'Hunting for treasures' with AI: Astronomers detect rare neutral atomic-carbon absorbers with deep neural network

An international team used deep learning neural networks to identify rare weak signals in quasar spectral data. They discovered 107 extremely rare neutral carbon absorbers, doubling the number of samples found in 2015, and detected more faint signals than before.

Researchers define mechanistic basis for functional heterogeneity of tumor-infiltrating B cells with therapeutic implications

A study published in Science reveals two patterns of tumor-infiltrating B cell responses: germinal center-like and extra-follicular. The former is associated with anti-tumor immunity, while the latter is linked to an immunosuppressive tumor microenvironment. Researchers propose targeting atypical memory B cells for cancer immunotherapy.

Researchers achieve electrosynthesis via superwetting organic-solid-water interfaces

Chinese scientists developed a new three-phase OSW electrocatalytic system for efficient production of high-purity benzaldehyde, achieving 97% Faradaic efficiency and 91.7% purity without post-purification processes. The system uses clean energy and water resources, simplifying product separation and purification.

Clay-assisted organic carbon burial induced early Paleozoic atmospheric oxygenation

Scientists used lithium isotope data to show that continental clay export promoted organic carbon burial and thus atmospheric oxygenation during the Cambrian period. This finding challenges traditional views on marine oxygen levels during this time, suggesting a complex interplay between oceanic and atmospheric processes.

Microfabrication makes microdroplets "pattern-obedient" but Gibbs-equation "disobedient"

Scientists have developed a method to precisely control the shape and contact angle of microdroplets, achieving arbitrary shapes and a wide range of contact angles. This breakthrough challenges the traditional Gibbs equation, which predicts contact angles for macro-droplets on rough surfaces.

Researchers improve reversibility and specific capacity of iron-based phosphate cathodes for Na-ion batteries

A new iron-based phosphate cathode material has been developed with improved reversible capacity and energy density, enabling fast-charge capability and superior cycling performance. The material uses a bi-phase intergrowth heterogeneous structure to activate the inert phase, achieving high capacity and long cycle life.

Research suggests new tool-making timeline for East Asian hominins

A new study suggests that East Asian hominins possessed advanced knapping abilities equivalent to Mode 2 technological features as early as 1.1 million years ago. The research team discovered organized flaking techniques and standardized operational processes, indicating complex mental templates among the toolmakers.

Positive associations revealed as key driver in maintaining soil biodiversity and ecological networks

Researchers analyzed 151 ecosystems across six continents to understand the intricate coexistence network among diverse species in soil ecosystems. They found that facilitative networks, characterized by positive associations, are more common than previously thought and play a key role in maintaining soil biodiversity.
