Weeds can significantly impact crop yield, leading to a need for effective control methods. A USDA-funded trial demonstrated that cardboard beds reduced weed coverage compared to tilled beds. Farmers found that using cardboard made weeding easier and more efficient after two growing seasons. The results from the trial showed varied crop yields when grown in different bed types.

New research from Texas A&M University indicates that polyethylene microplastics may affect liver health negatively. The study observed significant signs of fatty liver disease linked to polyethylene exposure and a high-fat diet. Researchers found changes in gene activity related to fat metabolism and tissue repair. Future investigations will focus on whether these pollutants contribute to more severe liver damage.

NASA's Perseverance rover has set a new distance record on Mars, traveling 28.10 miles in its mission, eclipsing the previous record of 28.06 miles set by Opportunity in nearly 15 years. This remarkable feat, achieved over five and a half years, showcases Perseverance's advanced autonomous navigation system as it investigates ancient geological structures and collects rock samples to enhance our scientific insights.

Nithya Tammana, a passionate young advocate, noticed rampant water wastage at home, prompting her to launch Save Drop. This initiative has attracted over 450 young changemakers dedicated to preserving water resources. Through impactful campaigns, she stresses the necessity of altering daily water conservation habits. Furthermore, she developed BioLayer, a nature-inspired water filter designed to enhance water quality, earning accolades for her contributions to environmental sustainability.

Nevada’s missing plants and animals are drawing attention as a new journal tracks species that have gone undocumented for decades. The concern comes amid a 38% decline in staffing at the state’s US wildlife agency. Globally, more than 4,300 species have not been documented for over a decade, raising questions about conservation and extinction risks.

Researchers investigating Turkey’s boat-shaped Durupınar formation, believed by some to be Noah’s Ark, have created a 3D-printed model using ground-penetrating radar data. The team has completed its first investigation phase, drilling more than 60 feet underground and collecting samples for laboratory testing. However, many geologists maintain that the formation is a natural geological feature.

Residents of Lismore, a tiny Scottish island with around 190 inhabitants, raised funds for archaeological excavations that uncovered a medieval cemetery, ancient buildings and more than 1,000 metalworking artefacts. The discoveries suggest the island was an important religious and craft centre during the sixth and seventh centuries, shedding new light on early Christianity in northern Britain.

Mosquito attraction differs from person to person, influenced by various elements such as the unique scent of one’s skin and blood type. Studies indicate that specific skin chemicals can make individuals more appealing to mosquitoes. Moreover, the carbon dioxide we exhale is a critical attractant, along with factors like body heat and moisture. Gaining insight into these elements is essential for effective mosquito bite prevention.

Historically, Bright Angel Creek was a sanctuary for various native fish species, including the endangered humpback chub. However, the rise of non-native brown trout has threatened this ecosystem. In an effort to restore balance, the Bright Angel Creek Trout Reduction Project was initiated, successfully eliminating invasive trout and leading to a remarkable 400% increase in native fish populations.
