Summary: Researchers made a significant discovery in the study of human brain evolution, identifying epiregulin as a key factor in the expansion of the human neocortex. By comparing brain development between mice and humans and utilizing 3D brain organoids, the team found that epiregulin promotes the division and expansion of stem cells, crucial for neocortex development.

This study, which utilized cutting-edge 3D culture technology, suggests that the quantity of epiregulin, rather than its presence or absence, distinguishes human brain development from that of other species, including primates like gorillas. The research offers new insights into what makes the human brain unique and underscores the value of innovative methodologies in understanding complex evolutionary processes.

Star Trek: The Next Generation looks at sentience as consciousness, self-awareness, and intelligence—and that was actually pretty spot on. Sentience is the innate human ability to experience feelings and sensations without association or interpretation. “We’re talking about more than just code; we’re talking about the ability of a machine to think and to feel, along with having morality and spirituality,” Ishaani Priyadarshini, a Cybersecurity Ph.D. candidate from the University of Delaware, tells Popular Mechanics.

💡AI is very clever and able to mimic sentience, but never actually become sentient itself.

Neurotech startup Paradromics is set to commence human trials of its brain implant in 2025, intensifying the competition in the emerging brain-computer interface (BCI) market.

This move positions Paradromics against Elon Musk’s Neuralink, which has been at the forefront of public attention in this domain.

Paradromics’ CEO and founder, Matt Angle, in an interview with CNBC Tech, expressed his enthusiasm about the potential of brain-computer interfaces.

Development of a cognitive enhancer based on preclinical findings has translational potential (Stepan et al., in 30 April 2024 issue).

Imagine waking up one day to the realization that everything you’ve ever known—the universe, the stars, your own thoughts—could be nothing more than an elaborate computer simulation crafted by an advanced civilization. This is the audacious, mind-bending premise explored by philosopher Nick Bostrom in “Are You Living in a Computer Simulation?”. Through rigorous reasoning and a blend of cutting-edge technology and philosophical inquiry, Bostrom challenges our understanding of reality itself, posing that the odds we are living in a simulated world may be profoundly higher than we ever considered. As you delve into this thought-provoking investigation, you might just find that questioning the nature of your own existence becomes more thrilling—and unsettling—than any work of science fiction.

Magnetization can be switched with a single laser pulse. However, it is not known whether the underlying microscopic process is scalable to the nanometer length scale, a prerequisite for making this technology competitive for future data storage applications. Researchers at the Max Born Institute in Berlin, Germany, in collaboration with colleagues at the Instituto de Ciencia de Materiales in Madrid, Spain, and the free-electron laser facility FERMI in Trieste, Italy, have determined a fundamental spatial limit for light-driven magnetization reversal.

They report their finsings in Nano Letters (“Exploring the Fundamental Spatial Limits of Magnetic All-Optical Switching”).

Modern magnetic hard drives can store more than one terabit of data per square inch, which means that the smallest unit of information can be encoded on an area smaller than 25 nanometers by 25 nanometers. In laser-based, all-optical switching (AOS), magnetically encoded bits are switched between their “0” and “1” state with a single ultrashort laser pulse. To realize the full potential of AOS, particularly in terms of faster write/erase cycles and improved power efficiency, we thus need to understand whether a magnetic bit can still be all-optically reversed if its size is on the nanoscale.

Gold nanoparticles have been the subject of intense research for several decades due to their interesting applications in fields such as catalysis and medicine. “Surface ligands” are organic molecules typically present on the surface of gold nanoparticles. During synthesis, these surface ligands play an important role in controlling the size and shape of the nanoparticles.

For several decades, the CIC biomaGUNE team led by Ikerbasque Research Professor Luis Liz-Marzán has studied in detail the growth mechanisms and properties of these nanoparticles. Despite numerous advances that have recognized the importance of surface ligands, many questions remain about their exact behavior during and after growth. Direct observation of surface ligands and their interface with gold nanoparticles has therefore been a long-standing goal for many scientists in this field.

Transmission Electron Microscopy (TEM) is the technique most widely used to investigate nanoparticles. However, the study of surface ligands by means of TEM presents significant challenges; the reason is that the ligands are sensitive to the electron beam, their contrast is limited and their structure in vacuum differs from their native state in solution.

Researchers at the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) have demonstrated that under specific conditions, humans can treat robots as co-authors of the results of their actions. The condition that enables this phenomenon is that a robot behaves in a human-like, social manner. Engaging in gaze contact and participating in a common emotional experience, such as watching a movie, are the key.

The study was published in Science Robotics and paves the way for understanding and designing the optimal circumstances for humans and robots to collaborate in the same environment.
