BEAKER benchmark reveals a gap between understanding lab scenes and locating where to act
Source published
An expert-curated benchmark tests 28 multimodal AI models on chemical laboratory images and videos. The preprint reports stronger performance on coarse procedural understanding than on precise spatial grounding, but its offline results do not establish real-world robotic capability.

FrontierPhysics tests whether AI agents can complete physics research—not just solve problems
Source published
A preprint introduces 56 research tasks spanning nine physics domains, grading both numerical correctness and scientific manuscripts. The highest-scoring configuration passed 27.4% of attempts, while an expert audit identified weaknesses in rigorous reasoning and expert intuition—and errors in the evaluation itself.

GBPNet learns to improve error correction while keeping a classic decoder’s structure
Source published
A preprint by Samira Malek introduces GBPNet, a neural decoder that adds learned processing to belief propagation. The paper reports lower bit error rates across several tested linear codes, but does not establish hardware speed, energy efficiency or performance beyond its simulated channel setting.

Palm flower shapes offer clues, not clear boundaries, to Peruvian species
Source published
A preprint analysing 549 female flowers from 11 Peruvian palm species finds that combining calyx and corolla shapes improves species assignment, but extensive overlap and conflicting statements within the manuscript limit firm taxonomic conclusions.

Two flowering regulators help limit woody tissue in tomato stems
Source published
A tomato preprint identifies FUL2 and STM3 as brakes on secondary xylem accumulation. Knockout plants developed more xylem in older stems, while gene-expression responses varied with stem position and development rather than age alone.

The Missing Silicon in a Diatom’s Glass Workshop
Source published
A bioRxiv preprint combines fluorescence imaging, cell fractionation and silicon NMR to investigate how diatoms supply material for their silica walls. It finds evidence for a separable intracellular silicon fraction, but does not establish whether cells use that fraction as a reserve.

Changing lithium ownership may not secure supply, model suggests
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.

Why free water connections can cost less per household
Source published
A rural Bangladesh study combines incentivized household valuations with the costs of a real water network. Its model finds that free connections minimize public spending per connected household, though demand estimates and local conditions limit the conclusion.

When College Choices Create Congestion, Clearing the Queue Can Come at a Cost
Source published
A model of Cambridge college applications finds that random assignment eliminates valuable choice, while a simulated rent increase at two popular colleges produces uneven gains and losses.

Dust in Quiet Galaxies May Reveal How Their Star Formation Shut Down
Source published
ALMA observations of 13 gravitationally magnified galaxies reveal striking differences in their dust content. A new preprint suggests that gentler shutdowns of star formation may allow dust to persist or be replenished, but hidden star formation remains an alternative explanation for the dustiest systems.

GetGaia 2.0 separates stellar companions from the Milky Way foreground
Source published
A new preprint describes software that automatically identifies likely members of dwarf galaxies and star clusters in Gaia data and measures their collective motion. Tests recover 55 dwarf-galaxy fields and 93 globular clusters, although crowded backgrounds, overlapping populations and faint stars impose important limits.

CosmicGrain follows dust’s individual histories through a simulated galaxy
Source published
A new preprint introduces CosmicGrain, a simulation module that lets dust move independently of gas and records how grains grow, erode and fragment. Its experiments highlight gas drag’s role in retaining dust, but ineffective supernova-shock destruction and resolution-sensitive results limit quantitative conclusions.
