Artificial lake expansion amplifies mercury pollution from gold mining

Science Advances, 2020
Artificial lake expansion and high mercury loading synergistically increase mercury contamination risk from gold mining. Artisanal and small-scale gold mining (ASGM) is the largest global source of anthropogenic mercury emissions.

Targeting WEE1 in ARID1A/TP53 Concurrent Mutant Colorectal Cancer by Exploiting R‐Loop Accumulation and DNA Repair Deficiencies

Advanced Science, EarlyView.
ARID1A, a SWI/SNF complex component, is frequently mutated in colorectal cancer (CRC). CRC with ARID1A/TP53 concurrent mutations shows marked sensitivity to WEE1 inhibition. ARID1A loss induces R‐loop‐mediated replication stress, impairs ATF3 transcription, and amplifies WEE1i‐induced DNA damage, suggesting a promising therapeutic vulnerability ...

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

Advanced Science, EarlyView.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Regional distributon of mercury in sediments of the main rivers of French Guiana [PDF]

, 2014
International audienceUse of mercury (Hg) for gold-mining in French Guiana (up until 2006) as well as the presence of naturally high background levels in soils, has led to locally high concentrations in soils and sediments.

Gravity Concentration in Artisanal Gold Mining

Minerals, 2020
Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners.

Experimental Study and Industrial Application of Rigid–Flexible Coupling Screening for Difficult-to-Screen Sticky and Moist Gold Ores

Separations
Screening is a critical link in the separation of gold ores. However, issues such as the agglomeration of material masses and screen aperture blinding often lead to low screening precision and poor desliming performance, severely impacting the efficiency
