Speaking up and feeling empowered? How promotion-oriented voice can navigate dynamics between power and action
In the corridors of British power, former prime minister Margaret Thatcher was quoted as saying: "Don't give me problems, give me solutions." The so-called Iron Lady, who died in 2013, had no truck with fault-finding negativity: she wanted actionable.....»»
Hidden DNA in plants reveals secrets of photosynthesis
Scientists have uncovered genetic variation in the unexplored DNA of the photosynthetic and energy factories of Arabidopsis plants, which plays a crucial role in the efficiency of photosynthesis in plants. These insights—published Nov. 27 in the Pr.....»»
Ancient maize samples in Brazilian caves suggest the crop"s domestication may have been completed in South America
Brazilian scientists have determined that ancient specimens of partially domesticated maize (Zea mays, also known as corn) originally from Peruaçu Valley in Minas Gerais state (Brazil) were the farthest from Mexico, the plant's historic center of or.....»»
Research offers insights into Permian Basin earthquake hazards

"Forever chemicals" are polluting African waters
Every week seems to bring a new report about where "forever chemicals" have been found: in soil, drinking water, our bodies and marine animals. Their proper scientific name is perfluoroalkyl and polyfluoroalkyl substances (PFAS). But they're more com.....»»
Enterococcus helps E. coli "armor up" in dog and poultry co-infections
A new study finds that two subtypes of pathogenic Escherichia coli (E. coli) produce five to 16 times more protective capsular "slime" when Enterococcus faecalis (EF) is present. The finding could lead to targeted therapies for E. coli infections spe.....»»
Cool water from the deep could protect pockets of the Great Barrier Reef into the 2080s
For coral reefs, climate change is an existential threat. Australia's Great Barrier Reef has endured seven mass bleaching events over the past 25 years. Five have occurred in the past eight years......»»

Gators may be a key gauge of how climate change may impact Florida"s Everglades
A bright searchlight pierces the darkness as the 18-foot airboat glides across the Everglades, the beam igniting small sparkling shimmers in the ink-black water dotted with lily pads......»»
How a species of ground squirrel manages to go without food and water over the winter months
A team of molecular and physiology specialists at the Yale University School of Medicine has uncovered some of the hibernating secrets of thirteen-lined ground squirrels, and have partly explained how it manages to avoid thirst during its long winter.....»»
Deep clear-water lake analysis shows shallow water areas crucial for nutrient balance in lakes
Even deep clear water lakes, which are considered particularly valuable ecosystems, can show signs of eutrophication and algae growth—often for no apparent reason......»»
Water treatment: Catching steroid hormones with nanotubes
Steroid hormones are among the most widespread aquatic micropollutants. They are harmful to human health, and they cause ecological imbalances in aquatic environments......»»
How sharing stories about river restoration can inspire others to take care of waterways
Water is the lifeblood of our planet. But in Aotearoa, New Zealand, a staggering two-thirds of the rivers monitored for water quality are classified as unswimmable. Only 2% of large lakes are deemed to be in "good health.".....»»
Smart analysis enhances detection of fecal discharges from Danube shipping
Researchers at Karl Landsteiner University of Health Sciences (KL Krems) and ICC Water & Health have developed a new, integrative methodology that enables precise detection of small-scale fecal discharges from inland waterway vessels in flowing water.....»»
Researchers use eDNA metabarcoding to identify pollinators, aiming to boost crop production
A Curtin University study has revealed that a new method of capturing DNA could provide farmers with a valuable tool for boosting crop production—while also benefiting the environment......»»
How queen bees and wasps set backyards abuzz in readiness for summer
As we transition to warmer weather in the austral summer, many changes take place. Domestic dogs and cats may shed winter coats. Fish such as bass and trout prepare fat reserves for migrations to deeper waters. And social insect queens emerge from hi.....»»
Satellite evidence points to climate-induced poisoning of over 300 African elephants
A study led by King's College London has provided further evidence that the deaths of 350 African elephants in Botswana during 2020 were the result of drinking from water holes where toxic algae populations had exploded due to climate change......»»
