Multiferroics are materials that exhibit more than one prominent “ferroic” property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic states with electric fields or vice versa, due to an effect known as magnetoelectric coupling.
What really happens in the quantum world?
In this conversation, physicist Sean Carroll explores some of the deepest mysteries in quantum mechanics: the famous double-slit experiment, wave function collapse, the Many Worlds interpretation, entropy and the arrow of time.
Speaking to New Scientist reporter Jacklin Kwan, Carroll discusses why electrons appear to behave like waves, how observation seems to affect reality and whether the universe constantly branches into countless parallel worlds. Carroll also explains the measurement problem, the challenges of interpreting quantum theory and why physicists still debate what quantum mechanics is actually telling us about the nature of reality.
Carroll is a theoretical physicist, cosmologist and author whose work focuses on the foundations of physics, quantum mechanics, cosmology and the nature of time.

NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways. The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth.
Fourteen years ago, I sat down with an Italian engineer who gave his novels away for free.
Marco Santini was not chasing royalties. He was chasing readers.
His book The Alpha Centauri Project imagines the 24th century split three ways: humans, artificial intelligences, and souls, the digitized minds of people who refused to stay dead. Their interests do not align. Their futures collide. An interstellar voyage becomes the only way to avoid a war.
It reads like a thriller. It lands like a warning.
What stayed with me was not the plot. It was his stance on the future.
Pessimistic scenarios can always exist. With rationality, optimistic ones can be created.
Discover the groundbreaking world of lab-grown organs in our latest YouTube Shorts! In “Lab-Grown Organs: Revolutionizing Transplants,” we explore how scientists are utilizing bioprinting, scaffold tissue engineering, and induced pluripotent stem cells to create functional organs like kidneys, livers, and hearts. This innovative approach not only eliminates transplant waiting lists but also uses a patient’s own cells, reducing the risk of rejection. Join us as we unveil the future of organ transplantation and the incredible advancements in organogenesis!

Neuromorphic computing is a computing approach that mimics how the human brain works. Our gray matter is a marvel of nature, capable of handling huge volumes of data with incredible energy efficiency. While modern AI hardware is becoming better at processing complex tasks, it consumes vast amounts of energy.
One of the promises of neuromorphic computing is that it places memory and processing in the same location, using far less energy than traditional AI chips. However, even the most sophisticated neuromorphic systems are fairly simple and don’t come close to matching the number of connections among human neurons.
But a new study published in the journal Science Advances suggests that by using sound waves instead of electricity, hardware can better mimic the parallel processing of neurons with even greater efficiency.
