Q&A: Colorado's Latina legislators giving voice to their communities
Betty Benavidez strove to improve access to better education in her west Denver neighborhood. She worked in her local schools and founded action centers, belonged to the Hispanic Education Leadership Program and the West High School PTA, and was district captain for the Democratic party to mobilize Mexican-American voters.
Exploring stellar hydrogen burning via muons and nuclei
The muon is a subatomic particle that resembles an electron but is 200 times heavier. It interacts with nuclei through the weak force, one of the four fundamental forces in the universe. When a muon binds with a deuteron (composed of one proton and one neutron), it forms a system with two neutrons. This process is analogous to proton-proton fusion, where two protons combine to form a deuteron.
Simultaneous large wildfires will increase in Western US, says study
Simultaneous outbreaks of large wildfires will become more frequent in the Western United States this century as the climate warms, putting major strains on efforts to fight fires, new research shows.
Recent research expedition reveals alarming extent of coral mortality in Florida
Scientists from Chicago's Shedd Aquarium, a leader in conservation research, returned from a multi-institutional research expedition to survey coral bleaching impacts from Miami and the Florida Keys to the Dry Tortugas, following an unprecedented rise in ocean temperatures.
Invertebrate biodiversity is improving in England's rivers, long-term trends show
Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a study led by UK Centre for Ecology & Hydrology (UKCEH) researchers.
2023 GAP Report: Only by working together will agricultural productivity meet demand
Agricultural productivity growth is crucial for ensuring food security and for meeting the nutritional needs of a growing global population while simultaneously meeting environmental goals.
Extracellular vesicles study outlines new strategies to combat neurodegenerative diseases
A new study by the University of Barcelona could drive the design of future strategies to regenerate damaged brain areas in neurodegenerative diseases. The study emphasizes the role of neuron-derived extracellular vesicles in the processes that modulate synaptic plasticity and neuronal signaling pathways. In addition, the results outline a new scenario for using these extracellular vesicles...
New research finds that ancient carbon in rocks releases as much carbon dioxide as the world's volcanoes
A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the journal Nature, have important implications for modeling climate change scenarios.
Study identifies jet-stream pattern that locks in extreme winter cold, wet spells
Winter is coming—eventually. And while the Earth is warming, a new study suggests that the atmosphere is being pushed around in ways that cause long bouts of extreme winter cold or wet in some regions.
Pandemic found to have boosted gardening, hunting in New York State
A survey of New York state residents found that nearly half of respondents increased the amount of time they spent on wild and backyard food in the early months of the COVID-19 pandemic—confirming anecdotes about increases in activities such as sourdough baking, fishing and gardening.
Hot weather hits productivity—even in air-conditioned factories
Hot weather reduces workers' productivity—even if their workplace is air conditioned, new research shows.
AI analyzes bird sightings to help conserve species
For the first time, big data and artificial intelligence are being used to model hidden patterns in nature—not just for one bird species, but for entire ecological communities across continents.
Professor helps accounting research catch up with a fast-changing economy
It's a time of transformation for capital markets. And Maria Nykyforovych, assistant professor of accounting at George Mason University School of Business, believes that accounting research can help resolve the confusions of economic change. But scholars must update their thinking first.
Underappreciation of LGBT executives creates investment opportunity, says study
Academics from Northumbria University have uncovered an "extreme underappreciation" of firms with CEOs who are openly gay, lesbian, trans or bisexual—and they say it's driven by discrimination.
Machine learning reveals how to dissolve polymeric materials in organic solvents
Dissolving polymers with organic solvents is the essential process in the research and development of polymeric materials, including polymer synthesis, refining, painting, and coating. Now more than ever recycling plastic waste is a particularly imperative part of reducing carbon produced by the materials development processes.
Pandemic posed vocabulary challenges for preschoolers, study reveals
When it came to learning language, money mattered for pandemic preschoolers, according to a new study out of U of T Mississauga's Child Language and Speech Studies (CLASS) Lab.
Seabird couples with similar personalities make better parents, finds study
Seabird couples with similar personalities are more likely to be successful parents, which in turn makes them less likely to seek another partner, according to a new study by the University of Liverpool.
How proteins roll the dice to determine bee sex
To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) including biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In the current issue of the journal Science Advances, they describe how this process is similar to a game involving two dice.
New study shows signs of early creation of modern human identities
Early ancestors collected eye-catching shells that radically changed the way we looked at ourselves and others. A new study confirms previous scant evidence and supports a multistep evolutionary scenario for the culturalization of the human body.
Ruffed grouse population more resilient than expected, genetic study finds
Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented. The study, led by Penn State and Pennsylvania Game Commission researchers, is published in Molecular...
Three giants of chemistry connected by the quantum realm
This year's Nobel Chemistry winners are pioneers in the nanoworld.
Brazil vows more aid as Amazon waters dry up
Brazil's Vice-President Geraldo Alckmin said Wednesday that more help would be sent to an Amazon state where rivers are drying up in a severe drought, causing mass die-offs of fish and dolphins.
Oops! Nobel chemistry winners are announced early in rare slip-up
The most prestigious and secretive prize in science ran headfirst into the digital era Wednesday when Swedish media got an emailed press release revealing the winners of the Nobel Prize in chemistry and the news prematurely went public.
Demystifying the role of plant x- and y-type thioredoxins
The potential for exposure to fluctuating light has necessitated that plants evolve protective mechanisms for when the light intensity exceeds photosynthetic capacity. Under these conditions, reactive oxygen species cause photoinhibition, which hinders photosynthetic efficiency. To counter this loss in photosynthetic efficiency, chloroplasts evolved thioredoxin (Trx) proteins that regulate redox...
Navigating moiré physics and photonics with band offset tuning
When two lattices with distinct angles or periodicities come together, they conjure a moiré superlattice—a realm where astonishing phenomena like superconductivity and optical solitons spring to life. At the heart of this realm lies the moiré flatband, a key player in shaping advanced light–matter interactions, such as laser emission and second harmonic generation. In moiré physics and its...
