Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.

Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.

Farmland often harbors a multitude of pathogens which attack plants and reduce yields. A research team has now shown that inoculating the soil with mycorrhizal fungi can help maintain or even improve yields without the use of additional fertilizers or pesticides. In a large-scale field trial, plant yield increased by up to 40 percent.

Plastic waste in the water might be stopping -- or interrupting -- some shrimp-like creatures from reproducing. In a unique study, the ability of 'shrimp like' creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.

Found in fishing nets, carpet, clothing, Nylon-6 is a major contributor to plastic pollution, including ocean pollution. Now, chemists have developed a new catalyst that quickly, cleanly and completely breaks down Nylon-6 in a matter of minutes -- without generating harmful byproducts. Even better: The process does not require toxic solvents, expensive materials or extreme conditions, making it practical for everyday applications. In experiments, the new process recovered 99% of the polymer's building blocks, which can then be upcycled into higher-value products.

Melting of glaciers, rising sea levels, extreme heat waves: the consequences of climate change are more visible than ever, and the scientific community has confirmed that humans are responsible. Yet studies show that a third of the population still doubts or disputes these facts. The cause is disinformation spread by certain vested interests. To try and prevent this phenomenon, a team has developed and tested six psychological interventions on nearly 7,000 participants from twelve countries. The research highlights the extremely persuasive nature of disinformation and the need to strengthen our efforts to combat it.

With the world projected to be highly urbanized by 2050, cities are encouraged to take urgent climate actions to mitigate and adapt to the threats of climate change. As climate change intensifies and urbanization increases rapidly, local governments are expected now more than ever to lead climate action planning. However, studies show the limitations of the existing climate action plans (CAPs). So scientists have created an Urban Climate Action Planning (UCAP) framework to guide the development of suitable urban CAPs and support the assessment of the level of suitability of these plans.

A new study examined placentas donated by women who delivered in Hawaii from 2006 to 2021, and found the presence of microplastic particles in the placenta.

The San Joaquin Valley in California has experienced vast variability in climate extremes, with droughts and floods that were more severe and lasted longer than what has been seen in the modern record, according to a new study of 600 years of tree rings from the valley.

World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.

Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on approaches that dissolve the battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process. This simple, efficient and environmentally-friendly solution overcomes the main obstacles presented by previous approaches.

A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.

Planting flowers beside food crops on farms in India attracts bees, boosts pollination and improves crop yield and quality, researchers have found.

A new study found that unfiltered air from rush-hour traffic significantly increased passengers' blood pressure, both while in the car and up to 24 hours later.

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.

Scientists are warning that apparently stable glaciers in the Antarctic can 'switch very rapidly' and lose large quantities of ice as a result of warmer oceans.    Their finding comes after glaciologists used satellites to track the Cadman Glacier, which drains into Beascochea Bay, on the west Antarctic peninsula.

A promising new form of ammonium phosphate fertilizer has been field-tested. The fertilizer, struvite, offers a triple win for sustainability and crop production, as it recycles nutrients from wastewater streams, reduces leaching of phosphorus and nitrogen in agricultural soils, and maintains or improves soybean yield compared to conventional phosphorus fertilizers.
