Dyson’s most overengineered gadget may have a waterproofing problem
There's always a danger in over-complicating products. Simple is so often best. The apocryphal story of NASA spending millions crafting a space pen while Soviet cosmonauts used a pencil is often cited as a prime example, even if it's actually not true. Perhaps it's not surprising that Dyson has got into hot water trying to reinvent the electric toothbrush. The Chinese invented the first bristle toothbrush during the Ming dynasty. That concept muddled along quite nicely until 1937, when Tomlinson Moseley filed a patent for the earliest electric toothbrush.
Multi-Stage and Multi-Field Inflation in Random Inflationary Landscapes
Generic potentials in an inflationary landscape are typically too steep to support a prolonged period of cosmic inflation. Atypical flat regions of the landscape are required to support successful inflation. The occurrence of such regions leads broadly to two possibilities: a single prolonged period of slow-roll inflation (which we call single-stage inflation), or multiple shorter periods of inflation separated by transient departures from slow roll (which we call multi-stage inflation), giving
Nucleosome simulations suggest mechanisms of electrostatically-driven mesoscale chromatin evolution
Nucleosomes are structures made up of proteins called histones that bind and compact DNA, driving the mesoscale organization of the chromatin polymer. Although histone proteins have diversified over evolutionary time, their contributions to the corresponding diversification of chromatin structure are poorly understood. Here, we mine protein databases for histones and create \emph{in silico} nucleosomes for 3241 organisms spanning $>$1.5B years of evolution. Using a combination of electrostatic c

Don't mind the gap: Absolutely Continuous Edge Spectrum in a Mobility Gap
We study the edge spectrum of two-dimensional lattice Hamiltonians and magnetic Schrödinger operators in a mobility gap, an energy interval in which the bulk spectrum is potentially localized rather than necessarily absent. Under suitable localization and boundary assumptions, we prove that a constant nonzero bulk topological index implies that the entire interval belongs to the absolutely continuous spectrum of the corresponding half-space operator. The absolutely continuous spectral multiplici
Experimental evidence of generalization in quantum machine learning in small-data regime
Quantum machine learning is a promising paradigm for learning from limited data, a central bottleneck in domains such as medical imaging, clinical trials, and rare diseases. Quantum convolutional neural networks (QCNNs) are particularly attractive in this setting, combining a hierarchical architecture with strong inductive bias and a parameter count that grows only logarithmically with system size. Their appeal rests on the generalization bounds of Caro et al. (2022), which show that the general

Trump’s sneaky plan to gut Endangered Species Act draws from 1995 Scalia dissent
Last week, The New York Times reported that an internal memo had been quietly distributed across US Fish and Wildlife Service (FWS) field offices, directing staff to radically reinterpret the Endangered Species Act (ESA) in a move that blindsided conservationists. Staffers were essentially asked to start looking the other way when private interests cause preventable deaths of vulnerable animals.

Critical-State RL: Diagnosing Trainable States for Multi-Turn Tool Use
Multi-turn tool-use failures can hinge on a single model call, yet reward variation alone does not reveal which call would benefit from training. When rewards depend on later interactions, their variation can reflect downstream randomness rather than differences between the current actions. We introduce Critical-State RL to identify trainable states in multi-turn interactions. Given task-defined candidate calls and local rewards, the method assesses whether each reward captures the action's effe

Shuffling the deck chairs: Xbox continues its "reset" with dramatic restructuring
When Xbox announced sweeping layoffs in July as part of a brutal "reset" for the gaming brand, Xbox CEO Asha Sharma said part of the pre-existing problem in the gaming unit was "teams, studios, and functions [that] often operate independently, [making it] harder to work toward a shared goal." Today, the company announced a radical restructuring of its internal studios that is seemingly designed to reduce that "independence" for the teams behind some of gaming's biggest franchises. The biggest apparent change is for the Halo franchise, which will now be under the remit of Call of Duty maker Act

Statistical Fluctuations as Primordial Correlators in the CMB: Finite Chemical Potential Thermodynamics
Can primordial cosmological correlations originate from statistical fluctuations of an early-universe thermal system? We connect grand-canonical thermodynamics, stochastic transport, and gauge-invariant cosmological perturbations for a charged fluid at finite chemical potential. Energy-charge susceptibilities determine curvature, charge-isocurvature, and cross-correlation amplitudes, while transport sets when each mode leaves equilibrium. For an isolated, adiabatic conformal plasma with conserve
Towards Accurate Prediction of Mutation-Induced Changes in Protein Structure
Proteins can possess numerous mutations relative to their wild-type amino acid sequences with minimal impact to their structure and function. However, in other cases, even a single amino acid mutation relative to the wild-type sequence can lead to a large change in structure or even a disease phenotype. While the accuracy of wild-type protein structure prediction has improved significantly in recent years, it remains difficult to accurately predict the structure of mutant proteins. Here, we char
