RoboAICon2023: Robots that read emotions

Robots are becoming more adept at reading human emotions and thoughts simply by "looking" into their faces. This advancement could one day lead to more emotionally responsive machines that are able to recognise changes in a person's physical or mental health. Researchers at Case Western Reserve University claim to be advancing the artificial intelligence (AI) that powers interactive video games and will soon improve the following generation of customised robots that are probably going to coexist with humans.  Additionally, it is being done in real time by the Case Western Reserve robots.   Kiju Lee , the Nord Distinguished Assistant Professor in mechanical and aerospace engineering at the Case School of Engineering, and graduate student Xiao Liu have created new machines that can recognise human emotions nearly quickly and with 98 percent accuracy. Similar results had previously been obtained by other researchers, but the robots frequently answered too slowly. Even a

InfraCivilCon2023: System of Land Use and Transportation

Urban transportation attempts to meet the transportation needs brought on by a variety of urban activities taking place in a variety of urban contexts. Analysis of the patterns and processes in the transport-land use system is thus crucial for understanding urban entities. This system is quite complicated and involves a number of connections between the land use, spatial interactions , and transportation systems . Transport mechanism,  the group of transportation modes and infrastructures that facilitate urban freight and passenger transit. It often represents the accessibility level and is made up of supply-enhancing infrastructure. For instance, traffic assignment models infer flows within a transportation network using an existing spatial interaction structure. Consequently, conceptual flows turn into actual physical phenomena. spatial relationships , the kind, scope, sources, and destinations of urban freight and passenger flows. The characteristics of the transport system as well

MechResCon2023: Specific brain circuits can be remotely activated in less than a second thanks to new wireless technologies.

Wireless technology has been developed by a research team lead by Rice University neuroengineers to quickly and remotely stimulate particular brain circuits in fruit flies.  Researchers from Rice , Duke , Brown , and Baylor College of Medicine utilised magnetic signals to activate specific neurons that regulated the body position of freely flying fruit flies in an enclosure in a demonstration that was published in Nature Materials .                       " The scientific community is looking for instruments that are extremely precise but also minimally intrusive to research the brain or cure neurological problems. The holy grail of neurotechnologies is to use magnetic fields to remotely regulate specific brain circuits. Our research makes a significant advancement toward that end by speeding up remote magnetic control so that it is more comparable to the brain's natural pace.  Author of the paper, Rice Associate Professor of Electrical and Computer Engineering , and Parti

NanoResCon2023: Regenerative medicine may undergo a revolution thanks to new nanotechnology that quickens the process by which stem cells become bone.

Researchers at King Abdullah University of Science & Technology (KAUST) have created a nanotechnology platform that may help them discover new treatments for bone ailments. Iron nanowires that bend in reaction to magnetic fields are used in the procedure. The moving substrate provides a sort of physical workout for the bone-forming stem cells that are cultured on a mesh of these small wires. After that, they develop into adult bone far more quickly than in settings for standard culture, with a differentiation technique that takes only a few days as opposed to a few weeks. The associate professor of biology Jasmeen Merzaban calls this discovery "extraordinary." It may be possible for bone regeneration to be more effective because "we can accomplish efficient bone cell creation in a shorter length of time." Merzaban co-led the investigation with Jürgen Kosel , a sensor expert, and others from both labs. The capacity of the scientists' nanowire scaffold

MatSciCon2023: Biohybrid material is robust but flexible, performing like cartilage.

Scientists have struggled to make biomaterials that work as well as cartilage and tendons, but a novel material developed at Cornell University suggests a promising new strategy for emulating real tissue. The findings, which were made public on July 8 in the Proceedings of the National Academy of Sciences , offer a fresh method for putting together medical treatments for injured tissue.  The tissue must be malleable enough to bend and flex while tough enough to tolerate sustained loading, such as the weight that a knee tendon must bear. Collagen hydrogels and synthetic materials may be used to replace worn-out or injured tissue, but neither by itself provides the ideal blend of biological and mechanical characteristics of real tissue. Now, Cornell scientists have created a biohybrid composite material with many of the same properties as a real tissue. Collagen, which provides the substance its softness and biocompatibility , and a s ynthetic zwitterionic hydrogel , which has positiv

AeroResCon2023: Autonomous robots will 3D print the vaulted lunar outpost for NASA and AI SpaceFactory.

