ITHACA, N.Y. -- Cornell researchers took a novel approach to explore the way microstructure emerges in a 3D-printed metal alloy: They bombarded it with X-rays while the material was being printed. By seeing how the process of thermomechanical deformation creates localized microscale phenomena such as bending, fragmentation and oscillation in real time, the researchers will be able to produce customized materials that incorporate such performance-enhancing characteristics. The group’s paper, “Dendritic Deformation Modes in Additive ...

In the last 20 years, disasters have claimed more than a million lives and caused nearly $3 trillion in economic losses worldwide, according to the United Nations. Disaster relief organizations (DROs) mobilize critical resources to help impacted communities, and they use social media to distribute information rapidly and broadly. Many DROs post content via multiple accounts within a single platform to represent both national and local levels. Specifically examining wildfires in collaboration with the Canadian Red Cross (CRC), new research from the University of Notre Dame contradicts ...

Artificial intelligence (AI) comes with promises of helping coders code faster, drivers drive safer, and making daily tasks less time-consuming. But in a commentary published October 10 in the journal Joule, the founder of Digiconomist demonstrates that the tool, when adopted widely, could have a large energy footprint, which in the future may exceed the power demands of some countries. “Looking at the growing demand for AI service, it’s very likely that energy consumption related to AI will significantly increase in the coming years,” says author Alex de Vries (@DigiEconomist), a Ph.D. candidate at Vrije Universiteit Amsterdam. Since 2022, generative AI, which ...

Adulteration is a bitter truth in the sweet world of honey. As consumers seek nature’s nectar for its purity and health benefits, a shadowy industry taints this golden elixir with hidden additives, most commonly water. Standard detection methods of honey adulteration are expensive, and either have complicated operation methods or low detection accuracy. In Review of Scientific Instruments, from AIP Publishing, a team of scientists from the Nanjing University of Aeronautics and Astronautics ...

Long-term exposure to low-frequency noise can cause numerous health problems, but the solution may be found in an unexpected object, a pingpong ball. Conventionally thought of as the hollow plastic balls that speed through the air during a fast-tempo game of table tennis, with a few modifications, pingpong balls can help absorb the city din. Low-frequency noise is ubiquitous in cities, near roads, and by airports. Though potentially heard as background in the acoustic landscape, it can trigger earaches, respiratory impairment, irritability, and other ...

Recognized as a pivotal developmental transition, flowering marks the continuation of a plant's lifecycle. Flowering time determines the length of plant reproductive period and environmental adaptability. The correct flowering time is very significant for plants to reproduce fruit successfully and is controlled by environment and endogenous signals. Vernalization and photoperiod are the two main flowering pathways orchestrating a large number of floral signals. Methylation is one of the most important epigenetic modifications, which is involved in many key plant growth and development events. Methylation, including histone methylation, DNA methylation ...

Engineers at the University of California San Diego have developed electronic “stickers” that measure the force exerted by one object upon another. The force stickers are wireless, run without batteries and fit in tight spaces. That makes them versatile for a wide range of applications, from arming robots with a sense of touch to elevating the immersive experience of VR and AR, making biomedical devices smarter, monitoring the safety of industrial equipment, and improving the accuracy and efficiency of inventory management in warehouses. They could be used, for example, in knee implants to measure the forces that implants exert on the joint. ...

COLUMBUS, Ohio – In our increasingly polarized society, more people may find themselves in a workplace where they are one of the few conservatives or few liberals around.   A new study found that those whose values – political or otherwise – don’t match the majority in their organization felt they received less respect and as a result were less engaged at work.  Moreover, their co-workers noticed their lack of engagement.   “It is a real issue that organizations face,” said Tracy Dumas, lead author of the study and associate professor of management and human resources at The Ohio State University’s ...

Background    Since Mercury is the closest planet to the Sun among the solar system planets, it is strongly influenced by the solar wind, a high-speed (several hundred km/s) stream of plasma blowing from the Sun. Explorations of Mercury was first carried out by the Mariner 10 spacecraft in 1974 and 1975, which revealed that Mercury has a magnetic field, and thus a magnetosphere, similar to that of Earth. In the 2000s, the MESSENGER spacecraft provided a detailed picture of the Mercury's magnetic field and magnetosphere, and revealed that Mercury's magnetic field center is shifted northward from the planet’s center by approximately ...

University of Virginia researchers are working to outrace two dangerous germs known for quickly developing resistance to new antibiotics – and the scientists’ efforts could help us better combat antibiotic resistance more broadly. A team led by Jason Papin, PhD, is developing sophisticated computer models of Staphylococcus aureus and Pseudomonas aeruginosa, two multi-drug resistant bacteria that infect thousands of Americans every year. The researchers will use their models to better understand the cellular processes and gene activity that make the bacteria ...

INDIANAPOLIS – Knowing which populations are following cancer screening guidelines is important to public health officials and policy makers as well as researchers developing strategies to improve adherence. A recent study is one of the first to compare using health information exchange (HIE) data with patient self-reported data as a means of gathering this intelligence. The researchers found that completeness of information differed by data source and screening test. HIE data provided more information than patient self-reports about ...

Every day we store memories, some of which we are able to recall later. But while we do so, do we keep on storing? Yes! We cannot afford to stop memory formation while we are retrieving prior ones. Imagine, for instance, that you are navigating the city while recalling last night’s events to a friend tagging along. Your brain must memorize aspects of the route even while you are in the story, so that you can find your way back later or reach your next destination. We seem to perform this task without much conscious effort. Big deal, one could say, as we know that the brain has trillions of synaptic connections, so parallel processing ...

A group of ribosomal protein genes connect animal models of depression to human patients with major depressive disorder. In order to research depression treatments, scientists use a mouse model, inducing a state with similarities to depression though exposure to variable, unpredictable, and uncontrolled stressors over days or weeks. But is this state molecularly akin to what humans with major depressive disorder experience? To find out, Xiaolu Zhang, Mahmoud Ali Eladawi, and colleagues examine transcriptomics data from postmortem human brain tissue and from several mouse models of stress, seeking to pinpoint conserved ...

Positron, the antiparticle of electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led to important insights and developments in the fields of elementary particle physics, atomic physics, materials science, astrophysics, and medicine. For instance, positrons are known to be components of antimatter. They are also powerful in detecting lattice defects in solids and semiconductors and in structural analysis of the topmost surface of crystals. Positronic compounds, namely ...

Researchers have known obesity is a risk factor for cardiovascular disease and pregnancy complications related to blood pressure. However, they did not know which factors – obesity or the pregnancy complications – played larger roles in influencing a person’s ...

Increased demand for water due to global population growth, coupled with the increasing frequency of extreme weather events, endangers our water security. Nonetheless, little is known about the relationship of water use by sectors and the occurrence of drought-heatwave events, particularly at the large scale. To unveil this issue, a group of researchers from the Department of Physical Geography from Utrecht University evaluated the responses of sectoral water use during droughts, heatwaves and compound (combined) events at a global scale. The study published in Environmental Research Letters shows that stronger sectoral water use responses are found for heatwaves compared to ...
