Microplastics can reshape heavy metal risks in soil, but each metal responds differently

A new review reveals that microplastics can change the mobility, bioavailability, ecological toxicity, and food-chain transfer of heavy metals, but the direction and magnitude of these changes differ substantially among metals. Biodegradable plastics are not automatically environmentally safer in metal-contaminated soils.

Obesity may accelerate aging through shared biological pathways

Excess body fat promotes chronic inflammation, telomere shortening, mitochondrial dysfunction, and other age-related changes, accelerating the aging process. Weight loss interventions and anti-obesity therapies may partially reverse these changes, improving metabolic function and reducing biological markers linked to aging.

New review advances understanding of Ménière’s disease and points to more targeted treatments

Ménière’s disease is a complex inner ear disorder with diverse symptoms, influenced by genetic susceptibility, immune dysfunction, viral infection, inflammation, and ion regulation. A new review proposes the endolymphatic sac as a central site where multiple factors converge, leading to endolymphatic hydrops and disease progression.

Dana-Farber investigators develop protein degrader discovery platform and find first-in-kind metabolically activated molecular glue degrader

Researchers at Dana-Farber Cancer Institute have developed a protein degrader discovery platform that identifies molecular glues that can target disease-related proteins for elimination. The team discovered the first molecular glue degrader, M12, which is metabolically activated and can degrade multiple cancer-related proteins.

New study shows urban growers rely on accessible educational resources to adopt pollinator-friendly farming practices

A recent study by MSU entomologists found that urban growers' use of pollinator management practices is driven more by access to educational resources and labor than demographics. The researchers surveyed 74 urban growers and found that hard-copy books, online materials, and conversations with fellow growers were the most commonly used...

Study finds severe snow drought more frequent in western US due to climate change

A Montana State University team found that severe snow droughts are four times less frequent in the western US during the preindustrial era compared to today. The study used computer models and historical data to simulate winters under two different climates, revealing a significant difference in drought frequency.

Study finds many Colorado jails still lack public opioid treatment policies despite state mandate

A study by CU Anschutz researchers found that nearly 40% of Colorado's 46 county jails lacked publicly available opioid treatment policies, hindering the implementation of life-saving treatments. The lack of transparency and comprehensive policies poses significant barriers to care for incarcerated people with opioid use disorder.

Ready, set, march: Researchers use math to explain sudden activity bursts in ants

A new study explains how ants synchronize their movements using a mathematical model, revealing that a single active ant can trigger a rapid chain reaction through the colony. The research suggests that individual workers play a crucial role in coordinating collective behavior, operating at high speeds to transmit information efficiently.

Mega-study analyzes the impact of gratitude interventions

Research found that six gratitude interventions had a greater impact than three control measures, with greatest effect from social connection-based practice. Gratitude interventions led to improvements in psychological states linked to human flourishing, including positive affect, feelings of social reciprocity, and life satisfaction.

The brain's searchlight

New study sheds light on the brain's 'searchlight' mechanism, where grid cells subtly probe the environment to guide navigation. Researchers used a low-tech method to measure rats' attention and found that grid cell sweeps follow prey, suggesting a more complex brain function than previously thought.

Low-fat vegan diet cuts dietary energy density by nearly a third, helping explain weight loss, new study finds

A low-fat vegan diet reduces dietary energy density by 30%, enabling participants to eat satisfying amounts of food while taking in fewer calories and losing weight. This approach allows for greater flexibility and sustainability in weight management, focusing on the composition of the diet rather than calorie restriction.

Random physics helps model individual ant motion

A study by OIST researchers has developed a physics-based model to reproduce and predict individual ant movement. The model uses stochastic, or random, modeling to analyze video recordings of ants exploring laboratory environments, allowing for the derivation of predictions about their behavior in new environments.

Siberia’s growing methane threat could offset 20% of global methane reduction targets by 2050

A new study reveals that Siberian permafrost regions are emitting large amounts of methane, with emissions rising by 12.0 Tg between 2010 and 2023. The increase is driven by climate change, with western Siberia experiencing warmer conditions and eastern Siberia becoming drier, leading to an accelerating growth in methane emissions.

Environmental rumbles: A risk to kidney health?

A recent study by researchers at Nagoya University found that low-frequency noise below 100 Hz can cause blood vessel damage to kidneys in mice. The study suggests that the frequency of noise matters more than its loudness, with high-frequency noise having no effect on kidney function.
