Using adult human cells to produce novel multicellular organisms, researchers find that the cells express both ancient genes, which are shared with our predecessors as far back as single celled organisms, and embryonic genes. They also reverse age-related modifications to DNA. The studies may lead to insights into regenerative medicine

In recent years, low-dimensional materials have become a hot spot for nonlinear optics research due to their unique electronic structure and optical properties. However, how to achieve more significant nonlinear optical responses in low-dimensional materials and actively modulate their properties remains an important challenge in current research. To this end, researchers have explored various strategies such as electric field modulation, excitation resonance and heterostructure construction to enhance the ultrafast nonlinear optical response of materials.

Polarons, as quasiparticles formed by the strong interaction between carriers and lattice vibrations, can significantly modulate the band gap, carrier mobility, diffusion, composite and other properties of functional materials, which has become a research hot research topic in recent years. Soft lattice lead halide chalcogenides exhibit strong electron-phonon coupling effects due to their unique polarity and dynamic disorder, which provides an ideal environment for the formation of this polarons. Polarons can also achieve the modulation of the optical properties of materials, such as the formation of polarons can promote the efficient upconversion of photons. However, the direct correlation between polaronic states and nonlinear optical response of low-dimensional has not been fully investigated.

A novel time-division MIMO technology enables phased-array receivers to operate faster with exceptional area efficiency and low power, as reported by researchers from Institute of Science Tokyo. The proposed system significantly reduces circuit complexity for 5G and 6G networks, including non-terrestrial nodes, by reusing signal paths through fast switching. It demonstrated a record-setting 38.4 Gbps data rate across eight streams in a 65 nm CMOS integrated circuit.

“Although it is known that Alzheimer’s disease can start up to 20 years before the first symptoms appear, the lack of knowledge about how it progresses prevents the development of effective treatments, as well as a clear diagnosis to confront this neurodegenerative disease, which origin is also unknown.” This is pointed out by the researcher at the UMA David Baglietto, specializing in the study of risk factors –namely, genetic, environmental and lifestyle– influencing on the onset and progression of this pathology.
