TOPIC DOSSIER // Astrophysics
A reading guide connecting galaxy shapes, surviving dust, early disk dynamics and black hole activity, with limits on what each reveals about the past.
TOPIC DOSSIER // Astrophysics
A reading guide to six selected papers on lensing impostors, stellar tracers, proposed spectroscopy, decaying halos and primordial black holes.
TOPIC DOSSIER // Economics
A reading guide to six selected theory preprints connecting information design, AI-assisted signaling, risky choice and auction equilibrium.
CHANNEL // 01 [432]
Research into artificial intelligence and intelligent systems.

Source published
The BEAKER benchmark tests multimodal AI models on laboratory images and videos, finding particular difficulty with precise interaction points and trajectories. Its offline scores do not establish whether a robot can perform experiments.

Source published
A preprint evaluates AI agents on 56 research tasks, checking numerical results and scientific manuscripts. The strongest configuration passed 27.4% of its designated trials, while an expert audit also found evaluation errors.

Source published
An Apple research preprint reports that a simulation-trained humanoid completed 91% of 360 single-task trials in six unfamiliar real environments, but struggled more with sequences of actions.
CHANNEL // 02 [62]
Research into plants, their biology, and their environments.

Source published
A preprint reports far more mature embryos from one hybrid fir culture grown with maltose rather than sucrose, alongside earlier accumulation of raffinose. The sugar patterns offer clues to maturation, but do not establish its mechanism or guarantee normal seedling development.

Source published
A Bayesian model fitted to simulated wheat growth separated genetic, environmental and interaction effects. Growth timing and curve shape showed relatively little genotype-by-environment interaction, while the final biomass level showed much more. Real-world prediction and breeding benefits remain untested.

Source published
A non-peer-reviewed preprint ranks 11 Hibiscus mutabilis cultivars using measurements and expert-selected priorities. Three lead the scoring system, but the results do not establish food safety, nutritional benefits or consumer acceptance, and conflicting descriptions need clarification.
CHANNEL // 03 [191]
Research into economic systems, decisions, and policy.

Source published
A lithium supply-chain model predicts that transferring Chinese stakes in overseas producers to local owners would barely change global output while leaving trade routes open. Banning ore shipments to China would instead cut modeled lithium supply by 25.36%, because other refineries cannot fully replace Chinese production at existing capacities.

Source published
A theoretical study explains how grouping time-series observations into patches changes the forecasting patterns a fixed number of attention heads can represent and the difficulty of learning them. Balanced patches can reduce estimation complexity, but the paper’s theory and simulations show why a square-root patch rule is a reference point rather than a universal optimum.

A rural Bangladesh study combines household valuations with the costs of a real water network. Its model favors free connections, but depends on assumptions about demand and local costs.
CHANNEL // 04 [90]
Research into stars, galaxies, cosmology, planets, and the physics of the universe.

Source published
An unreviewed preprint proposes measuring gravitational lensing flexion from changes in galaxy brightness. Simulations show promise for weak distortions, alongside unresolved biases in stronger lensing.

Source published
New measurements of 74 Milky Way Type II Cepheids suggest that their chemical composition has a modest effect on their use as distance indicators, though the size of that effect remains uncertain.

Source published
An unreviewed comment argues that a recent Hubble constant estimate combines ZTF supernova observations with SH0ES calibrators without establishing a shared brightness scale. The authors identify missing calibration products and detector corrections, while distinguishing these concerns from ZTF-only studies that do not require an absolute brightness reference.
