Scottish researchers are discovering new ways of combating environmental damage caused by acid mine drainage in Scotland by studying bacteria that can degrade dangerous waste products.

Honey bees—plump, fuzzy, and famed for their honey-making—capture the popular imagination. Yet, wild bees are equally vital for pollination and, by some measures, outshine honey bees as pollinators. This is why UBC researcher Matthew Mitchell and his colleagues are deeply concerned about their declining populations.

Scientists have determined the structure of a new material with the potential to be used in solar energy, batteries, and splitting water to produce hydrogen.

Most Americans report having personally experienced the effects of extreme weather, according to new survey data from the Annenberg Public Policy Center that finds support for pro-environmental government policies meant to lessen the effects of climate change.

Small loans can help people establish and expand their small businesses. A field study in Ghana has now revealed that men ask for and receive more money from microcredit companies than women. However, if women are better informed, they are more likely to apply for higher amounts.

Research has investigated compulsive online shopping behavior in India, with a specific focus aimed at unzipping the triggers and antecedents related to the purchase of jeans. The research is published in the International Journal of Networking and Virtual Organisations.

Nitrogen is a nutrient essential for all life on Earth. Although nitrogen gas (N2) is plentiful, it is largely unavailable to most organisms without a process known as nitrogen fixation, which converts dinitrogen to ammonium—a major inorganic nitrogen source.

Online shopping and digital payment options have made shopping easier and more enjoyable—money can be spent almost unnoticeably. These factors predispose people to impulse purchases. A lack of budgeting and cost control may lead a consumer into financial problems.

Until now, groundwater—a critical water resource around the globe, especially in dry regions—has been largely unstudied in its importance and role in sustaining ecosystems. A new research effort led by the SUNY College of Environmental Science and Forestry (ESF) in partnership with University of California Santa Barbara (UCSB), Cardiff University, and Desert Research Institute (DRI) examines the relationship between groundwater and ecosystems across California.

In the quaint town of Gamboa, nestled near the Panama Canal, a team of scientists embarked on a unique endeavor: attaching red flags onto the legs of crickets and observing how birds respond to them. These eye-catching flags were borrowed from the matador bug (Anisoscelis alipes), an insect renowned for the colorful adornments on its hind legs. This trait has captivated Smithsonian postdoctoral fellow Ummat Somjee for several years, particularly given the matador bug's tendency to wave them. The persisting question... Читать дальше...

Carnation (Dianthus caryophyllus L.) is a flower widely cultivated for its appealing appearance and fragrance. However, it faces postharvest challenges that can affect its ornamental quality, primarily due to water stress and microbial growth.

Passion fruit (Passiflora edulis), renowned for its nutritional richness and aromatic fruits, is widely cultivated in tropical and subtropical regions. Passion fruit can not only be harvested year-round but also can be used as a horticultural plant, which contributes significantly to its economic value.

Zinnia elegans is an annual herbaceous ornamental flower widely cultivated in domestic and foreign gardens due to its diversity in flower types, color, and landscaping versatility. The Petal color of Zinnia elegans ranges widely from red to orange and yellow due to the different content of carotenoids and anthocyanins.

What data needs to be collected for the evidence-based design of strategies to ensure that cocoa farming households substantially progress towards or achieve a living income? Evidence-based strategies have to be designed to ensure cocoa farming households obtain a living income. How can data contribute to designing such strategies?

High entropy alloys (HEAs) have attracted significant attention in various fields due to their unique properties such as high strength and hardness, and high thermal and chemical stabilities.

A research team led by the University of Massachusetts Amherst, in collaboration with the University of Alaska-Anchorage and Columbia University, has conducted the widest-ever hydrological tracer analysis of the Dry Andes region in Chile, Argentina and Bolivia, home to the majority of the world's lithium deposits and other elements, such as copper, critical to the green energy transition away from oil and toward electricity.

New research from the Rice University Kinder Institute for Urban Research's Houston Education Research Consortium (HERC) finds that female students may be more likely to stick with STEM curriculum when they receive support from high school guidance counselors.

The upper-stage helium tank of the Ariane 3 that was launched in 1985 was recovered in Uganda in 2002 after re-entry. Molten aluminum splashes were discovered on the tank, which have been identified as deposits from local fixings.

Results of a new survey suggest a positive organizational culture is the top non-financial factor impacting well-being at work for most individuals, but younger Gen Z workers place more value on flexibility.

Awe, amazement and wonder are a few of the reactions humans have to a solar eclipse. The extremely rare occasion of being in the path of totality—where the moon's disk completely blocks the sun for a few short moments—captivates audiences and inspires a sense of excitement.

A new study finds that universities scoring strongly on measures of sustainability are associated with innovation and economic growth in their surrounding communities. However, the study did not find similar connections between university sustainability performance and environmental sustainability in their home communities.

Apple puree is a major market player, integral to various products, yet its quality varies with the diversity of apple cultivars and processing conditions. For fruit processors, the ever-increasing variability of raw fruits means that their empirical know-how may not be sufficient to produce expected and constant final purees.

A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.

Decentralized finance systems (DeFi) is a new blockchain-based solution, where transactions are carried out automatically through smart contracts without any intermediaries (banks, brokers, etc.), while users have direct control over their assets.

A new study has shown pollen grains can be used as green templates for producing biomaterials, showcasing their potential to support drug delivery and bone regeneration.
