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.
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 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.
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.
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.
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.
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...
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.
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.
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 reduces workers' productivity—even if their workplace is air conditioned, new research shows.
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.
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.
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.
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.
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 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.
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.
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.
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...
This year's Nobel Chemistry winners are pioneers in the nanoworld.
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.
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.
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...
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...
Most Americans take it for granted that the water that comes out of their taps is clean and safe to drink.
Bags made from biodegradable materials for collecting organic household waste have been available on the market for several years. Now researchers in a large-scale pilot study have conducted an extensive investigation into whether these bags fully decompose. In addition, a first-of-its-kind study also took a look into the consumers interest in using biodegradable bags.
To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, University of Copenhagen scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
Whether you’re battling foes in a virtual arena or collaborating with colleagues across the globe, lag-induced disruptions can be a major hindrance to seamless communication and immersive experiences. That’s why researchers have developed new technology to make data transfer over optical fiber communication faster and more efficient.
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, according to new research. The most severe wildfire seasons will become at least twice as frequent.
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. The study’s authors say they have identified giant meanders in the global jet stream that bring polar air southward, locking in frigid or wet conditions concurrently over much of North America...
The rapid spread of oil palm plantations and associated high use of fertilizer raises concerns about the emission of nitrous oxide, a powerful greenhouse gas. A new study shows that oil palms’ photosynthesis and their response to meteorological and soil conditions play an important but still widely unexplored role in the amount of nitrous oxide produced by oil palm plantations.
