By studying the insects under more-natural conditions, scientists hope to better understand how to eradicate them — and malaria — using an emerging genetic-engineering technology called gene drives. The technique can quickly disseminate genetic modifications in wild populations through an organism’s offspring, prompting some activists to call for it to be shelved. Yet gene drives might not be as effective as activists think. Recent research has identified a major hurdle to using them to eliminate diseases and vanquish invasive pests: evolution.

Until crispr came along, biologists lacked the tools to force specific genetic changes across an entire population. But the system, which is essentially a molecular scalpel, makes it possible to alter or delete any sequence in a genome of billions of nucleotides. By placing it in an organism’s DNA, scientists can insure that the new gene will copy itself in every successive generation.

Adjustments to correct for inhomogeneities in sea surface temperatures in recent years have a large impact on the resulting decadal-scale global temperature trends. Assessing the effectiveness of these adjustments is critical to improving our understanding of the structure of modern climate changes and the extent to which trends in recent periods may have been anomalous with respect to longer-term warming.

Last week a provocative leaked memo hinted at another likely element of the incoming administration’s plan for weakening climate regulations: tweaking an obscure but increasingly utilized economic measure that tallies the costs and benefits of controlling carbon pollution.