 LINA is a 3D printed structure that is meant to be a lunar settlement , and its design has been released by AI SpaceFactory and the NASA Kennedy Space Center . The structure, which is planned to be built on the south pole of the moon by autonomous robots, is characterised by Romanesque arches that require less material to endure enormous compressive loads. LINA's structural design will be 3D printed utilising lunar regolith and a polymer derived from Earth. LINA will be 3D printed at a 60-degree angle in contrast to traditional 3D printing, which adds layers parallel to the ground to enable construction of the vaulted roof. To give defence against radiation, micrometeorites, lunar seismic activity, and dramatic heat swings, the arches will be covered in 2.7 metres (8.8 feet) of lunar regolith. The team will use the nearly constant sunshine on the crater's peaks provided by the outpost's proximity to the Shackleton crater's rim at the lunar south pole to generate ele

RoboAICon2023: Hydrogel-based, magnetically controlled smart transformers

Researchers are creating clever soft transformers to drastically speed up research applications in the lab, much like the intelligent robots that appeared in the "Transformers" movie that could change shapes and function in many ways. Dachuan Zhang and a research team in materials science and chemical sciences in China have presented a remotely controlled soft transformer based on a shape memory hydrogel system. The paper has now been published in Advanced Intelligent Systems . By incorporating magnetite (Fe3O4) magnetic nanoparticles into a double network polymer structure of poly (N-(2-hydroxyethyl) acrylamide) containing gelatin, the research team was able to produce the hydrogel.  While the magnetite nanoparticles provided photothermal heating and magnetic manipulation functions to distort the hydrogel for navigation in a magnetic field, the reversible coil-triple-helix transformation of the gelatin component gave the hydrogel shape memory and self-healing properties.

InfraCivilCon2023: How to Make the Most of Strategic Green Spaces' Cooling Effects

One of the best and most accessible strategies to lessen the effects of rising temperatures in urban contexts is to use urban green spaces. Cities all across the world experience more frequent and severe heat waves, putting the lives of their residents at danger. Urban heat islands are created when natural land cover is replaced with surfaces that absorb and hold heat, such as pavements and buildings, and many cities are exploring methods to lessen their effects. In comparison to the surroundings, this causes the temperature to rise by a number of degrees. Cities have their own unique microclimate that is influenced by this phenomenon as well as a number of frequently disregarded elements. All elements must be taken into account for a climate plan to be effective. The sociological makeup of the city is highly connected with heat risk levels. Less access to green spaces puts communities with historically underprivileged and less affluent sectors at higher risk. The impact on the underpr

MechResCon2023: For soft robots, a new liquid metal droplet electronic device

Soft robots have many advantages, including diverse movement patterns, amicable human engagement, and adaptable actuation strategies. However, the absence of suitable practical techniques and soft controllers makes the production of a fully integrated flexible robot still quite challenging.  Using the locomotion and deformation behaviour of liquid metals (LMs) through the electrical stimulus , a team of researchers led by Prof. Jing Liu from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences proposed and demonstrated a new type of liquid metal droplet electronic device.  To do logical computing, the gadget could be further organised into gate logics. The study initially showed the importance of liquid metals in intelligent electronic control systems when it was published on March 18th, 2021 in Advanced Intelligent Systems . It also provides a fresh method for creating soft electronic gadgets. Liquid metal is a novel class of smart materials

NanoResCon2023: A "Nano-Robot" designed to study cell processes and made completely of DNA

Making a tiny robot out of DNA to explore cell processes that are undetectable to the human eye...  You could be excused for thinking it is science fiction, but it is actually the focus of significant research being conducted at the Structural Biology Center in Montpellier by researchers from Inserm , CNRS , and Université de Montpellier 1]. This extremely cutting-edge " nano-robot " could make it possible to analyse mechanical forces at microscopic scales in greater detail, which are important for many biological and pathological processes. A recent research in Nature Communications describes it. Micromechanical forces acting on our cells cause biological signals that are crucial to numerous cell processes involved in either the development of diseases or the regular operation of our bodies.  For instance, the sensation of touch depends in part on the application of mechanical forces to particular cell receptors (the discovery of which was this year rewarded by the Nobel

MatSciCon2023: Researchers studying graphene have photographed atoms "swimming" in a liquid

To better understand how the presence of liquid alters the behaviour of the solid, a team led by scientists from the National Graphene Institute (NGI) employed stacks of 2D materials like graphene to trap liquid. Their findings were published in the journal Nature. For the first time, the team was able to photograph a single atom " swimming " in a liquid. The results might have a significant effect on how green technologies like hydrogen production are developed in the future. When a liquid and a solid are in close proximity to one another, both substances adapt to the other's presence. These atomic-scale interactions at solid-liquid interfaces control the behaviour of fuel cells and batteries used to generate clean power, as well as the effectiveness of systems used to produce clean water and many biological activities. Professor Sarah Haigh , one of the principal investigators, said: "It is incredibly astounding how much we still don't understand about the pri
