A Bose–Einstein condensate has been created from sodium–rubidium polar molecules by suppressing the collisions that usually remove them during cooling. It also produced a self-bound droplet with open questions. doi.org/dq67mm

Sea turtle remains from Curaçao and Bonaire indicate green turtles, hawksbills, and loggerheads have nested there since at least CE 1040. That long baseline could help guide beach protection as development expands. doi.org/hcc4mb

Ordinary video recordings can measure how children imitate simple body movements, bringing autism-related motor imitation assessment closer to a scalable, objective tool. It is meant to complement clinical evaluation. doi.org/hcc4k9

In 106 healthy adults ages 40–85, higher trait curiosity was linked to more education and mentally stimulating hobbies, but not to stronger memory, attention, or processing-speed scores. doi.org/hcc4k8

Across nearly 670,000 trials, 13 LLMs performed near chance on source and truth discernment, relying on source popularity about twice as much as source reliability. doi.org/hcc4k7

An estimated 2,000 to 5,000 metric tons of uranium may have left the DRC embedded in cobalt-hydroxide shipments from 2000 to 2024. Less than 10% appears to have been publicly declared.

In a 12-veteran pilot trial for severe, treatment-resistant PTSD, 75% were in remission one month after psilocybin-assisted therapy. No serious adverse events occurred, but the study had no control group.

Around 10 billion years ago, a dwarf galaxy collided with the young Milky Way. Gaia data helped trace how that merger left stars in the halo and helped create the galaxy’s puffed-up disk.

Economic inequality was the clearest predictor of pandemic outcomes in COVID and AIDS, while technical readiness showed no association. The paper argues preparedness should be rethought around that gap. doi.org/hcc362

Typical deviations were only 1–8% of model spread as RIME-X reproduced regional climate and impact distributions from full model ensembles. It generates probability ranges instead of a single projection. doi.org/hcc32g

In a polluted Mediterranean port, 91.7% of transplanted chicken liver sponges survived 455 days and reproduced asexually. Three other tested species shrank and died.

Mechanical strain can make a non-chiral crystal left- or right-handed on demand. Tensile and compressive strain produce opposite handedness, and the effect is reversible. doi.org/hcc3kw

New hydrothermal vents near Milos indicate that fluid flow intensity shapes both microbes and seafloor minerals. Diffuse seepage is linked to pyrite; vigorous acidic venting is linked to elemental sulfur. doi.org/hcc3kv

Lake ice loss may speed up sharply after winter temperatures cross critical thresholds. Across 724 Northern Hemisphere lakes, sensitivity to warming increased by up to 22-fold. doi.org/hcc3js

A scalable methanol-based process converted kraft lignin into benzylamines. Methanol was the most efficient solvent, while catalysts mainly changed product mix rather than yield. doi.org/hcc3jr

Across 47 trials involving 6,230 people, oral antihistamines added to eczema treatment likely offered only clinically unimportant relief for eczema and itch. Some may increase drowsiness and treatment stopping.

A 30-million-year-old Mesocyon fossil from Oregon is one of North America’s most complete pre-Ice Age dog skeletons. It is missing only the tail and parts of the hands and feet. doi.org/hcc3jq

Sheep teeth from medieval Dzhankent suggest flocks were bred across much of the year, likely helping extend milk and preserved dairy through winter in a harsh arid landscape. doi.org/hcc3jp

Stable-GFlowNet uncovered 134 unique attack types in generative AI, versus 17 from an existing GFlowNet-based method, while maintaining a 92% attack success rate. doi.org/hcc3jn

Two 40,000-year-old bird figurines from Hohle Fels are just 2 centimeters long, making them the smallest known from this period while still preserving detailed eyes, beaks and feathers.
