows that ice at –10°C releases more iron from minerals than water at 4°C. This breakthrough may explain why many Arctic rivers are turning rusty orange as thawing permafrost releases iron into waterways. “It may sound counterintuitive, but ice is not a passive frozen block,” says Jean-François Boily, Professor at…

CHAMPAIGN, Ill. — One of ecology’s greatest challenges is to explain what sustains—or undermines—biodiversity within ecosystems. A new study published in Science introduces a model that uses tree census data and genomic information from multiple species to forecast future shifts in species abundance within forests. The research was led by James O’Dwyer, plant biology professor at the University of Illinois Urbana-Champaign, alongside Andy Jones of Oregon State University and James Lutz of Utah State University. Why Predicting Species Abundance Matters…

As wildfires continue to intensify and spread across the Western United States, researchers from Colorado, Utah, and California are examining how wildfire smoke alters air quality and impacts human health. A new study published in Atmospheric Environment reveals that massive wildfires in states such as Colorado, Oregon, and California generate significant amounts of ozone in the atmosphere. This worsens respiratory health risks and further contributes to climate warming. Research Collaboration Across Universities The project was a joint effort led by…

New research reveals “unprecedented” conservation results of community-based management of protected areas in the Amazon – as many face a future in which they may become increasingly degraded due to low enforcement of regulations, growing external encroachment and competition for resources. The study describes a powerful new mechanism for increasing the extent of effective area-based protection by piggybacking on community management of natural resources. Tropical protected areas are typically understaffed, underfunded and underequipped and it remains unclear how existing ones…

New research from Curtin University has uncovered a remarkable connection between the large-scale structure of our galaxy and the long-term evolution of Earth’s crust. The study suggests that our planet’s development was shaped not only by internal geological processes but also by meteorite impacts triggered during the Solar System’s journey through the Milky Way. Published in Physical Review Research, the findings indicate that the chemical composition of ancient zircon crystals embedded in Earth’s crust reflects periodic meteorite bombardments that occurred…

The lentils now grown in the Canary Islands have a history that stretches back almost 2,000 years on the site. This is shown in the very first genetic study of archaeological lentils, carried out by researchers at Linköping University and the University of Las Palmas de Gran Canaria in Spain. Since these lentils have been adapted for cultivation in hot and dry climates for a very long time, they may become valuable for plant breeding in the light of ongoing…

A recent study indicates that early Mars’ atmosphere may have been conducive to life, potentially due to volcanic activity that released sulphur gases, so facilitating a greenhouse warming effect. This discovery originates from a study published in Science Advances, conducted by researchers at The University of Texas at Austin. Utilising data from Martian meteorite compositions, the researchers conducted over 40 computer simulations with varying temperatures, concentrations, and chemical compositions to predict the potential emissions of carbon, nitrogen, and sulphide gases…

Tokyo, Japan – Researchers from Tokyo Metropolitan University have traced the genetic origins of a now extinct plant population from Nishinoshima, a remote volcanic island known for its frequent eruptions that periodically wipe out vegetation. Their analysis revealed that while the plants likely originated from a nearby island, their genetic makeup displayed unique traits shaped by a phenomenon known as the “founder’s effect.” The findings provide rare insight into the earliest stages of ecosystem formation in isolated environments. Volcanic Resets…

STUTTGART/MELBOURNE, 8 September 2025 — A joint research team from the University of Stuttgart (Germany) and the University of Melbourne (Australia) has developed a simple, affordable method for detecting nanoplastics in environmental samples. Using only a standard optical microscope and a specially designed test strip—the “optical sieve”—scientists can now visualize and analyze particles that were previously invisible without expensive, high-tech equipment. The breakthrough has been published in Nature Photonics (doi: 10.1038/s41566-025-01733-x). “The test strip can serve as a simple analysis…

A new 30-year study has confirmed that East Antarctica’s interior is warming more rapidly than its coastal regions—and much earlier than previously thought. Published in Nature Communications and led by Professor Naoyuki Kurita of Nagoya University, the research identifies a major driver of this change: intensified warm air flow linked to temperature variations in the Southern Indian Ocean. Because East Antarctica contains the majority of the planet’s glacial ice, this discovery suggests that current models may underestimate how quickly Antarctic…

A new species of marsupial, closely related to the kangaroo, has been identified through fossil evidence from caves in the Nullarbor and southwest Australia. Researchers from Curtin University, the Western Australian Museum, and Murdoch University revealed the discovery of a previously unknown bettong species, along with two new subspecies of the woylie. Tragically, the newly identified species is already believed to be extinct. The Role of Woylies in the Ecosystem Woylies, also known as brush-tailed bettongs, are small marsupials native…

Palaeontologists at the University of Leicester have solved a 150-million-year-old puzzle: how two baby pterosaurs met their end. According to a new study published in Current Biology, the young reptiles perished in violent storms, which also created the perfect conditions for their exceptional preservation in stone. Fragile Creatures in a Fossil World of Giants The Mesozoic Era, often remembered as the “Age of Reptiles,” is typically associated with giant dinosaurs, marine predators, and vast-winged pterosaurs. However, as in today’s ecosystems,…

WASHINGTON, Sept. 3, 2025 — Detecting microplastics in the environment could soon become faster and more affordable thanks to a new biosensor developed by scientists and published today in ACS Sensors. The living sensor, built from a safe laboratory strain of Pseudomonas aeruginosa, attaches to plastic and glows green under fluorescence, making even tiny plastic fragments visible in water samples. Tackling the Microplastics Problem Microplastics—tiny fragments of plastic often invisible to the naked eye—are now found in air, soil, and…

New seismic evidence reveals the Red Planet’s mantle preserves chaotic remnants of its violent beginnings The inside of Mars isn’t the neatly layered structure often shown in textbooks. Instead, scientists have discovered a “chunky” interior — more like a Rocky Road brownie than the tidy layers of a Millionaire’s Shortbread. Published in Science, the study shows that Mars’s mantle contains preserved fragments up to 4 km wide, dating back to the planet’s formation. These pieces act like geological fossils, offering…

Ecologists have documented a remarkable behavior in the nocturnal sheet web spider Psechrus clavis: using the bioluminescent glow of trapped fireflies as bait to attract additional prey. The study, published in the British Ecological Society’s Journal of Animal Ecology, provides one of the rare examples of a predator exploiting its prey’s mating signals for its own advantage. Fireflies as Living Lures Researchers at Tunghai University in Taiwan observed P. clavis capturing fireflies in its web but not consuming them immediately….

A fossilized sea creature that lived more than 500 million years ago is offering fresh insights into the evolutionary history of arthropods—the most diverse and successful group of animals on Earth. The study, published in Nature Communications, addresses one of the last major enigmas of arthropod evolution: the division between mandibulates (insects, crustaceans, centipedes, and millipedes) and chelicerates (spiders, scorpions, and related species). Researchers have determined that Jianfengia multisegmentalis, a segmented marine creature, represents an early ancestor of mandibulates, overturning…
