When most people think of freshly poured concrete, they likely imagine a smooth, flawless surface left to dry. But a new wheeled robot is challenging that convention by driving right over wet concrete, gouging grooves into the material to strengthen it—while also reducing construction costs.

In traditional concrete construction, rebar is used to reinforce the material, providing additional strength to withstand tension. However, rebar is not only expensive but also adds significant weight to the structure. To mitigate the need for so much rebar, construction workers often manually add grooves to the surface of each layer while the concrete is still wet. These grooves increase the surface area for bonding with the next layer of concrete, which improves the shear strength at the interface, allowing for less rebar to be used.

A team of researchers in Japan has made an astonishing breakthrough that could revolutionize the fields of regenerative medicine and lab-grown meat. In a recent study published in Proceedings of the Japan Academy, Series B, the scientists have successfully created solar-powered tissues, a development that could significantly enhance the production of lab-grown organs and meat.

The groundbreaking research centers on the creation of hybrid plant-animal cells capable of harnessing energy from sunlight, just like plants. While plants use photosynthesis to convert sunlight into energy, animals rely on mitochondria for energy production. By combining plant cells with animal cells—specifically, cells taken from hamsters—the team aimed to create a new type of tissue that could produce energy from sunlight.

In a groundbreaking development, scientists have created a new “biocooperative” material derived from blood, which has shown great promise in repairing bones and could pave the way for personalized regenerative therapies. Researchers from the University of Nottingham’s Schools of Pharmacy and Chemical Engineering have harnessed the power of peptide molecules to guide key processes in natural tissue healing, creating living materials that enhance tissue regeneration. The research, published in Advanced Materials, marks a significant step forward in regenerative medicine.

Human tissues possess a remarkable ability to regenerate after injuries, especially when the damage is small. This healing process is complex and begins when liquid blood forms a solid regenerative hematoma (RH), a living microenvironment that consists of cells, macromolecules, and growth factors that work together to orchestrate regeneration. However, replicating this process in the laboratory has proven challenging due to its intricate nature.

In a groundbreaking experiment, scientists have confirmed the superfluid properties of supersolids by observing the formation of quantized vortices—mini-tornadoes in a quantum gas. This breakthrough offers new insights into the coexistence of solid and fluid characteristics in these exotic states of matter, opening up exciting possibilities for the study of quantum systems and astrophysical phenomena.

The concept of supersolids—materials that simultaneously exhibit the rigidity of solids and the fluidity of superfluids—may seem paradoxical. However, more than 50 years ago, physicists predicted that quantum mechanics could allow such a state. As Francesca Ferlaino, from the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI), explains, “A supersolid is both rigid and liquid, much like Schrödinger’s cat, which is both alive and dead.”

Controlling technology with just your mind may have once been the realm of science fiction, but advances in brain-computer interface (BCI) technology have brought it much closer to reality. Researchers at the Johns Hopkins Applied Physics Laboratory (APL) and the Johns Hopkins School of Medicine have made a groundbreaking discovery in noninvasive, high-resolution brain activity recording. In a recent paper published in Scientific Reports, the team revealed that neural tissue deformations could provide a novel signal for brain activity, one that could revolutionize future BCI devices.

Unlike current BCI technologies, which often require invasive surgical implants to record and interpret neural signals, this new approach offers a noninvasive alternative with the potential for broader applications. “Today, the highest impact BCI technologies require invasive surgical implants to record and decode brain activity,” explained Mike Wolmetz, program manager for Human and Machine Intelligence at APL. “Our findings present the foundations for a new approach that could significantly expand the possibilities for nonsurgical BCI.”
