Researchers from Tokyo Metropolitan University have created nanostructured alumina surfaces which are strongly antibacterial but can be used to culture cells. They found that anodic porous alumina (APA) surfaces prepared using electrochemistry in concentrated sulfuric acid had unprecedented resistance to bacterial growth, but did not hamper cell cultures.

The work is published in the journal Langmuir.

The team’s technology promises to have a big impact on regenerative medicine, where high quality cell cultures without bacterial contamination may be produced without antibiotics.

Using a supercomputer, scientists have found that the matter of neutron stars with high isospin densities is superconducting.

The once shiny, exciting use cases for quantum technology may turn out to be pretty mundane if a small, but courageous band of researchers proves their theories correct. After all, using quantum computers to find new drug treatments, navigate the world without global positioning systems, and optimize complex portfolios may seem downright boring compared to using them to explore the myriad of questions that surround the hard problems of consciousness. Questions like: what the heck even is consciousness — and, does it have a connection to quantum mechanics? And, can quantum computing help make robots conscious — and should we make them conscious?

Tough questions, for sure, but here we’ll introduce a few researchers and entrepreneurs who are heading in that direction right now and leaning into what might turn out to be the ultimate quantum computing use case of all time: consciousness.

Hartmut Neven, a physicist and computational neuroscientist leading Google’s Quantum Artificial Intelligence Lab, believes quantum computing could help explore consciousness. Speaking to New Scientist, Neven outlined experiments and theories suggesting consciousness might emerge from quantum phenomena, such as entanglement and superposition, within the human brain. He proposes leveraging quantum computers to test these ideas, potentially expanding our understanding of how the mind interacts with the physical world.

Imagine a future where your phone, computer or even a tiny wearable device can think and learn like the human brain—processing information faster, smarter and using less energy.

A new approach developed at Flinders University and UNSW Sydney brings this vision closer to reality by electrically “twisting” a single nanoscale ferroelectric domain wall.

The domain walls are almost invisible, extremely tiny (1–10 nm) boundaries that naturally arise or can even be injected or erased inside special insulating crystals called ferroelectrics. The domain walls inside these crystals separate regions with different bound charge orientations.

Stress disrupts memory precision, causing generalized fear responses by enlarging memory-encoding neuron networks. This effect, mediated by the brain’s endocannabinoid system, suggests potential therapeutic targets for conditions like PTSD and anxiety disorders.

Quantum computers may soon dramatically enhance our ability to solve problems modeled by nonreversible Markov chains, according to a study published on the pre-print server arXiv.

The researchers from Qubit Pharmaceuticals and Sorbonne University, demonstrated that quantum algorithms could achieve exponential speedups in sampling from such chains, with the potential to surpass the capabilities of classical methods. These advances — if fully realized — have a range of implications for fields like drug discovery, machine learning and financial modeling.

Markov chains are mathematical frameworks used to model systems that transition between various states, such as stock prices or molecules in motion. Each transition is governed by a set of probabilities, which defines how likely the system is to move from one state to another. Reversible Markov chains — where the probability of moving from, let’s call them, state A to state B equals the probability of moving from B to A — have traditionally been the focus of computational techniques. However, many real-world systems are nonreversible, meaning their transitions are biased in one direction, as seen in certain biological and chemical processes.

Some 275 million light-years from the Milky Way lies a true cosmic mystery.

There, in the heart of a galaxy named 1ES 1927+654, squats a supermassive black hole whose monkeyshines and hijinks have baffled astronomers for years.

The Perfect Cosmic Fireball

Astronomers have unveiled the extraordinary details of a nearly perfect spherical explosion—a kilonova—caused by the collision of two neutron stars. This dramatic event unfolded in 2017 in the galaxy NGC 4,993, located 140–150 million light years from Earth in the Hydra constellation. With a combined mass of 2.7 times that of the sun, the neutron stars had orbited each other for billions of years before their explosive merger.

Lead researcher Albert Sneppen of the Cosmic Dawn Center described the event as “a perfect explosion” due to its symmetry and scientific implications. The kilonova’s luminous fireball emitted a light equivalent to a billion suns for several days, dwarfing any earthly nuclear explosion in intensity.
