Climate change has contributed to the increase in the number of wildfires in the Arctic and can dramatically shift stream chemistry. Researchers at the University of New Hampshire have found that some of the aftereffects, like decreased carbon and increased nitrogen, can last up to five decades and could have major implications on vital waterways […]

Chemists have developed a protocol to rapidly produce protein chains up to 164 amino acids long. The flow-based technology could speed up drug development and allow scientists to design novel protein variants incorporating amino acids that don’t occur naturally in cells.

Small-scale gold mining in the Peruvian Amazon poses a health hazard not only to the miners and communities near where mercury is used to extract gold from ore, but also to downstream communities hundreds of kilometers away where people eat mercury-contaminated river fish as part of their diet. Downstream children under 12 with the highest […]

High-resolution imaging of the human placenta provides new insights into blood circulation patterns that are crucial for fetal development, according to a new study. These findings improve our understanding of the functioning of this understudied organ, both in healthy pregnancies and in serious medical conditions such as pre-eclampsia.

For the last eight years, the Genome Aggregation Database (gnomAD) Consortium (and its predecessor, the Exome Aggregation Consortium, or ExAC), has been working with geneticists around the world to compile and study more than 125,000 exomes and 15,000 whole genomes from populations around the world. Now, in seven articles, gnomAD Consortium scientists describe their first […]
