Graphene, composed of layers of carbon atoms arranged in a honeycomb pattern, is recognized as a supermaterial due to its exceptional conductivity and mechanical advantages. These properties are key to advancing flexible electronics, innovative batteries, and composite materials for aerospace applications. Despite these benefits, creating elastic and durable films has been difficult. In a recent edition of Angewandte Chemie, researchers have proposed a solution by connecting graphene nanolayers through extendable bridging structures, potentially overcoming previous limitations.

The special capabilities of microscopic graphene nanolayers often drop off when the layers are assembled into foils, because they are only held together by relatively weak interactions—primarily hydrogen bonds. Approaches that attempt to improve the mechanical properties of graphene foils by introducing stronger interactions have only been partially successful, leaving particular room for improvement in the stretchability and toughness of the materials.

This research highlights that both early melting-volatilization and late accretion of volatile-rich materials are integral to understanding the distribution of nitrogen in silicate Earth. These insights open new avenues for understanding the origins of volatiles on Earth.

A team of researchers led by Professor Wang Wenzhong from the University of Science and Technology of China’s School of Earth and Space Sciences, in partnership with international experts, examined how nitrogen isotopes fractionate during the formation and evolution of terrestrial planets. Their findings were published in Nature Communications.

Currently, the academic community primarily holds two models regarding the accretion of volatiles on Earth: the “Late Veneer” model and the “Early Evolution” model.

Scientists have utilized a quantum annealer to simulate quantum materials effectively, marking a crucial development in applying quantum computing in material science and enhancing quantum memory device performance.

Physicists have long been pursuing the idea of simulating quantum particles with a computer that is itself made up of quantum particles. This is exactly what scientists at Forschungszentrum Jülich have done together with colleagues from Slovenia. They used a quantum annealer to model a real-life quantum material and showed that the quantum annealer can directly mirror the microscopic interactions of electrons in the material. The result is a significant advancement in the field, showcasing the practical applicability of quantum computing in solving complex material science problems. Furthermore, the researchers discovered factors that can improve the durability and energy efficiency of quantum memory devices.

MIT physicists have developed a new form of graphene, creating a five-lane electron superhighway that allows for ultra-efficient electron movement without energy loss.

This breakthrough in rhombohedral pentalayer graphene could transform low-power electronic devices and operates via the quantum anomalous Hall effect at zero magnetic field.

MIT physicists and their collaborators have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more.

A UCLA Health study explored the traits of resilient individuals, discovering significant neural activities in the brain regions for cognition and emotional regulation, and healthy gut microbiome activities.

The research highlighted differences in microbiome metabolites and gene activity, indicating lower inflammation and better gut health in resilient people compared to less resilient individuals. This comprehensive approach may lead to interventions that enhance resilience to stress, possibly preventing various health issues.

Resilience and Health.

Recent research on isoporous membranes, which feature uniformly sized pores, show potential for improving the precision and efficiency of industrial separation processes by allowing solutes multiple attempts to pass through the pores.

Imagine a close basketball game that comes down to the final shot. The probability of the ball going through the hoop might be fairly low, but it would dramatically increase if the player were afforded the opportunity to shoot it over and over.

A similar idea is at play in the scientific field of membrane separations, a key process central to industries that include everything from biotechnology to petrochemicals to water treatment to food and beverage.

Second, ants need to climb or hold onto the vehicle after locating it. The metallic paint on the vehicle surface is slippery and may potentially select for species with good climbing/gripping abilities. The climbing and moving performance of ants is determined by the morphological characteristics of leg segments (Beutel et al., 2020). Arboreal ants have hooked pretarsal claws, well-developed adhesive pads and fine tarsal hairs, allowing them to walk on smooth vertical substrates. Ground-dwelling ants, on the contrary, are less capable of moving on smooth surfaces such as vehicle paint because of their straight pretarsal claws and the lack of adhesive pads and tarsal hairs (Orivel et al., 2001).

Third, the temperature on the surface and in the interior of the vehicle can increase dramatically when exposed to sunlight, especially in the summer, indicating the thermal tolerance of hitchhiking species may play an important role in determining their colonisation success (Nixon et al., 2019). Arboreal ants are generally more heat-and drought-tolerant than ground-dwelling ants are (Hood & Tschinkel, 1990 ; Leahy et al., 2022), which could potentially translate into a higher probability of successful establishment at the destination due to better survival chance with high temperatures on or in the vehicle.

It is likely that ant hitchhiking events would be much more common than what has been reported through our Facebook group. We suspect that whether vehicle owners are aware of the Facebook group and/or vehicle owners are willing to report their observations to our Facebook group would play a critical role in the number of incidents we received for this citizen science project. Nonetheless, we were able to record at least 52 hitchhiking cases with complete information over a 7-year period. Despite a relatively small dataset, the estimated sampling completeness was appropriate (Figure S3). To our knowledge, this is the first report profiling active ant hitchhiking on vehicles via citizen science efforts, highlighting the importance of establishing a predictive framework for forecasting future hitchhikers based on behavioural, morphological, physiological and ecological traits of ant species. Such a framework will help facilitate the development of effective management strategies for mitigating ant invasions via active hitchhiking on vehicles.
