Canadian-grown wheat, canola and peas have some of the lowest carbon footprints in the world—so low that, in some cases, they could be shipped to Europe 17 times before matching the emissions of the same crops grown there.  The study out of UBC Okanagan, published in Nature Food, compared the carbon footprints of these crops from Canada, France, Germany, Australia and the United States using the ISO 14067 standard.   Led by Dr. Nicole Bamber of UBCO’s Irving K. Barber Faculty of Science, the research ...

BIRMINGHAM, Ala. – Origin-recognition complex, or ORC, plays an unexpectedly broad role in the regulation of human cell gene expression, according to a study in the journal Cell Reports. “This is the first detailed study of how and where ORC regulates epigenetics and gene expression in human cells,” said Anindya Dutta, Ph.D., leader of the study and chair of the University of Alabama at Birmingham Department of Genetics. “The unanticipated scale and breadth of the regulation opens new chapters in ORC biology.” The six-subunit complex was discovered ...

The next time you breathe, consider this: photosynthesis of algae, powered by iron dust in the ocean, made it possible. Now, a new Rutgers University study published in the Proceedings of the National Academy of Sciences pulls back the curtain on this vital process. Iron is a critical micronutrient for marine phytoplankton, the microscopic algae that form the foundation of the ocean’s food webs. It is deposited into the world’s oceans as dust from deserts and arid areas as well as from glacial meltwater. “Every other breath you take includes oxygen from the ocean, ...

Scientists from the Icahn School of Medicine at Mount Sinai, working in collaboration with a team from the University of Texas at El Paso, have developed a novel computational framework for understanding how a region of the brain known as the striatum is involved in the everyday decisions we make and, importantly, how it might factor into impaired decision-making by individuals with psychiatric disorders like post-traumatic stress disorder and substance use disorder. In a study published in Nature Communications [10.1038/s41467-025-61466-x] on August 14, the team reported that modulating activity ...

Omega fatty acids are important to human health, including their role in metabolizing fats. Deviations in their position in a fatty acid chain can signal enzyme malfunctions or pathological metabolic processes, such as those occurring in cancer and autoimmune disorders. Now, researchers from UC San Diego and the University of Graz (Austria) have presented a new computational method to determine omega positions of lipids — the scientific term for fats — in complex biological samples including human tissues and blood. Until ...

Recent advancements in cancer research are shedding light on a novel therapeutic strategy aimed at overcoming the formidable challenge of cancer stem cells (CSCs). These unique cells are known for their remarkable ability to resist conventional therapies, leading to treatment failures and cancer recurrence. A promising new approach involves targeting ferroptosis, a regulated cell death process driven by iron accumulation and lipid peroxidation, which could significantly improve cancer treatment outcomes.   CSCs ...

Rising concentrations of carbon dioxide in the upper atmosphere will change the way geomagnetic storms impact Earth, with potential implications for thousands of orbiting satellites, according to new research led by scientists at the US. National Science Foundation National Center for Atmospheric Research (NSF NCAR). Geomagnetic storms, caused by massive eruptions of charged particles from the surface of the Sun that buffet Earth’s atmosphere, are a growing challenge for our technologically dependent society. The storms temporarily increase the density of the upper atmosphere and therefore the drag on satellites, ...

Researchers in Japan have genetically transferred a unique courtship behavior from one fruit fly species to another. By turning on a single gene in insulin-producing neurons, the team successfully made a species of fruit fly (Drosophila melanogaster) perform a gift-giving ritual it had never done before. The study, published in the journal Science, represents the first example of manipulating a single gene to create new neural connections and transfer behavior between species.   In nature, most male fruit flies court mates by rapidly vibrating their wings to create sound patterns or “courtship songs." However, Drosophila subobscura ...

A network analysis of more than 26,000 dogs and their health conditions helps reveal which diseases tend to go together, providing data that veterinarians and researchers can use to help treat the problems that dog man’s best friend face, according to a study published DATE in the open-access journal PLOS Computational Biology by Antoinette Fang from the Fred Hutchingson Cancer Center in Seattle, Washington, USA, and colleagues. As both humans and their pups age, conditions and diseases accumulate, but some are more likely to be comorbid—or occur together—than ...

While biofuels may be part of the solution to replace fossil fuels and reduce climate-warming carbon emissions, bioenergy needs a new “climate-smart” policy to ensure that it produces both low-carbon products and promotes carbon sequestration, according to Madhu Khanna and colleagues. In this Policy Forum, Khanna et al. note that current policies to promote bioenergy in the United States, such as the Renewable Fuel Standard and Low Carbon Fuel Standard, do not distinguish between carbon intensities ...

Brian Spears and colleagues built a generative machine learning model that was used to successfully predict the outcome of a recent fusion ignition experiment at the U.S. National Ignition Facility (NIF). Their model predicted, with a probability greater than 70%, that ignition was the most likely outcome of the experiment. The findings could guide researchers working on future inertial confinement fusion experiments, which use energetic lasers to compress and heat a capsule of hydrogen isotopes to create nuclear reactions that produce fusion energy. Ignition ...

The first weeks outside the womb are a massive learning experience for the neonatal immune system, especially in the gut as it learns to distinguish helpful from harmful antigens. In mice, maternal antibodies ingested in breast milk in the first week after birth help to regulate immune responses in the newborn gut, according to a new study by Meera Shenoy and colleagues. This process builds the important partnership between the microbiome and host at an early stage, paving the way for nutrient assimilation, avoiding inappropriate inflammation and resistance against pathogens. ...

A careful experiment by Dongsheng Guo and colleagues reveals that maize in a densely planted plot can communicate with neighboring plants through the release of the volatile gas linalool, triggering the roots of its neighbors to release compounds that can change the bacterial composition of the soil. This plant-soil communication helps the plants defend against the increased risk of pests and predation found in high-density plantings, Guo et al. conclude. The findings could aid agricultural researchers looking for ways to sustainably optimize crop yield through different planting patterns and possibly through targeting linalool production. ...

CHAMPAIGN, Ill. — A team of agricultural economists, environmental scientists and policy experts envisions a path toward a carbon-neutral agricultural future by expanding the reach of policies designed to promote low-carbon biofuels for transportation and aviation. In a new paper in the journal Science, the researchers propose policies that would reward farmers for adopting “climate-smart” practices when growing biofuel crops and remove the hurdles that currently thwart such efforts. Climate-smart practices include techniques that build soil carbon, like cover-cropping, not tilling fields after harvest and adding biochar ...

In a new study led by Oxford University’s Department of Chemistry, chemists have demonstrated the synthesis ...

Roughly two-thirds of all emissions of atmospheric methane — a highly potent greenhouse gas that is warming planet Earth — come from microbes that live in oxygen-free environments like wetlands, rice fields, landfills and the guts of cows. Tracking atmospheric methane to its specific sources and quantifying their importance remains a challenge, however. Scientists are pretty good at tracing the sources of the main greenhouse gas, carbon dioxide, to focus on mitigating these emissions. But to trace methane’s origins, scientists often have to measure the isotopic composition of methane's component atoms, carbon and hydrogen, to ...
