Needle‐shaped diatom frustules in food as a possible promoter of esophageal squamous cell carcinoma in coastal southeastern China: A pilot study

International Journal of Cancer, Volume 158, Issue 11, Page 2822-2828, 1 June 2026.
What's new? Esophageal squamous cell carcinoma (ESCC) incidence varies worldwide, suggesting that local environmental and dietary factors are influential. In coastal southeastern China, food products derived from small filter‐feeding fish are important dietary components, though their consumption increased ESCC risk.

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high‐throughput RNA sequencing

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Pre-Columbian land use in the ring-ditch region of the Bolivian Amazon [PDF]

, 2015
The nature and extent of pre-Columbian (pre-1492 AD) human impact in Amazonia is a contentious issue. The Bolivian Amazon has yielded some of the most impressive evidence for large and complex pre-Columbian societies in the Amazon basin, yet there ...

Anthropogenic interference and climatic change control long‐term dissolved silicate variation in the Yellow River

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Dissolved silicate (DSi) export from rivers is shaped by both natural processes and human activities. Using long‐term observations at Lijin station combined with chemical weathering and reservoir silicon cycling models, we reconstructed annual DSi fluxes and source‐sink dynamics in the Yellow River Basin since the 1980s.

Decoupling the Spread of Grasslands from the Evolution of Grazer-type Herbivores in South America [PDF]

, 2013
The evolution of high-crowned cheek teeth (hypsodonty) in herbivorous mammals during the late Cenozoic is classically regarded as an adaptive response to the near-global spread of grass-dominated habitats.

Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle

Plant Biology, Volume 28, Issue 2, Page 407-419, March 2026.
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.
