In a landmark achievement, an international team of researchers has successfully engineered the world’s first ideal Weyl semimetal, a quantum crystal that exhibits exotic electromagnetic properties. This innovative material, synthesized from a topological semiconductor, hosts a single pair of Weyl fermions without any irrelevant electronic states, paving the way for potential applications in terahertz devices, high-performance sensors, and low-power electronics.
The discovery, published in Nature, marks a major milestone in the decade-long pursuit of quantum materials, where researchers have been hindered by the presence of undesired electrons that obscure the unique properties of Weyl fermions. By revisiting a theoretically proposed strategy from 2011, the team has created a semimetal with a vanishing energy gap, enabling it to absorb low-frequency light and unlocking new possibilities for optoelectronics and quantum technology.
New research from the Academy of Military Medical Sciences in Beijing has uncovered a rather intriguing finding: natural melanin nanozymes (NMNs) derived from octopus ink may potentially slow ageing, protect against neurodegenerative diseases, and extend lifespan. Published in ACS Omega, the study reveals how these nanozymes work at the cellular level to mitigate oxidative stress, improve gut health, and enhance brain function, offering a new frontier in anti-ageing and neurological research.
What are Melanin Nanozymes?
Melanin, best known as the pigment responsible for skin and hair colour, has also been recognized for its potent antioxidant properties. Nanozymes created from natural melanin, like those extracted from octopus ink, mimic the activity of antioxidant enzymes such as superoxide dismutase (SOD). These nanozymes neutralize free radicals, reduce oxidative stress, and improve cellular health—processes that are critical in mitigating ageing and the onset of neurodegenerative diseases.

Many of the strongest limitations on our technology and civilization at this time are from problems moving energy around with us, in a way which is light, energy dense, and cheap. Today we’ll look at some ways we might increase that vastly, and challenges to do that and the impact such dense portable power would have.

Could you travel back in time through a wormhole? Neil deGrasse Tyson sits down with theoretical physicist and Nobel Laureate Kip Thorne to reflect on discovering gravitational waves with LIGO, the science in the movie Interstellar, black holes, and many more mysteries still yet to be answered.
Discover the origin story of the movie Interstellar on its 10th anniversary. Kip explains how science, not fiction, shaped the film’s narrative—from the colossal waves on Miller’s planet to the physics behind black hole time dilation. Discover the recipe for how to create a wormhole and how turning on a time machine could cause it to self-destruct. Plus, learn about the Casimir effect, exotic particles, and how LIGO manipulated vacuum fluctuations to bypass the uncertainty principle.
Neil and Kip dig into the origins of gravitational wave detection, tracing its roots to Joe Weber’s early experiments and Ray Weiss’s unpublished paper. Kip reflects on the decades of work required to make LIGO a success, the challenges of measuring distortions a fraction of a proton’s width, and the historic detection of gravitational waves in 2016 that confirmed Einstein’s predictions.
Why don’t quantum physics and the theory of relativity mix? We discuss the mysteries of quantum gravity, the paradox of black hole information loss, and Kip’s legendary bet with Stephen Hawking and John Preskell. Kip explains why backward time travel may be possible, Hawking Radiation, and theories for why information can be lost. As they explore the intersection of science and art, Kip discusses his passion for storytelling and some of his future projects, from his poetry-art collaborations to documenting the history of LIGO.
How do particles get mass? Neil deGrasse Tyson and comedian Chuck Nice discover squarks, sneutrinos, the Higgs boson, and whether dark matter has a particle with theoretical physicist Brian Greene.

Can we finally get to the bottom of what happens when a quark falls into a black hole? Learn about the ultraviolet catastrophe, the start of quantum physics, and Max Planck quantizing packets of energy. We also discuss how Einstein won the Nobel prize for the discovery for which he is least famous.
We take a deep dive into the Higgs boson. Who’s Higgs? What’s a boson? Find out about how the Higgs field creates mass, the different quantum particles, and how quarks create protons and neutrons. Brian breaks down the theory of supersymmetry: does every particle have a counterpart? Learn about squarks, sneutrinos, and whether supersymmetry can give an answer to what dark matter is.
Is the fabric of spacetime woven by tiny wormholes? Discover the Casimir force, quantum fluctuations, and why you need so many dimensions in a string theory universe. We discuss whether the cosmological constant is, in fact, constant. Plus, find out about the biggest mismatch between theory and experiment in physics.
Could we create warp drive someday? In this Star Trek-themed episode, Neil deGrasse Tyson and co-host Chuck Nice team up with astrophysicist Charles Liu to dive into the science, technology, and legacy of one of the most influential sci-fi franchises of all time: Star Trek.
We answer questions about quantum entanglement, the size of electrons, and the real science behind Trek tech or Treknology. How close are we to warp drives, transporters, and subspace communication? You might be surprised to hear what’s theoretically possible and what remains in the realm of science fiction.
We discuss technology that exists already and the solutions to storytelling challenges through warp drives and dilithium crystals. Learn about the show’s physics, from phasers and antimatter to the mycelium network’s fascinating parallels with fungal biology. How do you store antimatter without it annihilating? Plus, find out who everyone’s favorite characters are and who they relate to most.
As we reflect on the series’ 23rd-century vision, we ask: Could humanity achieve Trek-level tech by 2260? We discuss the physics we’re missing and the collective imagination and determination it takes to advance our understanding of the universe.
