On a hot summer day in Colorado, European honeybees (Apis mellifera L.) buzz around a cluster of hives near Boulder Creek. Worker bees taking off in search of water, nectar and pollen mingle with bees that have just returned from the field. Inside the hives, walls of hexagons are beginning to take shape as the bees build their nests. “Building a hive is a beautiful example of honeybees solving a problem collectively,” said Orit Peleg, associate professor in CU Boulder’s Department of Computer Science. “Each bee has a little bit of wax, and each bee knows where to deposit it, ...

A new multiyear study has revealed that between 2018 and 2021, wheat diseases caused the loss of approximately 560 million bushels—valued at US$2.9 billion, or $18.10 per acre, in farmer revenue—across 29 U.S. states and Ontario, Canada. Published in Plant Health Progress™, the study was led by Andrew Friskop (Department of Plant Pathology, North Dakota State University) in collaboration with dozens of university-based specialists and the Crop Protection Network. It represents the most comprehensive survey of wheat-related losses to date. The findings underscore the widespread economic impact of ...

Around 4,000 plant species from different parts of the world secrete nectar outside their flowers, such as on their stems or leaves, through secretory glands known as extrafloral nectaries. Unlike floral nectar, extrafloral nectar does not attract pollinators; rather, it attracts insects that defend plants, such as ants. These insects feed on the sweet liquid and, in return, protect the plant from herbivores. However, this protection comes at a cost. A study published in the Journal of ...

To train artificial intelligence (AI) models, researchers need good data and lots of it. However, most real-world data has already been used, leading scientists to generate synthetic data. While the generated data helps solve the issue of quantity, it may not always have good quality, and assessing its quality has been overlooked. Wei Gao, associate professor of electrical and computer engineering at the University of Pittsburgh Swanson School of Engineering, has collaborated with researchers ...

Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in water—centered on presumed inherent properties rather than external factors, thereby misleading famous philosophers and scientists, from Aristotle to Scottish botanist Robert Brown, in their theorizing.  A new study by a team of psychology researchers has now found that this tendency is in fact common in the history of science. Moreover, through a series of experiments and surveys, the paper’s authors conclude these misfires were likely driven by cognitive constraints, among scientists and non-scientists alike, that have acted ...

LOGAN, UTAH, USA – It’s not easy eating green. Most plants are heavily defended with chemicals to deter plant eaters. For these herbivores, getting enough to eat, while minimizing exposure to toxins, is a persistent challenge that shapes their foraging choices. Understanding how these animals navigate these choices is fundamental to understanding what these creatures need to survive and how species respond to changing conditions, says Utah State University ecologist Sara Weinstein. Woodrats (genus Neotoma) provide an unexpected model for studying animal diets, she says. Native to North America, these herbivorous rodents ...

Every spring, Americans dutifully adjust their clocks forward to daylight saving time, and every fall, back to standard time — but no one seems very happy about it. The biannual time shift is not only inconvenient, it’s also known to be acutely bad for our health. The collective loss of an hour of sleep on the second Sunday in March has been linked to more heart attacks and fatal traffic accidents in the ensuing days. Now, a study by Stanford Medicine researchers finds there are longer-term hazards as well — and better alternatives. The researchers compared how three ...

One fundamental feature of neurodegenerative diseases is a breakdown in communication. Even before brain cells die, the delicate machinery that keeps neurons in touch—by clearing away protein waste at the synapses—starts to fail. When the cleanup falters, the connections between brain cells is impaired and the flow of signals responsible for reasoning, language, memory, and even basic bodily functions is progressively disrupted.  Now, a new study identifies a novel strategy for preventing unwanted proteins from clogging synapses and ultimately congealing into protein plaques. The ...

As a promising technology, multi-energy X-ray imaging technology is expected to be applied for many key fields such as distinguishing the subtle differences in material composition and density, like showing biological skeleton and muscle defects. However, the current multi-energy X-ray imaging technology usually has a high threshold in material selection and device design. To ensure that the imaging resolution reaches the expected level, it is necessary to efficiently couple the multi-layer scintillators with specific energy X-ray response characteristics. ...

The powerful light field manipulation capability of metasurfaces offers a novel development perspective for the quantum precision measurement. By applying the phase-gradient metasurface (PGM) to atomic magnetometers (AMs), we have proposed and experimentally demonstrated a new type of compact single-beam elliptically polarized atomic magnetometers (EPAMs). Employing the fabricated chiral beam splitter PGM with high cross-polarization transmittance, a new atomic spin chirality detection method was devised, enabling the ultra-high sensitivity for extremely weak magnetic ...

These chemical compounds are highly stable and linger in the environment. Thanks to their water-, oil- and stain-repellent properties, they are widely found in everyday items, such as non-stick pans, waterproof clothing, food containers and fire-fighting foams. Their widespread use has harmful effects; they can enter the human body during pregnancy via the placenta and continue to build up through breastfeeding, food, drinking water, polluted air, or contact with products containing them. Due to their impact on health, these chemical ...

Detecting lies involves processing social information. How do people process social information and evaluate honesty? And do people process this information differently when it comes from a friend versus a stranger? Yingjie Liu, from North China University of Science and Technology, led a study to explore how people assess different kinds of information from friends or strangers.  As reported in their JNeurosci paper, the researchers used a neuroimaging technique on 66 healthy volunteers as they communicated on computer screens while sitting across from each other. When the information being communicated led to benefits for pairs, this was considered a “gain” and likewise ...

Background: Osteoporosis is a common skeletal disorder characterized by excessive bone loss, leading to increased fragility and an increased risk of fractures. Osteoclasts, the bone-resorbing cells, are widely recognized as central players in this process. Osteoclast-mediated bone resorption relies critically on two organelles: lysosomes, which degrade the bone matrix, and mitochondria, which provide the necessary energy. Iron, acting as a key connector between lysosomes and mitochondria, has emerged as an essential regulator of osteoclast activity. ...

CHAMPAIGN, Ill. — Cycles of deployment and reintegration can be stressful, disruptive times for military spouses and their families. Although the Department of Defense and its military communities offer a number of formal resources to help military spouses cope during these challenging periods, very few of those who participated in a recent study said they actually used them. Only 16.5% of those in the study had participated in a formal reintegration program after their partners returned from deployment. The findings are concerning and contribute to a growing body of research indicating that thousands of military spouses may not be receiving the support they need ...
