Agricultural economists offer food for thought to improve baby formula supply
Black carbon is the most dangerous air pollutant you've never heard of. Its two main sources, diesel exhaust and wood smoke from wildfires and household heating, produce ultrafine air particles that are up to 25 times more of a health hazard per unit compared to other types of particulate matter.
Study finds guided parent-child discussions are effective at addressing subtle racism
The 2022 baby formula crisis highlighted the precarious balance between regulation, competition and safety, according to a recent study published last month.
CRISPR/Cas9-mediated targeted mutagenesis of inulin biosynthesis in rubber dandelion
Experts have long pointed out the need for white parents to have conversations that directly address racism with their children to reduce racial bias. But many parents fail to have these crucial discussions.
Tailoring morphology symmetry of bismuth vanadate photocatalysts for efficient charge separation
Researchers have leveraged the power of the CRISPR/Cas9 genome editing system to enhance natural rubber production in rubber dandelion (Taraxacum kok-saghyz). The CRISPR system's efficiency and precision offer a promising avenue to address challenges faced by the rubber industry.
Irrecoverable carbon in the mountains: Embracing the opportunity of agroforestry
In a study published in the journal Science China Chemistry and led by Prof. Rengui Li (State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences), a distinct charge separation difference has been found via rationally tailoring the morphology symmetry of BiVO4 photocatalyst.
A problem or an opportunity? App-based work separates and isolates workers from their colleagues
Over 29% of global irrecoverable carbon, which once gone is not likely to recover in any reasonable timeframe according to scientific literature, is stored in mountains. This biomass, representing irreplaceable ecosystems, biodiversity, and globally significant ecosystem services, is under threat everywhere by demographic and environmental pressures, as Earth's rapidly changing global climate is...
What does a physicist see when looking at the NFT market?
Feeling hungry, you reach for the phone in your pocket. A few taps later, your meal is delivered to your doorstep. Problem solved: you're no longer hungry. It's so quick and easy it almost feels like magic. But what actually occurs when we place our seemingly simple food order via Wolt, Foodora, or a similar app? How are the individuals working via the apps affected?
Neurobiology: Examining how bats distinguish different sounds
The market for collectible digital assets, or non-fungible tokens, is an interesting example of a physical system with a large scale of complexity, non-trivial dynamics, and an original logic of financial transactions. At the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow, its global statistical features have been analyzed more extensively.
Dogs with epilepsy found to have altered levels of trace elements and heavy metals in their blood and fur
Seba's short-tailed bat (Carollia perspicillata) lives in the subtropical and tropical forests of Central and South America, where it mostly feeds on pepper fruit. The animals spend their days in groups of 10 to 100 individuals in hollow trunks and rocky caverns, and at night they go foraging together. They communicate using sounds that create distinct ambient noise in the colony—like the babble...
Study shows orchid family emerged in northern hemisphere and thrived alongside dinosaurs for 20 million years
A recent study at the University of Helsinki reveals that dogs with epilepsy exhibit distinct alterations in trace elements and heavy metal levels in their blood and fur compared with healthy counterparts.
Cooler, wetter parts of Pacific Northwest likely to see more fires, new simulations predict
In a new study published in New Phytologist, scientists at the Royal Botanic Gardens, Kew, along with partners in Latin America, Asia and Australia, present an updated family tree of orchids, tracing their origins to the northern hemisphere some 85 million years ago. Not only does the study shed new light on their complex and fascinating evolutionary history, but the study's authors hope their...
Entrepreneurs' stock losses bruise their businesses
Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier, according to new modeling led by an Oregon State University scientist.
Three years later, the search for life on Mars continues
When a recession takes a bite out of an entrepreneur's personal stock portfolio, does that person's business suffer more than those of older and larger competitors?
Coast Guard launches 'traffic control for whales' in Washington State's Puget Sound
In the three years since NASA's Perseverance rover touched down on Mars, the NASA science team has made the daily task of investigating the red planet seem almost mundane.
Examining the relationship of reproductive health and economics
Joe Gaydos remembers the beautiful minke whale that washed up on the shore of a San Juan Island in 2022. Illuminated by a pink and orange sunrise, its injuries were consistent with a fatal strike.
Stronger storms free more nutrients from mud flats, finds researcher
Access to reproductive health care—and abortion in particular—is an issue that resonates with voters' deeply held personal beliefs and reflects their underlying moral, philosophical, and religious views. But is it also an economic issue?
Study finds a smoking gun for the spread and evolution of antibiotic resistance
If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas. This is shown by the research of marine biogeochemist Dunia Rios-Yunes at NIOZ in Yerseke. Rios-Yunes will defend her Ph.D. thesis today at the University of Utrecht. "The dynamics of nutrients in deltas and estuaries have been a bit of a blind spot for marine science so...
Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Biomedical engineers at Duke University have uncovered a key link between the spread of antibiotic resistance genes and the evolution of resistance to new drugs in certain pathogens.
Two truths and a lie about immigration
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tissue morphogenesis is limited, largely due to reliance on studies of fixed tissues and cultured cells. Real-time observation of cell shape changes...
Congressional gridlock over border security talks, controversial proposals to restrict asylum and a looming impeachment trial for the U.S. Homeland Security Secretary Alejandro Mayorkas paint a stark picture of a nation deeply divided on immigration.
