Major gap in Earth’s rock record likely due to tectonics—not glaciers
The Great Unconformity is a major gap in Earth’s geologic record. The missing layer between Precambrian and Cambrian rocks represents a gap of around a billion years of history. Among much debate surrounding the cause of the gap, a new study, published in the Proceedings of the National Academy of Sciences, indicates that the timing of the erosion leading to the Great Unconformity aligns with the assembly of the Columbia supercontinent, and that glaciation only contributed minimally.
The origin of the Great Unconformity is debated among geologists. Some believe evidence points to the ancient glaciation associated with “snowball Earth,” which occurred around 700 million years ago, is to blame. Others think tectonic processes associated with Columbia and Rodinia supercontinent cycles are the main cause.
The Great Unconformity was first recognized in the layers of the Grand Canyon, and many subsequent studies took place there to attempt to determine a cause. Those studies showed variable timing and mechanisms. The authors of the new study think that the evidence for Neoproterozoic-period snowball Earth glaciation causing the unconformity at such large scales is weak.
Generation of phonons with angular momentum during ultrafast demagnetization
A century ago, Einstein and de Haas observed the transfer of spin angular momentum to mechanical rotation. It remains, however, unknown how the Einstein-de Haas effect operates at ultrafast timescales and atomic length scales. The authors use here time-dependent density functional theory combined with nuclear dynamics to investigate how ferromagnetic FePt reacts when irradiated by a femtosecond laser. They find that ultrafast loss of electronic spin angular momentum leads to generation of phonons carrying angular momentum, in a transfer process mediated by spin-orbit interaction.
At our upcoming conference
we are thrilled to host Joscha Bach at Future Day 2026 – he is a leading voice in cognitive architectures and the founding director of the California Institute for Machine Consciousness. Bach’s talks are famous for being mind-bending journeys that challenge fundamental assumptions about reality and agency. In his upcoming session, he will dive into the Machine Consciousness Hypothesis, offering a glimpse into how we might one day create truly sentient digital minds.
Joscha Bach – The Machine Consciousness Hypothesis.
What if our consciousness is not a ‘thing’ we have, but a simulation our brain runs to make sense of itself?
Twisting optical fiber creates a robust new pathway for light
Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University of Cambridge and international partners—has developed a new structure that keeps light flowing smoothly even through bends, twists or damage, with the potential to operate over unprecedented distances.
