England’s new market for biodiversity offsets is directing planned work toward a small number of habitat types, with neutral grassland making up 44% of planned habitat. But only about 2% of the registered offset area had been sold after 16 months.
A machine-learning study predicts that 15% to 23% of uncultivated microbes may have symbiotic lifestyles. These predicted symbionts appear across half of all known bacterial and archaeal groups, according to a new genomic catalog.
A study of East European queer migrants in Scotland before Brexit examined how migration status and social class shaped couples’ access to LGBTQIA+ family rights. Mixed-status couples faced difficult borders and had to work toward legal recognition, while EU migrant couples generally benefited from greater mobility rights.
A whole-brain model of 90 anatomically connected regions produced a wider range of activity patterns when each region included interacting excitatory and inhibitory cell populations. The researchers also found that the brain’s modeled wiring helped produce fast gamma rhythms whose amplitude changed with slower rhythms.
A meta-analysis found that fine-particle concentrations around cement plants had a weighted average of 20.76 micrograms per cubic metre, above the World Health Organization’s annual guideline of 5 micrograms per cubic metre. The researchers cautioned that the studies differed substantially, including in how long they sampled the air.
This review examines pancreatic cystic lesions, especially intraductal papillary mucinous neoplasms (IPMNs), and how imaging may help distinguish them from other cysts. It discusses signs associated with cancer arising from an IPMN and the possibility of a separate pancreatic cancer developing elsewhere in the pancreas. The article is a review, not a new study of a defined group of patients.

A study mapped where gillnet fisheries and 13 cetacean species occur in Brazil’s Santos Basin. Guiana dolphins, franciscanas and bottlenose dolphins showed the greatest spatial overlap with the fisheries, highlighting areas for bycatch monitoring and management.
Migration can make populations more similar, but its effect on culture depends on how people adopt common behaviors or beliefs. A simulation found that strong conformity can preserve or increase cultural differences, especially when migration is limited.
A practitioner-designed, five-day course was associated with investigators using more science-based interviewing and interrogation tactics. After training, those tactics were linked to greater cooperation, information disclosure and admissions or confessions from suspects.
A study of spring, river, volcanic vapor and underground heated waters at Japan’s Kussharo Caldera found that hot-spring water includes water from the subducting Pacific Plate. The finding provides direct evidence linking volcanic water beneath the caldera to the slab, alongside water from rainfall and other surface sources.

Researchers developed a drone-based system that recognized American Sign Language gestures with 98.63% accuracy on a combined dataset. The system is designed to support sign-to-speech and speech-to-sign communication where fixed cameras or other communication infrastructure are unavailable.
An AI system designed for damaged South Indian palm-leaf manuscripts reported 97.4% word accuracy and 98.6% character accuracy on an archival corpus of 1,250 folios. It also reported 99.4% accuracy in identifying authentic palm-leaf manuscripts.

A cluster-randomized trial in India studied 1,507 adults with heart failure with reduced ejection fraction. Compared with usual care, a nurse-coordinated program supported by mobile health tools was associated with more days alive and out of the hospital and fewer deaths during two years of follow-up.
Researchers reviewed human reports on electroconvulsive therapy for catatonia associated with Down syndrome regression disorder. Across 27 patients from one five-person case series and 14 earlier studies, reported catatonia scores were lower after treatment, but the evidence came from small, uncontrolled reports and shows an association rather than proof of cause.

Maize varieties responded differently to beneficial soil fungi, but mixtures of varieties produced more biomass and captured more phosphorus than single-variety plantings. The results suggest that combining locally adapted maize mixtures with these fungi could support more sustainable production in sub-Saharan agroecological systems.

Researchers laser-sintered lunar soil simulants into Lego-like building blocks that can be rearranged without extra joining material. The proof-of-concept blocks reached a peak compressive strength of about 3.4 MPa.
Researchers describe how a refractive-index boundary moving at the speed of light could trap weak light in time rather than in a fixed region of space. The approach could store, compress and reshape very weak pulses, including single photons, while allowing controlled release through a one-way channel.
Researchers developed and tested a model for using compressed gas to carry rock chips out of a deep borehole on Mars. The model showed reasonable agreement with vacuum and full-system experiments, offering guidance for drilling into buried ice deposits.
Researchers report a nickel-iron catalyst that sustained water electrolysis for more than 3,400 hours at an industrial current density. The reported hydrogen production cost was $2.28 per kilogram, below the European Commission’s 2030 target.
A study in Nature Communications found that many imine reductases and reductive aminases can make chiral amines from equal amounts of the starting materials. Screening and an AI system helped identify enzymes with broad activity, and selected reactions produced gram quantities of optically pure products.
Researchers developed Orbformer, an AI model that learns transferable descriptions of molecules from 22,000 structures, including molecules with breaking bonds. After fine-tuning, it reached chemical accuracy on established tests and more demanding bond-breaking and Diels–Alder reaction problems, while reducing the need to solve each new molecule from scratch.
A new manganese-based flow-battery design reached a specific capacity of 156.2 ampere-hours per litre of catholyte, a 409% increase over reported manganese sulfate electrolytes. The battery also operated stably at a current density 30 times higher than that reported for manganese-based semi-solid flow batteries.
A laser-treated, glassy layer at the electrolyte interface improved the stability of solid-state lithium-metal batteries. In tests, the cells cycled for more than 2,000 hours, while lithium-cobalt-oxide cells retained a capacity of 101.9 mAh per gram after 800 cycles at 4.5 volts.
Neuromorphic computing is moving toward larger, more programmable systems that process information in ways inspired by the nervous system. A review of recent work suggests these computers may be useful for low-power, real-time tasks at the edge, while major challenges remain in training, testing and manufacturing.

A study of three nationally representative US surveys finds that many Americans feel similarly about both major parties. These people fall into two groups—one lukewarm toward both parties and one cold toward both—with different reported attitudes toward and participation in democracy.
